Study on Moisture Management Properties of Cotton/Polyester Knitted Fabrics Reference
Comfortability of a fabric is achieved by improving the moisture management behavior of the knitwear. In our study, the moisture management behavior of polyester and cotton fibers blended in 100:0, 50:50, and 0:100 ratios in four different structures such as single jersey, cross tuck, cross miss, and twill at two different loop lengths, 0.29 and 0.32 cm, were studied. Objective fabric tests were conducted to analyze the thermal properties of various knitwear. The results clearly proved that the knit fabric made of 100 % polyester has better moisture management behavior and a considerable level of comfort. Therefore, polyester can be applied to active sportswear fabrics. The structure of the fabric and the length of the loops in the fabric further affect the moisture management behavior. The cross-stitch 100 % polyester knit fabric with a loop length of 0.32 has excellent moisture management behavior, which provides excellent moisture management property compared with all other samples.
Quality Improvement of Wool Fabric Using Protease Enzyme
Environment and Ecology Research, 2014
Wool is a fiber from the fleece of domesticated sheep. The scaly structure of wool is responsible, to a great extent, for the tendency of wool to felt and shrink. Chlorination is a commonly used process to modify the scales of wool fibers with the purpose of providing resistance to felting and shrinkage but this process shows a number of drawbacks which forced to search for an ecologically clean alternative. There have been many attempts to replace this chlorine process by an environmental friendly process that would similarly degrade the scales. Enzyme processing is one of them that has come to forefront in the textile processing units and made processing more eco-friendly. In the present study an attempt was made to treat the wollen fabric with different concentrations (1, 2, 3, 4 and 5g/l) of Protease enzyme and observed the effects on physical properties including hand of the fabric, weight loss, Scanning Electron Microscope (SCM) test, absorbency, pilling, tensile strength, and fabric drape, dyeability as well as colour fastness properties of woolen fabrics. The control, scoured and enzyme treated samples were also tested and compared. All the samples were dyed with acid dye to check the effect of enzymatic degumming on dye ability of wool fabric. The dyed fabrics were subjected to testing for various colorfastness properties including light, washing, crocking and perspiration. Untreated wool fiber showed fair handle, no absorbency (60 seconds), rough and sharp scales on the surface of fiber, however enzyme treatment with different concentrations wool fabric showed improvement in softness, slight weight loss (6.31%), smoother surface scales, improved absorbency (minimum 45 seconds) and drapability. Treatment with protease enzyme brought improvement in the physical and colorfastness properties of wool fabric. Among all the concentrations of protease enzyme, 4 g/l concentration was found to be best.
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.
The comfort of sport wear has been studied widely on the level of textile construction, due to consumers are becoming more conscious for the comfort of the apparel that they are wearing. As a result, the interest in plasma techniques attracted the concern of many researchers to explore the outstanding properties added to the materials after plasma treatment. In the current investigation, the direct chemical and pre-plasma treated Polyester/Lycra fabrics were produced. For the chemical treatment, The polyester/lycra fabrics with dissolution of regeneration cellulose in NaOH/Thiourea/urea aqueous solution was used. The effect of direct chemical and pre- plasma treatments has been studied on SEM and Moisture vapor, liquid water transfer MMT .
Moisture Management Performance of Multifunctional Yarns Based on Wool Fibers
Advanced Materials Research, 2010
Blends of wool and moisture management fibres such as Coolmax and Finecool have been prepared to produce innovative yarns with specific functionalities. These yarns have been used to produce knitted fabrics and their performance was evaluated, including vertical and horizontal wicking. The influence of wool fibre proportion on the performance of each blend is analyzed. It is observed that the Coolmax based fabrics show the best capillarity performance, and the wool fibre based fabrics show lower water absorption performance.
The comfort is undoubtedly the most important human attribute depends upon the moisture transport which in turn depends on the moisture transport behavior of the knitted fabric. Moisture transport is the transfer of liquid water capillary interstices of the yarns and depends on the wettability of fiber surfaces, as well as the structure of the yarn and fabric. Because of its good water absorption property, cotton is often used for next-to-skin wear such as t-shirts, underwear, socks. All these are known as``as``moisture management`` which means the ability of a textile fabric to transport moisture away from the skin to the garment's outer surface in multi-dimensions and it is one of the key performance criteria in today's apparel industry since it has a significant effect on the human perception of moisture sensations. In order to study, plated knitted fabric for socks were knitted as plated single jersey in the same production conditions, from different types of yarns, prod...

The thermal-wet-comfort characteristic of fabrics is primary to clothing for human bodies. The comfort aptitudes in the fabrics increase the significance of attire and are gaining more interest in the global market. Therefore, the purpose of this study is to analyze the influence of finishing patterns and fabric structure parameters on the comfort performance, air permeability, wicking effect, one-way water transport properties and thermal-physiological properties of unidirectional water transport knitted polyester fabrics. Eight samples are developed by hydrophobic finishing, which possessed good moisture management properties. The result implies that with the intensity of pores, there is an increase in the capillary effect of moisture absorption and transportation in the fabrics. Further, the escalation of the hydrophilic area to a hydrophobic area and regularity in the finishing pattern make the fabrics better in performance for unidirectional water transmission and thermal-wet c...
IJERT-Moisture Management Study on Inner and Outer Layer Blended Fleece Fabric
International Journal of Engineering Research and Technology (IJERT), 2012

It is sometimes more important than the aesthetic properties when the garments are wearing next to skin. Among all the comfort properties, good absorption and easy drying is one of the major requirements. When we do some physical work, we sweat; garments should absorb this sweat quickly and transport it to the outer surface of the garment. From the outer surface, sweat (or water to be precise) should be evaporated quickly to keep the body dry and cool. All these desired phenomena come under one technical term, called "moisture management". Moisture flow through blended material (fleece knitted fabric inner and outer layer blended) is a complex phenomenon. Clothing should possess good liquid moisture transmission property, for providing the thermo physiological clothing comfort. The clothing should take up the moisture from the skin as well as transmit it to the atmosphere. Higher hydrophilicity and micro denier of a material is known for good absorption and transport of liquid moisture, but how it really helps to transmit the moisture, have been studied in this work. Super micro polyester (288 filament), Polyester (34 filament), cotton and modal have been chosen as different blending fibers and 10 fabrics with different blend proportion fabrics were developed. Moisture management property of the fabrics was examined using a MMT instrument. From the experimental result it has been observed that, water absorbency and water spreading rate of the fabric increases with the increase in number of hydrophilic group in the material and multi denier of the filaments. KEY WORDS Moisture management test, fleece knitted fabric, multi filament polyester yarn, cellulosic fibre yarn, inner and outer layer fabric blend.

This study reports on an experimental investigation of physical properties on the textile thermal comfort. Textile properties, such as thickness, relative porosity, air permeability, moisture regain, thermal conductivity, drying time and water-vapour transmission rate have been considered and correlated to the thermal and vapour resistance, permeability index, thermal effusivity and moisture management capability in order to determine the overall comfort performance of underwear fabrics. The results suggested that the fibre type, together with moisture regain and knitted structure characteristics appeared to affect some comfort-related properties of the fabrics. Additionally, thermal sensations, temperature and skin wetness predicted by Caseto Ò software for three distinct activity levels were investigated. Results show that the data obtained from this model in transient state are correlated to the thermal conductivity for the temperature and to Ret, moisture regain and drying time for the skin wetness. This provides potential information to determine the end uses of these fabrics according to the selected activity level.
