Embodiment 1

[0015] A bamboo / cotton blended knitted fabric dyeing and finishing process, including the following process steps: gray fabric manufacturing, the raw material of the gray fabric is 32s50 / 50 bamboo pulp / cotton and 30D stretch cloth; where the 32s50 / 50 bamboo pulp / cotton is: 32 fibers, bamboo Pulp and cotton are each 50%. After inspection of the grey fabric, in order to eliminate the internal stress of the fabric during the manufacturing process and avoid the wrinkles in the dyeing and finishing process, the fabric is cut and shaped, and the Fuchsia Monfuji setting machine (10 boxes) is used. The temperature of the cutting and shaping process is 195℃, and the speed is 40M / min; then in order to ensure that the front is smooth, free from scratches, and stains, stitch the front inward. Secondly, scouring and bleaching, the whiteness of bamboo fiber is yellower than cotton fiber due to the existence of natural pigments. If bamboo fiber is blended with cotton, the whiteness and wool e...

Abstract

The invention discloses a bamboo / cotton blended knitted fabric dyeing and finishing process, which comprises the following steps: manufacturing blank fabric; detecting the blank fabric; slitting and forming; finishing the fabric inward from the front side and combining; boiling and blanching; polishing; dyeing; drying; padding moisture-absorbing and quick-drying assistant for finishing; and obtaining finished product. In the polishing process, polishing enzyme and glacial acetic acid are used as finishing agent, the polishing is performed at 55 DEG C for 50 minutes, and the pH value of the polishing solution is 4.5 to 5.5; in the dyeing process, the temperature is 60 DEG C, and the dye is Argazol red BF-3B, Argazol yellow BF-3R and Argazol red navy BF-RRN; and the finishing agent is anhydrous sodium sulphate and used for replacing KS and soaping agent. The process overcomes the drawbacks of low wet strength, low alkali resistance, deformation and pilling of bamboo fiber fabrics.

Description

Technical field [0001] The invention relates to a dyeing and finishing process for a bamboo / cotton blended knitted fabric. Background technique [0002] At present, the development trend of clothing is mainly manifested as natural, green, safe and environmentally friendly, comfortable and healthy. The durable anti-inflammatory and antibacterial effects of bamboo fiber, moisture absorption, breathability, freshness and coolness, health care and skin care, and green environmental protection functions just meet people's needs and are deeply favored by people. Mainly manifested as: (1) Soft and smooth: Bamboo fiber is soft and smooth without sticking to the body. It is softer than cotton and has a unique velvet feel. It is a well-deserved fabric of choice for textiles. (2) Absorbing sweat and wicking moisture: The cross-section of bamboo fiber is covered with large and small oval pores, which can absorb and evaporate a large amount of water in an instant. The water absorption of bam...
