Description
The present invention relates to the method that a kind of coating has the former base of filament top layer carpet, the invention still further relates to the coating device of carpet itself with filament top layer and the former base coating of carpet.
Carpet and its manufacture method are very familiar to.Usually carpet can have the top layer of different shaping, and the compressed filament in top layer constitutes, be unordered gather attitude and or mixed entanglement shape, filament clenches mutually herein, this carpet is as the fulling milling felt rug and famous.Other carpet type top layer was drawn scrim material with yarn and was constituted, and yarn is meant fibre bundle, and it can be used as closed coil and makes by scrim material with the traction of tufting process.Carpet is because of making so-called family based carpet based on tufting technology.Coil also can be cut off, and constitutes velvet by the coil segment of cutting off, the time and be reprocessed into fulling milling felt with characteristics with velvet.
Irrelevant with the type of carpet, its top layer will be stood high friction and be trampled load, and good fibre bundle can prevent that by later load single filament being broken away from comes.The assay method that has various criterionization is as the load of trampling with Lisson experimental test one carpet.
For known carpet filament latex set, but use latex to exist defective, latex is incompatible to be recycled, and with latex coated technique energy consumption height, the pure floor space of affiliated production is big.The test of other combining form is not succeeded on filametntary bond quality so far as using thermoplastic material, it does not stretch in conjunction with meeting standardization and trampling-resist-with rub mill-burden requirement.
Thereby task first aspect of the present invention provides a kind of process that applies the former base of carpet, even and abandon filament and still can provide the carpet that bears load with latex bonded method.
By a second aspect of the present invention, task of the present invention is that filament need not latex bonded, still can provide durable firm carpet.
By a third aspect of the present invention, task of the present invention provides the coating device of the former base coating of a cover carpet, and filament needn't can produce the carpet of energy bearing load with latex bonded.
The task of first aspect has solved the process of carpet coating by claim 1, promptly filament can be bonded together at the back side, top layer of carpet coating thermoplastic material.
By method of the present invention the filament on the former base of carpet top layer is combined securely with carpet, this is just meaning filament and is reaching enough degree of adhesions by the thermoplastic material coating, here thermoplastic material is to be coated in the back side, top layer, and this thermoplastic material is bonded in filament on the former base of carpet.Comparing thermoplastic material with latex makes whole carpet recycle easily.The gap nozzle of one definite form that also will be further described below the coating of thermoplastic material is preferably adopted, thermoplastic material is logical to refer to it is based on the adhesive of thermoplastic or based on the formulation material of thermoplastic.
Filament can be applicable to different carpet type through thermoplastic material bonding, especially with coil-or tufted carpet of constituting of velvet, but also comprises the fulling milling felt rug, and it can be made of coil or velvet supatex fabric or Nomex.
Tufted carpet has yarn or the fibre bundle by the scrim material traction, so just in scrim material, the back side all is extruded with the filament part, preferably the filament part with the carpet back side is distracted into coiled type through scrim material, the formation of carpet coil is the back side that the fibril bundle in carpet front is drawn to carpet through scrim material, by a coil it is turned around, with the front of drawing back carpet from the carpet back side through puncture site by scrim material, the fibre bundle at the carpet back side is partly unfixing, thereby it is very sensitive, they pull out very loosening state by scrim material, and each root filament is easily from wherein pulling out.By adding thermoplastic material whole fibre bundles can be cemented on the scrim material at the carpet back side enduringly.Thermoplastic material need be immersed in hollow area just can make carpet become firm.Thermoplastic material also has at least a part to be immersed in the fibre bundle on the other hand; make filament also sticky together; when thermoplastic material immerses the external zones of fibre bundle; the adhesive that soaks into by part forms bonding protective layer to a certain extent like this, and it can strengthen the durability of carpet.The fibre bundle part of coating thermoplastic material forms so-called carpet knot at the carpet back side.
When the fibre bundle at the tufted carpet back side formed coil, its front can have multi-form, the shape that coil is cut off for example, and various types of tufted carpets all are suitable for coating of the present invention.
In other known carpet Implementation Modes as the velvet felt rug, filament is to use mechanical means, and as compression, acupuncture or fulling milling or the together bonded to each other and configuration top layer of method by heating, filament forms mixed entanglement shape or the unordered attitude of gathering.The fulling milling felt is coated with thermoplastic material at the carpet back side and is added on the compressed top layer.On the fulling milling felt rug, also surprisedly see, pass through the coating thermoplastic material with simple method, filament is bonded together, equally also is suitable for the fulling milling felt rug between the fiber of overcompression and thermoplastic material coating, optionally adding a base cloth lining.
