The present invention relates to a flame-retardant fabric that includes modacrylic fibers, one or more of regenerated cellulose fibers selected from the group consisting of flame-retardant rayon fibers and lyocell fibers, and polyimide fibers. The flame-retardant fabric includes the modacrylic fibers in an amount of 26 to 79 wt%, the regenerated cellulose fibers in an amount of 18 to 48 wt%, and the polyimide fibers in an amount of 3 to 26 wt%. The polyimide fibers have a fiber length of 45 to 127 mm. The char length measured by a flammability test based on GB/T 5455-1997 is 50 mm or less. The present invention also relates to protective clothing made of the flame-retardant fabric. Thus, the present invention provides a flame-retardant fabric whose char length is short in a flammability test and that has favorable flame retardancy, and protective clothing made of the flame-retardant fabric.

Process for making fibrous structures

Processes for making fibrous structures and more particularly processes for making fibrous structures comprising filaments are provided.

CARBON HOLLOW FIBRE MEMBRANE
20230249136 · 2023-08-10 ·

The present invention relates to a process for the production of asymmetric cellulose hollow fibres and the use of such fibres in the production of asymmetric carbon hollow fibre membranes (CHFMs). In particular, the present invention provides a facile and scalable process for the preparation of asymmetric CHFMs by direct pyrolysis of polymeric precursors without the need for complex pre-pyrolysis treatment steps to prevent pore collapse. The present invention also relates to the use of asymmetric CHFMs prepared according to said process in the separation of hydrogen gas from a mixed gas source, especially in the separation of hydrogen from CO.sub.2 in the steam-methane reforming reaction.

TYRE FOR VEHICLE WHEELS

A tyre for vehicle wheels comprises a carcass structure including at least one carcass ply having a plurality of hybrid reinforcing cords (10). Each hybrid reinforcing cord (10) comprises at least two strands (20a, 20b) twisted together with a predetermined twisting pitch (P). Each of said at least two strands (20a, 20b) comprises at least one monofilament textile wire made of polyester fibres and at least one multifilament textile yarn (22a, 22b) comprising a plurality of textile filaments (23a, 23b) made of aramid and/or polyester and/or rayon fibres. In any cross section of the hybrid reinforcing cord (10), said at least one monofilament textile wire is at least partially embedded in the filaments (23a, 23b) of said at least one multifilament textile yarn (22a, 22b).

Fabric made of interwoven twines

A fabric made of interwoven twines, wherein, in each case, two yarns are twisted together to form a twine and at least one of the yarns contains polyester staple fibers and cellulosic staple fibers of the types lyocell, viscose and/or modal, the share of cellulosic staple fibers in the fabric ranging from 10% by weight to 90% by weight. The fabric according to the invention is characterized in that the fabric or, respectively, those of the yarns contained therein which contain polyester staple fibers and cellulosic staple fibers as well as the twines produced therefrom comply with two relationships from which the suitability of the fabric for applications in automobiles, particularly in automobile seats, results.

Functional regenerated viscose fiber

A functional regenerated cellulose fiber includes a graphene structure and non-carbon non-oxygen elements. The non-carbon non-oxygen elements includes elements of Fe, Si, and Al. The elements of Fe, Si, and Al account for 0.018 wt % to 0.8 wt % of the regenerated cellulose fiber.

Process and device for the formation of directly-formed cellulosic webs

This invention relates to a process and a device for manufacturing cellulose-based webs which are directly formed from lyocell spinning solution and in particular for the washing of directly formed cellulose webs.

20230295847 · 2023-09-21 ·

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.

TEXTILE RECYCLING
20230374712 · 2023-11-23 · ·

A textile recycling method receives textile-waste-to-be-recycled, sorts the waste to isolate cellulose-containing articles from non-cellulose-containing articles, and re-sizes at least some of the cellulose-containing articles to create feedstock. The feedstock is processed in a cellulose solvent reactor, which has at least one ionic liquid. The ionic liquid dissolves intermolecular cellulose bonds of the feedstock to create a spinning dope. Cellulose fibers dissolved in the cellulose-bearing spinning dope solution are extruded in a cellulose coagulation bath reservoir to reconstitute at least some of the cellulose fibers, and the reconstituted fibers are wet-spun to form a continuous cellulose thread that is commercially indistinguishable from virgin fiber thread. Synthetic fiber material is vacuum-extracted or mechanically extracted from the cellulose-bearing solution and recycled into a continuous synthetic thread. Original color of textile-waste-to-be-recycled can be retained or removed, and new color can be added.
