A method for manufacturing a deodorant and antibacterial high-strength protective cloth includes: providing a first fiber thread and a second fiber thread, where the first fiber thread is a core-spun yarn formed by a blended slurry, a nano metal solution, a plurality of inorganic particles, and a plurality of thermoplastic polyurethane colloidal particles, the thermoplastic polyurethane colloidal particles are hot melted and then wrapped around a peripheral side of a core thread of the core-spun yarn for isolation from an outer wrapping layer of the core-spun yarn, and the second fiber thread is the same as the first fiber thread or is a single-thread yarn formed by the blended slurry and the nano metal solution; and intersecting and laminating the first fiber thread and the second fiber thread to form a plurality of bonding layers.

An object of the present invention is to provide a method capable of producing a protein fiber in which shrinkage at the time of first contact with moisture after production is more reliably suppressed and generation of crimp is also suppressed. A method for producing a protein fiber according to the present invention includes: a pre-shrinking step of shrinking a protein fibril in a relaxed state after drawing and before being wound; a winding step of winding the protein fibril subjected to the pre-shrinking step to obtain a wound product; and a post-shrinking step of shrinking the protein fibril subjected to the winding step in a relaxed state.

The present disclosure relates to a polyethylene fiber and a method for preparing thereof, and more particularly to a polyethylene fiber, a method for preparing thereof, and an apparatus for preparing thereof, which has excellent wearing and touch sensation with processing convenience into woven fabrics and knitted fabrics in use in applied products by reducing the stiffness of fiber having the same physical properties using an enforced necking method in a spinning process.

Compositions that include a polymer and an aldaric acid, such as glucaric acid, are disclosed. The compositions may include polyvinyl alcohol and glucaric acid. The compositions may also include polyacrylonitrile and glucaric acid. In addition, the compositions may further include lignin. Also disclosed are fibers including the compositions, methods of making the fibers, and uses of the fibers.

Soft point bonded nonwoven webs, and methods of making the same, are described that utilize a pattern of small, discrete bond points in a sequent pattern that together form macro-elements. The macro-elements are themselves positioned and aligned within a pattern such that mechanical stretching operations on the point bonded nonwoven webs yields soft and bulky fabrics but with reduced incidence of tearing or rupturing of the individual bond points.

The present disclosure relates to an elastic fiber, an elastic fiber covered yarn and reeling manufacturing methods thereof The reeling manufacturing method of an elastic fiber includes: providing an elastic fiber material, the elastic fiber material having a core portion and a skin portion, the skin portion covering the core portion; performing a first extending, to have the elastic fiber material passing a first guiding roller, the speed of the first guiding roller being 500-1500 m/min; performing a second extending, to have the elastic fiber material passing a second guiding roller, the speed of the second guiding roller being 1200-2400 m/min; and performing a third extending, to have the elastic fiber material passing a third guiding roller, the speed of the third guiding roller is 1300-2600 m/min.

The present invention relates to a device and to a method for producing a texturized filament or yarn, wherein at least one filament is guided into a draw device, is guided there by a pair of intake rollers towards at least two pairs of drafting system rollers and drawn by the same, downstream of which is disposed a texturizing device with a cooling drum. Downstream the texturizing device with the cooling drum is disposed at least one cooled drafting system roller, by which the filament, respectively the yarn is cooled to a temperature of 0° C. to 50° C.

A polyamide 46 multifilament has a strength of 6.0 to 9.0 cN/dtex and an elongation at break of 15% to 30%, an elongation rate (E′10) of less than 2.5% after heat treatment at 120° C. for 24 hours and subsequent stretching performed 10 times in a room temperature environment, and the difference (E′10-E′1) between the elongation rate (E′1) of the heat-treated fiber measured after stretching it once in a room temperature environment and its elongation rate (E′10) measured after stretching it ten times in a room temperature environment is less than 0.60%.
