摘要:
An apparatus for forming a polycomponent fibre having a first, fibre forming component comprising a polymer, and a second, component comprising an active ingredient that will selectively reduce or remove components of tobacco smoke. The apparatus has a first reservoir for containing the first component, and a second reservoir for containing the dispersion, second solution or liquid. The dispersion, second solution or liquid includes the second component. The apparatus also has a polycomponent spinnerette adapted to coextrude the first component and the second component to form the polycomponent fibre. The apparatus also includes a first conduit for connecting the first reservoir to the spinnerette, and a second conduit for connecting the second reservoir to the spinnerette.
摘要:
An improved extrudable solution such as a cellulose acetate/acetone spinning solution is provided containing cellulose ester, solvent, metal oxide precursor, acid, and water. The solution is extruded such as by spinning and produces a shaped article such as a cellulose acetate fiber containing metal oxide interpenetrating networks.

CELLULOSE ACETATE FILAMENTS HAVING EXCELLENT RESISTANCE TO HYDROTHERMAL DELUSTERING IN HOT WATER OF 110*C. AND ABOVE, GOOD QUALITATIVE REPRODUCIBILITY AND PRACTICALLY SATISFACTORY FIBER STRENGTH, AND PROCESS FOR PRODUCING SUCH FILAMENTS BY USING CELLULOSE ACETATE FLAKES WHICH HAVE BEEN POST-TREATED UNTIL THEIR REFINED PARAMETER AT THE STABILITY OF 0.08% IS REDUCED TO NO HIGHER THAN 80.
