Definitions
- This invention relates to a new needled felt fiooring and to a method of preparing the same. More particularly, this invention relates to a needled felt flooring having a downy surface. This invention is particularly directed to a method of forming such a needled felt flooring employing strip material disposed between two layers of needled material, the fibers from one layer passing through said strip material and mingling amongst the fibers from another layer.
- Felt fiooring has heretofore been provided. These felt fioorings have comprised sheets of fibers, which sheets have been needled and thereafter been impregnated with a binder. However, the fioorings which have heretofore been provided have been rough and hard. It has become desirable therefore, to provide a fiooring material which is not rough and hard and which has a downy surface. Moreover, it has become desirable to provide a needled felt flooring of improved resiliency, less resistant to being walked upon. The natural is to provide a flooring which is less tiring to the feet.
- this invention contemplates a needled felt flooring comprising a layer of strip material disposed over a fibrous needled sheet, said strip material having a layer of a second fibrous sheet disposed thereover the fibers of which pass through said strip material and through at least a portion of the needled fibrous sheet disposed therebeneath.
- the needled fibrous sheets of the present invention are non-woven fibrous sheets and can be made of any suitable natural or synthetic fiber.
- This invention further contemplates a method of preparing needled felt flooring which comprises the steps of:
- the fibers themselves, are generally short staple length fibers having a staple length between 40 and mm., preferably between 60 and 90 mm.
- the thickness of the sheet will be between 1 and 5 mm., preferably between 2 and 4 mm.
- the fibers of the sheets can be of the following: wool, cotton, rayon, nylon 6, nylon 6/6, polyester, especially polyesters derived from terephthalic acid, or its isomers or their derivatives, polyacrylonitrle, polyolefin especially polyalphaolefin and most preferably polypropylene.
- the strip material employed in the present invention is preferably made of a woven material the fibers of which can be of any of the above-mentioned, preferably polypropylene.
- the strip material will have a thickness between 0.05 and 0.2 mm., preferably between 0.10 and 0.15 mm. It can be woven in any one of the standard weaves such as the plain weave shown in FIG. 2 below.
- the felt flooring is prepared by impregnating the layers of fibrous material after the fibers of the second needled layer have passed through the strip material to be disposed among the fibers of the first or preneedled fibrous material and/or after raising and shearing the laminate.
- impregnating agents can be used when the same are in a liquid mating; butadiene-nitrileacrylic, styrolene-butadiene, polyacrylonitrle, polyvinyl acetate, gum elastic.
- binders can be used in a construction between 20 and 40 weight percent, preferably between 25 and 35 weight percent.
- Liquid solvents or diluents which can be used together with such binders include: water, alcohol.
- the binder is applied in the form of liquid dispersion wherein there is formed a foam which contains between 0.42 and 0.51 parts per liquid per part of air, preferably between 0.46 and 0.48 parts of liquid per part of air.
- the impregnating is carried out by disposing the impregnating agent on the unraised side of the layers of the felt fiooring being prepared.
- the so-impregnated fibrous material passes through a pair of rollers.
- Suitably metallic rollers which are spaced about the spacing of these rollers is dependent to some extent upon the width of the fiooring being prepared. Generally speaking, they are between and 15 mm. apart.
- FIG. 1 is a side elevation of a preneedled fibrous sheet employed as a first layer pursuant to the present invention.
- FIG. 2 is an enlarged plan view of a woven fibrous strip material preferably composed of a 3 mm. wide polypropylene strips, tightly interlaced to define a compact structure. (Reference is made to Testil Industry 7l, 1, 1969, p. 17.)
- FIG. 3 shows a side elevation of a double fibrous structure made by disposing the woven strip material of FIG. 2 over the preneedled non-woven sheet material of FIG. 1.
- FIG. 4 shows a side elevation after a non-woven sheet material is disposed over the woven strip material of FIG. 2, this latter layer being the one which is subsequently needled to form small fibrous tufts which are drawn through the strip material to mingle with the fibers of the preneedled layer, itself the subject of FIG. 5.
