雙層(ceng)(ceng)織(zhi)(zhi)物一般采用(yong)雙織(zhi)(zhi)軸織(zhi)(zhi)機(ji)生(sheng)(sheng)產,而單(dan)織(zhi)(zhi)軸織(zhi)(zhi)機(ji)只(zhi)能生(sheng)(sheng)產浮(fu)長(chang)線差別較(jiao)小的雙層(ceng)(ceng)織(zhi)(zhi)物。雙層(ceng)(ceng)織(zhi)(zhi)物分(fen)表(biao)(biao)(biao)層(ceng)(ceng)和(he)里(li)層(ceng)(ceng),一般由接結經將兩層(ceng)(ceng)相(xiang)連。根據表(biao)(biao)(biao)層(ceng)(ceng)里(li)層(ceng)(ceng)的組織(zhi)(zhi)特點和(he)接結方(fang)法,表(biao)(biao)(biao)里(li)經紗(sha)與接結經紗(sha)的浮(fu)長(chang)線存在(zai)差異(yi)(yi);當(dang)浮(fu)長(chang)線差異(yi)(yi)較(jiao)小時,所(suo)受(shou)張(zhang)力趨于一致,可(ke)以采用(yong)單(dan)織(zhi)(zhi)軸織(zhi)(zhi)機(ji)生(sheng)(sheng)產;當(dang)浮(fu)長(chang)線差異(yi)(yi)較(jiao)大時,所(suo)受(shou)張(zhang)力相(xiang)差就較(jiao)大, 適宜(yi)采用(yong)雙織(zhi)(zhi)軸織(zhi)(zhi)機(ji)生(sheng)(sheng)產。

根據雙(shuang)層織(zhi)(zhi)(zhi)(zhi)物自(zi)身的(de)組(zu)織(zhi)(zhi)(zhi)(zhi)特點,一般表經(jing)(jing)(jing)(jing)紗(sha)(sha)的(de)交織(zhi)(zhi)(zhi)(zhi)點和屈曲(qu)比里(li)(li)經(jing)(jing)(jing)(jing)紗(sha)(sha)的(de)多(duo)(duo),張(zhang)(zhang)力也大;接(jie)結(jie)經(jing)(jing)(jing)(jing)的(de)交織(zhi)(zhi)(zhi)(zhi)點最(zui)少,所受(shou)張(zhang)(zhang)力最(zui)小。織(zhi)(zhi)(zhi)(zhi)造(zao)過(guo)程中,經(jing)(jing)(jing)(jing)紗(sha)(sha)前(qian)(qian)后分配特點是(shi):交織(zhi)(zhi)(zhi)(zhi)點多(duo)(duo)、張(zhang)(zhang)力大的(de)經(jing)(jing)(jing)(jing)紗(sha)(sha)分配在(zai)(zai) 前(qian)(qian)幾(ji)(ji)頁綜框上(shang)(shang)(shang)(shang),交織(zhi)(zhi)(zhi)(zhi)點少、張(zhang)(zhang)力小的(de)經(jing)(jing)(jing)(jing)紗(sha)(sha)分配在(zai)(zai)后幾(ji)(ji)頁綜框上(shang)(shang)(shang)(shang)。因此,表經(jing)(jing)(jing)(jing)紗(sha)(sha)多(duo)(duo)在(zai)(zai)前(qian)(qian)幾(ji)(ji)頁綜框上(shang)(shang)(shang)(shang),里(li)(li)經(jing)(jing)(jing)(jing)紗(sha)(sha)多(duo)(duo)在(zai)(zai)后幾(ji)(ji)頁綜框上(shang)(shang)(shang)(shang),接(jie)結(jie)經(jing)(jing)(jing)(jing)在(zai)(zai)最(zui)后的(de)幾(ji)(ji)頁綜框上(shang)(shang)(shang)(shang)。這種(zhong)穿綜方法(fa)造(zao)成(cheng)生(sheng)產中接(jie)結(jie)經(jing)(jing)(jing)(jing)越織(zhi)(zhi)(zhi)(zhi)越松(song),織(zhi)(zhi)(zhi)(zhi)造(zao)一定(ding)時間后停經(jing)(jing)(jing)(jing)片會(hui)下沉,最(zui)終(zhong)導致織(zhi)(zhi)(zhi)(zhi)機 開口不清,甚至(zhi)經(jing)(jing)(jing)(jing)停、無法(fa)開車(che)。由于(yu)表里(li)(li)組(zu)織(zhi)(zhi)(zhi)(zhi)結(jie)構的(de)確(que)定(ding)性,故松(song)緊經(jing)(jing)(jing)(jing)紗(sha)(sha)的(de)釋放(fang)比例(li)是(shi)確(que)定(ding)的(de),不會(hui)隨(sui)著(zhu)織(zhi)(zhi)(zhi)(zhi)造(zao)的(de)進行而無限松(song)弛(chi)。

