A dyeing and finishing method suitable for cotton embroidered cloth or cotton voile

Abstract

The invention discloses a method for dyeing and finishing cotton embroidered cloth or cotton voile, which comprises the steps of singeing the embroidered cotton cloth or voile with white base → boiling and bleaching in a long car → mercerizing → dyeing → oiling and setting the shape For processing, in the process of long car cooking and bleaching, according to tea saponin 28‑32g / L, octylphenol polyoxyethylene ether OPE3‑5g / L, N, N‑oleoyl bis taurate sodium 4‑6g / L is added to the treatment liquid in the long car hopper, and the temperature of the treatment liquid is controlled at 98°C, the speed of the car is 40 m / min, and the stacking time is 40 minutes. The invention only performs one treatment on the long car, improves the utilization rate of the equipment, reduces the damage to the gray cloth at the same time, and reduces the consumption of water, electricity and steam by 50%.

Description

technical field [0001] The invention relates to the technical field of dyeing and finishing, in particular to a dyeing and finishing method suitable for cotton embroidered cloth or cotton voile. Background technique [0002] Cotton embroidered cloth and cotton voile are common clothing fabrics. For cotton fabrics, the general dyeing and finishing process is: white billet delivery → white billet singeing → long car desizing → long car oxygen bleaching → mercerizing → Dyeing → Oiling and setting. In the traditional technological process, two processes need to be done on the long car, that is, long car desizing and long car oxygen bleaching. The disadvantages are: first, due to the secondary process in the long car, the selvedge of the gray cloth It is very easy to be damaged, so that the cloth is often torn in the mercerizing process; second, the strength of the gray cloth will be significantly reduced when hydrogen peroxide is used for oxygen bleaching on the long car; third...

AI Technical Summary

Problems solved by technology

In the traditional process, two processes need to be done on the long car, that is, long car desizing and long car oxygen bleaching. The disadvantages are: first, because of the secondary process in the long car, the selvedge of the gray cloth It is very easy to be damaged, so that the cloth is often torn in the mercerizing process; second, the strength of the gray cloth will be significantly reduced when hydrogen peroxide is used for oxygen bleaching on the long car; third, the secondary production process on the same production equipment reduces the Production utilization of equipment increases energy consumption

[0003] If the production auxiliaries used in the two production processes of long-car desizing and long-car oxygen bleaching are combined into one process for production, the gray cloth of all-cotton embroidery cloth and all-cotton voile will be stained with gray cloth during weaving. Rust, iron filings, etc. contain iron impurities, but the iron impurities have not been cleaned in the desizing process. If the iron impurities are cleaned from the gray fabric, they will directly oxidize with the auxiliary agent hydrogen peroxide, which will cause many small spots on the surface of the gray fabric. hole
