A non-woven textile may be formed from a plurality of thermoplastic polymer filaments. The non-woven textile may have a first region and a second region, with the filaments of the first region being fused to a greater degree than the filaments of the second region. A variety of products, including apparel (e.g., shirts, pants, footwear), may incorporate the non-woven textile. In some of these products, the non-woven textile may be joined with another textile element to form a seam. More particularly, an edge area of the non-woven textile may be heatbonded with an edge area of the other textile element at the seam. In other products, the non-woven textile may be joined with another component, whether a textile or a non-textile.

A heat resistant fiber assembly contains heat resistant fibers having a glass transition temperature of 100 C. or more, the heat resistant fibers being bonded together.

The disclosure relates to the technical field of nonwoven fabric manufacturing, in particular to a novel antibacterial breathable fabric and a preparation method thereof. The preparation method includes following steps: S1, surface hot rolling treatment: performing the surface hot rolling treatment on a fiber mesh layer, where a lower surface of the fiber mesh layer is supported by a flexible belt, and a hot rolling member contacts and hot rolls an upper surface of the fiber mesh layer, so as to prepare the fiber mesh layer with fibers on the upper surface thermally bonded and fibers on the lower surface fluffy; and S2, spunlace processing treatment: performing the spunlace processing treatment on the lower surface of the fiber mesh layer prepared in the S1; and the flexible belt is made of a high-temperature resistant flexible material.

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.

A molded and shaped acoustical insulating vehicle panel having a dry-laid needled fibrous composite composed of a first portion of about 50 to 80 percent meltable binder fibers and about 20 to 50 percent stable fibers and having a second portion of about 20 to 50 percent meltable binder fibers and 50 to 80 percent of staple fibers. The meltable binder fibers are in a molded and resolidified state such that the resolidified binder fibers of the first portion form a substantially continuous, semi-impervious, densified skin integrally associated with and bonded to a surface of the first portion. The molded composite is in such a heat and pressure molded state that the composite has over a predominance of its area a density of from about 12 to 22 lbs./cubic foot (192 to 352 kg/cubic meter) and the panel is sufficiently rigid as to be self-supporting.
