保暖性復(fù)合織物層壓工藝與性能的探討研究.pdf

1、摘要層壓復(fù)合織物是將多層不同性能風(fēng)格的面料組合在一起，使各層織物功能疊加、取長補(bǔ)短，達(dá)到多樣化和舒適化的要求。因而，多層復(fù)合織物的研究已成為人們關(guān)注的重要方向。本課題主要做了以下幾方面的研究。(1)根據(jù)要研究的復(fù)合織物的功能要求，設(shè)計(jì)復(fù)合問層次。(2)選購面料和罩料，測試其經(jīng)緯密、厚度和平方米克重，并與工廠提供的復(fù)合織物進(jìn)行對(duì)比分析。選購兩種不同厚度的微孔PTFE薄膜，并對(duì)功能薄膜的材質(zhì)和化學(xué)成分進(jìn)行紅外光譜分析；采用掃描電鏡觀察PTF

2、E薄膜的內(nèi)部形態(tài)結(jié)構(gòu)。粘合劑分別選用聚氨酯和EVA兩種熱熔膠。(3)利用正交試驗(yàn)設(shè)計(jì)組合方案，具體采用L9(34)正交表，得出9種層壓復(fù)合工藝。從而將24種組合方式層壓成108種兩層復(fù)合織物，108種三層復(fù)合織物，共216種不同的復(fù)合織物。(4)在不同工藝參數(shù)條件下，主要測試了層壓復(fù)合織物的剝離強(qiáng)度、耐靜水壓、透濕和透氣等性能，并分別對(duì)其進(jìn)行研究分析?？傮w上，用灰色近優(yōu)理論來綜合評(píng)定復(fù)合的最優(yōu)工藝，主要從層壓復(fù)合織物的各個(gè)主要性能來進(jìn)行

3、綜合的考核、評(píng)定，通過計(jì)算，最終得出工藝5為最優(yōu)工藝。(5)測試在最優(yōu)工藝5條件下復(fù)合成的織物保暖性，運(yùn)用織物保溫率與織物結(jié)構(gòu)參數(shù)間的擬合曲線，分析得出織物的保溫率與織物的厚度、緊度和平方米克重三個(gè)結(jié)構(gòu)參數(shù)成正增長關(guān)系。關(guān)鍵詞：復(fù)合織物；層壓工藝；保暖性；性能指標(biāo)WarmthCompoundFabricLaminatedProcessandPropertyResearchAbstractLaminatedcompositefabrici
