Design and development of functional fabrics with dust- and sound- absorbing properties
Journal of Industrial Textiles, 2017
In an environmentally polluted environment, woven curtain fabrics that collect dust and pollen play an important health-protective role in interior decoration. However, devices or evaluation factors for measuring the dust adsorption ability of interior products have not been developed. To resolve this deficiency, we developed an apparatus that directly measures the dust adsorption and devised two test parameters (dust interrupting capability and fine dust adsorption capacity) for quantifying the dust adsorption. We also investigated the physical properties affecting the dust adsorption ability of fabrics with different denier weaves of air-textured yarns and draw-textured yarns, which adsorb dust in their fluffs and crimps, respectively. The air permeability and weight of the fabrics were strongly correlated with fine dust interrupting capability. The air permeability, dust adsorption, and interruption capability of the air-textured yarns largely depended on the loops formed by the overfeed rate in the weft direction. The strong sound-absorbing performance of the samples (especially at higher frequencies) was also obtained by loops, fluffs, and crimps of air-textured yarns and draw-textured yarns of fabrics. The best sound-absorbing performance was exhibited by S20, made from 760 D with many loops on the yarn surface.
Eco-friendly Treatment on Rib Knitting Fabrics Part I. Enhancement of antimicrobial performance
Current Science International, 2018
This work is devoted to impart some new functional properties to kitted cotton fabrics. To achieve this purpose, knitted cotton fabrics containing Lycra (3%, 7%) are treated using various natural compounds namely; nanoclay (NC), β-cyclodextrin (CD), chitosan (CH) and citric acid (CA). Some physical and chemical properties of the treated as well as untreated cotton fabrics are evaluated such as moisture regain, bursting strength, abrasion resistant and fabric density number. FTIR of the treated and untreated cotton fabrics was investigated. The biocidal activity of the said fabrics was performed. The color intensity and fastness to wash of dyed fabrics with both direct and reactive dyes were determined. The results proved that the fabrics performance and comfort of the treated fabrics were enhanced compared to the untreated one.
Effect of Different Pretreatment on Various Properties of Undyed and Dyed Jute Fabrics
Journal of Textile and Apparel, Technology and …, 2009
The jute fabrics were desized, scoured, caustic soda mercerized at room temperature (25-30 o C) and ammonia mercerized at -33 o C and bleached. Then the above fabrics were dyed with Procion orange MX-2R (Reactive dyes) dye applying by standard procedure to investigate the change in different properties like moisture regain, abrasion resistance and flexural rigidity etc. of dyed jute products. The x-ray analysis also have done of those undyed, differently treated-dyed jute fabrics. It is found that the moisture regain percentage of the jute fabrics increased after different treatments and the moisture regain percentage of dyed fabrics decreased in all the case. The number of abrasion rotations decreased on the treatment of the fabrics but ammonia treated samples gave better abrasion resistance than other samples. The differently treated dyed jute fabrics appear to decrease flexural rigidity or stiffness. It was also found that the brag space values (d) were 4.83 Å, 5.02 Å and 4.00 Å for normal bleached, ammonia mercerized-bleached and caustic soda mercerized-bleached fabrics respectively. The value of brag space (d) of those dyed fabrics of normal bleached, ammonia mercerizedbleached and caustic soda mercerized-bleached fabrics were found to be 4. 96 Å, 5.40 Å and 4.49 Å respectively. The brag space (d) values of the dyed fabrics are higher than undyed fabrics. The liquid ammonia ( -33 o C) treated jute fabrics shows better properties than other treated fabrics. So, it can be concluded that anhydrous liquid ammonia ( -33 o C) treatment and bleaching process before dyeing/printing is suitable for the diversification of jute for value addition.

