如本文所使用,術語「膜」意指扁平、通常二維的物品。膜可為自撐式,諸如已鑄造及乾燥或擠壓之膜。可替代地,膜可為熔融物、分散體或溶液。
如本文所使用,術語「分散體」係指一個系統,其中分散相由細粉狀顆粒組成,且連續相可為液體、固體或氣體。
如本文所使用,術語「水性聚胺基甲酸酯分散體」係指一種已分散於水性介質、諸如水(包括去離子水)中之含有至少一種聚胺基甲酸酯或聚胺基甲酸酯脲聚合物或預聚物(諸如本文所述之聚胺基甲酸酯預聚物)、視情況包括溶劑的組合物。
如本文所使用,除非另外規定,否則術語「溶劑」係指一種非水介質,其中非水介質包括有機溶劑,包括揮發性有機溶劑(諸如丙酮)及稍微不太揮發的有機溶劑(諸如MEK或NMP)。

如本文所使用,術語「織物」係指一種針織、編織或非編織材料。針織物可為橫針織物、圓形針織物、經編針織物、窄幅彈性織物及花邊。編織物可具有任何結構,例如緞紋、斜紋、平紋編織、牛津布編織、籃式編織及窄幅彈性織物。非編織材料可為熔噴、紡黏、濕式佈層、基於粗梳纖維的短纖維網及其類似物。「織物」意欲包括吸收性織物。
如本文所使用,術語「衍生自」係指自另一物件形成一種物質。舉例而言,膜可衍生自可經乾燥的分散體。
一些態樣之拋棄式個人護理用品有利地建構成在特定部位具有織物複合物區域以提供拉伸回復性。如本文所使用,術語『織物複合物』較佳包含例如應用於吸收性織物之彈性聚合物組合物,其既具有吸收性且呈現拉伸回復性。在不受任何特定理論束縛之情況下,咸信彈性聚合物組合物之聚合物顆粒不連續地定位且與纖維及紗黏著,並分開穿透入織物主體。
彈性體纖維通常用於提供織物及服裝之拉伸及彈性回復。「彈性體纖維」為連續長絲(視情況凝集複絲)或不含稀釋劑之複數個長絲,其具有與任何捲曲無關之超過100%的斷裂伸長率。彈性體纖維在(1)拉伸至其兩倍長度;(2)保持一分鐘;及(3)釋放時,在經釋放的一分鐘內回縮至小於其原始長度的1.5倍。如本說明書之本文所用,「彈性體纖維」意指至少一種彈性體纖維或長絲。此類彈性體纖維包括(但不限於)橡膠長絲、雙組成長絲(其可基於橡膠、聚胺基甲酸酯等)、雷斯托(lastol)及彈性人造纖維(spandex)。術語「彈性體」及「彈性」在本說明書通篇中可互換使用。
「彈性人造纖維」為製造之長絲,其中長絲形成物質為包含至少85重量%之嵌段聚胺基甲酸酯的長鏈合成聚合物。「彈性酯」為製造之長絲,其中纖維形成物質為由至少50重量%之脂族聚醚及至少35重量%之聚酯組成的長鏈合成聚合物。儘管非彈性體,但在本文中彈性酯可包括於一些織物中。
「聚酯雙組分長絲」意指包含一對沿纖維之長度彼此緊密黏附之聚酯的連續長絲,以使得纖維橫截面為例如並列、偏心皮芯或可自其發展有用捲曲之其他適合之橫截面。聚酯雙組分長絲包含聚(對苯二甲酸丙二酯)及至少一種選自由聚(對苯二甲酸乙二酯)、聚(對苯二甲酸丙二酯)及聚(對苯二甲酸丁二酯)組成之群的聚合物或此類成員之組合,其具有約10%至
約80%之熱定型後的捲曲收縮值。
