The present invention relates to yarn dyeing, such as denim dyeing. A process provides a dyed yarn having reduced dye penetration and a white core at lower cost. The improved process for yarn dyeing is referred to herein as the CleanKore technology. The CleanKore technology improves one or more steps in dye ranges to achieve dyeing of the yarn while retaining a white core at the center of the yarn. When viewing a cross-section of a yarn, the peripheral portion is dyed while the center remains white (not dyed). The CleanKore technology modifies the scouring stage (or phase), the scour rinsing stage, the dyeing stage, and/or the dye rinsing phase of existing dye ranges. The modifications may be applied individually or any combinations thereof to the existing dye range.

A woven stretchable fitted sheet is made of a woven material but is stretchable in one dimension. The fitted sheet is made of a single such material comprising the top wall and side walls combined together to form a skirt. The edges of the skirt have an elastic band attached thereto which bunches up the material slightly to allow it to be stretched over a mattress and to accommodate to mattresses of differing heights. The fabric preferably used to manufacture the fitted sheet includes a blend of a material such as cotton or cotton/polyester blend blended with SPANDEX® elastic yarn. These materials are made into a yarn using a core spinning technique. In the preferred embodiment, the blend of cotton or other fabric and SPANDEX® is from 2 to 20% SPANDEX® and the remainder cotton or other material, such as, for example, a cotton/polyester blend.

The present subject matter discloses a fabric weaving method and apparatus therefor, wherein the method includes forming a fabric where the warp ends of the fabric is made of multifilament polyester yarns and the weft picks are made of cotton or regenerated cellulose fiber or linen fiber or a combination thereof. The woven textile fabric has 50-160 EPI of multifilament polyester yarns of denier within a range of 75D-200D with 7-250 filaments in each polyester yarn, wherein one or more yarns per dent is setup in the reed apparatus of the warp of the loom apparatus. Further, the woven textile fabric comprises of 50-91 picks per inch of cotton or regenerated cellulose fibre or linen fiber or a combination thereof and of 20-50 count (NE). Furthermore, the total cover factor of the woven textile fabric is 10-38, wherein the warp cover factor is 8-19 and the weft cover factor is 10-19.

A fabric having particularly good translucent properties with regard to UVA and UVB radiation, in particular for use in garments for the sport and leisure sector, with the transparency being reduced at the same time. The fabric comprises a first yarn made of cellulose-based fiber or regenerated fiber, and a second yarn made of polymer fiber. The proportion by weight of the first and second yarns is at least 80% by weight. The wale density is in the range from 10 to 30 per cm and the course density is in the range from 15 to 33 per cm. The second yarn has a fineness in the range from 45 to 300 dtex and the first yarn has a fineness in the range from 150 to 300 dtex. The grammage of the fabric is between 70 and 150 g/m{circumflex over ( )}2.

A method includes forming a multi-pick yarn package through winding multiple oriented yarns onto a spool. The multiple oriented yarns serve as weft yarns forming adjacent substantially parallel yarns wound together, and each of the multiple oriented yarns is formed through drawing each of multiple synthetic yarns from a corresponding supply package. The method also includes simultaneously inserting the weft yarns in a single pick insertion event of a pick insertion apparatus of a loom apparatus in which the simultaneously inserted weft yarns are to be conveyed through a set of warp yarns to produce an incremental length of a woven textile fabric.

A method includes drawing each multiple partially oriented polyester yarn from a corresponding supply package to form an oriented polyester yarn as a single multi-filament polyester weft yarn, inserting the multi-filament polyester weft yarn during a single pick insertion event of a pick insertion apparatus of a loom apparatus through winding the multi-filament polyester weft yarn on a single-pick yarn package, and conveying at least two of the multi-filament polyester weft yarn across a warp shed of the loom apparatus through a set of warp yarns in the single pick insertion event to form an incremental length of a woven textile fabric having a first surface with a majority of ends of the warp yarns and a second surface with a majority of picks of the multi-filament polyester weft yarn thereon. The method also includes solely abrading the second surface to provide for comfort to a user during contact therewith.

Fibers, yarns, woven fabric including the yarns and fibers, and methods of manufacturing the same are disclosed. Fibers can include base material staple fibers and dissolvable or water-soluble fibers. At least the base material staple fiber is mixed and cleaned to form a base material web or sliver. The clean base material web or sliver is then intimately mixed with the dissolvable fibers in a blow room to form a homogenously-mixed base material/dissolvable material sliver. The homogenously-mixed base material/dissolvable material sliver is then blended again during drawing so as to produce a twice-mixed, ultra-homogenous yarn comprising base material and dissolvable material. A processing step can allow for removal of the dissolvable fibers to produce a yarn defining a plurality of pores that are uniformly distributed throughout the structure of the yarn.

The present disclosure generally relates to a device for dewatering a material. The device comprises a biodegradable, permeable enclosure configured for receiving the material through an inlet. The permeable enclosure comprises layered biodegradable textiles, an inner portion and an outer portion, derived from renewable resources. The inner portion has an apparent opening size between about 0.5 mm and 3 mm. The outer portion has a ratio of the minimum tensile strength in the warp direction to the minimum tensile strength in the weft direction of about 2.5.
