Structural design and vertical wicking behavior of cotton roving-based materials for nutrient transport of indoor plant

The liquid transport capacity in a fibrous textile is of great crucial in comprehensively assessing the final moisture management. In this work, several materials were prepared based on cotton rovings by regulating some technological parameters such as twist and ply number, and the effects of the above key parameters on vertical wicking behavior of cotton roving-based materials were investigated. To effectively improve the wicking rate of materials, three hydrophilic schemes were introduced. The experimental results indicated that the maximum vertical wicking height was obtained when samples treated with a mixed solution of 1.5% JFC and 3% NaOH. Subsequently, several cotton roving-based materials were fabricated based on the optimized hydrophilic treatment. It was found that, the as-prepared materials exhibit a twist-reduced wicking effect, and a ply number-strengthen effect. Furthermore, the underlying mechanisms in the above two cases were unraveled. Finally, our prepared cotton roving-based materials served as a nutrient absorbing medium were demonstrated. Such work provides certain support for an in-depth understanding of wicking behavior of microporous textile structures.

Performance of recycled PET and conventional PES fibers in case of watertransport properties

In recent years the researches on liquid moisture transport properties of fabrics have great importance. Especially forthe sport garments, fabric structure should led liquid moisture to transfer from skin surface to the outer layers. Specialfibers and fabric structures were designed including channelled fibers and micro fiber productions to contribute highercapillary transport capability to the textile surface. Polyester fibers are used for this purpose frequently. Due to theincrease in the demand of sustainable textiles, production and consumption of recycled polyester fibers are increasingrecently. They are expected to have adequate mechanical properties to fulfil requirements. In this study, liquid moisturetransfer properties of the polyester and r-PET fabrics were investigated. For this purpose, knitted fabrics produced from100% polyester and 100% r-PET yarns were used. Dynamic liquid transport properties, capillary transfer property, dryingrate and water absorption capacity of these surfaces were measured. According to the results, it was concluded thatboth fabrics were identified as “good” by using “Moisture Management Tester”, in case of liquid moisture transferproperties. No significant difference was determined between water vapour permeability values. Static immersion test ishelpful in order to determine wettability for the identification of sensitive differences and as a conventional method,vertical wicking test is a good indicator while distinguishing capillarity differences. It was found that r-PET fabric hasbetter results than PES fabric, in case of absorption rate, wettability, drying rate and capillarity.

Effect of using Trilobal® polyester on the functional performance of fencing suit

Purpose The paper aims to use the Trilobal® polyester (Y cross-section) for producing fabrics suitable for fencing suits and evaluating their various properties. Design/methodology/approach Double weave structure was chosen to produce the samples by using six different face structures and two back structures divided into two groups according to the back structures. They were evaluated by their physical and mechanical properties such as tensile strength, puncture resistance, air permeability and humidity properties in horizontal and vertical wicking, drying rate and water vapor transmission. Findings Fencing sport recently is one of the most growing sports in the world, which necessitates special requirements and properties of fencing suit, either mechanical properties, which allow the easily and freely movement for the athlete, or the comfort properties that save the player’s effort and energy for a long time to improve his performance. Originality/value ANOVA test analysis showed highly significant results in some properties comparing back and face structures of the double weave fabric high correlation coefficient were found between packing density factor of produced fabric and the weft material types. The final results showed the produced sample that weaved with plain 1/1 for back structure and warp rib 2/2 for face structure achieved the best results, followed by the produced sample weaved with plain 1/1 for back structure and weft rib 2/2 for face structure compared with the other produced samples.

Wicking Properties of Men’s Quick-Dry Sportswear

In this study, the quick dry properties of summer men’s T-shirts of different brands (Nike, Adidas, Laishilong and Columbia) in Hong Kong market were explored by analyzing the wicking behavior. Laishilong was found to be the best sample in terms of vertical wicking for both short and long period. For the Nike fabrics, the wicking rate in courses direction was better than that in wales direction, whereas the vertical wicking of front body for Adidas was better than the back body. By contrast, Columbia performed the poorest in terms of vertical wicking for long period. With the help of this study, the general wicking properties of men’s quick-dry sportswear in the market can be compared which provide some idea to the consumer for product selection.

