Low-temperature pre-treatment technology of cotton fabric

The invention relates to a low-temperature pre-treatment technology of a cotton fabric. The low-temperature pre-treatment technology is characterized in that the cotton fabric is sequentially subjected to work procedures of hot water pre-treatment, biological enzyme treatment, hot water washing, enzyme inactivation and water washing, and then the cotton fabric is treated in a treating bath by a low-temperature scouring-bleaching agent, a low-temperature scouring-bleaching accelerant, a low-temperature hydrogen peroxide activator, and hydrogen peroxide. The low-temperature pre-treatment technology has a short process and moderate reaction conditions, adopts the raw materials with low cost, and has an environment-friendly effect due to low values of COD (Chemical Oxygen Demand) and AOX (Adsorbable Organic Halides) in waste water; besides, the treated cotton fabric is good in whiteness, capillary effect and breaking strength and symbionts in the cotton fabric can be effectively removed. The low-temperature pre-treatment technology only has little damage to fibers and the treated cotton fabric has a good scouring effect, and is high in quality and soft in handfeel; the energy consumption of printing and dyeing is lowered greatly and the energy consumption of water, electricity and gas is far lower than that of a traditional technology, so that the low-temperature pre-treatment technology is very beneficial to protection of biological environment and greatly reduces pressure of environment protection, energy conservation and emission reduction.

Spinning and dyeing pretreatment auxiliary agent and preparation method and application thereof

The invention relates to a spinning and dyeing pretreatment auxiliary agent, which is prepared by adopting the following raw material components: 30 to 50 parts by weight of desizing agent, 5 to 20 parts by weight of alkali-resisting penetrant, and 4 to 10 parts by weight of complexing agent; the desizing agent is multi-alkyl amine salt; the alkali-resisting penetrant is an alkali-resisting nonionic surfactant; the complexing agent is hydroxy carboxylate. Further, the adopted raw material components also include 1 to 10 parts by weight of hydrogen peroxide stabilizer; the hydrogen peroxide stabilizer is organic phosphonate. The spinning and dyeing pretreatment auxiliary agent can be obtained through the preparation of successively mixing the raw material components, and the spinning and dyeing pretreatment auxiliary agent can be applied to a cold-batch method or open-width scouring-bleaching method spinning and dyeing pretreatment process. The spinning and dyeing pretreatment auxiliary agent can shorten the flow of the conventional spinning and dyeing pretreatment process, can reduce the energy consumption and material consumption in the pretreatment process, and can reduce the effluent volume; an obtained intermediate product of textile fabrics has good whiteness, capillary effect and desizing percentage.
