Embodiment 1

[0042]A production method of pure cotton bleached hot-melt fusible interlining with extremely low shrinkage rate, which sequentially includes turning thick or medium plain fabric gray cloth, singeing, desizing, scouring, bleaching, rebleaching, post-treatment, liquid Ammonia finishing, powder coating, anti-shrinkage finishing steps; during desizing treatment, the desizing solution is passed through rope padding, stacked for 8 to 12 hours (example 8, 10, and 12 hours), padding is washed, and the desizing solution is made of water Composed of sodium hydroxide, the content of sodium hydroxide is 10 ~ 15g / L (for example, 10g / L, 12g / L, 15g / L); during scouring, the fabric is soaked in the scouring solution, and the fabric is boiled in the cloth pot Scouring at 120~130°C (for example 120°C, 125°C, 130°C) for 5~6 hours, the composition of the scouring liquid is: sodium hydroxide 12~15g / L (for example 12g / L, 14g / L, 15g / L), scouring agent A-114 2.5g / L, water glass 1.3g / L, soda ash 1.2g...

Embodiment 2

[0067] A production method of an ultra-low shrinkage pure cotton interlining, which sequentially includes the steps of turning over the thin fabric gray cloth, deboiling, bleaching, re-bleaching, post-treatment, liquid ammonia finishing, shrink-proof finishing, and powder coating. Mechanical pre-shrinkage is also performed before and after spot 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.

[0068] 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...

Abstract

The invention discloses a pure cotton bleached thermal smelting adhesive lining with extremely low washing shrinkage. The adhesive lining is characterized in that the warp-wise and zonal washing dimensional change rate is larger than or equal to minus 0.5%; the quantity of the formaldehyde released by the interlining is less than or equal to 35mg / kg; and the peeling strength is larger than or equal to 12N; the warp-wise and zonal dry heat dimensional change rate is larger than or equal to minus 0.8%. The production method of the invention comprises the following steps in sequence: overedging,singeing, bleaching, stoving, re-bleaching, liquid ammonia finishing, shrink resistant finishing, powder point coating and compressive shrinkage. The invention has the following advantages: the warp-wise and zonal washing dimensional change rate is large; the peeling strength is high; the environmental-friendly performance is good; and the production method can be easily operated.

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 object of the present invention is to provide a production method of an ultra-low shrinkage pure cotton interlining with a warp and weft washing dimension change ≥ -0.5%, high peeling strength and good environmental performance. [0004] Technical solution of the present invention is: [0005] A pure cotton bleached hot-melt adhesive interlining with extremely low shrinkage rate, characterized by: the warp and weft washing dimensional change rate ≥ -0.5%, the amount of formaldehyde released from the interlining ≤ 35m...
