Scope

Scope: This document specifies the classification, marking, requirements, test methods, inspection rules, and labeling and packaging of polyester particle cotton yarn in its natural color (hereinafter referred to as "polyester particle yarn"). This document is applicable to the quality assessment of polyester particle yarn produced by ring spinning machines, but not to the quality assessment of polyester particle yarn for special purposes. Main technical content: 1. Scope: This standard specifies the classification, marking, requirements, test methods, inspection rules, and labeling and packaging of polyester particle cotton yarn in its natural color (hereinafter referred to as "polyester particle yarn"). This standard is applicable to the quality assessment of polyester particle yarn produced by ring spinning machines, but not to the quality assessment of polyester particle yarn for special purposes. 2. Terms and definitions: Polyester particles are fiber particles with a diameter of 1–2 mm made from polyester fibers through a special process; polyester particle cotton yarn is yarn whose base yarn is 100% cotton, with polyester particles evenly distributed along the length of the yarn, which may be colored or natural in color. 3. Innovative indicators in the standard: The particle shedding rate is the percentage of polyester particles shed from the yarn relative to the original yarn mass. Test method for particle shedding rate: On a yarn-counting parallelizer or winder, wind the polyester particle yarn onto a cylinder with a known weight of 100 m in length. Weigh the cylinder (including yarn) to obtain the yarn mass, denoted as m0; then wind the yarn onto another cylinder with a known weight, weigh the cylinder (including yarn) to obtain the yarn mass, denoted as m1. Repeat the above operation until the change rate of the mass obtained from two consecutive weighings does not exceed 2%, at which point the test can be concluded. The mass of the yarn obtain
