HALF-WOOLLEN FABRIC WITH COMPLEX OF RESISTANT PROTECTIVE PROPERTIES Russian patent published in 2014 - IPC D03D15/00 D03D15/08 D06M13/00 D06M13/322 

FIELD: textiles, paper.

SUBSTANCE: invention relates to the textile industry, namely, to the field of production and processing of textile fibrous materials with functional properties. Half-woolen fabric with a complex of resistant protective properties contains the yarn of the same linear density in the warp and weft. The yarn consists of wool and polyester fibres with the ratio of their average fineness equal respectively (1.05-1.28):1. The half-woolen fabric also comprises finishing material foborit R representing fluoroorganic cation-active product or its mixture with tratskan A representing an aqueous solution of quaternary ammonium salts of non-ionogenic polyesters in the amount of respectively 3.2-7.2 g/m² and 1.6-3.6 g/m². The surface density of the fabric is 200-300 g/m² at the ratio of densities equal to 1.00-1.25.

EFFECT: increased resistance to abrasion, to tensile loads, reduction of shrinkage capacity and pilling capacity, increased crumpling resistance is provided while maintaining protective oleophobic and hydrophobic properties.
