Blending technique of eria silk and PTT (polyethylene terephthalate) dobby fabric

Abstract

The invention relates to a blending technique of eria silk and PTT (polyethylene terephthalate) dobby fabric. The blending technique comprises the steps of 1) placing eria silk in a steaming box, andsteaming for 80 min under the water temperature of 85-100 DEG C; 2) presetting the eria silk of the step 1) in natural state for 10-20 hours; 3) measuring tensile maximum of common silk, namely, maximum pressure applicable thereto; 4) blending the common silk and the eria silk with a water-jet loom under the maximum pressure. The tensile maximum of common silk, namely maximum pressure applicable thereto, is measured first; the tensile capacity of the common silk is weaker than that of the eria silk, and therefore, blending under the maximum pressure applicable to the common silk can ensure that tension of both the common silk and the eria silk are within a bearable range, and both the common silk and the eria silk rarely break.

Description

technical field [0001] The invention relates to a blending process of castor silk and PTT dobby fabric. Background technique [0002] When using different raw material yarns for mixed spinning, the tension of various raw material yarns and suitable processing temperature are important parameters that affect the quality of the final product. Therefore, it is necessary to take into account the characteristics of different raw material yarns when designing the textile process. When silk and castor silk are mixed and woven into fabrics, since the characteristics of silk and castor silk are quite different, a specific process is required for weaving. Specifically, silk has poor water resistance and is easy to break when exposed to water, and has weak tensile strength and is easy to break under force; while castor silk has high twist and strong tensile strength. In order to take care of the characteristics of different raw material silks to ensure the quality of the final product...

However, the effect of the above-mentioned traction and pretreatment process is still unsatisfactory, and there will still be more baffles in the final woven product.
