自工业革命发明了轧花和纺织机械以来,棉花在纺织原料中的地位简直是扶摇直上,迅速升居要津。虽然近些年来,人造纤维有了很快发展,但仍远不能与棉花相比。至今全世界纤维消费量中,棉花仍遥遥领先。讲起穿衣,人们自然会想到棉花。但是说到吃油,那就要数大豆、花生、菜籽、芝麻……,常常忘掉了棉花。其实,棉花不仅是纤维之首,而且还是很重要的油料之一呢。籽棉经过轧花后剩下的棉子,可以榨成棉子油;这是大家知道的。可是你知道棉子油产量有多大?棉子含油率高达17—21.6％。以1957年来说,我国生产的棉花为492万吨,可轧出的棉子约为328万吨,除留 Since the Industrial Revolution invented ginning and textile machinery, the status of cotton in textile raw materials has been skyrocketing and it has quickly risen to the point of wanting. Although man-made fibers have developed rapidly in recent years, they are still far from cotton. To date, cotton is still ahead of the world in fiber consumption. When people talk about dressing, people naturally think of cotton. But when it comes to oil, there are a lot of soybeans, peanuts, rapeseeds, sesame seeds... and often forget about cotton. In fact, cotton is not only the first fiber, but also one of the most important oils. Seed cotton can be squeezed into cotton seed oil after it has been ginned. This is known to everyone. But do you know how much cotton seed oil is produced? The oil content of cotton seeds is as high as 17-21.6%. In terms of 1957, China produced 4.92 million tons of cotton, and about 3.28 million tons of cotton could be rolled out.
