Composite coatings are exposed to many environmental conditions, which can significantly affect them. In this research, three different surface treatments were introduced to examine their effects on the adhesion between the composite coating and the substrate. These treatments were plasma cleaning, ultraviolet (UV) radiation, and sanding. A cross-cut test was conducted on the composite panels to assess the adhesion of paint to the substrate after all three treatments. Coating performance analyses were also carried out using a Fourier transform infrared spectrometer, contact angle, and optical microscopic images. The first set of panels was treated for 4, 8, and 12 minutes with oxygen plasma, and the surface wettability was assessed by contact angle measurement. The second set of panels was treated with UV radiation for 2, 4 and, 8 days, and the surface wettability was also assessed using the contact angle test. A few samples were treated with sandpaper. Two coats of paint, including a primer and a top coat, were used, and the panels were exposed to UV radiation and immersed in water. It was found that untreated panels showed a much higher contact angle of 86°, whereas panels treated with plasma exhibited a 33° water contact angle. In the case of UV radiation, the contact angle of untreated panels was found to be 106°, whereas the contact angle of panels treated with UV radiation was reduced to 47°. Panels treated with sandpaper showed a contact angle of 24°, whereas panels without sandpaper treatment showed a contact angle of 73°. The cross-cut test showed considerable flaking of the coating along the edges and squares of panels that were not treated, and very small flakes along the edges and parts of the grid square on panels that were treated, thus confirming the enhancement of adhesion by plasma, UV, and sanding treatments. vi TABLE OF CONTENTS Chapter Page 1.

All rights reserved; America’s Cotton Producers and Importers. INTRODUCTION The desire of adding color and design to textile materials is almost as old as mankind. Early civilizations used color and design to distinguish themselves and to set themselves apart from others. Textile printing is the most important and versatile of the techniques used to add design, color, and specialty to textile fabrics. It can be thought of as the coloring technique that combines art, engineering, and dyeing technology to produce textile product images that had previously only existed in the imagination of the textile designer. Textile printing can realistically be considered localized dyeing. In ancient times, man sought these designs and images mainly for clothing or apparel, but in today’s marketplace, textile printing is important for upholstery, domestics (sheets, towels, draperies), floor coverings, and numerous other uses. The exact origin of textile printing is difficult to determine. However, a number of early civilizations developed various techniques for imparting color and design to textile garments. Batik is a modern art form for developing unique dyed patterns on textile fabrics very similar to textile printing. Batik is characterized by unique patterns and color combinations as well as the appearance of fracture lines due to the cracking of the wax during the dyeing process. Batik is derived from the Japanese term, “Ambatik,” which means “dabbing,” “writing,” or “drawing.” In Egypt, records from 23-79 AD describe a hot wax technique similar to batik.

  • FDM Nylon 12
    FREQUENTLY ASKED QUESTIONS FDM Nylon 12 1. What is nylon? Nylons were the first engineering thermoplastics. They have been around for 85 years and are one of the most widely used materials for traditional thermoplastic manufacturing today. Nylons falls into the polyamide (PA) class of materials. This is a material class that includes both natural substances (silk and wool) and synthetic materials (thermoplastics). All nylon materials are polyamides, but all synthetic polyamides aren’t nylons. Since nylon is such a recognizable material name, on our literature and in conversations, we will use it as the preferred term. 2. What nylon material is Stratasys offering? FDM® Nylon 12™ (unfilled) is the first nylon material that can be 3D printed with fused deposition modeling (FDM) technology. It has been highly demanded by our customers and complements our current FDM materials portfolio.

  • 24. Principles of Wool Fabric Finishing
    24. Principles of Wool Fabric Finishing Mike Pailthorpe Learning objectives On completion of this topic you should be able to: • Outline the use of wool fabric finishing flow charts • Describe the various contaminants that may be present in greige state wool fabrics • Describe the finishing methods employed to remove contaminants from greige state wool fabrics • Describe the various forms of dimensional change that take place in wool fabrics • Outline the finishing methods employed to control the dimensions of wool fabrics • Describe the finishing processes employed to modify handle and appearance of wool fabrics Key terms and concepts Inspection, burling, mending, scouring, crabbing, carbonizing, milling, shrink proofing, bleaching, dyeing, hydroextraction, scutching, drying, conditioning, raising, shearing, singeing, pressing, decatizing, perching. Introduction to the topic The object of wool fabric finishing is to develop the desired properties in woollen and worsted fabrics that meet the specified end use requirements of consumers. Finishing is a sequence of processes that is carried out in a logical order. For example, finishing processes employing aqueous based treatments, also known as wet finishing, are grouped together, the aim being to minimise water consumption and to dry the fabric only once. The so-called dry finishing processes follow after drying. There are four main objectives to be achieved during the finishing of wool fabrics. • The removal, by scouring, of contaminants from the fabric. These contaminants may include lubricants and antistatic agents employed in yarn and fabric production, warp sizes and lubricants, machine oil stains, etc. In some cases the wool fabric may also contain vegetable matter (VM), in which case the process known as carbonising may be used to remove the VM • The development of the required handle, softness, fullness, drape, etc.

