Definitions

  • the invention concerns in any case synthetic fibres, such as plastic fibres and absorbent fibres, such as viscose and cellulose fibres to produce a fibre web, which at least include one heat-treatment section for heating up the synthetic fibres at least to one in advance determined temperature, and at least one hydro-entangling section with liquid nozzles to aim a number of powerful liquid jets against one made of synthetic fibres and absorbent fibres combined fibre layer.
  • synthetic fibres such as plastic fibres and absorbent fibres, such as viscose and cellulose fibres
  • a such plant is known, where long, carded, synthetic fibres of for instance polypropylene or polyethylene are laid in a web shaped layer on the top side of a net shaped, endless wire's upper tissue, which while running simultaneously runs in a direction, which points towards the plant's outlet.
  • the fibre layer hereafter is guided through an oven, where the fibres are heated up to such a high temperature that they will be tied together with cross bonds in the affected areas.
  • a thermal bonding fibre layer has now been formed, serving as a framework and supporting web for absorbent fibres, such as viscose and/or cellulose fibres, which as web can be un-winded from a roller or applied in an air-flow with the help of a known forming head.
  • absorbent fibres such as viscose and/or cellulose fibres
  • a close-meshed wire transports hereafter the supporting web with the applicated fibres through a battery of water nozzles, which send a powerful water jets down against the fibres, which hereby are driven effectively into the underlying, frame-like supporting web.
  • hydro-entangling or spun-lacing.
  • hydro-entangling will be used.
  • the hydro-entangled web is dried in an oven, and finally the web is wound up in shape of a roller.
  • Fibre webs which are manufactured in this way, are for instance used for products as wet wipes, towels, drapes, and gowns.
  • the above described process can be varied in several ways, which however has in common that they all start with a carded fibre layer.
  • the layers will be of polypropylene, polyethylene, or viscose, or a mixture of such fibres.
  • the carded made supporting web is soft and suitable for absorbing and intimately connect with the applicated fibres.
  • the longitudinal direction besides the web has such a matching strength that the process can proceed without a large risk of web breakage, which could lead to expensive stops of production and losses of materials.
  • Another advantage is that during the hydro-entangling process hydrogen bonds are made between the fibres, to avoid that the finished product flock and mote by use or processing.
  • the synthetic fibres, which make up the supporting web are furthermore considerably more expensive than cellulose fibres, and since the known process requires that approximately equal size quantities are being used of the two fibre types, the resulting product becomes expensive.
  • the finished fibre web anyhow will suffer from the main lack that there exists an even big difference in the strength respectively in the longitudinal and transverse direction.
  • the strength scale is typically 5:1. Products, which are manufactured of such fibre webs, therefore may tend to part alongside during use. Thus it is easy to stick a finger through the product.
  • a further disadvantage is that the known plant due to the carding process is rather unfit for production of sandwich webs, where the carded fibres become a part of several layers.
  • the known plant can therefore not be used for production of one of today's strongly demanded products, which consists of two non-woven fibre layers with an intermediate air-laid fibre layer, which is tied together with the two others by the help of hydro-entangling layer, which is tied together with the two others by the help of hydro-entangling.
  • the purpose of the invention is to assign a plan t of at the opening mentioned character, which has a simple and cheap structure, which is easy to work with and financially favourable while running, and which furthermore can manufacture at a larger transition speed than known so far.
  • Another purpose of the invention consists of assigning a plant of at the opening mentioned character, by means of which a fibre web with a balanced proportion between the strengths respectively in the longitudinal and transverse direction can be manufactured.
  • a third purpose of the invention consists of assigning a plant of at the opening mentioned character, which is designed to manufacture fibre webs taking price and features into consideration for optimum proportions between the quantities of fibre types used for manufacturing the web.
  • a fourth purpose of the invention consists of assigning a plant of at the opening mentioned character, by means of which a fibre web can be manufactured, which has a more homogeneous and precise distribution of fibres than formerly known.
  • a fifth purpose of the invention consists of assigning a plant of at the opening mentioned character, by means of which a fibre web with tighter tolerances than formerly known can be manufactured.
  • a sixth purpose of the invention consists of assigning a plant of at the opening mentioned character, by means of which a sandwich fibre web easily can be manufactured.
  • the plant's remaining equipment is now made able to operate at optimum production speed, simultaneously the process becomes easy to control.
  • the fibres can be distributed homogeneously and precisely with an equal orientation in all directions, thus the finished fibre web achieves approximately same strength in longitudinal and transverse direction, and besides manufacturing with tight tolerances becomes possible.
