Detailed Description
The invention provides a washing method of jean fabric and the jean fabric, and the invention is further described in detail below in order to make the purpose, technical scheme and effect of the invention clearer and more clear. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The water washing method of the jean fabric provided by the invention comprises the following steps:
a. desizing the jean fabric;
b. performing enzyme washing on the jean fabric at least once;
c. carrying out first water washing on the jean fabric;
d. carrying out secondary water washing on the jean fabric; adding a friction color fastness improving agent in the second washing process.
The reason for improving the color fastness to rubbing by adopting the washing method of the denim fabric provided by the invention mainly comprises two reasons: 1. washing off the loose color on the surface of the fabric, and 2, adding a rubbing color fastness improver; the crocking fastness can be improved by these two methods. The coloring principle of the indigo dye is that the indigo dye is firmly combined with fibers on the yarns in a hydrogen bond mode after being reduced into a leuco body, but the number of the fibers capable of being combined with the indigo dye into the hydrogen bond is limited, so that most of the indigo dye still adheres to the yarns, and the denim fabric is easy to fade. The reason why the rubbing color fastness improver is added is that the substance can be combined with the fiber in a hydrogen bond mode, then the rubbing color fastness improver is a cation, has positive charges, can react with dye with anions, and finally can form a film on the fabric, so that the dye can be wrapped, the dye can be prevented from falling off, and the color fastness of the fabric can be improved. And the removal of the flooding on the surface of the fabric is to remove the indigo dye which does not form firm hydrogen bonds with fibers, so that all the dyes which are not firm on the surface of the fabric are removed, and the rubbing color fastness is further improved.
In the scheme, firstly, the fabric is desized, because the fabric surface has a layer of sizing agent, the hand feeling is rigid, and meanwhile, impurities exist, the fabric is desized by adding the alkaline oil, the sizing agent on the surface of the fabric is removed, the hand feeling is good, in the process, the dye on the surface of the yarn can fall off the yarn in the soaking process and the machine washing operation, the dye is added in order to prevent the fabric from being stained again, particularly the reverse side of the fabric, if the reverse side of the fabric is seriously dyed, yellowing can occur after a period of time, the quality of the fabric is influenced.
In the scheme of the invention, the step b needs to be performed at least once by enzyme washing, and if the enzyme washing is performed only once, the rubbing color fastness can be improved, but the optimal effect is not achieved.
