Linen: The Manufacturing Process and How to Care for Linen Fabrics

Be itkn'ow'nthat I, J OHN HAMrsoN, a subject of the King of England, residing at Tangley Mere, Chilworth, in the county of Surrey, England, have invented certain new and useful Improvements in Apparatus for Separating Dust, Dirt, Leaves, and other Impurities from , Hair, Cotton, and other Fibrous Materials; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved apparatus for separating dust, dirt, leaves and other impurities from all kinds of fibrous materials, such for example as wool, hair, cotton and the like. The machine is of the type wherein a chamber is provided, one or more of the walls of whichare composed of grids, sieves or the like, such chamber having, preferably at the lower part thereof, a shaft or shafts provided with fans or heaters, suitable inlet and outlet orifices being provided for feeding in the untreated fibrous materials, for withdrawing or expelling the treated product and for removing the impurities which have been expelled from the material.

I have found in practical working machines of the aforesaid description that various difficulties are experienced, for instance, the dust and impurities of some of the materials are not drawn away sufliciently quickly after being expelled by the beating and blowing to which they are subjected by the rotary heaters.

My present invention relates to an improved form of such machines, wherein improved means are provided for removing the dirt or dust expelled from the fiber, thus causing a more rapid and efiicient treatment of the material. My apparatus consists broadly of a chamber provided with grids or sieves having a shaft furnished with heaters mounted preferably horizontally near the bottom thereof, an inlet aperture opening into the interior of the said chamber, and an outlet aperture closed by a suitable door or the like.

This chamber is mounted in another outer chamber formed with unperforated sides and comor spaces thus formed nozzles are led, which may be connected with rotary fans or other suitable means for produclng a strong current, say,'of air, which current of air, for.

Below the inner chamber is a receptacle for the dust and other material expelled. Means are provided for expelling the treated product, for carrying away the dust and refuse ejected from the machine and for carrying away any half treated material which may escape through the grid, to further apparatus for more fully treating the same.

I will now proceed to describe by way of example one particular form of machine embodying the principles of my invention. In this case the inner chamber is formed somewhat elliptical in shape in cross section and has extending along each wall a sieve or grid. At the bottom of the elliptical chamber is mounted a horizontal shaft provided with a number of b'eaters or fans and entering the chamber at some little distance above the beater or fan is an entry pipe leading to a suitable hopper or the like for feeding the machine.

The elliptical chamber has at the top a suitably hinged flap. The elliptical chamber a is closed by sheet metal or the like coming at some distance from the grid, in such a way that two spaces are formed one on each side of the chamber. The outer chamber thus formed is prolonged downward into a lower chamber from which opens an outlet passage and such chamber has at the bottom a conveyer for the purposes hereinafter explained. Opening into such space formed between the perforated walls of the inner chamber and the walls of the outer chamber, is a nozzle or there may be more than one communicating with a blower.

In a companion case filed Way 6, , No. The chamber a is elliptical in its general outline and its lower part, beneath the beaters e, is imperforate. Surrounding the chamber a is a casing m, which forms two spaces a and 0 one on each side of the chamber. The inclosed spaces a and 0 are in communication with the chamber a through the grids Z and c.

The casing m continues downward and forms a lower chamber p, which has working at the bottom a conveyor of suitable construction. When the flap h is opened, the chamber a communi "ates with a passage '1' which leads to a suitable conveyor. The space it has fitted therein a deflector plate '0. The action is as follows :The material to be treated is fed down the pipe 7 into the chamber a, the heaters or fans 6 are set working and beat and blow the material,.

While this is taking place the air fan 8 is blowing air through the pipes t and 76, down the spaces at and 0, so that all the dirt and refuse passing the grids is'driven into the lower chamber 1. The foggy floating portion of this dust is drawn off through the opening 9' and passes to an ordinary cyclone separator, the remainder going to the bottom of the chamber from where it is carried by a perforated conveyer which again separates the dirt from any fiber which may have passed through the grids with it.

I may vary the constructional features of my invention to suit requirements without departing from the principle of the same and I may combine, if found desirable, one or more chambers of the class described in series in order to form a plant, varying the arrangement to suit requirements.

Types of Machines Used in Textile Industries

Scutching is a step in the processing of cotton or the dressing of flax or hemp in preparation for spinning. The scutching process separates the impurities from the raw material, such as the seeds from raw cotton or the straw and woody stem from flax fibers. Hand scutching of flax is done with a wooden scutching knife and a small iron scraper. The end products of scutching flax are the long finer flax fibers called line, short coarser fibers called tow , and waste woody matter called shives. In the early days of the cotton industry the raw material was manually beaten with sticks after being placed on a mesh, a process known as willowing or batting, until the task was mechanised by the development of machines known as willowers.

LINEN TYPE SPINNING

Linen has exceptional properties thanks to nature, its composition and the structure of the flax fibers. But how does this wonderful plant actually become a yarn? Linen type spinning describes the spinning process of the linen plant, which also called flax.

Eman is a writer and textile engineer. She obtained her bachelor's degree in textile sciences from the Faculty of Applied Arts. Linen fiber is a cellulose fiber derived from the flax plant trunk. Linen yarn is woven from the long fibers found behind the bark in a multi-layered stalk of the flax plant. In order to restore cellulose fibers from the plant, the wooden trunk and the inner pith pectin , which binds the fibers together in a clump, must be eliminated away.
