Extra Strong Bonded Nylon Thread #138 Tex135 16 OZ - Durable 3000yd

In this review the HILOHILO Extra Strong Bonded Nylon Thread #138 Tex135 is evaluated for heavy-duty stitching tasks where strength and smooth feed matter most. The bottom line: this 1 lb, 3000 yd cone is aimed at leatherworkers, upholstery pros, and serious DIYers who need a dependable, abrasion-resistant thread that resists untwisting and handles high-temperature sewing. Its bonded chemistry and lubricant treatment make stitch runs smoother and reduce breakage, which is the single biggest reason a professional would pick this thread over lighter hobby thread.

Key Features

• Premium nylon 6.6 construction: delivers consistent tensile strength so seams hold up under repeated stress.
• Bonded and coated: the unique bonding chemistry prevents single-thread untwisting and peeling for cleaner, more reliable seams.
• Lubricated for smooth passage: specially formulated lubricants reduce skipped stitches and minimize needle heat during long runs.
• Commercial size and length: the 1 lb cone with 3000 yd capacity suits large projects and reduces spool changes for production work.
• High-temperature dyeing: colorfast treatment resists fading so sewn goods maintain appearance after exposure and cleaning.
• Good stretch and abrasion resistance: slight elasticity improves stitch tightness while resisting surface wear on high-friction applications.

Who It's For

The Extra Strong Bonded Nylon Thread is best for leather crafters, upholstery technicians, automotive interior repair, and makers of heavy canvas goods who need a commercial-grade thread that will not fail under load. It suits projects like seat repairs, saddles, luggage, and outdoor gear where durability and resistance to abrasion are critical.

Those working on delicate fabrics, fine garments, or detailed embroidery should look elsewhere for finer, less bulky thread options; this product is optimized for heavy materials and industrial needles such as 140/22 or 160/23 rather than lightweight domestic sewing.

Pros & Cons

Pros

• Exceptional strength and durability from 100% premium nylon 6.6 construction.

Cons

• Thicker #138 Tex135 size can be too heavy for delicate fabrics and requires large needles.
• One-pound cone is bulkier to store for hobbyists with limited space.

Frequently Asked Questions

Is this thread suitable for leather hand sewing?
The thread is designed for heavy-duty use and works well for both machine and hand stitching on leather, though large needles are recommended.

Will the color fade after washing?
High-temperature dyeing provides good colorfastness so the thread resists fading under normal cleaning conditions.

Can this be used on home sewing machines?
It can be used on heavy-duty home machines if fitted with the correct large needle and tension adjustments; industrial machines are the ideal match.
