The preparation process of the comfortable linen-like knitted fabric comprises the following steps:

[0050] S1. Surface modification of viscose fiber: prepare a 1.0 mol / L methyl methacrylate solution with a pH value of 6.0 to 6.3, put the viscose fiber into the solution and keep it in a water bath at a temperature of 70°C for 120 to 150 minutes, then take out the viscose fiber after the reaction, dehydrate and dry it;

[0051] S2, spinning: blending the surface-modified viscose fiber obtained in S1 with the acrylic staple fiber to form a first yarn, and blending the slub cotton with the cotton fiber to form a second yarn;

[0052] S3, yarn steaming and weaving: steaming the second yarn obtained in S2 for 10 to 20 minutes at a temperature of 55° C. to 60° C. and a pressure of 0.04 MPa to 0.06 MPa, and then weaving the second yarn with the first yarn in S2 into a grey cloth using the circular knitting machine body (11) and leading out;

[0053] S4, dyeing and shaping: dyeing the grey cloth obtained in S3, and introducing the dyed fabric into a shaping machine for shaping, wherein the temperature in the shaping machine is maintained at 120° C. to 150° C., and the conveying speed of the fabric in the shaping machine is maintained at 10 m / min to 15 m / min. After shaping, the linen-like knitted fabric is obtained.

[0054] By adopting the above technical scheme, the viscose fiber is first placed in a methyl methacrylate solution for reaction for modification, thereby improving the skin affinity and softness of the viscose fiber, so that the knitted fabric made of the viscose fiber can have better feel and comfort; then the modified viscose fiber is blended with the acrylic staple fiber to form a first yarn, and the bamboo cotton is blended with the cotton fiber to form a second yarn. The first yarn and the second yarn are steamed and woven into a grey cloth using a circular knitting machine. The steaming improves the weaving force of the first yarn and the second yarn, thereby improving the flatness and texture of the knitted fabric; finally, the grey cloth is dyed and shaped to obtain the desired linen-like knitted fabric.

[0055] In summary, the present application includes at least one of the following beneficial technical effects:

[0056] 1. After the fabric is output from the circular knitting machine body, it is stacked in the fabric box. The weighing table weighs the weight of the fabric box. When the weight of the fabric in the fabric box reaches the preset value of the weighing table, the weighing table transmits a signal to the controller. After receiving the signal from the weighing table, the controller controls the drive component to start, and the drive component drives the cutting knife to cut the fabric. Therefore, the staff does not need to observe the output of the fabric at all times beside the circular knitting machine and cut it manually, which reduces the work intensity of the staff and improves the work efficiency.

[0057] 2. The moving rod is driven to move by starting the moving assembly, and the movement of the moving rod drives the cloth-placing rod to swing back and forth. The reciprocating swing of the cloth-placing rod makes the fabrics stacked in the fabric-placing box in an orderly manner, thereby reducing the probability of uneven stacking of fabrics in the fabric-placing box and improving the space utilization rate in the fabric-placing box;

[0058] 3. By setting an arc-shaped guide surface on the top surface of the limit block that passes through the limit groove, the side wall of the cloth box contacts the guide surface when the cloth box moves horizontally. The guide surface generates a component force that drives the limit block to move into the limit groove to move the limit block into the limit groove, thereby eliminating the need to manually compress the limit block into the limit groove, thereby improving work efficiency.
