Description
Technical Field
The invention relates to the technical field of carding machines, in particular to card clothing of a carding machine suitable for producing non-woven fabrics and a preparation method thereof.
Background
The carding machine is the heart of the fiber processing of the spinning mill, and the card clothing is the heart of the carding machine, is a key equipment for carding machines, silk spinning carding machines, combing machines, gilling machines, rotor spinning machines, non-woven carding machines, fluffing machines and the like, and the development of the carding machine is closely linked and complementary with the development of the carding machine. The development of carding machines, which continuously put new demands on card clothing, has further promoted the development of carding machines, and without the development and application of metallic card clothing, it is impossible to have today's high speed and high production carding machines. The emergence of new fibers also puts new requirements on card clothing, and greatly promotes the technical progress of card clothing. Card clothing is divided into two major categories, elastic card clothing and metal card clothing, and elastic card clothing is mainly used for rotary flat of woolen carding machines, napping machines and carding machines. The elastic card clothing has been applied to carding machines for hundreds of years, and plays a great promoting role in the development of the carding machines. The card clothing is classified into elastic card clothing, semi-rigid card clothing, metal card clothing, and the like. At present, elastic card clothing is mainly used for rotary flat plates of card machines, carding machines and carding machines. Metallic card clothing is used in various carding machines, and is gradually replacing elastic card clothing.
The disorder is that after the fibers pass through a disorder roller which runs at a high speed, the direction of part of the fiber arrangement is shifted due to the vortex airflow of a disorder triangular area, so that a fiber web with non-oriented fiber arrangement is formed. The transfer of fibers from the dancer roll to the doffer is typically through the dancer roll, which results in a web with a higher degree of dancer and a closer strength in the cross-machine direction. When the fibers are long, the disordered triangular area is small relative to the fibers, which is beneficial to the disorder of the fibers.
The high-yield carding machine has high yield, high speed, high card clothing loss and high quality fluctuation, and increases the setting difficulty of gauge. The accuracy of the cotton carding gauge is embodied in the gauge qualification rate, namely the ratio of the qualified gauge number to the total gauge number, in the actual operation, a checking method similar to the process on-machine qualification rate is adopted, and the gauge qualification rate of the gauge is calculated by sampling and checking a certain number of machine gauges. In the prior art, the gauge of the card clothing is small, the checking operation of the gauge qualification rate is complex, the damage of the card clothing to long fibers is large, the disordered effect is not ideal enough, and the card clothing is not suitable for producing high-quality non-woven fabrics.
