Inkjet printing on polyester fabric displays versatile environmental advantages. One of the significant benefits of inkjet printing is a dramatic enhancement of the printing quality. In this study, xanthan gum—a bio-based thickening agent accompanied by several salts—was adopted for the pretreatment of polyester fabric aiming at improving the sharpness and color depth of inkjet printed patterns. The influences of four metal salts (NaCl, KCl, CaCl2 and MgCl2) on inkjet printing performance were studied. More importantly, a quantitative method for evaluating the sharpness of an inkjet printed pattern was established according to the characteristics of anisotropy and isotropy of diffusion and adsorption of ink droplets on a fiber surface. Results showed that xanthan gum along with a low dosage of bivalent salts can significantly improve the color depth (K/S value) and sharpness of the printed polyester fabrics. It is feasible to evaluate the sharpness of inkjet printed polyester fabrics using a five-stage system, selecting the inkjet ellipse coefficient (T) and inkjet ellipse area (S), which can provide a quantitative and rapid evaluation method for defining inkjet printing.

Although Polyester has outstanding wearability, it only has few reacting functional groups in its surface, so protein can not be grafted firmly on polyester fiber surface. Therefore few reports are about grafting protein on polyester fiber’s surface. In this study, the surface of polyester was encased with hydroxide. Then the polyester fibers could be grafted with milk protein by using a synthetic crosslinkages compound. The structure of grafting milk protein polyester fabric was studied by SEM, and the wearability was measured too. Experimental results showed that milk protein could be grafted firmly on polyester through encasing and crosslinking technology. Milk protein could not be washed in the washing process. With the increase of grafted milk protein rate, the whiteness of polyester almost did not change; the cockle elasticity increased firstly, and then decreased, flexural stiffness and hygroscopicity property increased monotonously, moisture permeability increased firstly and decreased subsequently, and antistatic property increased greatly. Encasing hydroxide and grafting milk protein technology is an effective method to produce high functional polyester fabrics.

t is pre-mordant dyeing. Dyeing property of Carmine, gardenia yellow and sodium copper chlorophyll on cotton fabrics which were pre-treated by metal mordant (FeSO4AlCl3 and ZnCl2 ) was studied. The reasonable pre-treatment was determined by comparing the color depth (K/S value) of dyed samples. And then, the dyed samples were treated with no-iron finishing resin 931-33 to fix the color. The result shows that the color depth of cotton fabric is greatly improved after determined pre-treatment, and the washing fastness is improved after color fixing.

In this article, an experimental work is presented to evaluate the sensorial properties of polyester fabric constructed by nano-filament yarn. For this purpose Nano Filament polyester fabric was fabricated and compared with the spun polyester/cotton (PC) and polyester/viscose (PV) blended fabric by using Kawabata evaluation system (KES-system) to assess the handle of the fabric based on mechanical characteristic. The results revealed that the fabric made from PC and PV blended fabric were stiffer than nano-filament polyester fabric. The higher hand value (THV) resulted in lower stiffness (Koshi), and higher smoothness (Numeri) and fullness (Fukurami).Hand values of PV blended fabric were close to nano-filament polyester fabric rather than PC fabric. The overall results of tensile, shearing, bending, compression and surface characteristics of nano-filament polyester fabric were found best as compared to PC and PV blended fabric.

Dyeing Method

Polyester fabrics were dyed with prepared disperse dyes using the high temperature dyeing method. The dye exhaustion of the dye baths were compared to the low-temperature dyeing method in an attempt to study the proportion of the dye effluent solution that affects the environment. The dye uptake of the high temperature dyeing method (HT) of polyester fabric was compared with low temperature dyeing, hence (HT) increased the color strength of the investigated dyes by 309 and 265%. This means that the amount of dye present in the dye effluents by using the high-temperature dyeing method is almost non-existent, and this is reflected positively on the environment as these wastes pollute the environment. Post-treated polyester fabric was prepared through a two-step hot process after being immersed in a solution of Titanium (IV) oxide nanoparticle sizeTiO2 NPs (21 nm primary particle size) at 80 °C followed by curing at 140 °C. The treated fabric realized an optimum UV protection factor of 34.9 and 283.6 degrees. These fabrics also demonstrated a strong ability to improve the light fastness properties. Finally, the potential applications of such value-added fabrics as self-cleaning and antifungal activities were investigated. The results indicated that the treated dyed fabrics with TiO2 NPs endowed fabrics with the excellent self-cleaning of methylene blue dye. From the above, the treated fabrics with nano-titanium dioxide can be used in some promising fields, for example, medical ones.

System Performance Evaluation

Currently, e-learning systems are being widely used in all stages of education. However, it is difficult for school administrators to accurately assess the actual usage performance of a new system, especially when an organization wishes to update the system for users from different backgrounds using new devices such as smartphones. To allow school administrators to conduct upgrades of e-learning systems that take into consideration students' current usage conditions, this study proposed a two-stage system evaluation approach to explore the adoption of new systems. We collected 352 samples in Stage I. The goal of this Stage I was to propose a research model to understand the usage intentions of college students toward campus e-learning systems and also the factors which showed significant differences between PC and smartphone usage. A total of 30 trained students participated in Stage II. The goal of Stage II was to propose a system performance evaluation method to evaluate the performance of the new and existing systems according to the concerned factors of smartphone users after actual system use. Finally, based on our research model and system performance evaluation method, we put forward conclusions and suggestions that schools could use as references for future system procurements and updates.

Sulfonamide Dyes

The current study targets to synthesize some new sulfonamido-hydroxythiophene dyes for dyeing polyester fabrics with estimated antibacterial activity. The structure of sulfonamide dyes was adapted by conducting with sulfadimidine and sulfamethaxole through the coupling reaction. The synthesized derivatives were established by spectroscopic tools (Fourier transform infrared spectroscopy, proton nuclear magnetic resonance). Hydroxy-thiophene-containing sulfonamides were utilized for dyeing polyester fabric. The prepared sulfonamido-hydroxythiophene dyes were applied on polyester fabrics after establishing the optimum dye conditions, and afterward their dyeing properties, light, washing, perspiration, rubbing and sublimation fastness were determined. Meanwhile, the improved dyes demonstrated respectable fastness results and antibacterial properties against some gram-positive and gram-negative bacteria.
