Abstract

The invention relates to a method for modifying continuous multistage cotton and linen yarns, which is characterized in that cotton and linen yarns are hanked and subjected to liquid ammonia modifying and drafting at the same time, and are then subjected to microwave drying and drafting simultaneously. The drafting is carried out during the liquid ammonia modifying and the microwave drying, so the cotton and linen yarns are modified through various modes of liquid ammonia, drafting, microwave and the like, and the softness, wrinkle resistance, crack resistance, smooth type, bulkiness, dyeing property and the like of the cotton and linen yarns can be improved.

Description

[0001] This application is a divisional application with an application date of May 17, 2011, an application number of 201110127490.8, and a title of "A Continuous Multi-station Cotton and Linen Yarn Modification Device and Method" technical field [0002] The invention relates to a continuous multi-station cotton and linen yarn modification method, which belongs to the technical field of textiles. Background technique [0003] Natural fiber fabrics such as cotton and linen yarn are more and more valued by people because of their superior properties, such as sweat absorption, good air permeability, and harmlessness to the human body. But they also have the disadvantages of easy wrinkling, shrinkage, rough hand feeling and poor dyeing property. Cotton and linen yarn modified by liquid ammonia is not easy to shrink, soft to the touch, and has certain wrinkle resistance; the mechanical properties and viscoelasticity of cotton and linen yarn after drafting in the ammonia soaking...
