Description
Technical Field
The invention relates to the technical field of fabric production, in particular to a preparation method of a waterproof and oilproof fabric.
Background
The fabric is a basic material for making clothes, and clothes with different functions, such as waterproof clothes, warm clothes and quick-drying clothes, can be made by using different fabrics. The common clothing fabrics are divided into two large series; woven fabric, which is mainly used for outer coats and shirts of clothing. Knitted fabric: underwear and sports series clothing of clothing, but because of the development of science and technology, knitted fabrics are also developed to be thick and stiff and smooth, and knitted underwear is gradually externalized, and knitted fabrics are woven, so that the knitted underwear becomes a supplement to outer garments. Along with the improvement of the life quality of modern people, the wearing requirements of the modern people are also higher and higher, the modern people are not limited to the shape and style of the clothing, and the modern people pay more attention to whether the fabric of the clothing is comfortable or not and whether the environment is protected or not.
Garment materials are commonly used.
One) cotton type fabric is a fabric woven by cotton yarn or cotton and cotton type chemical fiber blended yarn. The fabric has good air permeability, good hygroscopicity, comfortable wearing and strong practicability. Can be divided into two main types of pure cotton products and cotton blending.
Two) the fibrilia type fabrics are pure fibrilia fabrics woven by fibrilia and fabrics obtained by blending or interweaving fibrilia with other fibers, and are collectively called fibrilia type fabrics. The hemp fabric has the common characteristics of hard and tough texture, rough and stiff texture, coolness and comfort, good hygroscopicity, and is an ideal summer clothing fabric, and the hemp fabric can be divided into two types of pure spinning and blending.
Thirdly), silk type fabrics are high-grade varieties in textiles. Mainly refers to a fabric which takes mulberry silk, tussah silk, rayon and synthetic fiber filaments as main raw materials. It has the advantages of thinness, lightness, softness, smoothness, elegance and comfort.
Fourth), wool type fabrics are fabrics made of wool, rabbit hair, camel hair and wool type chemical fibers as main raw materials, generally wool is used as a main material, and the fabrics are high-grade clothing fabrics all the year round, and have the advantages of good elasticity, crease resistance, stiffness, wear resistance, strong heat retention, comfort, attractive appearance, pure color and the like, and are welcomed by consumers.
Fifth), the purified fiber fabric is popular with people because of its high fastness, good elasticity, stiffness, wear resistance, washing resistance, and easy storage and collection. The purified fiber fabric is a fabric woven from purified fibers. Its characteristics are determined by the characteristics of the chemical fibers themselves. The chemical fiber can be processed into a certain length according to different requirements, and woven into fabrics such as silk-like, cotton-like, hemp-like, elastic wool-like, medium-length wool-like and the like according to different processes.
The functionalization of the fabric is the basis for realizing the functionalization of the garment, and the functionalization of the garment can be realized by improving the surface property of the fabric.

(2) Preparing a second solution: uniformly mixing butyl methacrylate, butyl acrylate, methyl methacrylate, styrene and hydroxypropyl acrylate, adding an initiator ammonium persulfate aqueous solution, heating to 81-83 ℃ for polymerization reaction to obtain a hydroxyl-containing acrylic resin solution;
(3) Emulsifying the solution: mixing fluorine-containing carboxyl silicone oil and hydroxyl-containing acrylic resin solution according to the mass ratio of 1:1, and adding an emulsifying agent to emulsify to obtain a first finishing liquid, wherein the emulsifying agent can be AEO3 or AEO9 emulsifying agent;
the first finishing liquid contains rich Si-O bonds and C-F bonds, and a large number of polymers of C-F chain links are arranged on the outermost layer of the film in the form of C-F on the surface of the functional coating film, so that the interface energy of the fluorine-containing polymer in the dyeing and finishing process is greatly reduced, and the textile has good waterproof and oil-proof functions.
Because the Si-O bond has high bond energy, large flexibility of a molecular chain, high temperature resistance, low surface energy and the surface of the cloth is coated with a layer of polymer containing the high Si-O bond, the fabric has good waterproof property, high temperature resistance, stain resistance and the like. The first finishing liquid is coated on the surface of the fabric, so that the compactness of the fabric can be improved, the water absorption rate is obviously reduced, and the penetration of the liquid containing lipophilic groups is prevented. When the polymer forms a film on the fiber surface of the fabric, functional groups contained in molecular side chains of the polymer are arranged towards the air direction, active groups are easy to react and crosslink and bond with the fiber, and finally a layer of smooth film covers the fiber surface to play a role in blocking water and oil drops.
(4) Preparing a second finishing liquid: mixing waterborne polyurethane, titanium dioxide, tin antimony oxide and a thickener to prepare a second finishing liquid, wherein the mass ratio of the waterborne polyurethane to the titanium dioxide to the tin antimony oxide is 90:5-6:7-9;

baking refers to a dyeing and finishing process that promotes the fixation of pigments applied to a fabric or causes a finishing agent on the fabric to react chemically by a dry heat treatment. In the pigment dyeing and pigment printing processes, baking is a process of promoting the crosslinking reaction of the adhesive and bonding, crosslinking and fixing pigment particles and fibers; in the crease-resistant finishing process of the fabric, baking is a process of promoting the resin primary shrinkage body of the finishing agent to generate crosslinking reaction with the fiber or the primary shrinkage body to generate high polymer by self polymerization in the presence of a catalyst. The method comprises the steps of firstly, performing a low-temperature pre-baking process to prevent resin or paint from rapidly migrating to the surface of the fabric to cause negative and positive surfaces and surface resin, and then performing a high-temperature baking process to achieve the aim of promoting crosslinking chemical reaction.
(6) Soaking the fabric with the heat insulation layer in a first finishing liquid for 30-45s, taking out, wherein the concentration of the first finishing liquid is 2.3-2.6%, extruding and pressurizing on a small roller press to remove redundant liquid, and then performing secondary pre-baking and secondary baking, wherein the temperature of the secondary pre-baking is 110-130 ℃ for 4min, the temperature of the secondary baking is 120-140 ℃ for 3min, and cooling to obtain the waterproof and oilproof fabric with the heat insulation layer.
