Long Staple Processing and Textile Testing Volume 3, Issue 3, Fall 2003 Long Staple Processing and Textile Testing Dean R. Cobb Institute of Textile Technology ABSTRACT Several vendors in the long staple processing area and the textile testing unveiled some improvements to their existing offerings. The long staple improvements came in the form of better design, more productivity, more electronic controls, less maintenance requirements, versatility, and cross compatibility with automation of all types. Improvements from some testing vendors mainly concentrated on yielding more information from the same tests; like the sticky cotton measurement from Lintronics and Weavability from Uster.

Ben Ameur2 1Textile Engineering Laboratory, University of Monastir, Monastir, Tunisia 2Technical Center of Creation, Innovation, and Supervision in Carpet and Weaving, Tunis, Tunisia Abstract This experiment was aimed to identify wool quality of Tunisian sheep breeds. Fiber characteristics of different ages and various sheep breeds were studied. A total of 84 sheep were used in this study. Results show that the factor 'breed' had a highly significant effect on all controlled parameters accept scoured yield and fibre length. Breed was the most important factor. By conducting well-planned sorting, “Fine Queue of west” sheep breed can supply the wool needed for textile industries. The wool of other sheep breeds can be used in handmade carpets.

  • Genetic Variability Studies in Gossypium Barbadense L
    Electronic Journal of Plant Breeding, 1(4): 961-965 (July 2010) Research Article Genetic variability studies in Gossypium barbadense L. genotypes for seed cotton yield and its yield components K. P. M. Dhamayanathi , S. Manickam and K. Rathinavel Abstract A study was carried out during kharif 2006-07 with twenty five Gossypium barbadense L genotypes to obtain information on genetic variability, heritability and genetic advance for seed cotton yield and its yield attributes. Significant differences were observed for characters among genotypes. High genetic differences were recorded for nodes/plant, sympodia, bolls as well as fruiting points per plant, seed cotton yield, lint index indicating ample scope for genetic improvement of these characters through selection. Results also revealed high heritability coupled with high genetic advance for yield and most of the yield components as well as fibre quality traits. Sympodia/plant, fruiting point /plant, number of nodes/plant, number of bolls per plant, and lint index were positively correlated with seed cotton yield per plant and appeared to be interrelated with each other. It is suggested that these characters could be considered as selection criteria in improving the seed cotton yield of G. barbadense , L genotypes. Key words : Gossypium barbadense , genetic variability, heritability, genetic advance, lint index, selection criteria Introduction Seed cotton yield is a complex trait governed by Cotton is the most widely used vegetable fibre and several yield contributing characters such as plant also the most important raw material for the textile height, number of monopodia, number of industry, grown in tropical and subtropical regions sympodia, number of bolls, number of fruiting in more than 80 countries all over the world.

  • Determination of Optimum Twist Equation for the Long Staple Combed Cotton Ring-Spun Yarn
    fibers Article Determination of Optimum Twist Equation for the Long Staple Combed Cotton Ring-Spun Yarn Dunja Šajn Gorjanc 1,* and Neža Sukiˇc 2 1 Department of Textiles, Graphic Arts and Design, Faculty of Natural Sciences and Engineering, University of Ljubljana, Snežniška, SI-1000 Ljubljana, Slovenia 2 Predilnica Litija, Kidriˇceva,SI-1270 Litija, Slovenia; [email protected] * Correspondence: [email protected]; Tel.: +386-1-2003220 Received: 5 August 2020; Accepted: 17 September 2020; Published: 21 September 2020 Abstract: The aim of this research was to determine the optimum twist equation for ring-spun yarns. The yarn twist can be calculated by different equations. With the research, we tried to find the appropriate equation to determine the yarn twist, which is determined by the values of yarn strength and hairiness. In the research, yarns from long staple combed cotton rovings and of different fineness (10 tex, 11.8 tex, 20 tex and 29.4 tex) were analyzed. The yarn twist was calculated using the equations of Koechlin and Laetsch. The analyzed yarns were produced in the spinning mill on the laboratory ring spinning machine Spinntester. In the second part of the investigation, yarn strength and hairiness were analyzed as a function of yarn twist. The results showed that Laetsch’s equation is suitable for determining the twist for yarns with a fineness of 10 tex, 11.8 tex, 20 tex and 29.4 tex, since, in this case, the calculated number of yarn threads is higher and thus the strength and elongation at break are also higher.

  • CORESPUN VERSUS SPUN POLY Threads
    TECHNICAL BULLETIN CORESPUN VERSUS SPUN POLY Threads What are the major differences between A&E’s corespun brands like Perma Core® and D-Core® and Spun Polyester know in Asia as “pp” threads? What impact does using one versus the other have on the quality of your sewn products? CORESPUN Corespun threads, sometimes referred “pcore” or “polycore” or “cottoncore”, are made by wrapping a staple polyester or cotton wrapper around a continuous filament bundle of polyester fibers during spinning, and then plying these yarns into a sewing thread. The continuous filament polyester core makes up approximately 60% of the thread construction. This core contributes to: • Higher strength per size (higher tenacity) • Greater uniformity in size, strength and other physical characteristics • A higher initial modulus or resistance to stretching contributing to better loop formation and reduced seam puckering. • Better ply security – fewer unravel type thread breaks • Superior abrasion resistance & durability The wrapper of a corespun thread can be either staple polyester or staple cotton. The wrapper gives the thread a fibrous surface that contributes to: • A softer “hand” or feel than a 100% continuous filament threads • A matte finish stitch appearance similar to a spun thread construction • Superior frictional characteristics compared to a continuous filament threads • Poly wrapper contributing to: o Superior color fastness, chemical and abrasion resistance o Higher strength than cotton wrapped corespun threads o Superior “union dyeing” because of one-step dyeing process • Cotton wrapper contributing to: o Superior needle heat resistance o A “wash-down” stitch appearance TECHNICAL BULLETIN Core threads are recommended for the most demanding sewing applications from sewing fine blouses that are susceptible to seam puckering ..
