Composite fabric is a new type of material made by bonding one or more layers of textile materials, non-woven materials and other functional materials. Composite fabrics are divided into ordinary composite fabrics (fabrics and linings are bonded through a binder to improve the texture of the fabric, suitable for process simplification and mass production of clothing processing) and functional composite fabrics (composite fabrics are waterproof and breathable) , Radiation resistance, washing resistance, anti-wear and other special functions). Six kinds of composite processes that are popular in the world, namely hot sol powder dot coating composite process, hot sol paste dot composite process, hot sol powder composite: process, hot sol two-point composite process, polyurethane spray composite process, polyamine The fabric compounded by the grease roller coating compound process is a newer fabric developed by the market. In short, it is a fabric compounded by two fabrics. In the past, the most common compound was the compound of suede fabric and wool, but now it can be compounded with any fabric.

The width of the composite fabric is limited to the size of the two fabrics before the composite, which can generally reach 145CM. If it is a combination of knitted fabrics, Gament also mentioned that the width of knitted fabrics is wider than that of cotton woven fabrics. Varieties have the following composite methods: woven fabric and knitted fabric composite; knitted fabric and knitted fabric composite; woven fabric and woven fabric composite. Sports and leisure clothing uses knitted fabric composite knitted fabric, which has the effect of woven fabric and has good elasticity. Therefore, in the eyes of consumers of this type of clothing, it is still popular and popular among the public.

The composition equation of composite fabrics: the finished products purchased from two kinds of fabrics (see the process of woven fabric or knitted fabric) ①composite membrane factory ②mid-term maintenance treatment factory ③post-finishing factory ④fabrics must be effectively combined For maintenance treatment, first carry out the laminating of the reverse fabric (the membrane is a transparent material similar to nylon film), bonding with chemical materials, and then the maintenance treatment. The longer the maintenance treatment, the fastness to the fabric. The degree of fusion with the adhesive is better. Generally, domestic adhesives require three days of maintenance time, and imported adhesives require five days or longer. The adhesive must be fully integrated into the fabric and film. The length of time will also affect the subsequent bonding effect with the front fabric. The maintenance and treatment workshop is completely enclosed. It is necessary to maintain a certain temperature and humidity indoors to allow the adhesive to blend naturally. If the temperature is increased for quick completion, although it can speed up the operation of the finished product, it often happens. During the sewing process of the fabric, the fabric yarn is broken by needles, and the hand feel becomes hard. There will be a rustling sound when rubbing against each other, indicating that the adhesive is solidified on the fabric and the fabric yarn becomes hard. If you are making composite fabrics, you must pay enough time to the composite manufacturer, and don't lose too much.

After the maintenance treatment of the negative side is completed, the front fabric is compounded, and the same maintenance treatment is required. It is worth noting that when the front is compounded, the front and back fabrics should be aligned with the silk strands to avoid serious weft skews and straight threads. Phenomena such as twisting.

It should be emphasized that the composite fabric cannot be recombined. Even if the material is used for stripping, it will greatly affect the yarn of the fabric and become harder and harder. Moreover, the fabric is very easy to sew into a garment. Pierced by a needle. Since the lamination adhesive uses chemical materials, it will have a certain physical reaction to nylon fabrics. Therefore, it is recommended that customers use polyester fabrics, which can effectively control the color of the fabric before and after the compound. , And the water pressure resistance and air permeability index have certain influence.
