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.

The present invention relates to a non-woven fabric with improved mechanical strength, and more particularly, to a non-woven fabric exhibiting excellent spinnability, excellent softness, and excellent tensile strength while enabling a weight reduction.

The present invention is directed to eyectrochromic, supercapacitor yarns and the related fabrics. An electrochromic yarn formed by two interwind threads has been invented. The yarn is electrically isolated by a transparent, uncolored polymer. Each thread is the superposition of three concentric layers. The most internal one, the core, has the function of support and/or conductive layer, the second one is the eiectrochromic layer containing conductive nanoparticies, the third layer is a polymer dielectric blend. The yarns described above allows to generate electrochromic fabrics in which the colour can be varied by the application of small electric voltages fed by a battery with variable power supply controlled by a microprocessor connected to a smartphone via Bluetooth technology. A specific application on the smartphone allows to change the voltage supply to the fabrics, in order to get the desired chromatic change.

The present disclosure provides a polyamide 5X staple fiber, a preparation method and use thereof. The polyamide 5X staple fiber has a denier of 8.0-30.0D, a breaking strength of 2.0-6.0 cN/dtex, and an elongation at break of 30-100%. The polyamide 5X staple fiber has good mechanical properties and softness, and a blended wool yarn for manufacturing carpets with good mechanical properties, dyeability, and wear resistance can be obtained by using the polyamide 5X staple fiber.

For providing a fabric that has a low frictional property and can exhibit long-term tribological properties even when the fabric is subjected to a high-speed frictional force under a high load, there is provided a fabric according to the present invention is a fabric in which a composite yarn of fluororesin fibers A and fibers B other than fluororesin fibers is used for at least one of a warp yarn and a weft yarn, and the fabric is characterized in that a mass ratio α of the fluororesin fibers A in the composite yarn is 5 to 70%, and a ratio of the area ratio X of the fluororesin fibers in a fabric surface to a mass ratio Y of the fluororesin fibers in the fabric is 1 or more and 5 or less. This fabric can be usefully used for a cable cover for a robot arm.

A process for foam forming webs is disclosed. The foam formed webs can be used as wiping products, such as industrial wipers, food service wipers, and the like. The web contains a mixture of cellulosic fibers and longer, strength building fibers. The web is foam formed and then subjected to one or more hydroentangling steps. After hydroentangling, the web is dried in a non-compressive manner.

Yarns including an elastomeric filament and fabrics including elastomeric filaments are described herein. A yarn may comprise an elastomeric filament and a blend of fibers, the blend of fibers comprising modacrylic fibers, meta-aramid fibers, anti-static fibers, and/or para-aramid fibers.

The present disclosure provides an airbag patch cloth that has superior packability and cutting resistance upon deployment of the airbag, and which is particularly suitable for a curtain airbag. The airbag patch cloth is a woven fabric which satisfies the following equations: P.sub.x=E/(T.sub.x×F.sub.x)×1000, P.sub.y=E/(T.sub.y×F.sub.y)×1000, wherein E indicates the kinetic energy (J) of a block and a blade. In the equations, T.sub.x indicates the average value (mm) of a torn length in the warp direction, F.sub.x indicates the linear density (dtex) of the warp constituting the fabric, T.sub.y indicates the average value (mm) of a torn length in the weft direction, and F.sub.y indicates the linear density (dtex) of the weft constituting the fabric. At least one of dynamic tear characteristics P.sub.x and P.sub.y is greater than or equal to 0.8.
