Definitions

  • the invention relates to crepe papers, processes for their production and their use.
  • the fine pleating across the machine equipment results in the great elasticity of the crepe paper, which is used in the sanitary and hygiene sectors for the manufacture of handkerchiefs, towels, serviettes, diapers and toilet paper, but also for the production of adhesive and masking tapes.
  • the crepe papers are usually Made from high-quality cellulose but also from (un) bleached ground wood together with common additives while maintaining the desired thickness and the intended basis weight.
  • the wet crepe paper is pressed by a press at high pressure onto the crepe cylinder, from which it is then removed with a scraper at a dry content of approx. 40%.
  • the speed differences to the following paper machine parts e.g. transfer device and drying cylinder
  • Such a method has long been known and e.g. in US-A-1 772 185 and US-A-2 940 591.
  • the scrapers usually used in accordance with the above method have a grinding angle which is in the range from 20 ° to 90 °. Furthermore, the height of the scraping edge is 0.2 to 0.4 mm.
  • the angle between the tangent and the scraper at the point of contact of the scraper with the crepe cylinder is 10 ° to 30 ° in the usual method.
  • the above design of the scraper and the angle of attack cause the paper to be blocked and compressed when scraped off, resulting in the typical "crepe mountains” and "crepe valleys".
  • crepe papers are produced which have a significantly increased elongation compared to the papers taken off directly from the paper machine.
  • these crepe papers have a low smoothness, which means that the adhesive application is very high in the production of adhesive tapes in order to obtain sufficient adhesive strength.
  • the low smoothness of the crepe paper means that the fingers and the skin are often affected during use.
  • the poor smoothness of the paper leads to unsatisfactory printability.
  • EP-A-0 213 596 comprises a crepe paper made from a substrate with a fine crepe pattern which has been smoothed by calendering.
  • the substrate is saturated with a soft, stretchable polymer, resulting in a paper with an elongation of 15 to 25% and a Sheffield smoothness in the range of 20 to 250.
  • the basis weight of the above substrate is in the range of 30 to 75 g / m 2 .
  • the object of the present invention is to create crepe papers which, in addition to being highly stretchable, have a high degree of smoothness.
  • Another object of the invention is to provide a method with which crepe papers with the above properties can be produced, additional process steps or addition of further chemicals to the paper pulp should be prevented as far as possible.
  • the above task with regard to paper properties can be achieved by using a crepe paper with a thickness (DIN 53105) of 0.07 to 0.18 mm, a mass per unit area (DIN 53104) of 25 to 80 g / m 2 and an elongation at break (DIN 53112) of 10 to 16% and a Bekk smoothness (DIN 53107) of 2.5 to 6 seconds on the sieve side and from 1.0 to 3.0 seconds on the top can be solved, this raw crepe paper can be obtained by using the paper web running the crepe cylinder with a scraper with a grinding angle of 20 ° to 60 ° and a crepe scraper edge of 0.01 to 0.02 mm height, the scraper being set at an angle of 35 ° to 45 ° with respect to the tangent to the crepe cylinder , decreases, leads over the surface of the scraper to a transfer device and then onto a drying cylinder.
  • this raw crepe paper can be obtained by using the paper web running the crepe cylinder with a scraper
  • the raw crepe paper has a Bekk smoothness of 3 to 6 seconds, in particular 4 to 6 seconds, and on the top side 1.2 to 3 seconds, in particular 2 to 3 seconds.
  • the mass per unit area (DIN 53104) of the crepe paper is preferably 30 to 60 g / m 2 , and the Breaking strength (dry, according to DIN 53112) advantageously has values in the longitudinal direction of 26 to 50 Newtons / 15 mm and in the transverse direction of 12 to 25 Newtons / 15 mm.
  • Another special version of the raw crepe paper is characterized in that the tightness according to Gurley is 6 to 12 s.
  • a thickness DIN 53105
  • Special configurations of the impregnated crepe paper are characterized in that the breaking strength (dry, according to AFERA 4004) in the longitudinal direction 40 to 120 N / 15 mm, preferably 40-90 N / 15 mm, and in the transverse direction 15 to 60 N / 15 mm, preferably 15-40 N / 15 mm.
  • the impregnation of the crepe paper is preferably based on aqueous dispersions based on styrene butadiene, polyvinyl acetate, acrylate or acrylonitrile or mixtures of these with an application amount of 10 to 40 g / m 2 .
  • a "release coat” is applied to the top of the impregnated paper, which preferably contains an aqueous dispersion based on acrylate, polyvinyl acetate, long-chain fatty acid and / or fatty alcohol derivatives, paraffins or silicone compounds or mixtures thereof in an advantageous amount of 2 to 10 g / m 2 .
