IS 17263: 2019

In this competitive scenario, it isn't easy to survive in the market without a standard quality and certified product. BIS license may also be required to sell products in the Indian market.

To get BIS certification and produce a standard quality product, the manufacturer must ensure that their product must follow the specified Indian standard.

Let's take a closer look at IS 17263: 2019 for Polyester Staple Fibres.

IS 17263: 2019 covers Polyester Staple Fibres. The Bureau of Indian Standards adopted this Indian Standard after the Textile Division Council approved the draft finalized by the Man-Made Fibres, Cotton, and Their Products Sectional Committee. PSF is a type of polyester fibre that is produced directly from poly terephthalic acid (PTA) and mono ethylene glycol (MEG) or polyester (PET) chips or recycled PET bottle flakes. Virgin PSF is PSF made from PTA and MEG or PET chips. Recycled PSF is PSF made from recycled PET flakes.

This standard specifies requirements for all types of polyester staple fibres (PSF), such as virgin fibres, dope dyed fibres, cationic dyeable fibres, and other polyester specialty fibres, such as spun lace fibres, slick fibres: antimicrobial fibres, nonwoven/filling fibres, flame retardant fibres, siliconized fibres, and micro fibres, and so on, for various end uses. This standard does not cover fibres for use in cement matrices for construction work.

Classification of staple fibre

The manufacturer must declare the classification of staple fibre as described below.

  1. Based on Cross Section, For Example, Circular, Profiled
  2. Based on Cross-Sectional Area, For Example Solid, Hollow
  3. Based on Multi-Component Fibres, For Example, Concentric Cover-Core, Matrix
  4. Based on Fibre Linear Density, For Example, Coarse, medium-fine, fine, micro, super-microfibres

The polyester fibre shall be identified as per confirmatory and microscopic tests specified in IS 667 and based on parameters defined in this standard. The polyester staple fibre must meet the physical and chemical requirements specified in this standard. When tested using the method specified in Annex C of IS 16481, all virgin polyester staple fibres must have an isophthalic acid content zero. The polyester fibre must be free of major defects.

Polyester staple fibres (PSF) may also meet the environmental requirements outlined in this standard. The tests specified in the standard must be carried out according to the specifications in a properly equipped and staffed laboratory.


The test shall be carried out to determine the following according to the method specified.

  • Test for Shrinkage of single polyester staple fibre
  • Test for crimp properties of PSF and fibre fill/nonwoven fibres
  • Test for measurement of percent silicone on fibre
  • Moisture content test
  • Phosphorus content test
  • Antimony content in polyester
  • The hollowness of hollow fibre
  • Sinking time for spunlace fibre
  • Colour strength of the dope dyed product
  • Titanium dioxide in polymer

Packing and Marking shall be done in accordance with IS 17263: 2019. Each bale of PSF shall be marked with information as specified in this standard. Conforming to the requirements of this standard, the product(s) may be certified under the provisions of the Bureau of Indian Standards Act, 2016 and the Rules and Regulations framed thereunder, and the product(s) may be marked with the Standard Mark (ISI Mark). The Manufacturer must obtain a BIS license from the Bureau of Indian Standards to use a standard mark (ISI Mark). The BIS grants a license based on a successful assessment of manufacturing infrastructure, quality control and testing capabilities, and production process.
