Description
Technical Field
The invention relates to the technical field of fabrics, in particular to a brocade and wool interwoven four-side elastic fabric and a dyeing and finishing processing process thereof.
Background
With the continuous improvement of the living standard of people, the requirements of people on the performance of clothes are continuously improved. The properties of the fabric from which the garment is made will largely determine the quality of the garment. Considering the factors of comfortable clothes, free movement, beautiful human body curve and the like, the fabric with good elasticity is needed for making the fabric of the clothes, the existing elastic fabric is mostly knitted or woven, but the elastic effect is not good, and particularly after long-term use, the original elasticity can be lost, so that the clothes are inconvenient for people to wear. Moreover, the following problems exist in the dyeing and finishing process of the existing elastic fabric:
1. the method for preparing the cloth has the advantages that the fabric falls into the cloth vehicle directly after being uncoiled by the cloth preparing uncoiler and flows into the next procedure operation through the cloth vehicle, and the defect that the fabric is loose and naturally contracted after falling into the cloth vehicle, and does not have a flat surface for supporting, and the contraction difference of the front surface and the back surface of the fabric easily causes the phenomenon of edge curling, thereby causing great trouble to the operation of the next procedure.
2. The oil removing problem in the pretreatment adopts a continuous desizing and oil removing mode of a long tightening desizing machine, and the defect that the fabric is easy to be adhered to alkali to damage wool fibers is overcome. Because the compact continuous desizing machine is public, most products are alkaline desizing and deoiling through the equipment, wool fibers are not alkaline-resistant, and the fibers are easy to damage after being stained with alkali.
3. The problem of dyeing reproducibility is solved, and the existing dyeing process adopts the following steps: adding an auxiliary agent at 38 ℃ for 5min, adding a dye for 20min, circulating for 5min, heating at 1.0 ℃/min to 100 degrees by 30min, cooling at 2 ℃/min to 80 ℃, and shearing and carrying out color matching. The disadvantages of this method are that some front nylon fiber is colored more and the color is darker, some back wool fiber is colored more and the back color is darker. Tests show that (as shown in the figure) wool is colored at the temperature below 30 ℃, the coloring is relatively quick, nylon begins to be colored at the temperature of about 40 ℃, the coloring is much slower than that of wool fibers, more than 85% of dye in dye liquor is dyed on the fibers after the dyeing is carried out at the temperature of 80 ℃, and the front side (nylon side) is mainly used for color matching. The conventional dyeing process has the defects of low color reproducibility, much more addition, low efficiency and frequent uneven dyeing.
4. The water splashing effect and the hand whitening problem are solved by adopting a single fluoride-free super-splashing waterproof agent for shaping and finishing, and the defects of the method are that the using amount is as large as 80G/L, the water splashing effect is not ideal, the target requirement is ISO4920-2012 standard level 4-5, generally only level 3 can be achieved, and the phenomenon of hand whitening (namely, the phenomenon of white scratches left on the surface of a fabric after the fabric is visually grasped by a hand) can also occur.

The open-width intermittent oil removal mode of the jig dyeing cylinder is adopted, because the cylinder body of the jig dyeing cylinder is relatively small, about 2000L, the cleaning is convenient, and the cleaning is cleaner, and the auxiliary agent formula is as follows: soda ash is 0.5g/L, the emulsification degreasing agent 1132 is 1g/L, the refined liquid is 400L, and the temperature rising formula adopts a gradual slow temperature rising process: 2 paths of cold water feeding-operation, 40 ℃ 1 path, 50 ℃ 1 path, 60 ℃ 1 path, 70 ℃ 1 path, 80 ℃ 1 path, 90 ℃ 1 path, 100 ℃ 1 path, 105 ℃ 6 path, hot washing 2 paths, cold water washing drainage washing 1 path, then discharging the cloth, wherein the breadth of the blank cloth is about 205CM, and the breadth is reduced to about 148CM after the blank cloth is subjected to open-width thermal shrinkage oil removal through a dye jigger. Therefore, the fabric is open and shrinks under the support of the roller, and the problem of edge curling generated in the shrinking process is effectively solved; in addition, because the cylinder body is small, the PH value of the refining liquid is easy to control, and the phenomenon that wool fibers are damaged or refining oil removal is not in place due to improper PH value control is avoided.

Although the dyeing process time is prolonged from the original 140min to 155min and is prolonged by 15 min, the once success rate of dyeing is improved, so the total efficiency is improved, and the faults of uneven dyeing and color shading are reduced.
Spraying and washing process before drying: as shown in fig. 6, the mixture is dried after being sprayed and cleaned by hot water at 60 ℃; the auxiliary ingredients possibly remaining on the fabric are effectively cleaned, the dyeing auxiliary agents remaining on the fabric have negative influence on the post-water-pouring effect, and the hot water used by people is the return water for dyeing and cooling, so that the water resource can be reused.
A shaping procedure: the invention is shown in Table 2 after the comparative tests of multiple sets of setting formulas
Table 2 is a table of parameters of a plurality of sets of setting formulas
Wherein, FA246 is fluorine-free super water repellent, FA247 is three-proofing finishing synergist, and FA901 is penetrant.
Comprehensively considering, the fluorine super-splashing waterproof agent, the three-proofing finishing synergist and the penetrant have the best proportioning effect by adopting a No. 6 process 50:3:2, the dosage of the auxiliary agent is low, the water splashing effect is good, and the cloth surface has no hand whitening problem; and after the measures of the spraying and washing process before shaping are combined, the water splashing effect of the fabric can reach 4-5 levels, the fabric surface quality is good, the phenomenon of white hand grasping is avoided, the using amount of the auxiliary agent is low, and the cost is reduced.
