摘要:
 荆条是优良编织材料，荆条软化处理试验可为提高其柔软度、研发荆编家具提供理论依据。采用水煮、碳酸氢钠、尿素、乙二胺4种软化处理方法处理荆条，通过测定同跨高比时荆条的最大弯曲挠度、抗弯弹性模量、抗弯强度，分析不同软化处理对荆条纵向弯曲性能的影响。结果表明，4种软化处理的最大弯曲挠度表现为尿素、水煮＞碳酸氢钠＞乙二胺，并随直径的增大而增大，抗弯强度表现为碳酸氢钠＞水煮＞乙二胺＞尿素。弹性模量表现为 尿素＜水煮＜乙二胺、碳酸氢钠，大致随直径的增大而减小。4种软化处理方法中， 尿素处理方法挠度大、抗弯弹模小、抗弯强度能满足使用要求，其软化效果最佳。
Abstract:
Vitex negundo twigs are fine woven materials, in order to improve the flexibility of the twigs and to provide theoretical basis for woven furniture, 4 different softening method were adopted to soft the twigs with the same ratios of span to diameter, such as boiling water, solutions of sodium hydrogen carbonate, urea, and ethylenediamine. The bending performances such as maximum bending deflection, modulus of elasticity and bending strength of the twigs were tested to analyze the effects of the treatments on the bending properties. The results indicated that: the sequence of the maximum bending deflection was urea and boiling water > sodium hydrogen carbonate > ethylenediamine, and the maximum bending deflection increased with the diameter. The sequence of the bending strength was sodium hydrogen carbonate > boiling water > ethylenediamine > urea. The sequence of the modulus of elasticity was urea < boiling water< ethylenediamine and sodium hydrogen carbonate, and the modulus of elasticity generally decreased with the diameter. The large bending deflection and small modulus of elasticity were gained after being treated with urea and at the same time the bending strength could satisfy the requirement, so the softening effect with urea was the best.
