This application relates to a high-strength protective cloth with moisture permeability and a manufacturing method thereof. The method includes: providing a first fiber thread and a second fiber thread; respectively forming a moisture-permeable membrane on a surface of an arrangement layer formed by the first fiber thread and a surface of an arrangement layer formed by the second fiber thread; and combining the first fiber thread and the second fiber thread in pairs by intersecting and laminating to form laminated bonding, where the first fiber thread and the second fiber thread with the moisture-permeable membrane are used as two opposite surface layers of the laminated bonding to allow the laminated bonding to form a corresponding moisture-permeable membrane layer. This application provides a high-level protective cloth with excellent moisture permeability and high-strength protective performance, and optimizes the moisture permeability of the protective cloth.

A fiber aggregation contains fiber containing a thermoplastic resin, each of the fiber being mutually joined and aligned.

Disclosed is a new multi-layer nonwoven interlining and the production process thereof. The process allows a multi-layer nonwoven interlining to be obtained simultaneously with a single process on a single production line. The process includes a fiber opening step, a fiber feeding step, a carding step, a levelling step of the additional layer by the thermal treatment, and a point bonding step of the carded web and additional layer. As a result of the process, a structure is obtained where the carded web is point-bonded onto the additional layer.

A method for the production of a continuous nonwoven fabric from fiber mixtures of carrier fibers and binding fibers, comprising the steps: a. Feeding fibers; b. Breaking up, combing and opening out the fibers; c. Mixing the fibers; d. Sucking the fibers between two opposing airpermeable conveyor belts running at identical speed, such that the air is sucked from the outside in the front section of the conveyor belts in such a way that the air flow is always sucked through the deposited nonwoven fabric by air extraction at different times and different locations across the width and parallel to the conveyor belts and the fibers are thereby positioned perpendicular to the surface of the conveyor belts; e. Thermally solidifying the nonwoven fabric created by heating with hot air or shortwave radiation and cooling. Also a nonwoven fabric production apparatus.

A method for arranging nanotube elements within nanotube fabric layers and films is disclosed. A directional force is applied over a nanotube fabric layer to render the fabric layer into an ordered network of nanotube elements. That is, a network of nanotube elements drawn together along their sidewalls and substantially oriented in a uniform direction. In some embodiments this directional force is applied by rolling a cylindrical element over the fabric layer. In other embodiments this directional force is applied by passing a rubbing material over the surface of a nanotube fabric layer. In other embodiments this directional force is applied by running a polishing material over the nanotube fabric layer for a predetermined time. Exemplary rolling, rubbing, and polishing apparatuses are also disclosed.

A fabric of nanofibers that includes an adhesive is described. The nanofibers can be twisted or both twisted and coiled prior to formation into a fabric. The adhesive can be selectively applied to or infiltrated within portions of the nanofibers comprising the nanofiber fabric. The adhesive enables connection of the nanofiber fabric to an underlying substrate, even in cases in which the underlying substrate has a three-dimensional topography, while the selective location of the adhesive on the fabric limits the contact area between the adhesive and the nanofibers of the nanofiber fabric. This limited contact area can help preserve the beneficial properties of the nanofibers (e.g., thermal conductivity, electrical conductivity, infra-red (IR) radiation transparency) that otherwise might be degraded by the presence of adhesive.
