Problems solved by technology

However, the hemp fiber itself has poor fiber length uniformity, spinning evenness and unsatisfactory hairiness. After dyeing, fiber breakage, main body length becomes shorter, fiber strength decreases, and fibers are entangled and difficult to loosen. , the spinnability is severely reduced

Embodiment

[0018] A spinning method of color spinning hemp / cotton blended yarn, the dyed hemp fiber and cotton fiber are blended into yarn according to the weight ratio of 40-50:50-60, which specifically includes the steps of :

[0019] Cotton opening and cleaning process: FA002 disc bale grabbing machine is used to grab raw materials, FA002's thugs protrude from the ribs by 3.5mm, and the thugs drop intermittently by 4mm. Then, the FA105A single-axis flow opener removes impurities, the A035F automatic cotton mixer mixes, and the FA046 vibrating cotton box feeder sends the cotton flow to the A076F single-hand lapping machine to make cotton laps, with a weight of 440g / m.

[0020] Carding process: Feed the laps to the FA231 carding machine for carding and impurity removal to make raw sliver with a weight of 20g / 5m. Adopt the principle of "small quantitative, medium distance, low speed", adjust the five-point distance between the cylinder and the cover plate to 0.22, 0.2, 0.18, 0.18, 0.2mm...

Abstract

The invention discloses a spinning method of spun-dyed hemp / cotton blended yarn. The blended yarn is prepared by spinning the yarn which is formed by blending the dyed hemp fibre and cotton fibre at a ratio of (40-50):(50-60). The spinning method specifically comprises an opening picking process, a cotton carding process, a drawing process, a roving process and a spinning process, wherein the opening picking process is as follows: the dyed hemp fibre and the cotton fibre are manufactured into lap or cotton stream; and the cotton carding process is as follows: the lap or cotton layer is fed into a carding machine to be prepared into cotton strips, five-point gauge between a cylinder and a cover board is 0.22mm, 0.2mm, 0.18mm, 0.18mm, 0.2mm respectively, the rotation speed of the cylinder is 330-360r / min, and the speed of discharging strips is 65-75m / min. The blended yarn produced by the spinning method has bright color and has the advantages of good sterilization bacteriostasis and good wet-absorbing sweat-discharging property, and is a novel generation environment-friendly product.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a spinning method of color-spun hemp / cotton blended yarn. Background technique [0002] Hemp fiber is a natural fiber with good moisture absorption and release properties, antibacterial and antibacterial properties. Products made of hemp are breathable and sweat-wicking, mildew-proof and moth-proof, and have no stimulating effect on human skin, so they have good market prospects. At the same time, hemp is an annual herbaceous crop with strong adaptability to the living environment. It can use hilly, saline and other land without occupying cultivated land, and does not need to use pesticides during the growth process. It is in line with the current social green environmental protection, circular economy, resource conservation and sustainable development requirements for sustainable development. However, the hemp fiber itself has poor fiber length uniformity, spinning evenness an...
