我国古代织物用金之表现技艺发展的三个阶段

试将我国古代织物用金之表现技艺的发展，整体分为三个大的阶段。第一阶段是隋唐之前的装饰点缀阶段，第二阶段是隋唐至宋的表现转折阶段，第三阶段是元明清初期的繁荣发展阶段。在我国古代织物用金之表现技艺的发展过程中，中西纺织技术的交流，发挥了至关重要的推动作用。对西域织金技艺的消化吸收，则是改变我国古代织物用金之表现技艺的重要一环。

等离子体处理对非织造布表面润湿性的效应

通过用等离子体处理非织造布的方法来提高其表面润湿性。电晕放电和低压辉光放电都对丙纶非织造布表面的润湿性有改善,低压辉光放电不涤纶非织造布表面的润湿性有改善。电晕放电处理非织造布的表面改性效果及改善维持时间都不如低压辉光放电。用等离子体处理非织造布来改善其表面润湿性的效果不能维持很长时间。等离子体处理可减小丙纶、涤纶非织造布表面与水的接触角,从而提高其表面的再润湿性。

Turbulent Flow Action of Pulp in Wet - Laid Non - Woven Processes

The paper deals with the fluid field of web forming in wet-laid non-woven production.The influence of the turbulent flow on blending fiber and occluded fluid produced in pulp flow has been discussed in theory and practice.The suitable use of the imported velocity of pulp is very important in producing wet-laid products of good quality.     

Study on Bending of Woven Fabrics Using Linear Viscoelasticity Theory

The bending behavior of woven fabrics under low curva-ture conditions has been analyzed by linear viscoelastictheory.The fabric is assumed to behave viscoelasticallyand to be subjected to frictional restraints in bending de-formation.The frictional restraint is considered to beproportional to the curvature and can be described by africtional moment.A model has been constructed by astandard three-element solid model and a paralleledfrictional sliding element.The equations of the model fora cyclic curvature variation are derived.A set of param-eters of the equations for each fabric has been obtainedexperimentally.Predictions of the bending rigidity andhysteresis for wool,cashmere,wool/polyester blended,polyester and cotton fabrics are made,displaying verygood agreement with the experimental observations.

Wet Transfer Model of Woven Fabric

To investigate wet permeability of woven fabric, a wet transfer model of woven fabric is built up and by means of the model, the main factors which have significant influences on its wet permeability function, including liquid/ material contact angle, fiber diameter, fiber cross-section configuration, the number of fibers, yarn＇s twisting angle and woven density, are discussed. Finally it is derived from the argument that optimal design of wet transfer function of woven fabric can be obtained.     

Filling Simulation of Three-dimension Braided Composite in Resin Transfer Molding

This paper measured permeability of three-dimension braided preform by radial technology. The results show that principal permeability tensor coincided with their braiding axial direction. The software of one dimensional flow filling mold was designed using Visual C ＋ ＋ language. Filling time is predicted and validated. The result showed that the filling time of the mold centerline agrees with the prediction value. The filling time of the mould edge is shorter than that of the prediction. An actual plate of 3 - D braided preform / modified polyarylacetylene composite is produced according to prediction value and validation analysis.
