摘要： Improved synthetic paper base material manufactured by coextrusion of a layer of polymeric material having good physical properties with one or more layers of a different polymeric material having good printability. Adhesion between the layers is increased by including in each a minor amount of an ethylenevinyl acetate copolymer.

摘要： Apparatus for achieving simultaneous, continuous, biaxial orientation of webs including means for feeding the web to clamps positioned about a pair of oppositely canted sheaves, moving the clamped web around the circumference of the sheaves, and removing the biaxially stretched web from the sheaves at a location of wider separation than the feed zone. In one embodiment the clamps are driven by rods rotating parallel to the plane of the sheaves, but about a center which is displaced from that of the sheaves to obtain nearly balanced stretch profiles. Completely balanced stretch is achieved by using slightly s-shaped rods. The clamps accelerate with the web on one semicircle and decelerate on the opposite semicircle. Acceleration provides longitudinal stretching, while the divergence of the sheave circumferences provides lateral stretching.
摘要翻译：用于实现网的同时，连续，双轴取向的装置，包括用于将幅材馈送到位于围绕一对相对倾斜的滑轮定位的夹具的装置，将夹紧的幅材移动到围绕滑轮的圆周的位置，以及在一个位置比进料区更宽的分离。在一个实施例中，夹具由平行于滑轮的平面旋转的杆驱动，但是围绕与滑轮的中心相移的中心，以获得几乎平衡的拉伸轮廓。通过使用略微s状的棒实现完全平衡的拉伸。夹具在一个半圆上与网加速，并在相对的半圆上减速。加速度提供纵向拉伸，而滑轮周长的发散提供横向拉伸。

摘要： POLYURETHANE FOAMS ARE RENDERED HYDROPHILIC BY COATING A ANHYDRIDE CONTAINING POLYMER ONTO THE FOAM AND THEREAFTER REACTING AT LEAST A PORTION OF THE ANHYDRIDE GROUPS WITH AMMONIA OR A PRIMARY OR SECONDARY AMINE. THER PERMANENCE OF THE FOAMS HYDROPHILLIC CHARACTER CAN BE ENCHNACED BY CROSSLINKING THE ANHYDRIDE COATED FOAM WITH A POLYFUNCTIONAL AMINE.

摘要： Apparatus for producing a randomly mixed fibrous web of high strength and opacity. A thermoplastic polymer is extruded through a die having slots of varying length and cross-sectional area. Air at about the polymer melt temperature is impinged angularly on the fibers and allowed to expand thus cooling the fibers and breaking them up into varying dimensions as they are deposited on a carrier. In a preferred embodiment a controlled Coanda effect is applied so as to provide an overall wavy pattern of randomly mixed fibers.
