Definitions
- the present invention relates to flax fluff fiber which is intended to be spun on cotton-type spinning looms. It relates to also a process specially designed for the preparation of such a flax fiber.
- the spinning of textile fibers includes, in terms of processes and technologies, very large differences depending on the nature of the materials first which are brought into play. We classically distinguish preparation and cotton type spinning or more generally short fibers and the preparation and spinning of the wool type or generally long fibers.
- the linen industry is still distinguished from these two main types, due to the specificity of the structure of the flax textile fiber, this being composed of technical fibers consisting of fiber assemblies elementaries linked together by natural cements and materials encrusting. As a result, the linen industry has historically implemented its own preparation and spinning circuit, including in particular spinning wet and spinning dry.
- the flax fibers leaving the circuit preparation operations of the flax type are in no way suitable for being spun in the majority blend or pure on spinning looms of the wool or cotton type. Considering the very high productivity of cotton-type spinning looms, compared to those of the linen type, this presents a major drawback for flax.
- Cottonization of flax fibers go through different means mechanical, including cutting to length and mechanical action.
- the purpose of cutting to length is to give the flax fiber a length that is comparable to that of cotton.
- the purpose of mechanical action is to partially dissociate the elementary fibers composing the fibers techniques. It is in particular implemented with opener which are machines fitted with rotating drums fitted with spikes which attack technical flax fibers.
- the aim sought by the applicant is to offer flax fibers in fluff which are suitable for being spun on spinning looms of the type cotton in majority blend or pure.
- flax fibers the invention which are characterized by a height of the order of 18 to 21mm, by their percentage of fibers less than 10mm of the order of 10 to 12% and by the fact that 50% of said fibers have a length which is greater at 13mm.
- flax fibers of the invention are quite comparable to what is obtained for conventional cotton, for example Russian cotton of the PAVLON type. Through against the height of the fibers is, in this case, significantly greater than that of the Russian cotton in question.
- the flax fibers in fluff according to the invention are characterized by the fact that on the order of 20 to 30% of these fibers have a length greater than 40mm.
- This process involves treating fibers from tow scutching or flax all fibers, by operations following main: carding, doubling, stretching, cutting to length of the order of 50mm, and pneumatic pre-opening by passing through a fan typically open blades, the method includes a pneumatic opening operation by passage in an installation comprising two lined food cylinders needles, a perforated rotor fitted with blowing needles and a volute so that the fiber flakes from the open-bladed fan pass between the two food cylinders rotating in opposite directions slightly different speeds are detached from the fastest cylinder by the rotor lining, are opened by the air blown through the rotor and projected towards the exit of the volute.
- the method of the invention is characterized by the implementation on the one hand, operations which are classic in the preparation circuit traditional linen, namely carding, doubling and stretching, on the other hand cut to length operation and a pneumatic pre-opening operation which are conventional in the techniques of cottonization of linen and thirdly a specific operation pneumatic opening which is not usually implemented works in the linen circuit.
- flax flax having, from a cut to length of the order of 50mm, the claimed characteristics as to the height of the fibers, the percentage of fibers smaller than 10mm and the fact that 50% of these fibers have a length greater than 13mm.
- the pneumatic pre-opening is done by passing in an open-blade fan whose turbine speed is between 1500 and 3000rpm.
- the flax fibers of the invention have a fiber height of the order of 18 to 21mm, a percentage of fibers of length less than 10mm of the order of 10 to 12%; Moreover 50% of these fibers have a length greater than 13mm.
- height in the present invention, is the term which is commonly used in the linen industry to designate the average length of the fibers weighted or proportioned by the section of said fibers. For example, for a sample of three fibers having length l 1 , l 2 and l 3 respectively and for section a 1 , a 2 and a 3 , the height of the fibers in this sample is equal to (l 1 a 1 + l 2 a 2 + l 3 a 3 ) / (a 1 + a 2 + a 3 ). The height is therefore different from the arithmetic mean length which would be (l 1 + l 2 + l 3 ) / 3.
- the flax fibers in fluff had a 19.5mm high, a percentage of fibers of length less than 10mm equal to 11.4; in addition 50% of these fibers were 14.0mm.
- the preparation process specially implemented for obtaining flax fibers in fluff according to the invention comprises carding, doubling, stretching, cutting operations to a length of around 50mm, pneumatic pre-opening and opening pneumatic.
- Carding, doubling and stretching operations are traditionally used in preparation circuits, from a few types, short fibers, long fibers or linen. Their number and importance can be determined by the operator based on the starting material, depending on whether it is fibers from scutching tows or a flax type circuit with all fibers or that it is a mixture fibers from these two sources.
- the fibers coming from scutching tows, carding takes place on a linen type card in one passage from which a carding ribbon is obtained, in pots, from 20 to 25g / m.
- the doubling and stretching take place by successive passes on a doubling machine drawing machine type GN4, which regulates the ribbon coming out at around 20g / m.
- the cutting operation is carried out continuously on equipment of the type cutter, in which blades cut to length a sheet of ribbons previously pinched.
- the theoretical adjustment of the cut is fixed at approximately 50mm, knowing that length irregularities can possibly occur due to variations in ribbon thickness, lack of fiber control during passage or blade wear. Of such irregularities, which cause the formation of fibers having a length slightly greater than 50mm are not unacceptable in the process of the invention.
- the pneumatic pre-opening operation is done by passing the fibers thus cut in a fan with open blades.
- the fibers are fed radially by the suction circuit which opens at the axis of rotation of the turbine. They enter the blades open and are projected, during the rotation thereof, towards the discharge circuit.
- the fibers are therefore mixed by the blades fan straight, stirring which allows pneumatic pre-opening of said fibers.
- the rotation speed of the blades is 1500 at 3000 rpm.
- the pneumatic opening operation proper which follows passing through the fan with open blades, is carried out in a installation 1, as illustrated in the appended figure.
- Installation 1 comprises two coated food cylinders 2,3 an outer lining 4, a perforated blower rotor 5 coated with a exterior trim and volute 6.
- the two food cylinders are arranged in the immediate vicinity of the rotor 5 and the volute 6 forms an envelope around the rotor 5, said envelope having, in the direction of rotation of the rotor 5, a spacing of more more important with respect to the periphery 5 a of the rotor 5 and ending with a discharge pipe 7.
- the rotor 5 has on its periphery 5 has a lining 8.
- the two food cylinders rotate in opposite directions, one of the other, at slightly different speeds.
- the operation of the installation 1 is as follows. Fibers cut and pre-opened from the fan, under the in the form of flakes, are fed into a hopper 9 located above the two food cylinders 2,3, with a horizontal axis. The flakes lying in the lower part of the hopper 9 are received by the lining 4 of the food cylinders 2,3 and directed towards the rotor 5. The fibers constituting the flakes are detached from the fastest cylinder by the lining 8 of the rotor 5.
- the periphery 5 a of the rotor 5 has air passage openings, a blowing installation allowing the supply of a continuous air flow inside said rotor 5.
- the fibers which have been detached from the food cylinder 3 by the lining 8 of the rotor 5 are detached from said lining by the blown air passing through the rotor 5 and are projected through the volute 6 to the discharge pipe 7.
- significant opening of the fibers are much higher than the speed of rotation of the two food cylinders 2, 3.
- Flax fibers fluffed at the outlet of the discharge pipe are possibly compacted in a press to follow the circuit normal cotton spinning.
