Comprehensive wear-ability evaluation of hollow coffee carbon polyester/cotton blended knitted fabrics. Issue 1 (January 2023) - Zhang, Chentian
As a new kind of functional fiber, hollow coffee carbon polyester (HCCP) has the advantages of antibacterial and warmth retention properties. HCCP's wear-ability performances in knitted textiles were studied by changing the specifications of the raw materials, blending ratios and knitted structures. Plain knit, interlock knit and Ponte knit fabrics were prepared with compact siro-spun HCCP/cotton yarns in five different blended ratios. Eight groups of experiments were conducted to test the performances of the mechanical properties, comfortable capability and antibacterial behavior. Then a comprehensive wear-ability evaluation was made based on the grey clustering analysis method. Results revealed that fabrics with a higher blended ratio of HCCP showed more preferred performance in terms of bursting strength, air permeability, moisture absorption, warmth preservation and antibacterial property, but the anti-pilling performance showed a downward trend. Compared to plain stitch, the interlock knit and Ponte knit fabrics showed a visibly better result.
