The production process of Non-Woven Vest Bag is a meticulous and complex process. The following will introduce its production steps in detail:
1. Raw material preparation
Material selection: First, select high-quality non-woven fabrics as raw materials. Non-woven fabrics are mainly made of polypropylene fibers, polyester, etc. These materials are melted at high temperatures and formed into fibers through a special spinning process.
Material inspection: The selected non-woven fabrics are quality inspected to ensure that they are defect-free and meet production requirements.
2. Cutting and molding
Design: According to the purpose and needs of the vest bag, its size and pattern are determined, and computer-aided design software such as Photoshop, Illustrator, etc. are used for design.
Cutting: Place the non-woven material on the cutting machine and cut it precisely according to the designed size and pattern. This can be done by a non-woven bag automatic molding machine or a manual molding machine.
3. Printing and lamination
Printing: Use flexographic printing or screen printing technology to print the required pattern or text on the non-woven fabric. During the printing process, ink or dye is applied to produce the desired visual effect.
Lamination: For bags that need to improve visual effects and service life, lamination can be performed.
4. Sewing and Assembly
Sewing: Use an industrial sewing machine to sew the cut non-woven fabric parts. This usually involves sewing the sides, bottom and shoulders of the bag.
Assembly: Assemble the sewn parts according to the design pattern, including steps such as adding the bag bottom and sewing the bag mouth.
5. Hot Pressing and Inspection
Hot Pressing: Use a hot press to heat press the prepared Non-Woven Vest Bag to ensure that the shape and size of the bag are stable.
Inspection: Perform quality inspection on the finished product to ensure that it is flawless and meets the standards.
6. Packaging and Transportation
Packaging: Pack qualified Non-Woven Vest Bags for storage and transportation.
Transportation: Transport the packaged products to the destination to ensure that they are not damaged during transportation.
The entire Non-Woven Vest Bag production process requires strict quality control and technical operations to ensure the quality and performance of the final product.
