The textile and fashion industries are among the most environmentally burdensome, with textile waste accounting for a significant share of the impact. To reduce negative environmental effects, various sustainable design methods have been developed, among which the zero-waste design method holds an important place. This method is based on the optimal use of material already in the clothing design phase. The purpose of this diploma thesis was to investigate the effectiveness of zero-waste design in sweater production and to compare two approaches: classic design from knit fabric and design by knitting the pattern pieces on a knitting machine. In the experimental part, we first made three sweaters from knit fabric, designing and arranging the pattern pieces to minimise waste material. In parallel, we made two sweaters whose pattern pieces were knitted on a knitting machine and then sewn together. The starting point for both approaches was the same: geometric shapes, straight lines, and inspiration from the Japanese kimono. The results showed that the amount of textile waste was significantly lower when knitting the pattern pieces on a knitting machine compared to sweaters made from knit fabric. We found that knitting the pattern pieces allows for more precise control over material consumption and simplifies the tailoring phase. The results thus confirm that machine knitting technology has great potential for the development of sustainable clothing and represents an effective alternative to classic zero-waste design methods.
