dc.description.abstractThis paper presents the findings of the study of building and completion of a standard database on the operation process and sewing time for 02 typical products from knitted fabrics, namely Polo-Shirt and TShirt. The study process is carried out based on applying MTM (Methods Time measurement) standard time analysis method and predetermined time system GSD (General Sewing Data). In this research, we have inherited the results from previous studies including Classifying the main parts sewing linkages, formulated sewing technology process and theoretical analysis of the process of manipulating sewing of the main parts, linkages of the 02 classical textile products including Polo-Shirt and T-Shirt by MTM standard time analysis method and GSD predetermined time system; The studies work of the group of authors on the experimental research content determines the simultaneous influence of a group of factors: distance to place the sewing element (cm), the rotation angle of the sewing element (˚), the size of the sewing element, the number of element layers involved in the sewing, the light intensity (lux) and the skills of sewing workers (grade worker) to the sewing time of knitting products and research simultaneous influences of a group of technological factors including: seam length (cm) and stitches per centimeter (stitches/cm), experiment on 4 sewing devices such as 1-needle lockstitch machine, overlock machine (1 needle and 3 threads) and (2 needles and 4 threads), coverstitch machine (2 needles and 3 threads); and with 3 kinds of single jersey fabrics, which are thin, medium, and thick fabrics to sewing time on the machine of Polo-Shirt and T-Shirt products. The above research results show that there is a big difference between the actual values and theoretically calculated values according to MTM method, GSD predetermined time system, the authors have determined a set of adjustment coefficients for the former and the latter for two values of sewing preparation operation time and sewing time on the machine. We have tested the above research results in 03 enterprises: Hanoi Star Fashion Co., Ltd., Tinh Loi Garment Company and Ha Nam Hanosimex Company Limited and received a lot of practical comments from businesses.cs
