Small-diameter vascular grafts fabricated from synthetic polymers have found limited applications so far in vascular surgeries, owing to their poor mechanical properties. In this study, cylindrical nanofibrous structures of highly oriented nanofibers made from polyacrylonitrile, poly (lactide-co-glycolide) (PLGA), polycaprolactone (PCL) and poly(vinyl acetate) (PVAc) were investigated. Cylindrical collectors with alternate conductive and non-conductive segments were used to obtain highly oriented nanofibrous structures at the same time with better mechanical properties. The surface morphology (orientation), mechanical properties and suture retention of the nanofibrous structures were characterized using SEM, mechanical tester and universal testing machine, respectively. The PLGA nanofibrous cylindrical structure exhibited excellent properties (tensile strength of 9.1 ± 0.6 MPa, suture retention strength of 27N and burst pressure of 350 ± 50 mmHg) when compared to other polymers. Mor...

Increasing issues of pathogen drug resistance and spreading pose a serious threat to the ability to treat common infectious diseases, which encourages people to explore effective technology to meet the challenge. Photodynamic antibacterial inactivation (aPDI) is being explored for inactivating pathogens, which could be used as a novel approach to prevent this threat. Here, porphyrin-embedded MOF material (PCN-224) with photodynamic effect was synthesized, then the PCN-224 nanoparticles (NPs) were embedded into PAN nanofibers with an electrospinning process (PAN-PCN nanofiber membrane). On the one hand, polyacrylonitrile (PAN) nanofibers help to improve the stability of PCN-224 NPs, which could avoid their leakage. On the other, the PAN nanofibers are used as a support material to load bactericidal PCN-224 NPs, realizing recycling after bacterial elimination. An antibacterial photodynamic inactivation (aPDI) study demonstrated that the PAN-PCN 0.6% nanofiber membrane processed 3.00 l...

The impact of card cylinder speed, card production rate and draw frame doubling on cotton yarn quality parameters was investigated by using the Box-Behnken experimental design. It was found that yarn tenacity, elongation and hairiness increase by increasing the number of draw frame doubling up to a certain level and then decrease by further increase in doubling. Yarn unevenness increased by increasing card production rate and total yarn imperfections increased by decreasing card cylinder speed and increasing card production rate.

The mechanical and comfort properties of polyester/bamboo and polyester/cotton knitted fabrics were studied. Four different ratios, P/B 65/35, P/B 50/50, P/B 35/65, P/B 20/80, P/C 65/35, P/C 50/50, P/C 35/65, P/C 20/80 of both blends were produced by mixing at the blow room stage. Then yarns of equal count Ne 20 were made on a ring spinning machine, and a knitted fabric was produced on a single jersey weft knitting machine. It was observed that by increasing bamboo and cotton fiber content in the blends, yarn breaking force and tenacity were decreased. Bursting strength, bending rigidity, and thermal resistance of the blended fabrics decreased by increasing bamboo and cotton fiber content in the blends, while air permeability and moisture management capability was found to increase with the increase in bamboo and cotton fiber content. No antimicrobial activity was shown by any of the P/B blended fabric, but to some extent, 100% bamboo fiber showed antibacterial activity against gram...

The study aims to present a relationship between air permeability of woven fabrics and their light transmission properties. Polyester / cotton (48:52) blended woven fabrics were utilized in the study. Air permeability is measured using the standard test method already established while the light transmission through the fabric is measured by means of two different methods. One method is based on measurement of light transmitted from a back lit fabric by means of a light sensor. The second method is based on image processing techniques which require a digital back lit image of fabric and an algorithm is applied to measure the amount of light transmitted through it. Results from both methods are compared and correlated with the air permeability and porosity of woven fabrics. Analysis shows that the results from former method have a stronger and more significant relationship with air permeability of woven fabrics comparatively.

