Make And Break Details: The Architecture Of Design-Build Education, Claire Nicholas, Arlene Oak
Make And Break Details: The Architecture Of Design-Build Education, Claire Nicholas, Arlene Oak
Department of Textiles, Merchandising, and Fashion Design: Faculty Publications
In the imagination of prominent architects and architectural theorists, the detail figures as both a promising and perilous element of built form. This paper explores the tension of the “make or break” qualities of the architectural detail(s) in the learning and doing of design, through an ethnomethodologically informed ethnography of North American design-build architecture education. The discussion parses three episodes which highlight the generative qualities of the detail, in terms of its pedagogical value for architecture, and as a heuristic for the study of design practice. As both the material process of joining disparate elements, and a locus for complex …
Non-Traditional Lightweight Polypropylene Composites Reinforced With Milkweed Floss, Narendra Reddy, Yiqi Yang
Non-Traditional Lightweight Polypropylene Composites Reinforced With Milkweed Floss, Narendra Reddy, Yiqi Yang
Department of Textiles, Merchandising, and Fashion Design: Faculty Publications
Lightweight composites are preferred for automotive applications due to the weight restrictions and also due to the presence of inherent voids that can enhance the sound absorption of these composites. The density of the reinforcing materials plays a crucial role in such lightweight composites. Milkweed is a unique natural cellulose fiber that has a completely hollow center and low density (0.9 g cm−3) unlike any other natural cellulose fiber. The low density of milkweed fibers will allow the incorporation of higher amounts of fiber per unit weight of a composite, which is expected to lead to lightweight composites with better …

Developing Water Stable Gliadin Films Without Using Crosslinking Agents, Narendra Reddy, Yiqi Yang
Department of Textiles, Merchandising, and Fashion Design: Faculty Publications
Abstract For the first time, gliadin films with excellent strength and water stability have been developed without using any crosslinking agents. So far, it has not been possible to obtain water stable gliadin films even after crosslinking. In this research, a novel method of using aqueous urea and ethanol has been developed to obtain highly water stable gliadin films without using crosslinking chemicals. The effects of concentrations of gliadin, urea and ethanol on the strength of the films and the stability of the films in water at high temperatures and various pH conditions has been studied. Gliadin films developed in …

Structure And Properties Of Cocoons And Silk Fibers Produced By Hyalophora Cecropia, Narendra Reddy, Yiqi Yang
Department of Textiles, Merchandising, and Fashion Design: Faculty Publications
This paper shows that silk fibers produced by cecropia (Hyalophora cecropia) have similar tensile properties but different amino acid composition than that of mulberry (Bombyx mori) silk. The cecropia fibers are also much finer and have better strength and modulus than tasar silk, the most common non-mulberry silk. Cecropia is one of the largest silk producing moths and has similar lifecycle to that of mulberry silk but is easier to grow and produces larger cocoons than mulberry silk. In this study, we have characterized the composition, morphology, physical and tensile properties, and thermal behavior of the …

Department of Textiles, Merchandising, and Fashion Design: Faculty Publications
The purpose of the research was to longitudinally investigate rural consumers’ online shopping for food and fiber products as a function of satisfaction with local retailing and outshopping. Innovation diffusion theory was used to guide the research. Eight hundred seventy-nine rural consumers from 11 states completed surveys twice (in 2000 and 2003). Data were analyzed using structural equation modeling and analyses of variance. Dissatisfaction with local retailing in 2000 was a powerful driver of outshopping, beliefs about online shopping, and online shopping (both in 2000 and in 2003). Outshopping was positively related to online shopping at both points in time, …
Citric Acid Cross-Linking Of Starch Films, Narendra Reddy, Yiqi Yang
Citric Acid Cross-Linking Of Starch Films, Narendra Reddy, Yiqi Yang
Department of Textiles, Merchandising, and Fashion Design: Faculty Publications
This paper shows that citric acid can cross-link starch and improve the tensile strength, thermal stability and decrease the dissolution of starch films in water and formic acid. The poor mechanical properties and water stability of starch have restricted its industrial applications. Although cross-linking is a common approach to improve the properties of starch products, current starch cross-linking methods are either expensive, toxic or do not impart the desired properties to the cross-linked materials. In this research, the possibility of cross-linking starch films using citric acid to improve their strength and stability was examined. Citric acid cross-linked starch films show …

