Abstract

Description

A device for determining fiber content and the method of fiber content determination
The subject matter of the present invention is a device for determining the fiber content and the method of fiber content determination. The device serves in the quantitative evaluation of fiber content in plant material of fibrous structure: raw, dried and retted.
Determination of fiber content in fibrous plants is very important and also quite difficult. Often, the fiber content is evaluated without proper equipment, i.e. by crushing and breaking retted straw in hands. The fiber content of unretted, dry and deseeded flax stems ranges from 16% to 30%. The percentage of fiber content is calculated in relation to the dry mass of the stems.
It is known that the light yellow, light green, and celadon colors of flax demonstrate that plants come from early sowing which secures the most favorable conditions for the formation of fiber. The content of fiber in stems is high, and they were harvested at the optimum time: in early, yellow maturity when the plant tissues have not yet become lignified. Fibers from such plants are soft, delicate, elastic, and perform well in further steps of processing. Flax sown late is green and contains less fiber. Its brownish straw, of various shades demonstrates a late harvest. The lignification process is advanced, the fiber is brittle, difficult-to-divide, the straw contains low amounts of long fiber and retting will take much more time. The determination of the progress of retting in the case of such differentiated flax straw by evaluating its appearance, crushing between the fingers and breaking of the retted stem by hand is error-prone. In the patent application RU2275447 (published 2006-04-27) apparatus for handful processing of flax stock was presented. Apparatus has mechanism for grinding of flax stock wood and separating of pile from fiber. Mechanism for separating of pile from fiber is made in the form of crankshaft whose free ends are mounted in bearings and straight portion between shaft cranks is formed as shaft with sharpened plates fixed thereon. Stem wood grinding device comprises breaking plank extending in parallel with axis of rotation of shaft and positioned at adjustable distance from generatrix surface of rotation of straight portion of crankshaft. Crankshaft and breaking plank are incorporated within casing, which is open at material feeding side for feeding of material for further processing and connected with ventilation air duct for drawing air from apparatus casing.
In the patent application WO9922586 (published 1999-05-14) cutting device was presented. The present invention relates to a cutting device for cutting straw and similar material into pieces, of the type which comprises a driven shaft kept in a housing, where said shaft is provided with longitudinally proceeding rows of knife attachments for knives, which extends radially from the shaft and are provided with cutting edges. Said knives, under operation pass between a row of counter knives directed towards said shaft and preferably provided with cutting edges in the same way, whereby the straw material to be cut is fed towards said counter arms. The number of rows with knife attachment are at least six. The distances between three knife attachments in a longitudinally proceeding row, have a proportion of 4:4:5 of a repeating unit, where the arms in a rotation round at least forms two screw lines.
In the patent application RU2245546 (published 2005-01-27) the method for determining processing value of scutched flax was described. The method involves taking sample; providing complex evaluation of quality depending on handful length of scutched fiber, its color; varying in accordance with given properties, combed fiber yield and changing color of fiber after combing process; evaluating quality, with lengthiness of handful fibers, volumetric weight, variation coefficients in accordance with said factors and combed fiber yield being taken into account. The method increased precision and reduced time for determining number of scutched flax.
In the patent application RU2150702 (published 2000-06-10) the method of determining process value of scotched flax fiber was described. Invention relates to standardization of bast-fiber materials, particularly to quality control of scotched flax fiber to determine its process value. Method includes integrated evaluation of fiber quality depending on handful length and color of scotched fiber, coefficient of variation regarding given properties, gain of hackled fiber, and factor characterizing change in its color compared to color of scotched flax fiber. The method facilitated determination of process value of fiber.
,:5 Patent description PL75030 (published 1976-09-15) presents a device for the determination of the degree to which flaxen or hemp straw has been retted. According to this invention, the device consists of a pair of rollers, between which straw samples are fed.
In the patent description GB407706 (published 1934-03-20) improvements in and
10 relating to the drawing of bast and long leaf fibres were presented. A slip-draft device for use in a drawing- head for slivers of bast fibres such as flax, hemp, jute and ramie and long leaf fibres such as sisal and manilla comprises a pair of positively driven rollers one of which is driven by the other so that the surface speed of the parts in contact with the sliver is substantially the same and arranged so that they may separate in accordance
,15 with the thickness of the sliver without breaking the driving engagement. The device comprises a pair of fluted rollers, the roller being positively driven and driving the roller by means of the flutes. The part of the roller engaging the sliver is reduced in diameter, and the roller is mounted in a lever so that it may move relatively to the roller in accordance with the hickness of the sliver.
20 In the patent description GB191302016 (published 1913-05-08) improvements in machines for swingling or for breaking and swingling flax were described. In machines having pairs of co-operating scutching - drums provided with a radial and outwardly directed blast to prevent the flax fibres from winding about the drums, the shafts of the drums are hollow and provided with radial perforations which are
25 arranged so as to give the desired distribution of the blast. The air may be drawn or forced into the shafts.
In the patent description GB487711 (published 1938-06-24) and GB461712 (published 1937-02-23) improvements in serrating and breaking flax and other fibrous plants and apparatus therefore were presented. Apparatus for serrating fibrous material
30 for serrating or breaking flax stalks, comprises a pair of short rollers of relatively large diameter, e.g. eight to twelve inches, pressed into contact by springs at each end of the upper roller shaft, the roller being provided with stout, deep flanges at each end between which the roller closely fits and a serrating blade mounted on arms pivoted on the upper roller shaft fitting closely between the flanges with one edge abutting against the periphery of the upper roller and the other edge resting upon a fixed plate held in close contact against the surface of the bottom roller. Alternatively the bottom roller may be flanged. The blade is adjustably secured to a swiveling bracket mounted on a bar secured in the ends of the arms, and is pressed downwards by a spring acting through a spindle and a ball-joint. The material is fed to the rollers over a feed plate by fluted rollers, and after serration between the blade, the plate and the flanges is delivered by a pair of rollers or by pairs, which straighten out the serrated material.

