Page Technology in Australia Australian Textiles - The 20th Century continued The cotton and flax sectors of the textile industry had not been idle all the while, and were establishing themselves during the post-war years. In , in Sydney, George Bond later Bonds Industries commenced spinning cotton yarn and began the manufacture of towels and knitted garments and, in , the Airedale Weaving Mills, of Melbourne, began weaving cotton tweeds and engineer's twist. The latter company pioneered the cotton-weaving industry in Australia.

Textile process dusts, in particular wool and cotton, can also cause byssinosis cotton dust , occupational asthma and respiratory irritation — see more information below link to more info below.

For the wool industries typically dusty operations include opening, blending, carding, and backwinding. For cotton, control measures are likely to be required for most early processes including raw material handling, opening, carding, drawing, combing, beaming, ring spinning, and high speed winding.

Cleaning should be done using something like a vacuum cleaner, not a broom or brush or compressed air. Byssinosis - an illness associated with exposure to cotton dust with both acute and, in some cases, long-term effects. The numbers of compensated cases have been in single figures for more than the last decade Table IIDB The number of death certificates per year with byssinosis recorded as the underlying cause of death has been also low in the last decade; typically, there have been fewer than five deaths and in there were 2 deaths Table DC The starting point should be to stop the dust being generated altogether.

Whenever possible, try to handle dyes in dust-free or reduced-dust forms, for example, in solution, as granules, pellets, pastes, or dedusted powders, rather than as dry powders. Contact your suppliers for advice. It may be possible to eliminate some stages in a process, for example, by:. Working carefully with the dye powder product can reduce the amount of dust released considerably, so provide training in good handling practices.

More information about safety with dye dust can be found at Dyes and dyeing. Exposure to cotton dust has long been associated with the chronic respiratory disease byssinosis.

The incidence of the disease is related to the number of years a person is exposed to the dust and the concentrations of airborne dust to which they are exposed. Most cases are associated with earlier parts of the processing where dust levels are generally higher. It is not known which component or components of the dust cause the disease. However bleaching or other wet treatments reduce the incidence of the disease.

Illness associated with exposure to wool dust is less well defined. Typically, chronic bronchitis, breathlessness, persistent rhinitis runny or stuffy nose and persistent conjunctivitis itchy or sore eyes are seen. The incidence of these symptoms is related to concentrations of airborne dust and to the number of years a person is exposed. There does not appear to be a link with any particular stage of wool processing.

The WEL for cotton dust is 2. Wool process dust is the term used to describe the dust generated in the production of woollen and worsted textiles. This includes all factory processes from the receipt of the raw wool up to the finished product in the case of carpet manufacture and up to, and including, weaving, knitting or non-woven cloth production. It does not cover agricultural processes, including any sorting or baling done on the farm.

It does not include other speciality fibres - such as goat hair including cashmere and mohair , camel hair or alpaca. These fibres differ from wool in structure and it is not certain that the composition of the dust or the potential health risk is the same as with wool process dust.

Batches of cotton and wool vary in their dustiness, depending on the quality of the raw material, the treatment it receives and the processes through which it is put. You should consider the reduction of dust as one of you objectives when introducing new processes or machines or when changing existing ones.

Control of exposure to dust has to be achieved without the use of respiratory protective equipment RPE if this is reasonably practicable. Often the most effective approach is to enclose machinery as much as possible and then to use LEV to control dust escaping from essential openings.

Good general ventilation is necessary to prevent the build up of high background dust levels. Exposures can also be reduced by removing workers from close contact with the process, for example by eliminating the need to enter blending bins or by placing workers in booths fed with filtered air where this is feasible.

Cleaning machinery by 'flapping down' with cardboard or by using compressed air is strongly discouraged as high levels of dust can be generated by disturbing settled dust. A better alternative is to vacuum with a type H cleaner suitable for industrial use or to use a a piped vacuum system.

If brushing floors cannot be avoided, then dust generation can be reduced by first moistening the floor with a water spray. The filters in dust collection systems will either be under positive or negative pressure depending on whether the fan is on the dirty or clean side. Filters under positive pressure blown filters should be enclosed or located in a separate filter room since any leak in the filter will cause dust to be blown into the working area.

Any air returned to a workroom from a dust collector should not significantly increase the exposure of workers. Dust concentrations in returned air may need to be further reduced using a high efficiency secondary filter, water spray scrubbers or electrostatic precipitators.

