Bonded Nylon is the most common thread used for commercial apparel and non-apparel applications. We carry the most popular tex sizes in stock and can order what ever size you may need. The second most used thread in the industry is Bonded Polyester thread which we also carry in many colors and thicknesses. Our spun polyesters can be used in a wide array of applications. They are often used in outdoor products since the fibers are inherently able to resist UV rays. Again, if we don’t have the specific size you’re looking for, we can order it for you. The uses for nylon and poly include a long list of indoor and outdoor applications, which can be easily identified in the descriptive pictorial grid just above the section you are reading.
Leather Sewing Thread
Commercial leather sewing thread is typically used on a walking foot machine with a high grade industrial 110/16 to 110/18 needle. The right thread for interior applications will be a bonded nylon. The tex size will depend on the thickness of the leather you are using. The resin bonding agent found in the manufacturing process of the bonded nylon helped reduce friction in sewing. This allows for faster and smoother stitching during your production. We do not recommend waxed or common threads for leather sewing. However when it comes to outdoor leather products like a bike seat or the dashboard of a car which sees a lot of sunlight, you’ll want a polyester thread. The polyester fibers have better resistance to UV rays. A heavier thickness is strong enough to sew through several layers of additional material.
Heavy Duty Thread
Customers searching for heavy duty thread usually have specific uses in mind. The trick about heavy duty thread, is that most industrial threads over Tex 69, or Size 70, are heavy duty threads. More important than that is what the thread is being used for. Indoor or outdoor uses must also be considered. Please refer to our grid of images indicating end product types to decide which thread you will actually need.
