Problems solved by technology

However, in these cases, the nonwoven fabric obtained has low softness and causes strong physical irritation to the skin
On the other hand, when giving priority to the softness of suppressing irritation to the skin, the bulkiness (especially in the cushioning effect (cushioning effect)) of the obtained nonwoven fabric is greatly reduced, so it shows unsatisfactory performance. Fluid Absorption Properties

example

[0106] Hereinafter, the present invention is explained with reference to examples, but the present invention is not limited to these examples. In each example, physical evaluation was performed by the method mentioned later.

[0107] (thermoplastic resin)

[0108] The following resins were used as thermoplastic resins constituting the conjugate fibers. Resin 1: high-density polyethylene (abbreviation: PE), its density is 0.96 g / cm3, MFR (190°C, load: 21.18N) is 16 g / 10 minutes, melting point is 130°C; resin 2: Polypropylene crystal (abbreviation: PP) with an MFR (230°C, load: 21.18N) of 5 g / 10 minutes and a melting point of 162°C; Resin 3: polyethylene terephthalate (abbreviation: PET), which The intrinsic viscosity is 0.64, and the glass transition temperature is 70°C.

[0109] (How to add inorganic fine particles)

[0110] The following method was used as a method for incorporating inorganic fine particles into the composite fiber.

Abstract

The object of the present invention is to provide a heat-adhesive composite fiber, a manufacturing method thereof, and a non-woven fabric using the same. The above-mentioned heat-bonding composite fiber can maintain the stability of the crimped structure even in the state where the fiber is stretched, and can impart bulkiness and softness to the nonwoven fabric. The heat-adhesive composite fiber provided by the present invention includes a first component containing a polyester resin and a second component containing a polyolefin resin. The above-mentioned polyolefin-based resin has a melting point lower than that of the above-mentioned polyester-based resin, wherein the above-mentioned second component occupies a specific range of outer fiber circumference and has a side-by-side eccentric sheath-core structure, and the thermally bonded composite fiber has a specific elongation rate, a specific range of three-dimensionally developed curl, and a specific range of curl modulus.

Description

technical field [0001] The present invention relates to a heat-bonding composite fiber, and more particularly to a heat-bonding composite fiber whereby a nonwoven fabric or the like having excellent softness can be obtained. More specifically, the present invention relates to a heat-bonding composite fiber that can obtain, for example, a nonwoven fabric having excellent softness and being suitable for various applications, and a nonwoven fabric having excellent softness using the same. The aforementioned applications are, for example, absorbent articles for cleaning materials such as diapers, napkins and liners, medical and hygiene materials, life-related materials, general medical materials, cushion materials, filter materials, care products and pet products. Background technique [0002] Conventionally, thermal bonding composite fibers formable by thermal fusion using thermal energy such as hot air and heated rolls can easily provide nonwoven fabrics with excellent bulkine...
