摘要： Provided is a conjugate fiber for air-laid nonwoven fabric manufacture having a planar zig-zag crimp shape before a thermal treatment, such that a uniform web is obtained by air laying with high processability and productivity, and the conjugate fiber develops a spiral crimp when the web is subjected to a thermal treatment to thereby enable the web to shrink significantly, as a result of which a nonwoven fabric can be obtained in which fibers are amassed to a high density.The conjugate fiber for air-laid nonwoven fabric manufacture is a heat-fusible conjugate fiber in which a first component comprising an olefinic thermoplastic resin is conjugated with a second component comprising an olefinic thermoplastic resin having a melting point higher than that of the first component. The conjugate form is such that the centers of gravity of the conjugate components are mutually different in the fiber cross section, the fiber has a single-yarn fineness of 1 to 10 dtex, a fiber length of 3 to 20 mm, and a planar zig-zag crimp whose crimp shape index (actual length of short fiber/distance between both ends of short fiber) ranges from 1.05 to 1.60, and the web shrinkage upon thermal treatment at 145° C. of a web obtained by an air-laid method is not lower than 40%.

摘要： High loft, low density nonwoven webs are produced by forming substantially continuous, spunbond, crimped, bicomponent fibers of A/B bilateral morphology in an unheated fiber draw unit. The fibers are then heated and cooled in the absence of impeding forces to achieve maximum crimp in the z-direction and produce a web of lofted material. The resultant material is particularly suitable for use as an insulator. Particulates may be added to the webs if desired.

摘要： A method of producing self-texturing filaments that exhibit a desirable tendency to coil rather than to bend sharply or zig zag. The method includes directing a quenching fluid at extruded hollow filaments of a liquid polymer predominantly from one side of the hollow filaments to thereby produce hollow filaments with different orientations on each side. Thereafter the temperature of the hollow filaments is raised to a temperature sufficient for the filaments to relax, but less than the temperature at which the filaments would shrink. When the relaxed filaments are cut into staple lengths, they tend to assume a form that provides a favorable degree of mechanical entanglement that is useful in forming resilient solid structures.
摘要翻译：一种产生自织物长丝的方法，其显示出期望的线圈倾向而不是急剧弯曲或锯齿形。该方法包括将主要来自中空丝的一侧的液体聚合物的挤出中空丝引导到淬火流体，从而在每一侧上产生具有不同取向的中空丝。此后，将中空丝的温度升高到足以使细丝松弛的温度，但是小于长丝收缩的温度。当松弛的长丝被切割成短纤维长度时，它们倾向于呈现出有助于形成弹性固体结构的有利程度的机械缠结的形式。

摘要： A thermobondable bicomponent synthetic fiber (8,14) with a length of at least about 3 mm, adapted to use in the blending of fluff pulp for the production of hygiene absorbent products, the fiber comprising an inner core component comprises a polyolefin or a polyester, the sheath component comprises a polyolefin, and the core component has a higher melting point than the sheath component, and a process for producing said fiber. The sheath-and-core type fiber is preferably made permanently substantially hydrophilic by incorporating s surface active agent into the sheath component. The long bicomponent fibers (20) form a strong supporting three-dimensional matrix structure (20,24) in the absorbent product upon thermobonding.

摘要： A fiber entanglement is provided which is characterized in that it is a three-dimensional entanglement comprising elastic fibers (A) each being a fine-denier fiber bundle or exhibiting porous fiber structure as seen on a fiber cross section with a number of irregularly-shaped pores extending in the fiber axis direction; nonshrinkable, nonelastic fibers (B); and shrinkable, nonelastic fibers (C); said fibers (A) are at least partially bonded or fused together at various points of contact with one another and, thereby, produce a taut condition; said nonshrinkable, nonelastic fibers (B) are folded several times over by means of the elastic fibers (A) and the shrinkable, nonelastic fibers (C). This fiber entanglement is useful as a base material for leather-like sheet materials.
