不同腰位牛仔裤穿着舒适性评价

采用真人试穿和主观评价的方法,对9件不同腰位的牛仔裤进行着装实验评价并进行压力舒适性评价.发现所有牛仔裤在穿着的过程中都能满足人体舒适性的要求,其中腰上口位于髋骨上2cm,前中下降1.5cm是最舒适的腰位设计,为合体舒适牛仔裤设计提供技术基础.     

水解酸化/生物接触氧化/沉淀工艺处理牛仔衣染色废水

针对牛仔衣染色(以靛蓝染料为主)废水色度较高、有毒性及污染严重的特点,确定采用水解酸化/生物接触氧化/沉淀的工艺处理该废水.在丽发制衣厂的应用实践表明:该工艺切实可行,运行费用低,处理效果稳定,出水水质达到DB 44/26-2001中一级排放标准,COD、BOD5、SS、色度去除率分别达到94%、92%、87%、83%.

表面活性剂对牛仔布生化酶洗效果的影响

通过在牛仔布生化酶洗过程中加入不同种类的表面活性剂试验,分别分析了阴离子表面活性剂、阳离子表面活性剂和非离子表面活性剂对牛仔布生化酶洗处理的影响规律。试验表明各种表面活性剂对于不同牛仔布的酶洗效果影响规律基本相似,随浓度不同,各种表面活性剂对酶活力和反应速度的影响规律有所不同。     

Novel Design of UWB Jeans Based Textile Antenna for Body-Centric Communications

This research presents an ultra-wideband (UWB) textile antenna design for body-centric applications. The antenna is printed on a 1 mm thick denim substrate with a 1.7 relative permittivity. The jeans substrate is sandwiched between a partial ground plane and a radiating patch with a Q-shaped slot. The slotted radiating patch is placed above the substrate and measures 27.8 mm × 23.8 mm. In free space, the antenna covers the ultra-wideband spectrum designated by the Federal Communication Commission (FCC). Various parameters of the antenna design were changed for further performance evaluation. Depending on the operating frequency, the antenna's realized gain varied from 2.7 to 5 dB. The antenna achieved high radiation efficiency with an omnidirectional radiation pattern. A parametric study was performed in research on varying antenna substrates and other components of the antenna. The three outermost layers of the human body are used to model a human phantom for on-body simulation. After that, the antenna was placed at five different distances from the phantom. The findings demonstrate that at close distances to the phantom, the antenna's gain and efficiency at lower frequencies are reduced. The antenna's radiation efficiency and gain were much higher at higher frequencies for distances greater than 6 mm. Compared to free space, the antenna's radiation pattern was more omnidirectional, especially at higher frequencies. This antenna is novel, compact and has an ultra wide bandwidth, a maximum of 94.60% radiation efficiency and a 5 dBi gain that will make it a good candidate for body-centric communications.

云芝漆酶在牛仔布生物整理中的应用

采用漆酶与酸性纤维素酶协同作用来降低牛仔布生物整理中的返沾色。结果表明:单独添加酸性纤维素酶虽然除毛效果好、剥色明显,但靛蓝染料对牛仔布的返沾色较重。而添加漆酶与酸性纤维素协同整理时,可以显著减少返沾色;当漆酶用量为5.0 g/kg牛仔布时,牛仔布的返沾程度减少83%,协同水洗时间以60 min为宜。牛仔布水洗整理的工厂放大试验显示:漆酶与酸性纤维素酶协同作用,一方面可使牛仔布的返沾色显著减弱,获得独特的“雪花”效果;另一方面还可使工厂废水中的靛蓝含量减少80%,有利于降低环境污染。
