Embodiment Construction

[0074] In the following, the invention will be described in more detail, by means of which essential and / or quantitative data can be provided.

[0075] Process for improving the weavability of yarns made of natural animal fibres, vegetable fibres, man-made synthetic polymer fibers and / or man-made polymer fibers, which can be used in the pure state or in admixture, said process comprising the following steps:

[0076] - providing yarns made of natural animal fibres, vegetable fibres, man-made synthetic polymer fibers and / or man-made polymer fibres, usable in the pure state or in blends;

[0077] - preparation of a slurry containing a mixture of chitosan and / or derivatives thereof as reinforcing agent;

[0078] - sizing the yarn with the size to at least partially impregnate and / or coat the fibers of the yarn with the reinforcing agent, increasing the weft and / or warp yarn used in subsequent weaving weavability of the yarn.

[0079] The process is characterized in that, after ...

Abstract

A process for improving weavability of a yarn comprises a step of application of a chitosan-containing reinforcement product and a later chitosan crosslinking step.

Description

technical field [0001] The present invention relates to a process for improving the weavability of yarns, in particular of yarns made of natural animal fibres, plant fibres, man-made synthetic polymer fibers and / or man-made polymer fibres, which can be used in the pure state or in admixture The craft of spun yarn weavability. [0002] As used herein, the term weaving shall be intended to include warp and weft weaving and knitting weaving. [0003] The invention also relates to a yarn, weaving or knitting obtained by said process, and a process for improving the affinity of finished knits, knits or garments, and finished knits, knits or garments obtained by such processes . Background technique [0004] As used herein, for example: [0005] - spun yarns are intended to include all yarns with a yarn count between 50 and 200 Nm; [0006] - animal fibers are intended to include fibers obtained from insects (for example, silkworms) or fur (for example, wool, alpaca, alpaca, c...
