Some possibilities for expanding the assortment of chemical fibres and filaments of new structures

New technological processes are described: fabrication of Lavsan-Nitron yarn from twist; fabrication of air-textured combined fibres of different raw-material composition and different linear density; fabrication of yarn using Nitron-M fibre and combined figured fibres. The technologies examined allow significantly expanding the assortment of woven and knit cloth and decreasing the specific consumption of materials and costs.[PUBLICATION ABSTRACT]
