Definitions
- the invention relates to a system and a method for the consolidation and structuring of fibers into a nonwoven according to the preamble of claims 1 and 13.
- the object of the present invention is to provide a plant and a method of the above-mentioned type, by which fibers can be sufficiently solidified and structured.
- the plant according to the invention for the consolidation and structuring of fibers comprises a first and a second circulating belt, which are used for Solidification and structuring of fibers are arranged at least partially parallel to a web and thus form a Strukturier Scheme.
- At least one band is formed as a counter-band with a plurality of patterning openings and arranged within the counter-band in the structuring at least one water beam for hydroentanglement of the fibers.
- the invention is characterized in that the structuring region has a length of at least 0.2 m and the opposite band has micro-openings between the pattern-giving openings.
- the counter-band between the patterning openings has 3 to 100 micro-openings per square centimeter in a random or regular arrangement. This results in a sufficient strength of the web in both directions.
- the micro-openings may have a hydraulic diameter of 0.2 to 2 mm, preferably from 0.2 to 0.4 mm. With a smaller hydraulic diameter, the effect of the water jets has turned out to be too low. At a diameter greater than 2 mm, the micro-apertures act like a pattern. Especially with fibers with a length of 10 to 40 mm has been found that these are repeatedly solidified points.
- the at least one water bar is operated at a pressure of 30 to 80 bar, preferably 60 bar. This is significantly lower than the known hydroentanglement with 100 to 400 bar for solidification of the fibers on a Spunlacetrommel with a raised structural shell. Surprisingly, a more uniform and higher solidification in the machine direction (MD) and in the transverse direction (CD) has resulted in this preferred printing range.
- the structuring region can be preceded and / or followed by at least one further water bar in the transport direction, which is operated at a pressure of 10 to 25 bar and solidifies the non-structured upper side of the nonwoven.
- At least one further water bar which is operated at a pressure of 10 to 60 bar, preferably 15 to 30 bar, and solidifies the underside of the nonwoven can be arranged downstream of the structuring region in the transport direction.
- the structuring region is inclined by 1 ° to 10 ° in the transport direction. This supports the removal of water from, for example, wet-laid fibers.
- a further improvement results from the fact that a moistening device, which ensures a first stabilization of the fibers, is arranged in front of the water beam or bars within the structuring region.
- the method according to the invention for consolidating and structuring fibers into a nonwoven fabric is carried out with a first and a second circulating band, which are arranged at least partially in parallel and thus form a structuring region, wherein at least one band is designed as a counterstrip having a multiplicity of patterning openings, between which micro-openings are arranged, wherein the fleece structured by water jets in the region of the patterning openings and in the region of the micro-openings on a length of at least 0.2 m chambered and solidified selectively.
- the patterning area of about 0.2 m in length with the parallel tape guide ensures a sharp image of filigree patterns in the product.
- a fleece is patterned with a pattern-giving surface, but selectively solidified between the patterns, which due to the quilt effect creates a very fluffy product that can be used as cotton pad, wipe or as a cosmetic product (flushable wipe).
- the invention also relates to a method for solidifying and structuring cotton pads, for example of cotton with a weight of 100-250 g / m 2 .
- the invention also relates to a process for consolidating and structuring nonwovens of staple fibers or filaments such as viscose, polyester, polypropylene, polyamide or lyocell having a weight of 30-300 g / m 2 .
- the invention also relates to a process for solidifying and structuring wetlaid nonwovens from natural fibers such as cellulose, or from synthetic fibers such as polyester, or from manmade fibers such as viscose or lyocell, each exclusively with 100% fiber content or alternatively from mixtures of above-mentioned fibers, for all the aforementioned wet-laid nonwovens having a weight of 30-120 g / m 2 , preferably 45-70 g / m 2 , when used as a wipe preferably with a weight of 30-100 g / m 2 .
