[0035] In one embodiment, the present disclosure relates to a method for improving dryness to down insulation. In some implementations of this embodiment, the method of the present technology allows to improve the overall longevity of down-filled-objects.

[0036] In one embodiment, the present disclosure relates to an article of manufacture such as, for example, a down-filled-object (e.g., jackets, duvets, pillows, sleeping bag, or the like) that has been treated by the method of the present technology.

[0037] In one embodiment, the present technology relates to a method of improving dryness to down insulation material. In some embodiments, the present technology also relates to a method that provides anti-microbial properties to the down insulation material.

[0038] In some embodiments, the method of the present technology comprises placing one or multiple layers of non-woven fabric adjacent or near the down material. The non-woven fabric is such that it extracts moisture out from the down material without condensation, based on the way specific types of fibers are deposited in a non-woven fabric structure and density of the non-woven fabric creating a low density non-woven structure. Further, the non-woven fabric may contain synthetic fibers with fine particles of natural elements such as ceramic, clay, etc., and/or with chemical anti-bacterial elements, for minimizing bacterial growth, odor, etc. Heat is retained in the garment, yet moisture is allowed to exit.

[0039] In some embodiments, the present technology enables home wash for apparel and similar products containing down feather material, because of the inherent quick drying properties provided by the low density structure. The technology may avoid the need to use a large quantity of water proof chemicals used in apparel and home fashion industry, credited to its down-proof properties. The technology helps increase the volume of down feather material after wash and dry cycles due to the rapid removal of moisture from down, allowing the hairs of the down feather material create its volume as much as possible.

[0040] In some embodiments, the present technology relates to a method of providing dryness to down insulation comprising: covering a down material with a non-woven material on at least one side of the down material; the non-woven material having sufficient density to create a low density non-woven fabric structure and being configured to extract moisture out of the down material without condensation based on the low density non-woven fabric structure; and covering the down material with the non-woven material.

[0041] In some instances, the non-woven material may further comprises fibers containing fine particles of natural elements (such as, but not limited to, ceramic, clay, or the like) and/or chemical anti-bacterial elements to control bacterial growth.

[0042] In one embodiment, the present technology relates to a method for improving dryness of down insulation, the method comprises covering the down material with a non-woven on a first-side of the down material as a first-layer, the non-woven material having sufficient density to create a low density non-woven fabric structure and being configured to extract moisture out of the down material adjacent the first-side without condensation based on the low density property from the non-woven material; and covering the down material with a non-woven material on a second-side of the down material as a second-layer, the non-woven synthetic insulation material being configured to extract moisture out of the down material adjacent the second-side without condensation also based on the low density property from the non-woven material.

[0043] In one embodiment, the present technology relates to a down-filled-object that has been treated by the method of the present technology. In some instances, the down-filled-object treated by the method of the present technology comprises a layer of down-material (which may be encased in a shell and/or lining fabric on the opposite side of the down-material) and a first layer of non-woven material located on a first-side of the down-material, wherein the down-material is covered with the non-woven synthetic insulation material on a first-side of the down-material, the non-woven material having sufficient density to create a low density non-woven fabric structure and being configured to extract moisture out of the down-material without condensation based on the low density non-woven fabric structure. The down-filled-object may further comprise a second layer of the non-woven material located on a second-side of the down-material; wherein the down-filled-object comprises a garment that is wearable in preferred embodiments or may comprise other objects such as apparel for example jackets, snowsuits, or home fashion products, or the like. Waterproofing of such objects is minimized or removed completely and longevity of down-filed items is increased as well as is the thermal efficiency during the lifetime of use (maintains resistance to transference of heat; cold spots are reinforced to provide improved warmth). The down-material may comprise natural-down-material or synthetic-thermalinsulationmaterial or other types of natural fibers such as cotton, wool, silk, etc., which may absorb moisture easily. The article described herein is able to be home-washed and is effectively windproof, water-resistant, and down-proof.

