The Rise, Expansion, and Decline of the Italian Wool-Based Textile Industries, a study in international competition, transaction costs, and comparative advantage. This revised study seeks to examine the rise, expansion, and ultimate decline of the Italian wool-based textile industries over a period of six centuries from ca.

The transaction costs model is used to explain in particular which branches of this textile industry fared better and which fared worse during the Commercial Revolution era ca.

One of the major errors in the literature is the failure to distinguish between the two main branches of the wool-based cloth industries, the technology of their industrial production, their relative prices, and markets, and the impact of transaction costs in international trade.

For much of this era, the leading branch was the luxury-oriented woollens industry Old Draperies , based on very fine, short-stapled English and then Spanish merino wools, producing fulled, heavy-weight, and generally high priced cloths. In the earlier and later periods, the other branch prevailed New Draperies : the lighter-weight unfulled , generally coarser and cheaper fabrics that were either full worsteds cheap, coarse, long-stapled wools or serges hybrids with worsted warps and woollen wefts.

The transition from a predominance of the lighter, worsted-style fabrics to the heavy-weight woollens, throughout western Europe, took place from the s, with a rapid rise in transaction costs that were the direct and indirect result of a spreading stain of international warfare, especially injurious to overland trade routes, combined with a drastic fall in population, that engulfed most of Europe and the Mediterranean basin until the s.

That rise in transportation and transaction costs determined by market scale economies set a cost-price floor below which international trade in cheaper textiles became unprofitable: so much so that most West European wool-based industries re-oriented their production towards luxury markets, with far higher prices sustained by price-making monopolistic competition better able to withstand the rise of such costs, an impossible solution for those marketing cheap textiles as price-takers in Mediterranean markets.

Such problems were less severe for the Italian industries, whose markets were chiefly in the Mediterranean; and thus the transition to luxury production was far less complete than in the north. The comparative advantage model is based on the price that woollen-cloth producers in both the Low Countries and Italy had to pay in that luxury re-orientation: a total dependence on the finest English wools as the prime component of luxury quality.

From the late s, English monarchs took advantage of that dependence by imposing exorbitant taxes on wool-exports, with even higher taxes imposed on Italian merchants, ultimately depriving them of almost all such wools by the early fifteenth century. At the same time, English clothiers were able to weave luxury-quality cloths from the very same wools, but free of any such taxes, giving them an almost insuperable cost advantage over all foreign woollen manufacturers.

But England's comparative advantage in its wool supply, though finally giving them mastery of northern markets for luxury woollens, was undermined, during the later fifteenth, early sixteenth century, by the development of fine but much cheaper merino wools in Spain, which Italians could acquire with lower transport costs.

The other change undermining the supremacy of English and other woollens industry was the sharp fall in transaction costs by the late fifteenth, early sixteenth centuries: with the decline in warfare, the recovery and growth of population, and with technological advances in both ocean and land transport, especially the latter with a major transition in long-distance trade from maritime to overland continental routes. Along with that decline in costs came a revival and expansion of the lighter, cheaper textile industries, though chiefly in the Low Countries and England, more so than in Italy, despite the continued predominance of Mediterranean markets.

For woollens, the Italian industries, especially the Venetian, gained the comparative advantage in wools: with much cheaper access to now more expensive Spanish merinos. But in the Mediterranean and especially Ottoman markets the English finally gained supremacy over both the Florentine and Venetian woollens industries, by the later seventeenth century, from a new comparative advantage, in capital formation: from superior business organization the new joint stock companies and naval power large, heavily gunned, swift carracks.

The so-called General Crisis era of the later seventeenth century had again favoured maritime routes, and thus sea-power, over land routes. At the same time the Tudor-Stuart enclosure movements, in transforming English sheep -- from small sheep with fine short-stapled to larger meatier sheep with coarser, long-stapled fleeces, gave England's worsted-style New Draperies a comparative advantage in wool supplies over all its continental rivals, including the Italian; and by the s, both branches of the Italian wool-based textile industries had succumbed to foreign competition, and become moribund.

Wool in the Circular Economy

It's time to snuggle up with a material that has long been out of vogue. It comes after nearly forty long years of being destroyed by the trend for synthetic fibres. Wool is a sustainable, renewable and eco-friendly fabric, and spun wool has become the coveted textile of choice for fashion designers around the world, swamping the runways of London, Milan, Paris and New York Fashion weeks with knitwear so finely manufactured, it almost resembles silk. Where does wool come from? Having been used in clothing since the end of the Stone Age, wool goes way beyond fashion in its myriad forms. It can also be used to produce carpets, interior textiles like bedding and upholstery, insulation, and in some parts of the world, housing.

Recovery of wool wax and its use

A solvent is usually a liquid but can also be a solid or a gas. Solvents find various applications in chemical, pharmaceutical, oil, and gas industries, including in chemical syntheses and purification processes. Thinners are defined as chemical compounds that are introduced into the paint prior to application, in order to modify the viscosity and other properties related to the rate of curing that may affect the functionality and aesthetics of the final layer painting. Paint thinner, a solvent used in painting and decorating, for thinning oil-based paint and cleaning brushes. A Thinner may be a single solvent or a combination of solvent types. Often, specific thinners are required by the manufacturer of a coating to prevent damage to coating properties that may occur when an inappropriate thinner is used.

US2723281A - Process for degreasing wool and recovery of wool grease - Google Patents

As with many discoveries of early man, anthropologists believe the use of wool came out of the challenge to survive. In seeking means of protection and warmth, humans in the Neolithic Age wore animal pelts as clothing. Finding the pelts not only warm and comfortable but also durable, they soon began to develop the basic processes and primitive tools for making wool.

This gives wool its waxy feel and protects the sheep from the natural elements and seasonal climatic changes. After the greasy wool is removed during the shearing process, it is then subjected to washing and cleaning through the wool scouring process.

German Wool Industry

Recovery of wax from wool : Wool wax is a greasy substance secreted by fatty glands of the skin. Wool grease is recovered by centrifuging aqueous scouring liquors from the washing of greasy wool with detergents, often called centrifugal woolgrease. Chemically speaking, it is a complex mixture of wax esters of long chain fatty acids and alcohols, the latter including cholesterol, lanosterol and dihydrolanosterol. Centrifugal woolgrease is often considered by buyers to be of the best quality, especially if it is passed through 2 or more centrifuging steps. Industrial uses include fuel, lubricating greases, concrete mould lubricants, rust preventatives. Woolgrease is also an important component in many leather softeners. Lanolin is graded based upon its colour and presence of impurities, with the highest grades being white or very pale yellow in colour.

Fiber production

Picking up on the need for a more detailed understanding of the end of life destinations for wool garments, research conducted by the International Wool Textile Organisation IWTO and partner Australian Wool Innovation AWI has found substantial evidence for positive environmental benefits stemming from the regular recycling and re-use of wool garments. Under this system, the mechanical recycling of wool knitwear yields fibres of sufficient length to be carded and re-spun into yarns of pure wool or of blends. These yarns are then converted back into knitwear, providing a cost-effective wool fibre supply in ideal closed loop setting — the ideal recycling path. Due to the high quality and durability of the wool fibre, wool garments are inherently suitable for re-use and recycling.
