</p> <p> <br /> </p> <p> 2. 3退漿 </p> <p> 紡織廠為了順利的織布,往往對經(jīng)紗_上漿以提**力和耐磨性。坯布上的漿料即影響織物的吸水性能，還影響染整產(chǎn)品的質(zhì)量，紹興液氨絲光棉,且會增加染化藥品的消耗，故在煮練前應(yīng)先去除漿料,這個過程叫退漿。 </p> <p> 織物上的漿料通常為PVA淀粉漿，它的特點是易溶于80C以上的熱水中,所以在煮練前可以***大部分的漿料, PVA漿料是很難降解的且容易造成環(huán)境污染,熱水退掉的漿料可以集中收集起來進行回收利用，回收后的PVA可以繼續(xù)用在織布工廠，紹興液氨絲光棉，PVA回收裝置即可減輕污水處理壓力又能節(jié)省成本，紹興液氨絲光棉。 </p> <p> <br /> </p> <p> <br

src="https://tyunfile.71360.com/UploadFile/shhyfztg/637322353590673828/4603973.png"></div><p> 根據(jù)（1）式 </p> <p> （1）當(dāng)C2不是很大時，C2↑，C1↑，P↑，溶脹↑ </p> <p> （2）若有鹽存在，膜外[Na ]↑,即X1↑，P↓，溶脹↓ </p> <p> （3）若C2↑↑，C1相對C2很小，而膜外[Na ]↑↑，X‘很大，P→O </p> <p> <br /> </p> <p> <br /> </p> <p> §3、絲光工藝條件分析 </p> <p> 絲光工藝的基本條件是NaOH溶液的濃度，溫度，作用時間，張力和去堿。 </p> <p> 一、堿液濃度 </p> <p> 是影響絲光效果的主要因素 </p> <p> ① 棉纖維用不同濃度燒堿溶液處理后，長度和直徑的變化情況： </p> <p> 濃度＞8%，直徑增加，長度縮短至比較大 </p> <p> ②棉紗在不同濃度NaOH溶液中的收縮和染著力 </p> <p> ③棉布絲光對濃度要求(C與收縮及鋇值關(guān)系) </p> <p> C=177g/L時，鋇值為150，C=245g/l，鋇值比較高。 </p> <p> C=240~280g/l，收縮趨于穩(wěn)定。 </p> <p> 因此絲光**適宜的燒堿濃度是245g/l左右，考慮到織物本身吸堿、空氣中酸性氣體的耗堿等因素，棉布絲光堿濃度為260～280g/l。實際生產(chǎn)中，可根據(jù)半制品的品質(zhì)和成品的質(zhì)量要求選擇。紹興液氨絲光棉實際上兩者整理工藝的機理和效果并不相同。</p><div

<p> 物理性能 </p> <p> ①絲光棉光澤比純棉好(經(jīng)過絲光處理后表面光滑,對光的漫反射現(xiàn)象少) ; </p> <p> ②絲光棉強度比純棉高(天然扭曲消失,纖維之間排列緊密、抱合力增加) ; </p> <p> ③絲光棉的尺寸穩(wěn)定性比純棉好(纖維素分子重新排列,原內(nèi)應(yīng)力消除)。 </p> <p> 化學(xué)性能 </p> <p> ①絲光棉反應(yīng)性提高(無定形區(qū)增加,羥基隨主價健的旋轉(zhuǎn)而由不可及變?yōu)榭杉? ; </p> <p> ②絲光棉對水、碘、氫氧化鋇和染料的吸附量比純棉大。 </p> <p> <br /> </p> <p> <br /> </p> </p> <p> <br /> </p><p> 3、分子結(jié)構(gòu)的變化 </p> <p> 棉纖維在濃堿液中發(fā)生溶脹后，大分子鏈間的氫鍵被拆散，舒解了織物中貯存的內(nèi)應(yīng)力，通過拉伸，大分子進行取向排列，在新的位置上建立起新的分子鍵，且分子間力比溶脹前大。***在張力下去堿，已取向排列的纖維間的氫鍵被固定下來(是在更為自然，穩(wěn)定的狀態(tài)下被固定下來的)，這時的纖維處于較低的能量狀態(tài)，因此尺寸穩(wěn)定。 </p> <p> <br /> </p> <p> 二、絲光原理 </p> <p> <br /> </p> <p> 絲光是一個復(fù)雜的過程，關(guān)于棉纖維在濃堿液中發(fā)生劇烈溶脹的原因有兩種理論作出解釋 </p> <p> <br /> </p> <p> 1、水合理論 </p> <p> (1)燒堿與天然纖維素(纖維素)作用，生成堿纖維素，主要有兩種類型： </p> <p> ①醇化合物： </p> <p> ②分子化合物(加成化合物)： </p> <p> 兩種產(chǎn)物都不穩(wěn)定，經(jīng)水洗便水解成水合纖維素，再通過脫水烘干后即成為絲光纖維素(纖維素Ⅱ)整個 </p> <p> <br /> 我們有可能看到“液氨整理”的字樣。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

