Abstract:

In order to improve the accuracy of calculating the working hours of the garment template sewing process, by the classification study on the sewing actions of the template, 19 template sewing action codes were developed for the general sewing time (GST) software. Firstly, this paper summarized the standard actions of 12 automatic template and 7 manual templates during the template sewing process. The modapts time process was used to decompose action elements,  the time value of those actions were calculated. Secondly, 19 actions were coded according to the code rules of the general sewing time software. Finally, modapts time value was transformed into general sewing time value to obtain the standard time value of the new actions. By the comparison experiments between new and old codes calculating results of GST system and the real measured times, the results show that the calculation accuracy of using new template coding is more than 90%. It is show that the new codes can more accurately calculate the working hours of the template sewing process.

Key words: standard working hour, garment template, modapts, general sewing time
