什么叫做七孔被，怎样挑选？

七孔被是化纤产品。它的原理是在一根化学纤维上均匀地打七个孔，使之富含空气，达到保温效果。打孔后的化学纤维也显得十分松软，形状易于恢复，盖得时间久了，也不会像棉花被那样被压紧压实变硬，只要经常拍打一下，就能恢复原来的形状，被子可以一直保持蓬松状，因此保温性也就一如既往了。

七孔被挑选方法

1：可以先买对枕头试试

不同厂家生产的七孔被质量相差很大，价格也有很大的差别，因此若想买一条称心如意的被子，首先要认准品牌。由于七孔被的价格相对较高，因此在买七孔被之前，如果条件允许，可以先买一对七孔棉的枕头试试。这样做的好处，一是枕头的价格相对较低，可以用较小的代价来试一下七孔棉是不是适合自己；二是可以通过这对枕头的质量，来确认生产厂家的情况。一般来说，能够生产出高质量七孔枕的厂家，生产的七孔被也一定很好。

2：需要看看含量

选购七孔被时先要看一下被子里面七孔棉的含量。有些标识虽为七孔棉的被子，里面的七孔棉并不是百分之百，而只是占了一定的比例。目前有关部门还没有规定标准，只有当七孔棉占了多大的比例的时候才可称为七孔被，因此消费者在选购时，一定要看清七孔棉的含量。应该选购七孔棉含量为百分之百的七孔被，这样质量更稳定。

3：注意选用季节

买七孔被与平常所用的棉花被不太一样，不必去看是四斤的，还是六斤的，甚至是八斤的，七孔被一般都在三斤左右，选购七孔被的标准是按使用的季节划分的：冬被，春秋被，或者是空调被。冬被一般适用于室内温度在4－12°C，春秋被适用于室内温度12－22°C，空调被则适用于室内温度在22°C以上。

4：被子面料也很重要

选购时，应先把被子拿出来，看看被子的面料是不是高支纱全棉的，面料是否紧密。因为面料紧密了，才能保证被子里面的化学纤维填充物不会外逸。同时，可以用手摸一下，被子是否显得十分柔软滑爽。好的被子应该十分滑爽，一放开，就自然回复到原样。假如感觉有点滞粘，就表明纤维填充物不是百分之百的七孔纤维，或者七孔纤维的质量很差。

5：不要忽视针脚

然后可以把被子平铺，看看整体上是否平整，看看厚薄是否均匀，特别是要看看被子的四条边，是否自然，成一条直线。整体看完之后再看缝道，先看直不直，再看线脚匀不匀，最好用手量一下，一虎口有几针，再换个地方量一下，看看是不是还是这些针数。好的被子应该缝道笔直，针脚一致，这里是几针，换一个地方不多不少还是这几针。
