Definitions
- the invention relates to a thermally bonded nonwoven fabric having improved thermal and chemical stability.
- the invention further relates to a use of this nonwoven fabric.
- the document EP 0340 982 B1 discloses melt-bondable fibers and nonwovens made therefrom.
- the melt-bondable fibers are bicomponent fibers consisting of a first at least partially crystalline polymer component and a second component adhering to the surface of the first component comprising a compatible blend of polymers comprising at least one amorphous polymer and at least one at least partially crystalline polymer.
- the melting temperature of the second component should be at least 30 ° C below the first component, but at least equal to or greater than 13O 0 C.
- the weight ratio of the amorphous polymer of the second component to the at least partially crystalline polymer of the second component in the range of 15: 85 to 90: 10 and be sized so that the bonding of the bicomponent fibers is prevented with a similar bicomponent fiber and that the first component of the core and the second component of the shell in the form of a sheath Core configuration forms spun bicomponent fiber.
- This bicomponent fiber is blended with conventional polyester fibers and thermally bonded to a nonwoven fabric which is made into a nonwoven web by application of abrasive particles.
- heat-binding conjugate fibers which have a sheath-core configuration and whose core consists of a polyester containing polyethylene terephthalate (PET) as the main component and the sheath of a copolymerized polyester or a side-by-side Conjugate fiber is made, which consists of a polyethylene terephthalate and a copolymerized polyester.
- the copolymerized polyester is the lower melting component and contains butylene terephthalate units and butylene isophthalate units as repeating structural units.
- a nonwoven fabric made from these bicomponent fibers is said to have excellent thermal resistance and fatigue resistance to compressive loads, so it can be used as an alternative material to polyurethane upholstery, especially in the automotive field.
- thermally bonded nonwovens from a mixture of undrawn and stretched PET fibers.
- binding under heat and pressure in a calender is necessary.
- the binding capacity of the unstretched, amorphous PET fibers is not based on a melting process, but on the crystallization process of PET, which starts above 90 0 C, if there are still crystallizable parts.
- Such nonwoven fabrics have a high meet chemical and thermal stability.
- the manufacturing process allows low flexibility. For example, it is not possible with undrawn PET fibers to activate their binding ability several times, since this is at an irreversible below the melting temperature process.
- the object of the invention has been found to provide a thermally bonded nonwoven fabric which shows improved properties in terms of its thermal stability, in particular the tendency to shrink of the resulting nonwoven fabrics.
- thermoplastic bonded nonwoven fabric containing a low-shrinkage core-sheath bicomponent fiber.
- the low-shrinkage core-sheath bicomponent fiber consists of a crystalline polyester core and a crystalline polyester coating which melts at least 10 ° C., and has a hot-air shrinkage at 170 ° C. of less than 10%, preferably less than 5%.
- a corresponding nonwoven fabric has a thermal towerä ⁇ dtechnik (shrinkage and Bausch) of less than 2% at temperature loads of 150 0 C (1 h).
- crystalline is understood as meaning a polyester polymer which has a melting enthalpy (DSC) of> 40 Joule / g and whose width of the melt peak (DSC) preferably precipitates at ⁇ 40 ° C. at 10 ° C./min.
- the sheath of the low-shrinkage bicomponent fiber consists of a homogeneous polyester polymer prepared from a monomer pair, which is formed to greater than 95% only from a polymer pair. In the case of the polyester described in the claims, this means that the polymer consists of> 95% of a single dicarboxylic acid and a single dialcohol.
- the mass ratio of core and cladding component is typically 50:50, but may vary between 90:10 and 10:90 for specific applications.
- the sheath of the low-shrinkage core-sheath bicomponent fiber consists of polybutylene terephthalate (PBT), poly-trimethylene terephthalate (PTT) or polyethylene terephthalate (PET).
