· The composites had a weight composition of 30% caroá and 70% unsaturated polyester with dimensions of 20×20×3 mm 3 and 20×20×6 mm 3. Water absorption tests were conducted by immersing samples in a distilled water bath and the water uptake was followed gravimetrically for different elapsed time.
Polyester fibers are normally hydrophobic, and resist the absorption of water into the fabric structure. This can lead to feelings of clamminess and discomfort, particularly in humid weather. In some instances this problem may be overcome by providing a fabric which comprises a blend of polyester and cellulosic material, such as cotton.

· OK, polyester has a moisture regain of 0,4 to 1% nylon has a moisture regain of about 4 to 8%. Spandex has a moisture regain of 1 to 1,5%. So spandex doesn't seem to add much in absorption capacity compared to nylon. Moreover, …
· polyester/lyocell combination, the water absorption, verticle wicking, transverse wicking and spreading areas are found to be high. Keywords: Bamboo charcoal, Lyocell, Micro polyester, Moisture management properties, Thermal conductivity, Tri-layer fabric 1 Introduction Fabrics are rarely worn as a single layer in
· Polyester adsorbs about 0.2 to 0.5 % water at 20 °C and 65 % r. h. - in dependence on its production process. The water adsorption correlates with the …
· Water absorption and transport properties of fabrics, including initial contact of liquid with a dry fabric, liquid wicking through a fully saturated medium and removal of liquid from a fabric is important during processing and in use. In this study, the water transport properties of four weft knitted polyester fabrics were comprehensively evaluated and it aims to select the …
Absorbent fabrics are hydrophilic, meaning they attract water. Water attraction is called hygroscopy. Natural fibers like cotton, hemp and bamboo are made of …
· Water absorption is the amount of liquid absorbed by a sample when it is completely immersed in water for 1 h. Measurement results of the water absorption are shown in Table 3. It follows from the table that the water absorption of the modified fabric increases by 6–26 %, and it increases with the duration of fluorination.

· The result shows wicking behaviour of modified polyester is higher than normal polyester. Water absorbency of modified polyester is higher than normal polyester. There is no significant difference in the fabric by varying the pick density. The study shows that the modified polyester has higher comfort than normal polyester fabrics.
Absorbent fabrics are hydrophilic, meaning they attract water. Water attraction is called hygroscopy. Natural fibers like cotton, hemp and bamboo are made of cellulose, whose sugar molecules can break water's surface tension so that it …
Main influencing factors of hydrophilicity of polyester fiber or fabric: (1) surface and section shapes of single fibers. Fiber surface with small concave convex or irregular shape of the fiber water absorption.This is because the smooth and complete surface structure of the fiber changes, not only makes the specific surface area increase ...
Water absorption was evaluated by the following equation according to "GB/T 21655.1—2008 Textiles—Evaluation of Absorption and Quick-Drying—Part 1: Method for ... The abrasion resistance of the pure common interlock polyester fabric is much better than that of the fabrics with honeycomb polyester, and the reasons are shown as in the ...
· Polyester fibers (PES) are the most consumed textile fibers due to their low water absorption; non-ionic character and high crystallinity. However, due to their chemical structure, the chemical interactions between polyester, finishing products, and dyes are quite challenging. We report on the use of ozone to modify the surface of polyester fibers with the goal of improving …
