What Is Color Fastness
As a professional sock manufacturer, we are well aware of your concern about product quality. Among them, “color fastness” is one of the main evaluating indicators of socks quality. In this article, we will explain this concept in detail and introduce how we guarantee the long-lasting color stability from the production side.
Key Factors Affecting Color Fastness in Socks
The durability of color is no random chance; it can be attributed to the following three main components:
Material factors
Different fibers have different affinities for dyes and bonding mechanisms. For instance, cotton fibers show hygroscopic absorption, which facilitates the penetration of dye, but the fibers also lose color by washing; The difference is that the polyester fibers are much more compressed, so the polyester holds the dye much more tightly. Therefore, it is important to consider the material type for employing a suitable dyeing method and the appropriate dye.
Dyeing technology
We utilize advanced high-temperature, high-pressure dyeing process. The mechanism is that using certain process conditions dye molecules deeply penetrate into fiber interior and react with components inside fiber followed by forming stable complex one after another giving the ability of color fixation much higher than one attained from traditional processes.
Chemical substances and softeners
The choice of chemical additives in the post-treatment process is extremely significant. The addition of the wrong softeners, or the use of harsh chemicals, can break down the bonding between the fibers and the dye and cause it to fade. We have opted for sustainable additives with only the slightest effect on color fastness, yet which also provide enhanced wearing comfort and ensure the colors stay as vibrant for as long as possible.
How We Ensure Color Fastness as Your Manufacturer
In order to ensure that the product leaving the factory can meet the high standard, we have made a tough quality inspection:
Washing fastness test: With professional test equipment, we simulate various household washing methods to test the color change of samples before and after washing, and the products meet the national standards.
Color fastness to friction test: color fading on dry and wet socks is quantitatively tested by an instrument under friction conditions, so as to avoid the problem of color loss caused by daily wear and friction.
Stain resistance color fastness test: Simulate the environment of human sweat to check whether the color is stable under acidic and alkaline environment, which can be used in real life.
It was with the help of these critical tests system that we could impartially test the color fastness of every batch of our products.
Educating the End-Consumer: Proper Garment Care
To protect the excellent quality of the sock to the greatest extent, consumer has advised to use as following:
Turn and wash: To reduce surface abrasion is recommended that socks are turned inside out before washing.
Cold gentle wash: Warm or cold water below 30℃ (warm or cold), gentle cycle is recommended.
Use neutral detergent: Do not use strong detergents with chlorine bleach ingredient.
Dry in a ventilated and cool place: After washing, please dry it as soon as possible. Do not expose to the sun for long time!
