Preparation of the polyester/cotton composite yarn with alternating segmented structure and interval color via a promising physical spinning approach

Herein, a novel kind of composite yarn with alternating segmented structure and interval color has been prepared based on a ring spinning approach. By adjusting the relative motion and blend ratio of the colored polyester filament and natural cotton staple fiber in yarn spinning process, a series of composite yarns were designed and prepared with various segmented structure and cyclical change of the distinct colors. The blend ratio was found to strongly influence on the segment frequency and yarn performance, achieving an improved mechanical property and yarn performance. A color systematic analysis indicated that the combination of alternating structural change induced interval color sense and gradient at the merged regions would lead to an enhanced stereoscopic visual effect of the composite yarns. Moreover, the composite yarns were confirmed to have an excellent weavability and able to endow different patterns and visual effects to the textiles. Thus, considering of the above advantages and multifunctionalities, this work should spur great possibilities for dyeing industry with the promising physical spinning method.

Sensorial Merchandising: Um Experimento no Varejo de Moda para Inclusão de Consumidores Cegos

Esse artigo propõe o conceito de sensorial merchandising a partir do entendimento da atmosfera de varejo como um esforço para gerar uma experiência de compra, com pessoas com deficiência visual. Os deficientes visuais no varejo de moda, devido a certas limitações, necessitam de algumas mudanças na atmosfera do setor. O objetivo, então, é compreender os anseios dos consumidores, e assim dar subsídios as empresas de varejo de moda para que promovam sua autonomia no ato da compra utilizando uma cartela de cores com aroma de fruta/fruto, Color Sense, como elemento do Sensorial Merchandising. A metodologia adotada foi um experimento de estudo de caso único realizado em ambiente controlado. Os resultados obtidos sugerem uma relação positiva do consumidor cego com a Color Sense, assim como os demais elementos do Sensorial Merchandising.

Konsentrasi Asam Sitrat terhadap Mutu Sari Buah Mangga Indramayu

Mango (Mangifera Indica L.) cengkir known as the mango from indramayu, so often referred to as the mango indramayu or dermayu. this study aims to know the fruit juice mango indramayu instant and know the concentration of citric acid to quality organoleptic sari mango indramayu instant. step of kerjaa of this study include the preparation of materials and equipment, weighing, cutting, blanching, destruction, filtering, the addition of citric acid and egg whites, drying, in a blender, the addition of sugar, packaging. this study was conducted in the laboratory faculty of agriculture University gorontalo and laboratory polyteknik gorontalo. research methods do is the design of randomized complete with three treatment (0,7%, 0,8%, 1%) and the three times Deuteronomy so that the number of observations is 3. the analysis of the concentration of citric acid include the analysis of water content, vitamin C., and test organoleptic. the results showed that citric acid as much as 1% make water content high ie 2,07 on treatment a3, citric acid in vitamin C. the 5,74 a1. and at the test organoleptic panelists terms of color, sense, the smell like treatment on a1 ie 0,7% citric acid.Keywords : citric acid, mango, vitamin C, organoleptik

Color Vision

This chapter addresses why animals have evolved different numbers, ranges, and placements of spectral channels in their color-vision systems. It also examines the factors, such as water transmission, visual task, phylogeny, and activity patterns, that drive the evolution of such diverse modes of seeing color. Even in the absence of any color sense, trees are still visible, as most of the information in natural scenes can be gained from achromatic cues alone. Color vision, however, gives an animal more information, allowing it to make quicker and more informed decisions. The chapter attempts to disentangle man's experience of color from that of other animals to provide an objective measure of what color vision is and how evolution has molded its variety of forms.
