Abstract

The invention discloses shrink-proof fabric and a preparation method thereof. The shrink-proof fabric is prepared from borane coupling agent modified silica sol finished fiber fabric, and the preparation method comprises the steps of adding silica sol and a borane coupling agent into a 50%-60% ethanol water solution according to the mass ratio of 1: (0.05 to 0.1), heating to 55+ / -5 DEG C at the heating speed of 2 to 3 DEG C / min, and reacting for 4 to 5 h; and performing fiber spinning, weaving, grey cloth desizing, scouring, oxygen bleaching, tentering and whitening, printing and dyeing processing, soft setting, calendering and preshrinking, wherein the weaving adopts a warp and weft interweaving mode, and the concentration of the modified silica sol in the soft shaping working solution is40 to 60 g / L. The shrink-proof fabric can effectively reduce the shrinkage rate of the fabric and improve the dimensional stability of the washed fabric, meanwhile, the hand feeling of the fabric isnot influenced, and the fuzzing and pilling performance of the fabric further can be improved.

Description

technical field [0001] The invention relates to a fabric and a preparation method thereof, in particular to a shrink-proof fabric and a preparation method thereof. Background technique [0002] The existing shrink-proof fabrics have cumbersome operation and processing process, high fiber production cost, and cannot be really applied to actual production practice; the fabrics after finishing have poor hand feeling, which seriously affects the quality of fabrics; formaldehyde exceeds the standard and other problems.
