问题 问答题 简答题

你所认为的纤维未来应如何发展?你所感觉的纤维发展及未来最主要的问题是什么?

答案

参考答案:

1.在天然纤维方面。积极寻求和开发新的和可持续发展的天然纤维资源是极为重要

的。

2.在再生纤维方面。依靠天然生长的纤维在纤维长度、细度、和性能上较难控制,有时无法用于纺纱。而且天然纤维素、蛋白质物质,并非能直接满足纺用纤维的要求,加上废弃的纤维及其制品,人们极有必要解决这些物质的再生利用。

3.在合成纤维方面。仿生化、功能化、高性能化纤维将是今后的发展方向。

最主要的问题:

由于人口膨胀、环境的污染和恶化,自然资源与能源的匮乏,人类对物质量的需求提高,人类穿、用消耗的资源---纤维将成为未来发展中必须直面的问题。在纤维未来的发展中,人类应该更多的关注已有纤维的使用和再生利用,可持续天然纤维的开发利用,低能耗、清洁化纤维的加工,即特别关注大宗类纺织品用纤维资源的可持续性。

单项选择题

It was two years ago today that the hunting ban came into force, supposedly ending centuries of tradition. However, the law has been an unmitigated failure-not that either side is shouting about it.
It was a nightmare vision that struck fear and loathing into the hearts of millions. When the hunting ban became law, it was said, 16, 000 people would lose their jobs, thousands of hounds would be put down, rotting carcasses would litter the countryside, hedgerows would disappear, riders would face on-the-spot fines, law-abiding people from doctors to barristers would be dragged from their horses and carted off to prison, while dog owners would be prosecuted if their mutt caught a rabbit.
These were just some of the claims as desperate countryside campaigners battled to save their sport in the lead-up to the hunting ban, which Labour rammed into law using the Parliament Act on November 18, 2004.
For many, the fears were real. Others exaggerated as they fought an increasingly aggressive anti-hunting lobby which had rejected acres of independent evidence affirming that hunting is the most humane way of killing foxes. In the battle to"fight prejudice, fight the ban", every emotive argument was deployed.
For its part, the anti-hunting brigade extravagantly claimed that the ban would put an end to the rich parading in red jackets. A senior Labour MP, Peter Bradley, admitted in this newspaper that it was, as many suspected, about "class war". He lost his seat shortly afterwards. But people in red coats did not disappear.
In fact, none of the forecasts came true. What did happen was something nobody had predicted: the spectacular revival and growth of hunting with hounds. In short, the hunting ban has been a failure.
Today, on the second anniversary of the ban’s coming into force on February 18, 2005, new figures show that participation in the sport has never been higher. It is so cheerful that two new packs have been formed, something that has not happened for centuries.
They include the seductively named Private Pack, set up by the financier Roddy Fleming in Gloucestershire. It operates on an invitation-only basis, a sort of hunting private members’ club. This can only mean one thing: like it or not, hunting is cool. Young people are taking it up, enticed by the element of rebellion and the mystique of what actually happens as hunts attempt to keep within the law.

The anti-hunting lobby held that ______.

A.fox-hunting was an expression of prejudice

B.the countryside campaigners were reasonable

C.the theory of humane killing did not hold water

D.the hunters exaggerated the dreadful scene of hunting
