Composite fabric testing, have you known these
Composite fabric is a new type of material, which is made of one or more layers of textile materials, non-woven materials and other functional materials. It is suitable for textiles such as sofas and clothing, and is one of the indispensable fabrics in people's family life.

Composite fabric is a kind of superfine fiber, which is used for specific textile processing and unique dyeing classification, and then processed with composite equipment. The English of the composite fabric is: Raminata Foundation and Softshel Foundation. Because the composite fabric adopts superfine fibers, the fabric has high cleaning ability, that is, strong decontamination ability.

common compound

The composite fabric adopts new synthetic fiber high-tech new material, which has excellent performance (compared with ordinary synthetic fiber), such as the fabric is clean, delicate, elegant, warm, the fabric looks plump, windproof, breathable, and has a certain waterproof function. Its main features are Warm and breathable.

Another feature of the fabric is: good abrasion resistance, microfiber fabric feels soft, breathable, and wet, and has obvious advantages in touch and physiological comfort, and microfiber fabric has poor wrinkle resistance (this is due to the softness of the fiber and the elastic recovery after wrinkling) Poor); In order to overcome this shortcoming, a composite process is adopted, which greatly improves the shortcoming of poor wrinkle resistance of microfiber fabrics. Composite fabric is a popular outerwear fabric in Europe and the United States.

Classification of composite fabrics.

1. Combination of woven and knitted fabrics.

2. Combination of knitted fabric and knitted fabric.

3. Combination of woven fabric and woven fabric.

Sports and leisure clothing adopts knitted fabric and composite knitted fabric, which has the advantages of good weaving and good elasticity. Therefore, in the eyes of consumers of such clothing, they are still very popular with the public.

Ordinary composite fabric.

The fabric and the inner material are bonded together by an adhesive to improve the texture of the fabric, which is suitable for simplifying the garment processing process and mass production.

Functional composite fabric.

The composite fabric has special functions such as waterproof and moisture permeability, radiation resistance, washing resistance and wear resistance.

process flow

Six popular composite processes in the world, namely thermal sol powder dot coating composite process, thermal sol paste dot composite process, thermal sol powder dot composite process, thermal sol double point composite process, polyurethane spray composite process, polyurethane roll coating composite process Composite fabric is a new type of fabric developed by the market, in short, it is a composite fabric of two fabrics. In the past, the more common compound was a combination of suede and wool, but now they can be compounded with any fabric. The door range of the composite fabric is limited to the size of the two fabrics before the composite, generally up to 145cm.

Each batch of composite fabric should be effectively maintained and handled. First, the composite film of the reverse fabric (the film is a transparent material like nylon film) should be bonded with chemical materials, and then maintained and processed.

The longer the maintenance treatment, the better the fastness of the fabric adhesive and the fusion of the adhesive. Generally speaking, domestic adhesives need three days of maintenance, and imported adhesives need five days or more.

Fully integrate the adhesive between the fabric and the film, and the length of time will also affect the bonding effect with the front fabric in the next step.

Commonly used composite gluing methods:

The maintenance and processing workshop is completely closed, and a certain temperature and humidity are maintained indoors to allow the adhesive to fuse naturally. Although it can speed up the operation process of the finished product in order to quickly complete and increase the temperature, it often happens that the finished fabric is in the process of sewing. The thread is needled, it feels hard, and there is a rustling sound when rubbed, the adhesive is cured on the fabric, and the fabric yarn becomes stiff. When making composite fabrics, you must pay attention to giving the composite manufacturer enough time, and don't lose a lot because of a small one.
