Technical Field

The invention belongs to the technical field of spinning, and particularly relates to a weaving device and a weaving method of a double-sided integrated cut pile fabric.

Background

A circular knitting machine, known as a circular weft knitting machine, has the advantages of multiple looping paths, high rotating speed, high yield, fast pattern change, good fabric quality, few working procedures, strong product adaptability and the like, and is widely applied to the knitting industry. Circular knitting machines include single-face circular machines and double-face circular machines, which have two needle cylinders, an upper needle cylinder (known as dial), a lower needle cylinder, and are arranged vertically to each other, i.e. the dial and the needle cylinders are arranged vertically at 90 degrees.

The double-faced fabric is a braided fabric, in the process of braiding the double-faced fabric in the prior art, napping and raising treatment are carried out on the double-faced fabric, napping needs to be carried out on specific napping equipment, and the double-faced fabric subjected to napping treatment can cause disorder and easy falling of reverse side yarns, so that the quality of the double-faced fabric is affected.

In order to solve the above problems, for example, the invention with the publication number of CN105696183B discloses a double-sided knitting and shearing integrated machine, which includes a frame, a cylinder, a dial, a lower needle groove vertically extending on the outer peripheral surface of the cylinder, an upper needle groove radially extending on the upper end surface of the dial, an upper knitting needle and a lower knitting needle movably arranged in the upper needle groove and the lower needle groove, and an upper cam and a lower cam for driving the upper knitting needle and the lower knitting needle to cooperate to complete knitting.

However, the double-sided knitting and shearing all-in-one machine realizes pile cutting by additionally arranging the shearing mechanism, and compared with the existing double-sided circular machine, the double-sided knitting and shearing all-in-one machine is complex in structure and difficult to control.
