Description

With the disposable fabric of finishing destarch and refining of biology enzyme

Technical field

The present invention relates to a kind of method of fabric desizing, especially utilize the disposable method of finishing fabric desizing and refining of biology enzyme.

Background technology

The traditional handicraft of high temperature highly basic is generally adopted in the pre-treatment of COTTON FABRIC, not only working condition is abominable, and discharge a large amount of strong basicity waste water, influence ecological environment and health, simultaneously destarch and refining will be divided into for two steps and finish in the traditional handicraft, a large amount of waste water resources, the requirement of not compound " green " and energy-saving and emission-reduction.

Summary of the invention

The purpose of this invention is to provide a kind of efficiently, the processing method of environment-friendly type fabric desizing and refining cheaply, the method for especially carrying out fabric desizing and refining with biology enzyme.

For realizing that technical scheme provided by the present invention is:

A kind of disposable method of finishing fabric desizing and refining of biology enzyme of utilizing, it is characterized in that with native starch or converted starch, or starch and PVA are the fabric of starching main body altogether, the technology that adopts is as follows: fabric → dipping hot water → maceration enzyme liquid (rolls 60 ℃ of enzyme temperature, 55 ℃ of the temperature of banking up, time 1h, pH7.0, NaCL 5g/L, JFC 1g/L; bath raio 1: 25) → insulation banks up → maceration enzyme liquid (pectase 4g/L-12g/L; penetrating agent JFC 2g/L, pH 7-10,50 ℃-60 ℃ of temperature; time 60min-90min, bath raio 1: 25) → make enzyme deactivation (boiling water boils 2min) → hot water wash (60 ℃-70 ℃) → cold wash → dry.

This method utilizes biology enzyme to handle, mild condition, technological process is short, equipment is simple, and energy consumes little, and sewage is few, can effectively avoid fiber impaired in the processing procedure, the fluffy softness of fabric feeling after biology enzyme is handled can improve the added value of COTTON FABRIC, makes product to variation, functionalization and superior development.

The specific embodiment

In the actual production, with native starch or converted starch, or starch and PVA are the fabric of starching main body altogether, the technology that adopts is as follows: fabric → dipping hot water → maceration enzyme liquid (rolls 60 ℃ of enzyme temperature, 55 ℃ of the temperature of banking up, time 1h, pH7.0, NaCL 5g/L, JFC 1g/L; bath raio 1: 25) → insulation banks up → maceration enzyme liquid (pectase 4g/L-12g/L; penetrating agent JFC 2g/L, pH 7-10,50 ℃-60 ℃ of temperature; time 60min-90min, bath raio 1: 25) → make enzyme deactivation (boiling water boils 2min) → hot water wash (60 ℃-70 ℃) → cold wash → dry.

Preparation method of the present invention is following steps:

1., textile impregnation enzyme liquid (is rolled 60 ℃ of enzyme temperature, 55 ℃ of the temperature of banking up, pH7.0, NaCL 5g/L, JFC 1g/L; bath raio 1: 25) insulation is banked up, the time 30-60min that banks up, and proceeding to preferably to the slurry destarch of fabric outer with enzyme, length is standard; the biology enzyme of destarch can be selected hay bacillus amylase (α-Dian Fenmei) for use; HIC destarch enzyme, diastase (beta amylase), amylopsin etc.;

2., will bank up textile impregnation enzyme liquid (the pectase 4g/L-12g/L of a period of time, penetrating agent JFC 2g/L, pH 7-10,50 ℃-60 ℃ of temperature, time 60min-90min), destarch and refining are carried out with same body lotion, are about to pectase liquid and join the body lotion that destarch is before used, in order to keep bath raio 1: 25, can suitably increase the content of water;

3., boiling water boils 2min, and biology enzyme is lost activity, and stops destarch and refining, hot water wash (60 ℃-70 ℃) rapidly, cold wash twice is dried;

Below in conjunction with embodiment content of the present invention is described further:

Embodiment one

Batching: native starch, PVA;

The preparation method:

1., textile impregnation enzyme liquid (is rolled 60 ℃ of enzyme temperature, 55 ℃ of the temperature of banking up, pH7.0, NaCL 5g/L, JFC 1g/L; bath raio 1: 25) insulation is banked up, the time 30-60min that banks up, and proceeding to preferably to the slurry destarch of fabric outer with enzyme, length is standard; the biology enzyme of destarch can be selected hay bacillus amylase (α-Dian Fenmei) for use; HIC destarch enzyme, diastase (beta amylase), amylopsin etc.;

2., will bank up textile impregnation enzyme liquid (the pectase 4g/L-12g/L of a period of time, penetrating agent JFC 2g/L, pH 7-10,50 ℃-60 ℃ of temperature, time 60min-90min), destarch and refining are carried out with same body lotion, are about to pectase liquid and join the body lotion that destarch is before used, in order to keep bath raio 1: 25, can suitably increase the content of water;
