Sewing Techniques For PVC Coated Nylon: Avoiding Coat Delamination

Sewing Techniques for PVC Coated Nylon: Avoiding Coat Delamination

PVC coated nylon is a popular material choice for outdoor gear and accessories due to its durability and water-resistant properties. However, when sewing with PVC coated nylon, there is a risk of coat delamination, where the PVC coating separates from the nylon fabric. This can lead to weak seams and reduce the overall quality and lifespan of your project. In this article, we will discuss various sewing techniques that can help you avoid coat delamination and create strong, lasting seams in your PVC coated nylon projects.

Choosing the Right Needle and Thread

One of the most important factors in preventing coat delamination when sewing with PVC coated nylon is choosing the right needle and thread. When working with PVC coated fabrics, it is recommended to use a heavy-duty needle, such as a size 16 or 18, to ensure that the needle can penetrate the thick PVC coating without breaking. Additionally, using a polyester or nylon thread that is designed for use with heavy fabrics can help to prevent the thread from tearing or breaking under the pressure of sewing through multiple layers of PVC coated nylon.

Adjusting Your Stitch Length and Tension

Another important consideration when sewing with PVC coated nylon is the stitch length and tension settings on your sewing machine. To prevent coat delamination, it is recommended to use a slightly longer stitch length than you would for standard nylon fabric. A longer stitch length will create fewer holes in the PVC coating, reducing the risk of the coating separating from the fabric. Additionally, adjusting your tension settings to a lower setting can help to prevent the fabric from puckering or distorting while sewing, which can also contribute to coat delamination.

Using the Right Sewing Machine Foot

When sewing with PVC coated nylon, using the right sewing machine foot can make a significant difference in the quality of your seams. A Teflon or roller foot is recommended for sewing with PVC coated fabrics, as these feet reduce friction between the fabric and the foot, helping to prevent the PVC coating from sticking to the foot and causing delamination. Additionally, using a walking foot or even feed foot can help to ensure that the layers of PVC coated nylon feed evenly through the machine, reducing the risk of uneven stitching and potential delamination.

Sealing the Edges of Your Fabric

To further prevent coat delamination when sewing with PVC coated nylon, consider sealing the edges of your fabric before sewing. Using a hot knife, soldering iron, or even a flame to carefully melt the edges of the fabric can help to bond the PVC coating to the nylon fabric, creating a stronger seam that is less likely to delaminate over time. Be sure to test your sealing method on a scrap piece of fabric first to ensure that it does not cause damage or discoloration to the PVC coating.

Practicing Proper Sewing Techniques

In addition to choosing the right materials and equipment, practicing proper sewing techniques can also help to prevent coat delamination when working with PVC coated nylon. When sewing seams, be sure to backstitch at the beginning and end of each seam to secure the stitches in place. Avoid pulling or stretching the fabric as you sew, as this can put stress on the PVC coating and cause it to separate from the fabric. Additionally, take your time when sewing through multiple layers of PVC coated nylon, being careful not to create too much bulk in the seams, which can lead to weak spots and potential delamination.

In conclusion, sewing with PVC coated nylon can be a rewarding experience, but it is essential to take the necessary precautions to prevent coat delamination and create strong, lasting seams. By choosing the right needle and thread, adjusting your stitch length and tension, using the right sewing machine foot, sealing the edges of your fabric, and practicing proper sewing techniques, you can avoid common issues with coat delamination and create high-quality projects that will stand the test of time. So, next time you reach for your PVC coated nylon fabric, keep these tips in mind and enjoy the process of creating durable, water-resistant items that will last for years to come.
