PENGARUH KELAS LIPATAN JAHITAN (SEAM) TERHADAP PEMAKAIAN BENANG POLYESTER SPUN 40/2 PADA MATERIAL KAIN TENUN ANYAMAN KEPER GRAMASI 200-220 g/m2

Seam or seam folds, is one of the variables that affect the consumption of thread usage in the clothing production process. ISO 4916:1982 classifies seam folds into 8 classes, namely from class 1 to class 8. At the Surakarta Textile and Textile Product Industry Community Academy, the implementation of the clothing production process is carried out during practical courses, and one of the outputs is a student uniform with woven fabric material using a keper woven construction with a grammage of 200-220 g / m2, using polyester spun yarn 40/2 sewing thread. The research methodology was carried out by measuring thread consumption in 8 seam classes, then the measurement data was processed using statistical tests in the form of normality tests and one-way ANOVA. The result is a normally distributed experiment with data from each seam class being homogeneous, and the results of the average analysis show that between one seam class and another, there is no significant effect on thread usage. The study results of the sample length with the average thread length show that the minimum thread usage requirement for each seam class is twice the length of the sample.
