Problems solved by technology

[0004] Judging from the current form of commercial product development, knitted fabrics are the main form. This is because there are no principled technical obstacles in the processing of colored cotton knitted fabrics. First, the processing technology of knitted fabrics is relatively simple and does not need to be processed like woven fabrics. There are many technical auxiliary measures; secondly, knitted fabric products are mainly casual clothing and underwear. Since the products already have colors, there are no specific technical processing requirements such as finishing and dyeing; Development in the direction of chemicalization and processing refinement, products do not require non-iron finishing

Embodiment 1

[0015] Homemade green colored cotton plain weave grid woven fabric (fabric weight 156g / m 2 ), the warp yarn is a strand, and it adopts size-free weaving, so the fabric does not need to be desized. The crease recovery angle of the fabric is 134 degrees (warp + weft), without scouring and finishing, and the wool effect of the fabric is 2.1cm. Finishing conditions: BTCA concentration 6%, sodium hypophosphite concentration 4%, mass ratio of BTCA to sodium hypophosphite 3:2, osmotic wetting agent (JFC) concentration 1%, 70°C double dipping and rolling, liquid carrying rate 85% %, bake at 90°C for 2 minutes, and at 180°C for 2 minutes. After finishing, wash once on the washing machine with ordinary washing powder to remove unreacted chemicals and catalysts. After finishing, the crease recovery angle of the fabric is 243 degrees (longitude + weft), the fabric strength remains 48%, and the crease recovery angle after 30 household washings is 210 degrees. After finishing, the crease ...

Embodiment 2

[0017] Homemade green colored cotton plain weave grid woven fabric (fabric weight 156g / m 2 ), plain weave, the warp yarns are strands, and size-free weaving is adopted, so the fabric does not need to be desized, the crease recovery angle of the fabric is 134 degrees (warp + weft), and the hair effect of the fabric is 2.1cm. Finishing conditions: 6% BTCA concentration, 4% sodium hypophosphite, 0.5% penetrating agent and wetting agent (JFC), 1% silicone softener, double dipping and rolling at 70 ° C, liquid retention rate of about 85 %, drying at 90 ° C 2 minutes, bake at 180°C for 2 minutes. After finishing, wash once on the washing machine with ordinary washing powder to remove unreacted chemicals and catalysts. After finishing, the crease recovery angle of the fabric is 271 degrees (warp + weft), the fabric strength remains 45%, and the crease recovery angle after 30 household washings is 242 degrees. After finishing, the increment of crease recovery angle of the fabric rea...

Embodiment 3

[0019] Homemade green colored cotton plain weave grid woven fabric (fabric weight 156g / m 2 ), plain weave, warp yarns are strands, and size-free weaving is adopted, so the fabric does not need to be desized. The crease recovery angle of the fabric is 134 degrees (warp + weft), without scouring and finishing, and the gross effect of the fabric is 2.1cm. Finishing conditions: 3% BTCA concentration, 2% sodium hypophosphite concentration, 3:2 mass ratio of BTCA to sodium hypophosphite, 0.5% osmotic wetting agent (JFC) concentration, two dipping and two rolling at 70°C, liquid carrying rate 85% %, bake at 90°C for 2 minutes, and at 180°C for 2 minutes. After finishing, wash once on the washing machine with ordinary washing powder to remove unreacted chemicals and catalysts. After finishing, the crease recovery angle of the fabric is 231 degrees (warp + weft), the fabric strength remains 55%, and the crease recovery angle after 30 household washings is 192 degrees. After finishing...

Abstract

The invention discloses a method for trimming a naturally colorful easy-care cotton fabric ecologically, which comprises the following steps: using BTCA polyhydric carboxylic acid as easy-care finishing agent which density is 2-8%, arranging the catalyst density at 1-4% and the density percentage ratio of the easy-care finishing agent and the catalyst between 3:1 and 3: 2, charging penetration humectant which density is 0.5-2%, doing double-nip-double-dip process in the condition of 50-90 DEG C, obtaining the fabric fluid-carrying ratio at 70-95%, drying in the condition of 80-90 DEG C, and doing sinter process in the condition of 170-190 DEG C. The naturally colorful cotton fabric reaches the easy-care trimming effect in the boiled-free or boiled condition owing to adopting the heating nip-dip and the penetration humectant for accelerating the penetration of the finishing agent.

Description

technical field [0001] The invention relates to the treatment of fabrics, in particular to an ecological non-ironing finishing method for natural colored cotton fabrics. Background technique [0002] Natural colored cotton is a new generation of green and environmentally friendly fiber, and it is a successful example of modern high-tech methods in fiber development and production. At present, the textile products of natural colored cotton mainly have two forms of pure spinning and blended yarns, and on the basis of the basic forms of these two natural colored cotton yarns, the development of corresponding colored cotton products, organic weaving, knitting and non-woven And other forms of fabric products. [0003] According to the forecast of the International Organic Agriculture Committee, in the next 50 years, 30% of the world's total cotton will be replaced by colored cotton. Natural colored cotton textiles will be one of the most competitive leading products in the inte...
