Content heating process on the edge of fabrics
A approach of producing bendy polypropylene material bags with heat fused seams comprising providing material portions, in which each material piece has a coated edge and an uncoated edge; arranging the material portions in order that a coated edge of one material piece faces a coated edge of another cloth piece; choosing a place of fabric to be joined for forming a seam or joint; applying warmness to the region to be joined that is less than the melting factor of the fabrics, for forming one or more seams or joints and wherein the heat-fused seams or joints of an ensuing polypropylene bag retains at the least 85% of the material electricity without using sewing machines.
Strength on the edge of the fabric is higher:
The heating process increases the strength of the fabric even more. Heating on the edge of fabric forms a tough, bendable, lightweight sack that can manage heavy materials with ease. The polypropylene fabrics are extremely focused on heating, sealed and crushed process to achieve utmost strength while maintaining the required flexibility of fabrics to fit the needs of the marketplace.
Heated fabric at temp 220 to 230°C:
We heat the fabric at the defined temperature of 220 to 230 degree Celsius. The heating enhances the mechanical properties, like high tensile strength, favourable abrasion resistance, high temperature resistance, and high gloss. This significantly opts better creep performance even at temperatures up to 80°C. Therefore this allows for example hot filling with industrial goods, such as cement on a production line.
Stitching Made Easier:
Sewing machines are used widely for making bags. These machines are used and operated by several weavers having the appropriate knowledge to handle these sewing machines. As the weavers can run the machine at speed of several thousand stitches per minute with many mechanical parts, this results several functional issues and the most common one is needle breakage. With all the process that makes the fabric strong, the section where stitching comes to the picture is also considered important. Even where the fabric is strong, the stitching is made easier for the weavers. This is also because stitching is done at a great speed with many mechanical parts. There is a high frequency of parts breakage and needle breakage. Even the slightest issue can stop the production of that particular machine for an hour or more. Escaping every such hustle for the weavers, the fabric is maintained is a way that is good enough for needles and is machine friendly.
