Problems solved by technology

As for the textile and garment industry, although the characteristic of 3D printing being personalized is in line with the trend of personalization in this industry, there are some attempts in the industry, but limited by the limitations of 3D printing materials, it has not been able to truly realize the application so far.
[0003] In the process of 3D printing, stereolithography requires materials to be photosensitive; laminated solid manufacturing and 3D printing adhesives require the use of adhesives to bond the coating layer or material powder, which affects the feel and wearability; selective laser sintering, selection Permanent laser melting requires materials to be resistant to high temperatures; the requirements of these processes for materials are beyond the reach of general textile materials
Moreover, textile materials are generally soft and difficult to accumulate and form, so they cannot be directly used as 3D printing materials.
In general, there are still many problems in the application of 3D printing in the textile and garment industry, and a better solution has not yet been found.

Abstract

The invention relates to a preparation method of a 3D printing material, and the preparation method comprises the steps of: adding 17-40 parts of cellulose to 60 to 83 parts of a solvent, swelling ata temperature of 80 to 120 DEG C, and shearing to obtain a cellulose solution; obtaining soft nylon, melting the soft nylon at melting temperature of 130 to 180 DEG C; mixing the cellulose solution with the melted soft nylon at mixing temperature of 130 to 180 DEG C to obtain the printing material. The preparation method of the 3D printing material solves the technical problem that a textile material directly used as a printing material is difficult to stack and form due to the softness of the textile material.

Description

technical field [0001] The invention relates to the field of textile technology, in particular to 3D printing materials and their preparation methods and applications. Background technique [0002] 3D printing has always been a hot spot in technology in recent years. With a lot of research, its technology itself has made great progress, and has been used in aerospace, automobiles, industrial design, models, parts production, film and television, medical, footwear, etc. The industry has started large-scale application. Compared with traditional manufacturing technology, 3D printing itself has the characteristics of high precision and short production cycle, and is more suitable for the production of personalized and complex structure products. As for the textile and garment industry, although the characteristic of 3D printing's preference for personalization is consistent with the personalization trend of this industry, there are some attempts in the industry, but limited by...
