Investigation on the effect of cotton-tencel (50:50) siro yarn twist multipliers on fabric stiffness.

The properties of fabrics are mainly affected by constituent fiber properties and yarn structures. The yarn structures are primarily dependent on the spinning technique. The twist multiplier is a leading factor influencing yarn structure which directly correlates with fabric stiffness and mechanical properties due to structural behavior. In this study, siro spun yarn has been prepared using different twist multipliers (3.6, 4, 4.4, and 5.0) by blending cotton and tencel fiber at the spinning stage to investigate the effect of twist multipliers on fabric stiffness and the flexural rigidity of woven fabrics. The 1/1 plain, 2/2 twill, and 8-end satin fabrics have been woven using prepared yarns in warp and weft directions. The fabric stiffness has been measured using the ASTM D1388-2018 method. The results reveal that fabric stiffness increased with the increasing twist multiplier. Furthermore, a comparative study on different weave structures shows significant differences in stiffness. Overall, the experimental results present a close relationship between twist multiplier, spinning triangle, float length, fabric stiffness, and rigidity, and also show the optimum twist level for cotton-tencel siro yarn to attain maximum stiffness and strength.

Study on mechanical property of woven fabrics made from 50/50 cotton-tencel blended siro yarn.

The main objective of this study is to examine the tensile properties of a sustainable woven fabric made of cotton-tencel siro-spun yarn, which is widely used in the apparel industry. Tencel fibers incorporate several excellent sustainability features into their manufacturing process, such as recycling water and chemicals to reduce waste and extracting the trees to sustainably harvested forests. Similarly, cotton is durable, recyclable, and biodegradable, making it an excellent choice as an eco-friendly fabric throughout its product life. 3.8, 4.0, and 4.2 twist multiplier yarns were used in this experiment. The rotational multiplier is a factor that determines how many times the yarn is spun during the spinning process. This refers to yarn strength used in weaving or knitting, as well as the appearance of the finished fabric. All fabrics were made in plain, twill, and satin weaves with warp densities of 100, 95, and 90 ends/inch and weft densities of 60, 55, and 50 picks/inch, respectively. To determine the tensile strength of woven fabric made from 50/50 cotton - tencel siro yarn, elongation at maximum force and force at rupture tests were performed in the greige state as well as after desizing, scouring, and bleaching. The twist multiplier and woven structure were revealed to be largely responsible for the strength of woven fabrics in greige as well as after desizing, scouring, and bleaching. A comparison has made to investigate the rupture force and elongation of proposed technique with ring spun yarn fabrics. In reality, this work demonstrated comprehensive information about the woven fabric properties of 50/50 cotton - tencel siro yarn, which could be useful in understanding their mechanical behavior.

An approach to improve the pilling resistance properties of three thread polyester cotton blended fleece fabric.

Pilling is a common surface defect in fleece fabrics made of chief value cotton (CVC) and polyester cotton (PC). The term "Chief Value Cotton" refers to fabrics produced by mixing cotton and synthetic fiber such as polyester where cotton typically makes up more than half of the overall combination of polyester. Customers nowadays want polyester cotton blended fleece fabric with excellent pilling resistance, but it is difficult to improve pilling properties in polyester cotton blended fleece fabric. A variety of studies have been conducted to improve the pilling properties of single jersey CVC knit fabric. The primary goal of this study is to eliminate pilling in fleece fabrics made of three-thread polyester cotton blends. In this analysis, singeing with a heat setting was used to increase pilling resistance. According to this experimental study, the pilling resistance properties improve from grade 1 to grade 4, which is extraordinary. This method can be used to successfully solve the pilling problem in three thread polyester cotton blended fleece fabrics in the textile knitting industry.

Selection of suitable knitting parameters for 1 x 1 rib collar manufacturing in V-bed knitting machine.

The main components of a polo shirt are the body and collar. For different body measurements, different collar sizes are needed. It is very crucial to select the perfect collar size according to body size; otherwise, collar size will be larger or smaller than the required size. However, producing and maintaining perfect collar size concerning body size is very tough as the collar is tiny. If the finished collar size is larger or smaller than the appropriate size, the manufacturer is supposed attach the incorrectly measured collar to the body, placing the customer at risk of a vital quality argument. Otherwise, the manufacturer would have to remake the collar, wasting both time and money. Sometimes, the knitting industry has to deal with purchase order cancellations due to a lack of lead time for replication. To avoid the complexities described earlier, quantitative equations for collar production based on the number of ply, stitch duration, and needle count were established in this study. The precision of this exploration work is approximately 100 percent for matching exact collar size with body size. As a result, the evolved technique can be used in the textile knitting industry to ensure that accurate specifications are met the first time.