通過(guo)(guo)分析可(ke)(ke)知：造(zao)成無法開(kai)車的(de)根本原(yuan)因(yin)(yin)(yin)是接(jie)(jie)(jie)結經(jing)(jing)(jing)松弛,使停(ting)(ting)經(jing)(jing)(jing)片(pian)下(xia)降,導致(zhi)停(ting)(ting)車;去掉接(jie)(jie)(jie)結經(jing)(jing)(jing)上的(de)停(ting)(ting)經(jing)(jing)(jing)片(pian),織造(zao)可(ke)(ke)以(yi)順利進(jin)行。但(dan)去掉接(jie)(jie)(jie)結經(jing)(jing)(jing)上的(de)停(ting)(ting)經(jing)(jing)(jing)片(pian)也存(cun)在(zai)隱患(huan),即不(bu)易及(ji)時發現接(jie)(jie)(jie)結經(jing)(jing)(jing)斷(duan)(duan)裂。經(jing)(jing)(jing)紗(sha)斷(duan)(duan)裂原(yuan)因(yin)(yin)(yin)主(zhu)要(yao)有經(jing)(jing)(jing)紗(sha)張力過(guo)(guo)大(da)被(bei)拉(la)斷(duan)(duan),經(jing)(jing)(jing)紗(sha)被(bei)綜(zong)絲、停(ting)(ting)經(jing)(jing)(jing)片(pian)的(de)毛刺掛斷(duan)(duan),漿紗(sha)不(bu)良(liang)造(zao)成漿斑黏(nian)連(lian)斷(duan)(duan)經(jing)(jing)(jing),整經(jing)(jing)(jing)和漿紗(sha)時接(jie)(jie)(jie)頭不(bu)良(liang)導致(zhi)斷(duan)(duan)經(jing)(jing)(jing)等。其中,以(yi)經(jing)(jing)(jing)紗(sha)張力過(guo)(guo)大(da)被(bei)拉(la)斷(duan)(duan)為主(zhu)要(yao)原(yuan)因(yin)(yin)(yin)。 因(yin)(yin)(yin)此,在(zai)接(jie)(jie)(jie)結經(jing)(jing)(jing)不(bu)穿(chuan)停(ting)(ting)經(jing)(jing)(jing)片(pian)的(de)情況下(xia),一(yi)般(ban)也可(ke)(ke)實(shi) 現順利織造(zao)。

為預防(fang)接(jie)結經(jing)發生斷經(jing)現象,應(ying)加強(qiang)擋(dang)車(che)工(gong)巡(xun)回檢查布面(mian)工(gong)作;在整經(jing)、漿紗時可(ke)穿(chuan)分(fen)絞(jiao)線, 對接(jie)結經(jing)染色等(deng),使擋(dang)車(che)工(gong)較容易發現斷經(jing);在采 用(yong)分(fen)區穿(chuan)綜的(de)同時,可(ke)以考(kao)慮變化鋼筘穿(chuan)入(ru)數(shu),改善接(jie)結經(jing)松(song)弛現象等(deng)。總(zong)之,接(jie)結經(jing)斷裂的(de)幾率(lv)不高,特(te)別是在生產(chan)粗號、股線、高強(qiang)經(jing)紗等(deng)雙層織物(wu)時,可(ke)放心(xin)使用(yong)該方法進行生產(chan),從而避免(mian)因接(jie)結經(jing)松(song)弛導致的(de)停車(che)。
