Definitions
- this disadvantageous process step of pre-needling can be eliminated by placing the still unconsolidated fleece coming from the spinning system on a rotating screen drum on which the finishing agent is sucked through the fleece in the form of a mist by means of negative pressure and over several suction zones are sucked through the inside of the sieve drum.
- the main disadvantage of this already improved method is that the The nonwoven's uniform weight per unit area is still unsatisfactory, since high production speeds are not possible and that a relatively complicated depositing device with the aid of negative pressure and complicated regulations is required.
- spunbonded nonwovens with good basis weight uniformity can be produced at about twice, in special cases also at higher production speeds compared to known methods.
- speeds of up to about 40 m / min and, in special cases, up to about 60 m / min can be achieved, depending on the nonwoven weight.
- conventional Processes for producing needled spunbonded nonwovens have a maximum production speed of about 20 m / min.
- the two nonwoven surfaces are preferably sealed only to a maximum depth of 0.2 mm.
- the method according to the invention is suitable for producing nonwovens from all thermoplastics suitable for spunbonding technology. It is preferred for the production of spunbonded fabrics from polyolefin threads, such as. B. polyethylene or polypropylene threads, polyamide threads or polyester threads. Polypropylene threads are particularly preferably used, both threads made of polypropylene homopolymers and propylene-ethylene copolymers being possible.
- the basis weights of the nonwovens produced are approximately 30 to 2500 g / m2, preferably approximately 100 to 2000 g / m2.
- the lubricant can by conventional methods such. B. be applied by spraying or by means of impregnation rollers.
- the subsequent needling is carried out on known needling machines, for example as described in DE-PS 30 09 116, where solidification is carried out in one step or in stages up to the desired degree of needling.
- the loose fleece structure was reversibly consolidated, whereby only the fibers located on the fleece surfaces were caught and softened by the temperature influence and by the roller pressure were pressed together, a kind of sintering effect being achieved at the crossing points of the fibers.
- Sufficiently viable surface layers were created on the top and bottom sides of the fleece, which can be redissolved in the later process, the layer thickness being less than 0.1 mm.
- the fleece obtained had the following properties: Grammage (DIN 53 854) 110 g / m2 Basis weight uniformity c V (DIN 53854) 8th % Strip tensile strength (DIN 53 857/2) 780 N / 10 cm Stamp puncture resistance x (DIN 54 307) 1320 N.
- Example 2 Analogously to Example 1, a web with a basis weight of 1000 g / m2 was produced at a belt speed of 3 m / min. The pre-consolidation was carried out at 120 ° C - 125 ° C roller surface temperature and 35 - 40 N / mm line pressure. The thickness of the sealed surface layer was 0.2 mm, at least 90-95% of the fibers remained unconsolidated.
- Example 2 Analogously to Example 1, a fleece with a basis weight of 70 g / m2 was produced at a belt speed of 35 m / min. The pre-consolidation was carried out at 130 - 135 ° C roller surface temperature and 20 - 30 N / mm line pressure. The thickness of the sealed surface layer was 0.05 mm, at least 60% of the fibers remained unconsolidated.
- polyester with an MFI (280 ° C / 2.16 kg) of 40-45 and a relative viscosity of 1.3-1.4 at 280-300 ° C were fibers with a fineness of 2-8 dtex spun and at a production speed of 27 m / min a fleece with a basis weight of 100 g / m2 is produced.
- the pre-consolidation on the calender was carried out at a roller surface temperature of 180 - 190 ° C and 25 - 30 N / mm line pressure.
- Basis weight 100 g / m2 Uniformity of basis weight 8th % Strip tensile strength 680 N / 10 cm Stamp puncture resistance 1140 N.
- Fibers with a fineness of 6-8 dtex were spun from polyamide 6 with a relative viscosity of 2.4-2.5 at 300-310 ° C and a nonwoven with a basis weight at a production speed of 10 m / min of 250 g / m2.
- the pre-consolidation on the calender was carried out at a roller surface temperature of 190 - 200 ° C and 30 - 35 N / mm line pressure.
- fibers with a fineness of 8-12 dtex were spun from polyethylene (HDPE) with an MFI (190 ° C./2.16 kg) of 12-14 at 210-240 ° C. and at a production speed of 25 m / min a fleece with a basis weight of 110 g / m2 is produced.
- the calender was pre-consolidated at a roller surface temperature of 90 - 100 ° C and 25 - 30 N / mm line pressure.
