Specialty animal fibers are commercially valuable since they significantly enhance the comfort properties of apparel products. As they help to create niche products, use of special animal fibers has increased significantly. There are many types of specialty fibers, such as cashmere, mohair, alpaca, and angora rabbit fibers, that are natural, ecological, and sustainable. Each of them has distinguishing properties and increases the added value of garments. In this work, five different specialty animal fibers and wool were sourced from four different countries. Yarns were spun using two different spinning systems. In the first method, to spin the yarns in a short staple spinning system, animal fibers were blended with viscose fibers. In the second method, to produce fabrics from 100% animal fibers, core yarn spinning system was used. Later, the yarns were knitted in a single jersey structure. After the production of all fabrics, handle properties such as surface friction, stiffness, and prickliness were tested by using both subjective and objective measurement techniques. To measure inherent fabric prickle, a new objective measurement technique was developed. Subjective and objective evaluation results highly correlate and it is pointed out that the new technique could be an alternative method to test fabric prickliness. Fabrics produced from silk, angora, and cashmere fibers are found to have the smoothest, softest, and least prickly surfaces among the other researched fibers.
Excessive sound causes growing public well-being problems and significant environmental contamination in our daily life. Generally, most of the noise problems are difficult to be treated at source, and the reduction of noise emission is usually achieved through the use of noise isolation processes. In recent times, nonwovens as one of the most common textile products have become valuable sound absorption materials. These materials are used as sound absorbers, sound diffusers, noise barriers, and sound reflectors. For sustainable development of the textile industry, solutions for both decreasing waste and reducing noise have been searched for years. Due to the good sound absorbing properties, recycled materials are becoming an attractive option to traditional materials for practical purposes. In this study, the measurement methods of acoustic characteristics of textile materials are explained, and the sound absorption features of nonwoven fabrics made from both pure and recycled polyester and polypropylene fibers are compared.
Softeners are of great importance in textile processing. The aim of this treatment is to achieve a soft handle to facilitate
the processability and improve wettability. In this study, it was aimed to investigate the effect and washing durability of
various softeners on handle properties of cotton and bamboo knitted fabrics. Six types of softeners were applied to the
fabrics. Moreover, the washing durability of the softeners after 5, 10 and 20 washing cycles were tested. Handle
characteristics such as drapeability, kinetic friction coefficient and circular bending rigidity were measured. The results
were statistically evaluated. It was determined that softening treatment does not have a successful performance in bamboo
fabrics as it has in cotton fabrics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
