Název v původním jazyce

Prediction of polypropylene yarn properties

Popis výsledku v původním jazyce

In this work, the possibilities of prediction of yarn properties of synthetic fibres are described. Models for calculating the yarn packing density, diameter and the relative strength of cotton yarn are described in literature. However, models do not take into account changes in the properties of yarn, which occurs in a tensile stress. Yarns from synthetic fibres are closer and more regularly arranged. Synthetic fibres are longer with lower bending rigidity and have much higher break elongation than cotton fibres. Therefore cross-section of fibre is changed during stressing therefore for prediction of yarn strength the fibres elongation factor was used. Models are verified to set POP yarn made from the same material. The experiment was prepared in order to study the effect of twist on the strength of yarn at the same yarn fineness. While studying the effect of the twist strength of POP yarn the different mechanism is comparison with cotton yarn strength was found.
