The important role of carding machine opening roller on fiber damage

Author:Xinjinlong Machinery-Fabric Recycling Machine Manufacturer

Damaged fibers are present in the opening roller card, in the opening roller carding fiber opening, carding and these phenomena zigzag shape and gold regarding the structural quality when using the opening roller carding machine in the presence of damage and phenomena surrounding fibers. 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. 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 further investigate the damage to fiber cells caused by the carding roller, West Germany has conducted a test on the BD-200 carding machine. When spinning synthetic fibers and fibers, the carding machine carding brocade adopts a saw blade with a thin white distance. , while for cotton and man-made fibers, the carding series uses a saw blade with a tighter pitch. The test results are shown in circle 58, which lists several problems of fiber shortening in the carding process, and the degree of fiber shortening related to the variety of fiber products, different fiber lengths, sawtooth structure shape and carding speed control. data.

The percentage (%) on the ordinate is the average length and feed of the fibers in the spinning rotor.λThe quotient of the average fiber length of the sliver, 100% means that the original fiber stiffness of the enterprise remains unchanged, and 80% means that 20% of the fiber length can be damaged by worms during opening. The abscissa is the carding speed and the revolutions per minute. The Ilh knots in Figures 8-50 are the number of fibrous tissue-fibrous long skin curves compared to the analysis in the previous figure.

From the above test results, it can be seen that some chemical fibers (such as polypropylene wax fibers) have almost no length loss after carding and loosening, correspondingly, especially polymerase fibers, even when the method of opening and maintaining the fibers is used. The length of the fibers is also greatly damaged. Furthermore, under the same working conditions, fiber damage is related to fiber length, serration shape and carding speed.

The graph above shows the distribution of fiber lengths obtained from these procedures. The solid line is the distribution of the fiber length in the strip, the dotted line and the dot are the distribution of the fiber length in the yarn cup, the dotted line is the synthetic fiber type saw blade, and the cotton saw blade is used for counting money. The special strength of polypropylene wax is noteworthy.

Allegedly, when the auxiliary blade is serrated aluminum deep carding, it will cause the phenomenon of constant stick around the point, and thus produce a common yarn unevenness.
