Research And Development Of Fully Formed Double-layer Knitted Products

Fully formed knitting technology refers to the technology of one-time forming of products by three-dimensional knitting on a fully formed computerized flat knitting machine.The products woven by fully formed knitting technology are presented as a whole when they are off the machine,which reduces a series of subsequent processes such as fabric cutting and stitching.Domestic research on full forming technology focuses on the knitting principle,basic sweater,conventional tubular structure products and other fields.With full forming becoming a research hotspot in the knitting field,the research on fully formed technology and the diversity of fully formed clothing styles is gradually deepened.The development of fully formed double-layer structure clothing products can not only enrich the styles of fully formed clothing products,at the same time,as the development of special-shaped structure products,it is very necessary to study the core technology of its structural joints.The structure forming mode,pattern design method,weaving difficulty technology and digital display of fully formed double-layer structure are studied.The process model of upper and lower assembly of double-layer structure is studied and realized to complete the seamless connection between digital technology and process production.Firstly,this subject analyzes the design characteristics of fully formed double-layer structure clothing,summarizes the overall and local characteristics of double-layer structure clothing design,studies the forming principles of fully formed double-layer overall and local structure respectively,and analyzes the process forming characteristics and process forming principles of fully formed double-layer connection.The possibility of product design and realization of fully formed double-layer structure is put forward.Secondly,this paper studies the process model establishment and weaving realization of fully formed double-layer structure knitted upper garment.Taking the two-piece blouse sling style as an example,this paper studies the formation of the upper pattern of the double-layer structure,the process conversion and size correction method from the upper pattern to the knitting process pattern,obtains the fully formed process accurate pattern by using the color block slip and color block broken line correction method,and deeply studies the forming methods of the lower hem,body shape,sleeve body connection,neckline,double-layer connection and other parts of the blouse sling,The garment forming process model is established,and the single-layer process forming,double-layer process forming and joint process forming are studied;Through the operation of four needle bed computerized flat knitting machine,the setting of knitting process parameters and the example of Knitted Blouse sling,the fully formed double-layer structure upper model is verified.Thirdly,this paper studies the establishment of fully formed double-layer structure lower garment process model and weaving realization.Taking the style of fake two-piece skirt and trousers as an example,this paper studies the formation of lower garment pattern with double-layer structure,the process conversion method from lower garment pattern to knitting process pattern,deeply studies the forming methods of skirt and trousers leg,crotch,double-layer joint and skirt body,and establishes the lower garment forming process model;Through the operation of four needle bed computerized flat knitting machine and the setting of knitting process parameters,an example of knitting two-piece skirt pants is given to verify the fully formed double-layer structure lower model.Finally,based on the digital design of full-shape knitted clothing,this paper establishes the parametric design and spring particle model method of double-layer structure knitted clothing,realizes the component modeling and adaptive integration of double-layer structure clothing,carries out the texture design of knitted fabric based on yarn,and completes the 3D garment mapping texture design through pattern mapping and pattern alignment.Through the research and development of fully formed double-layer structure garment products,this topic enriches the style library of fully formed products,realizes methodological precipitation for the process conversion law from garment version to process version,and makes a breakthrough in the key process technology of the connection of double-layer special-shaped structure,so as to provide ideas and basis for the design,display,development and application of fully formed double-layer structure products.It is an important breakthrough in the application and development of fully formed products.
