Embodiment Construction
[0015] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0016] Embodiments of the invention include:
[0017] A manufacturing process of wet-spinning core-spun yarn, the first step, beam splitting: the roving raw material is manually divided into bundles, the weight of each bundle is 120g, and the length of each bundle is 700mm;
[0018] The second step, combing and combining: put the bundled roving raw materials in the previous step into the combing and combining machine to make hemp strips;
[0019] The third step, drawing: the above-mentioned every five hemp strips are combined into a coarse hemp strip;
[0020] The fourth step, roving: on the roving frame, the hemp sliver in the previous step is made into roving;
[0021] The fifth step, pectin...

The invention discloses a manufacturing technology of wet spinning core spun colored spun yarn. The technology comprises the first step of bundling, the second step of combing and forming combination,the third step of drawing, the fourth step of roving, the fifth step of pectin removal, wherein pectinase is added into water, and roving is placed for boiling for 1 h; the sixth step of core spinning, wherein wet roving obtained after pectin removal sequentially passes through a feeding roller and a drawing roller, a yarn guiding hook is arranged between the feeding roller and the drawing roller, dyed elastic polyester fiber is placed on a bobbin hanger, the elastic polyester fiber is pulled out to penetrate through the yarn guiding hook and enter the drawing roller together with the roving,the roving and the elastic polyester fiber are drawn out from the drawing roller and then twisted, and finally covering yarn is formed; the seventh step of drying, the eighth step of spooling and theninth step of packaging. In this way, the obtained coring yarn is exquisite in appearance and diversified in color, and structurally has better elasticity and strength compared with single linen fiber; the wet spinning technology can ensure the product structure firmness and reliability, and is high in manufacturing efficiency.
Description
technical field [0001] The invention relates to the field of flax production, in particular to a production process of wet spinning core-spun yarn. Background technique [0002] As a pure natural fiber, flax has the remarkable characteristics of sweat absorption, good air permeability and harmlessness to the human body. The color is single and the structural characteristics of the product are fixed, which cannot meet the needs of the existing market for diversified products. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide a wet-spun core-spun yarn production process, which can wrap the original linen thread with elastic polyester (PTT) and other materials to make a core-spun yarn. The appearance of the core-spun yarn is Exquisite, diverse colors, the structure of the product is more elastic and stronger than a single flax fiber; this wet spinning process can ensure that the product structure is firm and rel...
