Embodiment 1

[0055] A production method of an extremely low shrinkage pure cotton oil-resistant and anti-fouling anti-fouling hot-melt adhesive interlining, which sequentially includes turning over the thick or medium plain fabric gray cloth, singeing, desizing, scouring, bleaching, rebleaching, and post-processing. Treatment, liquid ammonia finishing, anti-oil, anti-fouling and anti-shrinkage finishing, post-baking, powder coating, mechanical pre-shrinking steps; during the desizing treatment, the fabric is passed through the rope padding desizing solution, and stacked for 8 to 12 hours (Example 8, 10, 12 hours), padding and washing, desizing liquid is made up of water and sodium hydroxide, and the content of sodium hydroxide is 10~15g / L (example 10g / L, 12g / L, 15g / L); During the scouring process, the fabric is soaked in the scouring liquid, and scoured for 5 to 6 hours at 120-130°C (for example, 120°C, 125°C, 130°C) in a cloth cooking pot. The composition of the scouring liquid is: Sodium...

Embodiment 2

[0082] Change the rebleaching step into the dyeing step, and all the other are the same as in Example 1;

[0083] During dyeing, for the gray fabric vat dyeing process and conditions are:

[0084] Open-width cloth feeding→uniform padding and dyeing solution→two rows of infrared pre-drying→two groups of 70~80℃ hot air pre-drying→one group of cylinder drying→cloth falling→uniform padding and color-fixing solution→102℃ Steam in a reduction steamer for 2 minutes to fix the color → wash in cold water at 5-30°C in two compartments → oxidize with ventilation → oxidize with hydrogen peroxide at a concentration of 0.5-1g / L → soap boil in two compartments with a soaping agent with a concentration of 2-3g / L , → Six-compartment flat washing tank for backflow washing one by one, the temperature of each compartment is 90-95°C, 80-90°C, 70-80°C, 70-80°C, 60-70°C, 5-30°C → two rows total 24 cylinders drying → drop cloth; wherein the composition of the dyeing solution is:

Abstract

The invention discloses a low-shrinkage pure-cotton oil fouling resistant hot-melting bonding lining and a production method thereof. The low-shrinkage pure-cotton oil fouling resistant hot-melting bonding lining is characterized in that the warp-direction and weft-direction washing size change rate is not less than minus 0.6 percent, the oil resistance is not less than120 scores, the lining cloth formaldehyde release amount is not more than 40mg/kg, the peeling strength is not less than 12N and the warp-direction and weft-direction dry heat size change rate is not less than minus 0.8 percent. The production method of the invention sequentially comprises the steps of turned sewing, singeing, desizing, boiling, bleaching, re-bleaching or dyeing, aftertreatment, liquid ammonia finishing, oil fouling and shrinkage resistant finishing, post baking, powder point coating and mechanical pre-shrinkage. The invention has the advantages of large warp-direction and weft-direction washing size change rate, high oil fouling resistance, high peeling strength, high environmental-friendly performance and easy operation of the production method.

Description

Technical field: [0001] The invention relates to an interlining cloth and a production method. Background technique: [0002] The existing interlinings have a small rate of dimensional change in the warp and weft direction for washing, a small rate of dimensional change in the warp and weft direction for dry heat, and a large amount of formaldehyde release, which affects the use performance and use effect of high-grade fabrics. Invention content: [0003] The purpose of the present invention is to provide the production of a pure cotton oil-resistant and anti-fouling hot-melt adhesive interlining with a water-washing size change of ≥-0.6%, good oil and anti-fouling, high peeling strength, and good environmental performance and extremely low shrinkage in the warp and weft direction. method. [0004] Technical solution of the present invention is: [0005] A pure cotton oil-resistant and anti-fouling anti-fouling hot-melt adhesive interlining with extremely low shrinkage r...
