BIS Certification for Polyester Spun Grey & White Yarn

Polyester spun grey & white yarn is a type of yarn that is exclusively made from 100% polyester fibers in shades of grey and white. It is manufactured using methods such as ring spinning, open-end spinning, or airjet/vortex spinning. This type of yarn is widely utilized in the textile industry for various purposes.

Polyester spun grey & white yarn is commonly employed in the production of fabrics used for clothing, home textiles, upholstery, bedding, and industrial textiles. It is highly regarded for its exceptional qualities such as durability, strength, and resistance to wrinkles, shrinking, and fading.

These yarns can be blended with other fibers or used independently to create a diverse range of fabrics with distinct textures and characteristics. Let’s go through the legalities of BIS Certification for Polyester Spun Grey & White Yarn and how you can secure it.

What is the Role of IS17265:2022?

The IS17265:2022 covers 100% polyester spun yarn in shades of grey and white. This Indian Standard was adopted by the BIS (an apex authority) following the authentication of the draft by the Man-Made Fibres, Cotton, and Their Products Sectional Committee.

Polyester spun yarns are manufactured using ring spinning, open-end spinning, or airjet/vortex spinning techniques with 100 percent polyester staple fibers. The BIS Certification for Polyester Spun Grey & White Yarn revolve around these guidelines.

The standard specifies the criteria for various types of 100% polyester spun yarns, including single, double, and multifold yarns, which are made exclusively from new polyester fibers.

Classification of Spun Yarn

Following is the classification of spun yarn:

Based on Cross Section

  • Trilobal
  • Triangular
  • Ribbon
  • Circular
  • Profiled Oval
  • Angular Lobal Serrated

Based On Cross-Sectional Area

  • Solid
  • Hollow

The yarns made from 100% polyester spun single and double (two-fold) must be exclusively crafted from pure virgin polyester fiber cut staples. It is imperative for these yarns to adhere to the prescribed constructional and performance criteria outlined in the standard. To ensure the purity of the fibers, it is necessary for the polyester fiber’s isophthalic acid content to be completely absent. This can be verified through the designated testing method detailed in Annex C of IS 16481.

Mandatory Tests for BIS Certification for Polyester Spun Grey & White Yarn

  • Hairiness index
  • Phosphorus content
  • Antimony content in polyester
  • Titanium dioxide (TiO2) in polymer
  • Moisture regain of polyester spun yarns

Packing and Marking Norms under BIS Certification for Polyester Spun Grey & White Yarn

The packaging and labeling of the polyester spun yarn should adhere to the guidelines specified in IS 17265:2022. Each carton containing the yarn must be marked with the required information according to the standard.
