Manufacturing method for seamless bag

Abstract

A manufacturing method for a seamless bag includes the steps of: forming yarns by adding an appropriate amount of setting yarns to natural or chemical fibers; weaving the yarns into a seamless bag body; accommodating the bag body around a mold having a shape of a bag; heating the mold accommodated by the bag body by means of steam or other heat sources for allowing the bag body to be evenly heated; cooling and setting the heated bag body and the mold by cold air for forming a seamless bag; and stitching and shaping the bag. According to the above manufacturing method, a seamless and integral handbag is completed, while also offering consistent manufacturing process for accelerating manufacturing speed of the handbag.

1 . A manufacturing method for a seamless bag comprising the steps of: 
 a) weaving the yarns into a seamless bag body;    b) accommodating the bag body around a mold having a shape of a bag;    c) externally heating the mold accommodated by the bag body by means of steams or other heat sources, such that the bag body receives heat from an exterior to an interior;    d) cooling the heat mold and the bag body by means of cold air from the exterior to the interior, and setting the bag body for forming a seamless bag; and    e) completing a seamless bag by stitching and shaping.    
   
   
       2 . The manufacturing method for a seamless bag, wherein the bag body is accommodated around a hollow mold, and heated from an interior to an exterior by means of steam or other heat sources, such that the bag body is evenly heated from the interior to the exterior; and cold air is guided into the hollow mold for the cold air to cool and set the heated bag body from the interior to the exterior.
