CS264202B1 - Yarn containing split torn fibers - Google Patents

Abstract

) Yarns made from 100% split fibres, or from a mixture with natural or conventionally spun fibres, have new improved properties due to the different surface of the split fibres, i.e. usually a quadrangular cross-section and short spines on the surface of the fibres. They are intended for use in everything from hand-knitting yarns to clothing knits, furniture fabrics to textiles for technical use. They can be produced as effective ones, especially with a “hair-mohair” or a jacquard effect. In the case of smooth yarns, subsequent combing can achieve further splitting of the protruding fibres and a pleasant soft hair effect.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to staple fiber yarn, optionally mixed with conventional natural or chemical fibers with different properties and / or different surfaces.

Known filament yarns produced hitherto have a completely different character from those of commonly spun chemical fibers or natural fiber yarns because they consist of a system of split fibers having irregular transverse bonds between them, so that the whole system is essentially an infinite formation without the free ends of the individual fibers. To obtain the yarn, the split fiber system is usually twisted.

It is an object of the present invention to utilize in short filament yarns the known properties of short filaments as in conventional yarns and, at the same time, the specific filament properties of POL, PAD, PES or PES. mixed POL films resulting from their different geometry, ie generally quadrangular cross-section. To this end, the split fiber system is torn on a shredder converter into fibers of variable staple length in the range of 20-200 mm. Their surface exhibits short barbs due to the tearing off of the transverse splitting of the original split filament system and the ends of the filaments are characterized by elongated tips due to the elongation to break. Both of these specific characteristics of the staple split fibers largely contribute to the novel properties of the spun yarns. The spines of the surface of the fibers provide greater stability to the fibers in the yarn, while refining the ends of the fibers protruding from the yarn body gives the yarn a pleasant soft touch.

The softness of the yarns according to the invention can be further increased by combing them, not only releasing the other ends from the yarn surface, but also further splitting the ends, thereby producing a higher number of protruding fibers from the yarn surface than the number of staple filaments in the yarn.

Accordingly, the present invention relates to a yarn comprising split torn fibers characterized in that it consists of split fibers torn to a staple with an elongated tip and an irregular length of 20 to 200 mm, optionally in admixture with 5 to 95% by weight of natural or chemical fibers, of the yarn body.

The filament yarns of the present invention can be made smooth or fancy, especially with a "hair" or flax effect. Spun yarns are sufficient for the production of fancy yarns. The yarns can also be made with an admixture of natural or classically spun chemical fibers of different fines and lengths. The proportion of staple split fibers depends on the desired surface effect of the yarn, while natural and / or chemical fibers determine the basic nature of the yarn for a given field of use.

The yarns of cotton, wool and linen character can be spun by both classical and unorthodox spinning technology using filament yarns or dyed with selectable staple length and a wide range of finenesses.

The production possibilities of filament yarns according to the invention are obvious from the following examples:

Example 1

Semi-combed yarn for furniture fabrics of fineness 168 tex spun from 100% POP staple fiber staple length 65-110 mm dyed in the mass.

Example 2

Mixed semi-combed yarn for furniture fabrics of fineness 500, tex from a mixture of 50% VS cuts fineness of 7.2 dtex, length 100 mm / 50% POP staple split fibers staple length 55 to 110 mm gray.

Example 3

Blended semi-combed hand knitting yarn Romance fineness 84 .tex from blend 20% wool NZ 48 'combed, gray / 60'% PAN staple Wolpryla fineness 5,6 dtex, length 100 mm in the form of comb / 20% POP staple fiber length .65 —110 mm gray.

Example 4

Mixed carded hand knitting yarn Golem fineness 400 tex from blend 20% wool NZ 48 'washed / 20% wool 56750' washed / 40% PAN staple fineness 5,6 dtex length 100 mm / 20% POP chopped fibers staple length 55-110 mm dyed in the mass.

Example 5
