Problems solved by technology

Its disadvantages are: because the leftover material has been through the spinning process, its strength is low and it is easy to generate static electricity; and because the fiber length of the leftover material is much smaller than the length of cotton fiber used in making cotton fiber yarn, the recycled fiber poor cohesion between
Due to the poor spinnability and small size of the recycled fiber, it is generally treated as a waste product directly without secondary processing, resulting in waste of raw materials

Embodiment Construction

[0013] The method for producing all-cotton floral yarn of the present invention is characterized in that it comprises the following steps in sequence:

[0014] Step 1, the raw material treatment process, injects oil on the recycled fibers to reduce static friction; the smaller the static electricity, the cohesion between the recycled fibers can be increased, and the crimp of the recycled fibers can also be reduced.

[0015] Step 2, cleaning and carding process, using Trützschler cleaning and carding unit, its parameters are set as follows: licker-in speed 1050rpm / min, cylinder speed 510rpm / min, movable flat speed 170mm / min, doffer speed 850rpm / min, carding speed 100m / min, flat and gauge 8 / 1000, 9 / 1000 or 10 / 1000 inch, cylinder and licker-in roller gauge 7 / 1000 inch, cylinder and doffer gauge 6 / 1000. Among them, rpm / min means how many revolutions per minute, and m / min means how many meters per minute. In this process, the principle of "more mixing and earlier falling, more ...

Abstract

The invention discloses a method for producing all-cotton lap waste yarns. The method sequentially comprises the following steps of: (1), treating raw materials; (2), blow-carding; (3), drawing; (4), preparing rovings; (5), preparing spun yarns; and (6) obtaining a bobbin. By the method for producing the all-cotton lap waste yarns, lap waste fiber can be used for manufacturing cotton threads.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a method for producing all-cotton patterned yarn. Background technique [0002] Cotton thread is generally made of cotton fiber. Back flower fiber refers to the leftover material after various processes when cotton fiber is used to spin cotton thread. For example: after the drawing process, roving process, and spinning process, the scraps are cut. Its disadvantages are: because the leftover material has been through the spinning process, its strength is low and it is easy to generate static electricity; and because the fiber length of the leftover material is much smaller than the length of cotton fiber used in making cotton fiber yarn, the recycled fiber The cohesion between them is poor. Due to the poor spinnability and small size of the recycled fiber, it is generally treated as a waste product without secondary processing, resulting in a waste of raw materials.
