纖維被七孔被知識普及 七孔被是什么

常聽(ting)人(ren)(ren)們說什么“七孔(kong)(kong)(kong)被(bei)”、“九孔(kong)(kong)(kong)被(bei)”，究(jiu)竟(jing)這“七孔(kong)(kong)(kong)”、“九孔(kong)(kong)(kong)”是(shi)何(he)意思呢？原來，這說的(de)(de)是(shi)“纖(xian)維(wei)被(bei)”的(de)(de)不同分類。纖(xian)維(wei)被(bei)又(you)被(bei)稱為“太空(kong)棉”，是(shi)用滌(di)綸、人(ren)(ren)造纖(xian)維(wei)等物質(zhi)(zhi)做成，“孔(kong)(kong)(kong)”指的(de)(de)是(shi)一(yi)條(tiao)纖(xian)維(wei)中(zhong)的(de)(de)空(kong)芯(xin)部位，孔(kong)(kong)(kong)前面的(de)(de)數字(zi)表示所使用的(de)(de)纖(xian)維(wei)中(zhong)空(kong)芯(xin)的(de)(de)個數。市面上的(de)(de)纖(xian)維(wei)被(bei)主要分為四孔(kong)(kong)(kong)、七孔(kong)(kong)(kong)和九孔(kong)(kong)(kong)三種，品(pin)(pin)質(zhi)(zhi)的(de)(de)評定一(yi)般由孔(kong)(kong)(kong)數來分，孔(kong)(kong)(kong)數越(yue)多的(de)(de)被(bei)子透氣性越(yue)高(gao)，品(pin)(pin)質(zhi)(zhi)越(yue)佳。

七孔九孔棉(mian)概念科學認識：

所謂“七孔(kong)(kong)棉(mian)(mian)”、“九孔(kong)(kong)棉(mian)(mian)”其實(shi)是(shi)(shi)化(hua)(hua)纖，帶孔(kong)(kong)的(de)(de)棉(mian)(mian)被(bei)內芯都不是(shi)(shi)棉(mian)(mian)，而(er)是(shi)(shi)化(hua)(hua)纖產品。國家(jia)目(mu)前對(dui)多(duo)(duo)空枕(zhen)(zhen)頭并沒有標準，對(dui)多(duo)(duo)孔(kong)(kong)纖維的(de)(de)含量也沒有具體要求(qiu)，據說(shuo)實(shi)際含量是(shi)(shi)多(duo)(duo)少，是(shi)(shi)0%，還是(shi)(shi)10%到100%都可(ke)稱(cheng)為(wei)七孔(kong)(kong)或九孔(kong)(kong)枕(zhen)(zhen)，市場(chang)甚至出現了11孔(kong)(kong)，12孔(kong)(kong)枕(zhen)(zhen)頭。“七孔(kong)(kong)棉(mian)(mian)”、“九孔(kong)(kong)棉(mian)(mian)”，其實(shi)這些產品都應當稱(cheng)為(wei)“滌綸纖維”和“棉(mian)(mian)”根本不沾邊。關于(yu)所謂“孔(kong)(kong)的(de)(de)”數量，更是(shi)(shi)無從考(kao)究，《枕(zhen)(zhen)頭記》引(yin)用中(zhong)國纖維行(xing)業權威儀(yi)征化(hua)(hua)纖的(de)(de)介紹，目(mu)前技術最先進(jin)的(de)(de)儀(yi)征化(hua)(hua)纖工(gong)廠僅僅生產一(yi)孔(kong)(kong)的(de)(de)中(zhong)空纖維，不存在七孔(kong)(kong)或者九孔(kong)(kong)纖維，市場(chang)上面多(duo)(duo)數七孔(kong)(kong)或者九孔(kong)(kong)纖維均(jun)系(xi)中(zhong)空棉(mian)(mian)。
