【Laundry talk】Coated and composite fabrics, why do the glues not open and harden after being washed?
【Coated Fabric】
Coated fabric is a layer of polymer or other materials covered on fabric (or nonwoven fabric) to form a combination of fabric and polymer. Complex.
The coated fabric uses solvent or water to dissolve the required coating particles (including PU glue, A/C glue, PVC, PE glue) into a saliva-like shape, and then in a certain way (Rotary screen, scraper or roller) is evenly applied on the fabric (including cotton, polyester, nylon and other base materials), and then fixed by the temperature in the oven to form a uniform layer of covering glue on the surface of the fabric.
Precautions for washing and ironing this type of fabric:
Coated fabrics are not suitable for dry cleaning because It may cause the paint slurry to dissolve or degreasing and hardening. The best washing method is to wash it by hand! It is forbidden to iron directly from the front to avoid the problem of coating melting and adhesion!
【Composite Fabrics】
Composite fabrics can be understood as two (or more) fabrics with different compositions, different organizations or different dyeing and finishing processes that are organized through a special bonding process. Together with new fabrics.
Composite fabrics apply the high technology and new materials of “new synthetic fibers” and have many excellent properties (compared with ordinary synthetic fibers), such as the fabrics are fine, clean, delicate, elegant and warm, and the fabrics are It has a plump appearance, is windproof, breathable, and has a certain waterproof function.
Its main features are warmth and good breathability.
Another feature of this fabric is: good wear resistance, microfiber fabric feels soft, breathable, and moisture permeable, so it has obvious advantages in terms of touch and physiological comfort. Microfiber fabric The wrinkle resistance of microfiber fabrics is poor (this is due to the soft fiber and 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 fabric is a popular outerwear fabric in Europe and America.
Notes on washing and stain removal:
High-strength and long-lasting composite fabrics are prohibited Dry cleaning over time may cause the composite fabric to open and bubble. Because tetrachlorethylene dissolves the adhesive layer during the dry cleaning process, it causes glue bubbling problems. It is forbidden to use oil-based stain removers when removing stains, or scraping with a local scraper, which are the root causes of glue bubbling!
Pa hot melt adhesive film: The application range of pa hot melt adhesive film is slightly wider than that of other hot melt adhesive films. The same is true for fabric composites, such as shoe materials. For lamination, bag interior fabric lamination and home textile fabric lamination, the hot melt adhesive film used is mainly made of PA. Its characteristics are: good resistance to dry cleaning and water washing. The functional PA film also has excellent flame retardancy and resistance to boiling water.
Pes hot melt adhesive film: The washing resistance of pes hot melt adhesive film is better than that of pa hot melt adhesive film. In terms of fabric compounding, it is mainly used in flocking transfer printing, textile lamination and embroidery. Composite bonding of badges, etc.
Tpu hot melt adhesive film: Tpu hot melt adhesive film also has relatively good washing resistance, but is not resistant to dry cleaning. It has good tensile properties and high elasticity, and is more suitable for the composite use of sports fabrics.
Eva hot melt adhesive film: Eva hot melt adhesive film has a lower melting point and is as washable as tpu hot melt adhesive film, but not dry cleaning resistant. It can be applied to non-woven fabrics, wall coverings and other materials. Composite bonding.
The lamination of fabrics can basically be selected around the above four hot melt adhesive films. In the past, some customers were more concerned about whether the size specifications could meet their needs. In fact, the size can be adjusted according to needs, and the focus should be shifted to the selection.
