Sales of thermal underwear Product number type according to GB/T1335.1--1335.3 (GB/T3:11. 4 Requirements
Knitted thermal underwear product requirements are divided into two aspects: internal quality and external quality. Internal quality includes strong needle fiber F
FZ/T 730222004
Contains nine items: temperature, air permeability, pilling, water-sinking size change rate, and color fastness. Appearance inspection includes four categories: surface inspection, size difference, body size difference, and durability. 4.1 Grading regulations
4, 1.1 The quality of knitted underwear products is divided into superior products, second-class products, and qualified products. 4.1.2 The internal quality of knitted underwear products is evaluated according to the evaluation level, appearance, and quality. The average quality is determined as the lowest quality. 4.1.3 The internal quality is evaluated according to the lowest quality item in the test. 4.1.4 The appearance is evaluated according to the four items. The lowest item of the result is used as the basis for the evaluation of the batch of products. Only two people are allowed to make the same item in the batch. This will reduce one level. 4.2 Intrinsic quality requirements