[0044] Referring now more specifically to the drawings by numerals of reference, FIGS. 1A, 1B and 1C show how a down-filled object 100 is constructed according to an embodiment of the present technology. In this embodiment, the down-filled object 100 comprises an encasing structure 110. In this embodiment, the encasing structure 110 comprises a first layer of non-woven material 112 and a second layer of non-woven material 114. In this embodiment, the first layer of non-woven material 112 and the second layer of non-woven material 114 are joined together along their periphery. In some instances, the first layer of non-woven material 112 and the second layer of non-woven material 114 are joined together by means such as, but not limited to, stitching or bonding. The joining of the first layer of non-woven material 112 and the second layer of non-woven material 114 creates a pocket 116 which is defined by the interior surface of the first and second layers 112, 114 of non-woven material. The pocket 116 is suitable to receive down-material 120. In the embodiments illustrated in FIG. 1, a first layer of shell material 130 is apposed onto the first layer of non-woven material 112 and a second layer of shell material 132 is apposed onto the second layer of the non-woven material 114. The first and second layers of shell material 130, 132 may be composed of shell fabric which may be any fabric in woven or knitted construction. In some instances, the first and second layers of shell material 130, 132 are apposed on the exterior surface of the first and second layers of non-woven materials 112, 114. In some instances, the interior surface of the first and second layers of non-woven materials 112, 114 form the wall of the pocket 116.

[0045] FIGS. 2A and 2B show a down-filled object 200 according to another embodiment of the present technology. In this embodiment, the down-material 220 is filled into a pocket 216 created by a layer of non-woven fabric 212 and a layer of woven or knitted fabric 240. In some instances, the layer of non-woven material 212 and the layer of woven or knitted fabric 240 are joined together by means such as, but not limited to, stitching or bonding. In some instances, the layer of woven or knitted fabric 240 is a shell layer. In some instances, the exterior side of the non-woven fabric 212 is covered by a layer of shell material 230. While one side of the layer of shell material 230 is facing the layer of non-woven material 212 with filling material in between when the pocket 216 is filled, the other a side of the layer of shell material 230 is facing the exterior environment.

[0046] FIGS. 3A and 3B shows a down-filled object 300 according to another embodiment of the present technology. In this embodiment, the down-material 320 is filled into a pocket 316 created by a layer of non-woven fabric 314 and a layer of woven or knitted fabric 342. In some instances, the layer of woven or knitted fabric 240 is a shell layer. In some instances, the layer of non-woven material 312 and the layer of woven or knitted fabric 342 are joined together by means such as, but not limited to, stitching or bonding. In some instances, the exterior side of the non-woven fabric 314 is covered by a layer of shell material 332. While one side of the layer of shell material 332 is facing the layer of non-woven material 314, the other a side of the layer of shell material 332 is facing the exterior environment.

[0047] In some embodiments, the down-material used for making the layer of down material may comprise natural-down-material (natural-down) or synthetic-down-material (synthetic-down) or natural fibers such as cotton, wool, silk, etc., or the like. In some embodiments, the down-material has a fill power rating of at least about 50 fill power, at least 100 fill power, at least 150 fill power, at least 200 fill power, at least 250 fill power, at least 300 fill power, at least 350 fill power, 400 fill power, at least 450 fill power, at least 500 fill power, at least 550 fill power, at least 600 fill power, at least 650 fill power, at least 700 fill power, at least 750 fill power, at least 800 fill power, at least 850 fill power, at least 900 fill power or at least 950 fill power. As used herein the expression fill power rating refers to the measure of the loft or fluffiness of a down product that is loosely related to the insulating value of the down. The higher the fill power, the more air a certain weight of the down can trap, and thus the more insulating ability the down will have.

[0048] In some embodiments, the non-woven material is a non-woven synthetic material. In some instances, the non-woven material is a non-woven insulation material. In further instances, the non-woven material is a synthetic insulation material. The non-woven synthetic insulation material is configured to extract moisture out of the down-material without condensation based on a built-in (inherent) low density non-woven fabric structure. In this way the down-material is suitably sheathed in a shell.

[0049] In some embodiments, the non-woven material has sufficient fiber density to create the desired low density non-woven fabric structure via reduction of air space within the material through the crossing of the fibers therein. Fibers used to create such characteristics of the non-woven fabric covered are of synthetic nature. In some instances, the fibers are substantially hydrophobic. Some of typical examples include, but are not limited to: polyester, polypropylene, acryl, nylon, or the like. However, some natural fibers such as cotton, wool, silk, or semi-natural fibers such as Sorona, Tencel, Rayon may be used if chemical treatment is given to remove or minimize the hydrophilic nature of the fibers. In some embodiments, the non-woven fabric making of the non-woven material of the non-woven layer has a density ranging from about 0.05 lb/ft.sup.3 and about 100 lb/ft.sup.3.

