Technical field
The present invention relates to a kind of method that is used for nonwoven fabric belts is reinforced by claim 1 preamble, a kind of by claim 7 preamble be used for implement the device of this method and by the fibrous nonwoven fabric by a plurality of melt-spinnings of claim 15 preamble.
Background technology
Known when making the nonwoven fabric of the lay formation of passing through a large amount of fibers, should in subsequent processes, reinforce, to improve the cohesion of the fiber in the nonwoven fabric nonwoven fabric.Except the reinforcement means of chemistry and heat, especially also adopt the mechanical consolidation method, wherein pass nonwoven fabric belts, so that fiber is twined mutually by additional structure.Recently, particularly the acupuncture of water bundle is significant as reinforcement means.Here produce the columnar water bundle under the high pressure effect, described water Shu Jiben vertically arrives and penetrates nonwoven fabric belts.At this moment the water bundle makes the fiber compression and produces vortex deformation at the point of impact, thereby forms surface (convex-concave) structure on nonwoven fabric.Make the flexible program that this surface forms the nonwoven fabric of structure and reinforcing for known in the prior art two kinds.
By the known method and apparatus of DE19828118A1, wherein above the guiding that is used for guiding nonwoven fabric belts has part, a nozzle box with a plurality of nozzle bores is not set by means of water Shu Jiagu nonwoven fabric.Nozzle box can be remained on nonwoven fabric belts top with moving like this, that is, can realize walking crosswise basically reciprocating motion in the traffic direction of nonwoven fabric belts by the drive unit of nozzle box.Produce a water bundle by the nozzle bore that is arranged on the nozzle box downside respectively by high pressure.Here, the reciprocating motion of the quantity of nozzle bore, nozzle bore layout and nozzle box is designed to, the feasible surface texture that forms the sealing of uniform as far as possible, smooth nonwoven fabric belts form.But this nonwoven fabric with surface texture of face shape is unsuitable for being used for holding additive, for example impregnating agent fully owing to lack volume area.
By US4,069,563 known another kind is used for reinforcing the method and apparatus of nonwoven fabric belts.Here the nozzle bore that forms on nozzle box keeps static with respect to nonwoven fabric belts.Nozzle box is fixed on the director element top at a certain distance.Here the water bundle that produces by nozzle box and nozzle bore substantially perpendicularly arrives the nonwoven fabric belts of advancing, thereby forms linear surface texture on nonwoven fabric belts.Can in nonwoven fabric, reinforce less or bigger area ratio as requested according to the different of nozzle bore quantity and layout.But this nonwoven is furnished with such shortcoming, and promptly linear surface texture causes the uneven intensity of nonwoven fabric.Determined that (CD) compares with horizontal direction, nonwoven fabric belts is also referred to as in this area on the direct of travel of machine direction (MD) has obviously higher intensity.Particularly when manufacturing had the bulk nonwoven fabric of little reinforcing area ratio, this intensity difference aggravated significantly.
Summary of the invention
The objective of the invention is now, what a kind of described type was provided is used for method that nonwoven fabric in advancing reinforces and the device that is used for implementing this method, can make with described method and apparatus area district with face characteristic and big volume (bulkiness) as far as possible uniformly, the surface forms the nonwoven fabric belts of structure.
Another object of the present invention is, a kind of nonwoven fabric with linear surface texture and high as far as possible intensity is provided.
The method of the feature of described purpose by having claim 1, the device of the feature by having claim 7 and having by the nonwoven fabric of the feature of claim 15 is realized.
The favourable improvement project of the present invention is determined by the feature and the feature combination of corresponding dependent claims.
Of the present invention being characterized as, be used to reinforce nonwoven fabric and the linear surfaces structure that forms based on a plurality of that be provided with, tilt distribution abreast mutually structure lines.Because when making fabric nonwoven cloth, form the fiber orientation of arranging usually along the nonwoven fabric belts direct of travel, can become the area district of such reinforcing by the structural linetype of tilt distribution, described area district causes forming not only longitudinally but also along horizontal fiber vortex deformation.Therefore form basically and the irrelevant equally distributed intensity of lead on nonwoven fabric.Another advantage of the present invention is that although the surface texture of reinforcing is arranged, fiber still has big freedom of motion in nonwoven fabric.For this reason, in the method for the invention, select fluid to flow to the amplitude of reciprocating cutter like this, that is, make the point of impact on nonwoven fabric belts (line of formation) of giving birth to not intersect with an imaginary separator bar by adjacent fluid miscarriage.The surface region of the reinforcing that therefore, produces in nonwoven fabric shows as uniform fibers vortex deformation and entanglement basically.Advantageously in nonwoven fabric belts, avoided linear surperficial wire harness have dual vortex deformation overlapping and crosspoint.
According to the quantity of nozzle bore and the layout of nozzle bore, (convex-concave) structure line in nonwoven fabric belts can be designed to have different inclinations angle with respect to the nonwoven fabric belts direct of travel.For the implementation structure line is the tilt distribution of acute angle as far as possible, such method flexible program is particularly preferred, and in this scheme, the reciprocating motion of fluid stream is carried out with (reciprocating) guiding speed less than the gait of march of nonwoven fabric belts.Therefore nonwoven fabric moves sooner than the fluid stream of transverse movement in the unit interval.
