“…One of the main reasons is the different interior chemical structures [2,4,5]. According to literature review [2,4,5], natural fibers in general would normally provide lower UPF values when compared to man-made fibers. 20 different yarns were chosen to be knitted into single jersey plain knit with different machine gauge setting.…”

“…Besides, the blended yarns and synthetic yarns were excelling in UV protection. The difference in sun protection properties of fibres is due to their different chemical structures ; result in variation in ultraviolet transparency [2,4,5].…”

“…Both natural and synthetic fibres, including cotton, wool, nylon, polyester and coolmax, which are the common used fibre types in textiles and apparels, are examined because UVR results in fibres being subjected to various degrees of damage and degradation [1]. The interaction of UV radiation between textile substrate, fibre types and its state affect a textile material in providing sun protection [2,3] and therefore, plain knitted fabrics with different fibre contents are studied in this paper.…”

Research works were carried out to understand the effects of different fibre content on the ultraviolet (UV) protection properties of plain knitted fabrics. Fibre type does affect the ultraviolet protection factor (UPF) of knitted fabric because of the different chemical structures. Generally speaking, coolmax fabric provided the best sun protection, followed by polyester fabric and blended fabric, while cotton fabric provided the poorest sun protection.

“…[ 6 7 ] A retroperitoneal location of the biliary collection or a chronic biloma is a rarely reported complication of CBD perforation. [ 2 8 – 10 ] Very few cases of CBD rupture with retroperitoneal biliary collections have been reported previously and have usually been due to iatrogenic injury, postoperative biliary stricture, or choledocholithiasis. [ 1 11 ] Unlike our case, the majority of these cases have been reported in adults.…”

Rupture of the common bile duct (CBD) in a child secondary to choledocholithiasis is a rare event. In this article, the authors describe a child who presented with an acute abdomen due to CBD rupture, with subsequent acute retroperitoneal fluid collections, all diagnosed preoperatively on CT scan. The aim of this article is to show the pathways that such collections can take in the retroperitoneum.

“…In order to improve durability, UV-absorbers of the ''reactive type'' contain reactive groups which could form covalent bonds with cellulose after fixation on this fiber was developed in recent years [11][12][13][14][15]. In this experiment, a new reactive UV-absorber (4-(4,6-dichloro-1,3,5-triazin-2-yloxy)-2-hydroxyphenyl) phenyl)-methanone was synthesized by connecting reactive 2,4,6-trichlorotriazine to 2,4-dihydroxybenzophenone.…”

A modified benzophenone UV-absorber containing reactive group (4-(4,6-dichloro-1,3,5-triazin-2-yloxy)-2-hydroxyphenyl)phenyl)methanone (UV-DTHM) has been prepared in good yield from the nucleophilic substitution reaction of 2,4-dihydroxy benzophenone with 2,4,6-trichlorotriazine, catalyzed by 1.3 equiv. NaOH. The most favorable reaction conditions (the catalyst dosage, the mole ratio of the reactants, and reactive time) were selected. The compound was characterized by IR spectroscopy, 1 H NMR, 13 C NMR, mass spectrometry, elemental analysis, and single crystal X-ray diffraction. The crystal monoclinic, space group C c with the unit cell parameters a = 3.987(2), b = 30.688(16), c = 12.423(6) Å and a = 90.00, b = 92.117(15), c = 90.008, Z = 4, R = 0.0620. wR(F 2 ) = 0.1589. The crystal structure reveals that 2,4,6-trichlorotriazine is boned to 4-seat hydroxyl of 2,4-dihydroxy benzophenone and a intramolecular hydrogen bond is formed with hydrogen of 2-hydroxyl and oxygen of carbonyl group. Moreover, thermogravimetric analysis (TGA) of UV-DTHM was studied, showing two distinct endothermic peaks at temperatures of 281.5 and 358.5°C. The molar absorption coefficient of UV-DTHM is 1.6 9 10 4 and 6.3 9 10 3 at 268 and 330 nm, respectively, and shows excellent ultraviolet absorption property.Electronic supplementary material The online version of this article (
