Problems solved by technology

Although traditional electric embroidery can add some bright colors to bamboo products, it is abandoned by most home textile enterprises due to the existence of unsafe factors such as embroidery on the surface of bamboo products and potential breakage.
Although the laser imprinting technology has improved its safety in recent years, its color is monotonous, and it cannot express the demands for colorful life pictures. It was also abandoned
In the past, the method of printing patterns directly on the bamboo surface caused the printing fastness to be unsatisfactory due to the unstable factors of bamboo.

Abstract

The high temperature flat pressing printing process for bamboo product includes the following steps: 1. polishing the bamboo product; 2. printing the pattern on paper; 3. cleaning the bamboo product and electrostatically spraying UV or PU paint; 4. covering the printed paper onto the surface of the painted bamboo product; 5. transferring the pattern from the paper to the surface of the bamboo product inside a high temperature flat pressing equipment at controlled temperature, pressure and time; and 6. spraying UV or PU paint to the bamboo product and twice color fixing treatment. Compared with traditional technology, the present invention has one increased surface curing treatment step, and thus homogeneous flat pressing force at high temperature and high quality of the printed pattern.

Description

technical field [0001] The invention relates to a printing process on bamboo products, especially on bamboo bed mats and other bamboo products, more specifically, a high-temperature flat-press printing process on bamboo bed mats and other bamboo products. craft. Background technique [0002] Bamboo is widely distributed and planted in my country and Asia. Because of its short growth cycle and high utilization rate, it has become an economical plant widely recommended for planting. Bamboo has the function of purifying the air, and its derivatives and residues are basically non-polluting. It has been planted and applied more widely in today's environment-friendly environment. Bamboo and bamboo products are also widely used in household, home furnishing and home decoration from traditional farm implements and agricultural machinery in real life. Although traditional electric embroidery can add some bright colors to bamboo products, it is abandoned by most home textile enterpr...
