What Are The Production Steps Of Non-woven Handbags?
Non-woven handbags are eco-friendly and affordable alternatives to traditional bags made of materials like leather, cotton, and plastic. Non-woven bags are made of polypropylene (PP) fabric, which is a thermoplastic polymer that is widely used in the packaging industry. In this article, we will discuss the production steps of non-woven handbags.
Step 1: Material Selection
The first step in the production of non-woven handbags is the selection of raw materials, including polypropylene resin, masterbatch, and additives. These materials are mixed and melted in an extruder, which produces the PP fabric with a thickness of about 60-100 GSM (grams per square meter).
Step 2: Spinning
The next step is spinning, which involves forming the extruded PP into a fine filament by spinning it through small holes using a spinneret. The filaments are then cooled, stretched, and solidified to form a web of fibers.
Step 3: Web Forming
The web is formed using two methods: dry-laid and wet-laid webs. In the dry-laid method, the spun-bonded fibers are randomly laid out on a conveyor belt, while in the wet-laid method, the fibers are mixed with water and laid out on a wire screen.
Step 4: Bonding
The web of fibers is then bonded together using heat, pressure, or chemicals. Heat bonding involves passing the web through a heating oven, which melts the fibers and causes them to bond together. Pressure bonding involves using rollers to press the fibers together, while chemical bonding involves adding a bonding agent to the fibers.
Step 5: Cutting
The bonded web is then cut into the desired size and shape of the non-woven handbags, using a cutter, which can be a die-cut machine or a computer-controlled cutter.
Step 6: Printing
The non-woven handbags can be printed using different methods, such as screen printing, offset printing, and heat transfer printing. Screen printing involves applying ink onto the bag through a mesh screen, while offset printing involves transferring ink onto the bag through an intermediate surface.
Step 7: Sewing
The final step is sewing the non-woven handbags together using either a manual or automated sewing machine. The bags can be designed to have various handles, such as a loop handle, a foldable handle, or a long shoulder strap.
Benefits of Non-woven Handbags
Non-woven handbags have several advantages over other types of bags. They are:
• Eco-friendly: Non-woven handbags are made of materials that are biodegradable and do not harm the environment.
• Lightweight: Non-woven bags are lightweight, which makes them easy to carry and transport.
• Durable: Non-woven bags are strong and durable, which makes them suitable for carrying heavy items.
• Affordable: Non-woven bags are relatively inexpensive to produce, which makes them affordable for businesses and consumers.
Conclusion
The production of non-woven handbags involves several steps, including material selection, spinning, web forming, bonding, cutting, printing, and sewing. Non-woven handbags are eco-friendly, lightweight, durable, and affordable alternatives to traditional bags made of materials like leather, cotton, and plastic. With the increasing demand for eco-friendly products, non-woven handbags have become a popular choice for businesses and consumers around the world.
