Grafting Copolymerization of Styrene and Acrylic Acid onto Pre-irradiated Polypropylene Fabric

l introductionGrafting polytnerization is a valuable method forthe modification of the chemical and physicalProperties of polymer surfaces. It can provide somedesirable Properties such as biocompatibility['],.ion-exchWe['] and thermo-sensitivity['], etc. somemethods have been studied in grafting polymerizstion,for example, ionization irradiation['], ultravioletlight['], plasma, chemical initiators and others[6].Radiation grafting is one of the most Promisingmethods because it can be effective…     

冷冻胚胎的法律属性探析

社会转型期经济的迅猛发展,带动了科技的突飞猛进,一系列在人类伦理纲常接受范围外的生命再生现象开始出现。冷冻胚胎这一新的"物种",对现阶段我国《物权法》中"物"现有的含义提出了挑战,"失独老人"胚胎争夺案将原本属于理论界的问题提到了实践层面。冷冻胚胎的法律属性,成为学术界和实务界争议的焦点。通过论证,冷冻胚胎应定位为具有潜在人格属性的物,其本身并不能脱离现有的物的范畴,只在保护方式上给予倾斜。     

高牢度锦/氨纶织物加工工艺探讨

锦/氨纶织物具有抗酸碱性、耐汗酸侵蚀、耐盐分和耐摩擦等综合优点,是服装加工类重要的材料,但是锦/氨纶织物存在染色上的牢度不高的通病,这不仅会造成锦/氨纶织物在使用中脱色,更容易形成锦/氨纶织物类纺织产品市场份额的下降,需要对锦/氨纶织物的染色加以重点研究.本研究以锦/氨纶织物的染色加工工艺为主要研究对象,在变换染色剂种类、染色次数、染色方式等参数的基础上,对锦/氨纶织物实现染色高牢度进行了探讨.     

Activated Carbon Fabric Mask Reduces Lead Absorption and Improves the Heme Biosynthesis and Hematological Parameters of Battery Manufacturing Workers

Activated carbon fabrics (ACF) mask prevents the absorption of lead and reduce its adverse effects of human health. Aim of this study to know the blood lead level and its effects on heme biosynthesis and hematological parameters after using 2 months activated carbon fabric mask of battery manufacturing workers (BMW). Blood lead level, heme biosynthesis and hematological parameters were measured by using standard method. Blood lead level (P < 0.001, − 13.5%) was significantly decreased, activated δ-aminolevulinic acid dehydratase (P < 0.001, 11.97%) and non-activated δ- aminolevulinic acid dehydratase (P < 0.001, 23.17%) enzyme activity were significantly increased, however, the ratio of activated to Non-activated δ- ALAD (P < 0.001, − 10.13%) was significantly decreased, urinary excretion of δ- aminolevulinic acid (P < 0.001, − 10.49%) and porphobilinogen (P < 0.001, − 7.38%) were significantly decreased after using 2 months ACF mask as compared to before using mask of BMW. Hematological parameters i.e Hb (P < 0.05, 13.42%), PCV (P < 0.05, 7.23%), MCV (P < 0.05, 1.9%) were significantly increased and total WBC count (P < 0.05, − 5.18%) was significantly decreased after using 2 months ACF mask as compared to before using mask of BMW. Two months using ACF mask reduces the blood lead level and improves the δ-ALDH activity and hematological parameters, decreases the urinary excretion of δ-ALA, PBG of battery manufacturing workers. Therefore, the regular using of ACF mask is beneficial to prevent the lead absorption and its adverse effects on human health.

中国纺织业现状与服饰设计研究

中国家用纺织品行业的不景气,并非仅仅是“设计”的落后,而是纺织行业整体综合技术实力的问题。当前中国“家纺设计”的落后现状主要是由于陈旧的染织设计教育模式及落后的设计文化导致。针对目前“家纺设计”现状,中国的“家纺设计”可以两条腿同时走路。一方面紧追国际家纺时尚潮流,加强对世界家纺设计文化研究,促进中国现代时尚家纺设计;另一方面应当加强对中国传统家纺设计文化的研究,设计开发出具有时代性和时尚性的采用中国传统技艺制作的世界一流家纺产品,以促进中国家用纺织品行业的发展。
