The adaptive neuro-fuzzy system inference （ANFIS） and Multiple Linear Regression models are used to predict the rotor spun yarn strength. Fiber properties and yam count are used as inputs to train the two models and the count-strength-product （CSP） was the targel. The predictive performances of the two models are estimated and compared. We found that the ANFIS has a better predictive power in comparison with linear multiple regression model. The impact of each fiber property is also illustrated.展开更多

Experimental work showed that denim cloth produced from the modified rotor yarn has superior properties over conventional rotor yarn in terms of surface texture and appearance,tearing strength and resistance to abrasion.展开更多

The results show that with the same raw material and twist, the rotor spun yarn has lower abrasion resistance than that of ring spun yarn, because of the higher twist employed, the abrasion resistance of rotor spun yarn is higher than that of ring spun yarn.展开更多

Because of no yarn properties standard available at present for suchlike yarns, it is considered necessary to analyse the acceptability of coarse pure ramie noil rotor-spun yarns in terms of yarn properties before their products being developed. By the aid of a hypothetical concept "pure ramie noil ring-spun yarn", this paper draws the conclusion that the coarse pure ramie noil rotor-spun yarns are condsidered acceptable to a great extent; furthermore, it introduces 5 kinds of woven fabrics and 3 kinds of knitted fabrics successfully designed and developed from those yarns.展开更多
