Aesthetic properties of fabrics have been considered as the most important fabric attribute for years. However, recently there
has been a paradigm shift in the domain of textile material applications and consequently more emphasis is now being given
on the mechanical and functional properties of fabrics rather than its aesthetic appeal. Moreover, in certain woven fabrics
used for technical applications, strength is a decisive quality parameter. In this work, tensile strength of plain woven fabrics
has been predicted by using two empirical modelling methods namely artificial neural network (ANN) and linear regression.
Warp yarn strength, warp yarn elongation, ends per inch (EPI), picks per inch (PPI) and weft count (Ne) were used as input
parameters. Both the models were able to predict the fabric strength with reasonably good precision although ANN model demonstrated
higher prediction accuracy and generalization ability than the regression model. The warp yarn strength and EPI were found
to be the two most significant factors influencing fabric strength in warp direction. 相似文献

In order to meet the required strength of a fabric, selection of yarn is difficult because tensile strength of woven fabric
depends upon a number of factors. Still, the manufacturers have to use hit and trial method in order to select the yarn for
the required tensile strength of fabric. This study was carried out to develop regression equations for the prediction of
yarn tensile strength suitable for the predefined strength of cotton woven fabrics. These equations were developed by using
empirical data obtained from two hundred and thirty four fabric samples prepared under a systematic plan with different constructions.
Prediction proficiency and precision of these regression equations were evaluated by correlation analysis of the predicted
and actual warp and weft yarn strength values of another set of thirty six fabric samples. The results show a very strong
prediction precision of the equations. 相似文献

This study was aimed at developing statistical models for the prediction of tensile strength of warp and weft yarns required
for attaining a pre-defined strength of PET/Cotton blended woven fabrics. The models were developed based on the empirical
data obtained from carefully developed 234 fabric samples with different constructions using 15, 20, and 25 tex yarns in warp
and weft directions. The prediction ability and accuracy of the developed models were assessed by correlation analyses of
the predicted and actual warp and weft yarn strength values of another set of 36 fabric samples. The analyses showed a very
strong ability and accuracy of the developed statistical prediction models. 相似文献

The aim of this study was to model the air permeability of polyester cotton blended woven fabrics. Fabrics of varying construction parameters i.e. yarn linear densities and thread densities were selected and tested for air permeability, fabric areal density and fabric thickness. A total of 135 different fabric constructions were tested among which 117 were allocated for development of prediction model while the remaining were utilized for its validation. Four variables were selected as input parameters on basis of statistical analysis i.e. warp yarn linear density, weft yarn linear density, ends per 25 mm and picks per 25 mm. Response surface regression was applied on the collected data set in order to develop the prediction model of the selected variables. The model showed satisfactory predictability when applied on unseen data and yielded an absolute average error of 5.1 %. The developed model can be effectively used for prediction of air permeability of the woven fabrics. 相似文献

The aim of this study was to understand the failure mechanism of two dimensional dry fabric structure considering yarn sets
and interlacements. For this purpose, data generated on air-entangled textured polyester woven fabric under the simple tensile
load and analyzed by developed regression model. The regression model showed that warp and weft directional tensile strengths
of satin fabric were higher than those of plain and rib fabrics in unravel sample. This might be related to the number of
interlacements of the fabrics. There was not a considerable difference between warp directional tensile strength of ravel
and unravel satin fabrics, whereas weft directional tensile strength of ravel satin fabric decreased rapidly with respect
to its unravel form. The satin fabric showed the highest warp directional tensile strength among the others. The lowest weft
directional tensile strength was received from ribs fabric. In semi-ravel sample, all fabrics showed low warp and weft directional
tensile strength values except in plain fabric. Warp directional tensile elongation of plain fabric was the highest in unravel
sample. Satin fabric showed the highest warp directional tensile elongation in the ravel sample. Warp directional tensile
elongations of all the fabrics in the semi-ravel sample became low. Weft directional tensile elongation of satin fabric was
the highest in unravel sample. In addition, satin and plain fabrics showed the highest weft directional tensile elongations
in the ravel sample. Weft directional tensile elongations of all the fabrics in the semi-ravel sample became low except in
ribs fabric. 相似文献

