Import-Substituting Technology for Production of Cotonized Flax for Cotton Production
The article notes the urgency of the problem of import substitution of cotton as a raw material for textile enterprises. The importance of developing new technologies focused on the use of flax in the form of modified fibers (MLF) is indicated. The efficiency of their production should be determined by cost, quality and final output. The advantages of a method based on the longitudinal plucking of fiber from a tape by means of a high-speed alternating sliding bend are revealed. Its implementation requires the use of ripening flax varieties of flax and obtaining trusts with a separability index of at least 7 units according to GOST 24383-89. In addition, mechanical upgrading of the tape by means of a promin is required before modification. These conditions provide an improvement in the properties of MLV and, especially, its potential crushability. The possibility of using MLF in the production of mixed cotton-linen yarn 50 tex thick with a flax content of ≈ 50%, suitable for the manufacture of knitwear and woven products, has been proved.
