Green PE laminated viscose has gained significant popularity in various industries due to its unique combination of properties. As a supplier of this innovative material, I often encounter questions from customers regarding its durability, especially when it comes to colorfastness after washing. In this blog post, I will delve into the factors that affect the fading of green PE laminated viscose and provide insights based on scientific understanding and practical experience.
Understanding Green PE Laminated Viscose
Before discussing the fading issue, it's essential to understand what green PE laminated viscose is. Viscose, also known as rayon, is a semi - synthetic fiber made from cellulose, typically derived from wood pulp. It is known for its softness, breathability, and absorbency, similar to natural fibers like cotton. On the other hand, polyethylene (PE) is a thermoplastic polymer widely used in various applications due to its low cost, flexibility, and chemical resistance.
In green PE laminated viscose, a thin layer of PE film is laminated onto the viscose fabric. This lamination process enhances the fabric's properties, such as water resistance, tear strength, and durability. The "green" aspect usually refers to the use of environmentally - friendly manufacturing processes or materials, which is an increasingly important consideration in today's market.
Factors Affecting Fading
1. Dye Quality
The quality of the dye used to color the viscose fabric plays a crucial role in determining its colorfastness. High - quality dyes are formulated to have strong chemical bonds with the fiber molecules, which makes them more resistant to fading during washing. In contrast, low - quality dyes may not adhere well to the fibers, leading to color loss when exposed to water, detergents, and mechanical agitation.
As a responsible supplier, we ensure that we use high - quality dyes in our green PE laminated viscose products. These dyes are tested for their colorfastness according to international standards, such as the ISO 105 series of tests, which evaluate the fabric's resistance to various fading agents, including washing, light, and perspiration.
2. Washing Conditions
The way the green PE laminated viscose is washed can significantly impact its color retention. Harsh washing conditions, such as high - temperature water, strong detergents, and excessive agitation, can break the chemical bonds between the dye and the fiber, causing the color to fade.
For example, using hot water above 40°C (104°F) can accelerate the fading process, as heat can weaken the dye - fiber bonds. Similarly, detergents containing bleach or strong chemicals can also damage the dye molecules. To maintain the color of green PE laminated viscose, it is recommended to wash it in cold or lukewarm water (below 30°C or 86°F) using a mild, non - bleaching detergent. Gentle agitation or a delicate cycle on the washing machine can also help reduce the risk of fading.
3. Lamination Process
The lamination of the PE film onto the viscose fabric can also affect colorfastness. If the lamination process is not carried out properly, it may cause stress on the fabric, which can lead to damage to the dye - fiber bonds. Additionally, the type of adhesive used in the lamination process can interact with the dye, potentially causing color changes or fading.
At our company, we have developed a precise lamination process that minimizes stress on the fabric and ensures a strong bond between the PE film and the viscose. We use high - quality adhesives that are compatible with the dye and the fabric, reducing the risk of color - related issues.
Testing and Results
To provide our customers with reliable information about the colorfastness of our green PE laminated viscose, we conduct extensive testing. We perform wash tests using different washing conditions, including various water temperatures, detergent types, and agitation levels. After each wash cycle, we evaluate the color change of the fabric using a colorimeter, which measures the color difference (ΔE) between the original and washed samples.
Our test results show that when green PE laminated viscose is washed under recommended conditions (cold water, mild detergent, gentle agitation), the color change is minimal. In most cases, the ΔE value is below 1, which is considered an acceptable level of color change according to industry standards.
Comparing with Similar Products
Let's compare green PE laminated viscose with other related products in terms of colorfastness. For instance, PE Laminated Non Woven Fabric 140gX1.02m is a popular non - woven alternative. Non - woven fabrics are generally more prone to color fading compared to woven fabrics like viscose, as the fibers in non - woven fabrics are not as tightly bound together.
Another product is Blue PE Laminated Viscose. The color blue may have different fading characteristics compared to green, depending on the specific dye used. However, our testing methods ensure that both green and blue PE laminated viscose products meet high colorfastness standards.
Pe Film Laminated Nonwoven Fabric is also in the same product category. While non - woven fabrics offer certain advantages, such as lower cost and higher production speed, our green PE laminated viscose provides better colorfastness and a more natural feel due to the use of viscose fiber.
Conclusion
In conclusion, green PE laminated viscose does not fade significantly after washing when proper care is taken. The key factors influencing colorfastness are dye quality, washing conditions, and the lamination process. By using high - quality dyes, following recommended washing instructions, and implementing a precise lamination process, we can ensure that our green PE laminated viscose products maintain their color vibrancy even after multiple washes.
