TEXTILE TECHNOLOGY MIXED MATERIAL FOR POLYMER WEAR-RESISTANT COMPOSITE PRODUCTS Russian patent published in 2010 - IPC D03D15/00 

FIELD: textile, paper.

SUBSTANCE: fabric made in warp and weft of twisted strands of the combined mixture of polyparaphenylene terephtalamide fiber and cotton fiber. As polymer fibers spun yarns heat-resistant fiber or mixed fiber is additionally used at a ratio of the components of tissue in mass. parts: 10-90 mass parts of polymer fiber, and the rest (till 100 mass parts) is cotton fiber. Linear density of elementary fiber yarn is 0.08-0.66 tex. Linear density of the fabric is from 10 to 100 tex. The ratio of the density of warp and weft is 0.52-2.11. The fabric contains a twisted combination yarn of linear density 18.8-172.8 tex with a twist 25-480 twists/m, the in warp the number of threads per 10 cm is from 80 to 400 and in weft the number of threads per 10 cm is from 80 to 500. The fabric is made with general weave. Fabric is produced as a tape or cloth.

EFFECT: improvement of operational characteristics of parts of friction while increasing resource exploitation; in the process of products use increase of vertical damping ability of alternating loads, improving the stability of the coefficient of friction when sliding on hardened steel as a counterface, and the possibility of reducing the intensity of linear wear of counterface material.
