Numerical optimisation of mechanical reinforcements of weak spots in textiles and garment

Abstract

Purpose -The purpose of this paper is to investigate and illustrate the possibilities of a systematic engineering approach in the design of mechanical reinforcements in garments. A mechanical reinforcement can be designed using optimisation strategies. Design/methodology/approach -In this work, an iterative algorithm for minimum search based on parabolic approximations is proposed and applied in the optimisation of mechanical reinforcement in a selected model problem of a buttonhole type. Findings -Optimisation algorithm based on parabolic approximations, in conjunction with the finite element analysis, offers some promising possibilities as support for the decision-making process in the design of mechanical reinforcements. The selection of optimisation criteria -influence parameters and corresponding weight factors -remains of course to be studied and implemented by the clothing engineering experts.Research limitations/implications -The intention in future work should be to optimise two or more geometric parameters simultaneously (multidimensional optimisation), and to produce a computer program for an automated optimum search. Practical implications -The contents of the paper could be useful for the experts in clothing engineering in the process of design or selection of the reinforcements of weak spots in textiles and garments. Originality/value -This paper provides optimisation routes to the weak sports of mechanical reinforcements in textiles and garments.
