Composite fabric
Composite fabric
Composite fabric is a new type of material formed by bonding one or more layers of textile materials, non-woven materials and other functional materials. Suitable for sofas, clothing and other textiles, it is one of the indispensable fabrics for people’s home life.
Introduction to composite fabrics
Composite fabric is made of microfiber through specific textile processing and unique dyeing and finishing, and then processed by “composite” equipment. 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 plump appearance, are windproof, and are breathable. It has a certain waterproof function, and its main features are warmth retention and good breathability. Because the composite fabric uses microfibers, the fabric has a high cleaning ability, that is, stain removal ability. Another feature of this fabric is that it has good wear resistance. 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 This is because the fibers are soft and have poor elastic recovery after wrinkles); in order to overcome this shortcoming, a “composite” process is adopted, which greatly improves the shortcomings of poor wrinkle resistance of microfiber fabrics. Composite fabrics are currently popular outerwear fabrics in Europe and the United States.
Composite fabric method
Woven fabrics are compounded with knitted fabrics; knitted fabrics are compounded with knitted fabrics; woven fabrics are compounded with 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.
Composite fabric composition equation
The finished products purchased from the two fabrics (please refer to the woven fabric or knitted fabric process) ① Composite film factory ② Interim maintenance treatment factory ③ Post-finishing factory ④ Each batch of fabrics that have been composited must be effectively maintained, and the reverse side must be carried out first The lamination of the fabric (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 of the fabric and the fusion of the adhesive will be. The degree is better. Generally, domestic adhesives require three days of maintenance, and imported adhesives require five days or more. The length of time will also affect the time required for the adhesive to fully integrate into the space between the fabric and the film. Next is the effect of gluing with the front fabric. The maintenance and treatment 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 for quick completion, although it can speed up the operation process of the finished product, it often happens that the finished product During the sewing process of the 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 has solidified on the fabric and hardened the yarn of the fabric. 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.
How to identify composite fabrics
1. Feel:
That is, if you touch the leather surface with your hands, if it feels smooth, soft, plump, and elastic, it is genuine leather; while the general artificial synthetic leather surface is astringent, rigid, and has poor softness.
2. Seeing:
Observe that the real leather surface has clearer pores and patterns. Yellow cowhide has more symmetrical fine pores, yak leather has thicker and sparse pores, goatskin has fish-scale pores, pigskin has triangular coarse pores, and artificial leather, although The pores are also simulated, but not clear. The following will introduce to you the characteristics and identification methods of pig leather, horse leather, cow leather, and sheep leather: cow leather is thin and high in strength, suitable for making leather shoes; sheep leather is light, thin and soft, and is an ideal fabric for leather clothing; pig leather It has good breathability and water vapor permeability, so it is more suitable for making underwear and children’s products; horse leather has a tight fiber structure and high strength, so it is better used for making leather pants and boots. Generally speaking, the thickness, density and distribution of pores on the leather surface are the main basis for distinguishing cow leather, pig leather, horse leather and sheep leather. Pig leather: The pores on the leather surface are round and large, extending into the leather at an angle. The pores are arranged in groups of three, and the leather surface shows many small triangular patterns. Cow leather: Both cattle leather and buffalo leather are called cow leather, but there are certain differences between the two. The pores on the surface of yellow cow leather are round and extend straight into the leather. The pores are dense and even, arranged irregularly, like a sky filled with stars. The pores on the surface of buffalo leather are larger than that of cattle leather, and the number of pores is less than that of cattle leather. The leather quality is looser and not as delicate and plump as cattle leather. Horse leather: The pores on the leather surface are oval, slightly larger than the pores of ox leather, and arranged more regularly. Sheep leather: The pores on the leather grain are oblate and clear. Several pores form a group and are arranged like fish scales.
3. Smell:
All real leather has a leather smell; artificial leather has a pungent plastic smell.
4. Ignite:
Tear off a little fiber from the back of real leather and artificial leather, and after burning it, if it emits a pungent smell and forms knots, it is artificial leather; if it emits a hairy smell and does not form hard knots.��It’s genuine leather.
Classification of composite fabrics
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 special functions such as waterproof, moisture permeable, radiation resistance, washing resistance, and wear resistance.
Technological Classification of Composite Fabrics
There are 6 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, polyamine spray composite process Fabrics compounded by grease roller coating technology are a new type of fabric developed by the market. In short, they are two fabrics compounded 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. If it is a composite of knitted fabrics, Garment also mentioned knitting before
Maintenance of composite fabrics
After the maintenance treatment is completed on the reverse side, 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 and straight yarn. Twisting and other phenomena. It needs to be emphasized that the composite fabric cannot be re-composited. Even if the material is used for stripping, the yarn of the fabric will be greatly affected and will become harder and harder. Moreover, the fabric will be very easy to sew when sewing garments. Pricked by a needle. 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, which can effectively control the color of the fabric before lamination and the color after lamination. , as well as water pressure resistance and breathability index have a certain impact. Composite fabrics often have uneven edges, so the composite factory must be required to perform edge trimming, which is beneficial to garment factory cutting. The width of the fabric is wider than that of cotton woven fabrics.
