A method of healing an external wound involves applying an external wound-healing agent to an external wound, or bringing the external wound-healing agent applied to a substrate into contact with an external wound, wherein the external wound-healing agent includes, as an active ingredient, at least one compound of a glycerol alkyl ester represented by defined Formula (I) or a diglycerol alkyl ester represented by defined Formula (II). In a further embodiment, the method involves bringing a fiber aggregate or a film into contact with an external wound, wherein the fiber aggregate or the film each includes a thermoplastic resin and at least one compound of the glycerol alkyl ester or the diglycerol alkyl ester.

External wound-healing agent, and external wound-healing material

Apparatus for manufacturing a non-woven fabric includes a diffusing shaft, which includes a first shaft portion in a defined location and provided with a slit-shaped air guide, wherein filaments are supplied together with air from an inlet side of the air guide to an outlet side of the air guide; a second shaft portion in a defined location, having an inlet side that is communicated with an outlet side of the first shaft portion and an outlet side that is disposed to face a filament collecting unit, wherein an opening width along a machine direction of the inlet side of the second shaft portion is larger than an opening width along a machine direction of the first shaft portion; and a stepped portion provided at a connecting portion between the outlet side of the first shaft portion and the inlet side of the second shaft portion and connecting the same.

Apparatus for manufacturing non-woven fabric and method of manufacturing non-woven fabric

A mixed fiber spunbonded nonwoven fabric which comprises 90 to 10% by weight of a long fiber of thermoplastic resin (A) that has been hydrophilization-treated and 10 to 90% by weight of a long fiber of thermoplastic elastomer (B) and which has a strength ratio [the ratio of a strength at 20% of an elongation at a maximum strength (elongation at a maximum point) to the maximum strength] in at least one direction of not more than 40% and a bulk density of 0.10 to 0.40 g/cm. The fabric can exhibit excellent initial hydrophilicity, long-lasting hydrophilicity, liquid dispersibility, liquid transpiration property, moisture permeability, breathability, softness, resistance to fluff, stretchability and touch, and low stickiness, and is suitable for sheets constituting absorbent articles such as sanitary napkins, panty liners, incontinence pads, and disposable diapers. A production method is also provided.

Method for producing a mixed fiber spunbonded nonwoven web

A non-woven fabric laminate that is excellent in strechability, flexibility, and bulkiness, and that is less sticky and is suitable for a mechanical fastening female material. The non-woven fabric laminate includes a mixed fiber spunbonded non-woven fabric and a non-woven fabric comprising a crimped fiber that is laminated on at least one face of the mixed fiber spunbonded non-woven fabric, which includes a continuous fiber of a thermoplastic elastomer (A) in the range of 10 to 90% by weight and a continuous fiber of a thermoplastic resin (B) in the range of 90 to 10% by weight (where (A)+(B)=100% by weight). The non-woven fabric laminate can be suitably used for a sanitary material and other materials. More specifically, there can be mentioned for instance an absorbent article such as a disposable diaper and a menstrual sanitary product as a sanitary material.

Non-woven fabric laminate

A nonwoven fabric laminate possesses excellent elasticity, softness, water resistance, fuzz resistance and curl resistance, and has less stickiness. The nonwoven fabric laminate includes at least one meltblown nonwoven fabric layer and mixed-fiber spunbonded nonwoven fabric layers on both surfaces of the at least one meltblown nonwoven fabric layer, the mixed-fiber spunbonded nonwoven fabric layers each comprising mixed fibers including 10 to 90 wt % of continuous fibers of a thermoplastic elastomer (A) and 90 to 10 wt % of continuous fibers of a thermoplastic resin (B) other than the thermoplastic elastomer (A) ((A)+(B)=100 wt %).
