低温等离子体处理对涤纶起绒织物数码喷墨印花的作用
|
摘要
针对涤纶起绒织物表面绒毛浓密、数码喷印墨水难以渗透、容易造成露白现象的问题,利用低温等离子体处理涤纶起绒织物,并对其改善数码喷印效果进行研究。通过采用有机硅和氧气低温等离子体对涤纶起绒织物进行处理,结果发现:当疏水性有机硅等离子体处理时,墨水在织物表面向绒毛根部的渗透性下降,数码喷印后的表观得色深度K/S值相较于未处理织物有所增加;进一步用氧等离子体处理后,墨水织物绒毛里的渗透性提高,并且渗透性随着氧等离子体处理的时间及功率增加而增强,数码喷印花墨水的渗透性相较于未处理织物有明显的提升,但其K/S值与未处理织物相比并未有明显变化。通过对等离子体处理涤纶起绒织物纤维的扫描电镜分析,发现纤维表面出现被刻蚀、表面粗糙度增加的现象,该现象的出现提升了数码喷印后织物的表观得色深度,从而达到了研究目的。
The surface of polyester pile fabric is densely covered,the digital printing ink is difficult to penetrate and whitening phenomenon easily caused.Aiming at the above problems,the low-temperature plasma was used to treat the polyester pile fabric,and the effect on digital printing improvement was studied.The polyester fabric was subjected to hydrophobic and hydrophilic treatment by low temperature plasma.It was found that when the surface of the fabric was hydrophobic,the apparent color depth K/S value after digital printing increased obviously,compared with the untreated fabric,but the ink permeability was poor.When the surface of the fabric was hydrophilic,the permeability of the digital jet printing ink significantly improved,compared to the untreated fabric,and the permeability was dependent on the time and power of the plasma treatment.But,its K/Svalue did not change significantly compared to untreated fabric.Scanning electron microscopy analysis of polyester pile fabric treated by low-temperature plasma revealed that the surface of the fiber was etched and the surface roughness increased,which improves the apparent color depth of the digitally printed fabric to a certain extent,achieving the research purpose.
