A non-woven fabric comprising bicomponent fibers. The non-woven fabric has a core containing polylactic acid (PLA-1), coated with an envelope containing polylactic acid (PLA-2). The fibers are characterised in that PLA-1 is a copolymer of lactic acid monomers L1 and lactic acid monomers D1, and PLA-2 is a copolymer of lactic acid monomers L2 and lactic acid D2, whose D2 monomers rate is greater than the monomers rate D1 of PLA-1. The core further contains a polymeric plasticizer. The non-woven fabric may be used for making coffee filters and/or capsules via a thermoforming process for use in a percolating apparatus.

The present invention relates to meltblown non-woven fabric, multi-layered spunbonded non-woven fabric comprising same, and a method for manufacturing same, and to: meltblown non-woven fabric which uses recycled polyester flakes, thus being environmentally friendly, and is a material used in a sound absorbing material for automobiles due to the excellent rigidity, sound absorption capability and compressive modulus thereof, and thus can be used in automobile interior materials that require rigidity, sound absorption capability, and compressive modulus, such as wheel guards and trunk trims of automobiles; multi-layered spunbonded non-woven fabric comprising same; and a method for manufacturing same.

An oil absorber is disposed around a rotational driving unit of a robot and absorbs an oil component. The oil absorber includes a defibrated material obtained by defibrating fibers, and a binding material that binds the fibers together. The rotational driving unit includes a motor and a speed reducer coupled to one end portion of the motor. The oil absorber is disposed at least at one of an outer circumferential portion of the speed reducer, surroundings around the motor, and the other end portion of the motor.

Thermally stable absorbable fiber populations, i.e. fiber populations that do not undergo thermally induced crystallization, can be intermixed with thermally unstable fibers to yield a stabilizing effect without altering morphological properties of a fiber system. Via this, one may minimize thermally induced shrinkage and maintain physical properties of electrospun materials in the as-formed state.

The invention provides a discrete fiberfill cluster that is made up of a plurality of fibers that are randomly intermingled with one another. Within the plurality of fibers there are 25 to 3600 fibers having a denier of 0.2 to 12.0 and a length of 8 to 160 mm. The plurality of fibers are randomly and non-uniformly oriented with respect to one another. Within the discrete fiberfill cluster, there are: one or more relatively densely populated regions of fibers having a first degree of entanglement; and, proximate to at least one of the one or more relatively densely populated regions, one or more relatively less densely population regions of fibers having a second degree of entanglement that is less than the first degree of entanglement.