  • a forming head which include a under the wire's upper tissue placed suction box, which is connected t o a vacuum air pump, one above the wire placed house with one or more fibre inlets, and one in the house above the wire placed number of rotary wings for while operating to distribute the fibres in a flush layer on the upper side of the wire's upper tissue.
  • a simple and cheap construction form for the plant can be constructed of a forming head for at a time to form both the synthetic fibres and the absorbent fibres, a hydro-entangling section, and an oven with sufficient high treatment-temperature to thermal bond the synthetic fibres in the affected areas.
  • the thermal bonding of the synthetic fibres takes place in the same oven, which is used for drying the hydro-entangled fibre web.
  • a specific thermal bonding oven is inserted between the forming head and the hydro-entangling section, the process can be controlled very precisely, because the temperatures in respectively the thermal bonding oven and the later drying oven can be adjusted to an optimum for the respective processes.
  • the fibre web is now stabilised, when it passes through the hydro-entangling process, which therefore can proceed with an optimum effect and without a large waste of loose fibres.
  • the plant can be successfully used for production of sandwich fibre webs, since the middle forming head then mainly is supplied with for instance cellulose fibres, while the two other forming heads are supplied with synthetic fibres or both synthetic fibres and cellulose fibres.
  • the invention regards also a fibre web, which is manufactured by the help of the above mentioned plant according to the invention, and which contains synthetic fibres as well as absorbent fibres. Due to the production process this web has a structure with a homogenous orientation of the fibres in all directions and a good balance between the strengths respectively in longitudinal and transverse direction.
  • manufactured fibre web can favourably have a percentage content of cellulose fibres of between 50 and 95, mainly between 60 and 90, and especially between 75 and 85, at which the web becomes substantially cheaper than the conventional fibre webs of this type.
  • FIG. 1 shows schematically a first construction form for a plant according to the invention
  • FIG. 2 shows schematically a second construction form for a plant according to the invention.
  • FIG. 3 shows schematically a third construction form for a plant according to the invention.
  • FIG. 4 shows schematically a fourth construction form for a plant according to the invention.
  • FIG. 1 a first construction form for a plant according to the invention can be seen.
  • the main components are a forming head 1 , a conveyor 2 , a hydro-entangling section 3 , an oven 4 , and a winder section 5 .
  • the forming head 1 consists of a house 6 with a fibre inlet 7 for synthetic fibres, for instance plastic fibres, and a fibre.
  • inlet 8 for instance cellulose fibres
  • a net shaped wire 9 having an upper tissue 10 and a lower tissue 11 runs above roller 12 .
  • a suction box 13 is placed, which is connected to a vacuum pump 14 , and above the wire's upper tissue 10 a number of rotating wings 15 are placed.
  • the vacuum pump 14 provides via the suction box 13 and the house 6 an air-flow, which from an unshown source for synthetic fibres and likewise an un-shown source for absorbent fibres, as for instance cellulose fibres, leads synthetic fibres and absorbent fibres into the house 6 via respectively the fibre inlet 7 and the fibre inlet 8 .
  • the air-flow flows down through the wire's upper tissue 10 , while the fibres are kept back on the tissue's upper side, where those are mixed and distributed by the rotating wings 15 in an flush and homogeneous fibre layer 16 with a random and even orientation of the fibres in all directions.
  • This conveyor 2 consists of a wire 17 , which overlaps the forming head's wire 9 and runs over rollers 18 .
  • the wire 17 has a lower tissue, which is placed on the upper side of the fibre layer 16 .
  • the suction box 20 which is connected to a vacuum air pump 21 and is placed above the wire 17 's lower tissue, generates a negative pressure, which holds the fibre layer 16 on to the wire 17 's lower tissue 19 , which thereby will be able to transport the fibre layer 16 to the hydro-entangling section 3 in the with the arrow shown direction.
  • This hydro-entangling section 3 consists of a relatively close-meshed wire 22 , which overlaps the wire 17 of the conveyor 2 and runs above rollers 23 .
  • the wire 22 has an upper tissue 24 , which is placed on the lower side of the fibre layer 16 .
  • a number of water nozzles 25 are placed above upper tissue 24 of the wire 22 , sending powerful water jets 26 down against the fibre layer 16 , which are held to the web by an underlying suction box 27 , which is connected to a vacuum air pump 28 . Water and loose fibres will be removed from the suction box 27 by the pump 28 .
  • the water jets wind the fibre web's different fibres together in a strong bond. A portion of the water fights at the meeting with the close-meshed wire 22 's upper tissue 24 besides back against the fibre web's lower side, supplying a flush and smooth surface.
  • the now relatively strong and well coherent fibre web runs into an oven 4 , which works at a sufficient high temperature to thermal bond the synthetic fibres in the affected area. Simultaneously the web will be dried.
