Some fans are asking, what are the differences between polyester, pure cotton, polyester fiber and silk floss? Let me formally explain it to you here.
The first one is polyester fiber. Polyester fiber is a modification of polyester fiber. It improves polyester fiber’s low moisture content, poor air permeability, poor dyeability, and easy pilling and fluffing. Disadvantages such as easy staining. It is a fiber-forming polymer made from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or transesterification and polycondensation reaction. —Polyethylene terephthalate (PET), fiber made by spinning and post-processing.
The advantages are: bright luster, flashing effect, smooth, flat, and good elasticity; anti-wrinkle, no ironing, and good light resistance; after pinching the silk surface with your hands, Release without obvious creases.
Disadvantages are: gloss is not soft enough, air permeability is poor, dyeing is difficult, melting resistance is poor, and holes are easily formed when exposed to soot, sparks, etc.
Polyester is one of the three major synthetic fibers with the simplest craftsmanship and relatively cheap price. It is a chemical fiber clothing fabric that is widely used in daily life. Its biggest advantage is that it has good wrinkle resistance and shape retention, so it is suitable for outerwear, various types of bags, tents and other outdoor products.
The advantages are: high strength, super elasticity close to wool; good heat resistance, light resistance, wear resistance and good chemical resistance.
Disadvantages: poor dyeability, poor melt resistance, poor hygroscopicity and easy pilling and staining. Cotton refers to fabrics produced from cotton as raw material. Generally speaking, pure cotton fabrics have better moisture absorption and heat resistance, and are comfortable to wear. Work clothes in some industries that require high hygroscopicity of clothing can be processed with pure cotton fabrics. For example, summer school uniforms, etc.
Polyester can also be called polyester fiber, which is relatively common among synthetic fibers. Its biggest feature is its good elasticity, which is better than any fiber, so polyester fabrics are smooth and stiff. It is wide, not easily deformed, and has the reputation of being easy to iron.
Polyester also has relatively good strength and wear resistance. Fabrics woven from it are 3-4 times higher than other fibers. In addition, its heat resistance is also very good. However, the internal molecules of polyester are tightly arranged and lack a hydrophilic structure between the molecules. Therefore, the hygroscopicity is particularly poor. Clothes made of polyester fabrics feel stuffy and airtight when worn on the body. And it’s also very easy to pill.
As for silk floss, the advantages are: cotton fiber has better hygroscopicity, higher elasticity, heat and alkali resistance, hygienic and healthy; disadvantages: easy to wrinkle, easy to shrink, easy to wear. It is deformed, easy to stick to wool and is especially afraid of acid. When concentrated sulfuric acid contaminates cotton, the cotton will be burned into holes. Silk floss: In a narrow sense, silk floss refers to natural silk cotton.
In a broad sense, silk cotton refers to silk-like fabrics, such as hollow cotton, mixed silk cotton, imitation silk cotton, seven-hole cotton and other materials. Silk floss comes from the floating threads on the surface of foot cocoons and cocoon shells. It is refined and processed to dissolve the sericin and loosen the fibers.
It has good warmth retention properties and is often used as a filling for quilts or clothes. Silk floss is soft against the skin, warm in winter and cool in summer, has no irritating effect on the skin, can promote sleep, is antibacterial, moisture-wicking and other properties.
And there are two main types of silk floss: natural silk floss and silk floss-like fabrics. Nowadays, most of the silk floss-like fabrics used on the market are hollow cotton, seven Hole cotton, silk-like cotton, spray-coated cotton, etc. It’s considered chemical fiber. Silk floss has relatively high warmth retention, and is often used as quilt batting and clothing batting. Silk floss is relatively soft against the skin, warm in winter and cool in summer, without any irritation to the skin, and has antibacterial and sweat-absorbing effects. Silk wool is not easy to shrink or fade. It is also more wear-resistant, has a higher heat dissipation capacity, and has a brighter color. Silk floss not only has the natural characteristics of raw cotton, but also has the luster of silk.
