A bulky sheet (10) has a first side (11), a second side (12) opposite to the first side (11), a plurality of macroscopic first recessed ridges (21) and a projection (30) on at least the first side (11). The first recessed ridges (21) extend straight in a first direction at a predetermined interval. The projection (30) is located between the first recessed ridges (21) adjacent to each other. The projection (30) projects from the second side (12) toward the first side (11) of the bulky sheet (10).

A waved meltblown fiber web of the present invention relates to a fiber web prepared by a meltblown method and is characterized by a preparation method in which a meltblown microfiber comes in contact with collection portions having different surface velocities so as to be collected. The waved meltblown fiber web of the present invention is characterized in that: a part of meltblown microfibers reaches a low velocity collection portion so as to be horizontally layered, thereby forming a horizontal fiber layer (10); another part of the meltblown microfibers reaches a high velocity collection portion of which the surface velocity is greater that of the low velocity collection portion so as to form a serpentine vertical fiber layer (20); and the upper end of the vertical fiber layer (20) becomes entangled so as to form a wave shaped wave layer (30) forming the uppermost portion of the fiber web.
摘要:
A process of forming a non-woven web including spinning a plurality of continuous polymeric filaments from a polymeric component including a polycarbonate homopolymer component, a polycarbonate copolymer component, and combinations thereof; a polyetherimide component selected from polyetherimide homopolymers, polyetherimide copolymers, aromatic polyester homopolymers, aromatic polyester copolymers, and combinations; a polyetherimide component selected from polyetherimide homopolymers, polyetherimide copolymers, aromatic polyester homopolymers, aromatic polyester copolymers, and combinations thereof. The non-woven can be formed from continuous filaments or the filament can be chopped before forming the non-woven. Preferably, the spinning is conducted at a high rate of at least 300 grams/hour/spinneret. The continuous filaments have a diameter from 50 nanometers to 5 micrometers, preferably 50 nanometers to 2 micrometers, and a length to diameter ratio that is more than 1,000,000.

The purpose of the present invention is to provide a nonwoven fabric for use in the top sheet of an absorbent article that is unlikely to become sticky after absorbing menstrual blood, that has a silky feel, and that makes it difficult for absorbed menstrual blood to spread on the nonwoven fabric. The nonwoven fabric of the present invention has the configuration indicated below. The nonwoven fabric (5) is for use in the top sheet of an absorbent article, has a lengthwise direction (L) and a width direction (C), and is characterized in that: the non-woven fabric (5) has a plurality of units (6) in the width direction (C) that comprise four areas, namely a first area (1), a second area (2), a third area (3), and a fourth area (4) that extend in the lengthwise direction (L); the second area (2) and the fourth area (4) have a higher content by percentage of fibers that are oriented in the lengthwise direction (L) than the third area (3); the first area (1) has a higher content by percentage of fibers that are oriented in the width direction (C) than the third area (3); the second area (2), the third area (3), and the fourth area (4) respectively comprise a second area (12) containing a predetermined blood lubricity-imparting agent, a third area (13) containing the blood lubricity-imparting agent, and a fourth area (14) containing the blood lubricity-imparting agent; and in that the basis weights of the blood-lubricity imparting agent in the second area (12) containing the blood lubricity-imparting and in the fourth area (14) containing the blood lubricity-imparting agent are higher than the basis weight of the blood lubricity-imparting agent in the third area (13) containing the blood-lubricity imparting agent.
摘要:
A method of manufacturing a textured element may include (a) collecting a plurality of filaments upon a textured surface to form a non-woven textile and (b) separating the non-woven textile from the textured surface. Another method of manufacturing a textured element may include depositing a plurality of thermoplastic polymer filaments upon a first surface of a polymer layer to (a) form a non-woven textile and (b) bond the filaments to the polymer layer. A textured surface may then be separated from a second surface of the polymer layer, the second surface being opposite the first surface, and the second surface having a texture from the textured surface.

An apparatus for fabricating three-dimensional nonwoven fabric structure is disclosed, which includes an adjustable frame, a three-dimensional mold, a rotary shaft connecting the three-dimensional mold and the adjustable frame, and a meltblown device. The three-dimensional mold is rotated relative to the adjustable frame. The meltblown device has plural nozzles for spinning a plurality of fibers, wherein the three-dimensional mold is rotated in front of the nozzles to select the fibers, and a three-dimensional nonwoven fabric structure is formed on the three-dimensional mold.
