The present study is aimed at analyzing the effect of dry-cleaning solvent on the physical properties of cotton, silk and wool fabrics. The sourced fabrics are dry-cleaned with two different commercial solvents, namely mineral turpentine oil, and dipropylene glycol dimethyl ether. The fabrics are dry-cleaned separately for 5, 10 and 15 times with each solvent and analysed for their performance. The results indicate that the dry-cleaned fabrics become thicker and bulkier, and hence their air permeability, bending ability, crease recovery, tearing strength and abrasion resistance reduce. The water absorbency, stiffness and thickness of the fabrics are found to be increased significantly. The statistical analysis results confirm that the changes in the fabric are significant with 95% confidence limit (p 0.05). Out of the selected dry-cleaning solvents, hydrocarbons are found to be more aggressive than the glycol ethers in terms of fabric deterioration, except tearing strength. The GC-MS analysis results confirm the presence of dry-cleaning solvents deposits on the fabric even after 24 h of airing out process.

反复干洗过程对棉，丝绸和羊毛织物物理性能的影响

本研究旨在分析干洗溶剂对棉，丝和羊毛织物物理性能的影响。来源的织物用两种不同的商业溶剂干洗，即矿物松节油和二丙二醇二甲醚。用每种溶剂分别将织物分别干洗5、10和15次，并分析其性能。结果表明，干洗织物变厚和膨松，因此其透气性，弯曲能力，折皱回复性，撕裂强度和耐磨性降低。发现织物的吸水性，刚度和厚度显着增加。统计分析结果证实，织物的变化显着，置信度限制为95％（p 0.05）。在选定的干洗溶剂中，发现烃在撕裂强度方面比乙二醇醚更具侵蚀性，不仅破坏织物，而且破坏织物。GC-MS分析结果证实即使在晾干24小时后，干洗溶剂仍会沉积在织物上。
