Regeneration of Silk Fibroin from Silk Waste and Its Applications.

Research studied the regeneration of silk fibroin powder from silk waste by dissolution and precipitation methods. Two different solvent systems, formic acid/calcium chloride and lithium bromide, regenerated the fibroin powder. A test of the regenerated fibroin powder as a finishing agent dissolved and applied the material to polyester fa..

Why do we need a lubricant?

In this paper, which was presented at the recent SDCANZ Symposium, the importance of fibre lubrication is reviewed. Following an outline of the function of the lubricant in reducing fibre/metal and fibre/fibre friction, the history of lubrication of wool and the primary requirements of a lubricant for the woolen spinning system, the steps..

Use of pesticides in cotton cultivation. Present situation

Environment is nowadays an economic feature as important as work or capital have been historically. This paper describes the use of pesticides in cotton cultivation and the way the European Union environmental policy affects this. The content of pesticides in cotton is limited to 0.05 mg/kg Yarn for: aldrine; captafol; camphechlor; chlord..

Italian silk industry in 1996

The current situation in the Italian silk industry is discussed including silk reeling, spun-silk and discontinuous fibre spinning, throwing, weaving and the trade in silk products. Statistics are presented for 1996 on the production, import and export of fresh cocoons, raw silk waste, tops thrown yarns, spun silk and noils and woven fabr..

Worldwide manufactured fiber survey: 1992 to 1998

A worldwide survey of production and capacity of manufactured fibres is presented. Synthetic fibre and cellulosic fibre are survey by country of production and by fibre type. Glass fibre production and acetate filter tow production figures are included.

Machinery to extract fibre from flax

William Tatham have developed a machine to extract usable fibre from flax. The decorticating machine is cheaper and performs better than traditional equipment. It works by removing the outer fibres from the woody core of the flax stem. The flax straw is then delivered to the machine by a bale opening hopper. After it has been removed the ..

Raw Materials Requirement Determination and Throughput Time Calculation in a Spinning Plant.

Research on flexible information control systems for small and medium companies in the textile industry investigated and modeled raw materials requirements and calculated throughput time, accounting for waste at every stage. Dr. Gellert ＆ Company Consulting GmbH's MRT system MSO (Model, Simulate, and Optimize) implemented the modeling pr..

Control of Roller Lapping.

Roller lapping results in substantial waste, poor quality products, and machine damage. Causes of roller lapping in cotton include honey dew contamination, high sugar content, immature fibers, oily contamination, excessive wax content, and oily seed coat

The Precise Effect of Fibrillation.

Lyocell fibers derive from a solvent process using wood pulp. An important characteristic of lyocell fibers is the presence of microfibers on their outer surface. Courtaulds' lyocell fiber is absorbent, biodegradable, and suitable for medical applications. Lyocell fibers have a smooth, circular cross section. Fiber structure consists of a..

Changes in Wool Colour. Part III: Processing.

Research assessed the clean and as-is color of seven lots of Australian merino fleece wool and three lots of Australian merino skirtings before processing and at various stages during scouring and top making, and measured raw wool and as-is incubated colors of rewashed top and blank dyed top. Clean color of raw wool was similar to the col..
