Technical Field

The invention relates to a dyeing and finishing process of an alkali-free cold pad-batch dyed antibacterial skin care fabric, in particular to a dyeing and finishing process technology of an antibacterial skin care fabric, which is prepared by mercerizing a smooth crease-free full-straight-roller mercerizing machine of a cation modified cotton and cotton blended wide woven fabric, carrying out alkali-free cold pad-batch dyeing with the front-back chromatic aberration not less than 4 and carrying out alkali-free cold pad-batch dyeing with the left-middle-right chromatic aberration not less than 4-5, and carrying out one-bath finishing with a formaldehyde-free shrink-proof and hyaluronic acid finishing agent.

Background

When cation modified cotton and cotton blended wide woven fabric is mercerized on a straight-roll mercerizing machine consisting of a conventional straight-roll alkali soaking area, a straight-roll alkali removing area, a open washing machine and the like, the width of mercerized cropping cloth is smaller than the lower limit of the product width due to insufficient width expansion of the weft width of the fabric, and the water shrinkage rate of the weft width of the fabric is large. And the mercerization is performed with one-time pre-stentering, so that the production cost is increased. When the fabric leaves the straight roll area and enters the open washing machine, the cloth cover is easy to generate mercerized dead wrinkles which are difficult to remove due to certain deviation of the up-down and front-back parallelism of the cloth guide roll and the difference of the left, middle and right tension of the fabric. The open washing machine has large water tank volume, large water washing counter-flow water quantity, slow heat exchange, high water temperature, difficult cleaning of fabrics, mercerized cropping pH of more than 8, and large energy consumption and water consumption.

When the cation modified cotton and the cotton blended wide woven fabric are dyed in a jig dyeing machine, the dye is easily adsorbed on the fabric due to the large acting force between the cation group on the cation modified cotton and the anion group of the reactive dye, and the dye has poor migration property due to the large acting force of ionic bonds, so that unstable color light and head-tail color difference are easily generated. In the existing cold pad-batch dyeing, cloth guiding and wrapping at two ends of a fabric are respectively about 20 to 10 meters of polyester cotton cloth, and the innermost dozens of meters of the fabric of one cloth roll can have transition colors of dozens of meters because the dye concentration of a dye tank is not reached to an equilibrium point when the fabric is started initially. Meanwhile, the fabric which is originally rolled for dozens of meters often has crease marks due to the adjustment of the rolling tension, and the head of the fabric has crease marks. The fabric with the outermost circle of the cloth roll contacting the plastic film is easy to form multi-layer water spots. The fabric has color difference between the head and the tail and the middle after cold pad-batch dyeing. The head and tail fabrics with the color difference less than 4 levels can only be treated as off-grade products.

The current fabric circular seam type sewing thread is 21^SAnd 6, the sewing thread is thick, the circular seam type seam head is large, and joint marks are easy to generate. The tension during rolling is generally larger, meanwhile, the warp direction has a slow shrinkage in the cold pad-batch dyeing stacking process, the extrusion to the seam head is also larger, the seam head is easy to generate joint marks, in severe cases, a seam head generates several circles of joint marks, and the fabric with obvious joint marks can only be treated as an off-grade product.

A high-count high-density high-quality pure cotton wide-width dyed woven fabric and a production method thereof (CN107904924A) are characterized in that when half mercerization is carried out on a straight-roll mercerizing machine consisting of a conventional straight-roll alkali-soaking area, a straight-roll alkali-removing area, a plain washer and the like, when the fabric leaves the straight-roll area and enters the plain washer, the weft shrinkage is caused, and the cloth cover generates mercerized wrinkles which are difficult to remove and defects of large weft shrinkage rate of the fabric. A production method of pure cotton bright red extremely wide woven fabric with high wet friction resistance (CN107326595A) adopts polyester cotton cloth with two ends and wrapping cloth of about 20 to 10 meters respectively, and the fabric has defects of color difference between the head and the tail and the middle after cold pad-batch dyeing.
