#1. Development of Modified Viscose Rayon Process for Low Environmental Pollution
Modified
ciscose rayon process: Carvon dioxide(CO2) is chosen
for the substitute of carbon disulfied(CS2)
Determination of suitable carbonation process: Various cellouse
carbonation process by using CO2 will be investigated.
Determination
of suitable dissolution process ; Various cellulose solution
process by using suitable solvent
(e.g. aqueous NaOH solution) will be investigated.
Determination of suitable spinning condition from
the increasing mechanical properties of regenerated cellulose
fiber.
#2. Loess dyeing by using finishing process
Improvement
of Extraction method : water extraction ¡æ ball milling method
Treatment
of some fixing agents
Pad-Dry-Curing process
#3. Viscosity Change of Ethylene-Vinyl Acetate Copolymer (EVA) / Chitosan/ Filler Emulsion
The viscosity enhancement of EVA emulsion (ethylene-vinylacetate
Copolymer) : The addition of Chitosan and Filler
(sericite, CaCO3, TiO2, Talc)
Test Methods
(1) Viscosity Measuremetn : Brookfield Viscometry
(2) Adhesion Strength : Universal Testing Machine
(3) Storage Safety Test : Conditioning in oven (50 ± 2 ¡É, 20hr)
Measurement of Viscosity Change
Application
of EVA Emulsion : Wood, Fiber, Paper, Waterproof, Cement