(2)棉纖維經(jīng)濃NaOH處理發(fā)生劇烈的不可逆溶脹原因是：鈉離子體積小，它可以進入到fibre的晶區(qū)；同時Na 是一種水化能力很強的離子，環(huán)繞在一個Na 周圍的水分子多達(dá)66個之多，以至形成一個水化層，當(dāng)Na 進入fibre內(nèi)部并與fibre結(jié)合時，大量的水分也被帶入，因而引起了劇烈溶脹，由于能進入晶區(qū)，因此，溶脹是不可逆的。 </p> <p> (3)這種溶脹受溫度的影響： </p> <p> （4）溶脹也受NaOH濃度及中性鹽的影響， </p> <p> <br /> </p> <p> 2、Donnen膜平衡理論 </p> <p> 溶脹是滲透壓作用的結(jié)果。 </p> <p> 假設(shè)纖維素是一種弱堿，在燒堿溶液中可形成鈉鹽，纖維素鈉鹽電離生成不可移動的纖維素陰離子Cell-O?，溶液中尚有可移動的Na 和OH-，如果有NaCl存在，還有Cl?，將纖維表面看作有類似半透膜性質(zhì)，這些離子按一定條件分布，達(dá)到平衡時，膜內(nèi)外必須分別達(dá)到電性中和。 </p> <p> 膜內(nèi)可移動離子總濃度： CI=[Na ]I [OH-]I [Cl-]I=2X-C1 </p> <p> 膜外可移動離子總濃度： CO=2(C2 C3-X)=2X， </p> <p> CI>CO，因而產(chǎn)生了滲透壓（P），引起纖維溶脹。 </p> <p> P=RT（CI-CO）=RT(2X-C1-2X′) </p> <p> P=RT() （1）工藝過程簡捷,節(jié)省能源。清遠(yuǎn)生產(chǎn)液氨絲光棉</p><p

紗線絲光:指棉紗線在有張力的情況下,經(jīng)過高濃度燒堿或經(jīng)液氨處理,使其既具有棉原有的特性，又具有絲一般光澤的一類特殊的棉紗線。 </p> <p> 織物絲光:指棉面料在有張力的情況下,經(jīng)過高濃度燒堿或經(jīng)液氨處理,使面料光澤度更佳、更挺括、保形性更好。 </p> <p> 雙絲光是指用經(jīng)過絲光的棉紗線制織成織物,然后再對其織物進行絲光,使棉纖維在濃堿中發(fā)生充分、不可逆的溶脹,經(jīng)處理后的織物表面光潔,具有絲綢般的光澤,而且強力、抗起毛起球性、尺寸穩(wěn)定性等均有不同程度的提高。 </p> <p> <br /> </p> <p> <br /> 紹興液氨絲光棉</p><p
