Janus颗粒用于聚酯拒水整理

利用Janus颗粒改性聚酯织物表面,使其具有拒水性。Janus颗粒的亲水部分与聚酯活性表面结合,Janus颗粒的疏水部分赋予其拒水性。研究了改性聚酯表面的润湿性和表面形态,发现随着Janus颗粒浓度的提高,改性的织物表面显示出较大的水接触角和较小的倾斜角。由表面形态还注意到,Janus颗粒浓度较高时,会像山莓般聚集到改性长丝表面,对织物拒水性有影响。最后,试验证明了Janus颗粒质量分数为20%时对拒水纺织品的设计非常有效。

The effect of water repellency finishing on selected performance properties of upholstery fabrics produced from chenille yarns

Abstract

This study presents an evaluation of the effect of water-repellency finishing on the performance of upholstery fabrics manufactured from chenille yarns. Six different chenille yarns were manufactured as samples using piles made from three different raw materials (polyester, acrylic and viscose) and with two different heights. Then, six upholstery fabrics were woven used these chenille yarns in the weft direction and keeping all other weaving parameters fixed. Water repellency finishing was applied at 60% and 80% impregnation ratios using fluorocarbon-based finishing chemicals. The samples were tested for abrasion resistance and water repellency properties according to the standards. The results were evaluated statistically and graphically. The samples were analyzed before and after the abrasion process using a scanning electron microscope. As a result of the tests, water repellency of all the samples increased as expected after the finishing process. It was observed that the water repellency finish affected the abrasion resistance positively for all raw materials. Thus, the mass loss of the finished samples after the abrasion was less than that of the nonfinished samples. But, after the abrasion process, the water repellency of the samples was affected negatively.
