Study On The Basic Texture Of Three-dimensional Printing Clothing

The traditional clothing in the manufacturing need to go through spinning,weaving,dyeing,cutting,sewing and other processes.However,3D printing technology used in clothing field eliminates many processes of traditional crafts and can achieve personalized production and rapid manufacturing.The textures of 3D printing clothing have significant impacts on the performance of printed clothing.However,the current study on the textures of 3D printing clothing is almost blank.In this paper,the basic clothing textures printed by 3D printer are studied and the textures suitable for 3D printing clothing are developed,which promotes the development of 3D printing clothing.The cross-sectional morphology and the molecular structure of the flexible printed-material PLA before and after melt-spinning,thermal properties,tensile properties and resilience of the filaments after spinning were analyzed.The results show that the filaments are smooth in longitudinal cross-sections and without interruption.The results show that the material has good spinning effect.The internal molecular structure of the flexible PLA material does not change before and after the high-temperature melt-spinning and the main absorption peak of the PLA material after melting at high temperature is weak.The glass transition temperature of the flexible PLA is 65? and the melting point is 165.57?.The breaking strength of the filament is 461.9cN and the elongation at break is 691.67%.The elastic recovery rate of the fixed elasticity of the filament is 68.37%and the elastic recovery rate of the fixed load is 68.69%,which shows that the flexible PLA has good elasticity and crease resistance.Based on the 3ds Max software,the Peirce circular model and the NURBS curve modeling method were used to determine the yarn axis path of the woven fabric and the knitted fabric according to the coordinates of the control point.Through the operation of lofting and duplication,three-dimensional model of woven plain weave,1/3/right twill weave and knitted fabric stitch,rib 1×1 stitch were obtained.Based on the textures modeling of knitted fabric and woven fabric,three kinds of mesh textures model of imitated plain weave,rhombus texture,imitated fabric stitch were established.Using the "Tianwei" Colido X3045 quasi-industrial-grade 3D printer,the printing effects under different printing parameters were compared and analyzed.The optimum printing parameters were as follows:nozzle temperature 205?,printing room temperature 23?,layer thickness 0.2mm,filling speed 80mm/s,extrusion speed 130mm/s.The three-dimensional texture models of knitted fabric,woven fabric and mesh textures were printed under the best printing parameters.The printing results shows that the texture models of the 3D printed woven fabric and knitted fabric can be seen the state of the yarns and can show yarn bending and coil nesting effect.Three kinds of developed fabric textures have flat surface.The printing fabric textures are soft and suitable for three-dimensional printing clothing.The basic mechanical properties of three kinds of printed mesh fabric textures were tested and analyzed finally.The results show that the tensile fracture properties,the tearing performance,the bursting performance are related to the edge width of the printed meshes,the thickness of printed fabrics and the printing textures.When the thickness of the printed fabric is constant and the edge width of the printed meshes is the same,the mechanical properties of the different printed fabric textures are different.When the thickness of the printed fabric is constant,for the same printed mesh texture,with the edge width of the mesh increases,the breaking strength,breaking elongation length,tear strength and bursting strength also increases.58 Figures,10 Tables,123 References.