[0050] In some embodiments, the non-woven material making of the non-woven layer has a weight ranging from about 1 (one) gram per square meter (gsm) to 200 gsm.

[0051] In some embodiments, the non-woven fabric is a fabric-like material made as sheet or web structures bonded together by entangling fiber or filaments mechanically, thermally or chemically. They are flat or tufted porous sheets that are made directly from separate fibers. They are not made by weaving or knitting and do not require converting the fibers to yarn. Typically, oil-based synthetic fiber materials are used in nonwoven fabrics. Some of the common examples are Polypropylene, Polyester, Nylon, Acryl etc. Recycled fibers may be used to create similar properties and the percentage of recycled fibers may vary based upon the purposes and properties for the specific use.

[0052] In some embodiments, the surface structure of the non-woven fabric comprises randomly deposited fibers. This surface structure creates maximum surface areas between fibers and contacting down feather material and minimizes the migration of down material, which leads to improved distribution of down material in the encased structure and improved down-leak-proof. As down-leak is frequent problem when using down-filled products, manufacturers have tried to use many methods to minimize it. One of the common methods is the waterproof treatment to close the gaps between the warp and weft yarns in the fabric. However, the holes created by sewing cannot be prevented by this method and most down-leak occurs in the stitched areas as the needle leaves larger hole than the diameter of sewing thread. A bonding method instead of stitching may be adopted to prevent down-leak. However, this method creates a large surface area where down material is not present or compressed in such way that it removes the air pockets of down material, hence creates large cold spots.

[0053] Fibers in the non-woven fabric structure according to the embodiments of the present technology are more easily repositioned than other types of fabrics. When needle holes are created, the fibers of the non-woven fabric of the present technology are easily repositioned by physical forces during cut-and-sew processes and/or handling of the finished goods, caused by the fibers in the non-woven fabric being able to reposition to conform to the shape of sewing thread. The non-woven fabric structure may include another sheet of non-woven fabric, commonly known as scrim, or woven or knitted fabric. The sheet of either another non-woven fabric, woven or knitted fabric may be laminated by glue during or after the non-woven making process. Either scrim side or opposite side may face the down material. Making encasing for accepting down material may be done through either stitching or bonding or combined of the two methods in the edges and/or along the periphery.

[0054] The down-filled object of the present technology may comprise other objects (non-garments) such as bedding home fashion products, e.g., pillows, comforters, etc., and the like (sleeping bags, or the like).

[0055] In some embodiments, the non-woven synthetic insulation material further comprises the fibers containing fine particles of natural elements; wherein the fine particles of natural elements may comprise ceramic, clay or the like and/or carbon nano-particles. The fine particles of such elements are included to inhibit bacterial growth and/or to minimize odor.

[0056] In some embodiments, the present technology provides for a method of improving dryness to down insulation. The method comprises forming an encasing structure which may be filled with down material. In some embodiments, the encasing structure is formed by joining together a first non-woven layer to a second layer of non-woven material by means such as, but not limited to bonding or stitching. In some embodiments, the method further comprises apposing a first layer of shell material onto the first layer of non-woven material and apposing a second layer of shell material onto the second layer of non-woven material. The first and second layers of shell material may be composed of shell fabric which may be any fabric in woven or knitted construction. In some instances, the first and second layers of shell material are apposed on the exterior surface of the first and second layers of non-woven materials. In some instances, the interior surface of the first and the second layers of the non-woven material forms the wall of the pocket.

[0057] In some embodiments, the present technology provides for a method of improving dryness to down insulation. The method comprises forming an encasing structure which may be filled with down material. In some embodiments, the encasing structure is formed by joining together a first non-woven layer to a layer of woven or knitted fabric and joining the layer of non-woven material and the layer of woven or knitted fabric together by means such as, but not limited to, stitching or bonding. In some instances, the exterior side of the non-woven fabric is covered by a layer of shell material. While one side of the layer of shell material is facing the layer of non-woven material, the other side of the layer of shell material is facing the exterior environment.

[0058] In some embodiments, the pocket created in the encasing is filled with down-material by techniques such as, but not limited to, by hand or mechanically by for example: a blower.

[0059] It should also be noted that the steps described in the method of use can be carried out in many different orders according to user preference.

