Technical Field

The invention relates to a production process of a flat crease-free cold pad-batch dyed skin-care wide tencel fabric, in particular to a dyeing and finishing production technology of a flat crease-free full-straight-roller mercerizing machine half-mercerizing, front-back chromatic aberration not less than 4 grade, left-middle-right chromatic aberration not less than 4-5 grade cold pad-batch dyeing, formaldehyde-free shrink prevention and hyaluronic acid finishing agent one-bath finishing of a wide tencel woven fabric.

Background

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 and is dozens of meters in length often has crease due to the adjustment of the rolling tension, and crease color patterns can be formed after color fixation. Because the fixing process is an exothermic reaction, multilayer water spots are easily formed on the fabric of which the outermost ring of the cloth roll is contacted with the plastic film. 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 21SAnd 6, the sewing thread is thick, the circular seam type seam head is large, and joint marks are easy to generate. The tension force during rolling is generally larger, meanwhile, the warp direction in the color fixing and stacking process is slowly contracted, the extrusion to the seam head is larger, the seam head is easy to generate the seam print, in a serious case, a seam head generates several circles of seam prints, and the fabric with the obvious seam print can only be treated as an off-grade product.

The tencel fabric is easy to generate defects such as dead crease, scratch, white spots and the like in dyeing and finishing processing. The production method of the tencel cotton-linen blended wide-width dyed woven fabric (CN107904923A) is characterized in that when semi-mercerizing 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, and when the woven fabric leaves the straight-roll area and enters the plain washer, as the vertical and back parallelism of a cloth guide roll has certain deviation, the weft direction shrinks, and the cloth cover generates mercerized wrinkles which are difficult to remove and defects of large weft direction shrinkage rate of the woven fabric. The production method of the tencel type wide woven fabric with high pilling resistance (CN109750530A) does not carry out semi-mercerization, and irregular dead folds, scratches and other defects are randomly generated on the cloth surface in the cold pad-batch dyeing process.

Example 2

The width of the woven fabric of wide tencel (A100 type) is 106 inches, and the yarn count is 50s×50sA density of 170X 90 roots/inch;

a cold pad-batch dyeing process for a flat crease-free wide tencel woven fabric comprises the following main production process flows: seam turning → one positive and one negative singeing → rolled amylase stacking desizing → washing → drying → half mercerizing → cold pad-batch dyeing → non-formaldehyde shrink-proof and hyaluronic acid finishing agent one-bath finishing → mechanical preshrinking → inspection and packaging;

when turning over the seam, a circular seam type sewing machine is used, and the thread for sewing the head is 30sAnd 6, the stitch density is 28-32 needles/10 cm, the vertical seams on the two sides of the selvedge are 4-5 cm, and the tail is 3-5 cm.

Half mercerizing is carried out on a 98-pair full-straight-roller mercerizing machine, and the main process flow is as follows: cloth feeding → caustic soda bath in the concentrated caustic soda tank area → heavy padder No. 1 → dealkalization in the first dealkalization tank area → heavy padder No. 2 → dealkalization in the second dealkalization tank area → heavy padder No. 3 → drying → cropping.

The concentrated alkali tank area of the full straight roller mercerizing machine is provided with 40 pairs of straight rollers, 1 pair of straight rollers consists of an upper rubber roller and a lower metal straight roller, wherein the No. 2 and No. 4 rubber straight rollers are spreading rollers, and the concentration of caustic soda in the concentrated alkali tank area is 80-90 g/L;

after the concentrated alkali solution is discharged from the concentrated alkali tank area, the concentrated alkali solution is subjected to expanding by an expanding roller, enters a No. 1 heavy padder for mangling (the liquid carrying rate is 55 percent), and then enters a first alkali removal tank area with 20 pairs of straight rollers, wherein No. 50, No. 52 and No. 54 rubber straight rollers are expanding rollers; after leaving the first dealkalization groove area, the rubber is subjected to width expansion by a width expansion roller, enters a No. 2 heavy padder for mangling (the liquid carrying rate is 55 percent), and enters a second dealkalization groove area with 38 pairs of straight rollers, wherein No. 64 and No. 67 rubber straight rollers are width expansion rollers. The first and second dealkalizing tank regions are respectively provided with 5 and 10 groups of spray pumps, wherein the first dealkalizing region is provided with 5 groups of spray pumps which are respectively connected with 4 spray pipes. The temperature of the spray liquid in the first dealkalizing tank area is 70-75 ℃. The second dealkalization district has 9 groups of spray pump and each links 4 shower respectively, and 1 group of spray pump links 2 shower finally, and the second dealkalization groove district spray liquid temperature is 50 ~ 55 ℃. Clean water is sprayed to the straight-roller spray pipes corresponding to 98 th and 97 th spray pipes, and light alkali liquor is sprayed to the other spray pipes. And (3) leading the light alkali liquor to flow back to the first dealkalizing tank zone from the second dealkalizing tank zone, leading the concentration of the light alkali sprayed by the straight roller spray pipes corresponding to 42 th and 41 th straight roller spray pipes to reach 40-45 g/L, and recycling for later use. And after the cloth is discharged from the second dealkalization area, the cloth is rolled by a No. 3 heavy padder (the liquid carrying rate is 55 percent) and enters two rows of 20 drying cylinders for drying, wherein the two drying cylinders at the bottom of the second row are cooling cylinders for reducing the temperature of the cloth cover. The pH value of the cropping is 7-8, and the moisture content is 3% -4%.
