| titleOfInvention | High tenacity polyester yarn and production thereof |
| abstract | A polyester yarn having a novel property combination of high strength, high modulus and low heat shrinkage is described, which is to be produced by high-speed spinning, and a spinning yarn suitable for its production composed of a polyester raw material based on a modified polyethylene terephthalate which contains as modification components, relative to the total acid components, 0.5 - 5.0 mol % of radicals of aliphatic dicarboxylic acids having in total at least 5 C atoms and/or aromatic dicarboxylic acids whose carbonyl bonds are angled or whose aromatic rings carry modification-active substituents, and/or, relative to the total diol components, contains 0.5 to 5 mol % of alkane or cycloalkane diols having 3 to 10 C atoms, di- or tri-ethylene glycol or polyethylene glycol having a molecular weight of up to 4000, has a specific viscosity, measured in a solution of 1 g of the polyester in 100 ml of dichloroacetic acid at 25 DEG C of 0.8 - 1.7, and in that, when it is spun at a spinning take-off rate Va, the quotient Q of double refraction and crystallinity corresponds to the formula 11.86 - 3.94.10<-3> DOLLAR Va + 4.57.10<-7> DOLLAR (Va)<2> > Q > 10.86 - 3.94.10<-3> DOLLAR Va + 4.57.10<-7> DOLLAR (Va)<2> (III) |
