Abstract

The invention discloses a bleaching working fluid of the flax fabric or flax/cotton fabric and a low-temperature bleaching technology using the working fluid. One formula of the bleaching working fluid is as follows: each liter of the working fluid comprises the following ingredients: 1-20g/L of H2O2 with the concentration of 30 percent, activating agent TAED (Tetra Acetyl Ethylene Diamine) with the mol ratio of 1/15:1-1:1 with the H2O2, 0.1-10g/L of stabilizing agent, 0.1-5g/L of penetrating agent and the rest is water. The low-temperature bleaching technology adopting the bleaching working fluid formula is the bleaching technology in low-temperature bath. Another formula of the bleaching working fluid is as follows: each liter of the fluid comprises 10-50g/L of H2O2 with the concentration of 30 percent, activating agent TAED (Tetra Acetyl Ethylene Diamine) with the mol ratio of 1/15:1-1:1 with the H2O2, 0.1-10g of stabilizing agent and the rest is water. The low-temperature bleaching technology adopting the bleaching working fluid formula is cold pad-batch bleaching technology. The invention adopts the TAED as the activating agent, introduces oxydol/TAED bleaching system, has better bleaching effect, can reduce the damage of the fabrics and improves the production efficiency.

Description

technical field [0001] The invention relates to a textile pretreatment process, in particular to a flax, linen / cotton fabric bleaching working liquid and a low-temperature bleaching process using the working liquid. Background technique [0002] Flax is an important raw material for the hemp textile industry, and its fibers are strong and soft. Flax fiber is strong, not easy to rot in water, and has waterproof effect. In addition, it has unique advantages such as friction resistance, high temperature resistance, fast heat dissipation, poor dust adsorption, not easy to tear, not easy to burn, no static electricity, etc. It is green and environmentally friendly. important textile raw materials. Linen yarn can be machine-woven into all kinds of high-grade clothing fabrics, clothing and socks fabrics, denim fabrics, etc. The fabrics are smooth and tidy, natural and crisp, elegant and high-end, suitable for making high-end clothing materials, especially summer clothing, with goo...
