When purchasing, some materials often attract the attention of some friends, such as polyester and polyester fiber. Friends who know it well will say that they are the same material. Friends who are not sure about it will say that they are the same material. Wondering why the same material has different names?

Is there any difference between polyester and polyester fiber?

Divided by name

Polyester fiber is an internationally common name, mainly famous for its earliest production name, and now it has become an internationally common name;

Polyester is the Chinese name, and in China polyester fiber is usually polyester.

From this point it is clear that there is no difference between them.

Ju Introduction to esters

Usually refers to polymer compounds obtained by the condensation of dibasic acids and diols, including all molecular chains containing more than 85% terephthalene Fibers composed of linear macromolecules of acid glycol esters.

There are many varieties of polyester fibers. Three types are given in GB/T4146.1-2009, namely polyethylene terephthalate (PET) fiber, polybutylene terephthalate (PBT) fiber and polytrimethylene terephthalate (PTT) fiber. Among them, the trade name of PET fiber in my country is polyester. It can be seen that polyester is only a type of polyester fiber. Due to its easy availability of raw materials and excellent performance, polyester has become the fiber with the largest output and the most widely used among chemical fibers. It is precisely because of this that people mistakenly think that polyester fiber is polyester. However, in recent years, with the With the improvement of fiber production technology, polyester fiber has added two new members, PBT and PTT.

PTT fiber has the characteristics of both polyester and nylon. It is easy to wash, quick-drying, has good elastic recovery, and has good wear resistance and stretchability. Resilient, more suitable for making composite fibers, elastic fabrics, carpets and other materials. In addition to the advantages of polyester, PBT fiber also has better dyeing properties and has become one of the promising differentiated fibers in the field of synthetic fibers. In addition, it also has good aging resistance, chemical reactivity resistance and heat resistance. properties, making it widely used in engineering plastics, home appliance casings and other fields. The emergence of these two new types of polyester fibers not only breaks the dominance of polyester fiber, but may even replace it to a certain extent.

With the emergence of PTT fiber and PBT fiber, polyester fiber is no longer exclusive to polyester. However, in actual detection, since these three types of fibers are difficult to distinguish through ordinary methods, theoretically, they can be identified through a combination of infrared spectroscopy and melting point methods, but there are also difficulties in the identification process. Therefore, according to the standard GB/T

4146.1-2009, under normal circumstances, a “polyester fiber” report will be issued. Only when the client explicitly requests it and the sample can be determined to be “polyethylene terephthalate (PET)”, the testing agency can issue a report. “Polyester”.

Introduction to polyester

Polyester (also commonly known as “Qianliang”). Polyester is the simplest of the three major synthetic fibers and its price is relatively cheap. In addition, it is durable, elastic, not easily deformed, and>It feels stuffy when worn, and is prone to static electricity, dust, and pilling.

10.Good quick drying, has good washable and wearable performance.

Polyester type:

1. Polyester imitation silk fabric, a polyester fabric with a silk appearance style woven from round, special-shaped cross-section polyester filament or short fiber yarn, anti-wrinkle It is very popular among consumers due to its advantages such as no need to iron. These varieties have the elegant drape, smoothness, softness and pleasingness of silk fabrics. At the same time, they have the stiffness, wear resistance, easy washing and ironing-free of polyester fabrics. They are also low in price. The only drawback is that these fabrics have poor moisture absorption and breathability, making them difficult to wear. Not too cool.

2. Polyester wool-like fabric, made of polyester filament such as polyester elastic yarn, polyester network yarn or various special-shaped cross-section polyester yarn, or medium and long polyester short fiber Fabrics with a woolen style that are blended with medium-length viscose or medium-length acrylic and woven into yarn are called worsted wool-like fabrics and medium-length wool-like fabrics respectively, and their prices are lower than similar wool fabric products. It not only has the characteristics of wool, which is plump and fluffy, and has good elasticity, but also has the characteristics of polyester, which is durable, easy to wash and quick-dry, flat and stiff, not easy to deform, not easy to fluff, and not easy to pilling.

3.Polyester linen-like fabric, made of polyester or polyester/viscose strong twisted yarn, woven into plain or convex weave fabric, with the dry feel and appearance of linen fabric. Not only does it look rough and feel dry, it is also comfortable and cool to wear. Therefore, it is very suitable for the production of summer shirts and skirts.

4.Polyester cotton-like fabric, which has a soft and fluffy feel similar to cotton and hydrophilic and moisture-absorbing characteristics. It also has the wear-resistance, high strength, easy washing and non-toxicity of polyester fabrics. Hot and cheap at the same time. Currently used in bedding, T-shirts, towels, etc.

5.Polyester blended fabric, in addition to weaving pure polyester fabrics, there are also many products that are blended or intertwined with various textile fibers, which make up for the shortcomings of pure polyester fabrics and play a role in Better taking performance.

The above briefly analyzes polyester and polyester fibers and understands their differences. It can be seen that there is no difference in terms of materials. The only difference is the different names. I hope you will no longer be influenced by the names when purchasing in the future. , you can choose the right products according to your needs.
