Polyester fiber, also known as polyester, many people have heard of this fabric, but not many people know about it. In most people’s minds, polyester fiber (polyester) is chemical fiber, synonymous with inferior and low quality. The day before yesterday, a celebrity brand was criticized by the entire Internet for selling clothes made of polyester fiber for nearly 1,000 yuan.

However, looking at the bedding industry and clothing industry, we can also find that many big brands use this material. So what exactly is polyester fiber? Is it good or bad?

What material is polyester fiber?

Polyester fiber is a synthetic fiber formed by the polycondensation of organic dibasic acid and dihydric alcohol. Polyester fiber is a common international name. In China, people habitually call it polyester. In the 1980s, the “Chenliang” used was polyester.

Polyester fiber is a general term for synthetic fibers whose raw material is polyester. Depending on the differences in some synthetic raw materials and processing techniques, it can also be subdivided into different fibers. Common ones include polyethylene terephthalate fiber (PET), polybutylene terephthalate fiber (PBT), polypropylene terephthalate fiber.� fiber (PTT), and various modified polyethylene terephthalate fibers (PET). These fibers are gradually upgraded in terms of wear resistance, water absorption, elasticity and other properties.

The most common and most widely used fiber in life is polyethylene terephthalate fiber (PET). When people mention polyester fiber, they usually mean It refers to polyethylene terephthalate fiber, which is what we often call polyester. Modified polyethylene terephthalate fiber refers to a fiber that has been treated with specific technologies and has significantly improved moisture absorption and moisture removal effects. We collectively call it modified polyester fiber.

Advantages and disadvantages of polyester fiber

Advantages of polyester fiber

1. Solid and durable: Poly Ester fiber has high strength, good heat resistance, strong light resistance, acid and alkali resistance, good color fastness, washability and light resistance, not easy to fade, and durable.

2. Easy to wash Quick drying:The moisture regain of polyester fiber material is 0.4%-0.5%. It absorbs less water after being put into the water and has a low moisture content. Therefore, it dries much easier than natural fibers such as cotton after washing.

3. Not easy to breed Bacteria and mites: Polyester fiber has low moisture content and lacks a growth environment for bacteria and mites, so it can effectively inhibit the reproduction of bacteria and mites.

4. Stability Strong:The elasticity of polyester fiber is close to that of wool, and it can be almost restored after stretching and compression. Therefore, when it is woven as a fabric, the fabric is stiff, wrinkle-resistant, and not easily deformed. When used as a filler, it can quickly restore fluffiness and warmth after vacuum compression. Effect.

5. Affordable price :The fiber has not been modified and excluding the influence of brand premium, polyester fiber is relatively cheap overall. A four-piece bed set can usually be purchased for less than 100 yuan, and a quilt can usually be purchased for about 200 yuan.

Disadvantages of polyester

1. Poor moisture absorption and breathability:Polyester fiber has small pores and It has low moisture regain and is not hydrophilic. Therefore, when using bedding made of this material, it will give people a feeling that it is not skin-friendly, not close to the body, stuffy and not breathable.

2. Easy to start Static electricity:Because fiber has poor water absorption and low moisture content, this material is prone to generate static electricity and absorb dust during friction, which affects the user experience.

However, after polyester fiber has been treated with certain technologies, such as 3M moisture absorption technology, it can also achieve good moisture absorption and breathability effects, improving Comfort of use.

The principle of 3M moisture absorption technology is to increase the micropores and surface grooves that communicate between the inside and outside of the fibril, making it easy for moisture to enter the fiber, thereby improving the moisture absorption of the fiber. efficiency. At the same time, because the grooves on the fiber surface have been opened, moisture can be transferred to the surface of the fabric and dispersed, allowing the moisture in the fabric to evaporate quickly, keeping it dry and non-sticky.

Is 100% polyester good?

The quality of a material has little to do with its low cost. As we mentioned above, polyester fiber has high plasticity, wear resistance, sun resistance, washability, durability, strong stability, and good stiffness. Therefore, many big-name products such as coats, suits, skirts, and trousers use polyester fiber. Ester fiber. After being processed through different processes, polyester fiber can also have a soft or silky luster and smooth feel.

After modification to improve the water absorption and breathability of the fiber, it absorbs moisture, dries easily, and is refreshing and cool, so sports brand clothing and summer quilts will also use it. And after modification, the cost of polyester fiber is no less than that of natural fibers such as pure cotton.

In the bedding industry, polyester fiber is also often used in quilts and quilt core fabrics. Filled as a quilt core, it is light, soft, fluffy and warm, and is affordable and suitable for most families, especially in the humid and cold South. When used as a quilt surface material, it is strong and durable, so you don’t have to worry about the quilt easily wearing out, running down, etc. .

So, polyester fiber does not mean inferior and cheap. Depending on its performance and use, it can exert different advantages. However, if it is a four-piece set, underwear, home clothes, etc. that are used close to the body, it is recommended to choose pure cotton, modal, viscose and other materials with higher moisture absorption rate and closer fit, which will be more comfortable.
