The invention also provides a nonwoven cloth of drawn long fiber provided with a first web layer of crimped filaments, and a second web layer of substantially non-crimped, drawn long fiber filaments, and comprising different kinds of polymers of high strength and bulkiness, and a method of ...
aI enjoy reading different kinds of books, but "Harry Porter" is my favorite one. The story is very long but I am interested in it. Harry was such a brave and clever boy that he dared to fight against powerful enemies. His Z-shaped scar and magic stick brought me into a magical worl...
aPolymers can be classified in several different ways:according to their structures,the types of reactions by which they are prepared, their physical properties,or their technological uses. 聚合物可以被分类用几别的方法:根据他们的结构、他们准备反应的种类,他们的有形资产,或者他们的技术用途。[translate...
fat substitute is an effective way to address the worldwide obesity problem in food industry. Different kinds of compounds have been developed and applied as fat substitute. Gelatin-carrageenan mixture with enzymatic and ionic crossing linkage is a potential fat substitute due to a possible fine tex...
Microfiber and microsuede are synthetic fabrics made of polyester and polyamide or polyester and nylon, which themselves are plastic polymers derived from petroleum. Microfiber is often used for cleaning cloths to trap dust and dirt and athletic wear to wick away moisture from your skin. Microsuede...
Quality Magnetic Material Basic research and development is crucial to the development of materials. Therefore, in addition to bonded magnetic compounds, we also have related studies on the development and preparation of powders, the synthesis and modification of polymers. We believe that only continuou...
The different shear levels were imposed on three kinds of polymers, isotactic polypropylene, polystyrene, and polyurethane, that have different properties. In contrast to the dies with diameters of 0.5, 0.7, and 1mm, with the increasing shear rate the growth of the logarithmic shear stress ...
With respect to a batchwise polymerization in first agitation type polymerizer vessels 3A and 3B and the alternate feedings of prepolymers 4A and 4B from polymerizers 3A and 3B to second agitation type polymerizer vessel 3C, the same operation as mentioned above was repeated, so that the prep...
The results showed that Fedors equation was the most accurate equation to describe the dilute solution properties of these kinds of polymers. The lower value of the polymer concentration parameter (C_m) in Fedors equation was corresponded to the higher value of the constant k in Schulz-Blaschke...
Many modern pedestrian-only bridges are made out of modern material, while some tourist pedestrian bridges feature more exoteric designs that even include transparent polymers in the decking, enabling users unrestricted view to the area below the bridge. While the majority of modern pedestrian bridges...
