Natural special finishing agent
Preshade 2A
Among all natural-type auxiliaries drawing growing attention, the use of Ipposha Oil Industries' Preshade 2A, an inorganic, skin-friendly finishing agent developed in cooperation with Lion Corporation is increasing both in Japan and overseas.
Preshade 2A, made of carefully selected components of natural lamellar silicate (smectite), which is used generally in mudpack products for skin, imparts fabric water absorbency, a protective coating and smooth hand. Production of a scrooping texture in cotton is another special feature.
No adverse effects are expected in dyeing, and inhibition in water absorbency and whiteness in cotton is minimal. In addition, it also has protein-adsorbing properties.
