[Laundry talk] Coated and composite fabrics, how come the glue doesn’t peel off and harden after being washed?
【Coated fabric】https://www.zuranmianliao.cn/

Coated fabric is a fabric (or non-woven fabric) covered with a layer of polymer or other materials to form a composite of fabric and polymer.

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 uses a certain method (cylindrical 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.

Things to note when washing and ironing this type of fabric:

Coated fabrics are not suitable for dry cleaning, because dry cleaning may cause the coating slurry to dissolve or degreasing and hardening. The best washing method is to wash by hand! It is forbidden to iron directly from the front to avoid the problem of coating melting and adhesion!
【Composite Fabric】
Composite fabrics can be understood as new fabrics in which two (or more) fabrics with different compositions, different tissues or different dyeing and finishing processes are organized together through a special bonding process.

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 fabric is fine, clean, delicate, elegant, and warm, and the fabric has a plump appearance, windproof, and breathable. It has certain waterproof function.
Its main features are warmth and good breathability.
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 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.
Precautions for washing and stain removal:
Composite fabrics are prohibited from high-intensity and long-term dry cleaning, which 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!
