In the presented study the effect of laundering on the quality of sewn cotton and bamboo plain woven fabrics was investigated considering both the textile parameters and the type of chemical treatment. Quality parameters of sewn cotton and bamboo woven fabrics such as: fabric strength, seam strength and seam slippage at the moment of 4 mm seam opening were evaluated before and after washing with “Tide” washing powder without softeners or with softeners: “Surcare” and “Pflege Weicspuler”. There was also determined surface density, warp and weft densities as well as thicknesses under the pressures 0.625 kPa and 3.125 kPa, and calculated the comparative thickness that was considered as softness or porosity of fabrics.

This paper explores the changes in the mechanical parameters of cotton fiber materials (woven and knitted materials) resulting from the chemical softening using two cationic liquid softeners. It was determined that these changes can be reflected and reliably evaluated using a method based on pulling a disc-shaped specimen through a central nozzle. The research also analyses the changes in textile mechanical parameters determined in pulling process, in material thickness as well as in surface friction coefficient resulting from wet textile treatment. It was determined that the washing of textile material influences the increase in their hand parameters and in thickness. The softening of washed textiles allows regenerating their hand properties similar to those of untreated ones.

In the present study the effect of technological treatment involving the processes of washing or washing and softening with chemical cationic softener "Surcase" produced in Great Britain on the surface properties of cellulosic textile materials manufactured from cotton, bamboo and viscose spun yarns was investigated. The changes in textile materials surface properties were evaluated using KTU-Griff-Tester device and FEI Quanta 200 FEG scanning electron microscope (SEM). It was observed that the worst hand properties and the higher surface roughness are observed of cotton materials if compared with those of bamboo and viscose materials. Also, it was shown that depending on the material structure the handle parameters of knitted materials are the better than the ones of woven fabrics.

The present research has explored the influence made by chemical softening with liquid household chemical softeners on changes in the structure and hand properties of the cellulose-origin textiles manufactured from cotton, bamboo and viscose spun yarns. Effectiveness of technological treatment has been analysed via application of an experimental method based on the pulling of a disc-shaped specimen through the central nozzle of KTU-GriffTester device. Analysis of the obtained results has demonstrated that washing of textiles leads to decrease in the hand parameters thereof such as the maximum pulling force (P max ), tangent of the slope angle of the typical pulling curve H-P initial part (tgα), pulling work (A) and complex hand parameter (Q) as well as in mechanical thickness ratio (Δδ) compared to the ones of the unwashed (control) textiles independent of the fibre content and manufacturing type thereof. Hand properties of the textiles under investigation have been shown to improve after chemical softening compared to the washed textiles, but they have never been comparable to the ones of the untreated (control) textiles. Chemical softening with the cationic softeners "Wansou" (V), "Pflege Weichspuler" (P) and "Surcare" (Sr) containing 5-15% of PAM has determined the best hand of the textiles under discussion compared to other chemical softeners.
