Card Noil Test

Author:Xinjinlong Machinery-Fabric Recycling Machine Manufacturer

(1) Test the noil condition of the carding machine, determine the noiling condition, master the noil removal condition of the carding machine, and provide a reference for the improvement of the process and machinery. 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. 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.

Special equipment for the textile industry on the winder. As the last process of spinning and the first process of weaving, winding is the link between the past and the next.“bridge”Therefore, it occupies an important position in the textile field. In order to balance the blanking speed of the bottom or cover and adjust the process in time, a single quick test of the blanking speed of the bottom or cover can be performed in combination with the wiping cycle.

(2) All cotton noil tests are carried out at least 4 times a month for each variety. The flat belly fast single-item noil test cycle is usually once a month, which can be combined with the wiping cycle for timely adjustment. (3) Test method (1) The test machine first takes out the needle, takes out the cover plate noil, takes out the car noil, and completes the cleaning work.

(2) Cover the front and rear sides of the car with kraft paper or plastic sheeting to place dropped plums. The test must be carried out after the straw has been blocked or sealed by the automatic suction device. (3) After weighing and recording the weight, send the roller into the starter car.

(4) Generally test 1 to 2 laps or 1 to 2 slivers, and also test a cycle. After reaching the specified time, close the carriage, clean the drum and doffer, peel off the needle cotton, take out the flat cotton, take out the belly cotton, weigh and sample separately for noil analysis, and simultaneously take the cotton ring and sliver for impurity content analysis. (5) A single rapid measurement can be used to detect a roll of cotton or a certain number of machines within a certain period of time (such as 3 hours) without a needle. Generally, it is only used for the comparison of the drop rate, not for the analysis of the drop rate and impurity rate. However, if If the content of the machine is found to be abnormal, white flowers should be recorded.

(4) Calculation of test data. Test data can be processed in the form of Table 5-2. The calculation model formula is the same as the basic situation of the open-carding machine noil test research. According to the relevant test and analysis methods, the feeding weight and the available feeding lap weight, or using (made sliver weight + back flower weight + noil weight) weight).

Among them: the same test of transformation noil and carding, if necessary, analysis of heteroatom content in hand-picked Tsumugi. When doing the noil test of the blower-carding machine, the blow-cleaning part and the carding part should be carried out at the same time. We should study the total weight of the raw sliver and the total waste of each blowing and carding machine at the beginning of the feeding weight, and then add the weight of the return pattern and the return sliver.
