Work rain coat, particularly those made of PVC/polyester or PVC/polyester/PVC, are popular choices for workers in harsh conditions. These work rain coats provide excellent waterproof and windproof protection. However, raincoat manufacturers in China face some challenges regarding quality control. Two main issues are fabric durability and heat-sealed seams. These problems compromise the suit’s overall effectiveness. Let’s explore these issues and how manufacturers can solve them.
Work Rain Coat’s Fabric Durability
The most common problem with PVC work rain coats is the fabric’s tendency to tear easily. The PVC layer, while providing waterproofing, is often too thin or lacks adequate reinforcement. PVC work rain coat manufacturers should consider increasing the thickness of the PVC layer to improve durability. Thicker PVC provides more resistance to wear and tear, making the work rain coat more robust. Manufacturers should opt for PVC layers of 0.32mm, 0.35mm, or thicker, as these offer better protection against punctures and rips. Thicker PVC also improves the overall strength of the material.
In addition to increasing thickness, PVC work rain coat manufacturers and suppliers in China should focus on using a denser and stronger polyester mesh fabric. Polyester is already a durable fabric, but increasing the mesh density enhances its tensile strength. A higher-quality polyester base fabric will not only increase the overall durability of the suit but also prevent the fabric from stretching and tearing under stress. The combination of thicker PVC and strong polyester will result in a more long-lasting work rain coat.
Heat-Sealed Seam Problems
Another critical issue with PVC work rain coats is the heat-sealed seams. While heat sealing is effective in ensuring waterproofing, these seams are vulnerable to tearing over time, especially under heavy use. This is a common problem with PVC/polyester work rain coats and PVC/polyester/PVC work rain coats. The seams, if not reinforced properly, are the first part to break down due to constant stress.
To address this issue, manufacturers should reinforce these seams with additional layers of PVC or by using higher-quality sealing techniques. Using high-density PVC for the seam areas can significantly improve the strength and resistance to tearing. Additionally, manufacturers should ensure that the seams are sealed more effectively by using advanced sealing technologies. Reinforcing the pocket flaps and other vulnerable areas will also improve the overall durability of the work rain coat.
Choosing the Right PVC Grade for Work Rain Coat
PVC comes in various grades—A, B, and C—based on the quality of raw materials and production processes. Grade A PVC is made from virgin material with high-quality additives, ensuring superior weather resistance and mechanical strength. Grade B PVC contains a moderate amount of recycled material, making it less durable than Grade A. Grade C PVC, often used in low-end products, contains a high percentage of recycled material and is prone to degradation.
To ensure durability and longevity, PVC work rain coat manufacturers in China should prioritize using Grade A PVC. The higher purity and strength of Grade A PVC make it ideal for heavy-duty work rain coats that need to withstand harsh working conditions. It also offers better UV resistance and aging properties, which are essential for outdoor use. By opting for Grade A PVC, manufacturers can significantly reduce the frequency of tears and the breakdown of seams.
Reinforcing Critical Areas
Specific parts of the PVC work rain coat are more susceptible to damage. One such area is the pocket flap, which often experiences tearing due to constant wear. PVC raincoat designs should reinforce such vulnerable areas with additional layers of PVC or stronger stitching. By reinforcing these areas, manufacturers can improve the overall durability of the work rain coat.
Another area that needs attention is the reflective raincoat sections, which are often exposed to wear and tear. Manufacturers should use better-quality reflective material that won’t degrade or peel off after extended use. Additionally, the reflective sections should be stitched securely to prevent them from coming loose.
Production Process and Control
The production process plays a significant role in determining the quality of PVC work rain coats. If the manufacturing process is not carefully controlled, it can lead to defects in the material and seams. PVC work rain coat manufacturers and suppliers in China must invest in better quality control procedures to ensure uniformity in material thickness, seam sealing, and overall construction.
Manufacturers should also pay close attention to the consistency of the PVC coating. Any defects, such as bubbles or uneven coatings, can weaken the overall structure of the work rain coat. By improving production techniques, manufacturers can ensure a higher-quality end product that meets the needs of industrial and commercial users.
Conclusion
PVC work rain coats are a vital piece of protective gear for workers in wet and harsh environments. However, PVC work rain coat manufacturers in China face significant challenges with fabric durability and heat-sealed seams. By increasing the PVC layer thickness, using higher-density polyester, and opting for higher-quality PVC materials, manufacturers can enhance the durability of these suits. Reinforcing critical areas and improving the production process will also go a long way in improving quality. With these solutions, PVC/polyester work rain coats can become more durable and reliable, providing better protection for workers in industrial settings.
Investing in these improvements will not only address current quality issues but will also help manufacturers produce superior PVC raincoats that meet the growing demand for reliable, long-lasting work rain coats.
