DE1949829U - FINE RIB SHEET. - Google Patents

Description

The object of the innovation is a fine-rib fabric web that has good elastic properties and high shape retention. <

It is known to produce knitted, woven and knitted fabrics using core yarns, the core yarn is provided with an elastomer thread. Here, the elastomer thread is spun with a fiber sheath (core thread) Only relatively heavy textile fabrics can be produced from this.

The object of the innovation is a knitted fine rib fabric, consisting of spun or textured fiber yarn Yarn made from endless threads with an endless polyurethane thread, the proportion of which does not exceed $ 10, with a polyurethane thread in at most every second knitting system is knitted with. The production is done in such a way that the elastic polyurethane thread only has one type of needle (Dial or cylinder needle) is fed. The fiber yarn or textured yarn made from endless filaments is used in

each system is entangled in a double-faced manner. All webs can be used as fiber yarn or yarn made from endless threads Made from natural, semi-synthetic and fully synthetic fibers, pure or mixed spinning, and all of them are endless Threads - smooth or textured - of natural, semi or fully synthetic origin. As semi or fully synthetic Fäd.en or fibers can be those based on cellulose, made of polyamides, acrylonitrile polymers or polyesters will.

Basically a spun fiber yarn or a textured one endless thread used, the dm ratio to the machine division in its metr. Number or in its titer is very stocky.

Yarns are preferably incorporated whose thickness (number metric or titer) is considerably finer than the usual ones yarn to be processed lies. For example, a spun is made on a 15 fine rib machine Fiber yarn made of cotton a yarn with Nm 70/1 is used instead of the usual Nm 34/1.

The innovation results in the following advantages:

1. Permanent elasticity

2. Cooking resistance

3 · in terms of weight to comparable articles of this type without The use of elastomeric threads is much lower.
