“…The high modulus of weft, which contains polyester and spandex, indicates the high dimensional stability and shape-retention property of the fabric. The high flexural rigidity of cotton blended polyester-spandex core-spun yarn might have caused bulkier yarn [ 44 ]. So, higher flexural rigidity in the weft direction would give better fullness to the denim fabric.…”

This study aimed to investigate the effect of extensibility on cotton blended polyester-spandex core-spun yarn in the weft direction of 3/1 right-handed Z-twill denim. For the preparation of samples, 100% ring spun cotton yarn of 42 tex (14 s /1 Ne) was used as warp, and 70:30, 30:70, 60:40, and 40:60 cotton-polyester core-spun yarn of 30 tex (20 s /1) was used in the weft direction. Four categories of denim fabric were fabricated by using the air-jet weaving machine. Spandex yarn was used as a core material of weft with a percentage of 2%, 2.5%, 1.9%, and 1.8% respectively. Different physio-mechanical characteristics namely tensile and tearing strength, GSM, growth and recovery percentage, initial modulus, bending length, drape co-efficiency, abrasion resistance, flexural rigidity were evaluated to justify the quality of fabricated pieces of denim. Water wicking and breathability were taken into consideration when determining comfort. Higher cotton containing specimens exhibited lower tensile and tearing strength. Additionally, the produced denim fabrics showed balanced drapability and good breathability.

“…Coir is a coarse fibre in comparison with commonly used commercial textile fibres such as cotton and wool. The mean diameter of coir is around 280-320 µm [5] as against 10-15 µm for cotton fibre and 15-40 µm for wool fibre [6]. The coefficient of variation of coir fibre diameter is high at 50% [5].…”

Coir fibre is a non-conventional fibre extracted from the husk of coconut fruit and is abundantly available in tropical countries. Coir yarn is produced in the decentralised cottage industry. Increase in the demand for the coir fibre yarns for value-added applications has forced the coir yarn manufacturers to improve the existing coir spinning machine in different ways. In this study, the working principle of the existing coir spinning machine has been studied from the perspective of further improvements in production rate, yarn quality and spinning performance. Modifications have been made in the existing coir spinning machine in fibre feeding, opening and cleaning. There is improvement in the production rate of up to 20% with significant improvements in the yarn quality and spinning performance.

“…As people's awareness of environmental protection increases, synthetic fibers with a negative impact on the ecological environment are phased out. In development models prioritizing a green environment, people are looking for alternatives to synthetic fibers and are looking to natural fibers as options [1]. Natural fibers are attracting attention because of their environmental friendliness and renewable nature, as well as their low cost and good mechanical properties, accounting for their wide application [2].…”

As a type of natural fiber with excellent elongation, coir fiber has been applied in a wide range of fields. To ensure superb performance, coir fiber is usually treated with alkali before being applied. Previous studies paid little attention to the multiple alkali treatment of coir fiber; however, this study focuses on its influence on the mechanical properties of coir fiber and conducts multi-objective optimization and analysis of the tensile strength, elastic modulus and elongation of coir fiber. Our objective is the comprehensive enhancement of the mechanical properties of coir fiber. In this study, the experimental design is based on the Box-Behnken design method, and three treatment parameters were selected for the study, namely NaOH concentration, treatment time and treatment temperature. Analysis of variance (ANOVA) was adopted to analyze the experimental data, and response surface methodology (RSM) was used to investigate how the treatment factors interact with each other and affect the responses values. To improve the tensile strength, elastic modulus and elongation of coir fiber simultaneously, the experimental parameters were optimized. The results showed that the optimal values of NaOH concentration, treatment time and treatment temperature were 4.12%, 15.08 h and 34.21 °C, respectively. Under these conditions, the tensile strength of coir fiber was 97.14 MPa, the elastic modulus was 2.98 GPa and the elongation was 29.35%, which were 38.28%, 39.91% and 25.59% higher than that of untreated coir fiber, respectively. Furthermore, scanning electron microscopy (SEM), thermogravimetric analysis (TGA-DTG), Fourier-transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) were used to analyze the changes in surface, weight loss, composition and crystallinity of coir fiber treated with alkali under optimum conditions compared with untreated coir fiber to obtain a deeper insight into the influential mechanisms of alkali treatment.
