Somabond 40's Bonded Nylon Sewing Thread, 3200m Cone

Somabond 40's is a strong bonded nylon machine-sewing thread made for demanding professional upholstery and industrial sewing applications.

Supplied on a 3,200 metre cone, it offers high tensile strength, rot resistance and dependable sewing performance, making it particularly suitable for furniture upholstery, cushion manufacture, bedding and mattress production.

It is Status Fabrics' most popular sewing thread and is available in an extensive range of colour references for matching or coordinating with upholstery fabrics and other covering materials.

see the Sewing Threads & Barbobs range for professional machine-sewing threads and pre-wound bobbins.

Why Use Bonded Nylon Upholstery Thread?

Bonded nylon consists of nylon filaments treated so they remain together more effectively as the thread travels through the sewing machine.

The bonding treatment helps reduce separation of the filaments as the thread passes through:

• Thread guides
• Tension discs
• Take-up mechanisms
• The sewing-machine needle
• Multiple layers of upholstery material

This makes bonded nylon particularly useful for repeated machine sewing where a strong, durable construction thread is required.

Somabond 40's is suitable for high-speed sewing when used with an appropriate industrial sewing machine, needle and machine setup.

Suitable for Furniture, Cushions & Upholstery

Somabond 40's can be used for a wide range of suitable sewing applications, including:

• Sofa and chair upholstery
• Seat and back cushions
• Furniture covers
• Piped cushion seams
• Mattress borders
• Bedding manufacture
• Soft furnishings
• Automotive seat covers
• Campervan cushions
• Suitable vinyl and faux-leather covers
• Heavy woven upholstery fabrics
• Visible topstitching where appropriate

Strong Construction Thread for Upholstery Seams

Furniture covers can place considerable loads on sewn seams, particularly around seat cushions, corners, borders and areas repeatedly placed under tension during use.

A strong thread is therefore important, but thread strength is only one part of a reliable seam.

Also consider:

• Fabric strength
• Seam allowance
• Stitch length
• Needle condition
• Correct thread tension
• Material thickness
• Number of layers
• Sewing-machine capability

Even a high-strength bonded nylon thread cannot compensate for damaged fabric, inadequate seam allowance or incorrect machine setup.

Always test the complete seam before producing a finished cover.

Use it for Piped Cushion Seams

Piping is common throughout furniture and cushion manufacture and creates additional thickness within the seam.

A typical piped cushion seam may include:

• Main upholstery fabric
• Piping strip
• Piping cord
• Cushion border
• Folded seam allowances

Somabond 40's provides a strong construction-thread option for suitable piped upholstery seams.

Browse Piping Cords for piping used around seat cushions, back cushions, furniture borders and upholstered panels.

Always test the machine through the thickest area of the finished construction, particularly where seams, piping and corners intersect.

Sewing Cushion Covers with Zips

Removable seat and back cushion covers commonly incorporate a zip for access to the cushion interior.

When sewing zip panels, consider:

• Needle position
• Zipper-foot clearance
• Stitch length
• Thread tension
• Fabric thickness
• Piping around adjoining seams
• Alignment of the finished panels

Testing the complete construction on offcuts helps establish the correct machine settings before sewing the finished cover.

Somabond 40's or M36 PolyCotton Corespun?

For another professional upholstery thread, compare Somabond with M36 PolyCotton Corespun Sewing Thread.

The two products have different constructions.

Somabond 40's is bonded nylon, providing a strong synthetic construction thread with durability.

M36 PolyCotton Corespun combines a continuous polyester core with a cotton outer covering, giving it a softer surface and different sewing characteristics.

Consider:

• Upholstery material
• Required appearance
• Sewing speed
• Needle and machine setup
• Seam loading
• Cleaning conditions
• Exposure to moisture
• Whether stitching will remain visible

Neither thread should be treated as universally better. The correct choice depends on the specific upholstery job.

Choosing a Somabond Colour

Somabond 40's is available in an extensive range of manufacturer colour references.

Where the stitching will remain concealed within a construction seam, an approximate tonal match may often be sufficient.

For visible stitching, piping or decorative topstitching, colour selection becomes more important.

Consider whether the thread should:

• Blend with the main fabric
• Match the piping
• Coordinate with an existing seam
• Contrast deliberately
• Remain unobtrusive on patterned upholstery

Computer screens cannot reproduce thread colours with complete accuracy, so a physical comparison is preferable where an exact visible match is important.

Match the Thread to the Needle & Machine

Correct needle selection is important when sewing strong upholstery thread.

The needle must create sufficient space for the thread to pass through the material without excessive friction while avoiding an unnecessarily large hole.

Check:

• Sewing-machine needle system
• Needle size
• Needle point
• Thread path
• Material type
• Number of layers
• Seam thickness
• Stitch length
• Sewing speed

For woven upholstery fabric, vinyl, automotive materials or other specialist coverings, the appropriate needle point may also differ.

For hand-upholstery needles and related equipment, browse Needles, Pins & Skewers.

Pre-Wound Barbobs for Production Sewing

Compatible pre-wound bobbins can help reduce time spent winding bobbins during repetitive upholstery production.

For example, see:

• Black Barbob Type G, Box of 50
• Black Barbob Type L, Box of 50
• Brown Barbob Type G, Box of 50
• Brown Barbob Type L, Box of 50

Type G and Type L are different bobbin formats and are not interchangeable.

Always check the sewing-machine specification and bobbin case before selecting a pre-wound bobbin.

Construction Sewing & Overlocking Perform Different Jobs

Somabond 40's is primarily a strong construction thread.

For overlocking suitable raw fabric edges, Spun Polyester 120's Thread provides a purpose-specific alternative.

Overlocking is commonly used to neaten and stabilise raw woven fabric edges, while the main construction seam joins the upholstery panels and carries the working load.

For many professionally manufactured covers, the two operations complement each other rather than one replacing the other.

Sewing Machine Care

Upholstery sewing can produce lint, loose fibres and thread debris around the hook and bobbin area.

Regular cleaning and correct maintenance help keep a suitable industrial sewing machine operating smoothly.

Where lubrication is specified by the machine manufacturer, apply 125ml Sewing Machine Oil sparingly to the appropriate lubrication points.

Always test the machine on waste fabric after oiling to make sure no excess lubricant can transfer onto the finished upholstery.