  • a primer is applied to the sieve side, which preferably consists of a dispersion based on natural latex, acrylonitrile, styrene butadiene or acrylate or mixtures of these in an amount of 2 to 5 g / m 2 exists.
  • impregnated papers are also included which have a "release coat” on the top and a primer on the screen side.
  • the "release coat” means that the adhesive tape can be unwound again from the roll without sticking to the top of the underlying roll tape.
  • the primer requires the adhesive to adhere well to the screen side.
  • the crepe base papers and refined crepe papers according to the invention can be produced by a method in which the paper web guided on the crepe cylinder is lifted off with a scraper, passed over the surface of the scraper to a transfer device and from there to the drying cylinders, and optionally impregnated and coated, which characterized in that the grinding angle of the scraper is 20 ° to 60 °, the scraper edge has a height of 0.01 to 0.02 mm, and the angle between the tangent and the scraper at the point of contact of the scraper with the crepe cylinder 35 ° to Is 45 °.
  • the above method is carried out so that the speed of the Transfer device compared to that of the creping cylinder is delayed by 15 to 20%.
  • the scraper material is also preferably made of stainless steel.
  • the impregnation can take place in an immersion bath, after which it is squeezed off with rollers.
  • the "release coat” and primer coating is generally carried out using an air brush, a "Mayer Bar”, a “Speed Sizer”, a roller doctor blade, an anilox roller or a “blade coater”.
  • the invention further includes the use of the crepe papers according to the invention for the production of adhesive and masking tapes.
  • crepe papers according to the invention can also be used for the production of printed labels for the marking of shaped articles.
  • the crepe device used according to the invention for producing the crepe paper is shown in FIG. 1.
  • the scraper (2) which is provided with a cover sheet (3), bears against the crepe cylinder (1).
  • the scraper is connected to the scraper holder (4), which in turn is attached to the scraper bar (5).
  • the design of the scraper is illustrated in Figure 2.
  • the front of the scraper has a grinding surface (6) and a scraping edge (7) which, according to the present invention, have a special grinding angle or a defined height.
  • FIGS. 3a, 3b, 4a and 4b the Bekk smoothness of a finished crepe paper (0) according to the present invention is compared with the smoothness of commercially available products (I) to (VII).
  • the representations show the superiority of the crepe papers according to the invention in terms of smoothness and at the same time high elongation, this superiority being particularly evident on the wire side.
  • the crepe paper according to the invention was impregnated with an aqueous dispersion based on styrene butadiene in an amount of 15 g / m 2 . Furthermore, there was a "release coat" on the top based on an aqueous dispersion of acrylate and fatty alcohol derivatives in an application quantity of 4 g / m 2 .
  • a primer was applied to the sieve side in an amount of 2 g / m 2 , which was composed of an aqueous dispersion of natural latex, acrylonitrile and styrene butadiene.
  • the base paper used corresponded to that of the following example.
  • a paper mass formed on a paper machine in the usual way from half-bleached sulfate pulp was passed onto a crepe cylinder and removed from there by means of a scraper.
  • This scraper had a grinding angle of 41 °, a scraping edge with a height of 0.02 mm and was set at an angle of 6 ° with respect to the horizontal on the cylinder at the point of contact.
  • the speed difference between the creping cylinder and the subsequent transfer device was 18%, i.e. the transfer device moved relative to the cylinder with a delay of 18%.
  • the speed of the drying cylinder following the transfer device and the paper rewinder were increased again compared to the transfer device.
  • the speed deceleration between the crepe cylinder and the first drying cylinder was only 12.5% and between the crepe cylinder and the paper rewinder was 9.5%.
  • the crepe paper produced by the method according to the invention has not only a high elongation but also a high smoothness. This can greatly reduce the application of adhesive, particularly on the screen side of the paper, in the production of adhesive tapes and masking tapes. In order to achieve the same adhesive strength as with conventional crepe papers, at least 30% adhesive can be saved. As a result, the manufacturing costs for the adhesive tapes are greatly reduced and the productivity of the manufacturing process increases significantly.
  • the significantly higher smoothness compared to normal crepe paper also means that the fingers and skin of the user are better protected when using the crepe paper.
  • the masking tapes adhere better to one another.
  • the high smoothness, combined with a smaller application amount of adhesive and thus a smaller thickness of the adhesive tape also means that sharp lacquered edges can be produced at the junction between coated and covered areas with adhesive tape.
  • the crepe papers according to the invention can thus advantageously be used as labels for even complicated shaped articles.
