Terylene is a synthetic polyester fibre produced by polymerizing ethylene glycol and terephthelic acid which is obtained from petroleum. The fibre was first created in 1941 by chemist J R WHINFIELD of Accrington who sold the patent rights to the chemical company ICI. In America, it is produced as the name “Dacron”. It has created as a “Ready Market” as “made-Up” garments as they will take permanent pleats when subjected to the correct temperature, at the time of manufacturing. The major disadvantage is that they are yet not easily procurable by the by the yard. Since the terylene fibre can be chemically reproduced, thus the manufacturers have a greater control on the industry in these consequence which emphasis that “TERYLENE” can be produced as per the requirement in future.

Properties and Uses of Terylene


Terylene is extensively used in textile industry to make hard wear clothes like sarees , taoestry and dress material. Terylene is made by a process of polymerizing ethylene glycol and terepthalic acid. It is also mixed with natural fibre like cotton and wool to make more variety of clothes.

Properties and Use of Terylene are mention below:

Properties of Terylene:

  • Terylene is a very strong fibre and will suffer very little loss in strength when wet.
  • It is elastic in nature and posses the property of resist creasing.
  • IT can be set into permanent pleats when subjected to the correct temperature, at the time of manufacturing.
  • Terylene is easily washed and dries quickly.
  • It is non-injured by acidic substances when used in the moderation process. Neither bleaches or dry cleaning agents can harm it.

The dye uptake of Terylene subjected to dry and live steam heat can be characterized by a constant defined as the uptake decided by the square root of time (A/t), as in equation for diffusion.This constant is found to decrease to a minimum with increase in temperature of dry heating and then to increase to a value greater than that for the unheated yarn at high temperature of preheating.

Steam preheating also effects the constant and , at the higher temperature of steam heating, shows similar tendencies to those found for dry heat but to less extent. These result were obtained under the condition that allow free shrinkage during dyeing.  However, if dyeing is carried out with the material under tension, although the general tendency is the same, the dye-uptake constant is greater than that for the corresponding samples dyed in the absence of tension and is greater than that of the unheated yarn for most of the samples.

Measurement of parameters indicative of structural changes in fibres, e.g. moisture regain, density, X-ray orientation shows that these variations in dyeing properties cannot be express on the basis of the fringe-mi-cellar n/w theory of structure. An explanation in advance form which postulates a structure with rod-like morphological units separated by narrow voids, the size, amount and virtuosity of which govern the accessibility of the dye.

Use of Terylene:

  • Terylene is mainly used in making plastic bottles and clothing.
  • It is also used for making-
  1. Terylene fiber is used as polyester tricot knit as a fashion garments fabric.
  2. Used for the laundry usage as a automatic clothing vacuum packaging machine.
  3. It is used to make nonwoven needle punched carpet particularly for the exhibition use.

Question & Answer on Properties and Use of Terylene

1. What is terylene??

ANSWER: Terylene is a synthetic polyester fibre or fabric based on the terephthalic acid , charectrized by the lightness and crease resistance and used for clothing , sheets , ropes , sails.

2. What is terylene fabric? 

ANSWER: Terylene fabric is a synthetic polyester fibre which is based on the properties of terephthalic acid. It is characterised by weightlessness and crease resistance. Terylene is mostly used for clothing, ropes, sheets, sails and many others. The name ‘terylene fabric’ may also refer to any large class of synthetic fabric.

3. How terylene is made??

ANSWER : Synthetic polyester fibre “terylene” is produced by polymerizing acid named as terephthelic acid and ethylene glycol at a suitable temperature. The fibre was first discovered by two chemists Lanca and Shire in 1941.

4. What are the properties of terylene ?


  • Fibre are strong and elastic in nature.
  • They absorb very little water and hence dry quickly.
  • They are stable at high temperature.
  • They are insoluble in most organic solvents, and resistant to acid and cold alkalies.
  • They are crease resistant hence require very less ironing.
  • They are resistant to friction.

5. What are the use of terylene??

ANSWER: Use of Terylene are as follows:

  1. Hoses
  2. Ropes
  3. Nets
  4. Thread
  5. Raincoats
  6. Fleece jackets
  7. Clothing
  8. Medical textiles

Although Properties and Use of Terylene will not change but questions on Properties and Use of Terylene will change from company to company and exam to exam so we would suggest you to put your questions in brief at bottom of this page in comment section , if you are planning to appear for any exam so that we may suggest you right question at right time. which may be suitable for that exam.
