The pile height generally refers to the distance from the bottom cloth surface to the top of the pile on the blanket surface. Controlling the pile height is nothing more than increasing or reducing this distance. Because the base fabric is walking on the comb-shaped pallet, adjusting the height of the pallet is equal to adjusting the height of the base fabric. In addition, the corresponding position of the top of the loop is at the position where the looping hook hooks the yarn, and the position of the looping hook can also be adjusted by the cross bar and the sector in the rocking shaft of the tufting machine. Two methods to adjust the distance between the loop and the base fabric can be determined from the size of the tu. In addition to the above conditions, the adjustment of the pile height must also be matched with the length of the pile yarn feeding, which
can be solved by speeding up or slowing down the speed of the yarn feeding roller. At the same time, it also maintains a certain tension of the pile yarn during the loop forming process.
The pile height of a tufting machine is controlled at 2~8m/h, and some commercial carpets require more than 15m/h. The adjustment of the loop height is also one of the important means to adjust the quality of the square meter pile yarn. .
