a) Title of the invention

Textile packaging material, in particular for use in heavy duty bags

b) Field of application of the invention

The invention relates to a textile packaging material for use in heavy-duty bags, which must be stackable and suitable for transport and storage of fine-grained materials of a mass of primarily 50 kg and more. Filled goods may contain, for example, cereals, sugar and the like. be a.

c) characteristic the known technical solutions

Known textile packaging materials have a more or less smooth surface, that is, a low surface structure. The associated low coefficient of static friction is in many cases an obstacle to good stackability of the bags.

The known woven sackcloths of outergrains and similar yarns partly have to achieve better stackability rib and Spitzköperbindungen from which results in a more suitable structuring, the amount of which depends only on the thickness or the diameter of the processed Fadenmatarials. Furthermore, bag fabrics made of folie threads (usually polyolefin tapes) produced by the raschel technique are used. With these bag materials, the static friction

coefficients well below the values for fabrics. The known, used for the production of sacks and for packaging stitchbonded also have a relatively smooth surface.

The sacks made from foil threads are difficult to stack. Their storage is often required by repeated stacking increased workload, and the existing storage capacity can only be exploited incomplete. In addition, slipping the bags can easily lead to work accidents.

The mentioned packaging materials have a low trickle density or are made so dense that the air permeability is very low. As a result, the necessary air conditioning when used in the sugar packaging is extremely limited.

d) Object of the invention

The object of the invention is to provide a textlien packaging material available, which has the strength required for heavy-duty bags, their good stackability allows and in addition to high giants density has good air permeability and is producible productively.

e) essence of the invention

Technical object of the invention is the construction of a textile packaging material, which has many pores, but which have a low pore radius, the structure gives a high stability and the surface is structured.

The solution according to the invention provides that a nonwoven web of transversely oriented long staple fibers having a minimum denier of 0.8 tex is sewn tightly by two thread systems, one side of the produced fabric web containing longitudinally or transversely directed ribs of nonwoven thickenings. The thread elements of the second thread system are arranged in the case of transverse ribs to reinforce the structural effect that they are substantially longitudinally between the ribs and substantially transverse in the region of these ribs ·

The ribs can be broken · The fineness of the threads of the second thread system can be at least 7 times the fineness of the first thread system.

The nonwoven web is preferably made of regenerated fibers with Oute character, which interlock well with each other due to their nature, when touching two fabric surfaces during storage of the packaged under pressure ·

Surprisingly, it has been found that the packaging material produced in this way is capable of safely and elastically absorbing high forces which occur when it is used for filling, especially when filling. Also surprisingly, with good air permeability, no trickle losses occur in contrast to almost all others. Packaging materials of this capacity. The rigid upper sewing of the nonwoven web causes the rigid fibers to bulge, which in addition to strongly compressed line - shaped areas also produces linear "puffy" areas which ensure good air permeability · In the case of transverse ribs, these bulky areas are additionally protected by the threads covering them Technology of producing nonwoven sewing fabrics is very efficient ·

With the packaging material according to the invention a high slip force is achieved in the stack, wherein the further sliding forces on the stack are limited, whereby the degradation of the stack is not adversely affected «

Embodiment 1

The textile packaging material consists of a nonwoven of viscose fibers in the outetype, 2 tex, 170 mm fiber length and a first thread system of polyamide silk 10 tex and a second thread system of polyamide silk 94 tex. According to FIG. 1a, the upper surface of the fabric is above the nonwoven fabric 1 Thread elements 2 of the first thread systems, which run as mesh webs substantially in the transverse direction, and the threads 3 of the second thread system, which are stretched in the longitudinal direction · According to FIG. 1b, thread elements 2 'of the first thread system are arranged in the form of meshes in the longitudinal direction on the back side of the fabric ·

On this side there are longitudinal ribs 1 * from the coarse fibers of the web "These ribs bulge up" because in the area of the meshes of the thread elements 2 * the fiber web is strongly compressed line-shaped. The fabric has a static coefficient of friction of 0.9 on the ribbed side, which is taken outwards on the bag.

Embodiment 2

The textile packaging material consists of a non-woven fabric of viscose fibers of the outetype, 2 tex, 170 mm fiber length and two thread traps made of polyamide silk 10 tex. According to Fig. 2a extend on the top of the fabric, the thread elements 4 of the first Fadensysteans as stitch webs substantially in the transverse direction and the thread elements 5 of the second thread system as mesh webs substantially in the longitudinal direction. On this side of the fabric are at a distance of 1.4 ram transverse ribs 6 from the coarse fibers of the web, which are covered by the thread elements 4 and 5 in part. On the back of the fabric the thread elements 4 'and 5 ¹ of the two thread systems wales shaped longitudinally extending as shown in FIG. 2b. Between them and the Fadenelemanten 4 and 5 of the upper side of the fabric is the fleece 6 *. The formation of transverse ribs 6 in contrast to the embodiment 1 is achieved by the significantly lower thread thickness in the second thread system and the inclusion in the stitch formation. The back is relatively smooth. The ribbed side has a coefficient of static friction of about 1.0 and is taken outwardly in use.

Embodiment 3

The textile packaging material consists of a fiber fleece made of viscose fibers, 0.8 tex, 100 mm fiber length and a first thread system of polyamide silk 10 tex and a second thread system of polyaraid silk 94 tex. From the first thread system according to FIG. 3a, thread elements 7 are arranged on the upper side of the fabric as stitches substantially in the transverse direction. The much coarser threads of the second thread system have a relatively large distance from each other. On four threads of the first thread system comes a thread of the second thread system ·

The yarn elements 8 of the second yarn system run essentially in the longitudinal direction, whereas the yarn elements 9 of the second yarn system run essentially in the transverse direction. Threaded elements 7 'of the first thread system are mascheηformig arranged longitudinally in the longitudinal direction, while thread elements 9' of the second thread system at selected locations in addition to the thread elements 7 * of the first thread system lie in a loop.
