Rapid design and algorithm implementation for knitted sweater pattern

Abstract

Sweater pattern design plays a crucial role in practical production, determining whether the finished products can meet the requirements of customers. In addition, pattern-designing is also a vital link in the production of sweaters, affecting the development cycle and final quality of products. For this reason, this work proposed two different kinds of algorithms for sweater pattern design: synchronous filling algorithm and asynchronous filling algorithm, so as to realise the rapid design of sweater pattern in Computer-Aided Design (CAD) system by reducing the complex technique calculation. Firstly, the data structures of specifications and styles were established respectively based on the technological characteristics of sweaters, and then the algorithms for sweater pattern-generating were implemented by using C+ + programming technology. At last, the running time of each algorithm was tested to analyse the performances of the algorithms under the same filling scales and different filling scales, respectively. The results showed that the execution efficiency and stability of synchronous filling algorithm are better than that of asynchronous filling algorithm.