- PBT polybutylene terephthalate
- PTT poly-trimethylene terephthalate
- PET polyethylene terephthalate
- nonwoven fabric wherein the core of the low shrink core-sheath bicomponent fiber is polyethylene terephthalate or polyethylene naphthalate (PEN).
- PEN polyethylene naphthalate
- the nonwoven fabric according to the invention may be dependent on the respective
- the nonwoven fabric according to the invention preferably consists of low-shrink core-sheath bicomponent fibers with a titre in the range between 0.1 and 15 dtex.
- the nonwoven fabric according to the invention has a basis weight between 20 and 500 g / m 2 .
- the nonwoven fabric according to the invention reaches at a Basis weight of eg 150-190g / m 2 a bending stiffness determined according to ISO 2493 transverse to the machine direction of greater than 1 Nmm.
- the method of making the thermally bonded nonwoven web is to lay the fibers into a nonwoven web, thermally bond and, if necessary, compact immediately thereafter.
- the fibers of the nonwoven fabric according to the invention dwell in a thermofusion oven, which enables a uniform temperature control of the binder fibers.
- This compression is preferably carried out immediately after the binding process in the dryer with still hot fibers.
- the structure of the fibers also allows subsequent thermal treatments, since the binding process can be activated several times.
- the resulting thermally bonded nonwoven fabrics have shrinkage and bulk values in the range of ⁇ 2%, preferably ⁇ 1%.
- the nonwoven fabrics according to the invention are suitable as a liquid filter medium, membrane support web, gas filter medium, battery separator or nonwoven fabric for the surface of composites due to their high thermal stability, their low shrinkage tendency and their chemical aging stability. This is especially true for use as an oil filter medium for use in automotive engines.
- the invention will be explained in more detail with reference to FIGS. These show:
- Figure 1 is a diagram in which the maximum tensile forces of the nonwovens A and B are as index after storage in air and oil based on the respective new state (DIN 53508 and DIN 53521).
- Fig. 2 is a diagram in which the maximum tensile force extension of the nonwovens A and B after storage at 150 0 C in air and oil are based on the respective new condition (DIN 53508 and DIN 53521);
- Fig. 3 is a diagram in which the maximum tensile forces of the nonwovens A and B are at different temperatures as an index based on the respective new state (DIN EN 29073-03).

- FIG. 5 is an electron micrograph of a membrane support nonwoven fabric, which according to the invention consists of 100% low-shrink PET / PBT bicomponent fiber (nonwoven fabric F);
- FIG. 6 shows a DSC curve of a bicomponent fiber A with a crystalline sheath polymer (here PET / PBT, according to the invention).
- Fig. 7 DSC curve of a bicomponent fiber B with amorphous sheath polymer (here PET / CoPET, prior art).
- the bending stiffness is determined according to ISO 2493 in Nmm. Thermal dimensional change (shrinkage)
- the sample (DIN A4-sized pattern) is provided with markings in the longitudinal and transverse direction, which have a distance of 200 mm. After storing the sample for 1 hour at 150 0 C in a convection oven and then cooling for 20 minutes at room temperature, the dimensional change is determined. This is given, in each case for the longitudinal and transverse directions in percent relative to the initial value. The signs before the percent value indicate whether the dimensional changes are positive (+) or negative (-). The mean value is formed from at least six individual values (measurements).
- the sample (DIN A4-sized sample) is provided with markings on which the thickness is determined in accordance with ISO 9073/2. After storage of the sample for 1 hour at 150 0 C in a convection oven and then cooled for 20 minutes at room temperature, the thickness (ISO 9073/2) is determined again at the markers.
- the pad (B) is given as a percentage and calculated as follows:
- the mean value is formed from at least six individual values (measurements).
- the fiber is provided with a biasing weight as described below.
- the free fiber end is in one Clamped clamp of a terminal plate.
- the length of the clamped fiber is determined (Lt).
- the fiber is suspended without weight hanging freely 10 minutes at 170 0 C in a convection oven.
