Problems solved by technology

However, this method needs to use a professional coating machine to coat the carrier, which greatly increases the equipment investment and printing cost, and often causes inconsistent winding tension during coating and winding, which affects printing. The accuracy of plate registration; and the method of adding hot-melt substances to the printing paste to directly print the carrier, because there is too little ink in the shallow layer of gravure printing, so it is not suitable for gravure printing that can print photo effects, only suitable for printing rough screen printing

Abstract

The invention discloses a preprocessing size for textile printing. The preprocessing size comprises the following compositions in percentage by weight: 5-50% of a hot melting material, 0.5-15% of a printing gum, 0.5-6% of an acid-releasing agent or an alkali-releasing agent, 0-20% of a water-absorbent, and the balance of water. The invention also discloses a preparation method and applications of the preprocessing size for textile printing. According to the invention, a conventional wet transfer film or wet transfer paper is used for hot-melting transfer printing, so that the hot-melting transfer printing is implemented without specially coating a hot-melting carrier, and hot-melting printing ink does not need to be specially configured, thereby greatly reducing the cost of hot-melting transfer printing. The preprocessing size for textile printing and the preparation method and applications of the preprocessing size disclosed by the invention are applied to the hot-melting transfer printing of textiles, the process is simple, the quality is easily controlled, and the graded product rate of hot-melting transfer printing is greatly improved; and according to the invention, the hot-melting transfer printing is implemented without using an expensive coating machine and just through using common wet transfer equipment, thereby facilitating the popularization of an environmental-friendly process of hot-melting transfer printing.

Description

technical field [0001] The invention belongs to the field of textile printing and dyeing, and in particular relates to a textile printing pretreatment slurry with hot-melt performance and a preparation method and application thereof. Background technique [0002] Textile transfer printing has the advantages of rapid market response, especially suitable for small batches, multiple varieties, realistic patterns, and the ability to print various photo-style patterns, small investment, less labor, energy saving and emission reduction, and many other advantages. Therefore, the transfer printing process has always been favored by the market. [0003] However, the most mature existing transfer printing technology is the sublimation transfer printing of disperse dyes, but it is only suitable for the printing of polyester fabrics. Fiber fabrics are not suitable. [0004] In order to solve the transfer printing of natural fibers and acrylic and nylon fabrics, wet transfer printing h...
