Surface Graft Polymerization of Acrylamide onto Plasma Activated Nylon Microfiber Artificial Leather for Improving Dyeing Properties

Abstract

Abstract-To improve surface wettability and dye-ability of Nylon microfiber artificial leather, we apply oxygen plasma treatment and subsequently graft-polymerize acrylamide (AAm) on the surface. The surface properties of AAm-grafted Nylon microfiber artificial leather are characterized by FT-IR, SEM, ESCA and dyeing density (C.I.reactive Blue 4). The dyeing rate of AAm-grafted Nylon microfiber artificial leather, up-regulated with higher acrylamide grafting concentration, increases to 67.1 mg/cm 2 , and remains 66.4 mg/cm 2 after rinsed by water, showed better stability than that of control and oxygen plasma modified Nylon microfiber artificial leather. The water-absorptivity of s-graft acrylamide is five times than that of control. From the results, the efficiency and density of dyeing are both improved, indicating that plasma graft polymerization process could contribute to promote the absorption of dye on the artificial leather.

Surface Modification of Bamboo Charcoal by O2 Plasma Treatment and UV-Grafted Thermo-Sensitive AgNPs Hydrogel to Improve Antibacterial Properties in Biomedical Application

“…As Figure 4 shows of (a) un-modified, (b) O 2 plasma treatment (100 W), and (c) O 2 plasma treatment (100 W) +UV graft thermo-sensitive AgNPs hydrogels BC specimens. It could be observed that several adsorption peaks after O 2 plasma treatment appeared, such as, for example, -OH at 3050~3250 cm −1 , C=O at 1700–1720 cm −1 , and C-O at 1140 cm −1 , were reduced [ 37 , 38 , 39 , 40 , 41 ]. The increase in these oxygen-containing functional groups revealed the due to oxygen atom bonding to hydrogen atoms on the surface during O 2 plasma treatment [ 37 , 38 ].…”

“…A plasma surface treatment system is a unique modification technology that is an advantageous and versatile technique in which plasma activation treatment and surface graft polymerization achieve uniformity and function [ 35 , 36 , 37 , 38 ]. Plasma treatment is used to alter the surface properties to increase the adhesion, wettability, and other surface characteristics of various materials [ 37 , 39 , 40 , 41 ].…”

Alkaline Hydrolysis and Dyeing Characteristics of Sea-Island-Type Ultramicrofibers of PET Tricot Fabrics with Black Disperse Dye

“…The increasing demand for high-quality textile materials, especially in the automobile and leisure industries, has driven the development of high-value-added synthetic fibers in which the advantages of synthetic and natural fibers are supplemented [1][2][3][4]. For example, the consumption of modified polyethylene terephthalate (PET) fibers, which are economical and exhibit excellent mechanical properties and chemical stability, has grown substantially in recent years [4][5][6][7][8][9]. To address the problem of uniformly textured PET fibers, the development of properties such as soft texture, flexibility, glossy drape, and absorptivity similar to those of nylon and rayon has been an engaging subject of study [10].…”

Acetic-Acid Plasma-Polymerization on Polymeric Substrates for Biomedical Application

“…In order to enhance other applications of the materials, and without there being any deterioration in the bulk properties, surface modification plays a very important role in various fields [8,9,10,11,12,13]. There are several methods that have been considered and developed for altering the interactions of materials with their environments, such as adsorption, oxidation by strong acids, ozone treatment, plasma (glow discharge), corona discharge, photo activation (UV), ion, electron beam, and so on [14,15,16,17]. Among these methods, plasma surface modification processes account for most of the commercial uses of plasma technology because they are fast, efficient methods for increasing the adhesion, wettability properties and other surface characteristics of a variety of materials [7,18,19,20].…”
