Color fastness, also known as dye fastness or color fastness.

Color fastness, also known as dye fastness or color fastness, refers to the degree of color retention in textiles during processing.

Resistance to various effects during use. The fastness is evaluated based on the color change and dye transfer of the sample and the uncolored lining fabric.

No Chinese content provided.

Textiles are subject to various external factors during use, such as light exposure, washing, ironing, sweat stains, friction, and chemical agents.

The role, some dyeing and printing textiles have been treated with special finishing processes, such as resin finishing, flame-retardant finishing, sand-washing, and abrasion finishing.

This requires that the color fastness of dyed and printed textiles be relatively maintained.

Colorfastness refers to the product's resistance to washing and abrasion.

So-called color fastness (abbreviated as color fastness), refers to the ability of dyed fabric to withstand external factors (compression, tension, rubbing, and light) during use or processing.

A variety of factors such as pressure, friction, water washing, rain exposure, sun exposure, saltwater immersion, saliva immersion, water stains, sweat stains, etc.

The degree of color fading is an important indicator of the fabric.

Commonly used are wash-resistant, light-fast, abrasion-resistant, perspiration-resistant, iron-resistant, and climate-resistant properties.

In practical operations, the testing items are primarily determined based on the product's application and product standards, such as in the case of wool textile products.

The product standards stipulate that the color fastness to sunlight must be tested, knitted underwear must be tested for perspiration resistance, and outdoor textiles, of course, must undergo testing for UV resistance.

Products such as awnings, lightbox fabrics, and canopy materials must, of course, be tested for their weatherfast color fastness.
