20220010464 · 2022-01-13 ·

A method for recycling a nonwoven fabric, including: a waste nonwoven fabric pulverization step of pulverizing a waste nonwoven fabric to obtain pulverized waste nonwoven fabric particles; a material mixing step of dispersing and mixing the pulverized nonwoven fabric particles and a filler in water to obtain a nonwoven fabric mixture; a raw material mixing step of adding a fixing agent for agglomeration of the pulverized waste nonwoven fabric particles and the filler to the nonwoven fabric mixture, followed by mixing, to form a raw material; a draining step of separating and removing water from the raw material to form a recycled nonwoven fabric sheet; a first lamination step of laminating the plurality of recycled nonwoven fabric sheets to form a laminate; and a compressing/dehydrating step of compressing and dehydrating the laminate.

FIBERS, WOVEN FABRICS INCLUDING THE FIBERS, AND METHODS OF MANUFACTURING THE SAME
20210340695 · 2021-11-04 · ·

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.

Flame retardant viscose fiber

A flame retardant fabric is directly woven from flame retardant viscose fiber added with inorganic silicon for covering the outside of flammable articles, wherein the flame retardant viscose fiber having denier, strength and flame retardant effect which use silicic acid as the flame retardant, and coating a layer of organic material, melamine flame retardant resin on the surface of silicic acid, and then preparing the flame retardant viscose fiber into an nano-sized particles. The flame retardant fabric has a fineness of 1.11 to 2.78 dtex, and a strength of ≥2.0 cN/dtex, which meets the production requirements of spinning, and does not need to be blended with other high-strength fibers when spinning, and the woven fabric from the flame retardant viscose fiber does not need to be flame retardant, so that the flame retardant fabric has a good flame retardant effect and saves costs through simply the production process.
