Influence of nickel ions for electroless Ni–P plating on polyester fabric

Properties of electroless Ni–P plated polyester fabric mainly depend on the plating bath constituents/conditions. The effects of NiSO4 concentration of the plating bath on the deposition rate, phosphorus content, surface morphology, and crystal structure of the electroless Ni–P plated polyester fabric were investigated. The study revealed that phosphorus content in the deposits decreased at higher NiSO4 concentration. SEM micrographs showed that nodule size of the Ni–P deposits increased. All the Ni–P deposits had an amorphous structure. The electromagnetic interference (EMI) shielding effectiveness (SE) of electroless Ni–P plated polyester fabric was evaluated. With the rise of nickel ion in the solution, the EMI SE of the Ni–P plated polyester fabric increased.

Innovative Layered-combination Mode for Digital Jacquard Fabric Design:

Digital jacquard fabric has its design concept and method directly borrowed from computer images and color modes. This has enabled the creation of innovative jacquard fabric design that is far beyond what freehand patterns can express. In this paper, the principles of digital jacquard designing have been classified into two parts: colorless mode and colorful mode, and an innovative layered-combination design mode has been suggested that contains this new design concept, by which digital jacquard fabric can be designed from colorless single-layer structures to colorful compound structures. As a result, designed jacquard fabrics are capable of expressing picturesque and photo-realistic effects with a mega-level color number on the face of the fabric. It is envisaged that the results of the study are of tremendous benefit to the creation of new jacquard fabrics with inimitable digital effects that can be manufactured.

Optimization of electroless nickel plating on polyester fabric

Electrical conductivity is an important property of electroless nickel plated fabric. The optimized electroless nickel plating method can provide useful information for textile industries to obtain optimum surface resistance and stable plating. In this study, a screening experiment with factorial design and response surface method (RSM) with central composite design (CCD) was used to optimize the electroless nickel plating on polyester fabric. A two-level full factorial design (FFD) was used to determine the effects of five factors, i.e. the concentrations of nickel sulfate, sodium hypophosphite and sodium citrate, pH and temperature of the plating solution on surface resistance of the electroless nickel plated fabric. It is found that the nickel sulfate concentration and temperature of the plating solution are the most significant variables affecting the surface resistance of electroless nickel plated fabric. The optimum operating condition is finally obtained by using a desirability function. The test for reliability for predicting response surface equations shows that these equations give an excellent fitting to the observed values. In addition, the deposit composition, surface morphology, crystal structure and electromagnetic interference (EMI) shielding effectiveness (SE) were studied. The EMI SE of the nickel plated polyester fabric obtained under the optimal condition is about 60 dB at the frequency ranging from 2 to 18 GHz.

Shapeable Stretch Textiles via Simple Weaves for Seamless Woven Fashion

This paper proposes approaches to create shaped woven textiles (SWTs) for seamless woven fashion by designing diverse simple weaves and applying their dimensional changes. A widespread stretch material (spandex) was selected as the main fillings for shape changes. The research introduces the four design parameters of simple weaves for stretch fabrics. Twenty types of specimens in two different configurations of the stretch fillings were then produced. Correlations between the four parameters and dimensional changes of simple weaves were investigated. With respect to dimensional and textural changes, experimental results indicated corresponding divergences of specimens made by the different simple weaves and two types of configurations of fillings. By integrating these shape changeable weaves via jacquard designs, several practical creations illustrated the sculptural capabilities of shaped textiles and aesthetical attributes. This research contributes to the integrated design and manufacture of future woven textiles and fashion.

