Either of the two endothermic melting peaks found by differential thermal analysis of nylon 66 may be converted to the other by appropriate choice of annealing conditions. The two peaks are considered due to the melting of two morphological species, forms I and II. Form I is relatively fixed ...
depression of undercooling degree, LiT(cp), resulting from reduction of the equi- librium melting point reduces the driving force for the crystallization; increment of Tg(cp) associated with the presence of mixed PEI with high Tg in nylon 66 phase decreases the mobility of a crystallizable segme...
Negative spherulites and non-birefringent spherulites (the latter arising in two different temperature regions) and the so-called aggregates of nylon 66 have been reproduced and the conditions of their formation have been redefined. Growth rates were measured and the dependence on crystallization tempe...

Hence, this can be used as a complete substitute of these fibers making it from 100% Nylon Yarn, or it can also be blended with this fibers to make cheaper options for 100% cotton or 100% silk yarns.Nylon 66 has a wide range of use,...
By using low melting alloy as fusible core and nylon 66 modified by 30% glass fiber,fistula plastic parts with intricated type were prepared. 以低熔点合金为可熔型芯材料,注射成型形状复杂的30%玻纤增强尼龙66中空塑料件。 2. The technological process, principles and the key points of technology ...
This peak at around 176°C is most likely formed by the nylon 12 coated on the carbon fiber. Because of the high thermal conductivity of the carbon fiber, the nylon 12 attached to the fiber has only a thin layer. During the heating process, due to good thermal conductivity, the nylon ...
