Embodiment 1

[0024] (1) Preparation of anionic nanoporous alumina dispersion: Dissolve 10% sodium polyacrylate and 1% polydimethylsiloxane into deionized water, add 30% nanoporous alumina and mix evenly, carry out with a sand mill Grinding and dispersing to prepare nanoporous alumina with an average particle size of <200nm.

[0025] (2) Preparation of pretreatment liquid: 2% anionic nanoporous alumina dispersion, 1% sodium alginate, 12% glycerol, 1% sodium carbonate, 1% ethanolamide, 0.5% 5-chloro-2-methyl -1-isothiazolin-3-one, the rest is water.

[0026] (3) Padding and drying treatment: immerse the fabric in the pretreatment solution for 5 minutes to ensure that the fabric is fully soaked, then perform one dipping and one rolling treatment, the excess rate is kept at 70%, and then dry at 60°C after padding Dry processing.

[0027] (4) Inkjet printing: use reactive dye ink to print the pretreated silk.

[0028] (5) Steaming for color fixation: place the printed fabric in a preheated s...

Abstract

The invention discloses a method for improving the permeability and clarity of double-faced penetrated print of a real silk fabric and belongs to the field of fine chemical engineering. For solving the problem that the double-faced penetrated print of the real silk fabric has poor permeability and low clarity, the method for improving the permeability and clarity of the double-faced penetrated print of the real silk fabric through the combined effect of negative ion dispersed nano-porous oxide and a penetrating agent is provided, and the permeability, clarity, color depth and brilliance of the double-faced penetrated print of the real silk fabric can be obviously improved. The method is simple in process and can meet the requirements for large-scale production and processing, and luster and strength damage of the preprocessed real silk fabric is small.

Description

technical field [0001] The invention relates to a method for improving the permeability and clarity of double-sided penetrating printing of real silk fabrics, belonging to the field of fine chemicals. Background technique [0002] Penetration printing refers to the treatment of fabrics, so that the printing pattern on the front side of the fabric penetrates to the back side during printing, and finally the front and back sides of the fabric can obtain a printing effect that is not much different. Among the silk printing fabrics, penetration printing is unique, and it is widely used in the printing of silk scarves and handicrafts. The use of inkjet printing technology for silk penetration printing has become an emerging fashion trend. [0003] When inkjet printing is used to perform double-sided permeation printing on silk fabrics, the problems of low permeability and low clarity are prone to occur. If the diffusion of ink in the fabric is considered to be carried out on two...
