BIS CERTIFICATION FOR POLYESTER PARTIALLY ORIENTED YARN
IS 17262: 2022

IS 17262:2022 covers polyester partially oriented yarn. This standard covers the requirements for all types of polyester partially oriented yarns (POY) for various end uses. 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. Polyester Partially Oriented Yarn (POY) is a continuous filament form of a synthetic polymer with a significant degree of molecular orientation, but further substantial molecular orientation is possible.

Classification of partially oriented yarn

The manufacturer must declare the filament yarn classification as described below when examined under a magnifying microscope:

1. Based on Cross Section, for Example Circular, Triangular, Trilobal, Angular Lobal Serrated, Profiled Oval Ribbon Like
2. Based on Cross-Sectional Area, for Example Solid, Hollow
3. Based on Multi-Component Fibres, for example, Concentric Cover-Core, Matrix, Sheath-Core
4. Based on Lustre (as Specified in this Standard)
• Full Dull (FD)
• Semi Dull (SD)
• Bright (BRT)
• Super Bright (SBR
• Optically White
5. Based on Dyeing Method (as Specified in this Standard)
• Cationic Dyeable (CD)
• Dope Dyed (DD)

This standard specifies a standard notation for yarn construction. The polyester POY must meet the construction and performance requirements specified in the standard. The polyester POY may also meet the environmental requirements outlined in the standard. The yarn must be free from major defects. The tests specified in the standard must be carried out according to the specifications in a properly equipped and staffed laboratory.

TESTS

The following test shall be carried out in accordance with the method specified.

• Determination of finish oil pick up
• Determination of interlace of filament yarn
• Determination of moisture content
• Phosphorus content
• Antimony content in polyester
• Titanium dioxide in polymer

The POY must be wound on bobbins containing 8 to 24 kg of yarn per bobbin. All bobbins must be packed in pallets or cartons that have been properly strapped with polypropylene/ PET strips, and Seaworthy packing material should be used. Each carton of POY must be marked with the information 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.
