Preparation,characterization, and some physical properties of polypropylene/poly(methyl acrylate)‐grafted glass wool composites

Polypropylene/poly(methyl acrylate)‐grafted glass wool (PMA‐g‐GW) mixes were prepared. The polymerization process was carried out using potassium persulfate (PPS) and PPS/acetone sodium bisulfite (ASBS) as a redox‐pair initiation system at 60 and 70°C. The effect of using PPS or PPS/ASBS on the grafting percent and conversion percent reveals that the conversion percent values on using PPS as an initiator are higher than those of PPS/ASBS, while in the case of grafting, the inverse is true, that is, using PPS as an initiator gives grafting percent values lower than those that can be obtained using PPS/ASBS. The dielectric properties, thermal diffusivity, specific heat capacity, and thermal conductivity of PP loaded with modified glass wool as a function of different types and concentrations of initiators—used in the grafting polymerization process, namely, PPS and the redox initiating system—were also studied. © 2002 Wiley Periodicals, Inc.

Lanaset染料染色性能的研究

实验结果证明了硫酸铵替代Albegal SET的可能性，其染色牢度和匀染性都达到了Lanaset染色体系要求的标准,并具有更高的上染率。与中性染料相比，条染复精梳制成率提高3.6％．纺纱制成率提高4.0％。     

琥珀酰亚胺酯基类偶氮染料的制备及其超临界CO2羊毛清洁化染色

以对氨基苯甲酸和4-氨基-2-氯苯甲酸、苯胺和间甲苯胺为原料,采用重氮偶合反应制备染料前驱体,通过在前驱体上引入琥珀酰亚胺酯获得4例活性分散染料Ⅰ～Ⅳ.对染料的紫外-可见吸收光谱、光热稳定性、超临界二氧化碳(scCO2)中羊毛纤维的染色工艺等进行了测试.结果表明,4例染料均具有良好的光热稳定性,染料Ⅰ、Ⅲ和Ⅳ最大吸收波长集中在360～370 nm,染料Ⅱ的最大吸收波长红移到379～452 nm,染料均具备scCO2染色的条件.染料Ⅰ和Ⅲ的最佳染色条件为2 h、80℃和15 MPa,染料Ⅱ的最佳染色条件为1.5 h、80℃和15 MPa,染料Ⅳ的最佳染色条件为2 h、80℃和24 MPa.染色后的羊毛纤维的耐皂洗和耐光色牢度都可达4～5级,固色率最高可达86％,相比于未活化的前驱体,耐皂洗色牢度能提高2～3级,固色率最高能提升63％.SEM和显微镜成像证明4例染料具有良好的透染性,且能均匀附着于纤维的表面和内部.力学性能测试表明,染色后的羊毛纤维能基本保持原有的力学性能.     

贴身穿竹毛混纺针织物开发及性能测试

Differences in wearer response to garments for outdoor activity

The performance of garments for outdoor activity was compared. Three fabrics, each in garments for the upper body, matched garment/wearer dimensions, were worn by 10 athletically ‘well-trained’ males under controlled conditions (hot 32 ± 2°C, 20 ± 2% relative humidity (RH); cold 8 ± 2°C, 40 ± 2% RH) with physical (instrumental) and sensory responses obtained during the trials. Differences in human responses to the fabrics/garments included heart rate, core temperature during run (hot, cold), rest (hot) and walk (cold), heat content of the body, humidity under garments during rest and run and time to onset of sweating. No such differences were identified for change in body mass, core temperature during walk (hot) and rest (cold), skin temperature, temperature of skin covered by the garment, humidity under the garments during walk or for any perceptions (thermal sensations, thermal comfort of torso, exertion, wetness). The garment in single jersey wool fabric performed best in both hot and cold conditions. Effects of garments on wearers are often related to properties of the fabrics from which the garments are made. This study shows that only some differences in fabric properties result in measurable thermophysiological and perceptual responses of the garment wearers and underlines the difficulty in predicting performance of garments/persons from laboratory tests on fabrics.
