皮革及其制品的色彩反映了人的审美诉求,往往是人们选择皮鞋、皮衣、箱包等皮革制品的首要评价特征。因此,皮革染色是制革过程中最重要的工序之一。针对传统染色方法所暴露出的染色不均匀、耐摩擦色牢度及耐水洗色牢度差等问题,该文主要介绍了提高皮革染色性能的方法与清洁的皮革染色技术。首先简要概述了皮革染色原理,然后阐述了染色前处理、添加染色助剂和改性染料3种提高皮革染色性能的方法,同时介绍了超声波技术、微波技术、超临界CO2技术、电化学技术、等离子体技术在皮革染色中的应用,最后对皮革染色的发展趋势进行了展望。 相似文献

Leather residues derived from shoes industry are often incinerated in winter times to warm the working ambient, giving rise to the production of chromium-rich ashes that put environmental problems on its disposal. The power of these ashes as colouring and fluxing agent for industrial porcelain tile formulations and the effects of incorporating different amounts on water absorption and bending strength were evaluated in the present work along a broad sintering temperature range of 1120–1180 °C. The experimental results revealed that the incorporation of these wastes can result in porcelain tiles with superior properties, in terms of water adsorption, density and bending strength. The results also showed the possibility of using these wastes as colouring agents to obtain broad range tonality products from cream to dark brown, depending on the added amount of leather ashes in the formulation and on the sintering temperature. The observed improvements of the final properties of the material and the ability of chromium-rich ashes to replace expensive pigments show that their incorporating in porcelain tiles formulations is a smart way of recycling this environmental dangerous leather derived waste. 相似文献

Leather tanning processes cause environmental impact as a result of the generation of solid waste, wastewater, and release of gases. The improper disposal of such waste may promote the oxidation of chromium, for example, changing it from chromium (III) to chromium (VI), in which becomes extremely toxic. In this study, composites were prepared from natural rubber (NR) with industrial leather waste (Lw), varying the waste amount from 20 to 80 phr, with the aim of recycling leather waste. The microstructure, mechanical properties and rheological properties of composites were investigated. The results showed that Lw increased tensile strength and hardness, with good reproducibility, and uniformity of residuals distributed as fillers (miscible materials). These properties indicate that this composite material can be used as raw material for the manufacture of shoes, bags, upholstery, etc. POLYM.