根據本發明,彈性聚合物組合物可包含經聚合物塗佈之拉伸非織物或經聚合物塗佈之拉伸膜。
用於此等彈性聚合物組合物之拉伸非織物的實例包括(但不限於)聚丙烯、聚乙烯、聚對苯二甲酸乙二酯及其組合或摻合物。
膜實例包括(但不限於)單一溶液聚胺基甲酸酯、聚胺基甲酸酯之衍生物、乳膠NRL、聚矽氧及固化的其他組合物。膜厚度在約0.5密耳至約5密耳之範圍內。
用於彈性聚合物組合物之聚合物塗層的實例包括(但不限於)聚胺基甲酸酯、乳膠或橡膠溶液及苯乙烯嵌段共聚物及其組合或摻合物。
本發明之彈性聚合物組合物呈現約5%至約2000%之伸長率。在一個非限制性實施例中,當彈性聚合物組合物為經聚合物塗佈之拉伸非織物時,其呈現約5%至約200%的伸長率。在一替代非限制性實施例中,當彈性聚合物組合物為經聚合物塗佈之膜時,其呈現約400%至約2000%的伸長率。
本發明之彈性聚合物組合物可應用於吸收性織物以提供拉伸回復性。不同於先前技術中之膜或織物層壓物,在創新織物內,聚合物組合物未形成膜或連續性平坦表面。當使用分散體時,粉狀聚合物顆粒不連續地置放且分開穿透入織物主體,由此避免任何不合意光亮及/或橡膠接觸面。彈性聚合物組合物在由組合物製造之任何產品的外部亦不可見且產品呈現良好的透氣性。
彈性聚合物組合物可藉由多種方法分散,包括(但不限於)熱/黏合、擴散、塗刷、刷塗、噴霧、接觸、印刷、浸漬、填補、施配、計量及其組
合。此後可施加熱量及/或壓力。
在一個非限制性實施例中,彈性聚合物組合物經分散體印刷至織物上或至剝離型紙上。分散體可藉由各種印刷方法印刷,包括:覆層網版印刷及凹版印刷。印刷設計可經改造以賦予產品所需屬性,諸如:定向強度、支撐、單向拉伸、雙向拉伸、拉伸及回復、流體轉移效率或增加的吸收度。
基礎織物自身可為用於拋棄式個人用品(諸如但不限於尿布、女性衛生產品及失禁襯墊)之製造中的任何吸收性織物。包括聚胺基甲酸酯脲組合物賦予吸收性織物拉伸回復之益處。其可用於多種不同拋棄式個人用品,諸如但不限於尿布、女性衛生產品及失禁襯墊、擦拭物、哺乳襯墊、乳房襯墊、除塵襯墊、床墊、傷口襯墊,
具有拉伸回復性之拋棄式個人護理用品係藉由在目標區域施用粉狀顆粒形式之彈性聚合物組合物而提供。彈性聚合物組合物可在製備拋棄式個人護理用品之前施用至吸收性織物,施用至拋棄式個人護理用品,或施用至織物及拋棄式個人護理用品兩者。彈性聚合物組合物含量為基礎織物重量之約1%及至約30%。
可視情況包括於彈性聚合物組合物中之其他添加劑包括(但不限於)抗氧化劑、UV穩定劑、著色劑、顏料、交聯劑、相變材料(亦即,Outlast®,可購自Outlast Technologies,Boulder,Colorado)、抗菌劑、礦物質(亦即銅)、微膠囊化幸福添加劑(亦即真蘆薈、維生素E凝膠、真蘆薈、海帶、菸鹼、咖啡鹼、香味或芳香)、奈米顆粒(亦即二氧化矽或碳)、碳酸鈣、阻燃劑、抗黏添加劑、氯降解抗性添加劑、維生素、藥品、芳香劑、導電添加劑及/或染料輔助劑(亦即Methacrol®,可購自E.I.