A finished knitted fabric of cotton or other natural or re- generated cellulosic material which is lustrous, flat and dense and lacks spirality and edge curling, is crease resistant and has in addition good dimensional stability uncharacteristic of mer- cerized fabrics. An apparatus for finishing knitted cotton or other natural or regenerated cellulosic fabric is described, and also a process for finishing such knitted fabric. This invention relates to knitted fabrics of cotton or other natural or regenerated cellulosic fibres, or blends thereof with other fibres. Our Canadian Patent No. 765735 is concerned with an ammonia treatment of such fabrics, and also - and more particularly - of woven fabrics of the same materials, to impart thereto varying degrees of elasticity (stretchiness) and/or crease resistance. The process involves swelling the fibres of the fabric by impregnating it with liquid ammonia and, after a time interval, evaporating the ammonia from the still swelled fibres. As a matter of fact, however, the processes of the aforementioned patent have only ever been used significantly in connection with the treatment of woven fabrics.

  • Guide to Improved Shrinkage Performance of Cotton Fabrics
    TECHNICAL BULLETIN 6399 Weston Parkway, Cary, North Carolina, 27513 • Telephone (919) 678-2220 ISP 1009 A GUIDE TO IMPROVED SHRINKAGE PERFORMANCE OF COTTON FABRICS This report is sponsored by the Importer Support Program and written to address the technical needs of product sourcers. © 2004 Cotton Incorporated. All rights reserved; America’s Cotton Producers and Importers. INTRODUCTION Product specifications of textile and apparel products have always had a profound effect on the thinking and planning of managers in all areas of textile and apparel production. In today’s competitive markets where quality is expected at a low price, apparel companies are demanding low shrinkage from their suppliers to meet the needs of the consumer. In addition to low values, the shrinkage from garment to garment for the same style must be consistent. Traditionally, apparel manufacturers have set rigid specifications for their suppliers that in many cases allow little room for error in processing. In fact, some shrinkage specifications for apparel products may not be attainable at all by the suppliers of that product. In addition, many testing methods have been devised to measure shrinkage. Acceptance, rejection, and discount penalties are dependant on this gathered data. Further, in depth analysis of this data can allow for a better understanding of the causes of inconsistent or high shrinkage. A better understanding can then impact production techniques to make the shrinkage phenomena manageable. Indeed, more realistic specifications for a finished product can then be set for a fabric or garment based on the knowledge learned. This knowledge can also impact other product specifications such as weight and width as well as the determination of garment pattern layouts.

  • Fleece Sewing.Doc
    CT-MMB.159 Selection & Sewing Tips for Fleece Fabric One of the hottest items to hit the fashion scene in recent seasons has been fleece. What began as a trademarked fabric by Malden Mills in 1979, (Polarfleece®), the word polarfleece has become a household term among sewers. In today=s world, polarfleece fabric is marketed under a number of different trade names including Polarfleece®, Polartec®, Tundra FleeceJ, YukonJ ECO Fleece, and Arctic FleeceJ. Some of these fabrics are actually made all or in part from recycled plastic soda bottles. Regardless of their origins, fleece fabrics are characterized by a deep pile texture, made into a knit fabric structure. Polarfleece may be further defined and described as Aa type of high quality, double-sided, napped polyester fleece.@ Fabric Characteristics There are a number of fleece and fleece-like fabrics on the market. Since 1979, a great deal of research and development has taken place to provide a variety of fleece types and weights. All fleece fabrics have some common characteristics. However, various types may emphasize or focus on certain ones and introduce others. Common properties: ! provides warmth will being extremely lightweight ! has breath ability, allowing body perspiration to escape (wick) to the outside to be evaporated ! maintains insulative/warmth properties even when wet ! completely washable ! machine dryable on low heat; no ironing. Other qualities that are introduced in some brands include antimicrobial finish, non-pilling, fleece that is laminated with a waterproof and windproof breathable lining, thin and thick pile, and a wide variety of surface textures. Some companies actually feature a fashion-apparel fabric line as well as an outdoor-enthusiast line geared toward serious climate considerations.
