The properties of polyester fibers are directly related to the polymer properties (including the molecular weight), especially the spinning and post-processing conditions.
(1) appearance: polyester fiber is generally milky white, and different types of products can be produced according to the needs of users.In the process of production, pure white fiber can be made by adding whitening agent, and colored fiber can be made by dyeing various colors.As a result of the fiber section shape is different, the vision feels different luster.With the addition of matting agent (carbon dioxide drill) with different amounts, can be prepared to meet the needs of the user of different gloss fiber, forming super light fiber, light fiber, half matting fiber, full matting fiber.
(2) density: polyester fiber density varies with its crystallinity and orientation, generally in 1.38 ~ 1.40 g/cm 3.When hollow fiber is prepared, its density can be reduced to 0.6 ~ 1.2 g/cm 3, which is lighter than wool and very warm.This fiber can be used in cotton fabric or quilt sheet, pillow, toy filler.
(3) hygroscopicity: the moisture regain rate of polyester fiber is very low. When the relative humidity is 65%, the hygroscopicity is 0.4%.0.5%, even when the relative humidity is at 100%, the moisture absorption rate is only 0.6%.0.8%, so polyester fabric has the characteristics of easy washing and quick drying.
(4) heat resistance: the softening point of polyester fiber is 230-240 ℃, the melting point is x5 plus Y, and the phase of other fibers is Lb. The heat resistance of polyester fiber is better under the heat condition.(5) light resistance: under the ultraviolet irradiation with the wavelength of 315flm, the polyester fiber produces the phenomenon of molecular fracture, the fiber strength decreases, and its light resistance is higher than that of polyamide and lower than that of acrylic.
(6) electrical properties: polyester fiber in the dry state, has a good electrical insulation, so in the processing and clothing, because of friction and easy to produce static electricity, easy to absorb dust, which is a disadvantage of polyester fiber.
(7) chemical properties: polyester fiber has a certain stability to acid and alkali at room temperature, but corrosion resistance decreases with temperature rise.It has strong antioxidant ability to some oxidants.
(8) antibacterial property: polyester fiber is usually not by microbial erosion, with antibacterial property, so the fabric will not be moth decay.