- the same weight piece from the determination of Li is again attached to the fiber and the new length determined after the shrinking process (L 2 ).
- the percentage hot air shrinkage is calculated from:
- the fiber should appear entreplexed. If the crimping is too strong, the next higher weight should be selected.
- Nonwoven A represents a drained, carded and thermally bonded nonwoven having a basis weight of 190g / m 2.
- This nonwoven fabric consists of 75% of a low shrink PET / PBT bicomponent fiber having a sheath melt point of 225 ° C and a core to sheath ratio of 50: 50 and 25% of conventional PET fibers. The thickness is 0.9 mm and the air permeability 850 l / m 2 s at 200 Pa. 14OgZm 2 of the fibers are carded over carding with transverse stretcher, the remaining 50g / m 2 are carded longitudinally.
- the nonwoven fabric is bonded in a thermal fusion furnace at about 240 0 C and calibrated with an initial press unit to the target thickness.
- Nonwoven fabric B was produced analogously to nonwoven fabric A. The difference is the use of conventional PET / Co-PET bicomponent fibers with a jacket melt point of about 200 ° C. and the reduction of the furnace temperature to 230 ° C. The resulting basis weight, thickness and air permeability are comparable.
- the nonwoven fabrics C and D represent wet laid, dried and thermally bonded nonwovens having a basis weight of 198 g / m 2 and 182 g / m 2.
- These nonwoven fabrics consist of 72% of a low-shrinkage PET / PBT bicomponent fiber with a sheath melt point of 225 ° C and a core-shell ratio of 50:50 and 28% of conventional PET fibers.
- the fibers are present as dispersible short cut fibers.
- the fibers are laid down on a wire belt in the paper-laying process, dried and thermally bonded in a second dryer.
- the outstanding properties of these nonwovens lie in the very good mechanical test values, as well as their excellent shrinkage behavior (Table 2).
- the low-shrinkage bicomponent fibers according to the invention offer advantages, since these fibers are multiply activatable in comparison to / around extended binder fibers or in the first
- the nonwovens A.C.D according to the invention are particularly suitable for use as motor oil filter medium in motor vehicles.
- calendered PET nonwoven fabrics are made of a mixture of stretched and unstretched monofilament PET fibers prior art. Due to the calendering process, there is a risk of surface sealing, especially for heavy nonwovens with basis weights> 150 g / m 2 , since high roll temperatures or slow production speeds are necessary for good penetration of the nonwoven fabric in order to bring the necessary heat into the interior of the nonwoven fabric. Sealed surfaces harbor the risk of film formation, which in turn leads to poor membrane adhesion and lower flow rates (comparative nonwoven fabric E).
- Figures 4 and 5 demonstrate the different surfaces of a conventional nonwoven fabric (comparative example, nonwoven fabric E, Figure 4) and the surface of a nonwoven fabric according to the invention (nonwoven fabric F, Figure 5).
- FIGS. 6 and 7 show DSC (differential scanning calorimetry) curves of crystalline clad polymer fibers (fiber A, here PBT) with DSC curves of conventional bicomponent fibers (fiber B, here CoPET).
- fiber A crystalline clad polymer fibers
- fiber B conventional bicomponent fibers
- the enthalpy of fusion is a direct measure of the crystalline content in the polymer.
- the core-sheath ratios of the two fibers are 1: 1, which results in the following enthalpies of fusion of the fiber sheaths:
- the core of both fibers can serve here, which consists of PET in both.
- the melting enthalpy values obtained are comparable (59 J / g vs. 54 J / g).
- the low peak height and the broader peak base are characteristic of fiber cladding based on copolymers (here CoPET).
- comonomers such as e.g. Isophthalic acid in polyethylene terephthalate, both the melting point and the crystallinity or willingness to crystallize the polymer is reduced.
- the nonwoven fabrics according to the invention are thus based on fibers of the fiber A type.