Textile design application via electroless copper plating

Metallized textile has metallic color with reflective effect and smooth handle. The electroless copper plating on fabric using hypophosphite as a reducing agent is feasible process for design application. This study aims to investigate the appearance of the copper-plated Green-PN fabric produced by electroless plating with different deposition conditions including different nickel sulfate concentrations and pH of plating bath. Various colors were produced after the copper-plated fabrics had been exposed to the copper plating bath at 85°C and pH 8.5 for different time. Design application of the electroless copper plating on Green-PN fabric and Black-CVPN fabric was carried out. The electroless copper plating could change the original appearance of the fabric through the deposition of copper particles on the fabric surface. The final pattern was well-defined using many details such as lines and forms created by the design methods. The study laid the foundation of the electroless copper plating for textile design.

Influence of Deposition Parameters and Kinetics of Electroless Ni-P Plating on Polyester Fiber

The electroless nickel-phosphorous (Ni-P) plating on polyester fiber using sodium hypophosphite as a reducing agent in alkaline medium was studied. The effects of plating parameters including concentrations, pH and bath temperature of the plating bath on deposition rate of the electroless Ni-P plating were investigated. The results reveal that the deposition rates increase with the increase in the concentration of nickel sulfate, sodium hypophosphite, pH and bath temperature, respectively. However, it is determined that the deposition rates decrease with the rise of sodium citrate. The kinetics of the deposition reaction was investigated and an empirical rate equation for electroless Ni-P plating on polyester fiber was developed.

Effects of deposition parameters of electroless copper plating on polyester fabric

Properties of electroless copper-plated polyester fabric mainly depend on the plating bath constituents/conditions. The nickel serves to catalyze the copper deposition when hypophosphite is used as a reducing agent. In this study, the effects of deposition parameters including additive NiSO4 concentration and pH on microstructure and properties of the electroless copper plating on polyester fabric using hypophosphite as a reducing agent were investigated. The results show that at a higher NiSO4 concentration, the copper content present in the coating decreases whereas the nickel content increases slightly. On the other hand, the copper content present in the coating increases, whereas the nickel content and phosphorus decreases with respect to the rise of pH. The morphology of the copper deposits show that the particle size increase with respect to the rise of NiSO4 concentration and pH. The XRD patterns indicate that the copper-plated polyester fabrics are crystalline. In addition, there is a decrease in the surface resistance and an increase in the electromagnetic interference (EMI) shielding effectiveness (SE) with respect to the rise of Ni2+ concentration and pH of the solution as a result of gaining a greater weight in the deposits. The results suggest that the copper-plated polyester fabrics have a great potential application as an EMI shielding material.

Full-colour compound structure for digital jacquard fabric design

Inspired by the design method of digital image, based on gamut weaves design and the established weave database, a study has been carried out to reform the traditional design approach of jacquard textiles via the deployment of digital-layered combination design mode towards the creation of digital jacquard. To this end, the structural design method has been reinvented under layered design mode. This article presents an innovative design method called ‘full-colour’ compound structure design by which digital jacquard fabric is made possible by non-backed structure. This ‘full-colour’ technique offers a novel-colour shading effect on the surface of a digital jacquard fabric where the colour threads juxtapose in an even orderly fashion, e.g. 1:1, 1:1:1:1, etc. Moreover, this innovative design approach befits well the computer-programmed design that meets the technical requirement of balanced interlacement, and thus fabrics produced by this method pose no problem in mass production.

Metallized textile design through electroless plating and tie-dyeing technique

The aim of the study is to investigate design effects of the electroless metal plated fabrics in order to meet the requirement of high technical and apparel applications by using tie-dyeing technique. The appearance of nickel plated and nickel/copper multilayer plated fabrics obtained under different conditions and tie-dyeing technique was investigated, respectively. Metallized textile design by nickel and copper was developed using tie-dyeing method. The nickel/copper multilayer plated fabric indicates that the color changfe from red to gray is with respect to an increase of thickness of the nickel deposits. The resisting effects by using tie-dyeing on the metallized fabrics depend entirely on the texture and strength of the tie-dyeing conditions used. The study reveals that metallized textiles design by combining electroless plating and tie-dyeing are promising for decorative and fashion application.
