Abstract

A bamboo fiber hemp core-spun yarn disclosed by the invention comprises an outer covering yarn and a core yarn, the outer covering yarn is made of bamboo fiber, and the core yarn is blended with 70% hemp and 30% cotton, wherein the outer covering yarn and The weight ratio of the core yarn is 9:11. The preparation method comprises the following steps: (1) preparing outer covering yarn; (2) preparing core yarn; (3) core-spun and spinning process; (4) winding process. The fabric made of bamboo fiber and hemp core-spun yarn can be used to prepare a three-piece summer mat. Green and environmentally friendly bamboo fiber is used as the outsourcing fiber to make full use of the hygroscopicity, air permeability and easy coloring of bamboo fiber. At the same time, hemp is used as the core yarn, which will not damage the softness and smoothness of the bamboo fiber, and it is comfortable to wear next to the skin. Style, and improve the performance of hemp yarn, play a reinforcing effect in the fabric, make up for the characteristics of low strength and poor shape retention of bamboo fiber.

Description

technical field [0001] The invention belongs to the field of textile weaving, and in particular relates to a bamboo fiber hemp core-spun yarn and a preparation method and application thereof. Background technique [0002] In today's resource shortage and serious environmental pollution, energy saving, environmental protection and sustainable development have become the development trend of the 21st century. The innovation focus of textile raw materials has shifted from purely differentiated synthetic fiber development to high-performance synthetic fiber and natural resource fiber, to realize the optimal utilization of sustainable natural resources, and to innovate the textile industry on the main line of ecology and environmental friendliness. It has become an inevitable trend in the future development of the textile industry. [0003] Bamboo fiber is a green and environmentally friendly material extracted from raw bamboo. It has bamboo's natural anti-mite, anti-odor, anti-...
