The complete fabric of decatize is washed through rinsing bowl；
Four), dry
Three road master operation desizing of traditional cotton pretreatment, kiering, bleaching are typically carried out step by step, but this three
Procedure is not completely unrelated, but influences each other, is complementary to one another.As also there being removal part natural impurity while desizing
Effect, can mitigate kiering has functions that to remove residual slurry further, and fabric whiteness is also improved, and bleaching also has further impurity elimination
Effect.Conventional three-step approach pre-treating technology is safe, favorable reproducibility, but board is many, and the time is long, and efficiency is low, high energy consumption；Additionally,
Need to consume substantial amounts of water, heat energy, chemical assistant in traditional bafta boiling and bleaching process process, give off and contain high concentration dirt in a large number
The waste water of dye thing.Therefore, shortened process, simplified process equipment, few energy-saving new technology of scouringing and bleaching that discharges pollutants are replaced
Generation traditional alkali oxygen technique is the inevitable direction of cotton pretreatment development.

Ion chelate complex is stablized it is easy to sedimentation, so that hydrogen peroxide uniform decomposition, prevents metal ion catalysis hydrogen peroxide excessive decomposition from causing
Fabric broken hole；Carboxyl in strand ,-CS2 -Group acts synergistically, and enhances chelate effect.Sulfonic group in strand, carboxylic
Base ,-CS2 -Constitute the hydrophilic segment of strand, butyl acrylate constitutes hydrophobic part, thus forming hydrophilic, oleophylic emulsification, dividing
Scattered performance, due to the molecular weight of polymer larger it is thus possible to preferably the impurity coming off on bafta is carried out emulsifying, point
Dissipate.
Under the long-time condition of high temperature, the slurry of cloth cover can expand, and cotton seed hulls comes off, Tea Saponin by slurry degradation,
And with the collaborative commensals removing oil removing wax, ash content, impurity and other cotton fibers such as fatty acid methyl ester ethoxylate sulfonate, double
Oxygen water, by the pigment oxidation of cotton fiber, bleaches cloth cover, completes the pre-treatment of polyester-cotton fabric after the physics of some row, chemical reaction
Journey.