A modified ring spinning technique has been recently developed by incorporating false twisting devices into the conventional ring frame. Its application on the coarser yarn counts (7–32 Ne) showed notable advantages in modified yarn and fabric performance. More recently, it was noted that this technique can also be applied for producing finer cotton yarns. Thus this paper aims to carry out a systematic study of the physical properties of the finer modified yarns (80 Ne) and woven fabrics with respect to the conventional ones. Physical properties of conventional and modified single yarns were evaluated and compared. These two types of single yarn were used for the production of woven fabrics. Moreover, the above two types of single yarn were also plied and used for the production of woven fabrics under a commercial condition. All woven fabrics were assessed in terms of fabric tensile strength, tearing strength, abrasion resistance, fabric weight, and air-permeability as well as other fabric performance measured by the Kawabata Evaluation System (KES). Experimental results showed that finer modified yarns and fabrics exhibit higher strength, lower hairiness, and improved abrasion resistance, slightly better compression property, and smoother surface with relatively larger thickness. 相似文献

In this study, polyester and polypropylene staple fibers were selected as the raw material, and then processed through roller-carder,
cross-lapper and needle-punching machine to produce needle-punched non-woven fabrics. First, the experiment was planned using
the Taguchi method to select processing parameters that affect the quality of the needle-punched non-woven fabric to act as
the control factors for this experiment. The quality characteristics were the longitudinal and transverse tensile strength
of the non-woven fabric as well as longitudinal and transverse tear strength. The L18 (21×37) orthogonal array was selected for the experiment as it offered an improvement on the traditional method that wastes a lot
of time, effort and cost. By using the analysis of variance (ANOVA) technique at the same time, the effect of significant
factors on the production process of needle-punched non-woven fabrics could be determined. Finally, the processing parameters
were set as the input parameters of a back-propagation neural network (BPNN). The BPNN consists of an input layer, a hidden
layer and an output layer where the longitudinal/transverse tensile and tear strength of the non-woven fabric were set as
the output parameters. This was used to construct a quality prediction system for needle-punched non-woven fabrics. The experimental
results indicated that the prediction system implemented in this study provided accurate predictions. 相似文献

The aim of this study was to compare the response surface regression and adaptive neuro-fuzzy models for predicting the bursting strength of plain knitted fabrics. The prediction models are based on the experimental data comprising yarn tenacity, knitting stitch length and fabric GSM as input variables and fabric bursting strength as output/response variable. The models quantitatively characterize the non-linear relationship and interactions between the input and output variables exhibiting very good prediction ability and accuracy, with ANFIS model being slightly better in performance than the regression model. 相似文献

The woven fabric graphics designed with available computer aided design (CAD) systems using different colored warp and weft
yarns look quite different from the appearance of their actual fabrics. To enhance the visual effects of designed woven fabric
graphics, this paper reports a modified CAD woven fabric system, which allows users to design a fabric using parameters including
fabric weaves, yarn number, yarn material, fabric count, crimp shape of interwoven yarns, and illumination. This enhanced
system can design both yarns and fabrics, and consider the transitional color effect around interweaving points of warp and
weft yarns. Its simulation image quality of woven fabrics has been greatly improved, and several textile mills and universities
are currently using this woven fabric design system. 相似文献

3D woven composites provide efficient delamination suppression, enhanced damage tolerance, superior impact, ballistic and blast performance characteristics over 2D fabric laminates. At the same time, this type of composites, having practically straight in-plane fibers, show significantly better in-plane stiffness and strength properties than respective properties of conventional composites. But, how the in-plane elastic and strength characteristics of this type of fabrics compare with respective in-plane properties of equivalent 2D woven fabrics. This paper presents a comprehensive experimental study of the comparison of in-plane tensile, bending, crimp interchange properties of UD, 2D, 3D orthogonal, 3D angle-interlock and 3D warp interlock multi-layer structures woven from E-glass tow. The results depict that the 3D woven fabrics have considerably superior mechanical properties with much lesser crimp compared to 2D fabrics. 相似文献

