Problems solved by technology

[0002] In the printing and dyeing process of fabrics, the pre-treatment of natural cellulose fibers (also known as plant fibers, including cotton and hemp) is the process with the largest amount of water, energy consumption and high-pollution wastewater. This is due to the traditional pre-treatment Most of the processes use caustic soda to remove impurities from natural cellulose fiber fabrics, and the extensive use of caustic soda has caused "three highs" problems (high energy consumption, high water consumption, high COD value of wastewater)

Embodiment 1

[0015] Example 1: The specific processing process of organic mineral pretreatment of white and light-colored cotton knitted fabrics is as follows: control the weight bath ratio of cotton knitted gray fabric and water to 1:8, adjust the pH value to 6.5-7.5, and raise the temperature to 55°C , then add neutral pectate lyase EcoScour 0.25% (o.w.f) and neutral cellulase MAX 0.4% (o.w.f) to the water successively, add organic substitute base MC-625 2g / L after incubation for 60min, and adjust the pH value From 10 to 11, add environmental-friendly multifunctional mineral pretreatment agent NOVECO 1.5g / L, low-temperature scouring and bleaching agent Mianlijing LTB-01 2g / L, hydrogen peroxide (27%) 10g / L, and heat up to 80°C , keep warm for 45 minutes, drain water, and finally wash with deoxygenated water to complete the organic and mineral pretreatment of white and light-colored cotton knitted fabrics.

Embodiment 2

[0016] Example 2: The specific processing process of the organic mineral pretreatment of medium-dark cotton knitted fabrics is as follows: control the weight-to-bath ratio of cotton knitted gray fabric and water to 1:9, adjust the pH value to 6.5-7.5, and raise the temperature to 55 ℃, then add neutral pectate lyase EcoScour 0.24% (o.w.f) and neutral cellulase MAX 0.45% (o.w.f) to the water successively, add organic substitute base MC-625 2.6g / L after incubation for 70min, adjust When the pH value reaches 10-11, add environmental-friendly multifunctional mineral pretreatment agent NOVECO 2g / L, low-temperature scouring and bleaching agent Mianlijing LTB-01 2.6g / L, hydrogen peroxide (27%) 9g / L, and heat up to 80°C, keep warm for 45 minutes, drain water, and finally deoxygenate and wash water to complete the organic mineral pre-treatment of medium-dark cotton knitted fabrics.

Embodiment 3

[0017] Example 3: The specific processing process of the organic mineral pretreatment of the whole hemp knitted fabric is as follows: control the weight-to-bath ratio of the whole hemp knitted gray fabric and water to 1:10, adjust the pH value to 6.5-7.5, and raise the temperature to 55°C. Then add neutral pectate lyase EcoScour 0.3% (o.w.f) and neutral cellulase MAX 0.6% (o.w.f) to the water successively, add organic substitute base MC-625 3g / L after incubation for 65min, adjust the pH value to From 10 to 11, add environmental-friendly multifunctional mineral pretreatment agent NOVECO 2.5g / L, low-temperature scouring and bleaching agent Mianlijing LTB-01 3g / L, hydrogen peroxide (27%) 12g / L, and heat up to 85°C. Drain after 50 minutes of heat preservation, and finally deoxygenate and wash with water to complete the organic mineral pretreatment of all hemp knitted fabrics.

Abstract

The invention discloses an organic mineral pre-treatment method of a natural cellulose fiber knitted fabric. The organic mineral pre-treatment method is characterized in that low-temperature refining and polishing synchronous treatment is carried out on the natural cellulose fiber knitted fabric, and then low-temperature composite treatment is carried out through multifunctional mineral substances and a scouring and bleaching activating agent. The organic mineral pre-treatment method has the advantages that the low-temperature refining and polishing synchronous treatment is carried out on the natural cellulose fiber knitted fabric and the low-temperature composite treatment is carried out through the multifunctional mineral substances and the scouring and bleaching activating agent, so that organic mineral pre-treatment of all the natural cellulose fiber knitted fabrics can be realized; the organic mineral pre-treatment method has a wide applicable object range and can be produced in a large batch; a whole treatment process has the advantages of energy saving and high efficiency, greenness and environmental protection.

Description

technical field [0001] The invention relates to the processing of natural cellulose fiber knitted fabrics in the textile field, in particular to an organic mineral pretreatment method for natural cellulose fiber knitted fabrics. Background technique [0002] In the printing and dyeing process of fabrics, the pre-treatment of natural cellulose fibers (also known as plant fibers, including cotton and hemp) is the process with the largest amount of water, energy consumption and high-pollution wastewater. This is due to the traditional pre-treatment Most of the processes use caustic soda to remove impurities from natural cellulose fiber fabrics, and the extensive use of caustic soda has caused "three highs" problems (high energy consumption, high water consumption, and high COD value of wastewater). Today, as environmental protection issues are becoming more and more serious, countries have put forward very stringent specifications for textiles and textile auxiliaries, which mak...
