LINEN-CONTAINING YARN WITH EFFECTS FOR WOVEN AND KNITTED ARTICLES AND YARN PRODUCTION METHOD Russian patent published in 2001 - IPC

FIELD: textile industry. SUBSTANCE: yarn contains polyester, polyacrylonitrile and viscose or high-modulus viscose filaments with linear density of 0.22-0.44 tex and length of 20-70 mm, 10-20% wt of modified linen filament with linear density of 0.7-1.5 tex and length of 20-70 mm and 5-15% wt of colored cotton combings. Share of chemical filaments in yarn is 75% wt. Method for producing yarn from mixed filaments involves forming roving by means of chemical filament processing equipment providing the number of twists of 22-26 per 1 m and spindle rotational speed of 800-1,100 min^-1; forming yarn with linear density of 25-50 tex at spindle rotational speed of 7,500-10,000 min^-1. According to other embodiment, method involves forming twist yarn with linear density of 50-100 tex from yarn with linear density of 25-50 tex at rotational speed of spindles on spinning-twisting machine of 6,000-7,500 min^-1. Yarn of such structure may be used for manufacture of fabric for sewing of garments, as well as knitted products. EFFECT: wider range of products manufactured from such yarn, improved appearance and increased consumer qualities of yarn and products. 3 cl, 1 tbl
