Polyester is a common representative of the class of polyesters. This is a synthetic fiber made of molten polyethylene terephthalate.
What is polyester
Research on it was started in 1935 in the UK, it was registered in 1945. In the former USSR it was called lavsan (at the place of research in the laboratory of the Academy of Sciences). What is polyester? Materials of this group are used in the production of food films, plastics. This is a common trend in the polymer industry. In Russia, they are used mainly as blanks of various types, from which all kinds of plastic containers and containers are made. To a lesser extent is used for the manufacture of fabric, film and molding of various products. In other countries, the situation is the opposite: most polyethylene terephthalates are used in the production of threads and fibers.
Structure
What is polyester? Do you know what its composition is? Polyester properties are unique. That is why it is so appreciated. 100 polyester retains very strong heat resistance. It has high elasticity and low hygroscopicity. This property is perfect for use in light industry, because such products perfectly retain their appearance and do not change shape. When using, it is noted that polyester is resistant to fading, mold, it is not even afraid of moths. Bleaching is not allowed.
Mix with other fibers
To increase the strength of finished products, giving them antistatic properties, polyester is used with other natural fibers. This combination significantly increases the quality and consumer demand for fabrics for sewing all types of clothes (from coats, jackets, suits and to linen). Given that polyester is soft and dries quickly, it is often combined with viscose and cotton. Polyester fibers are very similar to wool, perfectly imitate the texture of natural fiber. Used in some cases, a mixture with polyamide. From various additives, weaving patterns, the size of the fibers used, polyester can change its texture, appearance, be dull or shiny.
Application area
What is polyester? He opens a group of synthetic fabrics. Very popular and often used by designers. Its resistance to light, high strength and the ability to maintain its shape for a long time will always be in price among leading fashion brands. The positive properties include the following:
- Thin fabrics, very quick drying.
- It keeps and fits well, does not wrinkle. Keep in mind that during overheating, wrinkles may appear on the fabric, which are not so easy to straighten.
- Not afraid of sunlight, does not fade, suitable for sewing textile products. Such products, after many years of use, retain their original brightness.
- Easy to clean, stain resistant, easy to clean.
- Fabrics made of polyester are not afraid of weathering, ideal for sewing sports equipment, coats, jackets.
- When sewing in the products perfectly pleated pleats and corrugations.
- Fabrics do not stretch and do not sit, are resistant to abrasion.
The negative properties of polyester are as follows:
- Low hygroscopicity.
- It is difficult to stain.
- Has increased rigidity, it is electrified.
