MALDI-TOF MSを用いた再生カシミヤ繊維の定量的鑑別
Recently, as concern of sustainable growth of society is increasing, it has been noted that raising cashmere goats can have a negative impact on our environment. In an effort to reduce the number of grazed animals, there is an increasing demand for recycled cashmere in apparel and textile industries. Meanwhile, the lack of analytical methods to obtain an appraisal parameter relative to the presence of recycled fibers in textiles is still a significant issue. Whereas optical microscopy is a useful method to observe changes in shape of the fibers, there is no other testing method to quantify the recycled cashmere. We will report the results of multiple regression analysis incorporated with an index of recycled samples using MALDI-TOF MS and the ratio of the abnormal shape determined using the microscope. The index obtained with MALDI-TOF MS and observation by optical microscopy enable a quantitative discrimination between recycled and virgin cashmere.
