GB/T 19981.2-2005 in English

《GB/T 19981.2-2005纺织品 织物和服装的专业维护、干洗和湿洗 第2部分:使用过氯乙烯干洗和整烫时性能实验的程序》由TC209（全国纺织品标准化技术委员会）归口，TC209SC1（全国纺织品标准化技术委员会基础标准分会）执行，主管部门为中国纺织工业联合会。
本部分规定了使用商用干洗机和四抓乙烯(过氯乙烯)对织物和服装进行干洗的程序。包括正常材料的干洗程序、敏感材料和特敏材料的干洗程序。
注:
1 多种溶剂可用于干洗，但在许多国家中最常用的干洗溶剂是四抓乙烯。因此，本部分使用了四氛乙烯。
2 使用商用干洗设备时，应遵守国家的法规和常用安全规则。

1 Scope

This Part of GB/T 19981 specifies drycleaning procedures for tetrachloroethene (perchloroethylene), using commercial dry-cleaning machines, for fabrics and garments. It comprises a procedure for normal materials and procedures for sensitive and very sensitive materials.
Notes:
1 Various solvents can be used for drycleaning, of which tetrachloroethene is the most common in many countries. For this reason, the present method prescribes the use of tetrachloroethene.
2 When using commercial drycleaning equipment, national regulations and normal safety precautions should be observed.

3 Terms and Definitions

For the purposes of this Part of GB/T 19981, the following terms and definitions apply.
3.1
Materials
Fabrics, garments or composites
3.2
Composite test specimen
Test specimen consisting of all component parts used in the finished item, and combined in a representative assembly
3.3
Normal materials
Materials that are able to withstand the normal drycleaning process as specified in this Part of GB/T 19981 without modification
3.4
Sensitive materials
Materials that may require restrictions as to mechanical action and/or drying temperatures and/or water additions
Examples: Acrylics, silk and crepe.
3.5
Very sensitive materials
Materials which may require greatly reduced mechanical action and/or greatly reduced drying temperatures and/or no addition of water
Examples: Polyvinylchloride (PVC), modacrylic, novelty tweeds and angora.
Note: After giving careful consideration to the comments on progressive change made in the Introduction, textile items which perform satisfactorily for purpose in the procedures intended for normal and sensitive materials in Table 1, may be labeled with the ○P and ○P symbols respectively, as described in GB 5296.4. There is no care label equivalent to the procedure for very sensitive materials and information on the required processing can only be given in words.

4 Reagents

4.1 Tetrachloroethylene (Cl2C=CCl2), distilled, sold for the purpose of drycleaning.
4.2 Sorbitan mono-oleate (Span 80)
Note: In order to prevent foaming, it is important to use redistilled, clean solvent solution and not overfill the still.
