20220275537 · 2022-09-01 ·

The invention relates to a method for the production of lyocell staple fibers, comprising the steps in the following order: a) extruding filaments from a solution of cellulose in an organic solvent; b) precipitating the cellulose for the formation of continuous cellulose filaments; c) washing the cellulose filaments; d) contacting the cellulose filaments with a crosslinking agent; e) reacting the cellulose filaments with the crosslinking agent in a reaction chamber; f) washing the treated cellulose filaments; g) cutting the washed cellulose filaments into staple fibers; h) forming a nonwoven fleece from the staple fibers and pressing the nonwoven fleece; and i) finishing the nonwoven fleece and pressing the nonwoven fleece.

Cellulose filament process

The present invention provides a process for the viable production of lyocell cellulose continuous filament yarns.

Flame retardant mattress core cap and method of making same

A fabric made by the method of providing a non-woven batt having flame retardant fibers, stitch bonding the non-woven batt with an elastic yarn, and heat setting the stitch bonded, non-woven batt. The stitch bonded non-woven batt is exposed to a temperature in a range of 160° C. to 200° C. for a period in a range of 30 seconds to 120 seconds. In an embodiment, the fabric is adapted for use as a mattress core cover.

20210246582 · 2021-08-12 ·

The present invention provides a fabric comprising or consisting of: a first yarn comprising a fiber blend of modal and polyester; a second yarn comprising spandex; and a third yam comprising polyester. The polyester in the fiber blend may have a cross-section such as X-shape, M-shape, I-shape, honeycomb-shape, Y-shape, U-shape or O-shape that creates a plurality of spaces along the length of the first yarn that facilitate a capillary action. The modal in the fiber blend may have a cross-section that is substantially rectangular.

METHOD FOR PRODUCING A TEXTILE OBJECT HAVING ELECTROSTATICALLY CHARGED FIBRES, AND TEXTILE OBJECT
20210102318 · 2021-04-08 ·

The invention relates to a method for the production of a textile object having electrostatically charged fibres and to a textile object. A die arrangement comprising at least two separate dies or a multipolymer die is used for the production of fibres from different polymers, whereby the polymers are spaced sufficiently apart in a triboelectric series. During the process, the fibres produced from the polymers are co-mingled, at least in sections, and charged triboelectrically. Alternatively or in addition, the fibres are charged triboelectrically by means of an uncomplicated finishing process. Filters with quality factors greater than 0.2 can be produced with the textile object.
