Embodiment 1

[0019] A fine printing process is characterized in that it comprises the steps of:

[0020] 1) Pretreatment of printed paper: add coating to the base paper of printed paper, carry out modification treatment, and dry for later use;

[0021] 2) Preparing printed patterns: printing the printed paper obtained in step 1) with disperse dyes;

[0022] 3) Transfer printing: stick the printed side of the printed paper obtained in step 2) to the fabric, turn on the pressing machine, adjust to a moderate pressure, keep it unchanged, set the temperature and time of the pressing machine, and wait until the temperature After reaching, transfer printing is carried out to obtain transfer printing fabric. The pressing temperature is 220°C, and the pressing time is 60s;

[0023] 4) Shaping: drying and shaping the printed fabric obtained in step 3), and then washing and drying.

[0024] Specifically, the coating in step 1) is composed of a waterproofing agent, an adhesive and a hydrophilic ag...

Abstract

The invention provides a fine printing process, particularly relates to the technical field of transfer printing. The process comprises a pretreatment of a calico paper, preparation of printing patterns, transferring printing and sizing. During pretreatment of the calico paper, the body paper of the calico paper is provided with a coating, modifying and drying are performed for standby application; during preparation of the printing patterns, the calico paper subjected to preteatment is processed by printing; during transferring printing, one surface of the calico paper with patterns obtainedfrom the preparation of the printing patterns is adhered to a fabric, a press is started to be adjusted to proper pressure for some time, the temperature and the time are set, the transferring printing is performed after the temperature reaching the set temperature to obtain transfer printing fabric; during sizing, the obtained printing fabric is dried, shaped, washed and dried. According to the fine printing process, the calico paper is modified, so that the transferring printing of the fabric such as natural fiber and cotton with proper hydrophility is obtained.

Description

technical field [0001] The invention belongs to the technical field of transfer printing, and in particular relates to a fine printing process. Background technique [0002] Transfer printing is a printing method that first prints dyes on paper, and then transfers the dyes on the transfer paper, that is, the printing paper, to the fabric under certain conditions. The method of using heat to sublimate the dye on the transfer paper and transfer it to the dyed synthetic fiber is called the thermal transfer method. The printing method that uses a certain temperature, pressure and solvent to peel the dye from the transfer paper and transfer it to the printed fabric is called the wet transfer method. [0003] However, the current transfer printing is mainly suitable for chemical fibers, not for the printing of natural fibers, cotton and other fabrics. In order to be suitable for the printing process of more fabrics, it is necessary to modify the printing paper. [0004] Therefor...
