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.
Table 1 Safety performance
| Item | Superior grade | First grade | Qualified grade | |
|---|---|---|---|---|
| Formaldehyde content /(mg/kg) |
Shall comply with the requirement of GB 31701 | |||
| pH value | ||||
| Odor | ||||
| Banned azo colourants | ||||
| Heavy metal /(mg/kg) ≤ | Pb | |||
| Cd | ||||
| Phthalates /(%)≤ | DEHP+DBP+BBP | |||
| DINP+DIDP+DNOP | ||||
| Burning behaviour | ||||
| Sharp objects | ||||
| Removal force of attached components/N | ||||
| Accessible sharp points and sharp edges of attached components | ||||
| Filling materials | ||||
| Colorfastness to dry rubbing/grade | ||||
| Colorfastness to saliva/grade | ||||
| Colorfastness to perspirationa/grade ≥ | Change/Staining | 4 | 3-4 | 3-4 |
| Colorfastness to watera/grade≥ | Change/Staining | 4 | 3-4 | 3-4 |
| Colorfastness to wet rubbingb/grade | 3-4 | 3 | 3 | |
| Cords and drawstrings | Shall not exceed 230 mm for functional cords and drawstrings | |||
| Note: For woven bedding for infants, it is not recommended to use flame-retardant finishing. If flame retardant finishing of cotton fabric is carried out, it must comply with related Chinese regulations and mandatory standards. | ||||
a Does not apply to undyed and bleached products. b Does not apply to original and bleached products; the technical requirement of first grade and qualified grade can be reduced by a half grade for dark colours. According to GB/T 4841.3, color which is greater than 1/12 dyestuffs dyeing standard depth colour card can be defined as a dark colour. | ||||
5. Physical and chemical properties
Physical and chemical properties are given in Table 2. Silk quilts, down & feather quilts, down & feather mattresses, down & feather sleeping bags, down & feather pillows and cushions shall comply with the requirement of their individual product standards.
Table 2 Physical and chemical properties
| Item | Superior grade | First grade | Qualified grade |
|---|---|---|---|
| Mass deviation of filling materials/% ≥ | -5.0 | ||
| Oil content of,filling materials a /% ≤ | 1.0 | ||
| Fiber content/% | Shall comply with the requirement of GB/T 29862 | ||
| Breaking force/N ≥ | 250 | 250 | 220 |
| Pilling property/grade ≥ | 4 | 3-4 | 3 |
| Dimensional stability to washing b /% | -3.0～+3.0 | -4.0～+4.0 | -5.0～+5.0 |
| Colorfastness to light c /grade ≥ | Dark color 4 Light color 3 | Dark color 4 Light color 3 | Dark color 3 Light color 3 |
| Colorfastness to washing with,soap or soap and soda d /grade ≥ | Change 4 Staining 4 | Change 3-4 Staining 3-4 | Change 3 Staining 3 |
| Note: For the quilt core test only mass deviation of filling materials, oil content of filling materials and fiber contents. For the pillow core and cushion core test only fiber content. | |||
a Do not test,oil content for natural cellulose fiber filling materials. b Do not test dimensional stability to washing for quilting goods. c According to GB/T 4841.3, colour which is greater than 1/12 dyestuffs dyeing on the standard depth colour card can be defined as dark colour. d Do not apply to undyed and bleached products. | |||
