Embodiment 1

[0037] (1) Pretreatment of regenerated cellulose fabric: soak regenerated cellulose fabric in the pretreatment solution, the concentration of each component in the treatment solution is: soda ash 2g / L, penetrant JFC 0.5g / L, water balance; , the temperature is 90° C., and the time is 10 minutes; and then the fabric is subjected to anti-shrinkage treatment so that the moisture content of the fabric is 80%.

[0038] (2) Preparation of anti-yellowing finishing agent solution: the anti-yellowing finishing agent (the mass ratio of phenolic oxidant and phosphite is 6:1, the quality of polyether emulsifier is 0.2% of the quality of anti-yellowing finishing agent solution), penetrating agent Mix with water in an appropriate ratio (anti-yellowing finishing agent: 3%), penetrating agent JFC 2g / L, pH=about 5.0 (adjusted by citric acid, balance of water), and then mix the solution evenly under the agitator for later use , the stirring rate is 200rpm and the time is 10min, wherein the phosp...

Embodiment 2

[0045] According to embodiment 1, step (1)-step (4) is the same as embodiment 1, the difference is that step (5), step (5) is specifically: dry heat setting makes the fabric surface form a layer of high-temperature-resistant film and The anti-wrinkle finishing agent reacts with the fabric and the anti-yellowing finishing agent; the temperature is 140°C and the time is 20min.

[0046] Fabric anti-yellowing and anti-wrinkle performance test:

[0047] The fabric after finishing is soft to the touch. Before and after fabric finishing, before and after fabric finishing, use a computer color measuring and matching instrument to measure the apparent color depth at the maximum absorption wavelength before and after finishing at room temperature, and keep the test surface flat, and take the average of multiple measurements value, the color difference of the fabric can be obtained, and the color difference is 0.3; according to GB / T 3819-1997 "Textile Fabric Crease Recovery Test Recovery...

Embodiment 3

[0049] According to embodiment 1, step (1)-step (4) is the same as embodiment 1, the difference is that step (5), step (5) is specifically: dry heat setting makes the fabric surface form a layer of high-temperature-resistant film and The anti-wrinkle finishing agent reacts with the fabric and the anti-yellowing finishing agent; the temperature is 130°C and the time is 20min.

[0050] Fabric anti-yellowing and anti-wrinkle performance test:

[0051] Before and after fabric finishing, use a computer color measuring and matching instrument to measure the apparent color depth at the maximum absorption wavelength before and after finishing at room temperature, and keep the test surface flat, and take the average value of multiple measurements to obtain the color difference of the fabric. It is 0.3; according to GB / T 3819-1997 "Test Recovery Angle Method for Crease Recovery of Textile Fabrics", test the warp and weft recovery angles of samples, and the warp and weft recovery angles ...

Abstract

The invention relates to a preparation method of a regenerated cellulose fabric with anti-yellowing and anti-wrinkle functions. The method comprises the following steps: pretreating the regenerated cellulose fabric, and then preshrinking; and mixing the solution containing the anti-yellowing finishing agent with the solution containing the anti-wrinkle finishing agent to obtain a mixed finishing solution, soaking the pre-shrunk fabric in the mixed finishing solution for finishing, and then sequentially carrying out loose processing, dehydration, tentering and drying. According to the method, effective combination of the anti-yellowing finishing agent and the fabric can be achieved without adding an adhesive or a cross-linking agent into the finishing liquid, the whole finishing process does not involve absorption and release of formaldehyde, the cost is low, environmental protection is achieved, and the finished fabric has good anti-yellowing and anti-wrinkle performance.

Description

technical field [0001] The invention belongs to the technical field of textile finishing, in particular to a preparation method of regenerated cellulose fabric with anti-yellowing and anti-wrinkle functions. Background technique [0002] At the beginning of the 20th century, regenerated cellulose fiber has been industrialized, because it has properties similar to cotton, and its moisture regain meets the physiological needs of human skin. At the same time, it has good luster, handle, and drape. Dyeing and other advantages, widely used in medical and health, home textiles, clothing and other fields. With the development of the economy and market, the reduction of cultivated land and the depletion of fossil resources such as oil and natural gas, the production of synthetic fibers will be more and more restricted. As a green, environmentally friendly and renewable resource, cellulose has gained an unprecedented opportunity for development. Utilizing the characteristics of reg...