  • a rotating roll 29 is equipped with a perforated wall, which allows a warm flow of air to pass.
  • the air-flow will be re-circulated as shown by the help of fans 30 .
  • the finished fibre web will be wound up into a roller of fibre web 32 in the roller section 5 , which fundamentally consists of a winder 33 with a driven roller 34 and an idler roller 35 .
  • FIG. 2 shows other construction form for a plant according to the invention and separates itself from the above described and shown in FIG. 1 first construction form by, a special thermal bonding oven 36 being inserted between the conveyor 2 and the hydro-entangling section 3 . Similar parts are therefore indicated with the same reference numbers.
  • the thermal bonding oven 36 is a continuos oven, which the upper tissue 37 passes through on a wire 38 , which runs above roller 39 .
  • the fans 40 serve the purpose of re-circulating the air across through the fibre web 16 and the upper tissue 37 of the wire 38 , which carries the fibre web.
  • the thermal bonding oven 40 works with a temperature, which is sufficiently high to bond the synthetic fibres together in the affected areas, however not that high that the fibres melt noticeably.
  • the process in the thermal bonding oven is easiest controlled, when bi-component fibres are used.
  • the core for example has a melting point of 180 Celsius and the shell a melting point of for example 135 Celsius
  • the temperature in the oven must be kept in a spot between these two temperatures to efficiently cross bond the synthetic fibres in the affected areas without risking the core to melt simultaneously.
  • Another advantage consists of the oven 4 , now just needs to work as a drying oven, and therefore can work with a here fore fitted lower temperature, which size furthermore is uncritical.
  • FIG. 3 shows third construction form for a plant according to the invention and separates itself from the above described and shown in FIG. 1 first construction form by, instead of only one forming head three exists placed after one-another 41 , 42 , and 43 .
  • Each of these forming heads are constructed in the same way as the first constructions form's forming head 1 . Similar parts are therefore indicated with the same reference numbers.
  • sandwich-fibre web typically consist of a soft thermal bonded top- and bottom layer with an absorbent core.
  • the sandwich-fibre web can for example have following combination.
  • the proportions between the synthetic fibres and the absorbent fibres such as cellulose fibres 10 - 5 . This means that 67% of the bottom layer consists of synthetic fibres and 33% of absorbent fibres.
  • the proportions between the synthetic fibres and the absorbent fibres such as cellulose fibres 3 - 27 . This means that 10% of the middle layer consists of synthetic fibres and 90% of absorbent fibres.
  • the proportions between the synthetic fibres and the absorbent fibres, such as cellulose fibres 7 - 8 This means that 47% of the top layer consists of synthetic fibres and 53% of absorbent fibres.
  • the process processes in a way that the first forming bead 41 will be supplied with the fibres for the bottom layer, the other forming head 42 with the fibres for the middle layer, and the third forming head 43 with the fibres for the top layer, thus the three layers will be formed in each layer's separate forming head 41 , 42 , 43 and successively will be laid on top of one-another. Subsequently the process continues in the same way as described for the first construction form.
  • FIG. 3 shown fourth construction form for a plant according to the invention separates itself from the above mentioned and in FIG. 3 shown third construction form by, now similar to the other construction form, and as shown in FIG. 2 , a special continuous thermal bonding oven 36 is inserted between the conveyor and the hydro-entangling section 3 . Similar parts are therefore also in this case indicated with the same reference numbers.
  • Product Card based according to Product features product the invention Content of thermal 50% 5%-45% bonding fibres Content of cellulose 50% 95%-55% fibres Length of thermal 12-60 mm 2-25 mm bonding fibres Length of viscose 6-60 mm fibres Length of cellulose 0-6 mm 0-6 mm fibres Length of alternative 2-25 mm fibres (for example absorbent fibres) Dry strength, 100 N/50 mm *) 25-50 N/50 mm *) longitudinal direction Dry strength, 20 N/50 mm *) 15-30 N/50 mm *) transverse direction Wet strength, 100 N/50 mm *) 19 N/50 mm *) longitudinal direction Wet strength, 20 N/50 mm *) 11 N/50 mm *) transverse direction *) gram weight 65 g/sqm 65 g/sqm
  • the inventive product's strength is favourable fairly identical in the longitudinal and transverse direction, while the conventional product's corresponding strength ratio is as 5-1.
  • the plant can, within the frame of the invention's protection scale after need be supplied with two, four, or a bigger number of forming heads, which besides do not necessarily need to be placed in a row just after one-another.
  • one or several further sections can be inserted to in dependency of the wished quality to treat the fibre web.
