Preparation method of weft plain stitch knitted fabric based on 3D printing

Abstract

The invention discloses a preparation method of a weft plain stitch knitted fabric based on 3D printing. The method comprises the following steps of obtaining control point coordinates of a weft plainstitch knitted fabric structure under space coordinates by adopting a non-uniform rational B spline curve modeling method, obtaining an axis path of a single coil according to the control point coordinates, conducting lofting modeling along the axis path of the single coil by taking the cross section of the yarn as a forming surface to form a three-dimensional model of the single coil, and conducting lofting modeling on the three-dimensional model of the single coil according to the winding direction of the weft plain stitch knitted fabric to form a three-dimensional model of a to-be-formed weft plain stitch knitted fabric structure. Through 3D printing of the weft plain stitch structure, the mutual nesting relation between the coils can be seen through the printing effect, the problem that test weaving is continuously conducted in order to see the designed organization structure, yarn color, density and other effects before an existing knitted fabric is woven on a machine is solved,the fabric production period is shortened, the designed organization effect can be seen in time through 3D printing, materials are saved, the production cost is reduced, and the production efficiencyis improved.

Description

technical field [0001] The invention belongs to the field of 3D printing, and in particular relates to a method for preparing a weft jersey knitted fabric based on 3D printing. Background technique [0002] With the improvement of people's quality of life, the requirements for clothing are getting higher and higher, and personalized clothing is gradually integrated into people's lives and is loved by people. Fashion people have higher requirements for their connotation and artistic taste, and they prefer to use design to show their individuality and distinctive fashion attitude. The clothing design form supported by traditional craftsmanship has made people feel aesthetically tired and cannot meet people's growing clothing design needs. .

Problems solved by technology

Fashion people have higher requirements for their connotation and artistic taste, and they prefer to use design to show their individuality and distinctive fashion attitude. The clothing design form supported by traditional craftsmanship has made people feel aesthetically tired and cannot meet people's growing clothing design needs.

Before the mass production of traditional weft jersey fabrics, in order to see the design structure, yarn color, density and other effects, it is necessary to continuously carry out small sample trial weaving, and the traditional garment production process is cumbersome and the production cycle is long, so it is impossible Achieving the production of a single piece of clothing fabric will result in a large amount of waste of materials and a backlog of product inventory
