  Merino wool is popular among luxury clothing brands. It’s so fine that it can have a diameter of down to 17 microns. Merino sheep originated from Spain, but now most of the Merinos come from Australia (up to 80%). Merino needs to be processed because it can be spun to a yard and because the wool needs scouring to get rid of the fatty grease. offers scoured wool products.

Basic information on wool scouring is also available on the Techhistory site – Wool Scouring and Cleaning the Clip (see Topic 3 Useful Weblinks on CD).

The most informative book on the interesting history of wool scouring in New Zealand has been authored by Julie Bremner ().

The history of the Blackall wool scour in Australia is available. the scour liquors entrained in the wool fibers, and finally a drying process to yield the scoured product. Most wool scours operate at around 65°C in the scour bowls to take advantage of the fact that wool wax liquefies at about 40°C, with lower temperatures in the wash.

innovations, aqueous wool scouring remains the dominant method around the world. The development of aqueous wool scouring systems Traditionally wool was scoured in hot, aqueous solution of soap and alkali.

Synthetic detergents have largely replaced soap today Size: KB. from wool scouring mills. The character istics of these liquors are shown in Table II. * Flocor, Imperial Chemical Industries Ltd., Hyde, Cheshire, England. Chemical flocculations were carried out in the laboratory with or 1,ml samples by using a conventional jar test.8 Sludge settling rates and volumes were measured by using Imhoff cones.

Wool fibers have to be properly washed or scoured out before being processed into fabrics. This scouring process generates high pollutant wastes in two forms, an effluent liquid phase and a solid. into surface water [2]. The discharge of wool scouring effluent to public sewers and sewage works can thus give rise to serious problems.

After treatment, the scouring effluent is separated into three categories: grease, liquor and sludge. The grease may go for sale, the liquor is discharged to the sewage works, and the sludge needs to be.

WOOL SCOURING PROCESS AND SOURCES OF WASTEWATER The plant uses a counter-current flow wool scouring process, similar to that reported in the literature.1 The process flow diagram with the sources of wastewater discharge arrangement before modifications is shown in Figure 1. Six scouring bowls are used to clean the wool fibers.

Never use abrasive material, e.g. steel wool, scouring powder. Use only the paddle provided (same hardness) to prevent scratches. Applications Settleometers are used to determine percent (%) volume and/or settled sludge volumes (SSVs) for quantifying settling of sludge samples.

that is related to a very high concentration of wool wax and detergent in the scour liquor. The wool wax content of merino wool is % and most of it is scoured out. The scour liquor from the first bowl of raw wool scouring unit has the following characteristics I.

Three merino fleece wools of different characteristics were scoured in a pilot-scale Lo-flo machine under conditions designed to achieve minimum water consumption, uniformly high quality scoured wo.

For a better understanding of wool character and what constitutes a sound, healthy fleece I would refer you once again to “In Sheep’s Clothing” or to Anne Field’s book, “Spinning Wool, Beyond the Basics”.

The instructions found in this module “The Art of Scouring” are specific to sound longwools and crossbred wools. Recently consumers have become more and more concerned about animal welfare. Because of the traceability back to the farmer with Wool Integrity NZ™ we are now able to address these customer Integrity brand it is a great initiative that allows us to provide an “Integrity line” of standard types for our customers with the full assurance about the core values of Animal Welfare.

Wool that has been stored five or six months after clipping and is well dried contains less grease and cleans more readily than fresher wool. The loss of wool resulting from the scouring is estimated at 2 to 7 per cent., according to the strength of the lyes and the temperature of the water.

Wool grease derivatives are described in terms of their end-use. Element 5 Demonstrate knowledge of wool scour effluent and effluent treatment. Performance criteria Wool scouring liquor is described in terms of its components.

Yes, a little of the Power Scour (or of the Fibre Wash) goes a *very* long way. I have a large bottle because of the size of this project. I've washed a lot of wool already and made a noticeable but still small dent in it. I *may* make it through this whole project with the one bottle.

That's astonishing. Scour bowls are filled with a liquor primarily consisting of water, but also soaps, detergents and the contaminants that have been removed from the wool.

The wool is driven as a saturated mat along the top of the bowl, by sets of harrows. Both the wool and water enter from the same side of the bowl. Wool scouring effluent is continually becoming more difficult to treat due to improvements in scouring technology.

Effective scouring relies on: (1) removing contaminants from the fibre into the scour liquor, and (2) preventing the insoluble contaminants re. Scouring involves the greasy wool being fed into a machine where it is continuously transported through a series of bowls, typically between 6 and 8 bowls, containing wash liquor.

