Cotton production and the beginning of cotton work

Cotton production and the beginning of cotton work. Carding machines are used to process cotton fibers and chemical fibers and belong to textile machinery. According to the spinning process, carding is an important process.

The front process of the carding machine is the opening and cleaning machine, and the latter process is the drawing frame (carding process) or the sliver coiler (combing process). The structure of the double twisting unit of the double twisting machine mainly includes the spindle braking device, the spindle part of the double twisting machine, the yarn winding device, and the special device of the double twisting unit. During the spinning process of the spinning frame, the semi-finished roving or sliver is drafted, twisted, and wound into a spinning machine. The combed sliver and the needle-carding machine combine the sliver, the needle row is drafted to improve the sliver structure, and the roving is further spun into spun yarn on the ring spinning frame, which is the main spinning machine.

With cotton work is to pay attention to stable production, good product quality, but also consider reducing the cost of cotton circulation to improve economic benefits. Use more than 80% of the total cost of cotton. Below Xiaobian Hong Co., Ltd., St. combing cotton common sense to talk about you.

1. The formulation of cotton composition At present, the analysis of cotton composition in each factory is formulated by the cotton spinning company. According to the actual inventory of cotton, each factory will determine the specific active ingredients of the factory by referring to the company's management regulations. It is handed over to the cleaning workshop to implement it conscientiously. Production practice has proved that the formulation of cotton ingredients should take into account the content of Table 2-B. 2. Knowledge of batch receiving Due to cotton raw materials, it is impossible to supply a large amount of cotton leather for a long time, so it is necessary to save a lot of cotton.

Control for coverage differences between blended cotton and Pingmei index. In production practice, then the composition difference of batch adjustment should be: the regional difference does not exceed 30%, the length does not exceed 0.5mm difference, the fineness difference metric count does not exceed 200, the grade does not exceed 0.4 difference, impurities Content is not more than 0.50%, the number of harmful impurities can not afford Di 400, can not afford more than 1.5% is a suitable jar. 3. Several specific examples for our reference (1) Yarn with a length of impact strength The length of cotton fiber, each sheath 1 mm increase in body production practice filament, the yarn strength can be increased by about 3.8%.

However, length uniformity is more important because it not only has a strong influence on Miao, but also on the uniformity of the sliver. The degree of neatness and regularity of the length has been expressed by Jijing. Even if the Zhukov fiber analyzer is used, when the button distance is 1 mm, the fiber is divided into five adjacent groups including the different lengths of the student body and the percentage of the total amount.

Length uniformity = body length×The basic uniformity is generally mastered by students at 800~1200o, and the yarn strength can be increased by more than 2.2% for every 100 increase in the uniformity. There is a reference value for the relationship i between the yarn unevenness and the uniformity, as shown in Table 2-6. In this regard, a factory once used a mixing uniformity of 1000. When the cotton matching length can be selected from 27.5 mm of knitted single jersey No. 18 (32 inch), the quality evaluation index system is still above 2350, and the USTER is even. The uneven rate is 14%, and the blackboard is more than the income level.

(2) The number of fibers The higher the number of fibers in the cross-sectional thickness of the yarn with a more specific number of fibers, the higher the contact area between fibers, the friction between each insertion resistance will increase, reducing the effect of sliding , therefore, the yarn is increased by the force. Practical blending components obtained, for every increase of 400 fiber counts of common support, the yarn quality fingerboard increased by about 3% (transferred cotton fiber branching sensitive element 5000 is common support above). The number of fiber cores has a direct effect on the uniformity of the yarn.

The examples demonstrate that when the fiber count is increased from 5000 to 5600 known as branched rods, the drying on the blackboard can be biased and can reduce the rate cycle by 0.7%. (3) Machine separation and reverse treatment machine separation and multi-combination affect the fly number of knots in the yarn. In production, when we encounter more than 3.5% impurities in the machine, we often stop learning to use the batch of raw cotton or carry out the reverse treatment of the whole line of cotton cleaning machines.

However, attention should be paid to whether impurities can be removed in the steel cleaning process. For example, a factory uses Pakistani cotton with a 4% impurity content.
