What are polyester fibers and washing methods?
Polyesters come from Phthalic Acid and two lactone, or glycol, usually ethylene glycol, esterified and condensed. In fact, internal transesterification is carried out with two benzoic acid, two methyl ester. When the methanol recovery, the molten polymer will stretch forming fiber. In order to obtain high transparency and luster fibers, some monomers are added to the melt. In order to obtain low crystallinity and low strength products, part of stretch yarn, and then further stretch, textile and plastic. Polyester fiber near the glass transition temperatures near the stretch and textile can get very high degree of crystallinity, the high crystallinity and leads to high strength, resulting in two small molecular dimer or very fine thread. The surface of polyester fiber is hydrophobic.In further treatment, the crystallinity of the polymer is also important, and any heating near the glass temperature will reduce the crystallinity, thereby reducing the mechanical properties of the fiber.
Wash polyester / cotton blended fabric available with cotton detergent. In order to remove oil stains, you should first select formulations containing high HLB values, such as LAS. If it doesn't work, it can be treated with alcohol. But it is difficult to remove the oil pollution on polyester fiber for a long time.For polyester fiber / wool washing, we should pay attention to the taboo conditions of wool washing, especially should avoid high alkaline, it is appropriate to choose the appropriate wetting agent, phosphate and silicate as additives. Lay the foundation for future dyeing and finishing.
Like other synthetic fibers, polyester fibers do not carry dirt as easily as natural fibers because of processing methods. Its hydrophobic properties on the surface reject hydrophilic dirt, but oil stains can easily cause spots, or even penetrate into the interior of the fiber, making it time and heat to wash them away. The removal of dye staining on the polyester fiber, are the main factors to consider when designing the detergent. Polyester and cotton blend very well, usually polyester ratio of 40%~60%, and wool and wool blend ratio is slightly smaller. Natural fibers have a good feel and comfort, and moisture absorption, but polyester fiber is not. The blend is made from ready made blends rather than monofilament.Like other synthetic fibers, polyester fibers do not require heavy-duty detergents. Its hydrophobic properties have strong resistance to water solubility, whether it is acid or alkali. Pay attention to the lipophilicity of polyester fiber when designing detergent.
1., should be washed with cold water or warm water, do not force to screw;2. times dry shade, not exposure, so as not to rimpled;3., ironing should be put on a damp cloth, the temperature can not be too high, dark clothing, underwear best ironing the reverse side.
Polyester fiber synthetic fiber polyester (polyester fibre) by organic acid and diol which is prepared by spinning the. A large number of industrially produced polyester fibers are made from polyethylene terephthalate, a Chinese product called polyester. It is the largest variety of synthetic fiber at present.
