The Features And Reeling Technology Of Duppion Silk Yarns

Under the influence of going back to nature, duppion silk yarns and its product was increasingly popular on the international market in recent years. However, reeling technology of duppion silk yarns relatively fell behind, the features of duppion silk was not obvious, the degree of robotization was relatively lower, the quality of product was cheesy. So, the mechanism of producing feature of duppion silk yarns required analysis, the reeling technology of duppion silk yarns need to research.Aim at existent problem of reeling duppion silk yarns. First, research into quality characteristic of raw cocoon(include twin cocoon and common cocoon), By experiment and analysis, we were aware that the volume of twin cocoon is relatively big and skimble-scamble, the layer of twin cocoon is thick and loose, easily contributed to uneven of absorbing water among twin cocoon when permeated to it.Whereas enhanced the pressure of vacuum pump or usage of chemical can reduced the discrepancy, and improved the temperature of water can decrease the broken of silk when reeling silk. Then, through trial of reeling silk from a cocoon and observation of the process, established model of reeling silk from twin cocoon.By experiment and analysis, we know that snarly two cocoon silk was simultaneity draw up and disorderly separate silk from cocoon bring on the feature of duppion silk yarns. Again, for the sake of the methods of controling amount of feature of duppion silk yarns, put forward a new method that adding fresh twin cocoon to raw cocoon of reeling duppion silk yarns, and make use of orthogonal experimental to study the impact about adding fresh twin cocoon of ratio, times of process of boiling cocoon, the usage of chemical additives and other factors to improve the amount features of duppion silk yarns. Achieved notable result that the times of process of boiling cocoon and the use of chemical additives can improve amount of features of duppion silk yarns, And confirmation that this methods can improve the amount of features of duppion silk yarns. End, as viewed from filature machine, researched into relation between the produced feature of duppion silk yarns and automatical filature machine, we confirmed that new automatical filature of duppion silk yarns had made a great impact on the quality and output of reeling duppion silk yarns .
