Natural Care Finish (AH-30, AGN)

Textile processing agent for hygroscopic warming property

PARAFINE AH-30

PARAFINE AH-30 is liquid compound of special polycarboxylic acid. By applying with CATALYST AQH for polyester　or their blended cloth, PARAFINE AH-30 gives hygroscopic warming property with good durability.
Polyester cloth treated by PARAFINE AH-30 has a temperature about 1.5｡C higher than untreated polyester cloth when absorbing moisture.PARAFINE AH-30 is applicable by pad-dry process.

Examples of test result

Specimen：	polyester jersey
Conditions ：	15 % soln. PARAFINE AH-30 + 2 % soln. CATALYST AQH Pickup 100% dipping → nipping → drying (110℃ x 2 min.) → curing (160℃ x 1 min.) → treatment with a lye ((60℃ x 20 min. in 1 g/liter sodium carbonate solution) → rinsing
Test ：	Hygroscopic warming performance A thermometer was wrapped with specimen, and left in a thermo-hygrostat at 20℃ and 40% RH until the temperature was stabilized. The humidity was Increased up to 90%, and rise of temperature of specimen was determined.

Antimicrobial agent of colloidal silver nanoparticles
PARAFINE AGN

PARAFINE AGN is a unique antimicrobial agent with fabric softening properties newly developed by using the latest technique for supporting (reacting) nano-sized particles of colloidal silver by silk amino acid.
PARAFINE AGN comprises colloidal silver nanoparticles (3 ~ 5 nm) that offers superior antimicrobial effect, and silk amino acid to give softness and skin friendliness. Colloidal silver supported by silk amino acid exhibits good washing resistance even though it is applied in concentration as low as no silver color appear.
