摘要/Abstract

摘要： 针对笔者提出的用着（显）色法结合图像处理法解决棉麻纤维自动识别和混和含量测试问题，重点研究了对棉麻等纤维素纤维着（显）色鉴别的方法和条件，发现了为使棉麻着（显）色差异最大化，需在着（显）色前对试样进行溶胀处理，在着（显）色后将被测试样置于低温环境下测试的方法；还研究了碘-纤维素加成物呈色机理及其影响因素。发现在常温下，由于棉能与碘形成加成物，棉麻着（显）色稳定性方面前者大于后者，且随时间棉麻着（显）色差异逐渐减小；在低温下，无论棉麻，碘着（显）色相当稳定，且棉、苎麻之间着（显）色差异最大；此外，对焦对纤维颜色影响很大。研究结论对棉、麻等纤维混和含量自动测试具有重要意义。

Abstract: In order to identify cotton and ramie and determine blending ratio of cellulose fibers based on stain and image process method, a new method for staining cellulose fibers and its preprocess condition is researched. It is found that swelling process before staining sample and testing under low temperature environment is necessary to maximize the color difference between cotton and ramie. Color forming mechanism and its influence factors are also researched. It is found that color stability in cotton is better than in ramie because of cellulose-iodine compound formed in cotton and color difference between cotton and ramie is narrowed with time elapsing under atmospheric temperature. It is also found that color stability for cotton and ramie is good and color difference among regenerated fibers, cotton and ramie is maximized under low temperature. In addition, focusing play an important role in determine stained color of fiber. The result will play a important role in determining blending ratio of cotton/ramie textile automatically.

Key words: Determining blending ratio of cotton and ramie, Stain method, Compound, Testing under low temperature