Jute is the golden fibre of Bangladesh, we hold a large share in the international jute market. Traditionally jute fiber is used to produce yarn and woven fabric. The properties of jute fiber indicates that it can be successfully used to produce knitted fabrics. We can use jute instead of synthetic fibre.This work compares the major quality parameters of knit fabric – weight, fabric density, dimensional stability, spirality, bursting strength, abrasion resistance and pilling, thermal conductivity and wash fastness are tested and assessed the performance of jute in replace of synthetic or cotton for apparel concern. All results are better and acceptable as compare to ISO norms.
Effect of Finishing Treatments on the Functional and Mechanical Properties of Jersey Knitted Fabrics
2019
Abstract: Knitting has long been recognized as a leading method of forming fabrics for various end uses. So that many researches are being conducted to achieve the optimum of functional and mechanical properties of knitted fabrics. The aims of this study are twofold; firstly, Free formaldehyde cross-linking agent of cotton knitted fabrics were achieved through including some active agents, as functional agents, by using citric acid (CA), as an eco-friendly crosslinking agent, and Sodium hypophosphite monohydrate (SHP), as a catalyst, using the pad-dry-cure technique to impart difunctional eco-friendly finishing. , and secondly to study the influence of treatment finishing on the knitting parameters of jersey structure such as, loop length, tightness factor, stitch density, fabric weight and their effect on the mechanical properties of treated fabrics .
This research fills in the missing knowledge on the moisture management and air permeability of knitted fabrics developed using mixed cotton/antistatic polyester yarns with both antibacterial and antistatic behavior to enhance their functionality. The effect of the knit pattern, technical side, percentage of fiber mixture and treatment on water absorption capacity and time, relative water vapor permeability and resistance, and air permeability of developed fabrics was investigated. The 1x1 rib knit and half-Milano rib knit patterns were applied in each 4 percentages of cotton and antistatic polyester and 3 types of finishing to prepare 24 fabrics. The water absorption capacity for 1x1 rib knit fabrics was in the range of 182-231% and 162-237% for the half-Milano knitted fabric with the ∼20% increase when increasing the percentage of antistatic polyester or applying the treatment. The water absorption time depended on the pattern, the fabric treatment, and the percentage of the fiber mixture. The applied antibacterial treatment significantly prolonged the water absorption time of most of the dyed and softened samples. The 1x1 rib knitted fabrics showed significantly higher water vapor and air permeability than the half-Milano rib knitted fabrics. The relative water vapor and air permeability of the treated samples increased significantly with an increasing percentage of polyester.
COMPARATIVE STUDY OF CHEMICALLY AND MECHANICALLY SINGED KNIT FABRIC
Single jersey cotton knit fabric of 162 GSM was singed both chemically (enzyme treatment) and mechanically. Mechanically singed fabric exhibited more brightness and whiteness than chemically singed fabric and in the same manner chemically singed fabric resulted more yellowness than mechanically singed fabric. The color fastness to washing of the treated fabric experienced almost same results in both of the cases. On the other hand chemically singed fabric focused on prevailing more strength than mechanically singed one which was evaluated by bursting strength test. Eventually the CMC value of the chemically and mechanically singed, and then dyed, fabric remained within acceptable range. Microscopic view of the treated samples was also taken to capture the surface hairiness characteristics.

There is a heavy demand for cotton materials in diversified areas, and the research works on them are increased tremendously in the recent days. Chemical treatment of cotton cellulose without changing their fibrous form is a common practice in the textile industry. In this paper, cotton (woven and knitted) fabrics are selected and reacted with sodium hydroxide, morpholine or cellulase enzyme. The fabrics are then dyed by 6 different natural dyes: annatto, onion, pomegranate, indigo, myrobalan, barberry; and 2 synthetic dyes (reactive and sulphur dyes) and subsequently finished. The fabrics are then studied for their dyeing characteristics (K/S value), antibacterial activities, anti-odour and UV protection behaviour.

This paper investigates the changes observed after enzyme wash, acid wash, ice wash and pigment wash on different types of knit garment such as 100% cotton single jersey, single jersey slub, single Lacoste and terry fleece. For most of the cases property developed after any types of wash however, acid wash played a negative role. Therefore, Fabric weight increased around 5-10% after any types of mentioned wash except acid wash where weight decreased. Fabric shrinkage and spirality property degraded after wash. Besides, fabric perspiration, dry and wet rub properties remain constants. Moreover, the pH value found slightly acidic in nature. Finally, the pill remains same however, terry fleece fabric has a developed property. So, it can be ensured that there are significant changes after any types of wash and it has become possible for a wide range of design and wash variability.
Multi-functional Cotton Fabrics Using Nano-Technology and Environmentally Friendly Finishing Agents
Egyptian Journal of Chemistry
T io 2 NANOPARTICLES were prepared using sol-gel technique. The prepared nanoparticles were analyzed using transmission electron microscope (TEM). Cotton fabrics were treated using prepared TiO 2 nanoparticles in presence of citric acid and commercially flame retarding agent named Flovan CWF to produce cotton fabrics having multi-functional properties (anticrease, self cleaning, and flame retardant) using pad-dry-cure-method. The treated fabrics examined by several testing and analysis methods such as crease recovery angle (CRA), tensile strength (TS), elongation at break (El), whiteness index (WI), self cleaning through K/S measurement and flame retarding properties through thermogravimetric analysis (TGA). Results obtained reveal that the optimum condition for the preparation of multi-functional cotton fabric is by using the following formulation (6 % citric acid, 3 % TiO 2, 300g/l Flovan CWF) padded for pickup 100%, dried at 100 o C for 5min and cured at 160 o C for 3 min. The presence of TiO 2 nanoparticles on the surface of the fabrics was proofed using EDX and the fabrics were examined also using scanning electron microscope.
