A study of the modelling and characterisation of compression garments for hypertrophic scarring after burns. Part 2: characterisation of compression garments

Compression therapy is the universally accepted treatment for the management of hypertrophic scarring after severe burns. A review of the type of treatments for burns and type of compression garments commercially available is discussed in Part 1 of this paper (Anand, Kanchi Govarthanam, & Gazioglu, in press). A refined model was also designed to predict the sub-garment pressure more accurately, irrespective of the shape and size of the limb (see Part 1, in press). The thermophysiological properties of the compression garment provide comfort by preserving body temperature and moisture output close to their normal levels. In this study, the dimensional, mechanical and thermophysiological properties of four fabrics procured from different sources were thoroughly studied and compared. The study was aimed at the determination of their suitability to be utilised for the management of hypertrophic scarring. It was established that one of the fabrics investigated possessed superior properties in comparison to the other three fabrics. It was also demonstrated that the characteristics of this particular fabric can be further enhanced for its suitability for use as a compression garment for this specific area of application.

Sports protective elastic knits: structure design and property evaluations

Abstract

Elastic knits are one textile that have a high extensibility, which helps to restrain the body and attain both effects in terms of health protection and body sculpture. These qualities make elastic knits a great candidate to be used in the sportswear textile industry. However, elastic knits have a compact structure, which causes discomfort, such as low thermophysiological comfort and low skin comfort, and some humid area also causes skin allergy. In this study, a crochet machine is used, while the knit patterns and rubber thread ratios are changed to improve the air permeability, thereby examining the optimal parameters of elastic knits that are suitable for the use as sports textiles. The test results show that changes in the knit patterns and rubber thread ratios have negative influence on the mechanical properties of elastic knits, including a 30–54% decrease in tensile stress, a 33–55% decrease in tear strength, a 1–2% decrease in elastic recovery rate, and a 10–24% decrease in bursting strength, but significantly improve the air permeability by 58–150%. The mechanical properties of elastic knits decrease as a result of decreasing rubber thread ratio, but still remain qualified standard required by the application fields.     

Comfort properties of bamboo/cotton blended knitted fabrics produced from rotor spun yarns

The comfort characteristics of bamboo/cotton-blended knitted fabrics made from rotor-spun yarns were studied in this research work. Five different blend proportions namely 100% bamboo, 100% cotton, 50:50 cotton:bamboo, 70:30 cotton:bamboo and 30:70 cotton:bamboo were used to produce rotor-spun yarns of 30^sNe_c. The yarn samples developed out of these different blend proportions were evaluated for yarn strength and elongation, yarn unevenness, yarn imperfections and used to produce single-jersey-knitted fabrics. All the fabric samples were dyed and finished. Fabric samples were evaluated for geometrical properties such as course/inch, wales/inch, stitch density and thickness apart from measuring comfort properties such as airpermeability, thermal conductivity, thermal resistance and water vapour permeability. The results indicated that 50/50 bamboo/cotton-blended knits have comparable fabric quality in terms of comfort properties with respect to 100% bamboo fabrics.

图像变换在多臂织物组织设计上的应用

传统的织物组织设计是通过对织物组织的穿综、纹板的修改来设计新组织,它要求设计者具有很好的设计经验,而且需要设计者通过鼠标以逐点点击的方式来设计新组织。基于图像变换的技术理论,提出了一种与传统设计不同的方法,从现有的织物组织图像出发,根据图像的扭曲、错切、剪贴等变换原理,对组织图像进行变换,再对变换后的组织图像进行识别,得到具有不同变换特征的新组织。通过选定不同的变换方法和参数,可以在短时间内由一个现有组织变换出多个新组织,操作简单,设计效率高,为多臂织物组织设计提供了一条有效的设计途径。     

An investigation of thermal comfort properties of Abaya woven fabrics

Abaya is a traditional Muslim woman’s outer garment. It is black in colour, and must be worn over the normal day-to-day clothing according to Islamic law. It is mandatory to wear Abaya in Arabian Gulf countries irrespective of the outside environmental temperature, which can be up to 50°C. Having many layers of clothing including Abaya makes it extremely uncomfortable for the wearer in a hot environment. Thermal comfort performance is, therefore, essential for fabrics used for Abaya. This study investigated some commercially available woven Abaya fabrics for thermal resistance, air permeability, thermal comfort, vapour resistance and fabric structural and surface properties. The results indicated that the Abaya fabrics with different weave structures, fibre composition and fabric weight have greater influence on the fabric thermal comfort performance.     

几种不同组织结构的衬衫面料保形性研究

根据常见的衬衫面料组织结构,使用JC9.7 tex纱线设计了6种不同组织结构的面料,研究不同组织结构对织物保形性的影响。对面料的保形性(尺寸稳定性、抗折皱性、外观平整度、抗起毛起球性、顶破性、悬垂性)及舒适性(透气、透湿性)进行了测试。结果表明:组织结构对织物的折皱回复角、外观平整度等级、顶破强力、透湿量与透气率有直接影响;织物紧度太大、太小都不利于织物的折皱回复,相同紧度下斜纹组织的抗皱性比平纹好;6种组织结构中2/2斜纹组织抗折皱性最好,2/2方平组织的顶破强力、抗起毛起球等级最高,2/2破斜纹透气、透湿性最好,2/2斜纹组织具有良好的保形性。
