Problems solved by technology

Silk fabrics are favored by consumers because of their elegant luster, light and elegant style, soft feel and excellent wearing comfort. However, due to the low elasticity of silk fibers, especially the low elastic recovery rate, ordinary silk fabrics are used The fabrics made are easy to wrinkle and difficult to restore to its original shape after wrinkling, and its wrinkle resistance is poor, which affects the consumption of real silk fabrics to a large extent

Embodiment 1

[0025] Step 1: Silk fabric pretreatment, experimental plan: silk fabric 10cm×10cm, 60°C, soap flakes 2g / L, NaHCO 3 5g / L, liquor ratio 1:50, boiled in water for 30min, and dried in vacuum at 60°C. Then use acetone, ethanol, and deionized water to wash with ultrasonic vibration, and ultrasonically wash each solution for 20 minutes. After washing, take out the cloth sample and dry it in vacuum at 60°C.

[0026] Step 2: Preparation of pyrimidine derivative dispersion emulsion method, experimental scheme: Add Span 20 (20% o.w.t) and Tween 80 (30% o.w.t) into 100 mL of water, and emulsify at a speed of 10000 rpm for 30 min. During this process, 10% (o.w.f) 2,4,6-trichloropyrimidine compound was slowly added to the solution. Water was then added to dilute the emulsion to obtain a 3 g / L solution. Finally, silicone defoamer, 2 g / L sodium sulfate (catalyst) and 6 g / L sodium bicarbonate were added to each diluent and stirred uniformly to prepare a uniform dispersion of the pyrimidine c...

[0029] Step 1: Silk fabric pretreatment, experimental plan: silk fabric 10cm×10cm, 60°C, soap flakes 2g / L, NaHCO 3 5g / L, liquor ratio 1:50, boiled in water for 30min, and dried in vacuum at 60°C. Then use acetone, ethanol, and deionized water to wash with ultrasonic vibration, and ultrasonically wash each solution for 20 minutes. After washing, take out the cloth sample and dry it in vacuum at 60°C.

[0030] Step 2: Preparation of pyrimidine derivative dispersion emulsion method, experimental scheme: Add Span 20 (20% o.w.t) and Tween 80 (30% o.w.t) into 100 mL of water, and emulsify at a speed of 10000 rpm for 30 min.

[0033] Step 1: Silk fabric pretreatment, experimental plan: silk fabric 10cm×10cm, 60°C, soap flakes 2g / L, NaHCO 3 5g / L, liquor ratio 1:50, boiled in water for 30min, and dried in vacuum at 60°C. Then use acetone, ethanol, and deionized water to wash with ultrasonic vibration, and ultrasonically wash each solution for 20 minutes. After washing, take out the cloth sample and dry it in vacuum at 60°C.

[0034] Step 2: Preparation of pyrimidine derivative dispersion emulsion method, experimental scheme: add Span 20 (20% o.w.t) and Tween 80 (30% o.w.t) into 100-150 mL of water, and emulsify at a speed of 10000 rpm for 30 minutes. During this process, 10% (o.w.f) 2,4,6-trichloropyrimidine was slowly added to the solution. Water was then added to dilute the emulsion to obtain a 3 g / L solution. Finally, silicone defoamer, 2 g / L sodium sulfate (catalyst) and 6 g / L sodium bicarbonate were added to each diluent and stirred uniformly to prepare a uniform dispersion of the pyrimidine co...

Abstract

The invention provides a method for preparing an anti-wrinkle real silk fabric, and belongs to the field of surface grafting modification of textiles. The method specifically comprises the steps that firstly, the real silk fabric is pretreated, pyrimidine derivatives are adopted to modify the real silk fabric, the pyrimidine derivatives are grafted to the real silk fabric, and the wet-state wrinkle resistance of the real silk fabric is improved; and in addition, the K / S value of the real silk fabric obtained after dyeing modification of the reactive dye is improved, it is indicated that the modified real silk fabric has good dyeing performance, and the dyeability of the cotton fabric can be improved.

Description

technical field [0001] The invention belongs to the technical field of preparation methods of functional textiles, and in particular relates to a method for preparing anti-wrinkle silk fabrics. Background technique [0002] Silk fabric generally refers to silk, including mulberry silk, tussah silk, castor silk, tapioca silk, etc. Silk fabrics are favored by consumers because of their elegant luster, light and elegant style, soft feel and excellent wearing comfort. However, due to the low elasticity of silk fibers, especially the low elastic recovery rate, ordinary silk fabrics are used The fabric made is more prone to wrinkling and difficult to restore to its original shape after wrinkling, and its wrinkle resistance is poor, which affects the consumption of real silk fabrics to a large extent. Improving the wrinkle resistance of silk fabrics is an important direction to increase its added value. [0003] There are two ways to improve the wrinkle resistance of fabrics. One...
