[0049] Described production method comprises the steps:

[0050] Cleaning and carding process: long-staple cotton → JWF1009 reciprocating plucking machine → JWF0007 heavy object separator → JWF1107 single-axis flow opener → JWF1029 multi-compartment blender → JWF1115 fine opener → CCH- Type II foreign fiber separator → JWF1171 type feeding box → JWF1203 carding machine; in the cleaning and carding process, the beater speed of the JWF1009 cotton picker is 700r / min, and the beater speed of the JWF1115 cotton opener Speed ​​is 580r / min, and beater adopts comb-type beater; The raw sliver quantitative of long-staple cotton is 18.0g / 5m; The cylinder speed of described JWF1203 type carding machine is 360r / min, and the licker-in spee...

Embodiment 2

[0058] A kind of production method of extra-fine special yarn, long-staple cotton selects grade 2 Xinjiang long-staple cotton, micronaire value 4.35, fineness 1.73dtex, average length 37.5mm, uniformity 88.0%, short-staple rate 6.2%, neps 135 Grains / g.

[0059] Described production method comprises the steps:

[0060] Long-staple cotton pretreatment: first spray the long-staple cotton with hot steam, then spray the long-staple cotton with an antistatic agent, and then dry the long-staple cotton at a temperature of 40°C and a humidity of 75% for 1 hour , and then continue to dry for 3 hours in a ventilated natural environment. The composition of the antistatic agent is 1wt% polyethylene glycol, 1%wt salt, 0.5wt% tea saponin, 10wt% ethanol, and the balance is water.

Abstract

The invention relates to the technical field of spinning, and discloses a method for producing extra-fine yarns. The method includes a scutching and combing cotton step by subjecting long stapled cotton to a JWF1009 reciprocate plucker, a JWF0007 type weight separator, a JWF1107 type single-axial flow cotton slitter, a JWF1029 type multi-barn cotton blender, a JWF1115 type fine cotton slitter, a CCH-II type irregular fiber separator, a JWF1171 type feeding hopper and a JWF1203 type carding machine, a combing step completed by a FA306 type drawing frame, a JSFA360 type sliver lap machine and a JSFA388 combing machine, a drawing step completed by an FA326 type drawing frame, a roving step completed by an FA458 type flyer frame, a spinning step completed by a DTM129 type spinning machine, and a winding step completed by an autoconerX5 type automatic spooler. The method ensures low fiber damage level of long stapled cotton, and less short fiber contents and neps impurities and extra-fine yarns produced are high in quality.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a method for producing ultra-fine yarn. Background technique [0002] Ultra-fine yarn refers to yarns of 10tex and below (58 British counts and above), which are suitable for high-end fine fabrics, such as high-count shirts, worsted close-fitting woolen sweaters, etc. [0003] Ultra-fine special yarn is generally made of long-staple cotton as raw material, which is prepared successively through cleaning and carding process, combing process, drawing process, roving process, spinning process and winding process. Relatively low, it is difficult to control evenness, thick places, fine details and neps. And in the technology of prior art, the damage degree that long-staple cotton fiber receives in each working procedure is bigger, easily produces short staple, and nep impurity is more, has influenced the final quality of product. Contents of the invention [0004] In order to sol...
