纖維被七孔被知識普及 七孔被是什么

常(chang)聽(ting)人們說什么“七孔(kong)(kong)(kong)(kong)被(bei)(bei)(bei)”、“九(jiu)孔(kong)(kong)(kong)(kong)被(bei)(bei)(bei)”，究竟這(zhe)“七孔(kong)(kong)(kong)(kong)”、“九(jiu)孔(kong)(kong)(kong)(kong)”是何意思呢？原來(lai)，這(zhe)說的(de)(de)(de)是“纖(xian)維(wei)被(bei)(bei)(bei)”的(de)(de)(de)不(bu)同分(fen)類。纖(xian)維(wei)被(bei)(bei)(bei)又被(bei)(bei)(bei)稱為“太空棉”，是用(yong)(yong)滌綸、人造纖(xian)維(wei)等物質(zhi)(zhi)做成，“孔(kong)(kong)(kong)(kong)”指的(de)(de)(de)是一條纖(xian)維(wei)中(zhong)的(de)(de)(de)空芯部位，孔(kong)(kong)(kong)(kong)前(qian)面的(de)(de)(de)數(shu)(shu)字表示所使用(yong)(yong)的(de)(de)(de)纖(xian)維(wei)中(zhong)空芯的(de)(de)(de)個數(shu)(shu)。市(shi)面上的(de)(de)(de)纖(xian)維(wei)被(bei)(bei)(bei)主要分(fen)為四孔(kong)(kong)(kong)(kong)、七孔(kong)(kong)(kong)(kong)和九(jiu)孔(kong)(kong)(kong)(kong)三種，品質(zhi)(zhi)的(de)(de)(de)評定一般(ban)由孔(kong)(kong)(kong)(kong)數(shu)(shu)來(lai)分(fen)，孔(kong)(kong)(kong)(kong)數(shu)(shu)越多的(de)(de)(de)被(bei)(bei)(bei)子(zi)透氣性越高，品質(zhi)(zhi)越佳(jia)。

七孔九孔棉概(gai)念科學認識(shi)：

所(suo)謂“七(qi)孔(kong)(kong)棉(mian)”、“九(jiu)(jiu)孔(kong)(kong)棉(mian)”其實(shi)是(shi)化(hua)纖(xian)，帶孔(kong)(kong)的(de)(de)棉(mian)被內芯都不是(shi)棉(mian)，而(er)是(shi)化(hua)纖(xian)產(chan)(chan)品。國家目前對多(duo)(duo)(duo)空(kong)枕(zhen)頭(tou)并沒有標準，對多(duo)(duo)(duo)孔(kong)(kong)纖(xian)維(wei)的(de)(de)含(han)量(liang)也(ye)沒有具體要(yao)求，據說實(shi)際含(han)量(liang)是(shi)多(duo)(duo)(duo)少，是(shi)0%，還(huan)是(shi)10%到100%都可稱為(wei)七(qi)孔(kong)(kong)或九(jiu)(jiu)孔(kong)(kong)枕(zhen)，市場(chang)(chang)甚至出現(xian)了11孔(kong)(kong)，12孔(kong)(kong)枕(zhen)頭(tou)。“七(qi)孔(kong)(kong)棉(mian)”、“九(jiu)(jiu)孔(kong)(kong)棉(mian)”，其實(shi)這(zhe)些產(chan)(chan)品都應當稱為(wei)“滌綸(lun)纖(xian)維(wei)”和“棉(mian)”根本不沾邊(bian)。關于所(suo)謂“孔(kong)(kong)的(de)(de)”數量(liang)，更是(shi)無從考究，《枕(zhen)頭(tou)記(ji)》引用(yong)中(zhong)國纖(xian)維(wei)行業權(quan)威儀征(zheng)化(hua)纖(xian)的(de)(de)介紹(shao)，目前技術最(zui)先進的(de)(de)儀征(zheng)化(hua)纖(xian)工廠(chang)僅僅生產(chan)(chan)一孔(kong)(kong)的(de)(de)中(zhong)空(kong)纖(xian)維(wei)，不存在七(qi)孔(kong)(kong)或者九(jiu)(jiu)孔(kong)(kong)纖(xian)維(wei)，市場(chang)(chang)上面多(duo)(duo)(duo)數七(qi)孔(kong)(kong)或者九(jiu)(jiu)孔(kong)(kong)纖(xian)維(wei)均(jun)系中(zhong)空(kong)棉(mian)。
