Chemical plating is one of the metallising treatment processes for fibrous materials that can produce unique textile properties.
It poses a great potential for textile products in application aspects including functional and decorative effects. This study
has investigated the operation condition and resultant performance of using chemical silver plating on polyester fabric. The
silver-plated polyester fabric exhibited a specific protective function and novel appearance if optimum chemical plating condition
was chosen. Furthermore, the fabric design practice employed by this chemical technique with design approach had achieved
the diverse effects. 相似文献

Electroless metal plated fabrics are favorable to be used as e-textiles due to the excellent conductivity and peculiar properties
of textiles such as flexibility. But, the electrical durability is not enough to be used as e-textiles. Therefore, we applied
polyurethane(PU)-sealing (single-sealing vs. double-sealing) onto the electroless metal plated polyester fabrics (Ripstop
vs. Mesh) to reinforce the electrical durability. We investigated the changes of electrical properties of the PU-sealed metal
plated fabrics after laundering by a multi-meter, examined the surface changes using scanning electron microscope, and checked
the metal existence using energy dispersive X-ray spectroscopy. And, we finally proved the possibility of the fabric strips
as transmission lines by alternating conventional earphone lines. PU double-sealing showed higher performance on Ripstop polyester
fabrics even after being laundered 10 times, which was almost the same as Cu-based typical conductive lines did. 相似文献

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. 相似文献

The effect of padding solution on the microwave heat dyeing of polyester fabric was studied extensively. Polyester fabrics
were impregnated in aqueous urea solution and aqueous sodium chloride solution for 10 min and then dyed for 7 min by microwave
apparatus (2 450 MHz, 700 W) under optimum conditions which provide good exhaustion. Aqueous solutions of urea and sodium
chloride showed more effective than water as a padding solution for microwave heat dyeing. The type of solvent added in padding
media and its concentration significantly affects the K/S values of dyed polyester fabric. Added solvents such as n-hexane,
acetone, and dimethyl formamide were also more effective than 100% water as padding media for the microwave heat dyeing. It
is supposed that the effect of used solvents on dyeing property of polyester fabrics depends on the solubility parameter difference
between solvent and polyester fabric. 相似文献

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. 相似文献

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. 相似文献

Small diameter vascular grafts were fabricated from pure Polyurethane (PU) as well as PU reinforced with a tubular weft-knitted
fabric. The tensile properties of the reinforced composite vascular grafts were compared with that of the tubular fabric itself
and the pure PU vascular grafts. The elasticity and strength of the reinforced vascular grafts were improved compared with
the tubular fabric. Strength of the reinforced vascular grafts was 5–10 times of the strength of the pure PU vascular grafts.
Expanding the tubular fabric to increase the inner diameter of the reinforced vascular graft reduced the graft’s strength
and initial modulus, but the difference was reduced as the PU content was increased. For grafts of the same inner diameter,
increasing the PU content increased the thickness and strength of the graft wall, which led to a general increase in the strength
and initial modulus of the composite vascular grafts. 相似文献

Poly(ethylene terephthalate) fabrics were metallized through electroless plating of copper. The copper plating was performed
on palladium-decorated polyaniline surfaces, and polyaniline was present as an intermediate layer on fabrics to facilitate
palladium formation. Different oxidation states of polyaniline were tested in their efficacy in Pd (II) reduction and subsequent
Cu plating. X-ray photoelectron spectroscopy was used to monitor the surface changes along the metallization procedure, and
surface resistance was measure to probe the electrical properties of the metallized fabrics. 相似文献

Five temporarily solubilized reactive disperse dyes were synthesized and characterized. They were applied to polyester/cotton
blend fabric using one-bath dyeing method without dispersing agent. The dye that has azonaphthalene chromophore seemed to
not only be exhausted on polyester but also react with cotton. But other dyes were selectively dyed on polyester and showed
limited uptake on cotton. Good levelling as well as moderate to good colour fastness was obtained with the dyes on P/C blend
fabric. 相似文献

