Yarn tension during manufacturing has a large influence on the processing efficiency, yarn properties, and hence on fabric characteristics. In this work the dynamic tension two-for-one twister was investigated and the effect of various parameters the dynamic were studied. A test set-up unit was built to simulate the Two-for-one twister, so the effect of spindle speed, winding velocity feed pack...
In order to determine the relationship between fiber properties of yarn quality in article, experiments were conducted using a passive method mathematical planning and regression equation was obtained for each optimal parameter. Based on experiments, it found that decrease micronaire, an increase tensile strength, length uniformity, leads specific strength yarn, coefficient variation number bre...
INTRODUCTION Stasilon(R) is a novel hemostatic woven textile composed of allergen-free fibers of continuous filament fiberglass and bamboo yarn. The development of this product resulted from controlled in vitro thrombogenic analysis of an array of potentially hemostatic textile materials and it has been cleared for both external and internal use by the United States Food and Drug Administration...
Fiber-reinforced composite materials have many advantages in various engineering applications when compared to traditional such as glass, metals, ceramics and unreinforced plastics. Recently, textile-reinforced composites are increasingly used industries including aerospace, construction automotive. This study aims investigate the geometric characteristics of three-dimensional (3D) woven prefor...
چکیده : یکی از بخشهای اصلی در صنعت نساجی مقدمات بافندگی است. جایی که اهداف زیادی را بمنظور بهتر شدن شرایط بافندگی دنبال می کند. یکی از مراحل مقدمات بافندگی، بوبین پیچی می باشد که نخ روی ماسوره را روی بوبین منتقل می کند. بوبین پیچی نامشخص در کنار محاسن زیاد و کاربرد گسترده خود در صنعت، در حین تولید باعث ایجاد عیوبی روی بسته می گردد. بطوری که در قطرهایی از بوبین در حین پیچش نخ، حالت نواری شدن رخ...
In industrial textile pre-treatment and finishing processes, mass transfer and mass transport are often rate-limiting. As a result, these processes require a relatively long residence time, large amounts of water and chemicals, and are also energy-consuming. In most of these processes, diffusion and convection in the inter-yarn and intra-yarn pores of the fabric are the limiting mass transport ...
in this paper, finite element model of woven fabric target has been investigated which is impacted by a cylindrical projectile. fabrics are impregnated with shear thickening fluid (stf). the effects of the (stf) have been considered as frictional effect. the stf has been made (nano silica and polyethylene glycol (peg)) and then diluted by ethanol proportion of 3:1. yarn pulling out test from in...
