Description

一种乳胶纤维棉及其制备工艺
技术领域
本发明涉及纤维棉技术领域，具体涉及一种乳胶纤维棉及其制备工艺。
背景技术
现有生产乳胶床垫或者其它乳胶制品时产生的边角乳胶和边角料等，一般都是过剩产品或者瑕疵品，而这些边角料瑕疵品一般都是直接废弃的，会造成资源的浪费，不环保。而现有的纤维棉一般通过纤维胶水粘合而成，不利于环保。
且现有的纤维棉弹性一般，压缩回弹差，而在生产乳胶纤维棉时，乳胶经过几道梳理容易变粉状损耗较大，梳理成网均匀度欠佳。
发明内容
为了克服现有技术中存在的缺点和不足，本发明的目的在于提供一种乳胶纤维棉，该乳胶纤维棉是由乳胶或乳胶边角料和纤维组成，可以将废弃的乳胶或乳胶边角料重新利用，环保；采用低熔点纤维直接粘合，不需要使用胶水，安全环保；且比现有的纤维棉性能优越，弹性好，压缩回弹高，舒适度强。
本发明的另一目的在于提供一种乳胶纤维棉的制备工艺，该制备工艺步骤简单，操作控制方便，质量稳定，生产效率高，生产成本低，可大规模工业化生产。
本发明的目的通过下述技术方案实现：一种乳胶纤维棉，所述乳胶纤维棉由包括如下重量百分比的原料：
本发明的乳胶纤维棉通过采用乳胶颗粒或粉末、聚酯纤维、功能纤维和低熔点纤维作为原料，并严格控制各原料的重量配比，制得的乳胶纤维棉比现有的纤维棉性能优越，弹性好，压缩回弹高，舒适度强。
优选的，所述乳胶纤维棉由包括如下重量百分比的原料：
更为优选的，所述乳胶纤维棉由包括如下重量百分比的原料：
优选的，所述乳胶颗粒或粉末由乳胶或乳胶边角料粉碎成颗粒或粉末状。本发明通过采用乳胶或乳胶边角料粉碎制成的乳胶颗粒或粉末，可以将废弃的乳胶或乳胶边角料重新利用，环保。
优选的，所述功能纤维包括竹炭纤维、大豆纤维、植物纤维、负离子纤维和远红外纤维中的至少一种。本发明通过采用上述功能纤维，可以使乳胶纤维棉具有特殊功能，如抗菌防臭、净化空气和人体保健等功能。本发明的功能纤维还可以为导电纤维、光导纤维、离子交换纤维、陶瓷粒子纤维、保温纤维、生物活性纤维、生物降解纤维、弹性纤维、阻燃纤维、香味纤维、变色纤维和防辐射纤维等，在不脱离本发明构思的前提下任何显而易见的替换均在本发明的保护范围之内。
优选的，所述低熔点纤维包括聚烯烃类低熔点纤维、聚酰胺类低熔点纤维和聚酯类低熔点纤维中的至少一种。本发明通过采用低熔点纤维，其具有优秀的热粘合性能，易与其他纤维混合，可以使乳胶纤维棉不需要使用胶水，通过低熔点纤维直接粘合，安全环保；还可以使乳胶纤维棉具有优异的耐洗性、稳定的可加工性和良好的弹力。
本发明的另一目的通过下述技术方案实现：一种乳胶纤维棉的制备工艺，包括如下步骤：将乳胶颗粒或粉末、聚酯纤维、功能纤维和低熔点纤维混合，搅拌均匀；梳理开松后再搅拌均匀，然后梳理成纤维网；经铺网加压后烘干，冷却成型，制得乳胶纤维棉。
优选的，所述乳胶颗粒或粉末由乳胶或乳胶边角料粉碎成颗粒或粉末状。本发明的制备方法通过将乳胶或乳胶边角料粉碎制成乳胶颗粒或粉末，可以将废弃的乳胶或乳胶边角料重新利用，环保。
具体的，先将乳胶或乳胶边角料粉经粉碎机粉碎成颗粒或粉末状，输送到混棉机，再按比例投放聚酯纤维、功能纤维和低熔点纤维，一起输送到混棉机搅拌均匀；将搅匀后的原料输送到开松机梳理开松均匀，再输送到给棉机搅拌均匀，然后输送到梳理机梳理成纤维网；将纤维网输送到铺网机均匀铺设成所需的宽度及厚度，加压后输送到烘箱，然后采用双网夹持输送到冷却机冷却，制得乳胶纤维棉。
本发明的乳胶纤维棉通过采用混料，梳理开松后再搅拌均匀，然后梳理成纤维网，经铺网加压后烘干等步骤，制得的乳胶纤维棉比现有的纤维棉性能优越，弹性好，压缩回弹高，舒适度强。
优选的，所述烘箱的温度为100-220℃。本发明通过将烘箱的温度控制在100-220℃，便于纤维棉的定型。
优选的，所述烘箱设置有风槽和风循环系统。热风循环烘箱可以使纤维棉受热均匀。
优选的，所述双网夹持输送采用铁佛龙输送网。采用铁佛龙输送网具有优良的不粘网及透风性能。
本发明的有益效果在于：本发明的乳胶纤维棉是由乳胶或乳胶边角料和纤维组成，可以将废弃的乳胶或乳胶边角料重新利用，环保；采用低熔点纤维直接粘合，不需要使用胶水，安全环保。
本发明的乳胶纤维棉环保，且比现有的纤维棉性能优越，弹性好，压缩回弹高，舒适度强。
本发明的制备工艺步骤简单，操作控制方便，质量稳定，生产效率高，生产成本低，可大规模工业化生产。
