Problems solved by technology

[0003] At present, most of the experimental work clothes on the market in my country do not have special water and oil repellency properties, and do not have good protective functions against acids, alkali solutions and organic experimental reagents. Most of the test work clothes with good protective properties have poor wearing comfort and poor air permeability. If worn for a long time, it will cause discomfort and stuffiness, and the test work clothes will be greatly reduced or even lose their original protective performance after repeated washing

Embodiment 1

[0031] The present invention is a kind of preparation method of breathable water-repellent and oil-repellent polyester-cotton fabric, the steps of this preparation method are:

[0032] The first step is to prepare raw materials: In order to achieve the water and oil repellency of the fabric, the raw materials are polyester high-shrinkage yarn and ultra-fine cotton fiber with a diameter of 5 μm.

[0033] The second step, raw material spinning: In order to make lotus leaf-like fabrics to achieve the water repellency of the fabrics, the contact angle of water on the surface of the fabrics is greater than 90°, and the surface roughness reaches the micron level or even nanometer level, and the crepe weave is used to weave The polyester high-shrinkage yarn and superfine cotton fiber are mixed and woven in a ratio of 7:3 to make a lotus-like fabric. The warp density of the lotus-like fabric is 260 threads / cm, and the weft density is 150 threads / cm. The buckling wave height of the fib...

Embodiment 2

[0040] On the basis of Example 1, in order to achieve a better production effect in the present invention, so that the fabric obtains better water and oil repellency and air permeability, a preferred embodiment is also: in the first step, the superfine cotton fiber The diameter is 15 μm; the warp density of the imitation lotus leaf fabric in the second step is 300 threads / cm, and the weft density is 200 threads / cm, and the buckling wave height of the fibers in the gained imitation lotus leaf fabric is 25 μm; in the fourth step, the hydrophilic resin The amount of PA-1 is 8% of the weight of the imitation lotus leaf fabric; in the fifth step, the concentration of the organic fluorine finishing agent FG-910 in the organic fluorine finishing solution is 20g / L, and the concentration of the softener Demeirou SG is 15g / L , the pH value of the organic fluorine finishing solution is 6; in the sixth step, the imitation lotus leaf fabric is put into the organic fluorine finishing solutio...

Embodiment 3

[0042] On the basis of Example 2, in order to achieve a better production effect in the present invention, so that the fabric obtains better water and oil repellency and air permeability, a preferred embodiment is also: in the first step, the superfine cotton fiber The diameter is 8 μm; the warp density of the imitation lotus leaf fabric in the second step is 275 threads / cm, and the weft density is 170 threads / cm, and the buckling wave height of the fibers in the gained imitation lotus leaf fabric is 15 μm; in the fourth step, the hydrophilic resin The amount of PA-1 is 6% of the weight of the imitation lotus leaf fabric; in the fifth step, the concentration of organic fluorine finishing agent FG-910 in the organic fluorine finishing solution is 14g / L, and the concentration of Demeirou SG softener is 11g / L , the pH value of the organic fluorine finishing solution is 5.5; in the sixth step, the imitation lotus leaf fabric is put into the organic fluorine finishing solution at a ...

Abstract

The invention discloses a preparation method of permeable water-and-oil repellent polyester cotton fabric. The method adopts crepe weave weaving manner to prepare superfine cotton fibers and terylene high shrinkage silk into lotus leaf imitated fabric; the surface roughness of the lotus leaf imitated fabric is of the micron scale, and the contact angle of water on the surface of the fabric is larger than 90 degrees; then, after a hydrophilic coating material is adopted for coating treatment of the lotus leaf imitated fabric, a water-and-oil repellent agent and a softening agent are adopted for arranging the lotus leaf imitated fabric; finally, the lotus leaf imitated fabric is subjected to saponification and drying process to become water-and-oil repellent polyester cotton fabric with favorable permeability. According to the method, crepe weaves are adopted for weaving the superfine fibers, so that the surface roughness of the fabric is of the micron scale and the fabric has better water repellency; moreover, the arrangement via the organic fluorine agent and the coating treatment via the resin are combined, so that the fabric has stronger water-and-oil repellency, washing fastness to a fluorine-containing agent, moisture absorption and permeability.

Description

technical field [0001] The invention relates to a preparation method of a garment fabric, in particular to a preparation method of an air-permeable water-repellent and oil-repellent polyester-cotton fabric. Background technique [0002] In recent years, with the gradual increase of the country's investment in education and scientific research projects, the number of students and researchers engaged in scientific research has increased significantly, and more and more people have paid attention to the safety of experiments and scientific research. As a safety protection The experimental overalls have not received enough attention for a long time. [0003] At present, most of the experimental work clothes on the market in my country do not have special water and oil repellency properties, and do not have good protective functions against acids, alkali solutions and organic experimental reagents. Most of the test work clothes with good protective properties have poor wearing co...
