Ultraviolet ray color-changing printing fabric preparation method

Abstract

The invention discloses a method for preparing ultraviolet color-changing printed fabrics. The prescription by weight percentage of fabric printing color paste is: X percent of ultraviolet color-changing dye, 60 percent of natural modified paste material with the lid containing rate of 10 percent, 0.5 percent of glacial acetic acid, 3 percent of urea, and the balance being water, wherein the mixture ratio of X percent of the ultraviolet color-changing dye in percentage by weight is: 0.2 percent of cationic violet 5BLH, 0.4-0.9 percent of cationic yellow X-10GFF, and 0.1-0.2 percent of cationic red X-5GN. A fabric printing process comprises the following procedures of taking a fabric, printing the fabric, steaming the fabric, washing the fabric, drying the fabric and obtaining a finished product. The parameters of a steaming process are as follows: the temperature of heating with superheated steam is 125 DEG C, and the heating time is 30 min. The method overcomes the problems of hand feeling, free formaldehyde, etc. caused by applying adhesive to prepare ultraviolet color-changing printed fabrics in the prior art, has simple-convenient process and low cost, does not change the prior style of fibers, and is excellent in wet fastness and rubbing fastness. Tests show that: the fabric is environmentally friendly and safe, does not contain 23 carcinogenic aromatic amines or heavy metal ions harmful to human body, and is broad in market prospects.
