Embodiment Construction

[0011] In the low-temperature pretreatment process of cotton fabrics of the present invention, the cotton fabrics are first subjected to hot water pretreatment, biological enzyme treatment, hot water washing and enzyme inactivation, and water washing processes in sequence, and then low-temperature scouring and bleaching agents, low-temperature scouring and bleaching accelerators, and low-temperature hydrogen peroxide are used. Cotton fabrics are treated with activator and hydrogen peroxide in a treatment bath;

[0012] Hot water pretreatment consists of two hot water treatments and one warm water treatment in sequence, the temperature of hot water is 90-120°C, and the temperature of warm water is 50-70°C;

[0013] The biological enzyme treatment is to pad the enzyme desizing solution first, and then perform low-temperature steaming. The enzyme desizing solution is composed of 2-5g / L low-temperature desizing enzyme TF-162A and 2-4g / L non-ionic penetrant. The pH of the enzyme des...

Abstract

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.

Description

technical field [0001] The invention relates to a low-temperature pretreatment process for cotton fabrics. Background technique [0002] The purpose of cotton fabric pretreatment is to remove oil, size and natural impurities such as cotton wax on the fabric, so as to reduce the impurity content on the fabric and improve the water absorption and whiteness of the fabric. However, whether it is the three-step method of deboiling, boiling and bleaching, or the two-step method of deboiling, bleaching or one-step decoiling and bleaching, corresponding additives must be used to ensure the quality of deboiling and bleaching. The scouring agent should have excellent permeability, emulsification and dispersibility. During the scouring process, the penetrability of the scouring agent enables it to quickly and evenly penetrate into the interior of the fabric, yarn and fiber, so that the fiber is fully hydrated; the emulsifying property enables it to remove the waxy substances, oils and...
