Method and apparatus for producing nonwoven materials
09828708 · 2017-11-28 ·

A method of producing a needled product of a selected material or materials of a desired thickness and size. A first carded batt of a selected material or materials is moved from a feed support into a needle loom between a vertically reciprocating needle bed and a support bed located beneath and in spaced relation to the needle bed. The needle bed and/or the support bed are vertically movable to vary the spacing therebetween. The upper surface of the first carded batt is penetrated by the needles in the needle loom so that the needles do not reach an upper surface of the support bed and are able to flex laterally. The needled first batt is then lifted and moved to the feed support or a feed support for another needle loom. Thereafter, a second batt is positioned over the first batt in overlapping relation, the needle bed or support bed is moved to increase the vertical spacing therebetween to accommodate the overlapped batts, and the batts are moved through the needle loom and connected. This method may be repeated to add additional overlapped batts to produce a layered product of any suitable thickness.

NON-WOVEN FABRIC BOARD FOR EXTERIOR OF VEHICLE AND METHOD FOR MANUFACTURING SAME
20170306538 · 2017-10-26 ·

A non-woven fabric board for an exterior of a vehicle and a method for manufacturing same are provided. The non-woven fabric board includes a matrix fiber having a non-circular cross-section and an adhesive fiber having a non-circular cross-section, and the matrix fiber is included in an amount of 50 wt % or greater based on the total weight of the non-woven fiber board. Each of the matrix fiber and the adhesive fiber have a linear density of about 6 to 15 denier and a degree of non-circular shape of about 1.3 to 3.0.

The non-woven fabric board for an exterior of a vehicle has a substantially increased specific surface area by using the non-circular cross-section fibers, improved adhesion efficiency between fibers, and substantially improved mechanical properties. In addition, heat moldability thereof is improved, weight thereof is reduced, and the sound-absorbing performance thereof is substantially improved.

Method for forming a non-woven recyclable fabric

A nonwoven recyclable fabric and associated methods are provided. The fabric is formed from 100% polyester, and may also include surface coatings such as hydrophilic coatings to promote heat transfer as well moisture vapor transmission rates and/or a silicone coating to promote fabric smoothness and reduce abrasiveness of the fabric.

THREE-DIMENSIONALLY PATTERNED NON-WOVEN HAVING STRESS RECOVERY

A nonwoven web made of substantially continuous fibers and comprising a three-dimensional pattern of protruding closed shapes, wherein the nonwoven web has a compression recovery of at least 30% after being compressed at 1 psi for 24 hours.

METHOD AND DEVICE FOR PRODUCING AN ANNULAR MULTIAXIAL LAID FABRIC AND AN ANNULAR OBJECT PRODUCED THEREWITH

The invention relates to a method and a device for producing an annular multiaxial laid fabric and to an annular object produced therewith. The object of the invention is therefore to create a method and a device for forming a multiaxial laid fabric for annular structures which has no twisting or displacement of the thread layers. Furthermore, it should no longer be necessary to close a butt join or overlap separately to form a closed ring of the multiaxial laid fabric. This object is achieved in that at least a lower thread layer (2a) and an upper thread layer in the form of an endless thread array or an endless single thread, or in the form of thread-array sections or single-thread sections, are laid around the entire circumference of two mutually spaced ring elements (3) with differing thread orientations, and the first and upper thread layers (2a, 2b) are then fixed to each other at points.
