How to protect the color brightness of PP spunbond nonwoven fabric?

There are several measures to protect the color brightness of PP spunbond nonwoven fabric .

Choosing high-quality raw materials

Raw materials are one of the key factors affecting the brightness of product colors. High quality raw materials have good color fastness and antioxidant properties, which can effectively prevent pigment fading during manufacturing and use. Therefore, when making non-woven fabric products, it is advisable to choose raw materials with higher quality as much as possible.

Strengthening dye fixation

PP spunbond non-woven fabric products need to strengthen dye fixation during the dyeing process to enhance color persistence. This can be achieved by increasing the binding force between dyes and fibers. One way is to use special dyes and perform pre-treatment treatments such as pre soaking and pre dyeing while dyeing. Another way is to use fixatives or dyes to prevent the loss of dye during use.

Reasonable selection of dyeing process

Dyeing process is an important factor in determining the brightness of non-woven fabric colors. A reasonable dyeing process can avoid color fading and lightening. During the dyeing process, the appropriate dyeing temperature, time, and additives should be selected based on the characteristics and requirements of the non-woven fabric.

Conducting color fastness testing

Conducting color fastness testing can test the color fastness and stability of PP spunbond non-woven fabric products. Through testing, we can understand whether the color of the product after dyeing is bright, and make improvements and adjustments based on the test results. Color fastness testing includes washing fastness testing, rubbing fastness testing, light fastness testing, etc.

Proper use and storage

When using and storing spunbond non-woven fabric products, they should be handled and decorated correctly to avoid color fading or fading due to improper use. For example, avoid prolonged exposure to sunlight, avoid contact with strong acidic and alkaline substances, and avoid prolonged friction with hard objects. In addition, non-woven fabric products should be stored in a ventilated and dry environment, away from moisture and high temperatures, to extend the product’s service life and enhance its color brightness.

 Regular cleaning and maintenance

For spunbond non-woven fabric products, regular cleaning and maintenance are important measures to protect the brightness of colors. When cleaning, it is advisable to choose mild detergents and methods, avoid using strongly alkaline or bleach containing detergents, and avoid prolonged soaking or rubbing. After cleaning, it should be dried as soon as possible to avoid prolonged exposure to sunlight or strong light.

Conclusion

In summary, protecting the color brightness of spunbond non-woven fabric products requires starting from the selection of raw materials, dyeing processes, fixing dyes, color fastness testing, correct use and storage, regular cleaning and maintenance, and other aspects. Only by comprehensively considering these measures and adopting corresponding methods and means to protect and maintain them, can the color brightness of spunbond non-woven fabric products be maintained and extended to a certain extent.
