Materials React to UV Rays

UV degradation of sewing threads is concerned with the physical and chemical changes resulting from irradiation of the base polymers by ultra violet or visible light.
The energy absorbed leads to degradation of the polymeric chain and a loss of strength in the sewing thread. It also attacks the dyes concerned leading to fading or spotting of the thread colour.
UV ray affects many natural and synthetic polymers including some rubbers, neoprene and polyvinyl chloride (PVC). With too much exposure, these materials can: Fade color; Lose strength; Become less flexible; Crack; Disintegrate.
Certain inks and dyes can be affected as well. This problem, called photodegradation or phototendering, causes objects like textiles, artwork and polymers to: Change color; Fade in color; Produce a chalky surface

Anti-UV Sewing Thread

Many additives are available e.g. copper compounds, UV absorbers, and anti-oxidants are effective in slowing down the degradation process.
Additives such as UV absorbers have much more effect if they are added to the raw yarn during spinning rather than afterwards e.g. during dyeing as applying here can allow it free to migrate to other components after stitching, negating its effect.
The anti-UV sewing thread can prevent the sunlight and reduce the absorbing of ultraviolet rays to prevent its degradation, ensure the mechanical properties of the thread like strength, and also improve the sunlight fastness of the thread.

Color Cards

These are made with actual thread samples so you have a perfect color match to choose the desired thread.


The anti-UV sewing thread are suitable for military protective clothing, outdoor tents, umbrella, beachwear, swimwear, hats, outdoor sun protection clothing and sports equipment.

Beach Shade

Anti-uv sewing threads won't lose their properties over time under the influence of UV radiation, salt water and other weather conditions.


For humans, suntan and sunburn are familiar effects of exposure of the skin to UV light, along with an increased risk of skin cancer. Sprotswear made of anti-uv materials becomes a trend.
Outdoor Upholstery

Outdoor Upholstery

Polyester thread does better than nylon when you are sewing things that have prolonged exposure to sunlight (UV rays) and moisture.
