Distribution of fabric softeners on cotton terry cloth was studied using scanning electron microscopy and energy dispersive
X-ray analysis. The unsaturated groups in the quaternary fabric softeners were tagged with osmium tetroxide to provide contrast
in the microscopy. Longitudinal specimens showed the fabric softeners distributed over the cotton fiber surfaces with more
in the crenulation of the fiber. Cross sectional specimens revealed that the fabric softener was distributed throughout the
cotton fibers with higher concentrations of fabric softener observed in the lumen and crenulation than in the secondary wall
and non-crenulated fiber surface. This distribution of fabric softener is consistent with deposition on both external fiber
surfaces and internal fibril surfaces. The deposition and final surface coverage is strongly dependent on the pH value of
the washing medium. Repeated treatment cycles with fabric softener using a higher pH washing media resulted in higher concentrations
of fabric softener on and within the cotton fibers. Neutral or lower pH washing media resulted in a somewhat constant concentration
of fabric softener on and with cotton fibers with increased number of treatment cycles. Differences in perception of softness
of the treated fabrics are not explained by differences in distribution of the fabric softener; it appear that there is an
optimum amount of softener to achieve the desired sensory response and that further deposition build-up does not increase
perception of softness.

Investigations on the carbonising of wool are reviewed. Anomalous results have been obtained by a number of workers. The moisture content of wool material as it enters the dryer after the acid treatment can greatly affect the extent of damage. There are arguments in favour of carbonising at different points in the processing sequence. These are considered in detail, and form the basis of the work reported in Part II. 相似文献

以镀银涤纶短纤和普通棉为原料制备了抗菌棉涤织物,研究了镀银短纤含量对织物抗菌性能及织物的染整性的影响.结果表明,抗菌棉涤织物具有很好的抗菌性,抗菌率随镀银短纤含量的增加而提高,且与指数函数拟合显著相关.染整工艺中ρ(NaOH)为6g/L以下时,对短纤中银的影响不大;ρ(NaOH)为8g/L时,镀银短纤的抗菌性最好. 相似文献
