Received: 18 July 2017; Accepted: 8 August 2017; Published: 10 August 2017 Abstract: The presented paper concerns scientific research on processing a poly(lactide-co-glycolide- co-trimethylene carbonate) copolymer (PLLAGLTMC) with thermally induced shape memory and a transition temperature around human body temperature. The material in the literature called terpolymer was used to produce smart, nonwoven fabric with the melt blowing technique. Bioresorbable and biocompatible terpolymers with shape memory have been investigated for its medical applications, such as cardiovascular stents. There are several research studies on shape memory in polymers, but this phenomenon has not been widely studied in textile products made from shape memory polymers (SMPs). The current research aims to explore the characteristics of the PLLAGLTMC nonwoven fabric in detail and the mechanism of its shape memory behavior. In this study, the nonwoven fabric was subjected to thermo-mechanical, morphological, and shape memory analysis. The thermo-mechanical and structural properties were investigated by means of differential scanning calorimetry, dynamic mechanical analysis, scanning electron microscopic examination, and mercury porosimetry measurements. Eventually, the gathered results confirmed that the nonwoven fabric possessed characteristics that classified it as a smart material with potential applications in medicine. -

Making & Finishing Textiles
MAKING & FINISHING TEXTILES What & How This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement number 820937. INTRODUCTION Once we have turned our discarded textile products yarn, we then use this yarn to produce cloth, or fabric, which is then used to make textile products. To make fabric, there are three main production methods: weaving, knitting, and nonwoven technology. We will briefly describe these three methodologies in the following sections. Without finishing, however, no textile product is ready for use. In the final section of this chapter, we will discuss finishing techniques like dyeing and printing. Before we begin, however, we must provide a brief disclaimer. These areas of cloth production are huge industries. The amount of knowledge, technology, and variation in production methods is such that we cannot cover all of it. We will only discuss the basic principles in this chapter and leave out the more detailed information. KNITTING Knitting is a traditional way of creating fabric and garments by using needles to loop yarn into a pattern of interconnected stitches. These stitches are then joined together in a series of rows, which eventually form a mesh (the fabric). Garments are usually made up of a large number of stitches (often more than a few hundred). Knitting needles hold the initial row of stitches in place (so it does not unravel) while subsequent loops are pulled through the first row using the working needle. This process is repeated until the garment is complete. Knitting is a versatile technique that can be used to create a wide range of diverse and varied fabrics. -
Silk Fibroin Sponge Sheet for Skin Care
Silk Fibroin Sponge Sheet for Skin Care Kazutoshi Kobayashi Naosuke Sumi New Business Development Headquarters, Tsukuba Research Laboratory, Frontier Technology Development Center 1 Abstract Silk yarn has been used as fabric on account of inimitable shininess and texture, and also as surgical suture on account of high strength and bio-compatibility. By using fibroin protein that is the main constituent of silk, the utilization as the film, the powder, and the sponge is considered1). There were some reports how to form the sponge, but the strength of the sponge was insufficient. Therefore, the sponge has not been implemented yet 2). We have examined how to make the high-strength sponge, and have suc- ceeded in getting the sheet form of the high-strength sponge using the fibroin protein3). We propose our sponge sheet as skin care materials, because our developed sponge sheet maintains the good feeling of silk itself, and has the high water absorbency, the high water holding property, and the high adherence. 2 Key Points of the Development Product ・This development product comprising natural silk fibroin offers a uniquely soft and tender touch. ・Safety tests, including for cytotoxicity, skin sensitization and human patch were successfully conducted and a high level of biologi- cal safety was also confirmed. ・Skin care material with superior performance in terms of water absorption, retention, skin adherence and transparency com- pared to nonwoven cotton fabric frequently used in items such as face masks can be offered. 3 Development Background We started developing the sponge sheet for skin care by focusing on silk fibroin as a bio-derived material, produced by the silk Original worm, as part of work to develop life science- Cocoon Fibroin raw material fabrication technology related products compatible with changing Sponge sheet consumer behavior of recent years in areas such as the environment, safety and health. -

Engraving and Cutting Synthetic Suede with a Universal Laser System
Engraving and Cutting Synthetic Suede with a Universal Laser System Introduction A Universal laser system is ideal for cutting and engraving natural and synthetic fabrics. A Universal laser system can cut fabric more quickly and accurately than hand or knife cutting and eliminates edge fraying. A Universal laser system can also engrave a photograph, text or artwork directly onto the surface of many fabrics to create a very unique look. Some of these fabrics include felt, leather, denim, canvas, nylon, silk and polyester. Of the many fabrics that can be laser cut and engraved, one of the easiest and most popular to work with is synthetic suede. Synthetic suede, also known as Ultrasuede®, is a polyester or nylon microfiber material that has the look and feel of real suede. It is available in a wide variety of designer colors and cuts and engraves beauti- fully. Engraving into the surface of synthetic suede darkens the material and produces a high contrast appearance. Synthetic suede is easy to sew and can be used to create garments such as jackets, vests, dresses and skirts. It is also ideal for creating appliqués and all kinds of craft projects. In this tutorial you will learn how to use a Universal laser system to cut and engrave simulated suede to create a decorative throw pillow. Throw pillows are fun to make and a great introduction into the basics of cutting and engraving fabric. We hope you find the process rewarding and enjoyable. Sincerely, The Universal Laser Systems Training Staff © 2014 Universal Laser Systems, Inc Engraving and Cutting Synthetic Suede Section 1: Preparing the Artwork 1.1: In this tutorial you will learn how to engrave and cut the design shown in Graphic 1 to create a deco- rative throw pillow. -

Marvin, Fellow, IEEE observed that the shielding effectiveness of the nonwoven Abstract—Nonwoven carbon-fibre sheets are often used to materials we have available varies very little with frequency form a conductive layer in composite materials for up to several gigahertz (see Fig. 2), and therefore depends electromagnetic shielding and other purposes. While a large principally on the sheet conductance [1]. amount of research has considered the properties of similar idealised materials near the percolation threshold, little has been done to provide validated analytic models suitable for materials of practical use for electromagnetic shielding. Since numerical models consume considerable computer resource, and do not provide the insight which enables improved material design, an analytic model is of great utility for materials development.
