It was found silane could be easily grafted onto CF surface through covalent bonds under 5% water content. This modification led to the transformation of surface wettability of CF from hydrophilic to hydrophobic. Interestingly

A review on room-temperature self-healing polyurethane: synthesis, self-healing mechanism and application J. Leather Sci. Eng. Pub Date : 2022-08-30 Li, Yupeng, Jin, Yong, Fan, Wuhou, Zhou, Rong
Polyurethanes have been widely used in many fields due to their remarkable features such as excellent mechanical strength, good abrasion resistance, toughness, low temperature flexibility, etc. In recent years, room-temperature self-healing polyurethanes have been attracting broad and growing interest because under mild conditions, room-temperature self-healing polyurethanes can repair damages, thereby

Essential role of isoelectric point of skin/leather in leather processing J. Leather Sci. Eng. Pub Date : 2022-08-25 Wang, Ya-nan, Hu, Longyu
Leather, made from animal hide or skin, is mainly composed of collagen. Collagen is a type of fibrous protein. The basic amino acid residues (lysine, arginine and histidine) and acidic amino acid residues (glutamic acid and aspartic acid) of the protein confer zwitterionic character to collagen, making the protein positively or negatively charged at different pH values. The pH at which the net charge

Functional non-glutaraldehyde treated porcine pericardium for anti-coagulation, anti-calcification, and endothelial proliferation bioprosthetic heart valves J. Leather Sci. Eng. Pub Date : 2022-08-20 Chen, Xiaotong, Yu, Tao, Kong, Qunshou, Kuang, Dajun, Xu, Hong, Zhao, Zhiyu, Yang, Li, Li, Gaocan, Fan, Haojun, Wang, Yunbing
In the last decade, the number of transcatheter heart valve replacement for severe heart valve disease has increased exponentially. Although the bioprosthetic artificial heart valve (BHV) has similar fluid dynamics performance to the original heart valve compared with mechanical heart valve so that there is no need to take long-term anticoagulant drugs to prevent thromboembolism, transcatheter BHV

An exploration of enhancing thermal stability of leather by hydrophilicity regulation: effect of hydrophilicity of phenolic syntan J. Leather Sci. Eng. Pub Date : 2022-08-15 Sun, Qingyong, Zeng, Yunhang, Yu, Yue, Wang, Ya-nan, Shi, Bi
Effect of retanning on the thermal stability of leather is eliciting increasing attention. However, the relationship between the hydrophilicity of retanning agents and the heat resistance of leather and the corresponding mechanism remain unclear. Herein, phenolic formaldehyde syntans (PFSs) were selected as models to explore the effect of the hydrophilicity of retanning agents on the thermal stability

Technical and technological constraints facing Tanzania leather value chain: a snapshot of intervention measures J. Leather Sci. Eng. Pub Date : 2022-08-10 China, Cecilia Rolence, Elibariki, Rahel, Msami, Jamal, Mwombela, Stephen, Wilson, Lugano
The leather value chain starts with livestock, the key source of hides and skins, and the main raw materials for the industry. Despite having the second-largest livestock population in Africa, Tanzania is only the 11th largest exporter of leather on the continent, underlining the disproportionate contribution of the sector to the economy. This study presents the results of a recent assessment aimed

Laccase-functionalized magnetic framework composite enabled chlorophenols degradation, a potential remediation for fungicides residues in leather J. Leather Sci. Eng. Pub Date : 2022-07-25 Cao, Min, Yu, Jie, Zhang, Xing, Lin, Yamei, Huang, He
Chlorophenols, used as the fungicides in leather, are strictly limited in leather products. In this work, a metal–organic framework material, zeolitic metal azolate framework-7 (MAF-7), was first used to encapsulate laccase (Lac) to prepare MAF-7/Lac bio-composites with 98.5% immobilization yield. Afterward, Lac/MNP@MOM was formed by introducing the magnetic nanoparticles (MNPs) into the Lac@MOM. MAF-7

Advances on the modification and biomedical applications of acellular dermal matrices J. Leather Sci. Eng. Pub Date : 2022-07-05 Chen, Yining, Liu, Xinhua, Zheng, Xin, Huang, Xuantao, Dan, Weihua, Li, Zhengjun, Dan, Nianhua, Wang, Yunbing
Acellular dermal matrix (ADM) is derived from natural skin by removing the entire epidermis and the cell components of dermis, but retaining the collagen components of dermis. It can be used as a therapeutic alternative to “gold standard” tissue grafts and has been widely used in many surgical fields, since it possesses affluent predominant physicochemical and biological characteristics that have attracted
