“…On the other hand, the positive correlation observed between yarn linear density and weight in this current study is in agreement with what Saiman et al (2014) found. They explained that higher linear densities result due to higher fibre loading in the yarns; in effect influencing weight and strength of the fabrics.…”

This study compared three brands of fabrics used for the production of Ghanaian public basic school uniforms based on selected performance characteristics to determine their suitability for the end-use in terms of the properties assessed. The parameters evaluated with the use of experimental procedures included yarn count, weight, colourfastness and shrinkage. The data collected were analysed with the use of the Predictive Analytical Software for windows version 22. Means and standard deviations of the fabric performance characteristics evaluated were calculated. Analysis of Variance at 0.05 alpha level and Pearson Product Moment correlation were also employed. The findings showed significant differences among the investigated fabrics performance characteristics. All the fabrics met the standard specifications for uniform fabrics indicated in the Ghana Standards Authority's specification for uniform fabrics (GS 970, 2009) for the parameters colourfastness, weight and dimensional stability. However, just as these three parameters cannot be used to judge the overall suitability of the fabrics for the end-use. It is therefore recommended that further investigations are carried out on the fabrics to evaluate the other characteristics such as strength and absorbency which could help to establish the better suitability of the investigated fabrics for the end-use (uniforms).

“…Numerous researches have been done by utilising natural fibre in a form of fabric to produce woven composite (Table 1). Saiman et al [21] have fabricated a series of woven kenaf composite with different yarn linear densities and weave structures using a polyester (PE) matrix through a vacuum infusion technique and have found that both parameters have a significant influence on the tensile properties of the composite. Research that has been done by Azrin Hani et al [12] have demonstrated that woven kenaf and coir have a high potential to be used as reinforcing materials, and they also concluded that fibre type and reinforcement structure parameters affect the mechanical properties of the composites.…”

The effects of different fabric materials namely weave designs (plain and satin) and fabric counts (5 × 5 and 6 × 6) on the properties of laminated woven kenaf/carbon fibre reinforced epoxy hybrid composites were evaluated. The hybrid composites were fabricated from two types of fabric, i.e., woven kenaf that was made from a yarn of 500tex and carbon fibre, by using vacuum infusion technique and epoxy resin as matrix. The panels were tested for tensile, flexural, and impact strengths. The results have revealed that plain fabric is more suitable than satin fabric for obtaining high tensile and impact strengths. Using a fabric count of 5 × 5 has generated composites that are significantly higher in flexural modulus as compared to 6 × 6 which may be attributed to their structure and design. The scanned electron micrographs of the fractured surfaces of the composites demonstrated that plain woven fabric composites had better adhesion properties than satin woven fabric composites, as indicated by the presence of notably lower amount of fibre pull out.

“…It is important to study yarn structure essentially yarn types, linear density, sizes, mechanical properties and twist effect as they determine the structure of woven fabric. Many researchers have reported results incorporating yarn properties into composite properties (Chattopadhyay 2008;Gabrijelcic et al 2008;Hani et al 2013;Junior et al 2004;Liu & Hughes 2008;Saiman et al 2014). It has been concluded that several yarn factors affect the woven fabric characteristics for composite application and it is important to pay particular attention in the selection of appropriate yarn types.…”

Currently, there is a growing interest of using woven material in composite production for many applications such as structural applications, non-structural applications, household utilities, parts for automobile, aerospace components, flooring and ballistic laminate composites. The structure and properties of the woven fabric is very important as it dictate the woven composite properties. The properties of yarn like linear density, twist factor and strength can influence most of the woven fabric properties. Strength of woven fabric is one of the most important properties which make it superior in final composite applications. In this study, the effects of linear density i.e. 500, 1000, 1500 and 2000 tex on physical and mechanical properties of kenaf yarn were evaluated. The assessment on twist type, twist angle, yarn diameter, yarn structure, fibre density, moisture content, water absorption and mechanical properties were carried out on kenaf yarns. The yarn mechanical properties were tested on the tensile strength, Young's Modulus and elongation. It was found that, different linear density of yarn exhibited different behavior of yarn properties. Higher linear density yarn produced wider yarn diameter compared to lower linear density yarn, resulting to higher fibre and moisture content yarn. Yarn tensile strength has increased by 46% when linear density was changed from 500 to 2000 tex due to higher amount of individual fibres. However, for Young's Modulus, the values reduced as the yarn linear density increased due to several factors including number of fibres and moisture content of yarn.
