在我国,汽车已经成了每家每户的必需品,汽车已经普及到我们千千万万的平常百姓家里了。我国汽车行业发展迅速,早在2009年,我国的汽车生产量已经超过了日本,成为了全球汽车产量最大的国家。汽车制造工业属于工业战略产业,通俗来讲就是综合性工业,汽车制造业的发展可以对很多的相关产业,如石油业、冶金业、橡胶业、塑料业、仪器仪表等行业产生极大地促进作用。随着人们生活质量的提高,人们开始追求一些深层次的事物,不再仅仅局限于汽车的整体性能、质量等问题上,人们的目光已经逐渐转移到了汽车的内饰上,而在汽车内饰里,汽车座椅是最为重要、最为关键、也是被人关注最多的地方。随着科技的发展,目前已经出现了一种新的材料——超纤皮,并逐渐将其应用到了汽车座椅上,并受到了大家的喜爱,其具有真皮座椅无法比拟媲美的优点。本文就将通过研究展示超纤皮在代替真皮应用于汽车座椅上具有的优越性及可行性等方面,让大家能更充分的了解超纤皮这种新型材料。 相似文献

Amino‐functionalised siloxanes have been used to increase the number of active sites in leather (and especially suede) available for dye fixation. The use of a second hydrophobic siloxane in conjunction with the amino‐functionalised siloxane, further increases the fastness results. The best results are found for the use of reactive dyes on siloxane pre‐treated leather samples, where washfastness and perspiration fastness results of 4–5 or 5 for all fibres on a multifibre staining material for a commercially acceptable black are obtained. Wet and dry crock fastness of 3 is reached. 相似文献

This paper presents a computational approach for designing, mixed fiber filter media for depth filtration. The goal is to find an optimum solution, given the range, for a set of design parameters: thickness of the media, diameter of microfiber, and diameter of nanofiber, surface area ratio of nanofiber to microfiber and mass of microfiber. The objective of this work is to develop a software program that can be used as an aid to accelerate filter design and reduce the number of laboratory experiments.This program applies a Genetic Algorithm to search for an optimum filter media design based on quality factor which quantifies the filter performance. A user friendly computer program is developed that provides inputs, outputs and controls to design a filter media. The program provides a starting point for constructing filter media for testing and design for particular applications. 相似文献

A gradient extraction method was developed and used for a synthetic leather made of polyurethane (PU) and microfiber polycaprolactam (PA‐6), by which the two components were separated using DMF and formic acid as solvents, respectively. Their chemical structure was confirmed by FTIR spectra, and the result showed that the PU is a kind of polyester polyurethane with phenylene rings in the molecule. The condensed phase structure was analyzed using X‐ray diffraction (XRD). The crystallinity of the PA‐6 is about 65.6%, and for the PU, there was not distinct crystalline character shown in the XRD pattern but a phase separation structure of hard block‐soft block with the hard domains content about 58.7%. SEM images showed that the PA‐6 microfibers transfixing the PU matrix form a net bundle structure, and there are two kinds of porous structures in the synthetic leather, with one type of pore sized 5–80 μm between the components of PU and PA‐6, and the other in PU matrix with a size of 0.1–2 μm. The multipores run through the synthetic leather as three‐dimensional channels, benefit for transportation of air, water, dyes, and so on. © 2006 Wiley Periodicals, Inc.
