Methods of joining textiles and other elements incorporating a thermoplastic polymer material
A yarn or thread may include a plurality of substantially aligned filaments, with at least ninety-five percent of a material of the filaments being a thermoplastic polymer material. Various woven textiles and knitted textiles may be formed from the yarn or thread. The woven textiles or knitted textiles may be thermal bonded to other elements to form seams. A strand that is at least partially formed from a thermoplastic polymer material may extend through the seam, and the strand may be thermal bonded at the seam. The woven textiles or knitted textiles may be shaped or molded, incorporated into products, and recycled to form other products.
Apparatus for manufacturing double-layer fabric for down products having pattern joining line formed by high-frequency bonding
A device for preparation of double fabric for down products comprises a printing means that can print an adhesive in a predetermined printing pattern on fabric; a drying means that can dry or fix the adhesive; a laminating means that can stack and laminate the fabrics on which an adhesive is printed; and a bonding means that can bond the fabrics with a cured adhesive by pressing with a predetermined pressing means and high-frequency heating to cure the adhesive; wherein said printing pattern and the pressing pattern are the same in pattern (shape), can be overlapped on the basis of the center line and have a difference in size (width) of 20% or less. Consequently, double fabric for down products thus manufactured has an excellent adhesiveness and durability and an aesthetically excellent pattern line with good clearness and finishing quality.
Fabric having a waterproof barrier
Provided herein are waterproof fabrics that include a base fabric having a body-facing surface and an outward-facing surface, and a hydrophobic, waterproof barrier disposed on the outward-facing surface of the base fabric, a seam through the waterproof fabric, and a waterproof tape disposed on an outward-facing surface of the hydrophobic, waterproof barrier and aligned to seal the seam against water ingress. The base fabric may be a wicking fabric or may be treated with a compound that enhances wicking, and the hydrophobic, waterproof barrier may include a plastic polymer, polyurethane, polyethylene, and/or polytetrafluoroethylene. The waterproof fabrics also may include an abrasion-resistant coating and/or a durable water repellant (DWR) agent disposed on an outward-facing surface of the hydrophobic, waterproof barrier, and one or both of the abrasion-resistant coating and/or DWR agent may be discontinuous. Also provided are methods of making a waterproof fabric.
Method of making a personal protective article
A method of making personal protective equipment, such as a push-in earplug, is disclosed. The method includes the steps of covering a substrate with an outer layer that includes an unactivated foaming agent, positioning at least a portion of the outer layer in a mold, and activating the foaming agent such that a portion of the outer layer expands.
METHOD FOR SEAMLESSLY COUPLING FABRIC USING BONDING PATTERN LINE FORMED BY HIGH-FREQUENCY BONDING TECHNIQUE
The present invention can combine fabrics in a seamless manner by forming at least one bonding pattern line by a process comprising: printing and drying a heat-reactive adhesive on the inner surface of an inner fabric, and/or an outer fabric or an optional mesh material in a predetermined pattern, laminating said inner fabric, optional reinforced material and outer fabric, and then high-frequency heating them under pressing with a pressing pattern the same as the printing pattern to bond the inner fabric, and outer fabric.
Since the present invention combines fabrics by employing a high-frequency bonding manner in which a heat-reactive adhesive is used, it is possible to combine fabrics in a seamless manner with a bonding pattern line which is composed of a bonding line with excellent adhesiveness and durability and an aesthetically excellent pattern line with a good clearness and finishing quality.
STITCHBONDED THERMOPLASTIC NONWOVEN TEXTILE ELEMENTS
An article with a component joined with stitchbonding to a nonwoven textile formed from a plurality of thermoplastic polymer filaments. The nonwoven material, component, yarn, and stitch pattern can be optimized using disclosed structures and components to provide the article with desirable characteristics such as increased tensile and tear strength, improved aesthetics, moisture resistance and to limit or modify the stretch of the article in one or more directions and the like. A variety of products, including apparel (e.g., shirts, pants, footwear) may incorporate the article. In some of these products, the nonwoven textile may also be joined to the component with other bonding structures such as heat bonding, adhesives and the like.
Waterproof garment with invisible barrier seam
A waterproof invisible barrier seam is formed between two fabric laminates, an outer shell fabric laminate and an inner lining fabric laminate. The seam includes an invisible seam tape that forms a hydrostatic barrier within the seam. The design of the seam allows the formation of an effective hydrostatic barrier along the seams of a soft shell garment, while retaining flexibility, stretch, aesthetic appearance, and reversibility.
Rigid structural and low back face signature ballistic UD/articles and method of making
Fabrication of ballistic resistant fibrous composites having improved ballistic resistance properties. More particularly, ballistic resistant fibrous composites having enhanced a dynamic storage modulus, which correlates to low composite backface signature.
Removable drape fashion system
A fashion system including a shaped garment comprising a base material and a removable drape is provided herein. The removable drape may be attached to the base material such that corresponding shapes of the base material and the removable drape cooperate to hold the removable drape in place. The base material may be formed using a geometric cutting technique and the removable drape may be formed using a thermoforming technique to create a complementary drape system.
YARNS, THREADS, AND TEXTILES INCORPORATING A THERMOPLASTIC POLYMER MATERIAL
A yarn or thread may include a plurality of substantially aligned filaments, with at least ninety-five percent of a material of the filaments being a thermoplastic polymer material. Various woven textiles and knitted textiles may be formed from the yarn or thread. The woven textiles or knitted textiles may be thermal bonded to other elements to form seams. A strand that is at least partially formed from a thermoplastic polymer material may extend through the seam, and the strand may be thermal bonded at the seam. The woven textiles or knitted textiles may be shaped or molded, incorporated into products, and recycled to form other products.