ABSTRACT The aim of this study was to analyze and model the effect of knitting parameters on the air permeability of Cotton/Polyester double layer interlock knitted fabrics. Fabric samples of areal densities ranging from 315-488 g/m2 were knitted using yarns of three different cotton/polyester blends, each of two different linear densities by systematically varying knitting loop lengths for achieving different cover factors. It was found that by changing the polyester content in the inner and outer fabric layer from 52 to 65% in the double layer knitted fabric did not have statistically significant effect on the fabric air permeability. Air permeability sharply increased with increase in knitting loop length owing to decrease in fabric areal density. Decrease in yarn linear density (tex) resulted in increase in air permeability due to decrease in areal density as well as the fabric thickness. It was concluded that response surface regression modeling could adequately model the effect of knitting parameters on the double layer knitted fabric air permeability. The model was validated by unseen data set and it was found that the actual and predicted values were in good agreement with each other with less than 10% absolute error. Sensitivity analysis was also performed to find out the relative contribution of each input parameter on the air permeability of the double layer interlock knitted fabrics.

ABSTRACT The aim of this study is to model the effect of knitting parameters on the air permeability (AP) of polyester/cotton interlock fabrics. Fabric samples of areal densities ranging from 105 to 654 g/m2 were knitted using yarns of three different polyester/cotton blends, each of the three different linear densities by systematically varying knitting loop lengths for obtaining different cover factors. It was found that changing the polyester/cotton blend ratio from 65/35 to 52/48 and 40/60 did not have a statistically significant effect on the fabric AP. AP sharply decreased with decrease in knitting loop length owing to increase in fabric areal density. Increase in yarn linear density (tex) resulted in a decrease in AP due to increase in fabric thickness as well as the areal density. It was concluded that response surface regression modeling could adequately model the effect of knitting parameters on the fabric AP. The model was validated by unseen data-set and found that predicted and actual values were in good agreement with each other with less than 5% absolute error. Sensitivity analysis was also performed to determine the relative contribution of each input variable on the AP of the interlock fabrics.

The aim of this study was to investigate the effect of knitting parameters on the moisture management and air permeability of the interlock fabrics. Samples were produced at two different knitting gauges, each with three different stitch lengths. It was found that the fabric mass per square metre increases by increasing machine gauge and decreasing the stitch length, whereas the fabric thickness and porosity increase at these settings. It was further concluded that the loosely knitted fabric samples with higher amount of entrapped air exhibit good air permeability but poor moisture management properties.

The aim of this research is to study the effect of clothing manufacturing parameters, that is, stitch type, stitch density, sewing thread type and washing type on the dimensional stability of single jersey knitted garment. Single jersey bleached fabric, made from Ne 32 cotton combed ring spun yarn, was used to make 32 medium size crew neck T-shirts selecting two levels of stitch type, stitch density, sewing thread type and wash type according to the experimental design. After constructing the garments, four critical measurements of each garment, that is, body length, body width, across shoulder and sleeve length were measured. The constructed garments were divided into two equal groups. One group was washed with water and the other group was washed using a detergent. After washing, drying and tumbling, the same critical measurements of each garment were taken and the percent shrinkage was calculated. Analysis of data was done on responses of output variables against the input variab...

ABSTRACT In this study, six different woven samples were produced on air jet loom with two different weave designs (i.e. 3/1 twill and 1/1 plain), three different picking sequences (i.e. single pick insertion (SPI), double pick insertion (DPI) and three pick insertion (3PI)). All the woven samples were singed, desized, bleached and finished together at industrial scale, as a single lot. The effect of these factors on the wetting, wicking and air permeability (AP) of the fabric samples was analysed. It was revealed that the fabric weave design and picking sequence has statistically significant effect on fabric wetting time, water spreading speed and AP of the fabric. It was found that fabrics woven in twill weave design and with simultaneous 3PI give significantly better AP, shorter wetting time and better water spreading rate as compared to plain woven fabrics and those with double or SPI. It could be concluded that the thermophysiological comfort of woven fabrics may be significantly improved simply by selecting a suitable weave design and picking sequence.

