Blend dispersed

Wool—Polyester Fibers. The 45/55 wool—polyester blend is the most common fiber combination in the worsted industry. Strength and exceUent dimensional stabiHty of the polyester fiber enable the creation of lightweight wear fabrics not obtainable before. Economy has modified the fiber ratio and 30/70 and 20/80 wool—polyester blends are as common as the classical 45/55 blend. Disperse dyes for polyester and acid or neutral premetaUized dyes for wool are employed in a one-bath process. Should cationic dyes be used for the wool portion, a one-bath procedure can only be employed for light to medium shades, whereas dark shades require a one-bath two-step process. Wool blends should not be dyed above 105°C in order to avoid deterioration of the fiber quaHty. 

Polyester Fiber Blends. Disperse dyeable and cationic dyeable polyester fibers are frequentiy combiaed ia apparel fabrics for styling purposes. Whereas the disperse dyes dye both fibers, but ia differeat depths, selected cationic dyes reserve the disperse dyeable fiber completely, resulting ia color/white effects.

The polymer-blend dispersions of PTFE and fluorinated-pitch with various concentration of fluorinated-pitch have been coated on stainless steel (SUS-304). The various coated polymer-blend were heat-treated at 350 °C 5 °C for 30 minutes. Further, samples were subjected to EB irradiation with a 200keV from EB accelerator (CURETRON , NHV Corporation) up to 1000 kGy at 330 °C 3 °C in nitrogen gas atmosphere. 

For mechanical test such as tensile test and flexural test, the impregnation of polymer-blend to the carbon fiber was carried out several soakings of the fiber in the polymer-blend dispersion consists of PTFE (98.2 wt%) and fluorinated-pitch (1.8 wt%). A sheet of chemical crosslinked pre-forming sample was prepared under the pressure at around 20 MPa and then heat-treated at 350 °C 5 °C for 30 minutes. Samples were irradiated by EB up to 1000 kGy at 335 °C 3 °C in nitrogen gas atmosphere.

Molecular characteristics of syrrthetic polymers are never uniform. They always exhibit certain dispersity. Dispersity is a new term, coined by lUPAC, which should substitute the former term distribution. In fact all synthetic polymers represent mirlticomponent mixtures of macromolecirles, which differ in one or several molecular characteristics. With a rather few exceptions such as for example some polymer mixtures and polymer blends, dispersities in molecular characteristics of common polymers are continuous in nature. For example, the molar masses of macromolecules that form particular members of typical homologous series usually differ only in the molar mass of a single monomeric rmit The resulting total molar mass of polymers ranges from a minimirm, to a maximum value, while the latter may be several times higher than the minimum value. Therefore, the molecular characteristics are described with their average values or with the dispersity functions. Consequently, we have ... 

In these blends, dispersion of the two phases is most often achieved by intensive mechanical mixing, but in the polypropylene-EPR combinations, polymerizing the finely dispensed elastomer phase simultaneously with the hard polypropylene is possible [13-15].