The aim of this study is to analyze and determine the off-axis tensile properties of air-entangled textured polyester fabrics
based on unit cell interlacing frequency. For this purpose, continuous filament polyester air-entangled textured yarn was
used to produce plain, ribs and satin woven fabrics. The fabrics were cut from the warp direction (0°) to weft direction (90°)
at every 15° increment, and tensile tests were applied to those of the off-axis samples. The strength and elongation results
were introduced to the statistical model developed, and regression analyses were carried out. Hence, the effects of off-axis
loading and interlacement on the directional tensile properties of the fabric were investigated. The regression model showed
that off-axis loading influences fabric tensile strength. On the other hand, interlacement frequency is the most important
factor for fabric tensile elongation. The results from the regression model were compared with the measured values. This study
confirmed that the method used in this study as can be a viable and reliable tool. Future research will concentrate on multiaxially
directional fabric and the probability that it will result in homogeneous in-plane fabric properties. 相似文献

An objective pilling evaluation method has been developed using image analysis and artificial neural network. Pilling parameters obtained in the previous study were used as the input values for neural network. A total of 9 data sets including 5 standard grades and 4 interpolated intermediate grades were used for training the network. Nine samples were prepared to verify the validity of the trained network in comparison with the subjective evaluation results. 18 woven and 12 knitted samples were tested to investigate the effect of the fabric structure on the performance of the network. Finally, 55 woven fabric samples were tested to evaluate the performance of the newly developed method and it was proven to be suitable for the evaluation of pilling grade especially for woven fabrics. 相似文献

Tearing strength is one of the most important and critical properties related to durable press finished cotton woven fabric. In the past, modelling of tearing strength of cotton woven fabrics was based on untreated cotton woven fabric but not in durable pressed finished fabric. In this paper, a mathematical model was established to demonstrate the tearing strength mechanism of durable press finished cotton woven fabrics by dimensional analysis based on yarn diameter, cover factor, Young’s modulus and fabric elongation. The proposed model agreed well with experimental results and the proposed model can be used for optimizing durable press finishing process of cotton woven fabric. 相似文献

The aim of this study is to develop new pattern denim fabrics and characterize the mechanical properties of these fabrics after abrasion load. Furthermore, tensile and tear strengths of these fabrics have been analysed by using the Artificial Neural Network (ANN) and statistical model. All denim fabrics were first abraded and subsequently tensile and tearing tests were applied to the abraided fabrics seperately. Actual data generated from the tests were analyzed by ANN and regression model. The regression model has shown that tensile strength properties of the abraded large structural pattern denim fabrics are generally low compared to that of the small structural pattern and traditional denim fabrics. On the other hand, when the abrasion cycles are increased tensile properties of all denim fabrics are generally decreased. Tearing strength of weft and warp in the abraded large structural pattern denim fabrics are between small structural pattern and traditional denim fabric. On the other hand, when the abrasion cycles are increased tearing strength properties in the weft and warp for all denim fabrics are generally decreased. The results from ANN and regression models were also compared with the measured values. It is concluded that almost all values from ANN are accurately predicted compared with those of the regression model. Therefore, we suggest that both methods can be used in this study as viable and reliable tools. 相似文献

This paper focuses on the reflectance prediction of colored (unicolored) fabrics considering relationship between fractional reflectance values and cover factors of fabrics woven from polyester yarns. A novel equation for the calculation of relation between fractional reflectance and cover factor was proposed and usage of the equation was assessed by reflectance measurements. 48 dyed polyester fabrics having different constructional parameters were used and fabrics differed from each other by their cover factors. Warp yarn type and count, warp density and warp yarn twist were the same but weft yarn count, weft yarn fiber count and weft density were different for the fabrics in experimental sub-groups. The reflectance measurements were conducted on the dyed fabric samples as well as on the individual yarn systems (warp and weft) of the same fabrics. The proposed equation was tested according to different fabric constructional parameters and reasonable results with the experimental data were obtained. The possibilities of general use of derived mathematical relations between theoretical and measured reflectance values were researched. The relation obtained was used to explain the effects of different constructional parameters on reflectance behavior of fabric surfaces. 相似文献

