1. Overview of flame-retardant fabrics Market research shows that flame-retardant fabrics for clothing are a new type of material made by bonding one or more layers of textile materials, non-woven materials and other functional materials. Flame-retardant fabrics are further divided into ordinary flame-retardant fabrics (made by bonding fabrics and linings with adhesives to improve the texture of the fabric and suitable for simplification of clothing processing techniques and large-scale production) and functional flame-retardant fabrics (compounded The fabric has special functions such as waterproof, moisture permeability, radiation resistance, washing resistance, and wear resistance). There are six internationally popular composite processes, namely hot sol powder dot coating composite process, hot sol slurry dot composite process, hot sol dusting composite process, hot sol double point composite process, polyurethane spray composite process, The fabric compounded by the polyurethane roller coating technology is a new type of fabric developed by the market. In short, it is a fabric composed of two fabrics. In the past, the most common composite was the composite of suede fabric and wool. Nowadays, any fabric can be used to composite it together. 2. Varieties of flame-retardant fabrics: The width of flame-retardant fabrics is limited to the size before the two fabrics are combined, which can generally reach 145CM. If it is a composite of knitted fabrics, the width of the knitted fabric as mentioned earlier is wider than that of cotton woven fabric. There are several types of composites: woven fabrics and knitted fabrics; knitted fabrics and knitted fabrics; woven fabrics and woven fabrics. Sports and leisure clothing uses knitted fabric and composite knitted fabric, which has the effect of woven fabric and good elasticity. Therefore, in the eyes of consumers of this type of clothing, it is still relatively popular and loved by the public. 3. The composition equation of flame-retardant fabrics. The finished products purchased from the two fabrics are ① the composite film factory ② the mid-term maintenance treatment factory ③ the post-finishing factory ④ the fabric is completed. Each batch of composite fabrics must be effectively maintained, and the reverse side of the fabric must be processed first. The lamination (the film is a transparent material similar to nylon film) is bonded with chemical materials and then maintained. The longer the maintenance treatment, the faster the bonding fastness to the fabric and the adhesive. The degree of integration is better. Generally, domestic adhesives require three days of maintenance, and imported adhesives require five days or more. To allow the adhesive to fully integrate into the space between the fabric and the film, time is required. The length will also affect the subsequent bonding with the front fabric. Finally, it needs to be emphasized that the composite fabric cannot be recombined. Even if materials are used for stripping, the fabric yarn will be greatly affected and will become harder and harder, and when sewing garments, The fabric is very easy to be punctured by needles. Therefore, it is recommended that customers use polyester fabrics, which can effectively control the color of the fabric before lamination and the color after lamination, as well as the water pressure resistance and breathability index, which have a certain impact.
