Effect of blending ratio on the hollow coffee carbon polyester/cotton blended yarn

In order to solve the difficulty of starch being insoluble under medium and low temperature, a cationic starch slurry modified with etherification was developed. Raw starch was hydrolyzed by sodium hydroxide to improve the dispersion performance, and then the hydrolyzed starch was endowed with cationic groups by N-2,3-epoxy-propyl trimethyl ammonium chloride to improve the dispersion stability. Through various characterization methods, it was found that the quaternary ammonium cationic starch obtained was dissolved in water at medium and low temperature, and the starch structure was changed under the influence of sodium hydroxide and N-2,3-epoxy-propyl trimethyl ammonium chloride. Furthermore, the mechanical properties and abrasion resistance of cotton yarn treated with cationic starch could be significantly improved. Compared with the original yarn, the breaking strength of the yarn treated with cationic starch was increased by 70.05%, the hairiness index of the yarn was reduced by 87.5%, the abrasion resistance was increased by 500.00%, and the stiffness decreased by 276.47%. In addition, the Zeta potential of modified starch was positive, and the degree of etherification substitution of starch ranged from 0.02 to 0.26. The preparation method of etherified starch obtained has the advantages of environmental protection, low cost, and a simple process, which provides a novel way to construct textile size.

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.

Investigation into the effect of the blend ratio on the structure and properties of dual-feed-opening rotor-spun yarn

The scope of this study was to investigate the effect of the blend ratio on the structure and properties of dual-feed-opening rotor-spun yarn. A variety of yarns with different blended ratios were spun from two viscose fibers with the same properties but different colors. Through digital image processing technology, the ratios of the area occupied by the two fibers on the surface and the cross-section of the yarns were obtained. The results showed that the yarns with blend ratios of 40/60 and 50/50 had an obvious spacing phenomenon of two fiber segments on the surface. The ratio of the area occupied by the two fibers on the yarn surface was not equal to the value of the blend ratio. In the yarn cross-section, the difference in the area ratio of the two fibers to the blend ratio was subtle. The blend ratio had little effect on the mechanical properties (strength and elongation at break). However, the quantities of hairiness fluctuated greatly. The mass irregularity and imperfections decreased as the blend ratio approached 50/50. This work provides important guiding insights for the research of dual-feed-opening rotor-blended yarn.