In the initial 2 to 3 wash bowls the wash liquors comprises warm water*, containing detergent and sometimes an alkali, and it is at these stages where most of the. was tested on several wool scouring liquors and rinse waters. The system, by creating a rapid torsional shearing action on the membrane surface, was able to prevent a significant build up of solids (wool wax and dirt) on the surface and in the pores.

As a result, the unit. Wool is fed through the feed hopper, scour bowls, rinse bowls and the dryer. In the scour bowl, which is enlarged at the top, the harrows move the wool across the top of the liquor in the bowl and contamination settles out of the wool into the settling tanks.

This scour bowl. In extreme cases, raw wool may contain as little as 30% fiber, 70% foreign matter, of which 45% is grease. Wooling waste originated from scouring, carbonizing, bleaching, dyeing, oiling, fulling and finishing operations. Scouring: Wool grease and foreign matters are removed by Scouring with wool in hot alkali, soap and soda ash.

The mechanisms of grease removal from raw wool by various scouring solutions were studied. The protein contaminant layer (PCL) played a key role and the "classical" mechanism of rolling up of the grease from the fiber was not significant in most scouring solutions.

The quality and surface characteristics of wool fabrics can be evaluated by handle evaluation methods. this is an invaluable book for a wide range of readers in the textile and apparel.

Raw wool scouring is typically carried out at temperatures below °F(60°C) with low cloud nonionic surfactants and/or anionic detergents sometimes in the presence of emulsified solvents. An alkali such as ammonia may be used, but the pH should not be above 10 for extended periods of time and temperatures in excess of °F(60°C) should be.

“Liquor is not necessary either for health or for so-called gracious living It is the cause of untold sorrow, suffering, and material loss, not to mention the spiritual implications of drinking.”. The process of destabilising the wool grease from wool scouring liquor was found to result from the activities of suspended microbes in the anaerobic sludge, which could successfully grow in WSE, rather than the bulk biomass as required in a conventional.

This book was published in London in and I could not find anything that makes me feel that it has been reprinted. Which is too bad, as it is an excellent book.

What follows is a description on how to sort a fleece for wool combing. Please remember that the book was written for industry. Longer wool tops receive a higher price for the topmaker, so greasy wool buyers usually pay premiums for low mid-break wool.

Price differences for POB can be seen across the entire clip. In fine wools, differences of around cents can often be seen between a very low mid-break of single figures, and a mid-break in the 80 to 90% range.

But before I add the wool I add the wool wash. The Power Scour works sort of like dye as far as how you determine the amount to use. It is based on the weight of the wool you want to wash. For these basins when I am washing about 2 pounds I add around 2 to 3 tablespoons in the first soak.

When I add the wool I push it down into the water. The merino wool contains around 50% grease and dirt. This is usually discharged as an emulsion in waste water during scouring.

Wool Water Scouring rejects large quantities of wastewater. The treatments of these highly pollutant wool scour effluents are. Textile - Textile - Dyeing and printing: Dyeing and printing are processes employed in the conversion of raw textile fibres into finished goods that add much to the appearance of textile fabrics.

Most forms of textile materials can be dyed at almost any stage. Quality woollen goods are frequently dyed in the form of loose fibre, but top dyeing or cheese dyeing is favoured in treating worsteds.

Wool is the textile fiber obtained from sheep and other animals, including cashmere and mohair from goats, qiviut from muskoxen, hide and fur clothing from bison, angora from rabbits, and other types of wool from camelids.

Wool consists of protein together with a small percentage of lipids. In this regard it is chemically quite distinct from the more dominant textile, cotton, which is mainly.

CASE HISTORY: PRETREATMENT OF TEXTILE WASTEWATER Randy Junkins, P.E.* INTRODUCTION The finished products of the textiles industry are manufactured from wool, cotton, synthetic fibers, or combinations thereof.

The processing which the raw fibers undergo are aimed toward: 0 Removal of natural impurities. 0 Providing desired qualities of sight, touch, and. Wool scouring, showing the point that wool drops into the first scouring bowl, is agitated and moves on to rollers to squeeze out the water before dropping into subsequent bowls.

Effective scouring relies on: 1- Removing contaminants from the fiber into the scour liquor and 2- preventing the insoluble contaminants re-depositing back onto the fiber (1).

For instance, a rum liqueur (or rum cordial) must be made with the “predominant characteristic flavor” of rum and be bottled at not less than 30% alcohol by volume (60 proof).Gin and Bourbon liqueurs/cordials have their own, similar, definitions.Eccoscour is a product of Organic Dyes.

It’s a powerful yet gentle wool scouring agent. It will clean and degrease the greasiest wool fleece yet is gentle enough for a tender cria fleece.

Using just 2 tablespoons for lbs of wool and 1 for non greasy fibers (alpaca, llama, mohair, yak, cashmere etc) its very economical as well.
