Definitions

  • the present invention relates to a method of hydro- entangling a mixture of staple fibres and pulp fibres which have been formed on a forming wire with the pulp fibres lying on top of the staple fibres.
  • Hydroentangling or spunlacing is a method which has become increasingly popular in the manufacture of me ⁇ chanically bonded nonwoven fabrics.
  • the method involves projecting jets of water from rows of fine nozzles onto a passing fibrous web carried by a liquid-permeable conveyor belt or wire.
  • the water jets are operative in creating mechanical bonds between the fibres in the fibrous web and strong nonwoven materials can be pro ⁇ quizd by means of this method.
  • the choice of fibres and fibre mixtures for material manufacture is practically unlimited when the material is produced by the hydroentangling method.
  • Such materials have pro ⁇ nounced textile-like properties compared with other fabric cloths, and the entangling method provides a relatively high degree of flexibility with regard to the properties of the material produced, mainly because the properties imparted to the material can be varied widely by selection of fibres, fibre mixtures, fibre forming, degree of entanglement, wire structures, etc. As a result, the use of spunlace material has become more common.
  • the properties of spunlace material are also influenced by a number of other factors, in addition to the manner in which the fibrous web or mat is entangled. These other factors include the type of fibres included in a mixed material and the proportions in which the fibres are present. An important factor is the manner in which the fibrous web or ibrous mat to be entangled is formed, i.e. the manner in which the fibres are lain on the wire, the forming wire, which transports the fibrous web to the entangling station.
  • the formed fibrous web consists of two separate layers of mutually different types of fibre which have been lain with the aid of commercially available equip ⁇ ment, there is normally obtained a final product which pronouncedly two-sided to a greater or lesser extent, i.e. has a higher concentration of the one fibre type on one side and a higher concentration of the other fibre type on the other side.
  • the formed fibrous web consists of a homogenous mixture of two types of fibre, however, a homogenous material is obtained.
  • the object of the present invention is to increase the wear resistance, and thus increase the strength of the bonds between the fibres on the staple-fibre side of spunlace material manufactured from a formed fibrous web comprised of a lower layer of air-lain staple fibres and a top layer of pulp fibres, without appreciably increas ⁇ ing the energy input during the entangling process.
  • the fibre ends which project out from the under ⁇ side of the fibrous web are folded in towards the under ⁇ side of said web, and the subsequent entangling process causes these fibre ends to be securely bound to the fibres in the fibrous web.
  • This binding of the fibre ends to the underside of the fibrous web increases its resistance to wear.
  • these bound fibre-ends form a network on the underside of the staple fibre-side of the material which reduces the risk of. overlying fibre-ends in the material projecting out from said material in use .
  • the duration of the second entangling process is deter- mined so that a suitable number of fibre-ends will project out through the underlying wire.
  • the invention utilizes, and even amplifies, the occurrence of fibre-ends which project through the entangling wire, something which is undesirable in conventional entangling processes.
  • the fine-mesh wire used in the first entangling process maintains the uniformity of the fibrous web during said process, and the staple fibres and the wire together form a very fine network which prevents the short pulp fibres from being flushed or rinsed from the fibrous web.
  • a 1.5 denier dry- defibred pulp fibre having an average length of 2.5 mm.
  • These fibres are air-laid on top of a layer of staple fibres, which may consist, e.g., of PES, viscose, 0.8-2.2 dtex and 20-60 mm long, which have been air-lain on a forming wire with the aid of a conventional staple- fibre former, e.g. a former of the Curlator, Rando- webber, Ferrer K12, etc.
  • Air-laying of the pulp fibres can be effected with a pulp fibre former of the Danwebb type, Kr ⁇ yer type or some other conventional type.
  • the formed fibrous web is transferred to a fine mesh first entangling wire of 100 mesh and there entangled.
  • a fine-mesh wire in this stage of manufacture enables the smoothness of the underside of the formed fibrous web to be maintained during the entangling process.
  • the fine wire forms together with the staple fibres an extremely fine three-dimensional network which prevents the short pulp-fibres from being rinsed or flushed out of the fibrous web during the entangling process.
  • the entangling process is effected with the aid of commercially available equipment sold by Honeycomb Systems Inc. or Perfojet S.A.
  • the fibrous web Upon completion of the first entangling process, the fibrous web is passed to the second entangling wire of 60 mesh and of smaller open area, and is there again entangled.
  • the bonds between the fibres in the fibrous web obtained during the first entangling process ensure that the pulp fibres on the pulp-fibre side of the fibrous web will not be carried away by the water jets, and that there are not found, at least to any appreci ⁇ able extent, non-bound short pulp fibres which can be carried by the water jets through the relatively coarse structure of the fibrous web and flushed out through the coarse-mesh wire. However, the water jets will press loose fibre-ends through the coarse meshes in the wire. This takes place to a large extent at the beginning of the second entangling process, when the fibrous web has a relatively open structure.
