Short fiber strength is 2.6 ~ 5.7 cN/dtex, high strength fiber is 5.6 ~ 8.0 cN/dtex.
Due to its low hygroscopicity, its wet strength is basically the same as that of dry state.
The impact strength is four times higher than nylon and 20 times higher than viscose fiber.
The elastic approach to wool is almost completely restored when it is 5 to 6 percent elongated.
Wrinkling resistance is more than other fiber, that is, the fabric is not creased, the dimensional stability is good.
Elastic modulus is 22 ~ 141cN/dtex, 2 ~ 3 times higher than nylon.
Polyester fabric has a high strength and elastic resilience. Therefore, it is fast and durable.
Heat resistance dacron is made from melt spinning, and the formed fiber can be heated and melted again, which belongs to thermoplastic fiber.
The melting point of dacron is relatively high, and the specific heat capacity and thermal conductivity are small, so the heat resistance and adiabatic of polyester fiber are higher.
It's the best synthetic fiber.
Good thermal plasticity and poor fusibility.
Because the polyester surface is smooth and the internal molecules are closely aligned, polyester is the best material for heat resistance in synthetic fiber fabric. It has thermoplastic, can make pleated skirt, and pleating is durable.
At the same time, the anti - melt property of polyester fabric is poor, and it is easy to form holes such as soot and Mars.
Therefore, should try to avoid contact with cigarette end, spark, etc.
Good wear resistance.
Wear resistance second only to the best nylon, better than other natural fibers and synthetic fibers.
Good light resistance.
Light resistance is second only to acrylic.
The light resistance of polyester fabric is better than that of acrylic. It is superior to natural fiber fabric.
Especially behind the glass, the suntan ability is good, almost equal to the acrylic.
Bleaching agent, oxidizer, hydrocarbon, ketone, petroleum products and inorganic acid.
The alkali is not afraid of mold, but it can be decomposed.
It also has strong anti-acid and alkaline resistance to uv radiation
The dyeing sex is poor, but the color fastness is good, not easy to fade.
Because there is no specific dye group on the polyester molecular chain, and the polarity is small, the dyeing is more difficult, the stain is poor, and the dye molecules are not easy to get into the fiber.
9. The moisture absorption is poor, the clothes have a sultry feeling, and easy to bring static, dirt and dirt, affect the beauty and comfort.
However, it is easy to dry after washing, and the wet strength is hardly reduced, not deformed, and has good washing ability.
Woven from ordinary polyester filament fabric, the garment with performance had good strength, smooth crisp, easy to wash the advantages of fast drying, but there are hard, soft tactility, poor luster, and poor permeability, hygroscopicity, shortcomings.
If compared with the silk fabric, the gap is larger, so the silk thread structure is the first thing to imitate silk, to eliminate the disadvantage of the poor performance.
