Just-in-time production, or JIT, has probably received more attention in a short time than any other new manufacturing technique. Despite the extensive publicity and interest, few companies have implemented JIT in their manufacturing operations. If JIT provides all the benefits […]. If JIT provides all the benefits claimed for it, why have so few factories adopted it? The popular press, and even some technical articles, focus on the easily observable differences from batch production systems but ignore some of the more important but subtle features of JIT.

Dear readers! Our articles talk about typical ways to solve the issue of renting industrial premises, but each case is unique.

In reality, textile goes beyond woven and knitted fabrics. It actually starts from Felt. Felt is a material that requires neither the weaving technology, nor the sophisticated knitting technology.

Felt may be the oldest fabric known to man; it predates both weaving and knitting. Since felt is not woven and does not require a loom for its production, ancient man made it rather easily.

Some of the ancient felt remain were found in the frozen tomb of nomadic horsemen in the Siberian Tiai mountains and date to around BC. These tribes made clothing, saddles and tents from felt. Legends have it that during the Middle Ages, St. Clement who was to become the fourth Bishop of Rome, discovered the process of felt making by accident. It is said stuffed his sandals with tow short flax or linen fibres in order to make them more comfortable.

Clement discovered that the combination of moisture from perspiration and ground dampness coupled with pressure from his feet matted these tow fibres together and produced a cloth. After becoming a Bishop, he set-up a group of workers to develop felting operations, this made him the patron saint for hat makers, who extensively utilize felt to this day.

Manufacturing methods of felt:. Basically, there are two methods of manufacturing felt fabrics:. Wet felting:. This process uses the inherent nature of wool and other animal hairs, because the fibres have scale on them which are directional and the hairs have kinks in them. It is the combination of these properties that reacts to the stimulation of friction and causes the phenomenon known as felting. It tends to work well with wool fibres as their scales, when aggravated, curl and bond together to form cloth.

Raw materials:. Wet fitted fabrics are produced from wool, which grips and mats easily, and a synthetic fibre that gives the felt some resilience and longerity. Synthetics cannot be turned into felt by themselves using wet felting but can be felted if they combine with wool.

Typical fibre combination include; wool and polyester or wool and nylon. Other raw materials used include - steam, sulphuric acid used in the thickening process and soda ash sodium chloride which is used to neutralizes the sulphuric acid.

Cleaning, opening and blending process:. The fibres animal wool contain a lot of fats and are thoroughly cleaned and made free of fats and dirt by scouring process. Since some felts uses more than one type of fibre, the cleaned fibres must be mixed and blended together before any processing begins. Usually, bale openers are used to accomplish this purpose. These blended fibres are now passed into a carding machine using hopper feeders. This makes the fibres parallel to one another and delivers them in web form.

At least two carding machines carding cycles are employed by passing the first web through a transporter to a second machine; this produces a new web which is thicker and fully carded. The stuff has to be distributed as evenly and uniformly as possible both horizontally and longitudinally on the actual web makers.

Several different web are combined sandwich laid to create one thick web. Four layers of web considered a standard single roll, sometimes referred to as a batt.

Batts are layered in order to create different thicknesses of felt. The basic rule is that the quality of nonwoven bounded fabrics such as felt can only be as good as that of the fibre web or fleece the web has been made into. Since the carders are not equipped with any storage facilities, any mass fluctuation in the feed will reappear unchanged in the card web, and once the fleece has been formed it cannot in the course of further processing be made more even and the irregularities present often have a decidedly negative effect on the mechanical and physical properties such as strength fitter effect etc.

The manufacturing process:. The batts for making felted material must be hardened or matted together in order to create thick, densely felted material; this is achieved through the process out line below:. The batts are subjected to heat and moisture by passing them through a steam table. The wetted batts are fed into a plate-hardener that shrinks the width of the fabric. The plate-hardener consist of a large square flat bed with a large plate that drops down over the wetted hot batts, exerting pressure on the material and compressing it.