  • the strength of the fibrous web increases very rapidly at the beginning of the high-pressure entangling pro ⁇ cess, whereas there is no appreciable increase in the total strength of the fibrous web after a certain time has elapsed. Consequently, continued entangling of the . fibrous web after this point in time, to ensure that remaining fibre ends which project through the wire will be firmly secured in the web, will not result in any appreciable increase in the strength of the material in its entirety and consequently a large energy input is required in the entangling process in order to provide, in this way, a wear-resistant staple-fibre side of a two-sided nonwoven material. Furthermore, the fine wire in itself represents a limitation to the energy input per unit of time, due to its limited dewatering ability.
  • the wear-resis ⁇ tance is achieved in a totally different manner while maintaining a low energy input in the entangling pro ⁇ cess. This is achieved by interrupting the second entangling process before the fibrous web has reached full strength, and by then transferring the fibrous web to a third, extremely fine-mesh entangling wire having a size of 100 mesh. During this transfer, the free fibre- ends that project down from the underside of the fibrous web are folded in against said underside and due to the fine-mesh size of the wire, the inwardly folded fibre- ends will be held pressed against the underside of the fibrous web over the major part of their lengths.
  • the fibrous web transferred to the third entangling wire is then subjected to a second, high-pressure entangling process in which the inwardly folded fibre-ends can be readily entwined in the fibrous web by the water vor ⁇ tices generated during the entangling process.
  • the reference numeral 1 used in the Figure identifies the transverse wires of the forming wire used in the second entangling process, while the reference numeral 2 iden- tifies the transverse wires of the forming wire used in the third entangling process.
  • the time at which the transfer from the second to the third entangling wire is effected is not particularly critical. For example, if the transfer is made before a maximum number of downwardly-projecting fibre-ends are obtained in the second entangling process, a wear- resistant stable-fibre side will nevertheless be ob ⁇ tained after the third entangling process, provided that the number of downwardly projecting fibre-ends obtained with the second entangling wire is not excessively small. No further downwardly projecting fibre-ends will occur in the subsequent third entangling stage, since the fine-mesh wire together with the inwardly folded fibre-ends and the outer layer of the underside of the fibrous web form a very fine, three-dimensional network.
  • the transfer is made shortly after obtaining a maxi ⁇ mum number of downwardly projecting fibre-ends in the first, high-pressure entangling process, the number of downwardly-projecting fibre-ends will not have had time to decrease to an extent such as to reduce the wear resistance after the third entangling process.
  • the third entangling process is also utilized to provide an essential contri ⁇ bution to the total strength build-up of the spunlace material.
  • the transfer to the third entangling wire shall therefore be effected when a "suitable num ⁇ ber" of downwardly projecting fibre-ends have formed.
  • a "suitable number” is meant a number of downwardly projecting fibre-ends sufficient to achieve the requi ⁇ site resistance to wear of the staple-fibre side after the third entangling process. This suitable number is appropriately determined empirically.
  • the present invention utilizes the phenomenon that fibre-ends project down through the entangling wire, in order to increase the wear resistance of the staple- fibre side of the manufactured spunlace material, this phenomenon being considered disadvantageous in conven ⁇ tional entangling methods. If the number of downwardly projecting fibre-ends is sufficiently large, a very fine network is formed on the staple fibre-side after the third entangling process, because the inwardly folded pulp-fibre ends are then firmly connected to the fibres present in the underside of the fibrous web. This network prevents overlying free fibre-ends in the fibrous structure from protruding from the resultant spunlace material produced in accordance with the inven ⁇ tion, when said material is used.
  • the mesh size of the second entangling wire is of deci- sive significance, primarily with regard to the length of the fibre ends which project out through the second entangling wire after the first, high-pressure entangling process. If the mesh size of the wire is too small, the network formed by the wire together with the outer part of the underside of the fibrous web will prevent a sufficient number of downwardly projecting fibre-ends of sufficient length from being obtained. With larger mesh sizes, there is a risk that holes or irregularities will occur in the fibrous web.
  • a 60-mesh wire was found suitable with the fibres used in the above example.
  • the average length, 2.5 mm, of the pulp fibres was thus about six times greater than the mesh width.
  • the third entangling wire had a fineness of 100 mesh.
  • the total energy used when entangling the fibrous web was 500 kWh/tonne, of which a third was used for each entangling step.
  • the sizes of the wires used in respective entangling processes must be adapted to the nature of the fibres present in the fibrous web, in order to obtain a satisfactory result.
  • a good result can be achieved with those fibres suitable for use when practicing the inventive method by a suitable combina ⁇ tion of wires within the range of 80-100 mesh in the case of the first entangling wire, 40-80 mesh in the case of the second entangling wire and 100-200 mesh in the case of the third entangling wire.
  • the inventive method enables spunlace material that can be used in operating theatres to be produced at a much lower energy input than the inputs of earlier known entangling processes that are effected on the basis of a fibrous web which has been formed by air- laying pulp fibres on top of an air-laid layer of staple fibres.
  • the amount of material wasted when practicing the present invention is also far less than the material wasted when practicing earlier known methods.