Determination of the appropriate measures is a matter for specialist advice. Unless the system is designed with rotary valves to be emptied while running, dust collectors should be emptied with the system switched off and using a method which prevents the release of dust. One option is to use a disposable bag in a collector bin. Emptying dust collectors is a very dusty task and RPE should be worn if dust cannot be adequately controlled during emptying.

A failure to ensure filter systems are regularly emptied and well maintained will lead to a dropping-off in their performance and will make their eventual emptying an even more difficult and dusty task. The inflowing air at a vacuum conveyor, or any LEV provided at the feed point of opening machines, will not significantly reduce the exposure of the person feeding the material manually.

Therefore, the aim should be to reduce the amount of manual handling to a minimum. Some handling may be eliminated by changes in working practice. Automation may also be feasible; in the cotton industry automated bale pluckers fitted with extraction have reduced operator exposure significantly. LEV may be practicable in some instances, eg at sorting tables. For some manual operations adequate control of exposure may only be achieved by using RPE in addition to other measures.

Exposures can be reduced by removing dust from machinery by vacuum cleaning as far as possible before work starts. Where there is a permit-to-work system, cleanliness of the machine should be one condition of entry on the permit. Respiratory protective equipment may be needed to adequately control exposure. These aim to increase the quality of the yarn by blowing material off machines and then vacuuming up the settled material at ground level.

They are not designed as exposure control measures and their effect is variable. In some instances local dust concentrations in air will be increased. Manual opening and lapforming are likely to generate exposures which exceed the MEL. Lower production rates, greater enclosure and well-designed LEV are all factors which may justify a lower extraction figure.

For newer machinery, the supplier should specify an appropriate rate. Under-machine extraction located inside the enclosure will remove settled waste and trash and should be provided. Manual clearance of trash creates a great deal of dust and would lead to exposures generally exceeding the MEL. Whether suction systems for automatic take-up of broken ends improve exposure levels is less clear. Where low and medium count cottons are spun, exposures may be high.

These processes are described as ring doubling or balling in some mills. Local exhaust ventilation can be fitted but will require careful design. Under-floor extraction at spinning processes is effective as part of the general ventilation. In addition, less operator attendance is needed. The requirement for close supervision will generally limit the application of LEV. Unless extraction is provided, dust carried on the induced air flow from the creel to the beam will collect in the stagnant area just beyond the beam.

This is usually where the beaming attendant stands. A fixed receptor hood, with screens, fitted above the beaming machine headstock can be an effective method of control, provided it removes the necessary large volumes of air. General room ventilation moving air in the same direction as the induced air flow to extraction sited beyond the beam may also be effective, since it prevents stagnation of the dusty air.

Experience shows that it is possible to reduce exposures to below the MEL at beaming through the provision of good general ventilation. If it is not possible to provide enough ventilation, a less satisfactory approach is to move the operator to one side of the beam and provide a booth with filtered air supply. Respiratory protective equipment would then be worn during times outside the booth.

Assessment of working practices should ensure that manual handling of the raw material is kept to a minimum. Nevertheless, RPE may need to be worn by operators who feed material from bales manually. Fibre is often conveyed pneumatically at early processing. Efficient systems will be needed to separate the fibre from the high volume of conveying air before this is vented at the delivery point.

Vacuum conveyor systems within the bin do not provide significant capture of dust. The process is not amenable to engineering control and the use of RPE is essential.

Wherever the opportunity arises bin emptying should be automated, through the introduction of moving bin emptiers or similar plant. In both automated and traditional blending bins, dust may build up on bin roofs.

To prevent this, some bins are now fitted with canopies over the perforated ceiling which exhaust to a dust filtration system. The decision on what measures are reasonably practicable will depend on an assessment of exposure, taking into account the most dusty blends which are processed. Dust emissions can be reduced by the provision of close fitting covers to those parts of the machine throwing off dust.

Further improvement can be made by fitting extraction to the covers. The covers would be in addition to, and not in substitute for, perimeter fencing. Respiratory protective equipment may be required for certain operations such as manual fettling. Vacuum fettling systems have the added advantage that they can be extended to provide vacuum cleaning for other parts of the workroom.

Control is complicated by the constant close attendance needed from operators which makes enclosure difficult, and by the many sources of dust. Nevertheless, there are a number of ways in which the problem can be tackled:. When calculating the relative costs of engineering controls and RPE, long-term costs should be used. Initial costs of RPE may be comparatively low but the cost of replacement and maintenance must be added.