In this paper, the capillary rise method was applied to evaluate the wicking property of polyester filament yarns. Effects
of twist, monofil cross sectional shape and texturing on the wicking height were discussed in details. The results indicated
that with the increase of twist level, the wicking height ascends until reaching the maximum height, and then descends. It
is also observed that under the same twist level, the wicking height of the five-leaf low-stretch yarn is the largest among
all those three kinds of yarns, and then is that of the conventional low-stretch yarn. The wicking height of the parallel-drawn
yarn is the smallest. 相似文献

In this paper, modifications of textile properties of polyester due to laser irradiation were studied. Properties included
fibre weight and diameter, tensile strength and elongation, yarn abrasion, bending, surface luster, wetting, air permeability
as well as crystallinity. Some properties were affected significantly while others were found unchanged. Besides, some properties
were positively affected and some were adversely changed. Generally speaking, laser irradiation could not affect the bulk
property of polymer due to its low penetration depth, and hence, the effect of the laser irradiation on the bulk and structural
properties was limited. However, the performance and comfort properties of the laser irradiated polyester could be largely
affected by laser irradiation as these properties could have been changed considerably if the surface was modified. 相似文献

Use of low temperature plasma treatment has been attempted in the textile industry and there the has been some success in
the dyeing and finishing processes. In this paper, an attempt was made to apply low temperature plasma treatment to improve
the antistatic property of polyester fabric. The polyester fabrics were treated under different conditions with low temperature
plasma. An orthogonal array testing strategy was employed for obtaining the optimum treatment condition. After low temperature
plasma treatment, the polyester fabrics were evaluated with different characterization methods. Under the observation of scanning
electron microscope, the surface structure of the polyester fabric treated by low temperature plasma was found to be seriously
altered which provided more capacity for polyester to capture moisture and hence increased the static charges dissipation.
The relationship between moisture content and half-life decay time for static charges was studied and the results showed that
the increase in moisture content would result in shortening of the time for static charges dissipation. Moreover, the antistatic
property of the low temperature plasma treated polyester fabric was greatly improved. In addition, the antistatic property
of the polyester fabric treated by low temperature plasma was compared with that of the polyester fabric treated with a commercial
antistatic finishing agent. 相似文献

In this study, mild acid based chelating agents (glycolic acid, gluconic acid, ethylenediaminetetraacetic acid, and citric acid) were used for the dyeing of polyester fabrics with metal sensitive disperse dye in closed dyeing process. The chelating and pH adjustment efficiencies were compared in disperse dyeing condition. In the comparative analysis with different chelating agents, glycolic acid showed a higher chelation efficiency and consequently showed higher dye bath exhaustion and color strength. Slight differences in the color fastness of the dyed samples obtained by employing four different chelating agents were observed. 相似文献

In this paper, a comparison between a mathematical and an experimental method for the evaluation of some process components
of polyester microfibre dyeing is presented. In the experimental part, a dyeing procedure was chosen, K/S values of the dyed
samples were measured and the coefficients of the mathematical formula presented in the mathematical part were obtained. K/S
values of different dyeing procedures were also measured. In the mathematical part, predicted K/S values were calculated by
a novel formula. The results of the two methods were then compared. According to the results obtained, the mathematical formula
presented in this study can be used for calculating the predicted K/S values at lower dye concentrations. 相似文献

The properties of a woven fabric made of poly(trimethylene terephthalate) (PTT) were investigated. The PTT fabric of draw
textured yarn (DTY) showed excellent stretch as good as a fabric containing spandex. However, the unique stretch of the PTT
fabric reduced dramatically by simple heat-treatment even at as low as 80 °C. To understand the phenomenon, the crimp rigidity
of the DTY was observed by SEM. It was found that the drastic reduction of stretch was caused by irreversible uncrimping of
PTT DTY after heat-treatment. Conclusively, it is of importance to optimize the texturing conditions for PTT DTY to make the
crimp more stable. 相似文献

