Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textiles, in particular to a British wool low count yarn worsted processing method and fabric. BACKGROUND

[0002] British wool is a long wool breed, which is a good raw material for manufacturing woolen yarn, plush, blanket and industrial woolen fabric. The variety count is 46-50, the average diameter is 25-31 microns, the length is 11-15 cm, and the maximum length is more than 20 cm. The strength is 1.3-2.0 g / d.

[0003] The spinning process flow of carded wool spinning is relatively short, only "carding" and "spinning". The carded wool spinning machine realizes synchronous transmission of each motor of each unit group through a frequency converter control system, replacing the original mechanical method of front, middle and rear carding machine groups. One motor drives multiple gearboxes through a long shaft to achieve synchronous action between each other. The carded wool spinning machine has ring spinning and flyer spinning two forms. The new ring spinning occupies less area than the flyer spinning. Most domestic cashmere enterprises are equipped with Bigagli flyer spinning frame. The process flow is generally as follows: blending, carding, spinning, winding and twisting.

[0004] In the classification of yarn, the commercial habit is to call the yarn below 7 English count (11.8 Nm) as coarse count yarn. The commonly used machines in existing production are ring spinning frame and rotor spinning frame. Due to the limitation of special conditions, especially the limitation of steel ring and steel ring conditions, the ring spinning frame is generally difficult to produce coarse yarn below 6 English count (10.1 Nm), and it is impossible to produce ultra-low coarse yarn below 3 English count (5.1 Nm). The rotor spinning frame is also limited by its special conditions, and it is generally difficult to produce coarse yarn below 4 English count (6.8 Nm), and it is impossible to produce ultra-low coarse yarn below 3 English count.

[0005] Low count carded yarn needs to be produced by special equipment, and the equipment product variety is single. For wool spinning workshops, the production of this variety of yarn requires the purchase of new equipment, which brings higher production cost. The production process of ultra-low coarse yarn is different, and the field use of the fabric is also different.

[0006] The technical problem to be solved by the present application is to provide a British wool low count yarn worsted processing method and fabric, which realizes the production of low count carded yarn by worsted equipment and can be used for woven single warp and single weft worsted fabric. SUMMARY

[0007] To solve the above problems, the present application provides a British wool low count yarn worsted processing method and fabric.

[0008] The technical scheme adopted by the present application to solve its technical problems is: a British wool low-count yarn worsted processing method, comprising the following steps:

[0009] S1. Color matching: after the British wool is opened into a bundle, it is dyed, washed, and dried, and then color matching is performed;

[0010] S2. Roving: the roving process is performed according to the color matching process of S1, the first oil and water is added during the roving, and the bundle is stored in a bag after being taken out of the machine to ensure that the moisture regain is not lost;

[0011] S3. Three-draft gilling: the bundle obtained in step S2 is drafted, drawn, and combed through three-draft gilling to make the fibers straight and parallel, and the second oil and water is added;

[0012] S4. Re-combing: the straight wool obtained in step S3 is further subjected to a re-combing process to remove short fibers, neps, and grasses, and to obtain re-combed roving with uniform color and straight fibers;

[0013] S5. Two-draft gilling: the straight wool obtained in step S4 is fed into a two-draft gilling machine, the third oil and water is added, and the straight wool is packed into a ball after being combed and straightened;

[0014] S6. Front spinning two-draft gilling: the straight wool obtained in step S5 is further combed;

[0015] S7. Roving: the roving obtained in step S6 is drawn and thinned to a roving of the required gram weight for use in a spinning machine;

[0016] S8. Back spinning process: the roving obtained in step S7 is further drawn and twisted to obtain spun yarn, and the spun yarn is obtained after steaming and winding.

[0017] As an optimization, the amount of oil and water added in steps S2, S3, and S5 is 15% of the mass of the wool.

[0018] As an optimization, the roving count in step S7 is 1.2-2.4 ktex, and the spun yarn drawing multiple in step S8 is 12-14.4 times, the spun yarn twist is 280-420 twists per meter, and the obtained spun yarn count is 5-12 Nm.

[0019] As an optimization, the groove depth of the spinning roller used in step S8 is 2.0 mm, and the maximum gauge of the spinning gauge device is 220 mm.

[0020] As an optimization, the water and oil in steps S2, S3, and S5 include lubricating oil, antistatic agent, and water, and the ratio of the lubricating oil, antistatic agent, and water is 2:0.5:15.
