Embodiment 1

[0021] Selection of raw material refining enzymes:

[0022] The performance of refining enzyme directly affects the quality of pre-treatment semi-finished products, such as: hair effect, whiteness, strength, grammage, cloth surface effect, and indirectly affects the vividness, color yield, and color fastness of dyed and printed products. Uniformity of cloth surface. Therefore, the selection of scouring enzyme must consider its permeability, emulsification, chelating power, dispersing power, H 2 o 2 stability.

[0023] Permeability: The canvas sedimentation method is used for detection, and it is required to be within 10S to ensure that the liquid-carrying rate of the fabric after immersion is 80-100%;

[0024] Emulsification: The level of emulsification directly affects the level of fabric wool effect and the uniform dyeing property of the cloth surface, and the emulsification power of paraffin wax, spindle oil and machine oil is evaluated respectively;

[0025] Chelating ...

Embodiment 2

[0051] The polyester-cotton fabric adopts the pretreatment method of high-efficiency refining enzyme step-one-bath method. The following working solution is used to heat up the chemical material at 55°C, and then the dry cloth of the fabric to be treated is sent into the working solution for padding. 100%, then steamed at a high temperature of 98°C for 75 minutes, then washed with hot water above 98°C and washed twice with water at 65°C, and then dried to complete the one-step-one-bath pretreatment. The specific ratio of the working fluid is:

[0052] Hydrogen peroxide (100%) 12 g / L;

[0053] High-efficiency refining enzyme 28 g / L;

[0054] Refined penetrant 6 g / l.

[0055] Dye the fabric pre-treated by SX-85 high-efficiency refining enzyme one-step new process, and compare the physical performance indicators of the fabric with the products of the traditional pre-treatment process.

Embodiment 3

[0057]The polyester-cotton fabric adopts the pretreatment method of high-efficiency refining enzyme step-one-bath method. The following working solution is used to heat up the chemical material at 60°C, and then the dry cloth of the fabric to be treated is sent into the working solution for padding. 80%, then steamed at a high temperature of 102°C for 70 minutes, then washed with hot water above 96°C and washed twice with water at 60°C, and then dried to complete the one-step-one-bath pretreatment. The specific ratio of the working fluid is:

[0058] Hydrogen peroxide (100%) 14 g / L;

[0059] High-efficiency refining enzyme 26 g / L;

[0060] Refined penetrant 8 g / l.

[0061] The fabrics pre-treated by SX-85 high-efficiency refining enzyme one-step new process were printed, and the physical performance indicators of the fabrics were compared with the products of traditional pre-treatment processes.

[0062] Embodiment 2-3 gained product and traditional product comparison data ...

Abstract

The invention relates to a manufacturing method of fabrics. Highly active refined enzyme one-step-one-bath preprocessing method is adopted for a polyester-cotton fabric, the method has the following steps: following solutions are adopted, a chemical of 50-60 DEG C is heated up, a piece of dry fabric cloth to be processed is sent to working solutions for padding with dispersed phase holdup of 80-100%, then the dry fabric cloth is steamed for 60-75 min under the temperature of 98-102 DEG C, dried after being washed by hot water under the temperature of 95 DEG C to 98 DEG C at first and then by water under the temperature of 60 DEG C to 65 DEG C, thus the one-step-one-bath preprocessing method is competed. The working solutions used in the method has mixture ratio as follows: hydrogen peroxide (100%) 12-14 gram / liter; highly active refined enzyme 25-30 gram / liter; refined osmotic agent 5-8 gram / liter. The highly active refined enzyme preprocessing method combines refining, stabilizing, infiltrating, emulsificating, chelating into a whole, hydrogen peroxide stabilizer and alkali and the like are not needed to be added, thus ensuring stability and uniformity of preprocessing, not only saving sewage treatment expense but also reducing sewage treatment pressure.

Description

1. Technical field: [0001] The invention relates to a fabric production method, in particular to a pretreatment method for polyester-cotton fabrics. 2. Background technology: [0002] According to the "Eleventh Five-Year" development outline of the textile industry, by the end of the "Eleventh Five-Year Plan", my country's textile printing and dyeing industry will reduce energy consumption and environmental protection by 10% compared with 2005. The annual reduction is 20%, and the sewage discharge per unit output value is 22% lower than that in 2005. As we all know, the printing and dyeing industry has always been one of the largest users of water consumption and sewage discharge. The textile industry's sewage discharge accounts for 35% of the total industrial wastewater, and the printing and dyeing industry's wastewater accounts for 80% of the national textile wastewater discharge, and the average reuse rate is only 10%. At present, the water consumption per unit product o...
