However, the silk is fragile, and has the defects of friction resistance, easy fluffing and wrinkling and the like, and the problems of grey injury, dull color, stiff hand feeling and the like of the silk fabric are caused by washing. At present, a dry cleaning method is generally adopted for cleaning high-grade silk fabrics, even if the dry cleaning method is difficult to avoid abrasion and ash damage in the dry cleaning process, the dry cleaning cost is high, and the dry cleaning agent is not environment-friendly and has the risk of carcinogenesis.
The machine-washable grey injury-preventing treated silk or silk-containing fabric can change the problem of delicate silk, so that the silk is wear-resistant, in particular to wear under the wet condition in the machine-washable process, the silk fiber in the fabric is not fibrillated after being washed and dried for 20-50 times in the family, no obvious grey injury is generated, the chemical bonding force of dye and the fabric is improved by the treatment process, the washed fabric is not obviously discolored, and the durable and bright in the luster aspect and the durable and smooth in the hand feeling aspect of the silk or silk-containing fabric are truly realized. Therefore, the machine washable silk or silk-containing fabric and the production process thereof are the problems which are urgently needed to be solved in the current market.
At present, researches on preventing grey injury and stiff hand feeling caused by fibrillation of real silk fabrics are still less, and the treatment of the real silk often influences excellent performances such as smooth and waxy hand feeling, bright luster, moisture absorption and retention of the fabrics.

TABLE 1 Effect of fabrics after machine washing
The machine washing method refers to the 4G method in GB/T8629-2017, the softness is the test data of a fabric style instrument, and the dripping diffusion time test refers to GB/T21655.1
The data in table 1 shows that the silk or silk-containing fabric treated by the cold pad-batch ash damage prevention technology can not be damaged by ash after multiple machine washes, the machine wash resistance is greatly improved, the silk or silk-containing fabric is not discolored after machine washes, meanwhile, the softness performance of the silk or silk-containing fabric is maintained, the phenomenon of hardening is avoided, and the cold pad-batch ash damage prevention technology disclosed by the application does not influence the hydrophilic performance of the silk or silk-containing fabric and can maintain excellent moisture absorption performance through a dripping diffusion time test.
TABLE 2 Effect of anti-greying treated fabrics
| Before treatmentPost color difference | Gram weight before treatment | Gram weight after treatment | |
| Example 2 anti-ash sample | 0.2 | 68 | 67 |
| Comparative example 4 anti-ash sample | 1.5 | 68 | 62 |
The data in Table 2 show that the acidic silk treated by the dye vat has obvious color change, and the dyeing by the jig dyeing machine can lead to flatter tissue style and fiber damage of the silk fabric, so that the gram weight of the fabric finished product is obviously lightened, and the acidic silk double-crepe fabric is more suitable for cold-pad low-temperature treatment.
Finally, what is necessary here is: the above embodiments are only for further detailed description of the technical solutions of the present application, and should not be construed as limiting the scope of the present application, and some insubstantial modifications and adjustments made by those skilled in the art from the above description of the present application are all within the scope of the present application.
