The device is for preparing a liner to be installed in a pipe. The device has a frame, which is rotationally symmetrical in relation to its rotational axis. The frame has two ends, in the middle of both of which ends is arranged an opening. The device further has two rings in connection with the frame, which are equally large in their outer diameter. The outer diameter is larger than the outer diameter of the frame in the section between the rings.

A spray coating apparatus is provided, wherein a nozzle is arranged to traverse a fabric in one direction whilst simultaneously spraying and oscillating in another direction. The fabric is spray coated with a first pass having a spray zone having uneven distribution in the direction of oscillation, and particularly with a greater density of fluid coverage toward the centre of the spray zone than an edge. The nozzle forming a second and subsequent pass that is off-set from the first and each subsequent pass respectively. The second and each subsequent pass being arranged to overlap with a portion of the previous pass, thereby providing an improved distribution of the spray coating. Moreover, because the spray coating is incremental, the method is easily adaptable to integrate with an ink jet printing process.

Provided are an apparatus for manufacturing a textile grid with increased adhesion and a method thereof capable of integrating the textile grid with a concrete structure by increasing the adhesion of the textile grid when the concrete structure is built, repaired, or reinforced, increasing structural safety and durability of the concrete structure, increasing a working speed by coating a surface of the textile grid with an abrasive material powder that is a surface coating material in an automatic series of processes immediately after the textile grid is manufactured, and increasing coating performance by automatically inspecting and adjusting the amount of the coating material applied to the surface of the textile grid using a camera.

Fabric sheet assemblies for delivering malodor control in wash liquor during a laundering process and methods for forming such fabric sheet assemblies are provided. In one example, a fabric sheet assembly includes one or more substrate layers including a first substrate layer. The first substrate layer is configured to absorb and/or adsorb malodor compounds from the wash liquor. An odor controlling composition is carried by the one or more substrate layers and is configured to be released into the wash liquor.

An embodiment herein provides a process for dyeing of textile materials 108 with supercritical fluid. One or more dye materials 102 along with additives (if required) are mixed with at least one suitable solvent 104 to obtain one or more dye solutions 106. A textile material 108 is pre-treated with the one or more dye solutions 106 to obtain a dye coated textile material 110. The dye-coated textile material 110 is exposed to the supercritical fluid 112 in a supercritical fluid dyeing vessel at controlled pressure and temperature. The supercritical fluid 112 solubilizes and diffuses the one or more dye materials 102 inside the surface, pores and capillaries of the textile material 108. The supercritical fluid vessel is then depressurized below supercritical condition to entrap the one or more dye materials 102 in the textile material 108 to obtain a supercritical fluid dyed textile material 114.

A woven fabric that has the appearance of a neoprene fabric is obtained with a double face fabric in which the warp yarns passes at least three weft yarns on each side of the fabric.

A device for applying a foamed treating material under pressure to a traveling sheet of relatively incompressible textile yarns. A foam applicator unit has a nozzle with a foam dispensing slot facing across one side of the traveling sheet of yarns. A drive roll faces the other side of the traveling sheet of yarns in tangential alignment with the foam dispensing slot. The roll has a resiliently compressible, soft rubber outer layer, which compresses to conform with the surface of the relatively incompressible yarns and presses the traveling sheet of yarns against the applicator surfaces leading to and away from the slot to prevent escape of foam and to prevent passage of foam between yarns to maintain uniform distribution of foam applied to the traveling sheet of yarns.

Electret webs include a thermoplastic resin and a charge-enhancing additive. The charge-enhancing additive is a fused aromatic thiourea, a fused aromatic urea compound, or a combination thereof. The change-enhancing additive may also include a hindered amine light stabilizer compound. The electret webs may be a non-woven fibrous web or a film. The electret webs are suitable for use as filter media.
