Study on Evaluation of Woven Garment Stitch Crack

A variety of stress cracks appear in the garment seam, which affects the appearance and the seam strength. In this paper, the indicating methods of seam cracks were presented by identification and analysis of a variety of seam cracks on woven garments. The regression equation of seam crack recognizable rate was listed through different kinds of seam cracks observed and distinguished by inspectors. The influence on crack recognizable rate by the size and the colour of the crack was also analyzed in this paper. The objective assessment of fracture strength was made by testing the fracture strengths of five kinds of fabrics in warp, weft and 45 ° oblique direction using self-made needle crack testing device. This paper has certain significance for fabric designing and clothing production technology.

Study on Relationship between Mechanical Properties and Seam Smoothness Worsted Fabric

The instability of seam smoothness for worsted fabric is always a big problem in suit industry. With substantial development and application of new worsted fabric as well as the comprehensive application of various fiber materials，it is difficult to control seam smoothness of suit, creating the quality of suite to descend and adversely affecting the brand development in suit industry. The purpose of this paper is, therefore, intending to study the relationship between worsted fabric mechanical properties and garment seam smoothness grade as well as the effect of environmental air temperature and humidity conditions on smoothness of seam sample, by selecting several pieces of worsted fabrics and testing their mechanical properties through FAST. The goal of this paper is to facilitate textile and garment enterprises to improve their own textile process and finishing as well as the sewability of worsted fabrics.
