Composite fabric knowledge and composite fabric principle
6 kinds of composite processes popular in the world, namely hot melt powder point coating composite process, hot melt slurry point compounding process, hot melt dusting compounding process, process, hot melt double point compounding process, polyurethane spraying composite process, polyamine Grease roll coating composite process
The garment composite fabric is a new type of material obtained by bonding one or more layers of textile materials, non-woven materials and other functional materials. The composite fabric is divided into ordinary composite fabrics (bonding fabrics and linings through adhesives to improve fabric texture, suitable for process simplification and scale production of garment processing) and functional composite fabrics (the composite fabric is waterproof and moisture permeable) , special functions such as radiation resistance, washing resistance and abrasion resistance).
The width of the composite fabric is limited to the size of the two fabrics before compounding, which can generally reach 145CM. In the case of a composite of knitted fabrics, the width of the knitted fabric mentioned in the front is also wider than that of the cotton woven fabric.
Composite fabrics are a new type of fabric developed by the market. In short, it is a fabric that combines two fabrics. In the past, our more common compound was the combination of suede fabric and wool, which can now be compounded with any fabric. Personally think that composite fabrics will shine in the future market…
The varieties have the following composite methods: woven fabrics and knitted fabrics composite; knitted fabrics and knitted fabrics composite; woven fabrics and woven fabrics composite. Sports and leisure clothing uses knitted fabrics and knitted fabrics, and has the effect of woven fabrics. The elasticity is also good, so in the eyes of consumers of such clothing, it is still popular among the public…
Each batch of composite fabrics must be effectively treated. First, the reverse fabric is laminated (the membrane is a transparent material similar to nylon film), bonded with chemical materials, and then processed for maintenance and maintenance. The longer the bonding strength of the fabric and the bonding degree of the adhesive are better, generally the domestic adhesive requires three days of maintenance time, the imported adhesive takes five days or longer, and the adhesive is required. Fully blended between the fabric and the film, the length of time will also affect the next bond with the front fabric.
The composition of the composite fabric:
Finished products purchased from two fabrics (see the weaving or knitting process)–> Composite Film Factory –> Medium Maintenance Plant –> Finishing Plant –> Fabric Finishing
The maintenance workshop is completely closed. It is necessary to maintain a certain temperature and humidity in the room to allow the adhesive to naturally fuse. If the temperature is increased for quick completion, although the operation of the finished product can be accelerated, it often happens. During the sewing process, the fabric yarn is pierced by the needle and the hand feels hard. The mutual friction will have a rustling sound, indicating that the adhesive is solidified on the fabric and the fabric yarn is hardened. If you are doing composite fabrics, you must pay attention to the time to give the compound manufacturers, don’t lose because of small…
After the reverse side of the maintenance process is completed, the composite of the front fabric is also carried out, and the maintenance process is also carried out. It is worth noting that when the front side is compounded, the front and back fabrics should be aligned with the silk thread to avoid serious latitude, straight wire Twisting and other phenomena… It should be emphasized that the composite fabric cannot be recombined. Even if the material is peeled off, the yarn of the fabric will be greatly affected, and it will become harder and harder. When the fabric is very easy to be pierced by the needle.
Since the film adhesive uses chemical materials, there will be some physical reaction to nylon fabrics. Therefore, it is recommended that customers recommend polyester fabrics to effectively control the color of the composite front and the composite color. There is also a certain influence on water pressure resistance and air permeability index. The knowledge of this fabric needs to be followed up.
Composite fabrics often have irregular sideways, so the compound factory must be trimmed, which is beneficial to the cutting of the garment factory.