The family business is currently run by the fourth generation of Vannestes : Alex Vanneste. We are modifying shortening and refining the long-staple flax and tow into a fiber with the characteristics of cotton, a artificial or synthetic fiber that is suitable to spin on the short staple ring or rotor spinning system. We are certainly the only linen tops supplier offering dyed colors.

Yarn consists of several strands of material twisted together. Each strand is, in turn, made of fibers, all shorter than the piece of yarn that they form. These short fibers are spun into longer filaments to make the yarn. Long continuous strands may only require additional twisting to make them into yarns. Sometimes they are put through an additional process called texturing.

The Belfast linen industry

There are probably many items of clothing within your wardrobe that are made of linen — but how much do you actually know about it? This article will give you all of the essential information that you need to know and answer some of your burning questions like "How is linen fabric made? The history of linen can be traced right back to the Ancient Egyptians, who valued linen so much that they even used it as currency. Linen was only usually worn and used by those in the upper classes, and this continued to be true when the Greeks started using linen. The Hugenots eventually brought linen manufacturing over to England and Northern Ireland — and since then, linen has been made all over the world. Just like cotton fabric, linen is made from a natural source — a plant. Linen is created from the fibres that naturally grow as part of the flax plant, a plat that grows all over the world.

Processing and Spinning Flax

After drying, the flax stems were bruised and broken using a machine called the brake. Alternatively they were crushed with rollers revolving in contrary directions. The bruised flax was then inserted into a scratching frame and repeatedly struck with a flat wooden sword or scrutcher. This process separated the pieces of wood from the fibre. In flax mills breaking was performed mechanically. Once the flax was removed from the woody particles it was converted into yarn. In flax mills the flax was lifted to the top floor of a mill and separated into different lengths and the ends of the fibres were roughened prior to spinning. Heckling or hackling involved cleaning, splitting and separating the filaments of flax. Dirt and small fibres were removed using combs.

THE WEAVING PROCESS

Based in the North Part of France, in the heart of the world best growing regions for flax fibers, The Flax Company grows with its partners flax fibers which will be used in its productions of linen fabrics and home textile. We have developed strong partnerships in France and Belgium with the scutching mills, with the flax spinning and weaving mills in China and with a stitching factory in India. Consequently we are able to offer traceable goods of highest quality at best price conditions.

These hemp yarns can be used in both industrial knitting and weaving machines to manufacture textiles to your own specifications. In both systems, the higher the number, the thinner the yarn. Hemp machine yarn is used for making textiles.

Customer Service. In our weaving process, we focus on quality, function and durability. We are uncompromising with yarns, bindings and weaves, and we are always on the lookout for new structures that can fulfil a need in the busy lives of our customers. Several years can often elapse from the start of a project to when the finished textile is in the warehouse, as we test and examine the weaves many times in the process. Did you know? Quality and yarns. Regardless of the material used in the weave, the focus is always on quality, functionality and durability. We work with several different types of yarns which each have their own benefits and characteristics. Cotton: We use Egyptian cotton in the vast majority of our products.

Flax is spun into yarn in the mill: yarn is manufactured into cloth in the factory; while etc., folding, marking, and casing, are carried on in the warehouse.

Linen, Hemp, & Flax Yarn (43)

During sorting, short fiber, flax grass, flax scrap and other debris are picked out to make the flax fiber retained its original identical form. After flax fiber sorted, it will become more supple, tough and shiny. The flax fiber processed is combed into longer size and higher strength of flax stripes. After hackling, the fiber will be straight and parallel, the fineness of the fiber is increased to meet the quality requirement for yarn spinning. The uneven sized flax stripes are combined and different thickness of flax stripes can be overlapped. The flax stripes are splitting and sorting further by means of stretching method and they are divided into thinner fibers for next production process. Meanwhile, during this process, impurities and shorter fibers can be removed. The flax stripes are stretched further, spun into twisted yarn stripes and winded into appropriate package namely winded on a special spool. Flax stripes are stretched and splitted, removing impurities and giving appropriate twist, to make them achieving certain strength so as to withstand the tensile of winding and unwinding.

The term textile industry from the Latin texere, to weave was originally applied to the weaving of fabrics from fibres, but now it includes a broad range of other processes such as knitting, tufting, felting and so on. It has also been extended to include the making of yarn from natural or synthetic fibres as well as the finishing and dyeing of fabrics. In prehistoric eras, animal hair, plants and seeds were used to make fibres.
