A cloth washing device contains a washing machine and a fiber opener. The washing machine includes multiple transmission rollers arranged on water and multiple bearings fixed in the water. The fiber opener includes multiple transmission rollers arranged on the water, multiple bearings fixed in the water, and at least two mesh wheels arranged in the water. The fiber opener is mounted behind the washing machine, and a cloth is delivered between the washing machine and the fiber opener by way of the multiple transmission rollers and the multiple bearings of the washing machine and the fiber opener and the least two mesh wheels.

Processes and apparatus are disclosed which substantially eliminate the formation of oxidized indigo dye before and during dye application onto a natural fiber yarn or fabric while allowing the leuco-indigo dye molecule to diffuse fully into the natural fibers of the yarn where it can fix to the fibers prior to oxidation (i.e., exposure of the leuco-dyed yarns to oxygen). Indigo dyed textile products (e.g., dyed cotton yarns that may be twill woven to form a denim fabric) exhibit exceptionally high colorfastness as determined by the AATCC Crock Test.

Metal drum dryer, the side surface of which is constituted of U-shaped profiles (1), each having a bottom, each profile (1) is welded to the two neighbouring profiles (1) thereof and the bottom of each profile (1) is pierced with holes (4).

A dyeing machine with symmetrical double spiral fabric tanks includes a barrel body with a fabric inlet, two spiral fabric tanks arranged side by side with each other in the barrel body and installed on both sides of the fabric inlet respectively, and each spiral fabric tank having a fabric guiding tube, a spiral fabric sliding plate and a receiving tank. The two fabric guiding tubes are disposed proximate to adjacent sides and facing to the front side and arranged symmetrically with respect to the left and right sides. The two spiral fabric sliding plates are coupled to the rear end of the two fabric guiding tubes and configured to be spirally from top to bottom, so that cloths can be dipped and dyed in the two spiral fabric tanks.

An axle distance adjustment device is provided for a conveyor-driven fabric dyeing machine and includes a conveyor belt in the form of an endless loop arranged inside a machine body and a fixed roller and a movable roller respectively arranged at two ends of the conveyor belt. The fixed roller has a rotary axle having two ends mounted through bearings to bearing seats mounted on sidewalls of the machine body. The movable roller has a rotary axle having two ends mounted through bearings to position-adjustable bearing seats, which are coupled to hollow bearing seat bases mounted to the sidewalls of the machine body. The position-adjustable bearing seats are attachable to the hollow bearing seat bases at different locations so that an axle distance between the rotary axle of the fixed roller and the rotary axle of the movable roller is changed for adjustment of tightness of the conveyor belt.

The embodiments of the present disclosure provide a composite yarn, a method and a device for processing the composite yarn, and protective equipment. The composite yarn comprises a core filament located at a core of the composite yarn; a first multifilament covering in parallel a peripheral surface of the core filament; a water-based adhesive distributed on a surface and inside of the first multifilament, wherein the water-based adhesive on the surface of the first multifilament forms a water-based adhesive layer; a second multifilament covering in parallel a peripheral surface of the water-based adhesive layer; and a single-clad structure layer or a double-clad structure layer covering an outer side of the second multifilament, wherein both the first multifilament and the second multifilament are organic multifilaments or inorganic multifilaments.

Reel for fabric treating machines, said reel comprising: a substantially cylindrical main body (110) having a side surface (111), a first axial end (112) and a second axial end (113); first and second flanges (114, 115), respectively mounted to the first and second axial ends (112, 113) of said main body (110); at least one drag element (120) mounted, in the operating position, externally to said side surface (111), at least one constraining device (130), associated with said drag element (120) to hold said drag element (120) in said operating position. The constraining device (130) can be switched between a first condition, in which it holds said drag element (120) in said operating position, and a second operating condition, in which it allows said respective drag element (120) to be removed.

A continuous process for the wet chemical treatment of fibers employs one or more squeezing/opening operations post chemical treatment to provide even chemical distribution on the fibers being processed. For squeezing the fiber batt impregnated with chemicals, one or more sets of squeeze rollers which include at least one roller with grooves are used to remove the liquid chemicals from the fiber batt efficiently. The squeezing operation can be coupled with the ability to collect and recycle chemicals for reuse in the chemical treatment process. The continuous process for the chemical treatment of fibers may employ the use of a blending box for the dried chemical-treated fibers in order to compensate for any uneven chemical distribution on fibers occurred during the chemical treatment process.
