Coated fabric refers to a layer of polymer coating on the surface of the fabric, which is used to increase the functionality and beauty of the fabric. Coated fabrics are widely used in clothing, footwear, leather products, home accessories and other fields. This paper will briefly introduce the production process and processing technology of coated fabric.
First, the production process of coated fabric
(1) Fabric selection
The production of coated fabrics must first choose the appropriate fabric, the general selection of fabric types are textile fabrics, synthetic fiber fabrics, nonwovens and yarns. When selecting materials, it is necessary to consider the quality, strength, air permeability and water absorption of the fabric to ensure the stability and good quality of the coating effect.
(2) Coating treatment
Coating treatment is a key link in the production of coated fabrics, mainly including the bottom coating, top coating and drying processes, in addition to the need to add additives, fillers, stabilizers and other materials to enhance the coating effect.
1. Bottom coating: Bottom coating is the first step of coating treatment, the main role is to enhance the wear resistance and fastness of the fabric. Generally, PU base coating, PVC base coating or acrylic base coating is used instead of adhesive.
2. Surface coating: Surface coating is the core of coating treatment, and its main function is to enhance the waterproof, oil-proof, dustproof and thermal insulation functions of the fabric. Generally, materials such as PU coating, PVC coating or acrylic coating are used for coating treatment.
3. Drying: drying is the last link of coating treatment, the main role is to dry the coating fixed on the surface of the fabric, so that it can achieve the required tear resistance and wear resistance.
(3) printing treatment
Printing treatment is an important processing link of coated fabrics, and more decorative effects can be added to coated fabrics through printing technology. Printing coatings generally include ordinary printing, offset printing, transparent printing and immersion printing and other technologies.
(4) After finishing
Finishing is the final step in the production of coated fabrics, the main purpose is to make the fabric more comfortable and improve its feel and appearance. Finishing generally includes washing, softening or rolling.
Second, coating fabric processing technology
The processing technology of coated fabric mainly involves cutting, sewing and hot sticking of fabric.
(1) Fabric cutting
Fabric cutting is the cutting of fabric according to the design pattern and size in order to facilitate sewing and processing into the finished product. When cutting fabric, it is necessary to pay attention to the size and specifications of the selected tools, tools and materials.
(2) Sewing
Sewing is the process of stitching the cut fabric to complete the finished product. When stitching, it is necessary to pay attention to the stability of the thread and the line to ensure the quality and fastness of the finished product.
(3) Hot paste
Hot paste refers to the material to be pasted on the fabric by heating, increasing the waterproof, oil proof, dust proof and heat preservation effect of the fabric. Hot stickers are commonly used to make bags, shoes and hats. It is necessary to pay attention to the control of temperature and time when hot pasting to ensure the effect and fastness of bonding.
To sum up, the production process and processing technology of coated fabrics are very complex, requiring careful operation and processing by manufacturers to ensure the quality and fastness of coating effects and finished products.
