Technical Field

The invention relates to the technical field of spinning, in particular to a method for solving the problem of inconsistent weaving layering of a binding double-layer fabric.

Background

The current market provides a novel fabric, and a knotted double-layer fabric is woven by using a low yarn count, low density and special weaving process. In the tying double-layer fabric, a double-layer structure refers to an upper layer structure and a lower layer structure which are overlapped with each other and formed by respectively interweaving two groups of warp yarns and two groups of weft yarns; the binding means that the upper layer, the lower layer, the inner layer and the outer layer are connected into an integral double-layer structure by various connecting methods. The knotted double-layer fabric is deeply loved by consumers due to the soft and fluffy hand feeling, and is particularly suitable for underwear for infants and children and home wear for adults.

The upper layer and the lower layer of the normal knotted double-layer fabric are overlapped and uniform in cloth cover, but the upper layer and the lower layer of the layered cloth cover easily slide left and right in the weaving process, the layered inconsistent situation of the upper layer fabric and the lower layer fabric occurs, the cloth cover color is uneven after dyeing in the post-process, the cloth cover at the position with inconsistent layering shows an irregular watermark form, and the appearance quality of the fabric is influenced. There is therefore a strong need to address the delamination inconsistencies of such face fabrics.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: the method for solving the problem of inconsistent weaving layering of the binding double-layer fabric is provided, the problem of non-positioning layering of the binding double-layer fabric in the manufacturing process is solved by modifying a cloth supporting platform, changing a double-pressing roller into a single-pressing roller for reeling and reducing the tension of a cloth roller.

According to the method for solving the problem of inconsistent weaving layering of the binding double-layer fabric, when the binding double-layer fabric is woven, the cloth supporting table is made of the whole S-shaped steel, the double pressure roller is changed into the single pressure roller during cloth rolling, and the tension of the cloth rolling roller is reduced, so that the problem of inconsistent weaving layering of the binding double-layer fabric is solved.

In the tying double-layer fabric, a double-layer structure refers to an upper layer structure and a lower layer structure which are overlapped with each other and formed by respectively interweaving two groups of warp yarns and two groups of weft yarns; the binding means that the upper layer, the lower layer, the inner layer and the outer layer are connected into an integral double-layer structure by various connecting methods.

Wherein the preparation process of the cloth supporting table comprises the following steps: cutting S-shaped steel with a certain length, cutting a plurality of square holes at the position corresponding to the auxiliary jet of the loom, cutting a plurality of round holes at the middle part of the S-shaped steel, cutting long slotted holes at two ends of the S-shaped steel, and polishing the surface of the S-shaped steel to obtain the cloth supporting platform.

When in polishing, the surface is firstly polished to be flat by a polishing machine, and then the surface is polished to be smooth by abrasive paper without burrs.

When the cloth supporting table is used for assembling the cloth supporting device, the cloth supporting device comprises the cloth supporting table, a supporting flat plate fixed on a loom, a first supporting foot and a second supporting foot; one end of the first support leg is fixed on the support flat plate, and the other end of the first support leg penetrates through the round hole through a bolt and is fixedly arranged on the cloth supporting table; one end of the second supporting foot is fixed on the supporting flat plate, the other end of the second supporting foot is fixedly connected with the temple fixing seat, a screw rod is fixed at the bottom of the temple fixing seat, and the screw rod penetrates through the long groove hole and is connected with the nut.

The length of the cloth supporting table is the same as the maximum width of the loom.

The position of the temple fixing seat is adjusted through the position of the sliding screw rod in the long slot hole, so that the temple fixing seat is suitable for the widths of different fabrics.

Specifically, when the fabric width is changed, the nut is loosened, the screw rod slides along the long slotted hole, and after the screw rod is adjusted to a proper position, the nut is screwed to fix the temple fixing seat on the fabric supporting table.

The auxiliary spraying of the loom is arranged in the square hole of the cloth supporting platform.

When the double compression rollers are changed into the single compression roller for coiling the compression roller, the operation process is as follows: the upper pressure roll of the double pressure roll was removed leaving only the pressure roll.

When the double pressure roller is adopted, the fabric directly winds into the cloth roller after sequentially passing through the friction roller, the upper pressure roller and the lower pressure roller.

After the single-press roller is changed, the fabric is directly wound into the cloth roller after sequentially passing through the friction roller and the lower pressure roller.

The single compression roller is changed into the single compression roller, so that the cloth cover extrusion time and distance can be reduced, and slippage and staggered layers can be prevented.

When reducing cloth roller tension, the operation process does: the L value of the cloth roller (shown in figure 5) is adjusted to 70mm from the standard 60mm, and the cloth roller winding tension is adjusted to 15-20N.