- FIG. 6 shows the barbs of the needles which have to be filled completely with fibers of the uppermost nonwoven material, since, otherwise, the strip fabric is damaged.
- FIG. 7 shows the filling of the barbs with fibers of the uppermost non-woven layer so that the sharp edges of the barbs do not come in contact with the strips.
- FIG. 8 is a side elevation showing the disposition of fibers of the uppermost layer which is preneedled being disposed through the strip material of FIG. 1.
- FIG. 9 is a ow scheme of the process by which the needled felt fiooring of the present invention is prepared.
- a fabric of non-woven fibers 2 is passed through a needling frame 4 through a pair of rollers 6, beneath a guide roller 8 and a second pair of rollers 10.
- a second fabric of woven fibers is disposed thereover, that fabric being identified by reference numeral 12.
- a second layer 14 of non-woven fibers emanating from a carding machine 16 is disposed over fabric 12 and needled in a second needling frame 20.
- the composite of the layers is withdrawn and taken up on package 24. It will be noticed that the fabric 14 is thicker than fabric 2 so that the resultant production has a pile surface.
- the needling which takes place in needling frame is such that the needles pass through fabric 14 but their barbs do not touch fabric 12. This is important because if they do touch fabric 12 the fibers from fabric 12 are apt to be disposed amongst the fibers 22. If they are of a different color a recoloring operation wtih ensuing cost will be necessary.
- the composite of the fibers is subsequently withdrawn from package 24 and passes through guide rollers 26, through a raising roller 28, and a second raising roller 30 with the assistance of guidance rollers 32, 34, 36 and 38. Thereafter they may be cut through use of a cutter at 40 whereby the raised pile is cut off to, for instance, half of its initial dimension.
- the fabric continues travelling through rollers 42 and 44 and is taken up on package 46.
- the nip of the opposed rollers such as rollers 50 and 52.
- the unraised side of the felt flooring is imbinder, and under liquid diluent formed into a foamy dispersion.
- the nip of the rollers can measure 3 mm. at the narrowest point. The impregnant travels downwardly 4 into the felt fiooring until it reaches the strip material or fabric 12.
- the felt fiooring is taken up on a conveyor 54 and passes into a drying chamber 56 which it is dried. After, it is wound upon package 60 in its finished state.
- the triple fiber structure was subsequently unwound from the roller and passed through a pair of raising rollers where the fibers from the uppermost layer now disposed throughout the middle layer were raised.
- the resulting pile was cut to half of its original dimension and taken up on a second roller. It was thereafter taken off of the roller and passed through an impregnation step by passing it through the nip of opposed metallic rollers disposed a distance of 3 mm. apart. Here they were treated with a 45 percent liquid dispersion of butadiene-nitrile-acrylic in a liquid made into the form of a foam by passing it through an Oakes mixer. The foam so obtained had about three parts of liquid per part of air.
- the amount of binder or impregnant added to the side opposite the pile was regulated so that the binder penetrated only down to the stripmaterial or middle layer and the downy side remained free of binder.
- the entire structure was then passed through a drier maintained at a temperature of about C. wherein the binder was dried. The material was then taken up on a third roller in finished form.
- Needled felt fiooring comprising a layer of strip material disposed over a fibrous needled sheet, Said strip vmaterial having a layer of a second fibrous sheet disposed thereover, the fibers of which pass through said strip material and the needled fibrous sheet disposed therebeneath, forming a pile surface of signle fibers of equal length.
- a needled felt fiooring according to Claim 2 wherein said impregnant is a butadiene-nitrile-acrylic impregnant.
- a needled felt fiooring according to Claim 2 wherein the layer of strip material is composed of polypropylene fibers having a denier of 17 and a weight in sheet form of 300 g./m.2.
- a method of preparing a needled felt flooring which comprises the steps of:
- said binder comprises an impregnant of butadiene-nitrile-acrylic ⁇ 9.
- a felt ooring according to Claim 2 wherein said 6 brous needled sheet and said second fibrous sheet are nonwoven sheets, said strip material is a woven sheet and said second ibrous sheet weights more than said fibrous needled sheet.
