ABSTRACT
As the functional textiles market expands rapidly, people's requirements and focus on functional textiles have shifted to multi-functional, cost-effective, and high standards. Meanwhile, the continuously rampant COVID-19 epidemic has greatly increased the demands for antibacterial and antiviral functional textiles. As the most widely produced and sold artificial fibre, traditional PET fabric has some disadvantages easy to gather static electricity, poor moisture-penetrability, and poor colourability. This study aims to develop a low temperature cationic dyeable environmentally-friendly PET fabric with bacteriostatic and fast-drying functions, and to increase the product added value, thereby meeting the ever-growing consumption needs. A multi-functional polyester fibre with antibacterial, hydroscopic and fast-drying functions is developed using modified low-temperature cationic dyeable cross-sectional polyester filament yarn and antibacterialpolyester filament yarn. A series of low-temperature cationic dyeable fabrics with hydroscopic, quick-drying and antibacterial properties were prepared by cross orthogonal method. The cross-sectional polyester fibre as a profiled sectional product has multiple grooves longitudinally, greatly increasing its specific surface. The fibres and filament yarns have excellent breathability, moisture permeability, and dyeability. Adding antibacterial masterbatch to PET antibacterial polyester during spinning can achieve reliable antibacterial performance of the fibre layer, which has advantages of good laundering durability, easy production and excellent antibacterial property. In this study, cross-section polyester filament yarn is used as the warp yarn of the fabric. The weft yarn adopts alternative weft knitting between cross-sectional polyester filament yarn andantibacterial polyester filament yarn, with the weft knitting ratio of 10, 14, 13, 12, 11, 21, 31 and 41, respectively. The warp density is 650 ends/10 cm, and the weft density is 450 picks/10 cm. The satin weave structure is selected in the experiment for better hand feeling and appearance of the fabric, and to meet the requirements of product hydroscopic and antibacterial application. Its hydroscopic and fast-drying properties are evaluated by measuring its wicking height, dripping diffusion rate, water absorption and evaporation rate, moisture permeability etc. The oscillation method is used to determine the fabric antibacterial properties against Escherichia Coli and Staphylococcus Aureus. TOPSIS integrated algorithm is used to analyze the optimal process. The results show that the interwoven fabric has excellent bacteriostatic performance, and the antibacterial rate of all samples exceeds 70%. At the same time, the fabric has excellent moisture absorption and fast drying performance;the dripping diffusion time is less than 5 seconds, the average water absorption rate exceeds 150% and the average evaporation rate is more than 90% in 20 minutes. Besides, it is found that the higher weft yarn ration of the cross-sectional hydroscopic and fast-drying polyester, the better hydroscopic fast-drying performance of the fabric. The interwoven fabric obtained through TOPSIS algorithm method with cross-sectional polyester/antibacterial polyester proportion of 14 has the optimal comprehensive performance. Experimental results show that this process can effectively solve polyester fabric disadvantages of poor moisture-penetrability, tendeny to gather static electricity, and poor colourability and add excellent bacteriostatic performance. The alternative weft knitting between hydroscopic fast-drying polyester and antibacterial polyester, and TOPSIS comprehensive analysis method can help effectively develop multi-functional fabrics. Besides, adding other functional fibre or yarns on this basis is conductive to achieving other functions like ultraviolet protection, deodorization, skin care, etc. The research results of this study can provide a reference for the design of functional textiles. © 2022 China Silk Association.
