The Comparison of Cotton Knitted Fabric Properties Made of Compact and Conventional Ring Yarns Before and After the Printing Process

Abstract

Ring spinning is still accepted as the most important method in short staple spinning, and in spite of the new spinning methods which came on the scene with the purpose to increase the production, ring spinning is still in the first category owing to its continuous development. Studies in recent years showed that spinning triangle in conventional ring spinning has a noticeable effect on yarn hairiness, yarn strength, yarn elasticity, processing performance and fly formation [1]. After this determination, studies were intensified on decreasing the spinning triangle [2]. As a result of these studies, a new spinning system was developed which was named compact spinning and which decreased the yarn hairiness to a great extent [3]. Literature SurveyIn compact spinning, a different yarn structure is produced. Most apparent features of these yarns are their high strength and elongation values and low hairiness [4][5][6]. When using compact yarns in knitting process, practical applications offered some advantages, such as decreases in abrasion, dust and fly, thus, decreas 1 ing cleaning costs, needle breakages and fabric faults [7].In this study, in the light of the existing information about compact spinning, possibilities of the system have been investigated in detail on the basis of yarn by using compact and conventional ring yarns in different fineAbstract Compact spinning is a new version of ring spinning and the most distinct features of these yarns are their high strength and elongation values and low hairiness. In this study, we attempted to find the differences between compact and conventional ring knitted fabrics. One hundred % cotton yarns, produced from the same cotton blend, were spun according to compact and conventional ring spinning principles in two different yarns counts and twist multipliers. Three different knitting structures, interlock, rib and single jersey, were produced from these yarns. The physical properties of these fabrics were investigated and compared with each other before and after the printing processes. When the results were studied, it was seen that hairiness of compact yarns was less and their strength and elongation percentages were higher. They showed less tendency to pilling and had higher bursting strength. No statistical differences were observed with regard to weight, abrasion resistance, color efficiency and rubbing fastness.

Factors Affecting the Functional- and Comfort-related Properties of Reactive Dyed Cotton Knits

“…The variation in the aforementioned performance and comfort properties when using different yarn counts as well as softening agents could be expected to depend upon: (i) knitted fabric structure, e.g., surface area, hairniness, interfiber and interyarn friction, length of the knitted loop, fabric thickness, compactness or looseness, etc. [1,3,4,13,14], and (ii) softener type, e.g., chemical nature, molecular structure and softener form, reactivity and affinity for the dyed substrates, mode of interaction, location, and extent of distribution onto and/or within the treated substrate along with its tendency and ability to form a waxy thin film/interfiber-interyarn bonds as well as to act as a lubricant [6,8,10].…”

A study on the relationship between irregularity and hairiness of spun yarns

“…Therefore, the yarn surface appearance is closely related to the yarn surface hairiness. [12][13][14][15] Another key factor influencing appearance is yarn unevenness which refers to the mass variation of yarn. It is well known that an uneven yarn usually possesses a large amount of thick and thin regions.…”

Hazard and Risk Analysis for Ring Spinning Yarn Production Process by Integrated Fta-Fmea Approach

“…Yarn quality also depends on the production conditions. In order to improve yarn quality in the literature, many number of studies have been conducted to optimize production conditions [9][10][11][12][13][14]. Küçük and Güner [2] analyzed the efficiency value of firms in the textile industry by using fuzzy logic approach and ranked criteria that have impact on efficiency value.…”
