Abstract: The strength and elongation, the unevenness and the number of hairiness of the Newdal fiber/fine polyester blended yarn are tested. By the analysis of these results, the optimum blended ratio of the blended yarn is determined.

Abstract: The air-conditioning viscose fiber was blended with bamboo viscose fiber and polyester fiber in different blended ratios, and the evenness, hairiness, strength and elongation, and elasticity of blended yarns were tested. The influence of blended ratios was analyzed. The results show that: With the increase in air-conditioning fiber content, the CV value of evenness indicates an increasing trend and the yarn evenness goes bad, breaking strength, elongation at break, fracture work of blended yarns decreases linearly, and elastic recovery rate of blended yarns increases first, then decreases basically and the maximum appears at 40%. The difference of hairiness curves is small in different blended ratios. Elastic recovery rate of blended yarns decreases with the increase of specified elongation.

Abstract: The strength and elongation, the unevenness and the number of hairiness of the soybean protein fiber/fine-polyester blended yarn are tested. By the analysis of these results, the optimum blended ratio of the blended yarn is determined.

Abstract: In order to describe the relation between the elasticity and the blended ratio of PLA fiber blended yarn, the elasticity of different kinds of blended ratio of PLA/Modal and PLA/cotton blended yarn was measured. The relation between the elasticity and the blended ratio of blended yarn is determined. The optimum blended ratio is analyzed.

Abstract: The PLA fiber is one of the green fibers. It is blended with Tencel fibers. The strength of the PLA fiber/Tencel blended yarn is tested. The relationship between the strength and the twist factor and the blended ratio is analyzed. The optimum blended ratio and the critical twist factor of the blended yarn is determined.

Abstract: In order to describe the relationship between the elasticity and the strength and the blended ratio of soybean protein fiber/combed cotton blended yarn, the strength and elasticity of different kinds of blended ratio of soybean protein fiber/combed cotton blended yarn was measured. The relationship between the strength and the blended ratio of blended yarn is not in accordance with the simple model. With the increase of the blended ratio of the soybean protein fibers, the strength and the elasticity of the blended yarn increased.

Abstract: The soybean protein fiber is one of the green fibers. It is blended with the fine polyester. The strength of the blended yarn is tested. The relation between the strength and the twist factor and the blended ratio is analyzed. The optimum blended ratio and the critical twist factor is determined.

Abstract: The strength and elongation, the distribution of the soybean protein fibers and the bending rigidity of the soybean protein fiber/polyester blended yarn are tested. By the analysis of the results, the optimum blended ratio of the blended yarn is determined by the multi-objective optimization method.

Abstract: In order to study the effect of different blended ratios on strength and elongation properties of Outlast/viscose blended yarn, ten kinds of blended yarns had been designed and spun. The blended ratios were Outlast/viscose 0/100, 15/85, 25/75, 30/70, 35/65, 40/60, 45/55, 50/50, 60/40, 100/0. By testing the strength and elongation properties of the blended yarn, the effect of blended ratio on blended yarn’s breaking tenacity and elongation rate was analysed. The results showed that, with the increase of blended ratio, the breaking tenacity and breaking elongation rate of the blended yarn both presented a downward trend. But when Outlast/viscose blended ratio was 35:65, breaking elongation rate had a maximum value. When blended ratio was 45:55, breaking tenacity had a maximum value, which should be used in practice.

Abstract: For fabrics, the diversification and superior of the properties and the styles can be achieved by blending fibers. To keep up with the demand of the market, PTT, PLA and Rayon were selected as the materials and 10 kinds of PTT/PLA/Rayon blended fabrics with different fiber content were designed and woven. And then the wearabilities of the fabrics were tested respectively. At last, fuzzy evaluation wad used to discuss the affection of the blended ratio on the fabric’s wearability. The results show that various kinds of wearabilities of the fabric are the best when the blending ratio is PTT/ PLA/Rayon 40/30/30.