ABSTRACT The aim of this study was to develop statistical models for the prediction of warp and weft crimp percentage of cotton woven fabrics. The developed models are based on the empirical data obtained from carefully developed 60 fabric samples with different yarn linear densities, fabric densities and weave designs. The predictability and accuracy of the developed models was assessed by correlation analysis of the predicted and actual crimp values of another set of 8 fabric samples which was not used for the development of models. The results show fairly good capability and accuracy of the prediction models.

Tensile strength has been accepted as one of the most important performance attributes of woven textiles. In this work, multiple linear regression models are developed by using empirical data for the prediction of woven fabric tensile strength manufactured from cotton yarns. Tensile strength of warp & weft yarns, warp & weft fabric density, and weave design were used as input parameters to determine warp- and weft-way tensile strength of the woven fabrics. The developed models are able to predict the fabric strength with very good accuracy. Warp yarn strength and ends per 25 mm are found to be the most dominant factors influencing fabric strength in warp direction while weft yarn strength and picks per 25 mm are most vital in weft direction.

The aim of this study was to analyse the effects of various fabric parameters on the thermal resistance, thermal conductivity, thermal transmittance, thermal absorptivity and thermal insulation of polyester/cotton double layer knitted interlock fabrics. It was found that by increasing fibre content with higher specific heat increases the thermal insulation while decreases the thermal transmittance and absorptivity of the fabric. It was concluded that double layer knitted fabrics developed with higher specific heat fibres, coarser yarn linear densities, higher knitting loop length and fabric thickness could be adequately used for winter clothing purposes.

Cotton is one of the most commonly used fibres for making knitwear. Some of the limitations of pure cotton knits include their tendency to shrink, relatively limited durability, and poor wash and wear properties. In order to overcome these limitations knitwear are also produced from polyester and cotton blends, however, at the cost of reduction in comfort properties. The objective of this study was to improve the thermo-physiological comfort properties of knits made from polyester/cotton (P/C) blends through simple chemical and biological treatments. The specimens of P/C knits were subjected to treatments with caustic soda solutions and the cellulase enzymes. It was found that the air permeability and perspiration management properties of P/C knits can be significantly improved by appropriate caustic treatment. However, the biological treatment with cellulase enzymes is comparatively less effective in making any improvement in the thermo-physiological comfort properties of P/C knits.

The aim of this study was to evaluate the effect of elastane material linear densities on lateral compression values (ankle and calf) in newly designed shape (V-shape) compression socks. For this purpose, three types of yarns: main yarn (MY), plating yarn (PY) and inlaid yarn (IY) were used. Each yarn contains elastane material as core with varying linear densities. Firstly, Machine adjustments were optimized to achieve special V-shaped compression socks according to fix leg size. All the yarns were installed simultaneously and evaluated for their impact on compression pressure value at different segments of leg. Total eighteen socks samples were developed and quantified for pressure exertion using MST MKIV, Salzmann pressure monitoring device. All samples were analyzed using ANOVA in MINTAB 16 software. Consequently, only two socks samples finalized acquiring pressure exertion values of 21 mmHg and 23 mmHg with graduation percentage of 76% and 74% simultaneously

Elastane percentage in the core-spun cotton yarn of a specific linear density can be affected in two ways: either by changing the elastane denier or the draft ratio. The purpose of this study was to find out whether different mechanical properties of fabrics woven from such yarns simply depend upon the elastane percentage or whether the method of achieving a desired elastane percentage has specific effects. It was found through regression analyses that both the elastane denier and the draft ratio are almost equally important for fabric tear strength and stretchability, whereas the fabric tensile strength is predominantly influenced by the elastane denier while the fabric recovery after stretch is mainly influenced by the elastane draft ratio.

