Problems solved by technology

[0003] To achieve the color effect of hemp gray, the traditional method is yarn-dyed weaving, that is, using yarn-dyed yarn to weave fabrics, but the cost of yarn-dyed weaving is high and requires a large batch, which cannot meet Small batch requirements
Then there is the step-by-step dyeing of fabrics containing two or more fibers using the two-bath or multi-bath method, which is time-consuming and expensive to process

Embodiment 1

[0037] Fabric 75D / 72F (polyester + polypropylene) cotton wool

[0038] 1. Pretreatment: Synthetic fiber degreasing agent 2g / L, treated at 90°C for 20 minutes.

[0039] 2. Dyeing: Keep the water temperature at 40°C, add 0.5% (o.w.f) of disperse dye, 1% of leveling agent, add glacial acetic acid to adjust the pH value of the dyeing bath to 4.5, and start to heat up after the dyeing bath runs evenly, at a rate of 2°C / min The temperature was raised to 60°C at a rate, then to 100°C at a rate of 1°C / min, and finally to 120°C at a rate of 1.5°C / min, and kept for 40 minutes.

[0040] 3. Post-treatment: non-ionic detergent 1.5g / L, 15 minutes at 60°C.

Embodiment 2

[0042] Fabric 75D / 72F (polyester + polypropylene) waffle

[0043] 1. Pretreatment: Synthetic fiber degreasing agent 2g / L, treated at 90°C for 20 minutes.

[0044] 2. Dyeing: Keep the water temperature at 40°C, add 1.5% (o.w.f) of disperse dyes, 0.5% of leveling agent, add glacial acetic acid to adjust the pH value of the dyeing bath to 4.5, and start to heat up after the dyeing bath runs evenly, at a rate of 2°C / min The temperature was raised to 60°C at a rate of 1°C / min, then to 100°C at a rate of 1°C / min, and finally to 130°C at a rate of 1.5°C / min, and kept for 40 minutes.

[0045] 3. Post-treatment: Soda ash 3g / L, hydrosulfite 2g / L, 15 minutes at 80°C.

Abstract

The invention discloses a dissimilation pattern structure of dacron and polypropylene fiber blended fabric and a dyeing method thereof. The structure comprises a unit pattern structure and is characterized in that each unit pattern is composed of four unit pattern widths arranged vertically. Each unit pattern width is composed of a triangle and a straight line. The method sequentially includes adopting synthesis fiber degreaser to remove oil stains in dacron and polypropylene fiber, controlling temperature and pH to conduct dyeing, and adopting nonionic detergent or soda ash and sodium hydrosulfite to conduct post-processing. The dissimilation pattern structure and the dyeing method are methods for designing novel patterns of the dacron and the polypropylene fiber and achieving dyeing of pattern color differentiation and post-processing. The color differentiation of the pattern can be achieved through one-step dyeing, and a color differentiation effect is easy to control.

Description

technical field [0001] The invention relates to a pattern improvement of a polyester and polypropylene blended fabric and a dyeing method thereof, in particular to a dyeing method of an alienated pattern structure of a polyester and polypropylene blended fabric, belonging to the technical field of textiles. Background technique [0002] The blended fabric of polyester and polypropylene is a necessity for clothing life, which makes up for the deficiency of pure polyester or nylon fabric and plays a better use function. Dyeing and post-treatment on the surface of its fabrics to achieve differential dyeing effects on polyester and polypropylene blended fabrics is the focus of the process. [0003] To achieve the color effect of hemp gray, the traditional method is yarn-dyed weaving, that is, weaving fabrics with dyed yarns, but the cost of yarn-dyed weaving is relatively high and requires a large batch, which cannot meet the requirements of small batches. Then there is the st...
