Problems solved by technology

The production process of the traditional printing process is roughly as follows: unwinding of gray fabric - seam head - preshrinking - pre-setting - reduction - semi-finished product - printing - steaming - washing - finished product setting - finished product inspection - finished product rolling - shipment, using traditional printing The fabric produced by the process has the problem of low color fastness, and it is easy to fade during the washing process, and the color on the fabric is also easy to adhere to the human skin during the wearing process, causing adverse effects on the health of the wearer

Embodiment 1

[0034] A printing process, comprising the steps of:

[0035] (1) Pre-treatment: After the gray cloth enters the factory, it is first unrolled on the unwinder, and then put into the machine cylinder for refining, washing, desizing, neutralization and other steps in sequence, and degreasing will be added during the desizing process Ling and hydrogen peroxide, the addition amount of degreasing spirit and hydrogen peroxide in water is 2kg / t;

[0036] (2) Pre-shrinking: Put the fabric processed in step (1) into the pre-shrinking machine for pre-shrinking. On the one hand, pre-shrinking can make the fabric shrink to the required degree; When the fabric is finalized, its shrinkage rate is easier to control;

[0037] (3) Pre-setting: Put the fabric processed in step (2) into the pre-setting machine for pre-setting. The pre-setting can fix the size and flatness of the fabric, so that the fabric is not easy to be deformed and twisted during the printing process. , so that after the pa...

Embodiment 2

[0045] like figure 1 As shown, a spray machine applied to the printing process includes a casing 1, a transmission roller 2, a water delivery pipe 3, and a spray head 4. The casing 1 is in the shape of a square box, and an inlet A cloth opening 11 and a cloth outlet 12, the cloth inlet 11 and the cloth outlet 12 are located at both ends of the head and tail of the housing 1 respectively; a water collection tank 13 is provided in the housing 1 and at the middle of the bottom wall of the housing 1 , the bottom wall of the housing 1 gradually sags downwards when approaching the sump 13 from both ends, so that the position of the opening of the sump 13 is at the lowest point of the bottom wall of the entire housing 1; There is a drain pipe 14 communicating with the water collection tank 13; there are multiple transmission rollers 2, and the multiple transmission rollers 2 are located between the cloth inlet 11 and the cloth outlet 12 and are rotatably connected in the housing 1, a...

Abstract

The invention discloses a printing process and a spraying machine applied to the process of the printing process. The printing process comprises the following steps: performing pretreatment, pre-shrinking, pre-shaping, performing reduction, printing, ageing, performing water-washing, shaping, and inspecting finished products, wherein the fabric is subjected to expansion treatment after reduction,and the printed fabric is subjected to supercooled river treatment. The printing process has the following advantages and effects: the fabric is subjected to expansion treatment before printing, poresin the fabric fiber structure can be expanded, dye molecules can be permeated into the fiber easily during fabric printing, the subsequent supercooled river treatment enables to the fiber to be shrunk, the binding force between the dye molecules and the fiber is enhanced, and the dye is not liable to remove in the water-washing and wearing processes, so that the aim of reducing the adverse effecton human health by the dye is fulfilled.

Description

technical field [0001] The invention relates to the field of textile printing and dyeing, in particular to a printing process. Background technique [0002] With the advancement of social productivity, people began to pursue the individuation of clothing, especially after the printing process was invented, the patterns on clothing became more and more complex and bright. [0003] However, as health has been paid more and more attention in recent years, people have put forward higher requirements for the performance of fabrics in all aspects. The production process of the traditional printing process is roughly as follows: unwinding of gray fabric - seam head - preshrinking - pre-setting - reduction - semi-finished product - printing - steaming - washing - finished product setting - finished product inspection - finished product rolling - shipment, using traditional printing The fabric produced by the process has the problem of low color fastness, and it is prone to fading i...
