Dyeing and finishing method suitable for all-cotton embroidery fabric or all-cotton voile

Abstract

The invention discloses a dyeing and finishing method for all-cotton embroidery fabric or all-cotton voile. The all-cotton embroidery fabric or all-cotton voile is processed through the procedures of white blank singeing, long spinning vehicle scouring and bleaching, mercerizing, dyeing and oiling shaping in sequence, wherein during the long spinning vehicle scouring and bleaching process, 28-32 g/L of tea saponin, 3-5 g/L of OPE (Octylphenol Polyoxyethylene Ether), and 4-6 g/L of N, N-sodium oleoyl di-taurinate into the treating liquid of a long spinning vehicle material groove; the treating liquid temperature is controlled to be 98 DEG C, the vehicle speed is controlled to be 40 meter/minutes, and the piling heat preservation time is controlled to be 40 minutes. According to the invention, only one-time processing is implemented on the long spinning vehicle, the equipment utilization ratio is increased, the damage to gray fabric is reduced, and the water, electricity and steam consumption is reduced 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
