| Summary: | 博士 === 國立中興大學 === 森林學系 === 86 === Since users'' preference for measuring the surface softness of
creped tissue papers by handfeel method which is not considered
an objective and reliable way. Two new methods for measuring
the surface softness of tissue paper were examined in this
study.
One of them, dubbed CK method to determine the surface
softness of embossed or creped tissue papers by testing the
adhesion between the glued area of paper specimen and removable
self-stick label paper. The testing results of this new method
were compared favorably with those of artificial finger tip
method and the subjective handfeel method. The CK method is a
simple method to measure paper surface softness. Some problems
involved in the practical application of this method are also
discussed. Practicall
The other method dubbed sled method. This method uses a sled
which bottom is fabricated with a special rubber mass driven by
motor to apply a horizontal force (simulating the movement of
finger tip over the specimen) on the surface of test paper at
fixed speed. The sliding force (gf) is measured and regarded as
an indication of the surface softness of the test specimen. The
sled test results of commonly used embossed tissue papers in
Taiwan suggest that the sled method provides good correlation
with the h
A sled method is proposed to accurately assess the changes in
softness on both sides of various embossed tissue papers. The
method offers a means of controlling and improving quality of
tissue paper for mill operators.
Softness, absorbency and compressive resistance are the
attributes of perceptions associated with "textile materials"
and properties that make tissue paper different from other
types of papers. Creping is a vital process that embodies these
characteristics to tissue paper. Selecting the optimal creping
conditions become the most important task in the manufacturing
of tissue paper. The pressure of the touch roll, creping ratio
and conditions of the creping blade are important factors
affecting creping of t
By adding 2 % of cationic calcium carbonate in stock , it not
only improved the surface softness of creped tissue paper
measured with sled method but reduced the COD in effluents.
