Properties of Polyester fiber are as follows. We measure it by categorizing into two way. One is Physical Property and another is chemical property. Here we are describing all properties of polyester.
Properties of Polyester Fiber
-
Physical Properties
- Shape and look : These are typically spherical and uniform. it is partly clear and white to slightly off -white in color.
- Strength : The polyesters are normally stronger. we use it for industrial purpose.
- Elasticity : Polyester fibers don’t have high degree of snap. Normally polyester has high degree of stretch resistance. It suggests that polyester materials aren’t seemingly to stretch out of form too simply.
- Resilience : Polyester has high degree of resilience. It resist wrinkle while it is wet.
- Drapability : Materials of polyester filament have satisfactory draping quality. The small stuff of polyester is versatile and softer. Thereafter it has a good draping quality.
- Heat conduction : Polyester filament are sensible conductors of warmth. It doesn’t offer larger insulation within the yarns and materials. The rationale for attire larger heat of polyester is low permeability.
- Absorbency : It has low amount of absorbency which is one of the smallest amount absorbent fibers. This low permeability has necessary advantages that they’re going to dry in no time. Thy are well enough to water repellent functions, like rain wear and they don’t stain simply.
- Dimensional Stability : Polyester fiber has a good dimensional stability. If the polyester is correctly heat set, it’ll not shrink, nor stretch once subjected to boiling water, boiling cleanup solvents or ironing temperatures that are less than heat setting
- Shrinkage : It has a good shrinkage property. It shrinks the maximum amount as twenty the longest enduring wet-finishing operations and that they heat set in later treatments. They need glorious dimensional stability.
- Cleanliness and Wash-ability : Since polyester fibers are typically swish, has low permeability, several stains lie on surface, and simply wash out, by hand or machine however oil stains to get rid of.

Chemical Properties
- Reaction to Alkalies : At temperature, polyesters has sensible resistance to weak alkalies and honest resistance to robust alkali. It reduces with increase in temperature and alkalies concentration.
- Reaction to Acids : Polyester has sensible resistance to mineral and organic acids relying on kinds. Extreme solution degrade at high temperature.
- Effects of Bleaches : We can bleach a polyester material safely. As we know that polyesters have sensible resistance to deterioration of unit bleaches. If the polyester have optical brightener, bleaching isn’t necessary.
- Effect of Heat: At temperature ironing is necessary. It gets sticky at 4400Â F.
- Effect of sunshine : Polyester has sensible resistance to degradation of daylight. Over prolonged use, gradual deterioration of fiber happens.
- Affinity for Dyes : Polyesters artificial with applicable disperse, developed dyes at high temperatures manufacturing an honest vary of shades and color fastness.
- Resistance to Perspiration : Polyesters does not loose strength contacting with either acid or alkali perspiration.
Polyester Blends : Polyester cotton mix, polyester wool mix, polyester material, polyester silk mix, polyacetate mix, , polyester and nylon ar some common blends.
