Two-Ply 210D/2 Bonded Nylon Thread for Leather Shoe Seams
210D/2 Bonded Nylon Sewing Thread
Product Details
MH 210D/2 bonded nylon sewing thread is a two-ply bonded polyamide filament thread used to stitch leather shoe uppers, linings and decorative seams on industrial sewing machines.
The 210D/2 build twists two 210-denier plies together, so the finished thread body is slimmer than a three-ply thread of a comparable strength class and sits in the leather perforation with less crowding.
MH dyes the thread across a wide shade range so upper, lining and decorative stitching can be matched or deliberately contrasted within one style, and takes custom colour and count development for leather footwear, leather goods and upholstery production.
Key Selling Points
Finer seam appearance: The two-ply body of MH 210D/2 bonded nylon sewing thread lets close-pitch topstitching on leather uppers read as a fine, even seam line rather than a raised cord.
Elastic recovery: Nylon lets the thread stretch and return as the upper is lasted and flexed, helping seams over curved vamps and quarters keep their shape through assembly and wear.
Abrasion resistance in wear: Polyamide filament stands up to the repeated rubbing that eyestay, collar and decorative seams see on finished leather shoes.
Color matching across shoe parts: MH dyes bonded nylon thread across a broad shade range, so upper, lining and decorative stitching can be matched to one another or contrasted on purpose.
Certified production: MH bonded nylon sewing thread is produced under OEKO-TEX® certification, which supports footwear buyers who need compliance documentation for their supply chain.
Reliable bulk supply: MH manufactures bonded nylon thread in-house for repeat footwear and leather-goods programmes, with custom color and count development available for ongoing orders.
Nylon Bonded Sewing Thread
Nylon bonded sewing thread is made of polyamide 6.6 synthetic fiber, popular name Nylon 6.6 or 6 synthetic fiber, through a special process to bond while twisting the fiber, then sticking and finalizing all-fiber together like one. While sewing, the bonded thread does not disentwine, not cottony, has high resistance to abrasion.
The sewing effect is wonderful due to the advantage of nylon material and the effective disposal of lubricants.