At the same time, the plate-hardener oscillates from edge to edge further matting the fibre to a specific width. Alternatively, a roller hardening machine can be used; here the batts are pressed by rollers rather than by plates. The above batts are fed into a fuller or fulling machine, which shrinks the length to specific measurement. As it shrinks, the felt becomes denser. The batts are fed through a set of upper and lower steel rollers that are covered with hard rubber or plastic and are molded with treads much like a car tire, enabling them to move across the felt.

The felt is continuously wetted with hot water and sulphuric acid solution. The upper rollers remain stationary as the lower rollers are moved upwards to put pressure on the fabric and push it against the upper rollers. All the rollers, both upper and lower move together forward and backward. The pressure, the acid, the hot water and the movement causes the batts to shrink in length, making the felt even denser. Example, a piece of felt that is 38 yards long may come out of the fuller at only 30 yards in length.

The wet felt has sulphuric acid residue and must be neutralize by running it into neutralizing tanks filled a sodium chloride soda ash and warm water solution.

The speed of passage at this stage is carefully timed. The neutralize felt is then run through a refilling machine in which heavy rollers run over the surface of the fabric one last time to smooth out any irregularities. If felts are to be dyed, the wet pieces are taken to a dye bath and if otherwise, the washed felts are finished in several ways.

Finishes include those designed to make the fabric water proof or moth proof. Then the product is finally passed to a calendaring or tendering machine. The felt is roll up and sent to a centrifugal dryer that spins out the water, while other companies have huge dryers in which the felt is pinned in place on a dryer bed. Once dry, some companies press or iron felt to ensure consistent thickness.

Some manufacturers use this ironing to make dense felt even denser as ironing can shrink it slightly. The finishing step includes placing the felt on a gauging table in which the edges of the felt are neatly trimmed. The fabric is now ready for packing, labeling and selling. Dry felting needle-felting :. A needle felted fabric is a non-woven fabric made from webs or batts of fibres in which special barbed felting needles on an industrial felting machine are used. The barbs catch the scales on the fibre and push them through the layers of web, tangling them and binding them together.

This needling action interlocks the fibres and hold the structure together much likes the wet felting process, and its popular for two-dimensional and three-dimensional felted work. With needle felting, any fibre will work even man-made fibre and hair.

All other wholly artificial felts are actually needle-felts. Manufacturing process:. A web or batts of fibre are transported by a feeding device between upper and lower hole-plates. The bearded needles periodically penetrate through the holes in the plates and through the batts. In every stroke, the barbs of the needle seized fibres and pull the fibres through the web creating fibre bundle. As the needle withdraws, the batt is released and moves a small step towards take-off rolls.

The level of web densification is among others a function of the number of punches per unit area of the web, the number of needles in the needle board. Attainable frequency of the needle board determines the performance of the machine. Kent Page Felted Fabric www. NancyEvBryk production of felt fabric - madehow. Joseph, M. Essentials of Textiles.

Analyses of what has gone wrong with American industry have returned, time and again, to the poor quality of American-made products and to the management philosophy responsible for that quality. To date, most of the available evidence has been largely impressionistic, and few managers have felt the need to question familiar, long-established approaches to the work of manufacturing. We no longer have that excuse. Garvin has spent several years studying the quality performance of virtually every competitor, American and Japanese, and every plant in a single but broadly representative manufacturing industry: room air conditioners. His findings document a bitter but inescapable truth. The competitively significant variation in levels of quality performance is immense.

Felt is a textile material that is produced by matting, condensing and pressing fibers together. Felt can be made of natural fibers such as wool or animal fur, or from synthetic fibers such as petroleum -based acrylic or acrylonitrile or wood pulp -based rayon. Blended fibers are also common. Felt from wool is considered to be the oldest known textile.

Most fabrics are woven, meaning they are constructed on a loom and have interlocking warp the thread or fiber that is strung lengthwise on the loom and weft the thread that cuts across the warp fiber and interlocks with it fibers that create a flat piece of fabric. Felt is a dense, non-woven fabric and without any warp or weft.
