Effect on Textile Behavior of Fleece Types and Dehairing Process on the Linear Density and Regularity of Yarn from Argentine Llama Fibre

 The textile industry usually ignores the existence of types of fleece in South American Camelids, however its biological base has been widely demonstrated [1]. On the other hand, it is suggested the utility of classifying the lots by types of fleeces, before dehairing, foreseeing a differential textile behavior of the fiber [2,3].

 Comparing the textile behavior of various Australian wool, cashmere and alpaca, it has been shown that the regularity and general quality of the yarn depend to a large extent on the type of crude fiber of which it is composed [4].

 In a very extensive work on fabric softness, all judges perceive alpaca fiber (26μm) to be significantly softer than wool of the same diameter, also the softness of alpaca fibre could not be distinguished from the softness to the fine Merino wool (17μm). This first evaluation was about wool and alpaca tops. But, on the other hand, most of the same judges found the surface of the alpaca fabrics more prickly than wool yarn of similar fineness, because the alpaca fabrics was more hairiness than the wool fabrics of similar yarn fiber diameter, and this surface effect of hairiness interfere on softness and prickling perception of consumers [4]. It is necessary to emphasize that the alpaca fibre was not dehaired in this work.

Saturated Fatty Acids Derivatives as Assistants Materials for Textile Processes

Image
  Abstract Many auxiliaries have been used in textile industries in dry or wet processes. One of the important based materials is fatty acids and its derivatives. The present work aims at preparing some textile auxiliaries based on saturated fatty acids. Six different materials were used to react with each fatty acid. Produced materials have been characterised using FT-IR, HLB and cloud point. Based on the HLB values, produced materials have been used as softeners or as O/W emulsifiers (printing paste). Treated fabrics with softeners show a very good physical and mechanical properties and printed fabrics with prepared pastes shows a good printing paste with good prints characteristics (colour strength and colour fastness).

Modern Fibers: A Human- Centered Technology

Image
Textile Science and Fashion Technology Clothing represents one of the most ancient forms of human expression and is a tool that an individual use to express his/her culture and social status in society. Since the dawn of civilization, humans have used fabrics to provide basic warmth and show aesthetics. People gradually added more patterns and styles, creating clothing out of different materials. Today, the U.S. fashion and apparel industry are a $12 billion business, with the average American family spending $1,700 on clothes annually (BLS Data 2018) [1]. The fiber sector of the clothing and textile industry has undergone substantial change in recent years, and the modern fibers have opened a whole new frontier for clothing products. Modern fibers, also known as smart fibers, are becoming a human-centered technology. The smart fabrics will have the capability to see, hear, and sense their surroundings and to respond to the external stimulus through an active control mechanis...

The Rain Maker

Image
Opinion On the bottom floor of the Besse Library and across the Media Center is a room that either most people probably don’t pay attention to or always wonder what it contains. The room holds thousands of stories from all over the country, dating from over a century ago to the present day. These stories are not limited to paper and a bound cover but by thread and fabric. They all help create the Historic Costume Study Collection. Upon entering the cold room, you might feel overwhelmed. On the wall to the left are shelves that contain purses, hats, and muffs; on the right, there are shoes, gloves, and jewelry in cabinets and in repurposed library catalog card holders. Of course, you cannot overlook the mountain of garment boxes reaching up to the ceiling. The back wall has the fur and extensive wedding gown sections. Clothing racks are placed in messy rows that make maneuvering around difficult. The Historic Costume Study Collection has all you could ever need and want from fashion. Th...
