Processing technology for warp knitting warp direction strip-type plush fabric

Abstract

The invention discloses a processing technology for warp knitting warp direction strip-type plush fabric. The processing technology comprises the following specific steps of weaving, fur splitting, dyeing, washing, softening, drying and finished product shaping. By means of the mode and the processing technology for the warp knitting warp direction strip-type plush fabric, a small circular knife is allocated to each warp direction strip-type tweed, shearing is carried out on each strip-type tweed along the warp direction middle position in the mode of shearing yarn one by one, the evenness of the length of plush is guaranteed, the original stress of the shorn plush spun polyester thread is kept, the stress between yarns on which high-temperature dyeing and shaping are carried out is not reduced, the fluff is full of fluffiness, the high-energy-consumption and high-exhaust-gas emission technology processes are reduced, the production cost is reduced, and the three-dimension, the flexible degree and the fluff flexible degree far surpass products manufactured through the traditional technology.

Description

technical field [0001] The invention relates to textile fields such as textile fabrics and clothing, in particular to a processing technology for warp-knitted warp-shaped plush fabrics. Background technique [0002] The traditional processing technology of plush fabrics adopts the high-temperature presetting of the gray cloth, and then goes through the napping machine for 6-8 times to be napped. Under the action of tension, the plush will fall down in one direction after passing through the fleece of the card clothing. The high-speed rotation of the fleece clothing makes the breaking point of the plush unstable, the length of the plush is uneven, there is no three-dimensional feeling, the fleece feels poor, and it is not fluffy enough. Due to the high temperature effect of pre-setting, its temperature far exceeds the "secondary transition point" of polyester yarn, which makes the polyester macromolecules rearranged, resulting in "stress disappearance" between yarns, which ca...

[0002] The traditional processing technology of plush fabrics adopts the high-temperature presetting of the gray cloth, and then goes through the napping machine for 6-8 times to be napped. Under the action of tension, the plush will fall down in one direction after passing through the fleece of the card clothing. The high-speed rotation of the fleece clothing makes the breaking point of the plush unstable, the length of the plush is uneven, there is no three-dimensional feeling, the fleece feels poor, and it is not fluffy enough. Due to the high temperature effect of pre-setting, its temperature far exceeds the "secondary transition point" of polyester yarn, which makes the polyester macromolecules rearranged, resulting in "stress disappearance" between yarns, which cannot be restored after dyeing and setting, resulting in a three-dimensional effect and lack of velvet
