DYEING OF POLYESTER, ARAMID AND POLYPROPYLENE FIBERS IN SUPERCRITICAL CO2
Abstract:
Polyethylene terephthalate (PET) and polytrimethylene terephthalate (PTT) fibers as well as difficult-to-dye fibers such as aramid and polypropylene were dyed using supercritical carbon dioxide at pressures between 10 ~ 33 MPa and temperatures between 35 ~ 150 degrees Celsius. Special co-solvents were employed to promote the dye sorption. The equilibrium sorption of dye increased with pressure or density as well as temperature. Dye-sorption was analyzed with a sorption model. Colors other than the three primary colors were obtained by using various amounts of dye mixtures with different dye ratios. The optimum amount of cosolvent was also investigated. These sorption data will provide a basis for replacing the current
dyeing process with the supercritical fluid dyeing process that does not yield any pollution problem but allows us to save a large amount of energy. Furthermore, the sorption model may reduce the required number of experiments considerably, leading to a low initial investment cost for the new dyeing process.

A New, Durable Antimicrobial Finish for Textiles
Abstract:
AEM 5700 Antimicrobial (3-trimethoxysilylpropyldimethyloctadecyl
ammonium
chloride)+ imparts a durable, antimicrobial finish
to textiles. The finish protects the fabric against
bacteria and fungi, which cause deterioration. It
also inhibits the growth of odor-causing bacteria in
in vitro tests. In vivo organoleptic tests confirm the
practicality of this concept under actual use
conditions on socks.

STATISTICAL ANALYSIS OF HAIRINNES OF YARNS PRODUCED
ON DIFFERENT SPINNING SYSTEMS
Abstract:
Hairiness can be considered as sum of the fibre ends and loops standing out from the main
compact yarn body. Beside other instruments, there are two major testing equipments
available on the market used for evaluating the yarn hairiness. The most popular instrument
is the Uster hairiness system, which characterizes the hairiness by H value, and is defined as
the total length of all hairs within one centimeter of yarn. The hairiness H is an average value
giving no indication of the distribution of the length of hairs. The so-called hairiness diagram
contains information about the H valued in the 400 m yarn portion. Main aim of this
contribution is analysing the distribution of H value for cotton yarns and comparing the
compact yarns according to possible bimodality (two types of hairiness). The results show
that in general the fibres hair distribution are of bi-modal shape and comprises a mixture
Gausian distribution.
