DE202004007660U1 - Yarn material comprises a core composed of a Elastane fiber, an inner and an outer wound fibers - Google Patents

Abstract

The yarn comprises a core, especially of Elastane (RTM; elastic fiber) fiber, an inner wound fiber, especially Skinlife (RTM; bacteriostatic polyamide) and an outer wound fiber covering, especially of textured polyamide filament. Yellowing of the inner wound fiber is prevented.

Description

The invention relates to a winding yarn consisting of three components which are arranged so that threads with Properties that the appearance of the thread, or that formed from it Finished product, negatively affect, be covered.

So far there are threads from two or three threads with a core, preferably made of elastane and one or two wrapping threads, such as Skinlife, known.

However, this thread is liable to the disadvantage at that she yellow, or become worn when using the textiles Discolor oxidation of the metal component in the thread and therefore unsightly become.

The object of the invention is therefore the process of Oxidation of the threads although not in principle prevent, but to hide the unsightly threads to the outside, thereby the discoloration of threads is not visible. The object of the invention is achieved by the characterizing part of claim 1 resolved features. The following under claims represent advantageous embodiments.

According to the invention this is solved by a winding thread is formed from three components. On a soul thread preferably elastane becomes an inner covering as more functional Thread arranged, which is spaced on the soul thread when spinning is applied. On this functional thread as an inner wrapping a covering thread is subsequently applied as an outer covering, which in turn is a cover and outer end of the 3-component thread represents which falls visually into the eye and no negative discoloration or unsightly change through oxidation that has taken place.

As a feed for this Thread is used for the soul preferably uses elastane and for the inner thread as functional Thread is used, for example, by Skinlife, which, however, comes from the outer thread, consisting of preferably textured polyamide filament yarn, is covered.

When spinning the soul thread out preferably elastane are the inner wrapping through the functional Thread as well as the outer covering applied spaced apart by the above-mentioned winding thread. In the relaxed state, both the inner winding are subsequently the functional thread, as well as the outer covering with the cover thread Location for Positioned without any distance from each other.

The invention is intended to: an embodiment are explained in more detail. In the associated The drawings show:

1 : Wrapping yarn when spinning

2 : Thread wound relaxed A thread as soul 1 comes with an inner wrapping as a functional thread 2 Mistake. This functional thread 2 is in turn with an outer covering in the form of a covering thread 3 Mistake. The following is named as a practically comprehensible exemplary embodiment:
Soul ( 1 ) 22dtex Lycra, default 3 . 43
inner wrapping PA 6.6 44f34dtex SKINLIFE
outer wrapping PA 6.6 44f34x1dtex.
700T / m, final titer 94dtex.

Claims (3)

Wrapping yarn characterized in that a soul ( 1 ) preferably consists of an elastane thread, which is covered by an inner wrapping thread ( 2 ) is wound as a functional thread, preferably Skinlife, and the thread is a further outer thread ( 3 ), which consists of preferably textured polyamide filament yarn, which the inner winding thread ( 2 ), which prevents the yellowing of the inner thread (which cannot be prevented) 2 ) as the functional thread, remains invisible. Wrapping yarn by point 1 characterized in that the inner thread ( 2 ) and the outer thread ( 3 ) spaced from each other on the core when spinning ( 1 ) is arranged. Wrapping yarn by point 1 characterized in that both the inner winding thread ( 2 ) as well as the outer thread ( 3 ) are placed close together in the relaxed state.
