【摘要】 现代造纸业不断地向宽幅、高车速、高线压方向发展，要求造纸毛毯必须具有耐高压、滤水好、弹性高、使用寿命长等特点，复合造纸毛毯以其优异的性能成为符合现代造纸业发展的最佳选择。目前，国内造纸毛毯行业在科研上投入的非常少，产品的检测手段和设备还不完善。受造纸行业的局限，国内造纸毛毯比国际先进水平落后了20年左右。对复合造纸毛毯的研究非常有限。本课题从一下几个方面对复合造纸毛毯进行了研究。(1)研究材料的性能特点，选择最适当的原材料以及原材料的各种指标。(2)对复合造纸毛毯的成型工艺(包括经纱、纬纱、组织结构、纤网部分和针刺部分等)和后整理工艺(包括化学整理和热定型)等过程中所涉及的各个工艺参数进行分析研究，形成完整的工艺系统。(3)选定底网组织、针刺深度和纬纱粗细三个对复合造纸毛毯有着重要影响的因素进行了正交实验，设计了9种不同的复合造纸毛毯。对其压缩回弹性、透气性和透水性等7项指标进行了测试，在分析的基础上，得出了各因素水平对各指标的影响趋势，并最终得出了造纸毛毯性能的优劣排序及最优工艺条件。论文所形成的完整的工艺体系可以为实际生产提供技术参考，对复合造纸毛毯的正交实验及结果分析可以为复合造纸毛毯企业的产品开发、技术改进提供理论依据和参考。更多还原

【Abstract】 The modern papermaking industry is developing with the characteristics of largewidth, high speed and pressure, that requires the paper-making felt bear high pressure, hasthe good drainage, elasticity and a long life and so on. The composite papermaking feltbecomes the best choice that accord with the development of the papermaking industrybecause of its outstanding property. Now domestic papermaking felt industry pays little toscientific research and doesn’t have sufficient testing methods of product and equipment.Confined by the papermaking industry, domestic papermaking felt is dropped behind bythe international advanced felt for about 20 years. The research on the compositepapermaking felt is very limit. This subject does some research on the compositepapermaking felt in the following aspects.(1) Studying on the property of the material and choose the best material and thefittest index.(2) Studying on the involved techniques parameters of the forming techniquesincluding warp, weft, the weave of backing fabric, fiber net and needle-punching sectionand the after-finishing techniques including chemical finishing and heat setting to formthe integrated technical system.(3) The weave of backing fabric, the needle-punching depth and weft count of thepaper making felt are chosen as the factors that influence the property of the papermakingfelt at a great deal in the orthogonal test and 9 deficient kinds of composite papermakingfelt are made. Then 7 kinds indexes such as the compression resilience, the gaspermeability and the osmosis of the paper making felt and so on are tested and the orderof the property of the papermaking felt from the best to the worst as well as therelationship between the processing parameters and properties of the paper making felthas gained on the basis of the analysis. And the optimum technique has gained.The integrated technical system formed in this paper can provide reference forpractical production. The orthogonal test and its analysis can provide theoretical basis andreference for the product development and technical promotion of the compositionpapermaking felt enterprises.更多还原