[0060] The embodiments of the invention described herein are exemplary and numerous modifications, variations and rearrangements can be readily envisioned to achieve substantially equivalent results, all of which are intended to be embraced within the spirit and scope of the invention. Further, the purpose of the foregoing abstract is to enable the U.S. Patent and Trademark Office and the public generally, and especially the scientist, engineers and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure of the application.

EXAMPLES

[0061] The examples below are given so as to illustrate the practice of various embodiments of the present disclosure. They are not intended to limit or define the entire scope of this disclosure. It should be appreciated that the disclosure is not limited to the particular embodiments described and illustrated herein but includes all modifications and variations falling within the scope of the disclosure as defined in the appended embodiments.

Example 1: Minimization of Water Retention in Treated Article

[0062] IDFL Wash Loft Test: One jacket comprising the encasing of the present technology (iDown) was tested for water retention against a regular jacket (Regular), comprising the treatment of down-proof chemicals on shell fabrics, but not comprising the encasing of the present technology. The results are presented in FIG. 4. Both the iDown jacket and Regular jackets are made by the same factory and same workers at the same time one after the other in order to keep the constructions and manufacturing techniques identical. Both the iDown and Regular jackets are weighed and volumes are measured respectively before wash, then washed in a washing machine using a gentle cycle with warm water as in customary home wash method. The jackets are then weighed before being put into a dryer to calculate the weight of water retained in the jackets. During the drying process, the jackets are weighed and measured in volume in every 30 min interval in order to measure the quantity of water removal from the jackets as well as the volume increase of the jackets. Conclusions: The iDown jacket comprising the encasing of the present technology contained 60% less water than the Regular jacket, due to the property of the low density non-woven fabric structure provided by encasing of the present technology. This may lead to the significant savings of time and electricity in washing down-filled articles at home while it is not necessary to dry-clean them to save the costs and contributing to health and environment.

Example 2: Improve Volume Recovery in Treated Article

[0063] One jacket comprising the encasing of the present technology (iDown) was tested for volume recovery against a regular jacket (Regular), comprising the treatment of down-proof chemicals on shell fabrics, but not comprising the encasing of the present technology. The results are presented in FIGS. 5A, 5B and 5C. Both the iDown jacket and Regular jackets are made by the same factory and same workers at the same time one after the other in order to keep the constructions and manufacturing techniques identical. Both the iDown and Regular jackets are weighed and volumes are measured respectively before wash, then washed in a washing machine using a gentle cycle with warm water as in customary home wash method. The jackets are then weighed before being put into a dryer to calculate the weight of water retained in the jackets. During the drying process, the jackets are weighed and measured in volume in every 30 min interval in order to measure the quantity of water removal from the jackets as well as the volume increase of the jackets. Conclusions: The iDown jacket recovers its volume much faster than the Regular jacket and it creates larger volume in a given drying time. In addition, the volume created per a unit weight of down material of the iDown jacket is larger because of increased rate of water moisture removal due to the properties of this encasing of the present technology, allowing the hairs of down material create its volume of air pockets larger than the Regular jacket.

Example 3: Quick Drying and Volume Increase of Treated Article

[0064] IDFL Thermal Resistance of Batting Systems Using a Hot Plate ASTM D1518 Option 1: Still Air Condition (IDFL Report no. 18-275235). Both the iDown jacket and the Regular jacket were measured in thermal efficiency (unit: CLO) before wash, then put in a washing process with warm water under gentle cycle, similar to customary home wash conditions. After wash, the back panels of the jackets were put on a heated plate of a test equipment in compliance with the ASTM D1518. Then, the test equipment measures the CLO values continually until the back panel is sufficiently dry to register a consistent level of CLO. The notable difference between the IDFL Wash Loft Test exemplified in the Examples 1 and 2 and this test is the fact that the former used a type of dryer used in home, allowing the articles to move within for faster exchange of heat from the dryer while the later uses the stationary hot plate to dry the contacting back panel (FIGS. 6A and 6B). Conclusions: The iDown jacket recovered its intrinsic CLO fully while the Regular shows a significant decrease in the CLO value after having reached to the state of dryness. In terms of the drying time, the iDown jacket dried 400% quicker than the Regular jacket, attributed to the ability to remove water and moisture due to the low density non-woven fabric structure covered in the encasing of the present technology. The higher rate of moisture removal of the iDown jacket leads to larger volume created by a unit weight of down material at a given drying time.
