[Dry information] Application of PUR glue in Composite fabrics and electronic products
【Coated fabric】
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 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 fabric It is not suitable for dry cleaning, because dry cleaning 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 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 use “new synthetic fiber” high technology and new materials, and have many excellent properties (compared with ordinary synthetic fibers), such as fabric performance Clean, refined, elegant, and warm, the fabric 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.
Precautions for washing and stain removal:
Composite fabrics are prohibited from high-intensity and long-term dry cleaning, which may cause the composite fabrics 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!
