The present disclosure relates to structures and methods of use of textiles for protection, and more particularly. relates to single layer knitted structures that can be worn as garments to block mosquito bites. The knit structures of the present embodiments can include single layer structures having a unique geometric combination of yarn properties and textiles to block mosquito bites in a single. comfortable layer of fabric. The knit structures can include one or more controllable parameters that can be adjusted to increase and/or decrease the bite blocking ability of the knit structure.

The present invention provides an elastic fiber dry spinning component and spinning part. The spinning component includes: a temperature control box (3) including a box body (31), wherein the box body (31) is longitudinally provided with multiple polymer solution channels (32) separated from each other; areas in the box body (31) other than the polymer solution channels (32) are cavities, and the cavities are used for circulation of a fluid medium that exchanges heat with an elastic fiber dry spinning polymer solution in the polymer solution channels (32); and a spinneret part (4) detachably connected to the temperature control box (3), wherein the spinneret part (4) includes multiple spinneret orifice sets (41) separated from each other, and the multiple spinneret orifice sets (41) are correspondingly in communication with outlets of the multiple polymer solution channels (32). The spinning part includes a metering device and the above-mentioned spinning component; the metering device is detachably connected to the temperature control box (3) and is used for metering and allocating the elastic fiber dry spinning polymer solution to the multiple polymer solution channels (32). The spinning component and the spinning part are convenient to install and maintain and are highly efficient.

This invention relates to a method for hiding stains in medical dressings and other textile substrates. The method includes applying a metallic silver coating to a textile substrate via a plasma enhanced chemical vapor deposition (PECVP) process. The metallic silver coating effectively hides any stain that comes into direct contact with the treated substrate by transferring the liquid beneath the surface of the coating. The invention also relates to textile substrates containing metallic silver coatings.

A polyurethane urea fiber or film is made having high elongation, low modulus, low hysteresis loss, and excellent clastic recovery. The clastic polyurethane clastic fiber or film is formed from a copolymer glycol, a diisocyanate, a chain extender and optionally a chain terminator. The hard segment content of the polyurethane fibers is in the range of 8.0-13.0% by weight.

A process is shown for providing a solid fraction from a textile product including a natural fiber, a synthetic fiber, or both. The process involves the treatment of the textile product with a water-soluble salt of dithionous acid followed by a treatment of an aprotic solvent, such as dimethyl sulfoxide.

An insect-proof, form-fitting undergarment is provided having top and bottom parts formed of selected breathable materials and having omnidirectional stretch properties, and which top and bottom parts may be securely joined at the waist to prevent insect entry. A superfine knitted fabric is utilized to prevent insect bites.

Disclosed herein is a warp knit spacer dual functional fabric construction that provides the ability to absorb sweat on one side and the ability to cool skin to below a current temperature whether wetted or dry on the other side. The knit uses four separate yarns which collectively work together to produce enhanced cooling. Knits can include warp knit spacer and circular knit spacer materials. Various finishing methods may also be employed to enhance the cooling power of the fabric.

The invention relates to a textile composite, comprising a textile substrate, which comprises a synthetic polymer and cotton, and a composition for enhancing the biodegradability of the textile substrate, wherein the composition is absorbed by the cotton.

An object of the present invention is to provide a polyurethane urea elastic fiber whose physical properties do not change much over time and which retains its initial mechanical properties, and a method for obtaining this fiber by modifying the molecular chain and ends of the polyurethane urea polymer. Another object of the present invention is to provide a polyurethane urea elastic fiber whose use can improve inventory management and fiber processing condition management, and which can be used to obtain a fabric with stable physical properties and qualities, and to provide a method for producing this fiber. The present invention is a polyurethane urea elastic fiber comprising: polyurethane urea polymer A having a molecular chain using a polymer diol, a diisocyanate, and an organic amine as starting materials, and having a primary or secondary amino group on at least one end; and polyurethane urea polymer B using a polymer diol, a diisocyanate, an organic amine, and an organic carboxylic acid as starting materials, and containing an amide bond, wherein the polyurethane urea elastic fiber contains primary or secondary amino end groups in the range of 0.1 meq or more and 20 meq or less per kilogram of polyurethane urea elastic fiber.
