SafeGuardS infant woven

GB/T 33734-2017< Woven Bedding for Infants > will be implemented on December 1, 2017. It is the first product standard for woven bedding for infants.

Since bedding articles are a type of product with prolonged direct skin contact, their quality largely affects the health and safety of humans, especially infants. However, at present, there is no specific standard for woven bedding for infants in China. In order to effectively ensure the health and safety of infants, the China National Standardization Technical Committees for Home-textiles has recently published the national standard GB/T 33734-2017 <Woven Bedding for Infants>. This standard will be implemented on December 1, 2017.This will standardize the production, sales and marketing of woven bedding for infants, protect the legal rights and interests of consumers and provide guidance for the woven bedding industry. The significant technical points of GB/T 33734-2017 are summarized as below.

1. Scope

This standard is applicable to bedding for infants (for ages not older than 36 months), which are mainly made of woven fabrics and include but are not limited to bed sheets, quilt covers, quilts, pillows, pillowcases, cushions, cushion covers, bumpers, mattress covers and  wrappers.

2. Quality level

This standard includes three quality levels: superior grade, first grade and qualified grade. This enables companies to choose the suitable quality level based on their product’s quality.

3. Product quality

Product quality includes safety performance, physical and chemical properties, appearance quality and technical quality.

4. Safety performance

The requirements of safety performance are given in Table 1.

Cords and drawstrings

Shall not exceed 230 mm for functional cords and drawstrings
shall not exceed 180mm for,decorative cords and drawstrings
shall not exceed 360mm for the circumference of loop
