The invention further relates to the use of the polymer blend composition, which has improved binding properties in a variety of end applications, particularly fibers, non-woven fabrics, and other articles made from fibers (e.g., disposable incontinence) With clothing and diapers). These fibers have good spinnability and provide fabrics with good bonding strength and good extensibility. Fibers are typically classified by diameter. Monofilament fibers are generally defined as having a fiber diameter greater than 15 denier (generally each filament is greater than% denier). Fine denier fibers generally refer to fibers having less than 15 denier per filament. Micro-denier fibers are generally defined as fibers having a diameter of less than 100 microns. Fibers can also be classified according to their preparation methods, such as monofilaments, continuously wound filaments, staple fibers or chopped fibers, spunbond and meltblown fibers. Various fibers and fabrics are made from known thermoplastic materials, such as polypropylene, high branched low density polyethylene (LDPE) typically produced in a high pressure polymerization process, linear heterogeneous branched polyethylene (for example, using Ziegler catalyst for linear low-density polyethylene), blends of polypropylene and linear heterogeneous branched polyethylene, linear heterogeneous branched polyethylene seed copolymers, and ethylene / vinyl alcohol copolymers . Among the various polymers that can be extruded into fibers, the high branched dagger 01 ^ has not been successfully melt-spun into fine denier fibers.

The disclosed composition preferably comprises a homogeneous linear polymer having a bifurcation of at least 0 89 g / cm3. However, Lai et al. Revealed that the preparation temperature was only above 165 ° C. In contrast, to maintain the integrity of the fibers, fabrics are generally bonded at a temperature of less than 165 C, so that all crystalline materials are not melted before or during the fiber bonding step. Although various olefin polymer compositions have been found to be successful in several types of fibers and fabric applications, fibers made from these compositions can benefit from improved bond strength, which can result in stronger fabrics, and therefore increase non-compliance. Weaving and part preparation and end consumer value. But any benefit of bond strength should not be detrimental to the unfavorable reduction in spinnability and fiber elongation, and to unfavorably increase the adhesion of the fiber or fabric to the device during processing. We have found that the inclusion of high molecular weight ethylene polymers in polypropylene polymers with face visbreaking, coupling, branching, or stable melt flow generally provides an array of fibers and calendered fabrics with improved bonding properties while maintaining Excellent fiber spinnability and elongation.

In general, the excellent polymer spinnability can be achieved even if the ethylene polymer itself cannot be spun into fine denier fibers when used (that is, the gan # is less than about 50 denier). It is also unexpected that the improved bonding strength can be obtained without reducing the fiber elongation by the same amount. Surprising improvements have been obtained at relatively low polymer densities and crystallinity relative to known pp / HDPE blends. Another surprise is that the blends based on the high molecular weight ethylene / aromatic vinyl heteropolymers of the present invention can provide dramatic improved bond strength, while the blends based on ethylene olefin heteropolymers The compounds do not provide significant improvements when compared to the similar crystallinity and 12 melt index.

The preferred range is greater than 155,500, the more preferred range is greater than 150,000, and the most preferred range is greater than 250,000 to obtain the desired high mechanical strength in the final product. For fiber preparation, especially fiber spinning, the melt flow rate of polypropylene polymers (coupling, branching, visbreaking, or stabilization) is measured at 230 and 2.16 kg weight (ASTM D_1238). It is preferably greater than or equal to 20 g / 10 minutes, more preferably greater than or equal to 25 g / 10 minutes, and especially in the range of 25 to 50 g / 10 minutes, and most preferably 30 to 40 g / 10 minutes. minute. The polypropylene polymers used in the present invention can be branched or coupled to provide increased nucleation and crystallization rates. The term, coupling, is used herein to refer to a rheologically modified polypropylene polymer, as such, it is exhibited during fiber preparation operations (for example, in an extruder in front of a godet in a fiber spinning operation) Resistance of molten polymers to fluidity. However, visbreaking is related to the direction of bond cracking, and coupling is related to the direction of the parent network.

Description of the Invention (34) It is not intended to limit the scope of the present invention in any way. One way to accomplish this polymerization reaction method is as follows. In the stirred tank reactor, the olefin is continuously introduced through the monomer together with the solvent and the polyene. The reactor contains a liquid phase consisting essentially of the monomer together with any solvent or additional diluent. The catalyst and co-catalyst are continuously introduced into the reactor liquid phase. The temperature and pressure of the reactor are controlled by adjusting the solvent / monomer ratio, the catalyst addition rate, and by both the cold section or the heating coil and the jacket. The polymerization rate is controlled by the catalyst addition rate. The molecular weight of the polymer product is selectively controlled by controlling other polymerization variables, such as temperature, monomer concentration, or fluid or hydrogen introduced to the reactor, and is known in the industry. The reactor effluent is in contact with a catalyst inhibitor such as water or alcohol. The polymer solution is selectively heated, and the polymer product is flashed off by gaseous monomers and residual solvents or diluents under reduced pressure and, if necessary, further discharged in a device such as an exhaust extruder Recycling. In a continuous process, the average residence time of the catalyst and polymer in the reactor is generally 5 minutes to 8 hours' and preferably 10 minutes to 6 hours. Preferably, the polymerization reaction is carried out in a continuous solution polymerization reaction system, optionally comprising more than one series or parallel connected reactors.

However, it is preferably a homogeneously branched ethylene polymer and an ethylene vinyl or vinylidene aromatic monomer heteropolymer, and the best is a homogeneously branched substantially linear ethylene polymer and a substantially random ethylene / vinyl Aromatic heteropolymer. The substantially homogeneous branched substantially linear ethylene polymer used in the polymer blend composition disclosed herein is a heteropolymer of ethylene and at least one C3-C2ka thin smoke. As used herein, heteropolymers, and "ethylene polymers," refer to polymers that can be copolymers or terpolymers. They are generally copolymerized with ethylene to produce homogeneous branched linear or substantially linear ethylene polymers. The monomers include ere.

After the first carding, the fibers were removed, re-supplied to the SpinLab Rotor Ring 580 unit, and another 45 seconds were recorded.

An optical micrograph of the cross-section of the carded cut fibers of Example 1 of the present invention was obtained (Figure 1). The cut fibers that had been carded before taking optical micrographs were colored with R11CI3 / oxygenate and mounted with ΕρΟχχΜ. The optical micrograph itself shows that before the thermal bonding, the cross-sectional structure of the polypropylene polymer (continuous polymer phase) and the ethylene polymer (discontinuous phase) is of the sea-island type, and the polypropylene polymer constitutes a carded section The surface of the fiber is more than 50%. That is, before thermal bonding, the discontinuous phase does not occupy a large portion of the fiber surface. For Examples 3 and 9, the same results and characteristics are shown in Figures 2 and 3. Distinct from the discontinuous phase, it is non-highly dispersed (relatively larger particles) and occupies a fibrous surface that is about as much as the weight percentage contained in it (ie, there is no better migration on the surface or substantially High concentration), Figure 3 also shows that the discontinuous substantially random ESI phase has at least two components.
