The prouct quantities of polyester fiber in Tiwan is the
chamption in theworld right now , but there are lots of
countries constructing new factoriesmaterials of non-woven ,
the intension of this experiment is try to use theworld right
now , but there are lots of countries constructing new
factoriesorigional equipments and produce low melting point
copolyester in fiber gradefor the use of non-woven. We
hope to make the copolyester products have different
applications and raise the ability of competition in the
industry ,and benefit from the improvement. The experiment is
based on the design of mixture experiment. We design two
sets of experiments, both using TPA as the major materials. For
A part is using IPA and AA as the minor material ; for Bpart is
using IPA and SA. We try to discuss the relationship between the
ratioof minor row materials to the quantities of copolyester.
From this experiment,we have the conclusions that :1. The Tg of
copolyester is lower as adding moreAA or SA. 2.IPA、AA or SA all
obiviously make the melting point of copolyester lower. 3. In
the range of contour line , we can predict the ratio of
materials to the change of copolyester melting point from the
first order polynominalcontour plots. In the real applications,
we can alter the ratio of material in the same contour line and
produce products of different Tg.