ABSTRACT Silver-containing wound dressings are now commonly available with much publicised claims of antimicrobial activities against all kinds of pathogens including methicillin-resistant Staphylococcus aureus (MRSA). However, there are little or no credible reports on the control release agents for the minimum potent quantities of silver needed in dressings for antimicrobial purposes over time. This paper introduces a new biomaterial fibre made from natural polymers with an inbuilt ability to gel and absorb large quantities of pseudo exudates. Furthermore, the new fibre carries up to six times less silver than it is conventionally used in silver dressings and displays a very slow rate of release whilst maintaining full potency over time against known microorganisms including methicillin-resistant S. aureus. The paper concludes that the developed fibre has long-lasting antimicrobial and gelling properties comparable, if not better, than Acticoat AA and Aquacel Ag, two commercially available silver dressings.

UV radiations are high energy radiations present in sunlight that can damage human skin. Protection against these radiations becomes vital especially in those areas of the globe where UV index is quite high that makes the inhabitants more prone to dangerous effects of UV radiations. Clothing materials are good blockers of UV radiations, particularly when the fabric cover factor is high and/or the fabrics contain suitable UV blocking finishes. In this study, effect of application of aqueous and methanolic extracts of two different plants i.e. Achyranthes aspera and Alhagi maurorum on UV protection properties of cotton fabric was investigated. The results showed that the fabric samples treated with extracts of both the plants have excellent UV protection properties as indicated by their Ultraviolet Protection Factor. It was concluded that both the aqueous and methanolic plant extracts are very effective in blocking UVA and UVB radiations, when applied on cotton fabrics. The UV protection performance of Achyranthes aspera extracts was much better as compared to that of Alhagi maurorum, and methanolic extracts of both the plants outperformed the aqueous extracts in term of UV protection.

This study was conducted to develop an eco-friendly pigment colouration method in combination with functional finishing treatment for polyester/cotton blended fabrics. The advantages of pigment dyeing are manifold, however the rubbing fastness of colours in deeper shades is doubtful, hence it requires further exploration. The undertaken research focused on the assessment of colour fastness characteristics of polyester/cotton fabrics treated with pigment colourants and common functional finishes. The effect of finish type and concentration along with two different approaches of finish application were considered. As regards the effect of finishing techniques, the meta finishing treatments of dyed polyester/cotton fabrics with pigments, provided maximum dry rubbing fastness at both high and low concentrations of finish, while wet rubbing and wash fastness (staining) were found to be better in performance than post finishing method only at low concentration. The most favourable results regarding wet rubbing fastness of fabrics were attained by the treatment of durable water and oil repellent finish. The responses of soft polyurethane, water repellent (NUVA FD) and water/oil repellent (NUVA 3585) on dyed polyester/cotton fabrics were maintained at a good level of wash fastness (shade change). Moreover, desirable wet crocking and washing fastness of fabrics was achieved by incorporating fluorine dispersion (water repellent finish) directly in to the pigment formulations.

A new approach was investigated for appraising the fastness properties while maintaining/ upgrading the tensile strength of 100% cotton, light weight fabric samples, dyed with natural colourant of Marigold flower (Tagetes erecta). Various dyeing formulas planned with the aid of different dyeing auxiliaries utilized as mordants, cross linkers, finishing agents and UV absorbers were applied by pad-steam (two-bath-two-stage) dyeing procedure. All the recipes were exercised both as pre and post treatments. Pretty yellow fabric samples resulted from the experiments having better colour fastness, enviable K/S value and adequate tensile strength. Some of the mordants (such as FeCl 3 and Al 2 (SO 4) 3) produced samples of darker shades, entirely different from the yellow colour. The presence of CuSO 4 in the dyeing recipe produced sample with bright yellow shade. This mordant was excelled by all other dyeing auxiliaries in enhancing not only the colourfastness but also presenting greater colour strength (K/S value). Post treatment of a reactive UV absorber based on oxalinilide (UV-SUN) and fibre-reactive UV absorber Rayosan C (heterocyclic compound) imparted very good lightfastness (6 Blue Wool Standard). Crosslinking agent Fixapret CPF, methylolation product based on glyoxalmonourein resulted in remarkable improvement in crocking and light fastness of cotton. Fixative Albafix WFF (quaternary ammonium compound) was also found effective in acquiring very good rub fast cotton samples.
