Protective textile with tungsten and manufacturing method thereof
In one aspect, a method of manufacturing a protective textile may include steps of (a) twisting a first yarn with a tungsten filament; and (b) using a second yarn to cover the yarn-tungsten product generated in step (a). The yarn generated in step (b) is further twisted with an elastic spandex. In one embodiment, the first yarn is selected from a group of Nylon, Polyethylene Terephthalate (PET), cotton yarn, bamboo fiber and Tencel. In another embodiment, a Polyethylene (PE) fiber is the second yarn, and the third yarn may include Nylon, PET or PE. The protective textile is advantageous because it is light, thin, soft and highly cut resistant. Also, it has great electrical conductivity and chemical stability, and it is not easy to deform after washing.
Wet-activated cooling fabric
Disclosed herein is a knitted multi-layer fabric construction that provides the ability to cool skin to below a current temperature whether wetted or dry. The knit uses four separate yarns which collectively work together to produce enhanced cooling. Knits can include warp knit, seamless, hosiery, flat bed, spacer, and double knits. Various finishing methods may also be employed to enhance the cooling power of the fabric.
ALGINATE-BASED POLYMERS AND PRODUCTS, AND THEIR MANUFACTURE
Polymers comprising an alginate which is ionically crosslinked with unsubstituted dicarboxylate-bridged multivalent cations, products including such polymers, and methods of their manufacture.
Composite stretch yarn, process and fabric
In a stretch yarn (1) comprising a stretchable core (2) covered by an inelastic fibers sheath (3) the stretchable core (2) comprises first and second fibers (4, 5) that have elastic properties, the first fiber (4) is an elastomer and the second fiber (5) is a polyester based (co)polymer, the amount of the second fiber being in the range of 60-90% (w/w) of the total weight of the fibers of the stretchable core (2); the first and second fibers are connected together at least at a plurality of points (P).
COMPRESSION HOSIERY
A compression hosiery garment includes a knit fabric including a first yarn and a second yarn knit in an alternating knit construction and having at least one course of the second yarn for each course of the first yarn. The first yarn includes a covered yarn with an elastic core, such as a soft modulus elastic core, and the second yarn includes an inelastic yarn. The alternating knit construction includes an inverse course shift, where the first yarn is knit with a first course height that is greater than a second course height of the second yarn.
POLYESTER COTTON-LIKE YARN-DYED FABRIC, AND MANUFACTURING METHOD AND APPLICATION THEREOF
Disclosed are a polyester cotton-like yarn-dyed fabric, and a manufacturing method and application thereof. The polyester cotton-like yarn-dyed fabric is interwoven by warp and weft, the warp adopts dyed polyester as a covering layer and low-temperature spandex as a core-spun yarn of a core yarn, a weight ratio of the polyester to the low-temperature spandex is 4-49:1, and the polyester is subjected to alkali deweighting treatment to form an eroded surface. The polyester cotton-like yarn-dyed fabric has good cotton feeling, high elasticity, high color fastness and low ironing shrinkage rate, and is suitable for making high-quality clothing, especially shirts. The manufacturing method of the yarn-dyed fabric is energy-saving and emission-reducing, and can manufacture a novel polyester yarn-dyed fabric with low ironing shrinkage rate, high color fastness and cotton-like hand feeling. Use of the yarn-dyed fabric for making clothing such as shirts increases the selectivity and functionality.
PROTECTIVE WOVEN FABRIC
A woven fabric having warp yarns and weft yarns, wherein said warp yarns and said weft yarns comprise a core and a sheath, said core comprising a first core component and a second core component, wherein the first core component has a breaking tenacity, measured with DIN EN ISO 2062, of at least 6 g/den, more preferably of at least 10 g/den, more preferably of at least 14 g/den, even more preferably of at least 20 g/den, wherein the second core component comprises elastomeric elements, and wherein elasticity of the fabric in warp direction is at least 20% (measured according to ASTM D3107) and elasticity of the fabric in weft direction is at least 20% (measured according to ASTM D3107).
Polyurethane Elastic Yarn and Manufacturing Method Thereof
To provide a polyurethane elastic yarn that is superior in unwinding properties and adhesive properties in respect to a hot melt adhesive agent, and to provide a manufacturing method thereof. A polyurethane elastic yarn wherein the main structural component of the polyurethane is a polymer diol or diisocyanate; and includes a polymer that includes, as the main structural unit, a structural unit that uses an aromatic olefin and/or an aliphatic diolefin as a monomer, and is partially hydrogenated or completely hydrogenated.
Fusible bicomponent spandex
Included are segmented polyurethane elastic fibers or spandex fibers, capable of bonding to polymer fiber such as nylon or polyamide fibers, in addition to bonding to itself, for apparel textile applications. More particularly the invention relates to bicomponent spandex fibers, with a heat resistant core and a heat sensitive sheath, spun from polymer solutions. The nylon fabrics containing such spandex fibers have enhanced stretch performance and improved surface appearance after heat treatment to activate the fusing and bonding between nylon fibers and spandex fibers.
Core-free thermoplastic polyurethane yarn with added nanosilica
The present invention provides a resin for thermoplastic polyurethane (TPU) yarn using nanosilica and a method for manufacturing the same. Nanosilica having a particle size of 100 nm or less is added as a thickening agent for improving productivity and glossiness of TPU yarns, such as mono-filament TPU yarns having a denier count of 50 to 350 or multi-filament TPU yarns having a denier count of 50 or less. No TPU coating is needed for applying to the surface of polyester or nylon yarns, thereby securing desired workability and properties and realizing continuous drawing of TPU yarns without thread breakage. The content of nanosilica at least from 0.1 or 0.3 to 7 phr, or a non-zero content of 7 phr or less in TPU resin is optimal for productivity of mono- or multi-filament yarns. The content of nanosilica from 0.5 to 1.5 phr is optimum for both productivity and cost reduction.
