Meeting the Customer expectations on Yarn Quality is the topmost priority of the profitable spinning mills.WINSYS SMC explains the same alongwith Customer satisfaction measures.
Knowing the basics of raw material, yarn production process and the other factors influencing quality will put the sourcing manager at the same eye level as a spinner /supplier when negotiating quality issues.
As a consequence this puts the sourcing manager in the position to pay the right price for the corresponding quality level.
This kind of know-how supports a retailer enormously in his efforts to establish a reliable supply chain which is based on mutual understanding.

Spinning is the first steps of textile product processing. The process of making yarns from the textile fiber is called spinning. There are various types of spinning techniques for producing various types of yarn.
Filament-core yarns are produced to take advantage of both filament and staple fibre properties. They offer good strength and uniformity without sacrificing the staple fibre yarn-like surface characteristics. Core-spun yarns containing spandex provide fabric designers with broad possibilities, because such stretchable yarns can be constructed with a wide range of properties using virtually any type of hard fibres as the cover yarn. However, a disadvantage of the core yarns is that the staple fibre sheath may slip along the filament when being pulled to pass over or when being rubbed by machine parts during further mechanical processes. But it is very easy to produce core-spun yarn containing spandex in a conventional ring frame after doing some modification of the machine.
Warp knitting is a family of knitting methods in which the yarn zigzags along the length of the fabric, i.e., following adjacent columns ("wales") of knitting, rather than a single row ("course"). For comparison, knitting across the width of the fabric is called weft knitting.Warp knitting machines--needles are mounted collectively and rigidly in a horizontal metal bar (the needle bar that runs the full knitting width of the machine).
The yarn realization is the most important factor to assess the technical performance and profitability of spinning mills. Yarn realization means conversion of raw material in percentage terms into finished yarn. This articles described What are the key factors affecting yarn realization and how to manage it.
Hairiness is characterized by the quantity of freely moving fibre ends or fibre loops projecting from a yarn or textile fabric (woven, knitted or non woven fabrics).
In term of measurement Hairiness corresponds to the total length of the protruding fibres in unit length of one centimeter.

Textile fabric may be define as an assembly of fiber, yarn or combination of these. There are several ways to manufacture a fabric.To produce woven fabric yarn preparation is essential.Good preparation means good weaving,Good weaving =Quality fabric.
Cotton is a natural fibre available easily and abundant quantity. It is a most suitable fibre for textile spinning & clothing due to it’s good spinnability & human friendly characteristics. As cotton is a natural fibre hence it’s properties also affected with several other factors which create variation in fibre properties, these variations also affect spinning processes & it’s products Quality in multi dimensions. Each fibre characteristic impact individually and collectively on spinning process or at ultimate product quality. Revolutionary changes observed in last two decade in the field of spinning machineries where processing speeds greatly increased to enhance production rate. Not only production rate of spinning machines increased but speeds of it’s downstream processes also increased simultaneously which requires better quality of yarn for smooth process and without any interruption to get the maximum efficiency. Hence now it is most important to co-relate fibre properties with respect to it’s consumer process competency. In this article we will discuss the different cotton properties and it’s impact on spinning process and product quality in present prospective and will try to minimize the impact of poor fibre properties on process or product Quality through better Mixing plan selection.

Captronic séminaire électronique imprimée - 20/09/2017 - Présentation de VFP Ink Technology- En partenariat avec l’AFELIM (Association Française de l'Electronique Imprimée) et le soutien du Pôle Numérique de la CCI Bordeaux Gironde, Cap’tronic a organisé le mercredi 20 septembre dans les locaux de l’IMS à Talence, une rencontre autour de l' "électronique imprimée" afin de faire un tour d’horizon de la chaîne de valeur d'une filière dont le marché mondial est estimé à 330 milliards de dollars en 2027.
Quality may define as the level of acceptance of goods or services. It is a relative term. It completely depends on customer satisfaction. Actually product quality is based on product attribute. In textile and apparel industry, quality is calculated in terms of quality and standard of fibres, yarns, fabric construction, colour fastness, designs and the final finished garments.
Cost of woven fabric is the main concern of a garment merchandiser.Costing is a very complex procedure, with set patterns and guidelines followed by the industry, and it is difficult to find out costs for every process as there are some inbuilt costs while costing. Woven fabrics are used worldwide for many applications like apparel, home
furnishing, and accessories, industrial and medical textiles. It is estimated that the global production of woven fabrics will grow 35 million tones by 2010 and most
of this growth will be in Asia. It is also estimated that Asia will emerge as the biggest market for sourcing of fabrics for the garment and apparel industry. Costing of woven fabrics for garment manufacturers is one of the most important aspects of garment production. About 65 - 70% cost of the garment is the cost of the fabric and hence, it is very crucial to get the right cost of the fabric from fabric
manufacturers and suppliers.
Yarn printing is also known as “Space Dyeing”. Although the printing of yarns for true patterned effects proved very difficult tom control, the random space-dyed effects that can be more readily attained by a variety of yarn-printing methods have continued to be popular. The patent literature abounds with systems for producing colored flecked effects on yarns but the two most successful methods entail either warp printing or color application to a tubular knitted ‘sock’. The essential process sequence begins with dye liquor application, followed by steam fixation, washing-off and drying .

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
