Embodiment 1

[0031] A kind of bamboo fiber hemp core-spun yarn of the present invention comprises outer covering yarn and core yarn, and outer covering yarn is made of bamboo fiber, and core yarn is formed by blending of 70% hemp and 30% cotton, wherein, the outer covering yarn and core yarn The weight ratio is 9:11.

[0032] Its preparation method comprises the following steps:

[0033] (1) Preparation of covered yarn

[0034] A, select a certain amount of bamboo fibers according to the process requirements, and through the cotton opener process, then adopt the vibrating cotton box cotton feeder to feed cotton, and open into cotton laps by the coiler, wherein the beater speed of the cotton opener is 400r / min, the beater speed of the vibrating cotton box feeder is 150r / min;

Abstract

The invention discloses bamboo fiber-hemp covering yarns comprising cladding yarns and core yarns. The cladding yarns are made of bamboo fiber, the core yarns are made by blending 70% of hemp and 30% of cotton, and the cladding yarns and the core yarns are in 9:11 in weight ratio. A production method of the bamboo fiber-hemp covering yarns includes 1, producing the cladding yarns; 2, producing the core yarns; 3, performing core spinning and fine spinning processes; 4, performing spooling process. According to the arrangement, fabrics made of the bamboo fiber-hemp covering yarns are applicable to three-piece mat production; as the cladding fiber, the green and environmental bamboo fiber is fully used in moisture absorption, air permeability and coloring proneness; with the hemp as the core yarns, not only are the soft, smooth and good skin-touch characteristics of the bamboo fiber maintained, but property of the hemp yarns is improved to strengthen the fabric, and defects of the bamboo fiber of low strength and poor shape maintenance capability are remedied.

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-...
