Introduction
The current product standards are prepared mainly based on the current production process and overall technical level, and less consideration is given to consumer experience. From the perspective of consumer experience and based on the characteristics of tactile perception, visual perception and olfactory perception, this document constructs an assessment index system different from the current product standards, that is, on the basis of basic safety and quality requirements, this document assesses the characteristics of tactile perception, visual perception and olfactory perception, trying to make the assessment items intuitively reflect the needs of consumers.
This document, as a general technical requirement for end textile products for clothing and household, aims to guide enterprises to pay close attention to the development direction of standardized technology which is guided by consumer demand and gives consumers a good experience when products are designed and produced, and strive to avoid unpleasant experience given in products to consumers. Therefore, when used by all related parties, this document should not be regarded as an express standard for certain products, and shall not be recommended as the basis for product quality supervision, spot check and open comparison.