The Assessment of Finishing Properties on the Mass per Unit Area, Pilling, Bursting Strength, and Wicking Behavior of Polyester Weft-Knitted Jersey Fabric

Finishes bring an alteration to the physical and comfort properties of the textiles. That’s why various finishes are used to impart various functionalities to the fabric surface. However, it may also affect some properties. The purpose of this study is to investigate the effect of various finishes on pilling, mass per unit area, bursting strength, and wicking behavior of the polyester weft-knitted jersey fabric. Herein, 100% spun polyester weft-knitted plain jersey fabric was exposed to different finish treatments to check their effect on the some physical and comfort properties of the fabric like mass per unit area, pilling behavior, bursting strength, and wicking properties of the weft-knitted jersey fabric. The fabric used was knit from 24/1, 100% spun polyester yarn on the single knit circular knitting machine. The developed fabric was washed on Fong machine. Finishes are applied on fabric by “Monofort Stanter” machine. The resultant fabric was characterized by random tumble pilling tester, bursting strength tester, and wicking tester to analyze their pilling grade, bursting strength, and wicking behavior respectively. A significant increase has been found in wicking behavior, mass per unit area, and bursting strength of the fabric after finishing treatments. Moreover, the wicking finish shows the highest reduction in pilling grade from 3.5 to 2.5. Significant improvement has been observed in bursting strength by all finish’s treatment. However, wicking finish treatment results in the highest increase in bursting strength of 4.2%. Significant improvement has been observed in the vertical wicking speed of all treatment except silicon finish which significantly reduces vertical wicking rate. However, the wicking finish (Recipe E) shows the highest increase in wicking rate by 13.75 times as compared to grey fabric.

Investigation of temperature-responsive and thermo-physiological comfort of modified polyester fabric with Sericin/PNIPAAm/Ag NPs interpenetrating polymer network hydrogel

Stimuli-responsive polymers applied to traditional textiles have received widespread attention. In this work, a new type of polymer-modified polyester fabric was prepared with interpenetrating polymer network (IPN) hydrogel. The IPN hydrogel comprised of poly (N-isopropylacrylamide) (PNIPAAm), silk sericin (SS), and silver nanoparticles (Ag NPs). The presence of the IPN hydrogel on the surface of fibers can change the wettability of polyester fabric, in response to temperature. The thermal behavior of IPN hydrogel was characterized by differential scanning calorimetry (DSC) and thermogravimetric analysis (TG). DSC results indicated that the IPN hydrogel exhibits temperature-responsive behavior and the lower critical solution temperature (LCST) was around 32.9℃. The decomposition temperature of modified polyester fabric (400.5℃) was better than the original polyester fabric (335℃). TG results indicated that the polymer-modified fabric possessed higher thermal stability than the original polyester fabrics. The thermo-physiological comfort of modified polyester fabric was characterized by water contact angle and vertical wicking test. Above the LCST, the wettability of the polymer-modified polyester fabric would decrease because of the volume phase transition of IPN hydrogel. Moreover, the antibacterial activity of the modified temperature-sensitive fabric against Staphylococcus aureus and Escherichia coli was also investigated, and the antibacterial activity for both microorganisms exceeded 95%. This study provided a feasible route to fabricate the temperature-responsive textile with great antibacterial performance.

Effect of Weaving Structures on the Water Wicking–Evaporating Behavior of Woven Fabrics

Water transfer through porous textiles consists of two sequential processes: synchronous wicking–evaporating and evaporating alone. In this work we set out to identify the main structural parameters affecting the water transfer process of cotton fabrics. Eight woven fabrics with different floats were produced. The fabrics were evaluated on a specially designed instrument capable of measuring the water loss through a vertical wicking process. Each test took 120 min, and two phases were defined: Phase I for the first 10 min and Phase II for the last 110 min according to wicking behavior transition. Principal components and multivariate statistical methods were utilized to analyze the data collected. The results showed that Phase I dominated the whole wicking–evaporating process, and the moisture transfer speed in this phase varied with fabric structure, whereas the moisture transfer speeds in Phase II were similar and constant regardless of fabric structure. In addition, fabric with more floats has high water transfer speed in Phase I due to its loosened structure with more macropores.
