A tubular braid, a hollow fiber membrane using the same, and a manufacturing method thereof. A hollow fiber membrane can maximize or increase adhesion between a polymer coating film and a tubular braid; significantly reduce degradation of film properties caused by non-uniform coating, that is, reduce leakage; obtain a higher percent rejection; and achieve high water permeability since the hollow fiber membrane has a larger inner diameter.

A braid separation apparatus for separating rope strands of a braided rope, thereby allowing reuse of the separated rope strands, is provided and may include an input assembly configured to move a braided rope made of at least three rope strands, into the apparatus. Further, the apparatus may comprise three or more winding carriers, each being coupled to one of the rope strands. The winding carriers configured to move about each other in serpentine path such that rope strands of the braided rope are separated. Each winding carrier may comprise a spool which is connected to the rope strand coupled to the winding carrier. Each winding carrier may further comprise a torque creating unit configured to provide a torque on the spool and to cause the spool to rotate such that the rope strand is wound around the spool.

Interlacing equipment may be used to form fabric. A component detector may be used to feed strands such as a conductive strand to the interlacing equipment. One or more electrical components may be mounted to the conductive strand. The component detector may have a sensor configured to detect the presence of the electrical component as the conductive strand is fed to the interlacing equipment through the component detector. In response to detecting the component with the sensor, the interlacing equipment may automatically adjust interlacing operations in preparation for receiving the electrical component. For example, needles may be lowered in a knitting system, select warp strands may be raised and lowered in a weaving system, or a carrier may follow a modified path in a braiding system in response to detecting the electrical component. The fabric may have a different construction in regions where the electrical component is received.

In some aspects, a device comprises a plurality of walls defining one or more channels; wherein the one or more channels have a cross-section in a plane perpendicular to a vertical axis of the device that changes along the vertical axis; and one or more floats sized to allow movement of the one or more floats within said one or more channels, wherein the one or more floats have a surface characteristic that is different from the surface characteristic of the walls such that, upon contact with a fluid, said walls and said floats form different contact angles and induce a repulsive capillary force between the walls and the one or more floats at a surface of the fluid.