DuPont de Nemours,Wilmington,Delaware)。可添加至彈性聚合物組合物之其他添加劑包含黏著促進劑、抗靜電劑、防縮孔劑、防蠕變劑、光學增亮劑、聚結劑、導電添加劑、發光添加劑、流平劑、凍融穩定劑、潤滑劑、有機及無機填充劑、防腐劑、調質劑、熱變色添加劑、驅蟲劑、及潤濕劑。此類視情況存在之添加劑可在方法允許的情況下在聚合物組合物分散之前、期間或之後添加至彈性聚合物組合物。
至少一種凝聚劑可視情況用於控制分散體穿透至織物或其他物品中。可用凝聚劑之實例包括硝酸鈣(包括硝酸鈣四水合物)、氯化鈣、硫酸鋁(水合)、乙酸鎂、氯化鋅(水合)及硝酸鋅。
塗層、分散體或織物可著色或染色且亦可在該方面用作設計元素。
可使用屬於本發明範疇內之彈性聚合物組合物製造的拋棄式個人用品之實例包括(但不限於):尿布、女性衛生產品、失禁襯墊等。
在以下實例中,使用以下分析方法。
在指定負載(亦即,力)下沿織物拉伸方向評估織物之%伸長率,織物拉伸方向為複合紗(亦即,緯紗、經紗或緯紗與經紗)之方向。自織物切割三個尺寸為20cm×6.5cm之樣品。長尺寸(25cm)對應於拉伸方向。部分地拆散樣品以將樣品寬度降低為5.0cm。樣品接著經調節以在20℃ +/- 2℃及65%相對濕度+/- 2%下維持至少16小時。
在自樣品末端6.5cm處製得橫越各樣品寬度之第一基準。在自第一基準20.0cm處製得橫越樣品寬度之第二基準。自第二基準至樣品之另一端之過量織物用於形成及縫合線圈,可向線圈中插入金屬大頭針。接著將
凹口切割成線圈以使得可將重量附加至金屬大頭針。
夾緊樣品非線圈端且垂直地懸掛織物樣品。經由懸掛織物線圈將17.8牛頓(N)重量(4 LB)附加至金屬大頭針,以便藉由重量拉伸織物樣品。藉由允許樣品由重量拉伸三秒且接著藉由提昇重量手動地緩解力來「訓練」樣品。此循環進行三次。接著允許重量自由懸掛,由此拉伸織物樣品。在織物處於負載下時量測兩個基準之間的以毫米計之距離,且此距離標示為ML。基準之間的原始距離(亦即,未拉伸距離)標示為GL。如下計算各個別樣品之%織物伸長率:%伸長率(E%)=((ML-GL)/GL)×100
將三個伸長率結果平均以作為最終結果。以下部分提供本發明之組合物的進一步說明。此等實施例僅為說明性的且不欲以任何方式限制本發明之範疇。
非織物為可商購材料,其包括「紡黏型織物」紡製花邊非編織物、氣流成網形成的非織物網及材料、濕法成網非織物及含有熔紡纖維之織物及材料,且大部分由聚酯(諸如PET或PBT)、聚烯烴(包括PP及PE)、PP/PE雙組分纖維、或PET/PP雙組分纖維構成,基本重量範圍介於20gsm至200gsm。基本重量(Z)藉由非織物之重量(Xg)除以單位面積(Ysm(平方公尺)測定。Z=X/Y[Zgsm]
拉伸非編織材料藉由用聚胺基甲酸酯分散體(PUD)塗佈非織物、藉由氣動力或在環境下乾燥且在高溫(100℃至200℃)及滯留時間(5秒至45秒)下固化獲得,從而賦予非織物彈性性質。若干種技術可用於溶液塗佈,然而,就本發明而言,網版印刷、接觸塗佈、輪轉式凹版塗佈、平版印刷為當中較佳的模式。採用網版圖案允許選擇性印刷,由此賦予經塗佈非織物表面圖案。舉例而言,你可選擇存在開放區域及封閉區域之網版設計。PUD塗層將經由網版之開放區域遷移以塗佈非織物,從而產生選擇性塗佈或圖案塗佈。
1.將較佳可橫向延伸之可延伸非織物模切至以下尺寸:8吋寬及11吋長。
2.測定以公克為單位之非織物樣本的重量[A]
3.測定以平方公尺為單位之面積[B]
4.將網版(所有開放網版或選擇性網版)置放在乾燥非織物上
5.將PUD傾倒在網版上且經由網版開口使用網版印刷刀片將PUD印刷至非織物上。
6.藉由氣動力或環境乾燥濕潤的經塗佈非織物
7.藉由加熱及滯留時間固化乾燥的非織物
8.測定以公克為單位之固化非織物樣本的重量[C]
在塗佈之前非織物的基本重量=A/B
(拉伸非織物)經塗佈非織物或固化非織物之基本重量=C/B
使用傳統INSTRON拉伸方法,拉伸非織物之伸長率測定為在5%至200%之範圍內。其中允許拉伸回復100%至50%。因此設定0%至50%之範圍。0%設定意指100%回復;50%設定意指50%回復。
此拉伸編織樣品經24小時之濕蒸氣滲透率(MVTR)範圍為100g/m2至4000g/m2。
經聚胺基甲酸酯溶液塗佈之膜(PUD)按以下製備[請提供用於製造膜之步驟。膜厚度可在0.5密耳至5密耳之範圍內。
拉伸膜之伸長率測定為400%至2000%。此拉伸膜樣品經24小時之濕蒸氣滲透率(MVTR)範圍為50g/m2至2600g/m2。
用於MVTR濕蒸氣滲透率之測定的分析方法如ASTM E96。
