Abstract

The invention relates to a preparation method of a silk printed fabric. The preparation method comprises the following steps of applying a macromolecular modifier to the surface of paper, and treatingat the temperature of 60 DEG C, so as to obtain the transfer printing paper, wherein the weight increasing amount of the paper is 10 to 20g / m<2>, and the macromolecular modifier is prepared from thefollowing components in percentage by mass: 0.5 to 5% of water-soluble hot melt glue, 2 to 12% of thickener, 0.5 to 3% of acid and alkaline agent, 2 to 8% of moisture absorber, and the balance of water; performing ink jetting and printing onto the transfer printing paper by active dye ink or acid dye ink, and drying, so as to obtain the transfer printing paper jetted with ink; soaking and rollingthe silk fabric, wherein the liquid entrapping rate of the fabric is 80 to 90%; laminating the transfer printing paper jetted with ink and the pretreated silk fabric in a hot press way, steaming by vapor, and washing by water, so as to obtain the silk printed fabric, wherein the permeation hot press temperature is 100 to 160 DEG C, and the hot press pressure is 3 to 6MPa. The preparation method has the advantages that the technology is simple and environmentally friendly; the color depth value of the prepared silk printed fabric is 4 to 7, the permeation rate of dye is 90% to 111%, and the color fixation rate is 79 to 90%.

Description

technical field [0001] The invention relates to the technical field of textile printing, in particular to a silk printing fabric and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, more and more people are beginning to pursue returning to natural clothing fabrics. At the same time, people's demand for personalized and multi-variety textiles is increasing day by day. Therefore, when fabrics are dyed and printed, it is very important to maintain the original properties of the fabrics. Known as the "Queen of Fibers", silk fabrics are soft and smooth, soft and light to the touch, and cool and comfortable to wear. [0003] At present, silk printing methods mainly include ink-jet direct-jet printing and traditional rotary screen printing. These two methods have good penetration effect and small color difference between positive and negative. The sewage of dyestuffs and paste auxiliaries causes environmental pollutio...
