Abstract
ABSTRACT
A fleece laminate includes a filler fleece and a thread reinforced fleece and has a total thickness of more than 2 mm. The filler fleece has a low specific volume, a raw density of below 0.025 g/cm3 and a thickness of 1.6 to 60 mm. The thread reinforced fleece is composed of 10 to 60 g/m2 fleece material having a raw density above 0.035 g/cm3 and 3 to 100 g/m2 of a thread reinforcement. The laminate has a high strength in the warp direction. A fleece laminate of large volume is achieved without the reduction in volume and high density observed in conventional reinforced filler fleeces.

Description
2~7~7~
Fleece Laminate Havin~ Hi~h SDec~fic Volume And Good Stren~th This disclosure relates to fleeces and more particularly to thread reinforced fleeces.
In the padding art, fleeces with thread reinforcement in ~he warp direction, in warpJwoof (weft) or in warp/short woof direction have prevailed over the last years. Padding fleeces with thread reinforcement in warp/woof direction are disclosed in EP-A 0 119 754.
The required technology i3 described in the publication CHEMIEFASERN/TEXTILINDUSTRIE 39, 91, (Msi 19~9), 5124. ~owever, neither of these publications refer to laminates which consls~ of a filler fleece wlthout thread reinforcement having a raw density below 0.025 g/cm3 and of a thread reinforced fleece having a raw density (without reinforcement) of above 0.035 g/cm3.
Warp reinforced fleeces have a wider area of application than regular fleeces due to their greater strength and smaller stretch in the direction of the reinforcement. This is important, for Qxample, for waist band paddings where great strength and short s~retch in longitudinal direction of the waist band arP required. The list or edging of wool coats is a similar area where the use of a fleece is especially advantageou~ (little reclinching, relatively high volume at low weight, etc.). However, the strength of a regular fleece in direction of the border or edge is insufficient and only the reinforcement with warp threads permits the use of a Pleece in this application. Fleece reinforcements in warp/short woof and warp/woof direction are also of interest for other applications. The increased strength in one direction of a warp reinforced fleece is primarily of interest in the placket art where the fleece is used as placket reinforcement. When such materials are used as filler fleece-q for anoracs, winter clothing, etc... they are distinguished from simple non-reinforced filler fleece~ by their technical advantage~.
Generally, when relnforcement in warp, warp/woof9 or warp/short woof direction is used, a striking reduction is observed in the filler fleece volume, resulting in increased density. This has two aggravating disadvantages:
~7~76~
1. As a consequence of the reduc~ion in volume, more fibers are required to produce the same fleece volume (significant increase in costs).
2. Thick filler fleeces of more than 1 cm thicXness can not be warp S reinforced, since this is not pos~ible with conventional machines.It is now an ob~ect of the present disclosure to describe a fleece laminate made of a filler fleece and a thread reinforced fleece which laminate has a total thickness of more ~han 2 mm. It is another object to disclose a thread reinforced laminate of high strength in warp direction or in both directions without the volume reduction prevlously observed with conventional reinforced filler fleeces. It is yet another ob~ect to disclose a laminate whereon this large volume is achieved with as few inserted reinforcement threads as possible.
These ob~ects are achieved in a laminate comprising a filler fleece with a thread reinforced fleece laminated to it. The laminate has a total thickness of more than 2 mm, in which the upper limit can be selected according to the requirements of the user. The filler fleece has a low specific volume, a raw density below 0.025 g/cm3 and a thickness above 0.6 ~m, so that the upper limit which can still be processed will be about 60 mm. The filler fleece includes no thread reinforcement. The thread reinforced fleece is a combination of a 10 to 60 g/m2 fleece having a raw density above 0.035 g/cm3 and 3 to 100 g/m2 thread reinforcement. The thread relnforcement may be positioned inside or on the surface of the lamlnate.
Since it is one of the ob~ects to achleve a high volume fleece, the laminating must be carried out in such a way that preferably there is no volume reduction. For this purpose, the layers of the laminate should be laminated in the heating zone not under pressure but with an intermediate gap. A laminate produced in this way can be used without adhesive, but may be provided with an adhesive applied in point form on the side of the thread reinforced fleece if the lamlnate is to be used as fixing padding. The laminating must be carried out in such a way that as much volume as poasible is maintained. To achieve this, the thread reinforced fleece may be provided on at least one surface with a hot melt adhesive applied in point form, with a continuously applied adhesive powder, or with an air permeable adhesive net. In all these 2~7'~7~8 cases, a continuous press may be used for the lamlnating process and the solidification must occur with as little pressure as possible.
High frequency vibrating or hot melt needles which penetrate the thin reinforced fleece up to the surface of the filler fleece may also be used. In these latter cases, the fibers used for the filler fleece and the thread reinforced fleece must be thermoplastlc. Materials of this type may be used especially in paddlng for clothlng. They may also be used for the filling of bedding material and advantageously combine strength and volume.
The use of charmeuse as a covering for filler fleeces to improve fiber migration is already known in the padding art. However, the laminate described herein has the following advantages over that combination:
1. The strength in direction of the thread reinforcement is greater than with the use of charmeuse; and 2. The fiber migration of an open charmeuse covering relatively to the covered filler fleeces after a series of tests is only marginally improvedl while the thread reinforced fleece provides much better protection because no holes are present.
To achieve a combination of softness, strength and minimal fiber migration, it may be desired in some cases to cover a voluminous fleece on both sides with a thread reinforced thin fleece material or on one side with a thread reinforced and on the other side with a non-reinforced fleece. ~owever, in each of these cases, a novel laminate is achieved which includes a filler fleece without thread reinforcement and a thread reinforced fleece. Thus the intended ob~ects are achieved with these laminates and the volume of the laminate is maintained while the strength distribution is anisotropic.
Example A filler fleece was made as ~ollows:
100 g/m2 polyester fibers 3.3 dtex were laid down under transverse carding and sprayed on both sides with 8 g/m2 of a solid polyacrylate binder with methylol acrylamide groups, dried, and the binder coalesced at 160C. This fleece was rolled and had a thickness of about 13 mm, 35 measured according to DIN 53855, part 2.
A thread reinforced fleece was manufactured as follows:
2(37~7~i8 25 g~m2 of a 100% nylon 6-fleece was lald down under transverse carding and solidifi~d to a fleece by using a point weld calender at 200C. This fleece was rolled and subsequently covered with 12 g/m2 of a copolyester hot melt adhesive applied in point form. The fleece was reinforced by shootlng through it kno~n polyester warp threads 50f22 at a density of 3.6/cm. The resulting warp reinforced fleece was printed on one side with a copolyester hot melt adhesive of 12 g/m2 applied in point form.
These two fleece materials were laminated in a ~eyer continuous press in such a way that ~he adhesive side of the thread reinforced fleece came to lie against the fi$1er fleece. The temperature on the side of the thread reinforced fleece was 160C and on the filler fleece side 180C. The speed of the laminate in the press was 10 meters per minute. The heating zone had a length of 2.5 m. The layers were not laminated under pressure but with an intermediate gap to maintain the combined volume of the layers throughout the fixation process as high as possible.
The single attached drawing shows a cross-section through a laminate of the principal construction disclosed herein, wherein the base fleece 1 has a warp reinforcement 2 and i9 laminated with the filler fleece 4 by way of an adhesive 3 applied in point form.
