The Standardization Administration of China has
released a new national standard – GB/T 40270-2021 ‘Textiles-General technical requirements based on
consumer experience’.
Product standards have traditionally been
constructed from the perspective of product processes and technical levels; they
give no consideration to the consumer experience.
GB/T 40270-2021 introduces an assessment index
system based on the subjective
perceptions of the consumers, i.e., visual, tactile and olfactory. It applies
to end-use textile products, such as clothing and household textiles. The aim
is to make enterprises pay closer attention to consumer demands. This will lead
to the products that give better customer satisfaction.
Among the technical points in the standard
are:
- General safety – textile products must
conform to the requirements of GB 18401 or GB
31701 (products for infants and children) - Quality requirements – textile products must
conform claimed related product standard - Visual perception (characteristics) – textile
products include fiber shedding degree, pilling, resistance to pile loop
extraction, force to rupture pocket seams, seam slippage of pocket seams,
bursting strength of hosiery toe, colorfastness to washing (staining),
colorfastness to light yellowing, shedding of glitter and appearance after
laundering or dry-cleaning. Each testing item has its corresponding applicable
products or specific parts of product - Tactile perception (characteristics) –
textile products include prickle, water-vapor transmission rate, tactile sense
for permanent label (including brand), tactile sense for zipper, tactile sense
for touch and close fasteners, length for floats, slip resistance for hosiery.
Each testing item has its corresponding applicable products or specific parts
of product - Olfactory perception (characteristics) – textile
products shall have no pungent smell

will come into effect on December 1, 2021.
