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.

An apparatus for manufacturing open carbon fiber superfine yarn comprises a yarn feeding part for feeding a carbon fiber bundle; a tank for storing water for opening carbon fiber to immerse the carbon fiber bundle in the water for opening carbon fiber; a first drying part for drying the open carbon fiber bundle formed by the immersion in the water for opening carbon fiber; an application part for applying a catalyst to the dried open carbon fiber bundle; a second drying part for drying the catalyst-applied open carbon fiber bundle to obtain open carbon fiber resin tape; a slitting part for slitting the open carbon fiber resin tape longitudinally; and a twisting part for twisting a plurality of the open carbon fiber resin tapes slit by the slitting part to form open carbon fiber superfine yarn.

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.

A segment roller (1) has a roller body (2), which is mounted rotatably about an axis (3). To this end, the roller body (2) has on the outside grooves (9), in which tongues (8) of profiles (7) engage. These profiles (7) grip the material web (5) directly or indirectly. In order to increase the working life and improve the mechanical properties of the profiles (7), the profiles (7) are of shear-resistant configuration and have elastic lips (20). These elastic lips (20) are deformed upon the engagement of the tongue (8) in the groove (9).

A method for improving the colourfastness of a dyed textile is provided. The method comprises the steps of: conveying a dyed textile along a processing line in a first direction; flowing a fluid from a reservoir through the dyed textile on the processing line in a second directly substantially opposite to the first direction; subsequently removing at least 50% of the applied fluid from the dyed textile; removing contaminants from the fluid; and returning the fluid to the reservoir.

A curl straightening method applied upon printing on a spread medium in a printing step, the method being provided with a first spreading step of spreading the medium fed out from a medium roll between a feeding step of feeding the medium from the medium roll in which the medium made of a textile fabric and having a predetermined width is wound on a roll core, and the printing step of printing on the medium fed out from the medium roll, and in the first spreading step, spreading of the medium is performed in a state where the medium fed out from the medium roll is stretched on an outer circumference of a first spreader roller rotating about a pivotal axis parallel to a pivotal axis of the medium roll, and the medium has its surface side with a curl stretched on the outer circumference of the first spreader roller.
