Method for preparing down-proof fabric

Abstract

The invention discloses a method for preparing down-proof fabric, which comprises the steps of: a, unwinding gray fabric and then adsorbing furs of the gray fabric, wherein the gray fabric is fine denier filament; b, adding the treated gray fabric into an overflow dyeing machine, carrying out high-temperature reduction operation through programmed heating; c, dyeing the gray fabric in dyeing solution; d, putting the fabric in a setting machine for setting, and then drying the fabric, and adding wind-proof agent for setting; and e, calendaring, checking the fabric, and packaging. The method disclosed by the invention has the advantages that: 1, as polyster fibers contract sufficiently under the condition of high temperature, grains on the surface of the fabric are dense and smooth; 2, the fine denier filament are applied to reacting with the polyster fibers in a certain amount of alkali solution at a high temperature, thereby slightly corroding fiber layers on the surfaces of the fibers, increasing air permeability and reducing static generation probability of the fibers, improving bulkiness of the fibers, and enhancing the sense of puffing of the fibers; 3, by adjusting tissues of the fabric, density is increased and printing and dyeing processes are adjusted, in this way, eiderdowns and wools can be prevented from penetrating down from the fabric; and 4, the fabric is excellent in performance and low in price.

Description

technical field [0001] The invention relates to a preparation method of 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. Plain weave 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.

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. Plain weave 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 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
