Mazharul; Islam, Md. Nazmul Contemporary garment enterprises must exhibit remarkable adaptability to create diverse styles and types of clothing in response to market demands for their survival. Enhanced excellence across all dimensions justifies optimum pricing. In competitive marketplace, cost calculation of garment not only optimum for net profit generation but also necessary to avoid order rejection. During the initial stages of order acquisition, fabric consumption estimates must be established using mathematical approximations before actual marker creation. Among the two commonly employed mathematical methods for fabric consumption, the alignment of specific formulas with particular garment types has not been thoroughly analyzed. The aim of this study is to identify the most accurate method of fabric consumption for various garment categories. For this purpose, six distinct garments have been selected for experimentation: two woven shirts (short and long sleeves) and four knit Tshirts (including two set-in sleeve variations with long and short sleeves, and two raglan sleeve variations with long and short sleeves). Pattern making and grading were executed using specification sheet measurements, followed by marker creation utilizing Boke CAD software. Subsequently, fabric consumption for all six garments has been compared using 3 fabric consumption methods: one marker planning method and two mathematical methods. Although the marker planning method is well-established as the most accurate means of fabric consumption determination, its usage requires pattern and marker preparation prior to production. This limitation necessitates the use of mathematical formulas during preliminary stages for cost calculations and order processing. Comparative analysis highlights that neither mathematical formula is universally suitable for all garment types, suggesting that specific formulas should be applied to distinct garments. As such, this guideline serves as a valuable industry resource, preventing unnecessary fabric wastage caused by misusing mathematical formulas and thereby contributing to sustainability efforts.

Nasir; Hawlader, Md. Rashel; Islam, Md. Nazmul; Hossain, Md. Mosharof; Bristy, Sraboni Ahmed; Faysal, G. M. It is a great challenge for textile spinners to ensure the quality of ring-spun blended yarn (CVC) with smooth production. 30 Ne blended yarn (Cotton and polyester at the ratio of 60/40) was produced during this research work because it is a more frequently used count for blended yarn. Different parts of the Ring Frame influence the quality of yarn. Among them, the role of the spacer is significant as it controls the movement of fiber during drafting at Ring Frame. This study introduced three spacers of different sizes (2.3 mm, 3.1 mm and 5.1 mm) by keeping the same raw materials and setting parameters for mentioned yarn count. Spacer size 3.1 mm showed the outstanding properties of yarn in terms of unevenness, imperfections and hairiness compared to the other spacer sizes. There is no significant changes in the blend ratio for changing the spacer. This work has the potential to select the appropriate spacer size (mm) that will help textile technologists during decision-making.

Rashel; Hossain, Md. Mosharof; Islam, Md. Nazmul; Murad, Sanaullah; Faysal, G. M. The core-spun yarn has gained much concern and popularity all over the world for having elastic and comfort properties. Draft ratio of the core, the number of cores and the type of sheath material are the prime parameters of producing core-spun yarn. These parameters influence the physical and mechanical properties of the yarn. In this study, the effect of the number of core-spun yarn cores was investigated on the yarn's physical and mechanical properties. Two types of core-spun yarn were produced: single core-spun yarn and dual core-spun yarn. Cotton fibres were used as a sheath, spandex monofilament and polyester multi-filament were used in the core. It was revealed that dual core-spun exhibits lower unevenness, imperfection and hairiness value than single core-spun yarn. In addition, bundle strength of yarn was found higher in dual core-spun yarn.

Sanaullah Traditionally deterministic algorithm for quicksort is used which gives O (n log n) running time for an average case and O (n2) for the worst case, where n is the number of elements to be sorted. If a randomized approach is used the worst-case running time is reduced to O (n log n). The median of three approaches for choosing pivot and multi-pivot approach like dual pivot also improves the running time. In this paper, we analyze the effectiveness of various pivot positioning methods. To achieve this, we take randomized generated and shorted array of different sizes which provide us with enough data to conclude.
