Carding requirements for card clothing

Author:Xinjinlong Machinery-Fabric Recycling Machine Manufacturer

Cylinders, doffers and covers have initially licker-in combed cotton and loose fibers into bale-to-comb detailing two steps, and some impurities are removed. 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.

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. The comb-doffer cylinder on the fiber layer condenses into fibers, combs and cohesively, and the fibers are combined to obtain a homogeneous mixture.

These combed, trash, cotton and blended, fibers are all associated with the character's clothing. The needle face of carding has the ability to hold the fibers, so there is a certain amount of fiber on the needle face when carding, which is generally called the needle face load. The needle face load reflects different clothings (types of clothings, specifications and the state of their needle teeth).

The forces of different process parameters (gauge and surface speed ratio) on fiber holding, carding and transfer. There are the following two different fibers in the needle surface load operation, one is the inner layer and fibers that are submerged in the land between the needle teeth, and the other is the free-going fibers floating on the tip of the needle teeth. However, the total needle surface load is related to the analysis of factors such as the type of card clothing company, specifications, needle tooth status, output per hour, and the distance between Xinjinlong cover and doffer.

Card clothing should have the following properties: 1. Needle teeth must be sharp. When making card clothing, regardless of the product type and how it is, it should have high sharpness to have a good ability to pierce and grab fibers for the development of different fibers. , so that the fiber can often be at the tip of the needle by itself, so that students can study the active opening of the two opening needles. This kind of sharpness must be durable, the well can withstand grinding (flat grinding and side grinding), and the sharpness must keep the surface smooth and flat without hooks, so as to improve the transfer of fibers without causing serious flower hanging. The leveling is to adjust the tight spacing and create a good environmental condition for the carding transfer enterprise.

2. It has a certain inter-needle capacity and good ability to absorb and release fibers. The fibers can be transferred well between the cover Jinlin Read and Xin Jinlong Daofu, which can not only effectively reduce the load on the needle surface, but also improve the free carding of students. efficiency, thus also improving the quality of the carding. 3. Strong adaptability In the carding machine equipment, there is the task of spinning multi-variety yarns and chemical fiber and other fiber blended or pure spinning yarns, while the carding machine is a multi-machine equipment, and the adaptability of the card clothing must be wide. Otherwise, with the change of varieties and raw materials, it is not economical and cannot be used in practical work.

In order to meet the needs of economical, high-speed, high-yield and various chemical fiber processing, metal card clothing companies have developed rapidly in China. Elastic card clothing has a long history of use, and it is still applicable to finer yarn carding in my country. MCC is usually rolled flat wire, made from stamping, quenching, such as needle bar.

The finished cord is bent into a U-shaped wire with fine resolution, according to a certain tissue explant on the base fabric, the knee is bent, laterally ground, ground pressure and quenched. Compared with the two, each has advantages and disadvantages: based on the comparison of the above analysis performance, the efficiency of the high-yield carding machine is high, the speed of Xinjinlong and Doffer is fast, and the quantitative influence of the line is relatively heavy, so it is necessary to wrap the metal card clothing, In the spinning of fine commercial yarn counts, the ration is light, and the product design requires the quality of the enterprise to be consistent, and elastic card clothing is preferred. Of course, due to the continuous development and improvement of the material, tooth shape and specifications of China's metal card clothing, there will be more research on the application of metal card clothing in the future.
