Embodiment 1

[0045] The first step: pretreatment process

[0046] 1. Desizing process:

[0047] Put the cupro ammonia fiber in the normal temperature winding machine, start to heat up at room temperature, raise the temperature to 40°C, add desizing enzyme 2g / L and run for 10 minutes, add penetrant 1g / L, heat up to 80°C and run for 20 minutes to reach the bath The ratio is 1:20.

[0048] 2. Bleaching process

[0049] Drain the remaining desizing aid and water in the packaging machine. The first step: add soda ash to adjust the pH value to 11, and stir for 20 minutes until uniform; the second step: add 30% hydrogen peroxide 6g / L. Raise the temperature to 40°C, stir for 10 minutes, the third step: add stabilizer 2g / L, stir for 5 minutes, until uniform; the fourth step: add detergent 1g / L, stir for 10 minutes, liquor ratio 1:20;

[0050] 3. Enzyme washing and polishing process by air machine

[0051] Add 1 g / L of cellulase, run for 5 minutes; adjust the pH value to 4.5 with buffer acid, run...

Abstract

The invention relates to a process for dyeing and finishing a fiber fabric, in particular to a process for dyeing and finishing a cuprammonuium fabric, which includes invert-sewing, prewashing, desizing, bleaching, enzymatic washing and polishing via an airflow dyeing machine, dyeing, setting and softening of rolling stock, AIRO finishing, tentering finishing and obtaining the finished product. According to the technical scheme, the process has the advantages that the traditional preprocessing technique is eliminated and replaced by the novel environment-friendly desizing, scouring and bleaching preprocessing technique using both sodium carbonate and hydrogen peroxide so that processing is complete while fabric functions are unspoiled, the fully slack dyeing and finishing process is adopted, and accordingly qualified fabric quality and internal indexes are guaranteed, and the best effect of the cuprammonuium fabric is achieved.

Description

technical field [0001] The invention relates to a processing technology for fiber fabrics, in particular to a dyeing and finishing process for cupro ammonia fiber fabrics. Background technique [0002] In recent years, various new fiber fabric products are more and more favored by consumers, new products continue to emerge, and the competition of special fiber fabric products in the market continues to intensify, and the processing technology of cupro ammonia fiber emerges as the times require. [0003] Cotton fibers in cupro fibers are generally combed cotton, with relatively few natural impurities, while cupro fibers only contain some oils applied during spinning, so the pretreatment can be done milder and less damaging to the cupro fibers. Small no-alkali or low-alkali processes. In addition, because cupro ammonia fiber is not alkali-resistant, it cannot be mercerized, and the color brightness, saturation and gloss of the product will be affected to a certain extent. ...
