Description
技术领域
本发明涉及纺织面料生产技术领域,具体涉及一种阻燃拉绒面料的加工方法。
背景技术
随着人们生活水平的提高,人们对纺织面料的要求也越来越高,大多希望纺织面料具有美观等性能,又具有如防水、阻燃等的特殊性能。而窗帘面料是纺织面料中的其中一种产品,是一种比较常见的家用纺织品,在窗帘面料中,使用最多的是涤纶纤维或芳纶面料等等的纤维面料。随着高科技的迅猛发展,新材料、新技术和新工艺被大量应用到面料上,因而出现了形形色色的功能性面料。对于面料,往往要求绿色环保、具有较好的阻燃性和耐久性。为使窗帘面料具备这些特点,通常要对窗帘面料进行阻燃整理,为具有更好的遮光和美观效果,还需进行拉绒处理。
现有技术中,此种面料加工时只是进行简单的拉绒和阻燃处理,专利申请号为201610671070 .9的一种阻燃纤维面料的加工方法,其公开了面料的阻燃加工方法,但是其只进行一次脱胶处理,脱胶处理不完全,会影响后续阻燃处理,阻燃处理只是将面料置于阻燃液中进行一次处理,阻燃效果不理想,且现有技术中拉绒时容易掉绒,不能保持厚度,需要进一步优化,使得脱胶更彻底,改善拉绒和阻燃效果。
发明内容
本发明要解决的技术问题是提供一种阻燃拉绒面料的加工方法,能够使拉绒前的脱胶处理更彻底,拉绒效果更好,不易掉绒,可保持绒的厚度,且通过两次阻燃处理,阻燃效果更好。
为解决上述技术问题,本发明的技术方案为:包括以下步骤:
S1、将纤维面料在定型机中以温度为190-200℃下高温焙烘30-50s,车速为20m/min~25m/min,进行预定型处理;
S2、经过预定型处理后,将纤维面料放入硅酸钠水溶液中进行脱胶处理15min~20min,得到一次脱胶后的纤维面料;
S3、对纤维面料进行二次脱胶处理,将纤维面料放入阻燃液和碳酸钠的混合溶液中进行脱胶,同时进行首次阻燃处理,二次脱胶和首次阻燃处理同时进行,处理后的混合溶液取其上清液待用;
S4、以温度120-130℃进行烘干,车速为20-25m/min,确保布面干燥;
S5、将脱胶后的纤维面料进行拉绒前处理,轧起毛油,为起绒做准备,之后进行拉绒处理,拉绒后定型,定型温度控制在140-160℃之间,车速20-25m/min,轧膨松剂,正面布向上定型,定型工艺风量设从大到小定型,控制绒面丰满度;
S6、将拉绒后的纤维面料浸入S3中待用的阻燃液中,进行二次阻燃处理,阻燃液渗透到纤维面料内,再进行烘干处理,烘干温度为70-85℃,得到具有阻燃的拉绒纤维面料。
进一步地,所述步骤S2和S3中,脱胶处理的温度控制为90℃~100℃,体系的压力为12MPa~15MPa。
进一步地,所述步骤S5中,首先对纤维面料正面进行三次拉绒处理,然后对纤维面料反面进行一次拉绒处理,滚筒转速750-950r/min,布速为6-9m/min,再对正反面进行梳毛、剪毛处理,梳毛辊转速在 350-650r/min,布速4-7m/min,剪毛刀速度在850-1300r/min,布速在6-12m/min,绒面丰满,厚度在3-3.5mm,然后放入摇粒筒中进行滚球处理,先放蒸汽5-12分钟,烘干5-8分钟,再进行冷风冷却处理5-10分钟。
进一步地,所述步骤S3和S6中,阻燃液主要由以下成分按质量份组成:
磷酸酯阻燃剂2%~3%、环氧丙烯酸酯0.2%~0.3%、分散剂0.2%~0.3%、磺基琥珀酸双(2-甲基戊基)酯钠盐0.4%~0.6%、硼酸锌0.2%~0.3%、防沉剂0.1%~0.2%,余量为水。
进一步地,所述防沉剂为有机改性膨润土、气相二氧化硅、聚乙烯蜡、聚酰胺蜡或钛酸酯偶联剂防沉剂中的至少一种。
本发明的优点在于:在拉绒处理前进行两次脱胶处理,使得脱胶处理更彻底,确保后续的拉绒和阻燃整理的效果,拉绒时不易掉绒,能保持厚度,在面料拉绒的前后分别进行一次阻燃处理,两次阻燃处理,阻燃的效果更好;
二次脱胶处理和首次的阻燃处理合并为同一步骤,二次脱胶处理的同时可起到首次阻燃处理的效果,简化处理步骤,提高生产效率;
二次脱胶处理和首次的阻燃处理后,由于碳酸钠具有絮凝效果,可使脱去的胶自动进行沉淀,使用过的阻燃液自动进行分离,无需另外再进行处理,上层清液为阻燃液,可重复利用于后续的二次阻燃处理,重复利用,减少阻燃液浪费。
