Non-woven masterbatch: Put on colorful "coat" for non-woven fabric!

In the production process of non-woven fabrics, non-woven masterbatches play an indispensable role, giving non-woven fabrics colorful colors and diverse functions. Today, let's take a closer look at the non-woven masterbatch.

First, uncover the mystery of Non-woven masterbatch

Non-woven masterbatch is a kind of aggregate which is made by uniform loading of super constant pigment or dye in resin. In short, it is a key material for coloring and adding special properties to non-woven fabrics. At the time of production, only the color masterbatch and the basic raw materials of the non-woven fabric are mixed in a certain proportion, and the non-woven fabric can show the required color after processing.

Second, the composition and characteristics of Non-woven masterbatch

component

Pigment or dye: This is the core component that determines the color of non-woven fabrics. Organic pigments have bright color and strong coloring power. Inorganic pigments have good light resistance and heat resistance. For example, organic pigments such as phthalocyanine blue are often used to create bright blue tones of non-woven fabrics; Inorganic pigments such as iron oxide red can give non-woven fabrics a stable red color and maintain color in a high temperature environment.

Carrier resin: as a pigment or dye carrier, it should have good compatibility with non-woven raw materials. Common carrier resins are polypropylene (PP), polyethylene (PE), etc., such as in the production of polypropylene non-woven fabrics, the color masterbatch of PP carrier is very commonly used to ensure that the color masterbatch is evenly dispersed in the raw material.

Dispersant: helps the pigment or dye disperse evenly in the carrier resin to avoid agglomeration. Like stearate dispersants, they can reduce the surface tension between pigment particles, making them better "home" in the carrier resin.

Characteristic advantage

High coloring power: Only a small amount of masterbatch can stain a large number of non-woven fabrics with rich color, saving cost and significant color effect.

Good dispersion: advanced production process and high-quality additives, so that the pigment is fully dispersed in the carrier, to ensure that the color of non-woven fabric is uniform, no color spots, color bars and other problems.

Strong stability: excellent weather resistance, chemical resistance and heat resistance. Non-woven fabric used outdoors, after a long time of sun and rain, the color is still lasting; In industrial non-woven fabrics exposed to chemical substances, they will not fade easily.

Third, the application field of Non-woven masterbatch

Packaging field: In the non-woven packaging of food and daily necessities, the color masterbatch gives the packaging a unique appearance and attracts the attention of consumers. Such as colorful gift packaging non-woven fabrics, colorful, enhance product quality.

Medical and health fields: medical nonwovens usually need specific colors to distinguish uses. The blue surgical towel non-woven fabric is colored by the color masterbatch, and the color masterbatch should meet strict standards such as health and non-toxicity.

Home decoration field: for the production of sofa covers, curtains and other non-woven fabrics, color masterbatch provides rich color choices to meet the needs of different home styles. Such as the pastoral style of floral curtain non-woven fabric, by the color masterbatch to show a fresh color.

Agricultural field: agricultural film, sunshade net and other non-woven products, color masterbatch not only color, but also add anti-ultraviolet and other functional additives. Black agricultural film non-woven fabric, can effectively inhibit the growth of weeds, while playing a role in insulation and moisturizing.

Four, how to choose the right Non-woven masterbatch

According to the non-woven material selection: different materials of non-woven fabrics need to match the color masterbatch of the corresponding carrier resin, PP non-woven fabrics choose PP carrier color masterbatch to ensure compatibility.

Consider the color needs: determine the color fastness, brightness and other requirements of the desired color. Such as outdoor non-woven fabrics, to choose good light resistance masterbatch to ensure lasting color.

Focus on product quality: Check the test report of the masterbatch to ensure that it meets environmental protection, health and other standards, especially for products used in food and medical fields.

Although the color masterbatch of non-woven fabrics is small, it plays a key role in the beauty and function of non-woven fabrics. With the development of technology, I believe it will bring more wonderful for the non-woven industry.
