Embodiment 1

[0054] A production method of water-soluble hot-melt fusible interlining with extremely low shrinkage rate, which sequentially includes turning thick or medium-plain fabric gray cloth, singeing, desizing and refining, bleaching, rebleaching, post-treatment, liquid ammonia finishing, Anti-shrinkage finishing, mechanical pre-shrinking, and powder coating steps; during the desizing and scouring process, the fabric is open-width padded with desizing and scouring liquid, and then steamed at 100-102°C for 60-100 minutes (Example 60, 80, 100 minutes), wash in open width, and the composition of desizing semen scouring is: sodium hydroxide 25~35g / L (for example, 25 g / L, 30 g / L, 35 g / L), scouring agent A-114 6~ 8g / L (for example, 6 g / L, 8 g / L), and the rest is water; during bleaching treatment, open-width padding oxygen bleaching solution, steamed at 100-102°C for 60-75 minutes, and open-width water washing, of which The composition of oxygen bleaching liquid is: 4.5-6.5g / L hydrogen per...

Embodiment 2

[0078] Change the rebleaching step into the dyeing step, and all the other are the same as in Example 1;

[0079] During dyeing, for the gray fabric vat dyeing process and conditions are:

[0080] Open-width cloth feeding→uniform padding and padding dye 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 padding reducing solution→under 102℃ Steam in a reduction steamer for 2 minutes → 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 The flat washing tank is washed one by one with reverse flow, and the temperature of each grid is 90-95°C, 80-90°C, 70-80°C, 70-80°C, 60-70°C, 5-30°C → 24 tins in total in two rows Forest drying → drop cloth; wherein the composition of the dyeing solution is:

Abstract

The invention discloses a water-soluble hot-melting adhesive interlining with very low shrinkage rate and a production method thereof. Dimensional change rate in the warp and weft direction after washing is -0.6%-0.5%. After the hot-melting adhesive interlining is combined with fabric through pressing, time for separating the hot-melting adhesive interlining from the fabric in 35-DEG C water is less than 15 seconds. Free and hydrolyzing formaldehyde is equal to or less than 35 mg / kg. The production method sequentially includes seam inverting, singeing, desizing, scouring, bleaching, secondary bleaching or dyeing, post-processing, liquid ammonia finishing, shrink resistant finishing, mechanical pre-shrinking and powder dot coating. The shrinkage rate in the warp and weft direction is low, water-solubility is good, the free and hydrolyzing formaldehyde amount is the minimum, and the production method is easy to operate.

Description

Technical field: [0001] The invention relates to an interlining cloth and a production method. Background technique: [0002] The existing interlinings have large warp and weft shrinkage, large amounts of free and hydrolyzed formaldehyde, and poor separation performance after the hot-melt adhesive interlining is combined with the fabric, which affects the performance and effect of high-end casual clothing. Invention content: [0003] The object of the present invention is to provide a washing dimensional change rate of -0.6% to 0.5% in the warp and weft direction; after the hot-melt adhesive interlining is combined with the fabric pressing, the separation time of the fabric at 35°C is less than 15 seconds; The production method of water-soluble hot-melt adhesive interlining with extremely low shrinkage rate of formaldehyde ≤ 35mg / kg. [0004] Technical solution of the present invention is: [0005] A water-soluble hot-melt fusible interlining with extremely low shrinkage...
