Global colour and specialty chemicals company Archroma recently launched a water-based textile coating binder, Appretan® NTR, based on renewable natural resources.
After the well-reported EarthColors®, a range of dyes synthesised from materials such as almond husks or saw palmetto leaves — bio-waste from the agriculture and herbal industries — Archroma is launching another new innovation based on natural ingredients.
The new product, Appretan® NTR, a water-based textile coating binder developed for applications such as tea bags, coffee filters or capsules, uses a natural, renewable raw material that is widely available near the production site of Lamotte, France, where Appretan® NTR is produced, maintained a communiqué issued by the company.
According to Archroma, Appretan® NTR does not contain biocides or alkylphenolethoxylates (APEO) and does not release formaldehyde.
It has been designed so that the optimum properties can be achieved without additional curing step at high temperature compared to the industry standard process, thus helping to save significant energy for textile producers and the planet, maintained Archroma.
Initially developed for the chemical bonding of nonwovens for technical textiles and coating, Appretan® NTR displays excellent film-forming properties and very hydrophobic behaviour. In addition, the unique chemistry of this binder reportedly makes it resistant to water, mild solvents, oil and fat, and it also provides an increase in dry and wet tensile strength.
It may be mentioned here that headquartered in Reinach, Switzerland, Archroma is a global, diversified provider of dyes and specialty chemicals that delivers specialised performance and colour solutions in over 100 countries.
