FB Stitch-Bonding Machine

How Stitch Bonding Works

Stitch bonding uses warp knitting steps to join fibrous webs with thread, without adhesive and without heat. The machine stitches the layers together directly, which keeps the process fast and clean.

FB Model: Working Widths and Gauge Options

The FB Stitch-Bonding Machine is available in working widths of 2000 mm, 2800 mm, 3600 mm, 4400 mm, 4800 mm, 5400 mm and 6000 mm, with gauge options of F7, F12, F14, F16, F18, F20 and F22.

Drive and Beam Configuration

The pattern drive uses an N-drive with a disc and a tempi gear system, and the machine can run with 1 or 2 warp beams depending on output needs, with a maximum flange size of 30 inch. Yarn let-off is electric, driven by a geared motor with its own control unit.

Motion Control

An onboard computer coordinates the main drive, yarn feed and fabric take-up, with process data shown on a touch screen for the operator.

Cross-Industry Applications

Nonwoven fabric from stitch bonding is used in automotive interiors such as seat covers, door panels and headliners, in mattress fabrics, in geotextiles for erosion control and drainage, in protective clothing including safety suits, gloves and uniforms, and in air and water filter media.

Advantages Over Adhesive or Thermal Bonding

Because the process joins layers with thread instead of glue or heat, it runs without the energy cost of a heating stage and without the material waste that comes from spilled or dried-out adhesive. The stitch holds the fabric in place, resisting slipping and excess stretch, which keeps the fabric’s shape and tear resistance over time.

Medical Bandage Production

Stitch-bonding machines produce medical bandages by interlocking fiber webs with yarns using specialized knitting elements. The machine takes loose fiber webs, such as viscose, polyester, or polypropylene, and uses knitting needles to stitch through and consolidate the material.

Specialized variants, such as the binding stitch-bonding machine, can sew spandex filaments into spunlaced or spunbonded non-woven fabrics to create elastic medical bandages. Manufacturers can also apply polymer glue particles or treatments to both sides of the stitched fabric to produce self-adhesive or high-support medical bandages.

The resulting fabrics are consistent and lightweight, suited to medical bandages, dressings, and hygiene products where uniform texture and breathability matter, while the stitching increases the fastness, toughness, and structural stability of non-woven medical textiles without making them overly bulky.
