Definitions
- the invention relates to a multi-layer textile structure comprising two textile upper layers, at least one textile middle layer being arranged between the two upper layers.
- Such flat textile structures are known, for example, from DE 20 2008 016 926 U1 and DE 10 2004 024 134 A1.
- DE 20 2008 016 926 U1 shows a cellulose cloth consisting of a fiber layer
- liquid-absorbing cellulose fibers and a further layer bonded to it on one side, the further layer deviating from the fiber layer in terms of color or color pattern.
- the fibers of the fiber layer are made by partially pressing or compacting the pulp fibers
- Fiber layer forms a middle layer and is arranged between two outer layers.
- the absorbent textile structure shows an absorbent textile structure with high absorption performance for oils, emulsions, chemicals and other water and soil pollutants.
- the absorbent textile structure consists of a composite with a wrapped absorbent core, with an absorbent and storable layer between a thin, permeable, dimensionally stable and lint-free base and cover layer, which is formed from continuous filaments arranged in a tangled position. All layers are connected to one another.
- the invention is based on the object of providing a multilayer textile structure which at the same time has a high cleaning performance with a high water absorption capacity.
- the multilayer textile fabric according to the invention comprises two textile upper layers, with at least one textile middle layer being arranged between the two upper layers, the upper layers comprising microfibers.
- top layers comprise microfibers
- the relatively low porosity reduces the amount of water released through the top layers.
- the top layers comprise microfibers, they have a very good cleaning performance. On the one hand, a good water balance is achieved through the use of microfibres and the associated capillary effects between the fibers. The cleaning liquid stored in the middle layer on the inside of the cloth is very even and with the smallest drops on the surface to be cleaned
- the middle layer preferably forms a water reservoir, so that liquid can be stored in the interior of the multilayer textile structure.
- Knitted fabrics are textile fabrics in which loops made from yarns are looped into other loops. This creates a network of meshes. Knitwear has a high degree of stretchability and elasticity with a voluminous handle at the same time.
- the upper layers and the middle layer can be knitted
- Knitted fabrics are flat structures made from thread systems or fiber systems by stitch formation on a knitting machine. In contrast to knitted goods, the thread or the fibers form superimposed stitches in a knitted fabric. The thread or fibers run vertically and form a wale with the adjacent thread or fibers.
- the advantage of knitted fabrics is their great dimensional stability.
- the top layers and the middle layer can be connected to one another by knitting. This results in a firm connection of the upper layers and the middle layer to one another, so that the upper layers and the middle layer are securely connected to one another.
- the upper layers and the middle layer can be connected to one another by operative connection. This enables the multi-layer textile fabric to be folded on a knitting machine in one go.
- the upper and middle classes are firmly connected to one another.
- the yarn for the at least one middle layer can contain monofilaments.
- Such a yarn preferably has a titer of at least 5 dtex, preferably at least 10 dtex, more preferably at least 25 dtex.
- a relatively thick middle layer with a high porosity is created, which is particularly suitable for absorbing large amounts of water and for giving the multilayered textile structure a minimum thickness.
- the middle layer Due to the rather high porosity, the middle layer also shows a bit
- the multilayer textile structure has a relatively low area weight overall.
- Both top layers preferably form cleaning surfaces.
- the multi-layer textile structure forms a cleaning cloth. Finishing the top layers with microfibres results in a particularly good cleaning performance against greasy soiling. In this respect, a cleaning cloth of this type is particularly suitable for cleaning in unfamiliar households.
- the yarn for the upper layers is preferably designed as a multifilament yarn.
- multifilament yarns In comparison to monofilament yarns, multifilament yarns have a smaller diameter and a lower weight per unit area.
- the yarn for the upper layers can be designed as a staple fiber yarn.
- Staple fiber yarns contain fibers of finite length. This means that different types of fiber can be mixed and natural fibers in particular can be processed.
- the proportion by weight of the microfibers based on the weight of the respective top layer is preferably at least 30% by weight. With such a proportion of microfibers, a particularly high cleaning performance and a particularly low porosity result, so that the multilayer textile structure has a particularly high water storage capacity.
- the titer of the microfibers of the top layers can be less than 1 dtex. Fibers with a titer of less than 1 dtex are considered Microfibers denote and have a high cleaning power, especially with regard to greasy soiling.
- the middle layer can contain microfibers. This is particularly advantageous when a higher water absorption capacity is to be achieved.
- the proportion by weight of the microfibers based on the weight of the middle layer can be at least 10% by weight.
- the top layers can have a three-dimensional relief structure. This can result in a particularly good grip, which is particularly advantageous when used as a cleaning cloth. Furthermore, elevations and depressions can arise in which during cleaning
- the total weight per unit area of the textile fabric can be between 200 g / m 2 and 500 g / m 2 .
- An advantageous total thickness of the textile structure is between 1.5 mm and 5 mm.
- the total weight per unit area and such a total thickness shows particularly good handling and good cleaning performance, as well as high
- 1 shows the multilayer textile structure in a side view
- 2 shows the multilayer textile structure in detail.
- the figures show a multilayer textile structure 1 in the form of a
- the multi-layer textile structure 1 comprises two textile upper layers 2, 3 and a textile middle layer 4 arranged between the two upper layers 2, 3.
- the upper layers 2, 3 form the cleaning surfaces of the cleaning cloth and the middle layer 4 forms a water reservoir.
- the top layers 2, 3 contain microfibers in the form of multifilament yarns with a titer of 0.15 dtex.
- An alternative multilayer textile fabric includes in the
- Upper layers 2, 3 also yarns with a denier of 1.5 dtex.
- the proportion of microfibers based on the weight of the respective top layer 2, 3 is in each case 60% by weight.
- the middle layer 4 comprises yarns made of monofilaments with a titer of 30 dtex.
- the middle layer further comprises microfibers in the form of
- the proportion of multifilament yarns based on the weight of the middle layer 4 is between 15% by weight and 50% by weight. In the present exemplary embodiment, the proportion is
- Multifilament yarns based on the weight of the middle layer 4 20% by weight.
- the upper layers 2, 3 and the middle layer 4 are designed as knitted fabrics in the form of a knitted fabric.
- the top layers 2, 3 and the middle layer 4 are connected to one another by stitching in the form of an operative connection.
- the upper classes are 2, 3 and the
- Middle layer 4 positively and firmly connected to one another and form a unit.
- the total weight per unit area of the textile structure 1 is between 100 g / m 2 and 400 g / m 2 , preferably between 150 g / m 2 and 300 g / m 2 , further preferably between 180 g / m 2 and 250 g / m 2 .
- the total basis weight is 240 g / m 2 , the
- the total thickness of the textile structure 1 is 3.5 mm.
- the multilayer textile structure 1 according to the invention is designed to accommodate up to 500% by weight of its own weight (dry weight). If the amount of water bound in the textile structure is reduced to 200% by weight based on the dry weight of the textile structure by means of a wringing process, the dense structure results in the
- Upper layers 2, 3 have a water release of less than or equal to 1.5 g / m 2 , preferably 1 g / m 2 .
