纖維被七孔被知識普及 七孔被是什么
常聽(ting)人(ren)(ren)們說(shuo)什么“七孔(kong)(kong)(kong)被(bei)”、“九(jiu)孔(kong)(kong)(kong)被(bei)”,究(jiu)竟這(zhe)“七孔(kong)(kong)(kong)”、“九(jiu)孔(kong)(kong)(kong)”是(shi)(shi)何意思呢?原(yuan)來,這(zhe)說(shuo)的(de)是(shi)(shi)“纖(xian)(xian)維被(bei)”的(de)不同分類。纖(xian)(xian)維被(bei)又(you)被(bei)稱為“太空棉(mian)”,是(shi)(shi)用(yong)滌綸、人(ren)(ren)造纖(xian)(xian)維等物質(zhi)做成(cheng),“孔(kong)(kong)(kong)”指的(de)是(shi)(shi)一(yi)條纖(xian)(xian)維中的(de)空芯(xin)部位(wei),孔(kong)(kong)(kong)前面(mian)的(de)數(shu)字表示(shi)所使用(yong)的(de)纖(xian)(xian)維中空芯(xin)的(de)個數(shu)。市(shi)面(mian)上的(de)纖(xian)(xian)維被(bei)主要分為四孔(kong)(kong)(kong)、七孔(kong)(kong)(kong)和九(jiu)孔(kong)(kong)(kong)三種,品質(zhi)的(de)評定(ding)一(yi)般(ban)由孔(kong)(kong)(kong)數(shu)來分,孔(kong)(kong)(kong)數(shu)越(yue)多的(de)被(bei)子透氣性(xing)越(yue)高,品質(zhi)越(yue)佳。

七孔(kong)九孔(kong)棉(mian)概念科學認(ren)識:
所(suo)謂(wei)“七孔(kong)棉(mian)”、“九(jiu)孔(kong)棉(mian)”其實(shi)是(shi)化(hua)(hua)(hua)纖,帶孔(kong)的(de)棉(mian)被內(nei)芯(xin)都不是(shi)棉(mian),而是(shi)化(hua)(hua)(hua)纖產(chan)品(pin)。國家(jia)目(mu)前(qian)對(dui)多(duo)(duo)空(kong)枕(zhen)頭(tou)并沒(mei)有標(biao)準,對(dui)多(duo)(duo)孔(kong)纖維(wei)的(de)含量(liang)(liang)也沒(mei)有具體要(yao)求(qiu),據說實(shi)際含量(liang)(liang)是(shi)多(duo)(duo)少,是(shi)0%,還是(shi)10%到100%都可稱為七孔(kong)或九(jiu)孔(kong)枕(zhen),市場甚至出現了11孔(kong),12孔(kong)枕(zhen)頭(tou)。“七孔(kong)棉(mian)”、“九(jiu)孔(kong)棉(mian)”,其實(shi)這些產(chan)品(pin)都應(ying)當稱為“滌(di)綸纖維(wei)”和(he)“棉(mian)”根本不沾邊。關于(yu)所(suo)謂(wei)“孔(kong)的(de)”數量(liang)(liang),更是(shi)無從考究,《枕(zhen)頭(tou)記》引用中國纖維(wei)行業(ye)權威(wei)儀征(zheng)化(hua)(hua)(hua)纖的(de)介紹,目(mu)前(qian)技術(shu)最(zui)先進的(de)儀征(zheng)化(hua)(hua)(hua)纖工廠僅(jin)僅(jin)生(sheng)產(chan)一孔(kong)的(de)中空(kong)纖維(wei),不存在七孔(kong)或者九(jiu)孔(kong)纖維(wei),市場上面多(duo)(duo)數七孔(kong)或者九(jiu)孔(kong)纖維(wei)均系中空(kong)棉(mian)。
