When used as a surface material of hygiene products such as diapers, sanitary napkins, or wet wipes, it is possible to provide consumers with high quality hygiene products. In addition, since calcium carbonate replaces a certain amount of polyolefin-based resin, especially polypropylene, which is a raw material for manufacturing short fibers or nonwovens, the production cost can be reduced by about 4 to 7% compared to using polypropylene only when producing 1 kg of nonwoven fabrics. Can be.

One aspect of the present invention relates to a polyolefin-based short fibers for hygiene products and a method for producing the same.

The polyolefin short fibers for sanitary ware according to the present invention are formed by spinning a composite melt composed of 70 to 97% by weight of polyolefin resin and 3 to 30% by weight of calcium carbonate and stretching the spun undrawn yarn.

The polyolefin resin used to prepare the polyolefin short fibers for hygiene products according to the present invention may be composed of one or more resins selected from the group consisting of polyethylene, polybutylene, and polypropylene, and specifically, polypropylene ( PP), polyethylene (PE), polybutylene (PB) and the like may be homopolymers or random copolymers or block copolymers of olefins, and may be mixtures of polyolefins with other polyolefins. In addition, the polyolefin-based resin is preferably characterized by consisting only of homo polypropylene. The homopolypropylene has a Melt Flow Index (MFI) of 3 to 30 g / 10 min, measured according to ASTM D1238, and an Isotactic Index (II) of 90% or more, measured according to ISO 9113. Preferably, it is 90 to 99%, and the melting point measured by a differential scanning calorimeter (DSC) is preferably 160 to 165 ° C, but the content of the present invention is not limited only to the above range. The lower the melt flow index of the homopolypropylene can impart the rigidity, chemical resistance, and low elongation of the fiber, but the workability is worsened because the viscosity is lowered. If the melt flow index is too high, the spinning is difficult, so it is 3 to 30 g / 10 min. Having a melt flow index is most suitable for fiber spinning. In addition, the isotactic index should be 90% or more to obtain short fibers having excellent polypropylene crystallinity and rigidity, and polypropylene having more than 99% is practically difficult to commercialize.

Durability is improved.

The composite melt which is a raw material of the polyolefin short fibers for sanitary ware according to the present invention is composed of 70 to 97% by weight of polyolefin resin and 3 to 30% by weight of calcium carbonate based on the total weight of the composite melt, preferably polyolefin resin. 80 to 90% by weight and 10 to 20% by weight of calcium carbonate. When the calcium carbonate content in the composite melt is less than 3% by weight, the effect of the addition of calcium carbonate on the whiteness of the nonwoven fabric increases the visually clean feeling, the volume on the basis weight, and the durability on the increase in tensile strength. Inadequate and more than 30% calcium carbonate content is poor radioactivity of the composite melt, making it difficult to commercially produce polyolefin-based short fibers for hygiene products. In addition, when the calcium carbonate content in the composite melt is 10 to 20% by weight, the radioactivity during the polyolefin short fiber manufacturing process, the carding property and the uniformity during the nonwoven fabric manufacturing process are good, and the durability and whiteness due to the increase in tensile strength are good.
