One

GB/T 18886 - 2019

Textiles - Colour fastness test - saliva color fastness

GB/T 18886 - 2002

In order to accurately simulate the actual conditions of textiles, the revision adjusted the composition of artificial saliva and increased the artificial saliva. PH The requirement of the value, at the same time, further improves the operability of the method and the comparability of the results, and plays a certain role in improving the quality of textile products, especially the quality of infant clothing.

Two

GB/T 21655.2 - 2019

Evaluation of moisture absorption and dryness of textiles second part: dynamic moisture transfer method

GB/T 21655.2 - 2009

Moisture absorption and quick drying functional textiles are widely used in sportswear, mountaineering clothes, casual wear, underwear and so on because of their moisture absorption and rapid moisture permeability. The dynamic moisture transfer method is a commonly used method in the series of standards for testing and evaluating moisture absorption and quick drying functional textiles. Combined with the current development of product market, the standard has revised some assessment indicators, increased the marking requirements, unified the method of functional labeling, and further improved the requirements of instrument and equipment. The implementation of the standard provides a scientific basis for market supervision departments to supervise spot checks, and helps to create a good market competition atmosphere and protect consumers' rights and interests.

Three

GB/T 22701 - 2019

Rules for inspection of professional garments

GB/T 22701 - 2008

This standard has increased the inspection basis, increased the sampling plan and the batch determination, "where the supply and demand sides have the contract (agreement) stipulation, carries on the formulation in the contract (agreement) the sampling plan implementation" the expression; has revised the inspection project outline the content and the instruction request, deleted the instruction in the instruction durability label, the fiber content, the wash instruction explanation stipulation; has revised the appearance to sew the quality, the physical and chemical performance, the special function stipulation.

Four

GB/T 22703 - 2019

cheongsam

GB/T 22703 - 2008

This standard has increased. 3-14 The safety performance requirements for children wearing clothing increased the requirements of color fastness, color fastness and color fastness of fabrics, and increased the appearance requirements after washing.

Five

GB/T 22853 - 2019

Knitted sportswear

GB/T 22853 - 2009

This amendment fully takes into account the user's requirements for convenience and comfort in wearing clothes, and makes targeted modifications and complements to the old standards to make them more in line with the market demand for knitted sportswear at present. For instance, the pilling performance, bursting strength, the washing rate and the color fastness index are strictly enforced, and the requirements for moisture absorption and quick drying performance and appearance requirements are also increased. The requirements for surface defects, dimensional deviation and sewing quality are adjusted. The release of the new standard will provide more precise and specific guidelines for manufacturers and testing departments to provide consumers with safer and more comfortable knitted sportswear products, while helping to guide product innovation and production.

Six

GB/T 23317 - 2019

Technical requirements for moisture resistance of coated garments

GB/T 23317 - 2009

The standard has changed the scope of the standard and added to the age limit. Thirty-six Infants and young children under the age of 2 months and below have made sure that they only include woven coated garments, modified the requirements of static water pressure after twisting and bending, and increased the requirements of static pressure before washing and after washing.

Seven

GB/T 17760 - 2019

Testing method for defects of printed cloth surface

GB/T 17760 - 2009

The standard deleted the ten system grading method and the point counting method, supplemented the inspection equipment and the damaged defect scoring requirements.

Eight

GB/T 37629 - 2019

Textiles quantitative chemical analysis of mixtures of polyacrylonitrile fibers with certain other fibers (formic acid / zinc chloride)

Newly added

The two criterion is a simple and maneuverable Standard Test Method Based on the dissolution characteristics of new fibers in different solvents and the characteristics of different solvents, as well as the accumulation of practical detection cycle and practical experience, especially in improving the efficiency of experiments and reducing the use of toxic and harmful chemical reagents. These two standards provide a unified qualitative and quantitative method for the industry, which plays an important role in supervising the virtual label, the wrong content behavior, standardizing the market order, and protecting the rights and interests of downstream customers and consumers.

Nine

GB/T 37630 - 2019

Quantitative chemical analysis of textiles mixtures of acetate or three acetate fibers with certain other fibers (hydrochloric acid)

Newly added

Ten

GB/T 37631 - 2019

Test method for thermal decomposition temperature of chemical fibers

Newly added

The standard specifies the method of measuring the thermal decomposition temperature of chemical fibers by thermogravimetry.

Eleven

GB/T 37632 - 2019

Test method for chemical fiber TiO2 content

Newly added

The standard specifies a method for the determination of titanium dioxide content in chemical fibers by spectrophotometry. The standard is applicable to chemical fibers and functional chemical fibers can be used in reference.

Twelve

GB/T 37633 - 2019

Determination of textiles 1,2- two chloroethane, chloroethanol and chloroacetic acid

Newly added

The method established in this standard is applicable to textiles. One , 2- Two the quantitative and qualitative detection of chloroethane and its degradation products, namely chloroethanol and mono chloroacetic acid, has filled the blank of domestic testing technology in this project, and provided necessary technical support for improving the quality of textile products, protecting people's health, avoiding trade barriers and strengthening the quality monitoring of textile ecological safety.

Thirteen

GB/T 37635 - 2019

Test method for appearance change of elastic fabric ribbon fatigue resistance

Newly added

Elastic tapes are widely used in textile, clothing and home textiles. After repeated wearing or using, some elastic ribbons will weaken or disappear, and even the internal elastic fibers will break, which will seriously affect the appearance and performance of clothing. The formulation of the standard has made up for the lack of standards in the field, and can effectively characterize the fatigue resistance of the ribbon, and meet the needs of the elastic ribbon manufacturers and enterprises in various fields.