Self-Crosslinked Gliadin Fibers With High Strength And Water Stability For Potential Medical Applications, Narendra Reddy, Yiqi Yang
Department of Textiles, Merchandising, and Fashion Design: Faculty Publications
For the first time, protein fibers with excellent mechanical properties and water stability have been produced from gliadin for potential use in tissue culture and other medical applications. Biomaterials developed from plant proteins such as zein and soyproteins are preferred for several medical applications over synthetic polymers such as polylactic acid. However, the plant protein based biomaterials developed so far have poor mechanical properties and hydrolytic stability even after crosslinking. This study aims to develop biomaterials from gliadin with excellent mechanical properties and water stability without using any crosslinking agents. A novel gliadin fiber production method was used to self …

Lignocellulosic agricultural byproducts are a copious and cheap source for cellulose fibers. Agro-based biofibers have the composition, properties and structure that make them suitable for uses such as composite, textile, pulp and paper manufacture. In addition, biofibers can also be used to produce fuel, chemicals, enzymes and food. Byproducts produced from the cultivation of corn, wheat, rice, sorghum, barley, sugarcane, pineapple, banana and coconut are the major sources of agro-based biofibers. This review analyses the production processes, structure, properties and suitability of these biofibers for various industrial applications.
The Ultraviolet Protection Factor Of Naturally-Pigmented Cotton, Patricia Cox Crews, Gwendolyn Hustvedt
The Ultraviolet Protection Factor Of Naturally-Pigmented Cotton, Patricia Cox Crews, Gwendolyn Hustvedt
Department of Textiles, Merchandising, and Fashion Design: Faculty Publications
Textile Technology: The sun-blocking properties of a textile are enhanced when a dye, pigment, delustrant, or ultraviolet absorber finish is present that absorbs ultraviolet radiation and blocks its transmission through a fabric to the skin. For this reason, dyed fabrics provide better sun protection than bleached fabrics. Since naturally-colored cottons contain pigments that produce shades ranging from light green to tan and brown, it seemed reasonable to postulate that they would provide better sun protection than conventional bleached cotton, and that natural pigments might prove more durable to laundering and light exposure than dyes, but there is no published research …

Care Of Quilts-Cleaning , Shirley Niemeyer, Patricia Cox Crews
Care Of Quilts-Cleaning , Shirley Niemeyer, Patricia Cox Crews
Department of Textiles, Merchandising, and Fashion Design: Faculty Publications
Quilts need special care in cleaning, but even professionals don't always agree on the best methods for cleaning quilts or even whether it should be done. No two quilts are alike. Methods suited for cleaning one quilt may not be best for another. The fiber content, dyes, and construction make each one unique. Sometimes it may be advisable to clean a quilt. Usually it is best to leave it as is.
Deciding whether to clean a quilt involves careful thought. What is the fiber content? How is the quilt constructed? Can it withstand movement or agitation? Will the colors bleed …

UV absorbers and antioxidants topically applied to upholstery fabrics to reduce fading, separately and in conjunction with soil repellent finish formulations containing UV absorbers, were evaluated in this study. Over fifty upholstery fabrics were initially evaluated and fourteen were selected for further study. The fabrics were then topically treated with commercially available soil repellent finishes (a fluorocarbon and a silicone finish) containing UV absorbers or immersion-treated with one of thirteen UV absorbers or antioxidants. Following light exposure, color changes were evaluated visually and instrumentally. The results showed that neither the fluorocarbon nor silicone-based soil repellent finishes containing UV absorbers significantly …
A Comparison Of Selected Uv Filtering Materials For The Reduction Of Fading, Patricia Cox Crews
A Comparison Of Selected Uv Filtering Materials For The Reduction Of Fading, Patricia Cox Crews
Department of Textiles, Merchandising, and Fashion Design: Faculty Publications
The effectiveness of a UV filtering material of flexible polyester film containing a silver reflective coating was compared to the widely used UV absorbing filters that are almost colorless or have a strong yellow tint. The silver-coated polyester filters caused almost no distortion of color rendition when used as a filter for fluorescent lamps and provided greater protection of artifacts than did the almost colorless filters. The use of UV filters of polyester film with a reflective silver coating is recommended when filters with a strong yellow tint distort color to an objectionable degree and yet greater protection of artifacts …

Ultraviolet Absorbers: A Treatment To Reduce Fading And Degradation Of Textiles, Patricia Cox Crews, Barbara M. Reagan
Department of Textiles, Merchandising, and Fashion Design: Faculty Publications
Fiber artists, as well as museum personnel, have attempted to reduce fading and/or deterioration in textiles by 1) using lower levels of lighting, 2) using incandescent lights instead of fluorescent lights, and 3) using ultraviolet filters on fluorescent lights. However, in many public buildings and in some daylighted museum galleries, textiles may be displayed without protection from light by any of the above measures. Therefore, many contemporary textiles are subjected to unusually high levels of lighting because most North American buildings are well lighted by fluorescent lamps and/or daylight through large expanses of window glass that emit or transmit sizable …
