Embodiment 1

[0064] A method for producing pure cotton interlining with ultra-low shrinkage, which sequentially includes turning over seam, singeing, desizing, scouring, bleaching, mercerizing, rebleaching, drying, dyeing, post-treatment, Anti-shrinkage finishing, powder dot coating steps, also carry out mechanical pre-shrinkage before or after powder dot coating; wherein during desizing treatment, pass through rope-like padding desizing liquid, pile up for 8 to 12 hours (Example 8, 10, 12 hours), padding and washing, the desizing solution is composed of water and sodium hydroxide, the content of sodium hydroxide is 10 ~ 15g / L (eg 10g / L, 12g / L, 15g / L); during scouring, the fabric The padding scouring liquid is boiled for 5-6 hours at 120-130°C (eg 120°C, 125°C, 130°C) in a cloth cooking pot. The composition of the scouring liquid is: sodium hydroxide 12-15g / L (Example 12g / L, 14g / L, 15g / L), scouring agent A-114 2.5g / L, water glass 1.3g / L, soda ash 1.2g / L, sodium hexametaphosphate 0.4g / L, th...

Embodiment 2

[0113] A method for producing a pure cotton interlining with ultra-low shrinkage, which sequentially includes the steps of turning thin fabric gray cloth, deboiling, bleaching, re-bleaching, drying, dyeing, post-treatment, anti-shrinkage finishing, and powder coating steps. Mechanical preshrinking is also performed before or after powder coating. The specifications of the thin fabric are: the door width is 48.5 inches, and the yarn count is 60 s ×60 s , The density is 68×51 strands / inch, and the yarn twist is 119 twists / 10cm.

[0114] During the deboiling treatment, the fabric is padded with the decooking solution in open width, steamed at 100-102°C for 115 minutes, and washed in open-width water. The composition of the decooking solution is: sodium hydroxide 25-29g / L, scouring agent A -114 6g / L, the rest is water; during bleaching, open-width padding oxygen bleaching solution, steamed at 100-102°C for 65-75 minutes, and open-width water washing, so that the pH of the cloth ...

Abstract

The invention discloses a purified cotton interlining with an ultra-low shrinkage, and a production method thereof. Longitudinal shrinkage and latitudinal shrinkage of the cotton interlining are less than or equal to 0.8 percent respectively and the formaldehyde emission is less than or equal to 50mg/kg. The production method thereof sequentially comprises the steps of sewing, singeing, bleaching, mercerizing, re-bleaching, drying, dyeing, post-processing, shrink-proof finishing and powder point coating. The cotton interlining the invention has low longitudinal shrinkage and latitudinal shrinkage, good environmental protection 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 interlining has a large warp and weft shrinkage rate and a large amount of formaldehyde release, which affects the use performance and use effect of high-grade fabrics. Invention content: [0003] The object of the present invention is to provide a production method of an ultra-low shrinkage pure cotton interlining with small warp and weft shrinkage and good environmental performance. [0004] Technical solution of the present invention is: [0005] An ultra-low shrinkage pure cotton interlining is characterized in that: warp and weft shrinkage ≤ 0.8%, release of formaldehyde ≤ 50mg / kg. [0006] The gray fabric of the interlining is thick fabric, medium flat fabric or thin fabric; wherein the thick fabric is one of the following two specifications: the first one has a width of 48.5 inches and a yarn count of 12 s ×12 s , the density...
