Composite fabric is a new type of fabric made by bonding one or more layers of textile materials, non-woven materials and other functional materials. Material. Suitable for sofas, clothing and other textiles, it is one of the indispensable fabrics for people’s home life.
Composite fabric is a kind of fabric that uses microfiber in Specific textile processing and unique dyeing and finishing, then processed on “composite” equipment. The English name of composite fabric is: “Lamination Fabric” and “Soft Shell Fabric”. Because the composite fabric uses microfiber, the fabric has high cleaning ability, that is, decontamination ability.
Common compounds
Composite fabrics apply “new synthetic fiber” high technology and new materials, and have many excellent properties (compared with ordinary synthetic fibers), such as the fabric is fine, clean, delicate, elegant, and warm, and the fabric has a plump appearance, windproof, and breathable , has a certain waterproof function, and its main features are warmth retention and good breathability.
Another feature of this fabric is: wear resistance It has good properties. Microfiber fabrics feel soft, breathable and moisture-permeable, so they have obvious advantages in terms of touch and physiological comfort. Microfiber fabrics have poor wrinkle resistance (this is because the fibers are soft and have poor elastic recovery after wrinkles). (caused by); in order to overcome this shortcoming, a “composite” process was adopted, which greatly improved the shortcomings of poor wrinkle resistance of microfiber fabrics. Composite fabric is a popular outerwear fabric in Europe and America.
Classification of composite fabrics
1. Combination of woven fabrics and knitted fabrics
2. Knitted fabrics and knitted fabrics composite
3. Woven fabric and woven fabric composite
Sports and leisure clothing uses knitted fabric and composite knitted fabric, which has the effect of woven fabric and good elasticity, so in the eyes of consumers of this type of clothing , is still relatively popular and loved by the public.
Ordinary composite fabric
The fabric and lining are bonded with an adhesive to improve the texture of the fabric and are suitable for process simplification and large-scale production of clothing processing.
Functional composite fabric
The composite fabric has waterproof, moisture-permeable, radiation-resistant, and Special functions such as washing and anti-wear.
Process flow
Six internationally popular composite processes, namely hot sol powder dots Coating composite technology, hot sol slurry point composite process, hot sol dusting composite process, hot sol two-point composite process, polyurethane spray composite process, polyurethane roller coating composite process are newer fabrics that are favored by the market. A kind of fabric developed is, simply put, a fabric made of two fabrics combined together. 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. The door width of composite fabrics is limited to the size of the two fabrics before they are combined, which can generally reach 145CM.
Every batch of composite fabrics must be effectively processed For ground maintenance treatment, first laminate the reverse fabric (the film is a transparent material similar to nylon film), bond it with chemical materials, and then perform maintenance treatment.
The longer the maintenance treatment, the better the fastness of the fabric bonding and the degree of fusion of the adhesive. Generally, domestic adhesives need three days. Maintenance time, imported adhesives take five days or more.
The time required for the adhesive to fully integrate into the space between the fabric and the membrane will also affect the subsequent bonding effect with the front fabric.
Common composite gluing methods
The maintenance and treatment workshop is completely enclosed, and a certain temperature and humidity must be maintained indoors.It allows the adhesive to fuse naturally. If the temperature is increased in order to complete it quickly, although it can speed up the operation process of the finished product, it often happens that during the sewing process of the finished fabric, the yarn of the fabric is broken by the needle, and the feel also changes. If they are hard, there will be a rustling sound when they rub against each other, indicating that the adhesive has solidified on the fabric and made the yarn of the fabric hard. If you are making composite fabrics, you must pay attention to giving enough time to the composite manufacturers, and don’t lose the big for the small.
