Problems solved by technology

[0005] After sizing and drying, the hardness of the fabric will increase, and the fit between the fabric and the guide belt of the digital printing machine will decrease. The guide belt needs greater viscosity to keep the fabric flat and requires more glue. The cloth wool will be bonded to the guide belt, causing the pollution of the guide belt. Even after the subsequent scraper is cleaned, water stains will still be formed on the guide belt, which will affect the subsequent printing production process.
[0006] The dried fabric is subjected to dry jet printing. During the jet printing process, the jet printing equipment will form a certain negative pressure adsorption on the fabric, and some impurities or cloth hair attached to the upper side of the fabric will stand upright or fixed after being absorbed, which may Blocking the nozzle of the printing will affect the quality stability of the printing

Embodiment 2

[0049] This embodiment discloses an online sizing printing system based on a single-pass digital printing machine. On the basis of Embodiment 1, refer to Figure 1-7 Shown in detail, the cylinder screen sizing device in the printing system specifically includes a sizing cylinder 5 and a scraping structure 51, a certain amount of foaming slurry is accumulated in the sizing cylinder 5, and the fabric is drawn from the underside of the sizing cylinder 5. Bypassing to achieve sizing; the scraping structure 51 is located on the inner side of the sizing cylinder 5, and presses against the inner peripheral lower side of the sizing cylinder 5, and can squeeze the foaming slurry input into the sizing cylinder 5, and the slurry is transparent. The over-sizing cylinder 5 is coated on the fabric to realize sizing; the scraping structure 51 can use a cylindrical extrusion cylinder 13 or a slurry scraper to squeeze and coat the slurry.

[0050] The sizing cylinder 5 is a cylindrical structu...

Abstract

The invention discloses an online sizing and printing system and a process based on a single-pass digital printing machine, and relates to the field of cloth printing. The online sizing and printing system comprises a sizing structure and a printing structure, the sizing structure is used for coating the surface of a fabric with foaming slurry, the output end of the sizing structure is connected with the printing structure, and the printing structure comprises the single-pass digital printing machine. According to the online sizing and printing system, the foaming slurry and the single-pass digital printing machine are combined for use, and ink is supported by the foaming slurry in the jet printing process and can float on the upper layer of the fabric, so that the surface of the jet-printed fabric is brighter; and the steps are simple, and the cost of a plurality of procedures is reduced.

Description

technical field [0001] The invention relates to the technical field of cloth printing, more specifically, it relates to an online sizing printing system based on a single-pass digital printing machine, and also relates to an online sizing printing process. Background technique [0002] The process of using dyes or paints to form patterns on fabrics is fabric printing. Different color patterns can be formed on fabrics through the printing process to meet the requirements of various consumer groups for fabrics. Among various printing technologies, digital printing is a relatively advanced process. It can directly print the desired pattern on the surface of the fabric through digital printing equipment. It has a wide color gamut, clear and delicate images, and reduces the use of chemical reagents and the environment. Pollution, especially the emergence of single-pass machines, has brought new improvements to digital printing technology and injected new impetus into the traditio...
