Embodiment 1

[0014] Embodiment 1 Carding 32 S yarn production

[0015] (1) Cleaning and carding process: the cotton is passed through the cleaning and carding unit produced by Qingdao Textile Machinery Factory to remove impurities, neps, and short fibers, and card cotton fibers;

[0016] (2) Drawing process: the cotton fiber obtained in the previous step is drawn by the Baohua brand drawing frame produced by Baoji Textile Machinery Factory to obtain a uniform sliver for further impurity removal;

[0017] (3) Roving process: the uniform sliver obtained in the previous step is passed through the FA458 roving frame produced by Tianjin Textile Machinery Factory, the sliver is elongated and thinned, shaped, and formed into a semi-finished yarn;

[0018] (4) Spinning process: the semi-finished yarn obtained in the previous step is further elongated and thinned by the FA506 spinning machine produced by Shanghai No. 2 Textile Machinery, and the finished yarn is produced as required;

Abstract

The invention provides a method for producing purified cotton yarns, which is characterized by comprising the following steps: (1) a process step of blowing-carding; (2) a process step of drawing; (3) a process step of roving; (4) a process step of fine spinning; (5) a process step of spooling; and (6) a process step of packaging. The method optimizes the production process steps of the purified cotton yarns, the produced purified cotton yarns accord with the national standard, the single yarn strength evenness CV percent value is good, the end breakage rate is low, and the yarn quality is stable.

Description

technical field [0001] The invention relates to a production method of yarn, in particular to a production method of pure cotton yarn, and belongs to the technical field of textiles. Background technique [0002] Pure cotton yarn is made from cotton and produced by spinning machines, including carded yarn and combed yarn, which are mainly used to produce pure cotton products. Pure cotton products have the following advantages: ①Good hygroscopicity;② It has good moisture retention; ③Good heat resistance; ④High resistance to alkali; ⑤There is no stimulation and no negative effect in contact with the skin. It is beneficial and harmless to the human body after long-term wearing, and has good hygienic performance. Therefore, pure cotton products are deeply loved by people and have a wide range of uses, which leads to a relatively strong demand for pure cotton yarns. [0003] At present, the problems in the production of pure cotton yarn are low single yarn strength, poor evennes...
