Textile knowledge: the fundamental difference between cotton-polyester and polyester-cotton

Polyester-cotton refers to the polyester-cotton blended fabric, which is made of polyester as the main component, and the polyester-cotton blended fabric is made of polyester as the main component, using 65%-67% polyester and 33%-35% cotton blended yarn. , Polyester cotton cloth, commonly known as cotton, is indeed good.

Features of polyester cotton:

It not only highlights the style of polyester but also has the advantages of cotton fabric. It has good elasticity and abrasion resistance in dry and wet conditions, stable size, low shrinkage, and has the characteristics of being tall and straight, not easy to wrinkle, easy to wash, and quick-drying. Do not use high-temperature ironing and boiling water soaking.

Disadvantages of polyester cotton:

The polyester fiber in polyester-cotton is a hydrophobic fiber. It has a strong affinity for oil stains and is easy to absorb oil stains. It is also easy to generate static electricity and attract dust during the wearing process. It is difficult to wash, and it cannot be ironed with high temperature and soaked in boiling water.

Classification of polyester cotton:

Customers who often buy shirts know that the fabrics of many shirts are marked with polyester or cotton. "Polyester cotton" and "cotton polyester", the order of the two words is changed into two different fabrics. "Polyester-cotton" fabric means that the composition of polyester is more than 60%, and the composition of cotton is less than 40%; "cotton-poly" is just the opposite, meaning that the composition of the surface is more than 60%, and the composition of polyester is less than 40%.

So, which of the two fabrics, "poly-cotton" and "cotton-poly" is better? This depends on the preferences and actual needs of customers. In other words, if you want the polyester fabric of a shirt to have more characteristics, choose "polyester cotton", and if you want more characteristics, choose "cotton polyester".

Polyester cotton is a mixture of polyester and cotton, and it feels less comfortable than cotton. Wearing and not as good as cotton to absorb sweat. Polyester is a high-yield variety of synthetic fibers. Polyester has many trade names, "Polyester" is our country's trade name. The chemical name is polyethylene terephthalate, which is usually formed by the polymerization of chemicals, so the scientific name often carries "poly". Polyester is also called polyester. Structure and performance: The structure shape is determined by the spinneret hole. The cross-section of conventional polyester is round and has no cavity. Changing the cross-sectional shape of the fiber can produce special-shaped fibers. Improve brightness and cohesion. Fiber macromolecules have high crystallinity and high orientation, so the fiber has high strength (20 times that of viscose fiber) and good abrasion resistance. Good elasticity, not easy to wrinkle, stiff and good shape retention, good light resistance and heat resistance, quick-drying after washing, no ironing, good wash and wear performance.

Polyester is a chemical fiber fabric, which is not easy to wick away perspiration. It feels thorny to the touch, it is easy to generate static electricity, and it looks bright when tilted.
　
Polyester-cotton blended fabric is a variety developed in my country in the early 1960s. The fiber has the characteristics of stiff, smooth, quick-drying, and durable, and is deeply loved by consumers. At present, the blended varieties have developed from the original ratio of 65% polyester to 35% cotton to 65:35, 55:45, 50:50, 20:80 and other different ratios of blended fabrics. The purpose is to adapt to different levels. Consumer demand.
