The influence of cotton/polyester fabric structure to its alkaline pretreatment

The influence of fabric structure of cotton/polyester blend to its alkaline pretreatment has been researched. For this purpose, three fabrics of different weft density in twill weave were pre-treated in NaOH with addition of anionic surfactant. The characterization of fabrics was performed by electrokinetic analysis (SurPASS, Anton Paar). The fabric changes were determined by standard methods: breaking force and elongation (ISO 13934- 1:2013), fabric count (ASTM D3775-17e1), mass per unit area (ISO 3801:1977), degree of whiteness (ISO 105 J02:1997), water retention value (ASTM D2402-07(2018)), and the liquid moisture management properties (AATCC TM 195-2017). Due to different weft density, swelling capacity of fabrics is different and for that reason the pre- treatment results in different level of modification, absorption ability and liquid transport.
