永吉安（廈(sha)門）消防(fang)科技有限公司(si)是一家集消防(fang)逃(tao)生(sheng)設備的(de)研發，生(sheng)產(chan)，銷售于一體的(de)化公司(si)，陽泉緩降(jiang)(jiang)(jiang)器(qi)，主要經營：逃(tao)生(sheng)緩降(jiang)(jiang)(jiang)器(qi)，救生(sheng)緩降(jiang)(jiang)(jiang)器(qi)，高樓緩降(jiang)(jiang)(jiang)器(qi)，高空緩降(jiang)(jiang)(jiang)器(qi)，消防(fang)緩降(jiang)(jiang)(jiang)器(qi)，高空緩降(jiang)(jiang)(jiang)器(qi)，繩索(suo)緩降(jiang)(jiang)(jiang)器(qi)等。

磚(zhuan)制建筑物倒塌(ta)時(shi)會(hui)散落(luo)成(cheng)零(ling)碎(sui)的磚(zhuan)塊，這(zhe)往往會(hui)造(zao)成(cheng)很多傷害，但是卻不會(hui)像(xiang)混凝土建筑那樣壓碎(sui)人的身體。3.如果坍塌(ta)發生(sheng)時(shi)你正躺在(zai)床(chuang)上，只要(yao)滾到床(chuang)下就可以了，因為床(chuang)的周圍會(hui)存在(zai)安全的生(sheng)存空間。

紡織(zhi)用毛類(lei)纖(xian)維(wei)中，用量多。毛纖(xian)維(wei)的(de)主要組成(cheng)物質為不溶性蛋(dan)白質，稱為角蛋(dan)白。

羊毛(mao)(mao)的(de)細(xi)(xi)度與它的(de)各項物(wu)理(li)性質都(dou)有密切的(de)聯系。一般來說，羊毛(mao)(mao)越(yue)細(xi)(xi)，其細(xi)(xi)度就越(yue)均勻，強度越(yue)高，天然卷曲多，高空緩降器(qi)，鱗片(pian)密，光澤柔(rou)和(he)脂肪含(han)量(liang)高，但(dan)長度偏短。細(xi)(xi)度是決(jue)定(ding)羊毛(mao)(mao)品質好(hao)壞的(de)重要指標。細(xi)(xi)度細(xi)(xi)有利于成紗強力和(he)成紗條干及成紗線密度，能(neng)織(zhi)制精紡毛(mao)(mao)織(zhi)物(wu)，使織(zhi)物(wu)表面光潔，紋路清晰，手感滑爽。

蠶絲

蠶(can)絲的主(zhu)要(yao)組(zu)成物質是(shi)絲朊(ruan)，也是(shi)一種蛋白質所以與羊(yang)(yang)毛纖維相似，但耐(nai)酸(suan)性較羊(yang)(yang)毛差，是(shi)較耐(nai)弱酸(suan)而不耐(nai)堿(jian)。

蠶絲具(ju)有其他纖維所不能比擬(ni)的美麗光(guang)澤，優(you)雅悅(yue)目。
