Scope

Scope: This document specifies the terms and definitions, general principles, quality requirements, test methods, inspection rules, marking, packaging, transportation, and storage for polyester digital sublimation transfer printing fabrics. This document applies to pre-printing fabrics made of pure polyester or polyester-ammonia blends used for digital sublimation transfer printing, as well as finished polyester digital sublimation transfer printing fabrics after the process. Main technical content: 1. Standard name: - According to GB/T 4146.1-2020 "Textiles - Chemical fibers - Part 1: Generic names", polyester fibers include three types: polyethylene terephthalate (PET, commonly known as "polyester"), polyethylene isophthalate (PEI), and polyethylene butylene terephthalate (PTT). Polyester is one type of polyester fibers, and polyester fiber fabrics dominate the market. - Since digital printing can be divided into digital direct printing and digital sublimation transfer printing, and this standard primarily focuses on digital sublimation transfer printing, the standard name was modified from the original "General Technical Requirements for Digital Printing on Polyester Fabrics" to "Quality Requirements for Digital Sublimation Transfer Printing Polyester Fabrics". After technical review, the final standard name was determined as "Quality Requirements for Digital Sublimation Transfer Printing Polyester Fabrics". 2. Scope: - The digital sublimation transfer printing process for polyester fabrics requires a certain polyester content in the substrate fabric. Polyester content is one factor affecting printing effect and quality. After research, it was determined that the digital sublimation transfer printing process is mainly applied to pure polyester fabrics and polyester-ammonia blended fabrics. Therefore, the scope of the standard is defined as: This document applies to pre-printing fabrics made of pure polyester or polyester-ammonia blends used fo
