The polyester and all its characteristics

Polyester is a resistant and non-wrinkable fiber developed in 1941. It is the most used synthetic fiber, and very often it is mixed with other fibers to reduce wrinkles, soften the touch and get the fabric to dry faster. Polyester was introduced in the United States under the name of Dralón. This fiber is manufactured from chemical products derived from petroleum or natural gas and requires the use of non-renewable resources and large amounts of water, for the cooling process. However, polyester can be considered a chemical fabric that respects the environment; if it is not mixed, it can be melted and recycled. It can also be manufactured from recycled plastic bottles. JIXING FIBER is role model of polyester fiber industry at the present. They mainly manufacture polyester resin which is made by PTA and MEG mixture, and Pet Flakes from water bottle. They also have wadding factory, down coat garment factory, pillow factory, fiberfill factory, cushion factory, stuffy toys factory. With inspired by their industry I thought I’ll write an article about types of polyester fiber and its characteristics. Origin of the polyester In the thirties, the first polyester fiber, continuous filament, produced from dicarboxylic acids called Terylene was produced in England; After World War II, the German firm Hoechst began producing a polyester with the name Trevira. In 1946 Du Pont acquired the exclusive to manufacture polyester in the United States, knowing in that country with the name of Dacron, and launched in 1951. During these years, Du Pont, sought to multiply the technical properties of polyester, texture filaments and creating synthetic naps (fiberfil for fillings) that, superimposing them, were used for sleeping bags and anoraks, since they have a better result than the natural feather. Obtaining the polyester Polyesters are polymers, in the form of fibers, in the '70s to make the clothes used in dance confectionery. But since then, the nations of the world have struggled to develop more profitable applications for polyester, such as unbreakable plastic bottles. As can be seen, the polyesters can be both plastic and fiber. Another place where you find polyester is in the balloons. Products like these, made of two kinds of raw material, are called composites. A special family of polyesters are polycarbonates.

Types of Polyester Fiber

The polyester fibers are commonly accessible in two varieties – PET (Polyethylene Terephthalate) and PCDT (Poly-1, 4-Cyclohexylene-Dimethylene Trephthalate). PET is the most well-known production. It is stronger than PCDT, while PCDT has greater versatility and flexibility. PET can be utilized alone or mixed with different textures for making wrinkle free and stain safe attire that can hold its shape. PCDT is more suitable for heavier applications, for example, draperies and furniture covers. Alterations can be presented in every one of these assortments for getting explicit properties.

PET Polyester

For manufacturing PET Polyester, the fundamental crude material is ethylene, gotten from oil. It is oxidized to create a glycol monomer dihydric alcohol which is additionally joined with another monomer, terephthalic acid at a high temperature in a vacuum. Polymerization, the substance procedure that creates the completed polyester, is finished with the help of impetuses. The dismal liquid polyester at that point streams from a space in a vessel on to a casting wheel and takes shape of a ribbon as it cools to hardness. The polymer hence delivered is then cut into extremely little chips, dried to expel all dampness and mixed to make it uniform for preparing it for turning into yarn.

PCDT Polyester

This variety of polyester is made by consolidating terephthalic acid with 1, 4-cyclohexane-dimethanol to frame poly-1, 4-cyclohexylene-dimethylene terephthalate or the PCDT Polyester. Concerning PET Polyester, PCDT is prepared for melt spinning.
