Method for preparing down-proof fabric

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.

Method for producing polyester cotton blended spinning latitudinal elastic fabric

This invention provides a production method of stretch-yarnless cotton-polyester blended latitudinal stretch fabric. The production method successively comprises the working procedures as follows: manufacture of grey cloth, sewing of the lining side of the grey cloth, singeing of the grey cloth, desizing, sizing, coloration, preshrinking and trimming inspection. After the desizing procedure and before the sizing procedure, a slack mercerizing procedure is conducted; after the coloration procedure and before the preshrinking procedure, a slack cloth-ironing procedure is conducted. By using the trimming method, before the singeing and desizing procedures, the pick count of the cotton-polyester blended fabric is small, thereby being prone to be back-shrunk. Trough the sizing procedure, the width can be shrunk and the capillary effect is increased, then through the slack mercerizing procedure, by slackly piling in a J-shaped box and mercerizing in the condition free from latitudinal tension, the width can be sufficiently shrunk and get an excellent stretch effect. In the procedure of slack cloth-ironing, polyurethane elastomer is added to the cotton-polyester blended fabric under the condition free from latitudinal tension, and through sanforizing cotton-polyester blended fabric gets higher longitudinal elasticity.
