A flat flexible hose for transporting a fluid, for example water, is adapted to move between an inoperative position having a flattened configuration and an operative position, in which the hose expands radially under pressure from the fluid. The hose has a first inner layer defining an axis, a second covering layer, and a reinforcement textile layer therebetween. The first and second layers are made of a first and respectively a second thermoplastic elastomeric material adapted to adhere to each other. The reinforcement textile layer is made of rigid textile yarns which at least partially have a respective first and second predetermined inclination opposite to each other so that the length of the hose remains unchanged both in the inoperative and the operative positions. The reinforcement textile layer is a knitted layer with tricot chain stitches with rows of stitches and courses of stitches made of chain stitches.

In one aspect, a multilayer film comprises a first skin layer having an overall density of less than or equal to 0.912 g/cm.sup.3; a second skin layer having an overall density of less than or equal to 0.912 g/cm.sup.3; and a core positioned between the skin layers, wherein the core has an overall density that is at least 0.01 g/cm.sup.3 greater than then overall density of the first skin layer, wherein the overall density of the multilayer film is from 0.905 to 0.930 g/cm.sup.3, wherein the film has a bending stiffness of 1.35 mN.Math.mm or less when the film has a thickness of 2 mils (50.8 microns), wherein the film exhibits a Gelbo flex crack performance of 2 pinholes or less in 20,000 cycles, and wherein the film comprises at least 95% by weight polyethylene based on the total weight of the film.

The invention discloses a container for the packaging of compositions comprising water water-in-oil (W/O) emulsions and/or oil-in-water (O/W) emulsions, which container comprises a tube-formed body made from a paperboard comprising a fiber based substrate comprising a first ply forming a back ply, a second ply forming a top ply and a third ply forming at least one middle ply, wherein the fiber based substrate comprises CTMP. The compositions comprising W/O or O/W emulsions may be semi-solid compositions. The invention solves the problem of delamination of the multi-ply board connected to prior art solutions. In addition, the container provides the specific barriers needed to pack compositions comprising W/O- or O/W-emulsions. It further provides the required flexibility yet rigidity to be used in such tube-formed containers.

A system that receives nanomaterials, forms nanofibrous materials therefrom, and collects these nanofibrous materials for subsequent applications. The system is coupled to a chamber that generates nanomaterials, typically carbon nanotubes produced from chemical vapor deposition, and includes a mechanism for spinning the nanotubes into yarns or tows. Alternatively, the system includes a mechanism for forming non-woven sheets from the nanotubes. The system also includes components for collecting the formed nanofibrous materials. Methods for forming and collecting the nanofibrous materials are also provided.
