Abstract
The present invention relates to a filamentary nonwoven fabrics made of the materials-the fiber created by the non-fusion spin not fabricated in the spin stick type non-weaving process. The neotype nonwoven fabrics with novel performance combination are made through the filament combined sometime in the nonwoven process. The manufacture can be performed on the ordinary stick type non-weaving device, wherein one part of the tension device acts on the filamentary conveyor not made in the spin stick type non-weaving process.
Description
Technical field
The present invention relates to a kind of novel bondedfibre fabric, be used for making the new method and the application in weaving and industrial application thereof of bondedfibre fabric.
Background technology
The plane configuration thing of weaving is exactly known for a long time.The technology that is used for making this plane configuration thing constantly is improved.
Though for example loom belongs to the most ancient in the world machine, also updating up to today.Even because the raising of filling speed mainly is to improve constantly weaving speed, but the basis of processing procedure is before weft yarn can move again round about, to make weft yarn drop to 0 in the speed of two edges of fabric.
Knitting also is a kind of very ancient plane configuration thing manufacturing technique that can utilize machine to carry out.Knitting be one to each independent long filament, the perhaps process that in modern circular loom, also has guiding ground to arrange with the form of tow.
The common ground of above-mentioned two kinds of methods is to adopt continuous long filament as semi-finished product.
Felt and long wool tweed (Loden) are another kind of spinning plane configuration things.Felt is undertaken by the layer to a plurality of particularly wool fibres that stack mutually that fulling milling or acupuncture obtains.Therefore felt also can be regarded the fiber matting that wool is made as.The long wool tweed at first is made into by knitting wool, and the woolen knitwear that will obtain like this becomes so-called long wool tweed by fulling milling felting then.Here it is because the hair unicorn sheet of holding up relates to (also being undesirable usually) hook company of wool fibre.
Nonwoven fabric constitutes another group spinning plane configuration thing.They can pass through dry type or wet method manufacturing.
When making bondedfibre fabric with damp process staple fibre in water, stir very rarely and by separating screen (Ablagesieb) and moisture from, then chemistry or thermally be combined into nonwoven fabric mutually.Dilution factor high in water is guaranteed from the extremely fiber hook company and the inter coagulation mutually mutually of separate sources with the fibre length of lacking.Can realize the very high uniformity that fiber distributes on the whole like this.But the plane configuration thing that obtains can not bear big mechanical load.
The finite length fiber of the fibre bag for preparing from the manufacturing preliminary stage when making bondedfibre fabric with dry process is by shredding, in case of necessity with the mixed with fibers of other type, in combing equipment, it is carried out " combing ", at this moment form fiber web/fiber pile (Faserflor) along preferred orientations.A plurality of this fibroreticulate layers stack (" piling up ") mutually, at this moment can adjust the preferred orientations of fiber by the motion of the lay in the border, and these layers are transformed into nonwoven fabric perpendicular to the nonwoven fabric plane earth by reinforcement means arbitrarily then.This technology allows high productivity ratio simultaneously in that high fiber placement is inhomogeneity.The mixing of fiber allows in very large range to be complementary with desirable flat fabric performance.In order to improve mechanically stable, for example pill resistance or washability must contact major part the crosspoint chemistry or thermally reinforce into so-called binding site.At this moment improved bending stiffness, and flat fabric has lost drapability (Drapierf higkeit).
When making spunbonded nonwoven, one or more meltings of fusing spin the polymer beads of making in extruder, it are extruded machinery or pneumatically it is stretched and be laid on the lay band by spinning-nozzle.Then with the above-mentioned bondedfibre fabric autofrettage unguyed bondedfibre fabric of mechanical consolidation similarly.
Before several years, also adopting the manufacture method of this plane configuration thing, this plane configuration thing for example is used as the matrix of roof cloth matrix or carpet fiber, they are not had the requirement of textiles drapability usually, and the feature of spunbonded nonwoven is to compare relatively poor uniformity and higher mechanical bearing capacity with the bondedfibre fabric of other type.
