DyStar launches PCA free Levafix ECO Black dye
Apr '15
Specialty textile dyes marketer DyStar has launched Levafix ECO Black which it said is completely free of p-chloroaniline (PCA) and other regulatory-controlled amines and is an advanced novelty in the industry.

“As it is based on new chemistry it is free of PCA and does not contain any of the commonly used commodity reactive black dyes,” DyStar said in press release.

“This new dye is compliant with all Restricted Substance Lists (RSL) and with Oeko-Tex Standard 100 and is also free of heavy metals,” it added.

Levafix ECO Black is a neutral black shade with a superior level of colour constancy between daylight and artificial light sources.

“Due to its novel chemistry, higher wet and light fastness properties can be achieved compared to conventional reactive black dyes,” DyStar explained.

Its properties include, very good fastness to simulated multiple wash like ISO 105 C09, AATCC190, M&S C10A leading to reduced wash-down and shade change problems for end-users.

It also added that the ISO 105 C06 C2S or 60°C with perborate wash fastness is superior to conventional reactive black types.

Additionally, Levafix ECO Black also gives excellent results in the demanding adidas wash fastness test at 40°C.

“The fastness profile is completed by good results in the chlorinated water fastness test like ISO 105 E03 - 20 ppm active chlorine,” it noted.

DyStar also said that there is a low or on-tone staining of adjacent fibres in the dye-bath so there is no brown staining of polyamide, unlike many reactive black dyes.

These superior oxidative wash and light fastness properties lead to a more sustainable textile end-product due to better retention of the original shade.

According to DyStar, with this novelty, it provides another innovation to the textile industry to achieve best quality with minimal environmental impact.

DyStar added that it will continue to develop further Levafix dyes with similar outstanding ECO and performance properties in coming months to offer a complete range to its customers.

DyStar Group is a solution provider, offering customers across the globe a complete range of colorants, auxiliaries and services.

The DyStar Group has offices, competence centers, agencies and production plants in over 50 countries to ensure the availability of expertise in all important markets.

With a heritage of more than a century of innovation for the textile and leather industry, DyStar has developed into new markets and now serves the paper, plastic and many other specialty chemical industries. (AR)
