Polyester yarn refers to yarn spun from polyester as raw material, and polyester is a kind of fiber made by spinning a polymer.
At present, it mostly refers to fibers produced with ethylene phthalate as raw material, which is abbreviated as "polyethylene terephthalate" according to the English name of the raw material, abbreviated as "PET" fiber. Commonly known as polyester in our country.
Pure polyester yarn is made of polyester staple fiber by warp spinning, and the staple fiber has different categories. From the length, it can be divided into cotton fiber, the length is about 37 mm, and there are medium and long fibers, the length is 51 mm-57 mm. mm, with hairy fibers, 75 mm-105 mm in length.
In terms of thickness, there are fine denier fibers, which are around 1.5D, coarse denier fibers around 5D, and intermediate 3D fibers. Of course, there are finer fibers such as 1D, and even ultra-fine fibers such as 0.1-0.5D.
The yarn is as thin as 50 to 60, and it is best to use fine denier fibers to spin it, so that it is easy to spin evenly, with good evenness and less hairiness. If the fiber is longer, it can increase the cohesion and the strength is better;
The spun yarn has a fine hand, on the contrary, the coarse denier yarn has a rough hand and a better wool feel.
When spinning polyester staple fiber yarn, it is necessary to know how thick the fiber is, how long it is, and generally know where the staple fiber is produced.

Full-gloss polyester yarn: The surface of the polyester fiber is smooth, and the surface of the woven fabric has a strong luster.
Semi-gloss polyester yarn: The fabric woven with full-gloss polyester yarn is chemically reduced by the dyeing factory, which is to take advantage of the poor resistance of polyester material to strong alkali, and treat it with sodium hydroxide to cause micro cracks on the surface of polyester fiber. , resulting in a matting effect. The semi-gloss polyester fabric has a noble and elegant appearance and is welcomed by the market.
Semi-gloss polyester yarn can also be understood as cracking or roughening the fiber surface by various physical/chemical methods in the fiber manufacturing process, and the woven fabric has the same effect as the above-mentioned fabric weight reduction treatment.
Polyester yarn is a kind of raw material for weaving. The raw materials of weaving are collectively called yarn or silk, corresponding to cotton yarn, artificial yarn (silk), nylon yarn (silk), wool yarn, hemp yarn and so on.
Polyester yarn is a kind of synthetic fiber, scientific name polyethylene terephthalate, English polyester, its characteristics are almost non-hygroscopic (moisture regain 0.4%, cotton yarn has 8.5%), the woven fabric is easy to wash and dry, crisp Firm, not easy to wrinkle, the disadvantage is poor comfort.