Compare with other weaving bondedfibre fabric manufacturing technique, the feature of spunbonded nonwoven equipment is high productivity ratio.This can bring high investment cost, and needs very high repacking time and expense when changing polymer.These factors cause such equipment flexibility to move relatively poorly, and must remain operation.
The common basis of all bondedfibre fabric types is, makes their fiber and piles up mutually by a plurality of (lay in the x-y plane) layer, also must carry out fixed to the bondedfibre fabric of formed mechanical instability in the z direction then.The associated methods of described chemistry or heat causes the decline of drapability.
Compare with other spinning plane configuration thing, bondedfibre fabric has such advantage, and promptly for the bondedfibre fabric plastics, a material or fiber directly are transformed into finished product plane configuration thing.And weaving or when knitting yarn at first must just can be transformed into the spinning plane fabric through plane (configuration piece) forming process of complexity.
Advise that in the prior art monofilament is reeled earlier, then these products is used in the plane configuration thing forming process after it is made.
US-A-3,921,265 and US-A-3,885,279 have illustrated a kind of device that is used for making the method for spinning plane configuration thing and is suitable for this method, wherein yarn is by a plurality of laying device laies.The oriented-laying of yarn has been described here, but the bondedfibre fabric forming process has not been described, it is characterized in that lay to a certain extent by statistical law.In addition not about the explanation of the performance of the yarn of lay.
A kind of device of being made mat or belt by glass fibre or like fibrous has been described in Deutsche Bundespatent 816,215.Wherein in a mechanical conveyor, merge a plurality of long filaments, and become pad as strand twisted back lay on a plane.The lay of thigh is undertaken by the conveying by means of air blast.Difference according to its adjustment can change lay.Do not disclose other details in this part data, particularly thigh is pressed the lay of statistical law.Described strand is retained in the plane configuration thing.
At DE-A-3, a kind of knotted rug that has the second layer base fabric of being made by the endless filament yarn bondedfibre fabric of being made up of the polyester yarn of the mixed and disorderly lay of multilayer has been described in 012,806, yarn is arranged by the parallel construction that intersects.Nonwoven fabric can spin to make or form to have by common traction or unwinding polyester filament and with its common lay and intersect the nonwoven fabric of parallel construction and make by packet type.Do not illustrate that in this part file non-melt spins the use of the fiber of making.
At DE-A-3, illustrated in 630,392 a kind of be used for making be used for depositing water and/or have oleophylic and/or the method for the reinforcing nonwoven fabric of the material of lipophilic characteristic.The formation of nonwoven fabric is spun by direct air blowing and is made (Blasverspinnen) and carry out to a receiving system.
By EP-A-281,865 is known to inorfil, as waterglass fiber or silicate fiber, and the plane configuration thing of the combination of composition.Form nonwoven fabric by directly handle spun fiber with dried lay or wet lay technology.Fiber is by the mutual combination of heat treatment under the temperature more than 50 ℃.Because lower bonding temp must carry out subsequent treatment to spun fiber immediately.
By US-A-5,660,910 known a kind of bondedfibre fabrics with better fracture strength.This bondedfibre fabric also has the reinforcement monofilament of big fiber number except the matrix monofilament.Except the manufacturing of spunbonded nonwoven, also illustrated before to have spun and the monofilament of intermediate storage is processed into bondedfibre fabric.Described monofilament directly is laid on the conveyer belt by an aspirator.The statistics lay of the monofilament of intermediate storage is not disclosed.Owing to adopt the uniformity of the bondedfibre fabric of thick monofilament production also to be restricted.
At DE-A-4, the nonwoven fabric of being made up of monofilament is disclosed in 115,190, described nonwoven fabric has 250g/m
2Big surface density the time have a Mass Distribution very uniformly.In order to make this nonwoven fabric, will resolve into single monofilament by the monofilament (bundle) that various different materials are made by air nozzle, extremely equably it is laid on the face of a motion, then reinforce with known method own.Unexposed bonded fabric with little surface density and homogeneous quality distribution.This just bondedfibre fabric is difficult to make, because on average fall for the easier quilt of the formed inhomogeneities of nonwoven fabric with big surface density and corresponding high unit space fiber number.But only disclose thermoplasticity as fibrous material and spun the material of making.
