Description

TECHNICAL FIELD

[0001] The present application relates to the field of high-end home textiles and garment fabrics, and particularly relates to a method for preparing a plush full high-resilience cut-pile cotton fabric. BACKGROUND

[0002] The cut-pile cotton fabric is a fabric prepared by using a double-rapier loom to weave a double-layer structure and then using a machine to cut the pile. The cut-pile cotton fabric has a fine and soft pile, a soft touch, a good skin friendliness and a good compression resilience. The production cost of the cut-pile cotton fabric is very high, and the finished product has a high requirement. The cut-pile cotton fabric has a history of more than 100 years, but now with the development of chemical fibers and cellulose fibers, the cut-pile cotton fabric has exposed many problems. For example, the cotton fiber lacks the resilience and smoothness of chemical fibers, which leads to a short service life in actual use; and the cotton fiber does not have a good drape and fullness as viscose fiber. In recent years, new processing equipment and new process schemes are continuously broken through, and the cut-pile cotton fabric needs to be combined with the new processing equipment and process to improve the product quality.

[0011] (3) Add soft and fluffy treatment: immerse the sample cloth in the working solution for 0.5-1 minute, use a vacuum water pump to remove part of the water, add the sample cloth into a circular drying machine, heat to 60-90℃, and work for 20-40 minutes to perform fluffy treatment.

[0012] (4) Smooth bristle finishing: add 5-20 parts of smooth and bright softener 6631 (purchased from Lian Sheng Chemical Industry), 10-30 parts of non-iron resin FEC (purchased from Jiangsu Ru Yang Antai New Material Science and Technology Co., Ltd.), and 2-6 parts of magnesium chloride to water to 1000 parts to prepare a working solution, immerse the fluffy treated fabric in the working solution for 0.5-1 minute, use a vacuum water pump to remove part of the water, pre-dry at 80-110℃ for 0.5-2 minutes, then pass through 2 reverse needle cloth brushes and 1 forward needle cloth brush to brush the pile to be fluffy and smooth; pass through a setting machine at a temperature of 90-135℃ for 2-4 minutes to dry and cut the pile to obtain the cotton fabric.

[0013] (5) Pile bottom gluing: add 1-2 parts of methacrylic acid to 80-150 parts of polyacrylate solution to stir for 5-15 minutes to obtain polyacrylate glue, and use rolling coating process to coat the polyacrylate glue to the bottom of the cotton fabric and penetrate into the pile root, and then dry to obtain the cut velvet cotton fabric with full pile and high resilience.

[0014] In an embodiment of the present application, in step (1), the cut velvet cotton fabric is made by using a double sword bar weaving machine, the ground warp and weft yarns are made of 32S / 2D tight-spun cotton, and the pile warp is made of 32S / 2D combed cotton, and the pile surface is flat and delicate through the cutting process.

[0015] In an embodiment of the present application, in step (2), the cotton fabric is treated with caustic soda and refiner by using a flat complex long car, which can remove the wax and cotton seed shell impurities on the surface of the cotton fiber, and make the fabric have better capillary effect, which is convenient for fluffy and soft finishing in the later process; the roller treatment can fully immerse the working solution into the fiber; the drying cylinder temperature is 80-120℃, and the drying time is 2-5 minutes, which can dry the pressed pile, and is beneficial to bulk packing.
