New Edition Of "Technical Requirements For Physical And Chemical Properties Of Garments" Issued By The National Standard

Recently, reporters from the national textile and clothing quality supervision and inspection (Jinjiang, Fujian) clothing sub center (hereinafter referred to as "national textile and garment quality inspection Jinjiang sub center") learned that the State Administration of quality supervision, inspection and quarantine, the National Standardization Management Committee issued the Announcement No. twenty-first in 2014, and approved the 259 national standards of "chemical reagent six methyl four amine", including 10 textile related standards.

according to understand The 10 textile related standards include GB/T 21295-2014 "technical requirements for physical and chemical properties of clothing", GB/T 21294-2014 "testing methods for physical and chemical properties of garments", GB/T 5455-2014 "determination of vertical damage length of textile combustion properties, measurement of smoldering and continuous combustion time", and GB/T 31128-2014 "towel towel loop test method" and other important standards. Most of the standards were implemented in March 1, 2015.

In the 10 textile related standards, Wang Zhiyong, director of the Jinjiang Sub Center Laboratory of the national textile and garment quality inspection center, introduced the technical requirements of GB/T 21295-2014 "physical and chemical properties of clothing". Wang Zhiyong told reporters that the standard replaces the technical requirements of GB/T 21295-2007 "physical and chemical properties of clothing". It supplements and modifies terms and definitions, adds safety performance requirements, functional evaluation and technical requirements for detection methods, and adds "list of specific substances for fire retardant", "list of specific substances of o-phthalate two formic acid", "list of specific substances of alkylphenol (AP) and alkylphenol polyoxyethylene ether (APEO)", and eliminates specific indexes of heat preservation rate and air permeability.

"The standard It increased the requirements of color fastness to hot pressing (tidal pressure discoloration, stain), dye blending, dye migration and phenolphthalein. It increased the requirements of flame retardant finishing agent, phthalic acid two ester, total lead content, alkylphenol (AP) and alkylphenol polyoxyethylene ether (APEO), which increased the hydrostatic pressure resistance, UV protection, anti hook performance, moisture absorption and quick drying performance, oil repellency and easy decontamination performance. Zhi Yong Wang Told reporters that the standard stipulates that the hydrostatic pressure of finished products with waterproof and hydrostatic performance requirements is not less than 13kPa, and the static water pressure of finished products with rainproof function requirements is not less than 35kPa. The resistance of finished products with anti hook wire requirements is not less than 3-4.

In addition, according to Wang Zhiyong, the new standard has revised "slippage" to "seam performance". The results of stitch breakage test showed that fabric breakage, slippage and suture fracture were judged to be unqualified. Light and thin silk products, hollowed out and rotten fabrics are not evaluated, but the cautionary terms for related notices should be indicated in the product instructions. At the same time, the new standard stipulates that the allowable degree of pilling is not less than 3.
