    摘要： The subject matter disclosed herein relates generally to the production of a predetermined ratio of multicomponent fibers in combination with mono component fibers or other multicomponent fibers, preferably through a spun bonding process. After extrusion, these fibers can produce a fiber network that is subsequently bonded to produce a nonwoven fabric comprising multiple types of fibers. The multicomponent fibers within the network may be processed to remove one component by dissolution or to split the individual components into separate fibers. As a result, the fabric will be comprised of fibers with a range of diameters (micro- or nano-denier fibers as well as higher denier fibers) such that the fibers will not pack as tightly as in a homogeneous nonwoven fabric produced from one type of mono component or multicomponent fiber. The present invention additionally relates to methods for producing nonwoven fabrics with increased loft, breathability, strength, compressive properties, and filtration efficiency.

    摘要： A gradient material comprising at least two types of nanofibers distributed non-uniformly throughout the material to form one or more gradients is provided. In one embodiment, the at least two types of nanofibers intertwine to form a single layer of material, i.e., are at least partially physically intertwined, i.e., entangled with one another in a multi-component material. Such intertwining can occur when both types of nanofibers are deposited substantially simultaneously in an overlapping region. In another embodiment, the at least two types of nanofibers combine to form a plurality of layers. The nanofibers can be electrospun fibers. The material can have a gradient in the planar and/or thickness directions. Embodiments of the invention also provide processes for producing the gradient nanofiber material. The materials are useful for any type of disposable garment, wipe, hospital garment, face mask, sterile wrap, air filter, water filter and so forth. Materials described herein can provide strong and varying surface effects, such as wicking. In one embodiment, hydrophobic fibers have a sufficiently small diameter to create a lotus effect.

    摘要： The present invention relates to an absorbent personal care and/or cleansing product for cosmetic and/or dermatological applications comprising at least one non-woven absorbent sheet comprising 10 to 100 wt. % lyocell fibers and 0 to 90 wt. % of at least one other natural, man-made natural and/or synthetic fiber, wherein the lyocell fiber has a fiber titer in the range from 0.5 to 3.5 dtex, wherein the absorbent sheet has a basis weight in the range from 20 to 500 g/m 2 , and a tensile strength in the range from 5 to 1000 N/5cm in machine direction and in cross direction. Further, the present invention relates to the use of said absorbent product as puffs, pads, wipes, tissues, towels, toweletts, sponges, brushes, cotton balls, gloves, mitts, cotton tip swabs or as a part thereof in cosmetic and/or dermatological applications, in particular as a basis onto which a cosmetic composition and/or dermatological cleansing and/or skin care composition, in particular in the form of a lotion, is being placed and/or into which said composition is being impregnated.
