Leather as a durable material is always processed into bags, shoes, accessories, sofas, and jackets. Strong thread for leather is a necessary choice for being incorporated into the leather to support daily use. Moreover, leather products always symbolize quality and fashion, which demands a clean and polished look for the stitch line, especially when decorative stitch patterns are required. The even stitch and neat seam mean the sewn-in thread must be lint-free, abrasion resistant, and non-breakable. The Rongdu thread is quality enough to meet all the above requirements.

Type of Thread to Sew Leather
When sewing leather, it is important to use a thread specifically designed for this purpose. Leather is a thick and durable material, so it requires a strong and durable thread that can withstand the demands of sewing through the leather. Here are some types of industrial thread for sewing leather:

Polyester Thread: Polyester thread is a popular choice for sewing leather due to its strength and durability. Sewing polyester thread has good tensile strength and is resistant to abrasion, making it suitable for handling the thickness and toughness of leather. A polyester thread is also available in a wide range of colors, allowing for versatility in matching or contrasting with leather.

Nylon Thread: Nylon thick thread is another suitable option for sewing leather. It is known for its excellent strength and resistance to abrasion. Nylon sewing thread provides good stitch integrity and is capable of handling the demands of sewing through thick leather. It is available in various thicknesses and colors, making it versatile for different leather projects.

Bonded Nylon Thread: Bonded thread for sewing leather is a specialized type of nylon thread that is even stronger and more durable. It is made by bonding nylon filaments together, resulting in a thread with superior strength and resistance to abrasion. Bonded nylon thread is commonly used in heavy-duty leather sewing applications, such as upholstery or leather accessories.

Waxed Thread: Waxed thread is a type of thread that has been coated with wax, providing added strength, durability, and resistance to water. This makes it particularly suitable for sewing leather, as the wax coating helps the thread glide through the material and creates a stronger seam. Waxed embroidery thread is commonly used for hand-sewing leather, especially in leathercraft and saddle stitching.

Linen Thread: Linen thread is a natural fiber thread that has been used for centuries in leatherwork. It has excellent strength and durability, making it suitable for sewing leather. Linen thread is often preferred for traditional or hand-stitched leather projects, such as handbags, wallets, or leather shoes.

When choosing heavy duty thread for sewing leather and thick sewing thread for leather, it's important to consider the thickness, strength, and compatibility with your sewing machine or hand-sewing techniques. It is recommended to use a thread specifically labeled for sewing leather or heavy-duty applications. Additionally, selecting a thread color that complements or contrasts with the leather can enhance the overall aesthetic appeal of your finished leather projects, such as black sewing thread, white sewing thread, red sewing thread, blue sewing thread, pink sewing thread, green sewing thread, and gold sewing thread, etc.

What Thread To Use For Leather
Heavy Duty Bonded Nylon Thread
Leather thread is used for joining pieces of leather together. Bonded nylon thread is a superb choice to sew leather, and it comes in a variety of weights that pair well with different weights and thicknesses of leather. Bonded nylon is a strong thread, and the bonding process adds strength and reduces friction, making smooth and continuous stitches neat and even seams.

Tex 45 and Tex 70 Bonded Nylon Thread
Soft leather, such as that for a wallet, can be sewn with tex 45 bonded nylon thread or tex 70 bonded nylon thread. These two thicknesses are on the lighter weight scale and are typically used when stitches are meant to be close together or decorative in nature.

Tex 90 Bonded Nylon Thread
When sewing on a little thicker leather, we suggest sewing with bonded nylon tex 90. If the sewn leather will bear a load or be used for furniture, then a tex 135 thread could be considered. Tex 135 thread is also made for a decorative reinforcing thread when used to accent the seam.

Tex 210 or Tex 270
For heavy leather, a thicker thread like tex 210 or tex 270 is recommended. When the two sizes are applied, the stitch length should be lengthened to help create even spacing.
