With the development of science and technology, the growing shortage of chemical fiberdevelopment of mineral and petroleum resources has been greatly restricted, the development ofnatural fibers have a broad space for development. Natural fibers have unique natural propertiesand characteristics: breathable, moisture excellent thermal performance, comfort, etc., in addition,some products have a very good health effects. Natural green ecological products are increasinglyfavored by the majority of customers. PMFT cane fiber is one of them.But PMFT vine previous study development process, there are still many problems, thetraditional degumming process cumbersome and complex, time-consuming, energy-consuming,high costs, and because of its single fiber length short, spinning poor, difficult to achieve SpinningWeaving requirements, therefore, half degumming degumming inevitable. This paper uses analkali-oxygen bath short process degumming process, focusing on process parameters studied, inorder to achieve an effective half unglued effect. Meanwhile, researchers at the half degummingprocess parameters, the performance of different degumming process technology resulting fibers,provide the basis for the subsequent series of product development.The main contents and conclusions are as follows:(1) PMFT vine debarking process improvements exploration and research: to PMFT vine dry,wet stripping process, while the dry, wet stripping resulting bast quantitative analysis of thechemical composition, chemical composition and other common natural fiber materials contrastanalysis to determine the base flow of oxygen-bath unglued short program.(2) Study rattan phloem half degumming PMFT: unglued according to a predetermined plan,implement degumming single factor experiments, the effects of each single factor on residual gumcontent and residual lignin. Under this condition, the determination may be spinning residual gumcontent index8.21%±1.00%range of process parameters: alkali concentration7~9g/L, scouringtemperature80~90?, scouring time70~90min, hydrogen peroxide concentration of10~30ml/L,and the orthogonal experiment, to explore the factors of degumming compare the degree ofinfluence the size of the data processing by fuzzy math to determine the optimum processindicators can be spun nearly as NaOH concentration8g/L, H2O210ml/L, scouring temperature85?, scouring time90min; residual gum rate of8.28%, the residual lignin content of6.42%; Apreferred process for the NaOH concentration of8g/L, H2O230ml/L, scouring temperature80?,scouring time80min, residual glue rate of7.97%,6.09%residual lignin content; B preferredprocess for the NaOH concentration9g/L, H2O220ml/L, scouring temperature80?, scouringtime90min, residual gum content7.78%,6.18%residual lignin content; Process C preferredconcentration of NaOH7g/L, H2O220ml/L, scouring temperature85?, scouring time80min,residual gum content9.06%,6.33%residual lignin content.(3) study the performance of vines dry fiber stripping process PMFT: in the orthogonalexperimental conditions parameters to study the effect of each factor on the performance of fiber fineness and strength, and by orthogonal experiment and fuzzy process to determine fiber The bestprocess performance testing NaOH concentration7g/L, H2O230ml/L, scouring temperature90?,scouring time90min, the resulting technology fiber fineness13.40dtex, strength2.40cN/dtex; Apreferred process for the concentration of NaOH8g/L, H2O210ml/L, scouring temperature85?,scouring time90min, the resulting technology fiber fineness15.18dtex, strength2.65cN/dtex; Bpreferred process for the NaOH concentration7g/L, H2O210ml/L, scouring temperature80?,scouring time70min, the resulting technology fiber fineness17.04dtex, strength2.87cN/dtex;optimum process C NaOH concentration of7g/L, H2O220ml/L, scouring temperature85?,scouring time80min, the resulting fiber technology fineness15.30dtex, strength2.62cN/dtex,and all test indicators (residual gum content, residual lignin content, fineness, strength) of theoptimal process for the concentration of NaOH8g L, H2O210ml/L, scouring temperature85?,scouring time90min; optimum technology for the NaOH concentration7g/L, H2O220ml/L,scouring temperature85?, scouring time80min; special fiber technology for the development oflow NaOH concentration7g/L, H2O230ml/L, scouring temperature90?, scouring time90min.(4) the design of different residual gum content and a different fiber fineness of the processconditions, the development of the vine PMFT half degumming fiber products, combined withtwo cook degumming process optimization experiments, explore while maintaining residual gumcontent, and can effectively reduce the residual optimization of process lignin. And to PMFTrattan phloem half unglued alkali-oxygen one bath process as the core, applied research and otherpre-acids, enzymes and ultrasonic pretreatment different ways in terms of PMFT rattan phloemunglued made a preliminary exploration. The results showed that: two cooking process caneffectively reduce the residual lignin content, ultrasound can improve fiber properties.
