The tasks of the carding process

(1) In the cotton lap or cotton layer that can be made by carding the raw cotton through the opening and cleaning process, the fibers are mostly bundles and blocks, and the average weight is generally between several grams and tens of milligrams. 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. Grinder A spinning machine that turns fiber strands into rovings.

The main function is to draft and twist, and to wind the roving into a certain package to meet the processing requirements of the spinning frame. 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.

Therefore, we are required to further develop and analyze in detail, so that bundles and lumps of fibroblasts can be separated into single fibrous tissue. (2) The impurities and defects in the impurity-removing raw cotton can only be removed by about 60% in the process of opening and eliminating cotton. Most of the impurities remaining in the lap or cotton layer are some small impurities with fibers or strong adhesion. Such as fibrous seed chips, quilt seeds, soft seed bag skins and brocade knots, etc., we must continue to work hard to eliminate them. (3) The mixing and uniform opening and cleaning steps are used for different characters and proportions of raw cotton, which only have a preliminary mixing effect, and a single card can be fully mixed to the fibers.

The comb-like member of the carding machine also has some“suction”, fibrous“freed”nature and therefore more uniform sliver of the child. (4) In order to facilitate the continuous development and processing of the next process, the fibers should be gathered into strips, and a certain regular map should be stored in the cotton sliver. The degree to which the tufts on the card are separated into individual fibers is closely related to the drafting, yarn tenacity and stripping of the later process.

The effect of the card to remove impurities largely determines the knot and drying of the yarn. The brocade drop rate of the carding machine is the most in the preparation process, and it contains a certain amount of spinnable fibers, so the quantity and quality of the cotton droplets are reasonably controlled. Straight money is related to the amount of cotton per piece of yarn.
