Problems solved by technology

However, due to the poor strength of pure cotton spinning and the high weaving density, the warp and weft density are more than 100. Poor, leading to the production difficulty and processing quality of its subsequent processing procedures, product quality is low, and the price is high, which affects people's use of cotton down-proof fabrics
[0003] Cotton down-proof fabrics are mainly plain weave, which is a fabric formed by interweaving warp yarns and weft yarns up and down. It is characterized by many interweaving points, smooth surface and good wear resistance. The coating is anti-feather, and the hand feels too hard; the air permeability is too high, and the effect of anti-down and wool is not good
[0004] Chinese patent 200710113590.9 discloses a production method of high-count and high-density feather-proof cloth, which mainly involves sizing the gray cloth, adopts double dipping and double pressing, and adds smoothing agent and penetrating agent to the sizing slurry. Its advantages are: It is easy to operate and the cloth surface is smooth and even, but its disadvantage is that it has poor air permeability and is not resistant to down and wool
[0005] CN202786635 (2013-3-13) discloses a soft silk feather-proof fabric, but the air permeability of the fabric needs to be improved

Embodiment 1

[0045] The gray cloth is an elastic satin made of cotton, low-elastic network silk, bamboo fiber, and spandex. The warp direction of the satin is a blended yarn formed of cotton fiber and bamboo fiber. The content of cotton fiber is 50%, and the content of bamboo fiber is 50%. The weft direction is low elastic network yarn and spandex covered yarn.

[0046] And the blended yarn formed of cotton fiber and bamboo fiber is treated with bamboo vinegar. The bamboo vinegar treatment includes the first bamboo vinegar treatment and the second bamboo vinegar treatment. The first bamboo vinegar treatment is to immerse the blended yarn in 60 ° C. In the first bamboo vinegar treatment solution for 10min, the second bamboo vinegar treatment is to immerse the blended yarn in the second bamboo vinegar treatment solution of 85°C for 3min, the first bamboo vinegar treatment solution is a bamboo vinegar aqueous solution of 20g / L, and the second bamboo vinegar treatment solution is 20g / L.

Abstract

The invention relates to a textile and in particular relates to a down proof fabric. The down proof fabric is prepared by the following steps: selecting a gray fabric; sanding; rolling a down proof finishing agent at the processing speed of 60-80 m / min, namely ensuring that a sanded fabric passes through a down proof finishing agent aqueous solution at the temperature of 40-55 DEG C with the pick-up of 45%-65%, wherein the down proof finishing agent comprises a starch composite catalyst and a compound, and the compound is formed by compounding an acrylic acid acrylamide compound with a hydrophilic softening agent KF-896 in a mass ratio of (2-5):1; dyeing, namely immersing in a dye liquor, reducing and steaming, washing, oxidizing, washing, soaping, washing, drying and rolling up, wherein the dye liquor comprises dye, sodium sulphide, a wetting agent and sodium carbonate, and the thickness pick-up of the dye liquor is 60%-70%, a reducing and steaming temperature is 90-100 DEG C, and reducing and steaming time is 40-50 seconds; printing at the temperature of 100-115 DEG C; calendaring at the temperature of 105-115 DEG C and at the processing speed of 30-50 m / min; preshrinking; and after finishing. The prepared down proof fabric has excellent air permeability and an excellent effect of preventing down feather from unthreading.

Description

technical field [0001] The invention relates to a textile, in particular to an anti-down fabric. Background technique [0002] High-density down-proof fabric is a fabric with a large demand and is widely used in the current market. After printing and dyeing, the fabric has the characteristics of soft texture, smooth surface, uniform surface and clear lines. However, due to the poor strength of pure cotton spinning and the high weaving density, the warp and weft density are more than 100. Poor, leading to the production difficulty and processing quality of its subsequent processing procedures, product quality is low, and the price is high, which affects people's use of cotton down-proof fabrics [0003] Cotton down-proof fabrics are mainly plain weave, which is a fabric formed by interweaving warp yarns and weft yarns up and down. It is characterized by many interweaving points, smooth surface and good wear resistance. The coating is anti-feather, and the hand feel is too h...
