Properties Of Natural And Chemical Mixture Yarns

Аннотация

The article presents the results o f experiments to determine the quality indicators of yarn produced from natural and chemical fibres on a ring spinning machine All types of natural and chemical fibres have unique properties that can be mixed in certain proportions to obtain highquality finished products with new consumer properties. Yarus used for different purposes can be made from different mixtures It is advisable to mix cotton fibre null various natural chemical fibres The influence of individual components is very important in the production of yarn, each of which gives the yarn its characteristics. Also, the hydrophobicity or roughness of the products tor rather the added fibres) causes several shortcomings if the mixing percentages and compositions of chemical and natural fibres are not selected correctly: the sanitary and hygienic properties and dyeing of linen products deteriorate, the hairs on the surface of the fabric become roundeil and its quality deteriorates. An important way to expand the range o f products is to make yarn from a mixture of natural and chemical fibres, from which the production of fabrics, knitted fabrics and knitted finished products For this purpose, mixed yams containing 50/50, 70/M) fibres of cotton and polyester, as well as 100° a polyester yarn were studied as the object of scientific research. Semifinished products -were obtained during the production process, and experimental yarn samples were taken on the Zinser-550 spinning machine in the laboratory of the Department of Spinning Technology.
