Shrink-Proof Treatment Parameter Optimisation of Cashmere Yarn

Li Long, Wang Wei, Zhang Xian, Wu Lei, Yang Dan

Fibres & Textiles in Eastern Europe

2022

Vol. 30, no. 3

57--60

Cashmere fiber has soft hand and good elasticity. However, it exhibits shrink because of its scale. In this work, cashmere yarn (38.26 tex) was treated using NaCl-KMnO4 to reduce the shrink of cashmere yarn. Orthogonal design and fuzzy comprehensive evaluation were used for optimizing treating parameters. Experimental results showed that the yarn shrink percentage of treated yarn was 0.56% which was less than that untreated yarn, and the treated yarn strength had a little drop compared with untreated yarn. The fiber scale outline of treated yarn could be observed by SEM, but the scale edge is blunt and irregular.

Research on rural environmental pollution control path under administrative intervention mechanism

Wu Lei, Wang Chengsi

Ecological Chemistry and Engineering. S

With the continuous development of urbanisation, the economic level of rural areas has improved greatly. However, due to the development of industry and the leap in the economy, the rural environment has suffered unprecedented damage. Taking Zhejiang Province as an example, this paper explores the rural environmental pollution control path under the government intervention mechanism. Firstly, it analyses the functions of the government in rural environmental pollution control. Then, taking Huzhou as an example, this paper empirically evaluates the willingness to pay for the treatment of living environment pollution in rural areas of Huzhou based on the CVM (Contingent Valuation Method) and analyses the decentralised domestic sewage treatment mode, multi household domestic sewage treatment mode, and waste collaborative treatment mode from the perspective of treatment technology and policy system. Finally, it is proposed that to speed up the governance of the rural environment, and we must strengthen the administrative intervention of the government in rural environmental governance. The government should improve the environmental protection awareness of leaders at all levels and the masses and enrich farmers’ environmental governance knowledge and technical training. Based on the theory of environmental economics, agricultural economics, and decision-making behaviour, this paper analyses the influence mechanism of farmers’ decision-making behaviour and government intervention in rural non-point source pollution control.