Temporarily solubilized azo disperse dyes based on 1,2-substituted indoles were synthesized and characterized. Dispersant-free
dyeing of polyester by using the synthesized dyes has been investigated. The colour yields of the dyes on the polyester fabric
were found to be highly dependent on the dyeing pH, optimum results being obtained at pH 5. The dyes exhibited good to excellent
fastness properties on polyester while lightfastness was moderate. 相似文献

In present work, PET FDY has been used to blend with diacetate filaments by air texturing process and core-and-effect air-textured
yarns have been produced. The influences of both over-feeds of core and effect components on properties of textured yarns
were mainly examined. It was observed that a spun-like effect of diacetate filaments occurred during air texturing and there
were a little amount of free fiber ends besides loops on blended air textured yarns, while the number of free fiber ends changed
little with variation in over-feeds. The tenacity of textured yarns decreased with increase in over-feeds of effect or core
component. The breaking elongation increased with increase in over-feed of effect component, but decreased with increase in
over-feed of core component. The yarn stability improves when both over-feeds are increased. The effect of over-feeds on boiling
water shrinkage shows no clear trend. The core and average diameters are higher at high over-feed of effect component, but
the over-feed of core component exhibits little effect on yarn diameters. The number and size of loops are increase with increased
over-feed of effect component. 相似文献

This paper assesses the color difference and color strength values (K/S) obtained for eight disperse-dyed polyester fabric samples with different fabric construction parameters (weft yarn type,
weft yarn count, weft density and fabric weave) after four sets of abrasion cycles. Warp yarn type and count, warp density,
and warp yarn twist are the same for all fabrics. Fabric samples are dyed in a commercial red disperse dye (C.I. Disperse
Red 74:1) and four different abrasion cycles (2500, 5000, 7500, 10000) are used. TheK/S values of the abraided fabrics and color difference values between the control fabric (dyed but not abraided) and abraded
fabrics are calculated. The main differences in theK/S and color difference values are observed between 0–2500 abrasion cycles. The high tenacity of the polyester fibers and continuous
polyester yarns causes some fuzz but no pilling formation on the fabric surface that lead to increasedK/S values and color differences. Fiber dullness, yarn thickness, yarn density and fabric weave are concluded to have different
effects on the appearance after abrasion. 相似文献

The purpose of the research was to examine the effect of three different levels of enzyme treatment on the physical characteristics
and the end-use suitability of the lyocell fabrics made with four different types of commercial wood pulp. The appropriate
enzyme concentration for obtaining an optimum as well as consistent physical characteristics and fabric hand trait was 3 g/l for the concentration levels tested in the present investigation. Weight loss was more affected by higher enzyme concentration
than other physical properties. H2 was least affected by enzyme treatment for all three physical properties and fabric hand.
5 g/l concentration exhibited little difference from 3 g/l in the physical characteristics, whereas the KES-FB values indicated a significant loss of fabric hand in most PHVs with
the 5 g/l concentration level. Among different garment parameters, all four fabric types were relatively inappropriate for the men’s
slacks (MS) fabric due to the lower hand value of koshi required by the MS parameter. However, despite the relatively low
koshi values, high fukurami values required for men’s dress shirt (MWDS) resulted in the highest THV among the four garment
parmeters. The four fabric types, which represent the usage of four different wood pulps, in general seem to exhibit a higher
applicability to women’s winter thin dress (WWTD) than women’s winter suit (WWS) garment parameter. 相似文献

Chitosan is a natural nontoxic biopolymer used widely in various fields due to the antimicrobial activities. In this study,
the properties of polyester fabrics grafted with chitosan oligomers/polymers after being activated by atmospheric pressure
plasmas were evaluated. The antibacterial effect was most evident when the surface of fabrics was activated by atmospheric
pressure plasma for 60 to 120 seconds and grafted with chitosan oligomers. The modified fabrics also exhibited good biocompatibility.
This process can be applied to a large area and used to produce antibacterial polymer fibers. 相似文献
