聚酯纺粘非织造干花基材工艺与热轧技术研究
|
摘要
我国自20世纪80年代起,开始引进纺粘设备和技术,生产纺粘法非织造布。由于纺粘非织造布有产品性能好、成本低、用途广等优点,近年来纺粘法非织造布得到了较为迅速的发展,每年的产能与产量都有一定增加,可见纺粘发非织造产品越来越受到人们的欢迎。
随着人们生活水平的提高,人们对装饰、美化、保健等多方面的要求有所提高,让生活舒适美好。目前市面上所采用的装饰用干花大都为机织产品,聚酯纺粘装饰非织造材料的开发,既符合非织造材料向低成本、高附加值方向发展的趋势,又迎合了人们对新型装饰材料的追求。
本研究首先通过对聚酯纺粘非织造布和传统干花基布进行测试,分析得出聚酯纺粘非织造布的折皱回复性,抗弯刚度,比传统干花基布好。除此之外,聚酯纺粘非织造布由于其纤维的杂乱排列,与植物经脉相类似,较为逼真。但是传统干花基布在细度,强力,弯曲弹性模量方面比聚酯纺粘非织造布的性能优越。
针对聚酯纺粘非织造上述不足的性能,本研究通过改变纺粘生产中牵伸工艺的气流压力来改变聚酯长丝的细度,从热轧粘合中点粘合角度分析了轧点形状,轧点面积,轧点百分比以及轧点的排列方式对聚酯纺粘非织造布性能的影响。除此之外对聚酯纺粘非织造布进行硬挺整理从而提高聚酯纺粘布的弯曲弹性模量。
研究表明,在聚酯纺粘非织造布牵伸工艺中,增加气流压力可以使得聚酯长丝的细度降低,并且分析得出在牵伸压力至少为3bar时,才能获得结晶,取向,均匀性较好的聚酯长丝。此外,在提高轧点面积,轧点面积比例的同时,采用方形轧点与纤维排列方向成45°排列的轧点排列,可以使得聚酯纺粘非织造布的强力,硬挺度性能更好。对于硬挺整理方面,本研究确定了采用TF-630硬整理工艺：TF-630硬挺剂与TF-630C催化剂的比例为5：1,TF-107 T渗透剂1 g/L。轧辊压力0.3MPa,轧液率150%。选取硬挺整理剂TF-630的浓度选取为200g/L,焙烘温度180℃,时间120S时能够获得较好的硬挺整理效果。经过整理后,聚酯纺粘非织造布的强力,抗弯刚度都得到了增加,弯曲弹性模量与传统干花基布相当,虽然折皱回复性有所下降,但是仍然符合干花用布的要求。
Since the nineteen eighties, china began with the introduction of spunbonded equipment and technology, and product spunbonded nonwovens. As a result of spunbonded nonwovens had good product performance, low cost, wide application and other advantages, in recent years the spunbonded nonwovens had been relatively rapid development, the annual proeduction capacity and yield increased quickly,it showed that spunbond nonwoven products were more and more popular.
With the improvement of people's living standard, the requirements on the decoration, beautification, health and other aspects increased quickly. Because they could make life beautiful and comfortable.Currently the decorating with flowers on the market were used in mostly woven material. The mean in the development of polyester spunbonded nonwoven products in decorative materials was not only the lower cost nonwoven material,but also high added value and development trend,last but not least,it could meet the people's pursuit of new decorative material.
This study firstly test polyester spunbonded nonwovens and the traditional simulation base cloth,and then analysised the crease recovery, bending stiffness of polyester spunbond nonwoven fabric were better than the base cloth's,In addition, due to the fiber random arrangement of polyester spunbonded nonwovens, the simulation was more realistic. But,the base cloth was superior performance in fineness, strength, bending elastic modulus ratio than polyester spunbonded nonwovens.
Aiming at the deficiency of polyester spunbond nonwovens performance, this study changed air pressure in Spunbonded Production drafting process to change the polyester filament fineness. In addition, it analysised the influence of the shape of the rolling spot, spot size, proportion of the point size and the orientation of the polling spot on the property of nonwoven from the spot bonding point of view. At last through stiffen finishing of the polyester spunbonded nonwovens to improve the bending modulus of elasticity of polyester spunbonded nonwovens.
The research showed that increased the air pressure could make the polyester filament fineness decreased in the drafting process of the polyester spunbonded nonwovens, and when the draft pressure was at least 3bar, it could obtain the crystallization, orientation, the uniformity of polyester filament. In addition, with improving rolling point area, rolling point area ratio,if point was the square and direction of fiber alignment of 45 degrees was arranged rolling point arrangement, could make polyester spunbonded nonwovens strength, stiffness, better performance. In addition, this study identified using TF-630 hard finishing process:TF-630 stiffening agent:TF-630C catalyst is 5:1, TF-107T lg/L penetrating agent.Roller pressure 0.3MPa, liquid-mangling rates 150%. The selection of stiffening agent TF-630 concentration was for 200g/L, baking temperature of 180℃, finishing time was 120S, it could obtain better stiffening effect. After the consolidation, polyester spunbonded nonwovens strength, flexural rigidity had been increased, bending elastic modulus were the same of woven cloth, although crease-recovery droped a little, but it was still consistent with the requirements of decorative cloth.
