- the weight ratio of core filaments to wrapping fibers of the invention Coregarnes is usually 30:70 to 50:50, preferably about 40: 60.
- Soul and wrapping fibers generally differ in their Single titer. This is usually 2 to 10 dtex for the soul filaments.
- For the wrapping fiber is usually 1 to in the case of polyester fibers 2 dtex.
- the core material of the core yarn according to the invention consists of polyester specifications given above.
- the soul material is in the form of Multifilament yarns used.
- the core thread of the core yarns according to the invention can be made in principle any fibers exist.
- the term "fiber” is in its broadest To understand meaning, i.e. as multifilament or as staple fiber. Also from In terms of material, the thread is not subject to any restrictions. Leave it in the broadest sense fibers of vegetable, semi-synthetic or fully synthetic origin use, if these are suitable, the soul thread during sewing to protect.
- Examples of fibers of plant origin are cotton fibers.
- fibers of semi-synthetic origin are cellulose fibers, e.g. by the xanthate process is available.
- fibers of synthetic origin are fibers from synthetic spinnable polymers and polycondensation products, e.g. made of polyamides, Polyacrylonitrile and in particular from polyesters.
- polyester for the core material and, if necessary, the wrapping yarn come in particular those that are essentially aromatic Dicarboxylic acids, e.g. 1,4-, 1,5- or 2,6-naphthalenedicarboxylic acid, Isophthalic acid or in particular terephthalic acid and aliphatic diols with 2 to 6, especially 2 to 4 carbon atoms, e.g. Ethylene glycol, 1,3-propanediol or 1,4-butanediol can be obtained by cocondensation. Further Hydroxycarboxylic acids are suitable as starting materials for polyesters.
- Dicarboxylic acids e.g. 1,4-, 1,5- or 2,6-naphthalenedicarboxylic acid
