Textiles - Professional care drycleaning and wetcleaning of fabrics and garments - Part 3: Procedure for testing performance when cleaning and finishing using hydrocarbon solvent
1 Scope
This Part of GB/T 19981 specifies drycleaning procedures for hydrocarbon solvents, using commercial drycleaning machines, for fabrics and garments. It comprises procedures for normal and sensitive materials (see Article 3.3 and Article 3.4).
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
Example: Acrylics, silk, crepe, chlorofibre, modacrylic, novelty tweeds, angora.
Note: Giving careful consideration to the comments on progressive change made in the Introduction, textile items that perform satisfactorily for purpose in the procedures intended for normal and sensitive materials, listed in Table 1, may be labeled with the ○F and ○F symbols respectively, as described in GB/T 8685.
4 Principle
The specimen, or specimens, are drycleaned in a commercial drycleaning machine and finished according to one of the specified procedures. This process is a precursor to the assessment of the cleaned specimen in accordance with GB/T 19981.1.
5 Reagents
5.1 Hydrocarbon solvents
Hydrocarbon solvents used for drycleaning are aliphatics (CnH2n-2; n=10~12) or iso- and cyclo-aliphatics, flashpoint W 38 °C, boiling range 150 °C to 210 °C.
5.2 Detergent
Cocofattyaciddiethanolamlde
Note: In order to prevent foaming, it is important to use redistilled, clean solvent solution and not overfill the still.
