The color fastness and wrinkle resistance of fabrics are important indicators for evaluating their quality. The following is a detailed introduction to the evaluation methods of these two aspects:
1. Color fastness evaluation:
Color fastness refers to the Whether the dye is easy to fade or stain to other materials under conditions such as washing, friction, sweat, etc. Common evaluation methods include:
– Washing fastness: by testing the color fastness of fabrics under different washing conditions, such as home washing, dry cleaning, water washing, etc.
– Rubbing fastness: Rub the fabric with a Labray brush or box tester to see if the fabric fades.
– Sweat fastness: Drop sweat containing acidic or alkaline salts on the fabric to detect its effect on the color of the fabric.
These evaluation methods can be tested according to international standards (such as ISO, ASTM, etc.) and are usually expressed by numbers. The higher the value, the better the color fastness.
2. Wrinkle resistance evaluation:
Wrinkle resistance refers to whether the fabric is prone to wrinkles during wearing and whether it can return to flatness Ability. Common evaluation methods include:
-Wrinkle resistance assessment: By folding, compressing and other operations on the fabric, observe whether it is prone to obvious wrinkles, and measure its ability to return to flatness.
– Anti-wrinkle evaluation after washing: The wrinkle resistance of the fabric is tested after washing to detect whether it is prone to deformation or wrinkles.
Usually, wrinkle resistance evaluation uses professional instruments and equipment for testing, and refers to the corresponding international standards.
In summary, the color fastness and wrinkle resistance of fabrics are important indicators for detailed evaluation of fabric quality. When actually selecting fabrics, you can refer to the relevant test reports provided by the fabric supplier or consult the relevant international standards to understand the color fastness and wrinkle resistance of the fabric.
