纖維被七孔被知識普及 七孔被是什么

常聽人們說(shuo)什么“七孔(kong)(kong)(kong)被(bei)(bei)(bei)”、“九(jiu)孔(kong)(kong)(kong)被(bei)(bei)(bei)”，究(jiu)竟這“七孔(kong)(kong)(kong)”、“九(jiu)孔(kong)(kong)(kong)”是何意(yi)思呢？原來(lai)，這說(shuo)的(de)是“纖(xian)維(wei)被(bei)(bei)(bei)”的(de)不同分類。纖(xian)維(wei)被(bei)(bei)(bei)又被(bei)(bei)(bei)稱為“太空棉”，是用(yong)滌綸、人造(zao)纖(xian)維(wei)等(deng)物質(zhi)做成，“孔(kong)(kong)(kong)”指的(de)是一條(tiao)纖(xian)維(wei)中(zhong)的(de)空芯(xin)部位，孔(kong)(kong)(kong)前面(mian)的(de)數(shu)字表示所使用(yong)的(de)纖(xian)維(wei)中(zhong)空芯(xin)的(de)個(ge)數(shu)。市面(mian)上的(de)纖(xian)維(wei)被(bei)(bei)(bei)主要(yao)分為四孔(kong)(kong)(kong)、七孔(kong)(kong)(kong)和(he)九(jiu)孔(kong)(kong)(kong)三種，品(pin)質(zhi)的(de)評定一般由孔(kong)(kong)(kong)數(shu)來(lai)分，孔(kong)(kong)(kong)數(shu)越多(duo)的(de)被(bei)(bei)(bei)子透(tou)氣(qi)性越高，品(pin)質(zhi)越佳。

七孔九孔棉概念(nian)科學認識(shi)：

所(suo)謂“七(qi)孔(kong)棉(mian)”、“九(jiu)(jiu)孔(kong)棉(mian)”其(qi)實(shi)是(shi)(shi)(shi)化(hua)纖(xian)，帶孔(kong)的(de)棉(mian)被內芯(xin)都不(bu)是(shi)(shi)(shi)棉(mian)，而是(shi)(shi)(shi)化(hua)纖(xian)產(chan)品。國家目前對多(duo)空(kong)(kong)枕頭(tou)并沒(mei)有標準，對多(duo)孔(kong)纖(xian)維(wei)的(de)含量也沒(mei)有具體(ti)要求，據(ju)說實(shi)際含量是(shi)(shi)(shi)多(duo)少，是(shi)(shi)(shi)0%，還是(shi)(shi)(shi)10%到100%都可稱為七(qi)孔(kong)或九(jiu)(jiu)孔(kong)枕，市場甚(shen)至出現了11孔(kong)，12孔(kong)枕頭(tou)。“七(qi)孔(kong)棉(mian)”、“九(jiu)(jiu)孔(kong)棉(mian)”，其(qi)實(shi)這些產(chan)品都應當(dang)稱為“滌(di)綸纖(xian)維(wei)”和“棉(mian)”根(gen)本(ben)不(bu)沾邊。關于所(suo)謂“孔(kong)的(de)”數量，更是(shi)(shi)(shi)無(wu)從考(kao)究，《枕頭(tou)記》引(yin)用中(zhong)國纖(xian)維(wei)行業權威儀征化(hua)纖(xian)的(de)介(jie)紹，目前技術最先進的(de)儀征化(hua)纖(xian)工(gong)廠僅僅生產(chan)一(yi)孔(kong)的(de)中(zhong)空(kong)(kong)纖(xian)維(wei)，不(bu)存(cun)在(zai)七(qi)孔(kong)或者九(jiu)(jiu)孔(kong)纖(xian)維(wei)，市場上(shang)面多(duo)數七(qi)孔(kong)或者九(jiu)(jiu)孔(kong)纖(xian)維(wei)均系中(zhong)空(kong)(kong)棉(mian)。
