RESEARCH ON SOME TECHNOLOGY FACTOR’S EFFECT OF JACKET’S WAVY SPLINT ZIPPER

Abstract

Wavy splint zipper is one of important criteria in checking jacket product quality when
manufacturing in industrial process. Determining the optimal technological parameters to
minimize the wave buckle brace phenomenon. We have studied a number of factors
affecting the wavy splint zipper phenomenon. The study was conducted according to the
method of multivariate orthogonal experimental planning with the help of Design Expert
11.0 software to design the experiments, process data and establish the experimental
regression equations. Determined the effects of 4 elements at the same time: the length of
shirt, stitch length, compression presser foot, the height of tooth, compression presser foot,
the height of tooth bar to wave brace height. The research’s result showed that the splints
shirt length has the most effect on the height of wave buckle brace. Applying the
optimization model the research has identified that the quadratic model has the statistical
significant. The research’s results have indentified the optimal machining technology to
reduce the level of the splint wave: brace strip = 553.467mm ( converted to the ratio
between the length of the fabric and the buckle is 100.63%) stitch length = 3.453mm,
presser foot compression = 28.535mm, tooth bar height = 0.978mm.
