基于标准气体发生器和检知管搭建了消臭性能测试系统,定量测试了几种纤维对汗臭的3种主要成分醋酸、氨气和异戊酸的消臭率及消臭速率。结果表明:天然纤维中毛纤维具有突出的汗臭味消除功能,其次是棉纤维;合成纤维中,改性的消臭腈纶纤维的消臭性能格外突出,其次是Modal纤维,而涤纶和丙纶纤维的消臭性能最差。同时,消臭腈纶对氨气的消臭速率最高,其次是毛、Modal、棉和大麻,最差的是涤纶纤维。毛、大麻、消臭腈纶纤维、棉和Modal纤维对醋酸的吸附效果都比较好,但涤纶的吸附效果显著较差。感官测试表明,羊毛纤维和消臭腈纶纤维制成的袜子消臭效果比较好,和定量测试结果一致。对于消臭效果良好的纤维构成的纺织品,其消臭性能与纺织品质量相关,质量越大,消臭效果越好。 相似文献

纺织品消臭整理研究进展 总被引:5,自引:0,他引:5
本文介绍了纺织品消臭整理的重要性及研究进展。消臭整理遵循四种原理:物理吸附、化学反应、掩盖和生物除臭。通常有原丝改良和后整理加工两种加工方法,加工药剂种类繁多,但发展趋势为绿色环保型。消臭加工的评定方法有两类:官能实验和化学分析。 相似文献

Emotional sweating and malodour production represent a relevant challenge to today’s antiperspirant (AP) and deodorant products as stress in everyday life increases continuously. The aim of this study was to investigate stress‐induced sweating in teenagers who are known to experience various stressful situations, e.g. exams at school or job interviews. To induce emotional sweating in 20 female and 20 male adolescents (16–18 years of age), we applied the Trier Social Stress Test (TSST), considered today to be the most reliable and standardized stress protocol. In this study, we demonstrate that the TSST induces high amounts of sweat and strong axillary malodour in the tested age group. Notably, male teenagers showed significantly higher stress‐induced odour scores than female subjects, although no gender differences were detected concerning other physiological stress markers. Testing of a novel deodorant/AP product developed to specifically address the needs of adolescent consumers revealed excellent deodorant and AP efficacy under the challenging conditions of the TSST. 相似文献

Double-blind cross-over trials in which trained assessors evaluated axillary malodour on a 0 to 10 scale showed that ethanol at 60% and 99% w/w significantly reduced odour for up to 24 h. Reduction in odour was increased by the addition of non-volatile antimicrobial ingredients such as chlorhexidine, Irgasan DP 300 (Triclosan, Ciba Geigy) or aluminium chlorhydrate.
Volunteer panellists were able to identify statistically significant deodorant effects when they rated their own axillary odour on a 0 to 10 scale.
An odour absorber, zinc ricinoleate (Grillocin, Grillo-Werke, A. G.) was used to treat existing malodour and gave reduced perception of that malodour for up to 24 h.
A close correlation was found between panel odour scores and the bacterial status of the axilla as assessed by the replipad technique when biocidal systems were studied. Irgasan DP 300, a bacteriostat, did not perform so well in skin flora sampling procedures, but was nevertheless effective as a deodorant ingredient. Thus in vivo microbiological techniques, although often useful as predictors of deodorancy, do not replace the carefully controlled clinical trial with direct assessment of odour.
