纖維被七孔被知識普及 七孔被是什么

常聽人(ren)們說什么“七孔(kong)(kong)被(bei)(bei)”、“九(jiu)孔(kong)(kong)被(bei)(bei)”，究(jiu)竟這“七孔(kong)(kong)”、“九(jiu)孔(kong)(kong)”是(shi)(shi)何(he)意(yi)思呢(ni)？原來(lai)，這說的(de)是(shi)(shi)“纖(xian)(xian)維(wei)被(bei)(bei)”的(de)不同分類。纖(xian)(xian)維(wei)被(bei)(bei)又被(bei)(bei)稱為“太空棉”，是(shi)(shi)用(yong)滌綸、人(ren)造(zao)纖(xian)(xian)維(wei)等(deng)物質做成(cheng)，“孔(kong)(kong)”指的(de)是(shi)(shi)一(yi)條(tiao)纖(xian)(xian)維(wei)中的(de)空芯部位，孔(kong)(kong)前(qian)面(mian)的(de)數字表示(shi)所(suo)使用(yong)的(de)纖(xian)(xian)維(wei)中空芯的(de)個(ge)數。市面(mian)上的(de)纖(xian)(xian)維(wei)被(bei)(bei)主要分為四孔(kong)(kong)、七孔(kong)(kong)和(he)九(jiu)孔(kong)(kong)三(san)種，品質的(de)評定一(yi)般(ban)由孔(kong)(kong)數來(lai)分，孔(kong)(kong)數越多的(de)被(bei)(bei)子透(tou)氣性(xing)越高，品質越佳。

七孔九孔棉(mian)概念科學認識：

所(suo)謂(wei)“七(qi)(qi)(qi)孔(kong)(kong)(kong)棉”、“九(jiu)孔(kong)(kong)(kong)棉”其實是化(hua)纖(xian)(xian)(xian)，帶孔(kong)(kong)(kong)的(de)棉被(bei)內芯都(dou)(dou)不(bu)是棉，而是化(hua)纖(xian)(xian)(xian)產品。國家目(mu)前(qian)對多空枕(zhen)頭并(bing)沒(mei)有標準，對多孔(kong)(kong)(kong)纖(xian)(xian)(xian)維(wei)(wei)的(de)含量(liang)(liang)也沒(mei)有具(ju)體要求(qiu)，據說實際含量(liang)(liang)是多少，是0%，還(huan)是10%到100%都(dou)(dou)可稱為(wei)七(qi)(qi)(qi)孔(kong)(kong)(kong)或(huo)九(jiu)孔(kong)(kong)(kong)枕(zhen)，市(shi)場甚至出現了11孔(kong)(kong)(kong)，12孔(kong)(kong)(kong)枕(zhen)頭。“七(qi)(qi)(qi)孔(kong)(kong)(kong)棉”、“九(jiu)孔(kong)(kong)(kong)棉”，其實這些產品都(dou)(dou)應當(dang)稱為(wei)“滌綸纖(xian)(xian)(xian)維(wei)(wei)”和“棉”根本(ben)不(bu)沾邊。關于所(suo)謂(wei)“孔(kong)(kong)(kong)的(de)”數(shu)量(liang)(liang)，更是無從(cong)考究，《枕(zhen)頭記》引用(yong)中(zhong)國纖(xian)(xian)(xian)維(wei)(wei)行業權威(wei)儀征(zheng)化(hua)纖(xian)(xian)(xian)的(de)介紹，目(mu)前(qian)技(ji)術最先進的(de)儀征(zheng)化(hua)纖(xian)(xian)(xian)工(gong)廠(chang)僅僅生產一孔(kong)(kong)(kong)的(de)中(zhong)空纖(xian)(xian)(xian)維(wei)(wei)，不(bu)存在七(qi)(qi)(qi)孔(kong)(kong)(kong)或(huo)者(zhe)九(jiu)孔(kong)(kong)(kong)纖(xian)(xian)(xian)維(wei)(wei)，市(shi)場上(shang)面多數(shu)七(qi)(qi)(qi)孔(kong)(kong)(kong)或(huo)者(zhe)九(jiu)孔(kong)(kong)(kong)纖(xian)(xian)(xian)維(wei)(wei)均系中(zhong)空棉。
