Wholesale Sewing Threads

Polyester, poly-cotton and cotton sewing threads for industrial sewing – in a wide range of colours and thicknesses, wholesale from Polkom, a garment accessories manufacturer.

Sewing threads for industrial and garment production

Sewing threads join the parts of a garment and determine how long the product will last. A good sewing thread is smooth, even in thickness and strong and elastic enough not to break at high machine speeds or during wear. Polkom, a manufacturer and wholesaler of garment accessories, supplies sewing threads wholesale to sewing units, fashion brands, home textile manufacturers and ateliers, and helps choose the right article for each material.

Types of sewing thread

Polyester sewing threads

The most widely used type. Polyester is strong, resistant to light and washing, and practically does not shrink. It suits most fabrics – from fine shirting to heavy trousers and jackets.

Core-spun threads

Here a polyester filament core is wrapped in cotton or polyester fibres. They combine the strength of polyester with a matt look and good machine performance. They are preferred for jeans, workwear and products with heavily loaded seams.

Cotton sewing threads

Made from cotton, usually mercerised for greater smoothness and sheen. Suitable for linen, cotton and wool and for products that will be dyed after sewing. More about them in the cotton threads section.

Textured threads for overlock

Bulky, soft polyester or polyamide threads for the loopers of overlock and coverstitch machines. They cover the edge well, are elastic and pleasant to the touch – ideal for jersey, lingerie and sportswear.

Thickness and needle choice

Sewing thread thickness is given as a ticket number. The higher the number, the finer the thread.

  • Ticket 180–150 – very fine fabrics, lingerie, silk.
  • Ticket 120 – the all-round number for shirts, dresses, blouses and most garments.
  • Ticket 80–75 – heavier fabrics, trousers, jackets.
  • Ticket 40–20 – decorative and heavy-duty seams, denim, canvas.

The thread must match the needle – a thread that is too thick in a thin needle frays and breaks, while one that is too thin in a thick needle produces an uneven seam.

Applications

  • clothing – shirts, trousers, dresses, jackets and coats;
  • jersey, lingerie and sportswear;
  • workwear and uniforms;
  • home textiles – bed linen, curtains, tablecloths;
  • bags, backpacks and technical textiles.

Colours

Sewing threads come in a wide range of colours, including the core neutral shades most often used in production. Where needed, we match the colour to a fabric sample. We also keep contrasting colours for decorative stitching.

FAQ

Frequently asked questions

Which sewing thread is the most versatile?
For most garments, the most versatile option is polyester sewing thread in ticket 120. It is strong enough for everyday seams, runs well on industrial machines and does not shrink in the wash. For jeans and heavily loaded seams, heavier threads or core-spun threads with a polyester core are recommended.
What thread should I use for overlock?
For the overlock needles, polyester sewing thread in ticket 120 is usually used. For the loopers, especially on jersey and lingerie, a textured thread is suitable – it is bulky, soft and elastic. It covers the edge well and is pleasant to the touch without restricting the stretch of the fabric.
Do polyester threads shrink in the wash?
Polyester sewing threads practically do not shrink and keep their length and colour in normal washing. That is why they are suitable for most garments. For products that will be washed or dyed at high temperatures, we will advise you on the most suitable type of thread.