A new production method for figured fabric has been developed. The figured fabric generated in this study is a plain weave
piled fabric and it shows the same figure on both sides unlike those fabrics woven on dobby or jacquard looms. It is woven
by a specialty yarn called the chenille yarn which is obtained by separating each warp of a base fabric woven in leno structure.
The base fabric is woven by inserting different colored weft each time in a certain sequence arranged according to the target
figure image. A CAD software and a computerized controller have been developed to control all the motions of a conventional
rapier loom and to handle the numerous weft insertion schedule efficiently. 相似文献

This paper reports an investigation on the predictability of bending property of woven fabrics from their constructional parameters
using artificial neural network (ANN) approach. Number of cotton grey fabrics made of plain and satin weave designs were desized,
scoured, and relaxed. The fabrics were then conditioned and tested for bending properties. Thread density in fabric, yarn
linear density, twist in yarn, and weave design were accounted as input parameters for the model whereas bending rigidity
in warp and weft directions of fabric formed the outputs. Gradient descent with momentum and an adaptive learning rate back-propagation
was employed as learning algorithm to train the network. A sensitivity analysis was carried out to study the robustness of
the model. 相似文献

The tensile properties of air-entangled textured polyester single and multiple yarn ends before and after weaving were analyzed.
The effects of weaving process considering fabric unit cell interlacement and number of yarn ends were evaluated by regression
model. For this purpose, plain, ribs and satin woven fabrics were produced. The yarns were raveled from fabrics, and the tensile
tests were applied to these yarns. The developed regression model showed that the number of interlacement and crimp ratio
on the warp and weft yarns influence their tensile strength. Tensile strength of raveled yarns decreased compared to that
of the bobbin yarn due to the effect of weaving process. This property degradation on the ravel yarns considered process degradation.
Generally, when the number of warp and weft yarn ends increases, the warp and weft yarn tensile strengths for each fabric
type decrease, whereas the warp and weft yarn tensile elongations slightly increase. The results from regression model were
compared with the measured values. This study confirmed that the method in the study can be a viable and reliable tool. The
research finding could be useful those who work on preform fabrication. 相似文献

Cellulase is useful for bio-polishing cotton fabrics which enhances their aesthetic performance instead of stonewashing process. Torque-free ring spun process is a widely used technique to produce newly low-twist and balanced torque yarns with soft hand. In this paper, denim fabrics woven with torque-free ring spun yarn and conventional ring spun yarn respectively were treated with cellulase under the same condition and their fabric handle, expressed as low stress mechanical properties, such as tensile strength, bending, shearing, compression and surface performance were investigated by Kawabata Evaluation System for Fabric (KES-F). After cellulase treatment, both denim fabrics revealed better flexibility, elasticity recovery, raised shearing stiffness, fluffier and improved smoothness. While torque-free ring spun yarn made denim fabric showed a better fabric handle than conventional ring spun yarn made denim fabric. 相似文献

In this study, electromagnetic shielding characteristics of woven fabrics made of hybrid yarns are investigated. For this
purpose, initially the hybrid yarns containing stainless steel wire are produced with hollow spindle covering technique, and
then eight different fabric samples are produced using these hybrid yarns. Electromagnetic shielding values of fabric samples
are determined by a test set up based on enclosure measurement technique. Measurements are made in the frequency range of
30 MHz-9.93 GHz. Test results show that woven fabric samples investigated in this study have 25–65 dB electromagnetic shielding
effectiveness for incident frequency. It was also shown that the direction, density and settlement type of conductive hybrid
yarn in fabric structure are important parameters affecting electromagnetic shielding characteristics of woven fabrics. 相似文献
