Waterless printing production process for woven carpet

Abstract

The invention provides a waterless printing production process for a woven carpet. The waterless printing production process comprises the following steps of preparing a white blank carpet; uniformly spraying and wetting the carpet surface of the white blank carpet by adopting a first auxiliary agent solution, adjusting the rotating speed by adopting a frequency converter, and controlling the moisture content of the white blank carpet to be within a specified range through negative pressure vacuum; spraying ink to the surface of the white blank blanket through piezoelectric control of a spray head, and performing ink-jet printing; performing steaming and color fixing on the carpet subjected to ink-jet printing, and spraying a second auxiliary agent solution in the steaming and color fixing process, so that a primary carpet is obtained, wherein the second auxiliary agent solution is an ADP acid-releasing agent solution or an ammonium sulfate solution; and foaming a color fixing agent, pre-coating the surface of the primary carpet with the color fixing agent, enabling the color fixing agent to be in full contact with fibers through a compression roller and then performing drying, so that the carpet product is obtained. By means of the technical scheme, the ink and the fibers are fully colored, basically no residual matter exists, size does not need to be washed with water after steaming and color fixing, and the washing-free technology is achieved, so that sewage discharge is reduced, and the environment-friendly performance of carpet production is improved.

Description

technical field [0001] The invention relates to the technical field of carpet printing technology, in particular to a waterless printing production technology for woven carpets. Background technique [0002] The raw materials for the preparation of carpets are widely used, such as cotton, hemp, wool, silk, grass and other natural fibers or chemical synthetic fiber raw materials, which are processed by manual or mechanical processes, tufted or textile. Carpet is one of the traditional arts and crafts with a long history in the world. It is often used in high-end residences, hotels, stadiums, exhibition halls or vehicles. It has noise reduction, heat insulation, and decorative effects. , heat preservation and other functions. [0003] In the prior art, woven carpet tiles require dyeing and weaving of dyed yarn, which is dyed according to the weight-to-bath ratio of the fabric, which leads to excessive use of water resources and serious pollution. The machine weaves according...
