Blanket fabric: the difference between polyester and acrylic
Polyester: It is an important variety of synthetic fibers and is the trade name of polyester fibers in my country.
The properties of polyester:
1. Polyester fabric has high strength and elastic recovery ability. As a result, it is durable, wrinkle-resistant, and non-iron.
2. Polyester fabrics have poor hygroscopicity, feel sultry when wearing, and are easy to carry static electricity and stain dust, which affects the appearance and comfort. However, it is very easy to dry after washing, and the wet strength hardly decreases, and it does not deform. It has a good wash and wears performance.
3. Polyester is the best heat-resistant fabric among synthetic fabrics. It has thermoplastic properties and can be made into pleated skirts with long-lasting pleats. At the same time, polyester fabric has poor melting resistance, and it is easy to form holes when encountering soot, sparks, etc. Therefore, try to avoid contact with cigarette butts, sparks, etc. when wearing.
4. The light fastness of polyester fabric is better, except that it is worse than acrylic fiber, its light fastness is better than that of natural fiber fabric. Especially the light fastness behind the glass is very good, almost on par with acrylic.
5. Polyester fabrics have good resistance to various chemicals. Acids and alkalis are not very damaging to them, and they are not afraid of mold or insects.
Acrylic fiber (bulky and lightfast): It is the trade name of polyacrylonitrile fiber in my country. Acrylic fiber has excellent properties. Because its properties are close to wool, it is called "synthetic wool".
Properties and uses of acrylic fibers:
Elasticity: Its elasticity is better, second only to polyester, and about 2 times higher than nylon. Has better shape retention.
Strength: Although the strength of the acrylic fiber is not as good as that of polyester and nylon, it is 1 to 2.5 times higher than wool.
Heat resistance: The softening temperature of the fiber is 190-230C, second only to polyester among synthetic fibers.
Lightfastness: The lightfastness of acrylic is the best of all synthetic fibers for one year of open-air exposure, with only a 20% drop in strength.