Example embodiments of the present invention are presented below.
Example 1.
A sample of retted, dried flax straw is put on the table 9 and introduced roots first into the cylinders 1 and V_. The springs 3_ regulate the mutual pressure of the cylinders against one another, modulated by the topography of their external surfaces. Next, having initiated the engine 2, the sample is moved mechanically from the left side of the cylinders to the right, wherein non-fibrous parts of stems are crushed (broken). The crushing (breaking) is repeated three times, by placing the sample back on the table 9 and introducing it each time roots first through the cylinders 1 and JΛ The scutching/hackling unit ,5, 6, 7 is held ajar. The sample crushed in this way is than fed from the opposite side, in relation to the table 9, of the cylinders through the set of upper 5. and bottom 6 scutching/hackling blades. These are closed and made to interact using the couplers 4 and the engine is made to run in the opposite direction. The sample, pulled through the cylinders 1 and V_ onto the table and treated on the scutching/hackling blades is then subjected twice to the same procedure. Each time, it is fed into the cylinders with alternating ends. Next, the couplers 5 are decoupled, the upper frame with the scutching/hackling blades 6 is moved up and to the left, to the position marked with a broken line on the drawing. The bottom frame 7 is moved down to the position marked with the broken line. The described work cycle, repeated 2-3 times is enough to extract fiber from retted straw. The chaff and tow are separated from the fiber and collected in a container 9. The fiber extracted with this method is than subject to quantitative and qualitative evaluation. Example 2.
A sample of raw, dried flax straw is placed on the table H) and fed roots first into the cylinders 1 and V_ etc. as described above. The working cycles according to the description above are repeated many times, until most of the tow is separated from the raw fiber. This results in decorticated flax fiber.
Example 3.
A sample of raw, dried hemp straw is placed on the table K) and fed roots first into the cylinders I and V_ etc. as described above. The working cycles according to the description above are repeated many times, until most of the tow and chaff is separated from the raw fiber. This results in decorticated hemp fiber.
