Abstract
A low-temperature bleaching working solution for pure cotton woven fabrics belongs to the technical field of after treatment of the pure cotton woven fabrics, and comprises Schiff base metal complex, peroxide and low-temperature controlled catalyst. The low-temperature bleaching working solution comprising the Schiff base metal complex, the peroxide, the low-temperature controlled catalyst and water only needs to be treated at 50 to 70 DEG C, thereby effectively reducing about 20 percent energy consumption as compared with the treatment process of an original high-temperature bleaching formula.
Description
Technical field
The invention belongs to finishing technique field behind the pure cotton woven fabric, particularly through after arrangement form the postfinishing process of rubber-like pure cotton woven fabric.
Background technology
When pure cotton woven fabric being carried out the back arrangement; Need earlier fabric to be bleached processing, just can dye then or stamp, because prior art is in bleaching process; Usually adopting hydrogen peroxide bleaching is high-temperature bleaching and the bleaching of cold rolling heap; The energy consumption that directly causes producing is high, and the sewage disposal burden is heavy, can not satisfy the demand of the management that enterprise's low energy consumption produces.
Summary of the invention
The object of the invention provides a kind of pure cotton woven fabric cold bleaching working solution of saving bleaching process process energy consumption that is beneficial to.
The present invention includes the controlled catalyst of schiff base metal complex, peroxide and low temperature.
The accounting of the controlled catalyst of said schiff base metal complex, peroxide and low temperature in said working solution is respectively 0.001 ~ 0.05 g/L, 3 ~ 30g/L and 0.1 ~ 5g/L.
Said schiff base metal complex is a sulfo group salicylidene ethylenediamine schiff bases copper complex.
Said peroxide is a hydrogen peroxide, or SODIUM PERCARBONATE, or in the sodium perborate any one.
The controlled catalyst of said low temperature is a tetraacetyl ethylene diamine, or the ninth of the ten Heavenly Stems acyloxy benzene sulfonic acid sodium salt, or in 6 (N, N, N Trimethylamine methylene) caproyl caprolactam p-methyl benzenesulfonic acid any one.
The present invention adopts the cold bleaching working solution of being made up of schiff base metal complex, peroxide, the controlled catalyst of low temperature and water, only needs under 50～70 ℃ of conditions, to handle, and the treatment process of high-temperature bleaching prescription more originally can effectively cut down the consumption of energy about 20%.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in the restriction scope of the present invention.Should be understood that in addition those skilled in the art can do various changes or modification to the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
One, the fabric after the preparation destarch:
(1) learns from else's experience to being that 40, broadwise are 45 pure cotton woven fabric 60g.
