Cotton Threads Wholesale

Cotton threads for natural fabrics

Cotton threads remain the preferred choice when a product is made of cotton, linen or wool and when the seam needs to look natural. Cotton is matt or slightly satin, soft to the touch, withstands high ironing temperatures and takes dye just like the fabric. That is why cotton thread is indispensable for garments that are dyed after sewing. Polkom manufactures and delivers cotton threads to brands with natural collections, sewing factories and manufacturers of home textiles and furniture.

Types of cotton threads

Mercerised cotton threads

Made of 100% high-quality cotton treated by mercerisation. This makes the thread stronger, smoother and slightly lustrous, and the colour looks richer. They are available in several thicknesses – from fine ones for shirts and dresses to heavier ones for denim and decorative seams – and on a colour card. A special lubrication improves needle passage in industrial sewing.

Organic cotton threads

Sewing and embroidery threads made of 100% long-staple organic cotton, grown without synthetic pesticides, herbicides and GMOs. The long fibre gives greater strength and a long seam life, and the thread is soft and biodegradable. Suitable for lingerie, childrenswear, sportswear, denim, home textiles and eco-oriented collections.

Core-spun threads with a cotton wrap

In these threads a polyester filament is wrapped in cotton fibres. The core provides strength, while the cotton protects the polyester from heating in the needle and from the iron. The seam has a natural cotton look but lasts much longer than classic cotton thread. When denim is washed, these threads create the typical worn effect and come close to the tone of the fabric. More about them in the denim threads section.

Advantages of cotton threads

• Resistance to high ironing temperatures – cotton does not melt.
• Optimal dye uptake when finished products are dyed.
• Natural matt look and soft touch.
• Good resistance to abrasion and bleaching with the right choice of item.
• Suitable for collections made of natural and organic materials.

Applications

• shirts, suits, dresses and linen and cotton clothing;
• garments dyed after sewing (garment dye);
• jeans and workwear;
• lingerie, childrenswear and sportswear;
• leather goods, furniture and home textiles.

When cotton is not the best choice

Cotton is less elastic than polyester. For knitwear, swimwear and sportswear, where the seam stretches, it is better to choose polyester or textured sewing threads. For products exposed to moisture and sunlight for long periods, we also recommend synthetic threads or a core-spun version with a cotton wrap.

Colours and combinations

Cotton threads are available in natural, pastel and rich tones on a colour card, and for larger quantities matching to a sample is possible. For products that will be dyed, sewing is usually done with unbleached or white thread, which takes the colour together with the fabric. Cotton threads combine well with natural accessories such as corozo buttons and cotton labels.
