As the name implies, it is a method in which two or more layers of the same or different materials lamination fabric are combined into a whole by heating and pressing with or without adhesives. Also known as the lamination method. It refers to a forming method that combines multiple layers of the same or different materials into a whole under heating and pressure. Through the sizing method such as barrel coating or spraying, one or more layers of bonding and pressing are carried out and then passed through a rotating drum. The base material can be preheated with an open flame or a belt heater, but it is best to use a metal heating drum to preheat. The inside of the drum is heated by electricity or steam, and the temperature reaches 177°C.
Six kinds of composite fabric processes that are popular in the world, namely, hot sol powder dot coating composite fabric technology, hot sol paste dot composite fabric technology, hot sol dusting composite fabric technology, hot sol two-point composite fabric technology, polyurethane spraying composite Fabric technology, polyurethane roll-coated composite fabric technology composite fabric is a relatively new type of TPU composite fabric and PTFE composite fabric developed by the market, in short, it is a composite fabric of two kinds of fabrics. In the past, our most common compound was the compound of suede fabric and wool, but now it can be compounded with any fabric. Kunshan Yingjie Textile Import and Export Co., Ltd. believes that composite fabrics will shine in the future fabric market and clothing market.Composite fabric is also called waterproof and breathable fabric.
It is a new type of textile fabric. Its composition is made of polymer waterproof and breathable material (PTFE membrane or tpu membrane) and fabric composite fabric. The main functions of waterproof and breathable fabrics are: waterproof, breathable, breathable, insulating, windproof, and warm. In terms of production technology, the technical requirements for waterproof and breathable fabrics are much higher than those of general waterproof fabrics; at the same time, from the perspective of quality, waterproof and breathable fabrics also have functional characteristics that other waterproof fabrics do not have. The waterproof and breathable fabric strengthens the air-tightness and water-tightness of the fabric. At the same time, its unique vapor permeability can quickly discharge water vapor inside the structure, avoid mold breeding in the structure, and keep the human body always dry, which perfectly solves the problem of ventilation, windproof, and waterproof.
Heat preservation and other issues are a new type of healthy and environmentally friendly fabric. The preheating of the substrate can improve the bonding effect of the laminated fabric. The preheated base material is drawn onto the pressure roller to meet the molten material flowing down from the die, so that the base material and the molten material are bonded in the nip, and the bonding state and appearance are controlled by the hardness of the rubber pressure roller. Laminated fabrics are widely used in our lives. For example, knitted laminated polar fleece fabrics on thermal clothing, laminated lamb fleece, outdoor sportswear, TPU laminated nylon, PU laminated fabric, base, such as mesh cloth layer Laminated non-woven fabrics, lace laminated fabrics, laminated fabrics are also useful in the sponge laminated fabrics of sofas, cushions, ceilings, and medical applications.
