Production method for woolen yarns in count of 56Nm

Abstract

The invention relates to a production method for woolen yarns in count of 56Nm. The method includes steps: A, carding, to be specific, processing wool rolls through a carding machine, wherein the weight of a single rough yarn wool roll processed by the carding machine is controlled to be 0.044g / m; B, doubling, to be specific, adopting a doubling machine for doubling the rough yarn wool rolls processed by the carding machine, wherein the weight of a doubled stranded rough yarn wool roll is controlled to be 0.088g / m; C, roving, to be specific, subjecting the doubled rough yarn wool rolls to drafting twisting by a spinning roving machine, wherein the weight of a single rough yarn is controlled to be 0.022g / m after roving; D, mule spinning, to be specific, subjecting rough yarns to mule spinning on a mule spinning machine after roving, wherein the spun yarn weight is controlled to be 0.0178g / m after mule spinning, and the count is 56Nm; E, spooling. By adding of doubling and roving processes between carding machine and mule spinning processes, transition distribution is realized through the roving machine to further change the rough yarn weight, and yarn thinning is realized.

Description

【Technical field】 [0001] The invention relates to the technical field of spinning, in particular to a method for producing cashmere woolen yarn with a count of 56Nm. 【Background technique】 [0002] Cashmere has the advantages of light weight, softness, and good toughness. It is especially suitable for making underwear and light and high-grade knitted sweaters. The more soft, light and close-fitting the cashmere yarn is, the manufacturing process of cashmere yarn in the prior art is generally: carding machine->spindle->winding, usually using the belt wire in the carding machine to separate the fleece to control the thickness of the yarn, The width of the belt yarn is generally 9.5-9.8MM, and the narrowest one is only about 8.5MM at present. Due to the internal structure of the belt yarn, the width of the belt yarn cannot be adjusted smaller. Therefore, this kind of cashmere slubbing is controlled by adjusting the width of the belt yarn. The method of yarn fineness is o...

[0002] Cashmere has the advantages of light weight, softness, and good toughness. It is especially suitable for making underwear and light and high-grade knitted sweaters. The more soft, light and close-fitting the cashmere yarn is, the manufacturing process of cashmere yarn in the prior art is generally: carding machine->spindle->winding, usually using the belt wire in the carding machine to separate the fleece to control the thickness of the yarn, The width of the belt yarn is generally 9.5-9.8MM, and the narrowest one is only about 8.5MM at present. Due to the internal structure of the belt yarn, the width of the belt yarn cannot be adjusted smaller. Therefore, this kind of cashmere slubbing is controlled by adjusting the width of the belt yarn. The method of yarn fineness is only applicable to the production of cashmere slubbed yarn with a count of less than 42Nm, and due to the draft limitation of the spindle machine and the different spinning forms, it is impossible to produce cashmere slugged yarn with a count of 56Nm
