Embodiment Construction

[0019] A wet-wet short-flow pretreatment process for fabrics, characterized in that: the following steps are carried out in sequence:

[0020] Firstly, the gray cloth of 27.8tex*27.8tex pure ramie plain cloth after singeing treatment is scoured, the amount of NaOH is 30-35g / l, the amount of self-made penetrating agent is 3.5g / l, and the steaming temperature is 100±1 ℃; steaming time is 55min;

[0021] Secondly, after the scouring treatment, the gray cloth is washed with water and then bleached with chlorine. The amount of sodium chlorite in the bleach solution is 6g / l, the pH value is adjusted to 10.5, and it is stacked at 20°C for 45 minutes;

[0022] Again, carry out oxygen bleaching treatment after the gray cloth after chlorine bleaching treatment is dechlorinated, pickling, the H in the oxygen bleaching liquid 2 o 2 The dosage is 4.0g / l, the stabilizer is 2.0g / l, the water glass is 3.5g / l, the homemade penetrant M3.5g / l, the pH value is adjusted to 10.5, the steaming tem...

Abstract

The invention discloses a wet and short flow-process pretreatment process of fabric, firstly, boiling-off treatment of the gray fabric is conducted, after that, the gray fabric is washed with water, then, chlorine bleaching treatment is conducted, and then, dechlorination, acid washing of the gray fabric are conducted, lastly, oxygen bleaching treatment is conducted; the components of the oxygen bleaching solution is are follows: H2O2 of 4.0g / l, stabilizer of 2.0g / l, water glass of 3.5g / l, self-made penetrant of 3.5g / l, and pH value of 10.5; the gray fabric which experiences the oxygen bleaching treatment is washed by water, and then is directly mercerized, so as to obtain the finished fabric; the alkali-liquid concentration in the mercerizing liquid is of 160g/l, the self-made penetrant is of 5.0g/l, the speed of vehicle is of 65m/min, and the cloth-surface expander tension is 95% of the gray fabric width; the self-made penetrant is phosphoric-acid composite ester type anionic surfactant; the stabilizer is organic multi-phosphate. The invention fills the gap in study on the self-penetrant, realizes the reform for the high-energy-consumption, high-emission, and low-efficiency pretreatment production process, reduces the energy consumption, and decreases the pressure of resources and environmental-protection.

Description

Technical field: [0001] The invention mainly relates to the pretreatment of ramie fabrics and blended fabrics thereof, in particular to a wet-wet short-flow pretreatment process of fabrics. Background technique: [0002] In the prior art, the pretreatment of ramie fabric and its blended fabric is to carry out scouring, chlorine bleaching, oxygen bleaching treatment on the gray cloth, after the drying process, and then through the mercerizing process. Due to the intermediate drying process, the gray cloth processing process has the disadvantages of high energy consumption, high emission and low efficiency. Invention content: [0003] The object of the present invention is to make up for the defects of the prior art, and provide a short wet-wet pretreatment process for fabrics, which can realize the effect of energy saving and emission reduction. [0004] The present invention is achieved through the following technical solutions: [0005] A wet-wet short-flow pretreatment...
