Composite fabrics can be used to make clothes, sofas, bedding, etc., and are increasingly used in our lives.
Composite Fabric Lamination Fabric, Soft Shell Fabric
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. Suitable for sofas, clothing and other textiles.
Composite fabrics apply the high technology and new materials of “new synthetic fibers” and have many excellent properties (compared with ordinary synthetic fibers). For example, the fabrics are fine, clean, delicate, elegant, and warm, and the fabrics have a full and plump appearance. It is windproof, breathable, and has a certain waterproof function. Its main features are warmth retention and good breathability.
Classification of composite fabrics
Composite fabrics are further divided into ordinary composite fabrics (made by bonding fabrics and linings with adhesives to improve the texture of the fabric and are suitable for clothing processing Process simplification and large-scale production) and functional composite fabrics (composited fabrics have special functions such as waterproof, moisture-permeable, radiation resistance, washing resistance, and wear resistance).
Two-layer composite fabric and three-layer composite fabric❂ Two-layer composite fabric
The second-layer composite fabric is made of outer fabric and TPU, PTFE film, and the outer fabric is made of polyester, nylon or nylon-polyester Blended fabric, soft to the touch, wear-resistant, tear-proof, good color, excellent waterproof, breathable, windproof, long durability. The surface of the fabric is treated with Teflon water-repellent treatment.

When using two-layer composite fabrics to make garments, a lining must be hung, or a fleece thermal layer can be used as a jacket.
Technical properties of the two-layer composite fabric:
Water pressure resistance>10000mm
Moisture permeability>5000g/m2.24h
Wind resistance>100%
Scope of application: Skiing , cycling, backpacking, hiking, golf, casual wear, etc.
❂ Three-layer composite fabric
Three-layer composite fabric is made of outer fabric, e-PTFE film, and inner warp-knitted mesh. There is no need to hang the lining when making the garment. The outer fabric is made of polyester, nylon or nylon-poly blended fabric, which has a light and thin feel, is tear-resistant, wear-resistant, has good color, has excellent waterproof and windproof effects, better breathability and long durability. The surface of the fabric is treated with Teflon water-repellent treatment.
Schematic diagram of three-layer fabric
Three-layer composite fabric is made by laminating 100% pure polyester thickened high-strength non-woven fabric and polytetrafluoroethylene (PTFE) microporous film using special technology and equipment. It has many functions such as virus blocking, antibacterial, antistatic, anti-blood penetration, waterproof, moisture permeable, windproof, and warmth retention properties, and is comfortable and lightweight to wear. The anti-microparticle transmission rate is over 90%, making it impossible for viruses and bacteria to pass through.
Technical performance of three-layer composite fabric:
Water pressure resistance>10000mm
Moisture permeability>6000g/m2.24h
Wind resistance>100%
Scope of application: Skiing , cycling, backpacking, mountain climbing, etc.
Composite Technology
There are 6 internationally popular composite processes, namely hot sol powder point coating composite process, hot sol slurry point composite process, hot sol dusting composite process, hot sol double point composite process, Polyurethane spraying composite process, polyurethane roller coating composite process. 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. If it is a composite of knitted fabrics, the width of the knitted fabric will be wider than that of cotton woven fabric.
The composition equation of composite fabrics: The finished products purchased from the two fabrics ① Composite film factory ② Intermediate maintenance and processing factory ③ Post-finishing factory ④ Each batch of fabrics that have been composited 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 degree of fusion of the adhesive. Be better. Generally, domestic adhesives require three days of maintenance, and imported adhesives require five days or more. The time required for the adhesive to fully integrate into the fabric and membrane will also affect the subsequent and front-facing processes. The effect of fabric bonding.
The maintenance and processing workshop is completely closed. A certain temperature and humidity must be maintained indoors to allow 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 will often Defects will occur. For example, during the sewing process of the finished fabric, the yarn of the fabric is broken by the needle, and the feel becomes hard. There will be a rustling sound when rubbing against each other, indicating that the adhesive solidifies on the fabric and changes the yarn of the fabric. Gotta get hard.
After the maintenance-treated reverse side is completed, the front fabric is laminated and the same maintenance treatment is required. It is worth noting that when the front side is laminated, the front and back fabrics should be aligned with the silk strands to avoid serious weft skew. , straight wire twisting and other phenomena.
It needs to be emphasized that the composite fabric cannot be recombined. Even if the material is used for stripping, the yarn of the fabric will be greatly affected, and it will become harder and harder, and when sewing into garments , the fabric is very easy to be punctured by needles. Since the film adhesive uses chemical materials, it will have a certain physical reaction to nylon fabrics. Therefore, it is recommended that customers use polyester fabrics.Effectively controlling the color of the fabric before lamination and the color after lamination, as well as water pressure resistance and breathability index all have a certain impact.
