A method is provided for operating an air spinning machine with a multiple number of spinning units, whereas each spinning unit has a spinning nozzle with an internal vortex chamber. The spinning nozzle is fed a fiber composite during the operation of the spinning unit. The spinning nozzle has a multiple number of air nozzles leading into the vortex chamber through which compressed air streams into the vortex chamber in order to generate a vortex air flow within the vortex chamber. The fiber composite receives a twist with the assistance of the vortex air flow within the vortex chamber such that a yarn is formed from the fiber composite. The air spinning machine features an additive supply, whereby an additive is at least temporarily fed a part of the spinning units. A liquid additive is used, whereas the additive is degassed prior to leaving the additive supply. In addition, an air spinning machine with a degassing device is described.

Composite fibers created by a process including vertically texturizing and impregnating resin into the fibers at controlled viscosity results in stronger fibers in which virtually no microbubbles are trapped resulting in improved tensile strength for use in reinforcing concrete and other materials.

A method of producing a hemp-blended single spun yarn may include: a fiber blending step of passing hemp fiber, together with latent and potential crimped yarn fiber, through an opener in order to increase the cohesion of the hemp fiber by the three-dimensional chain structure, thereby producing a blended fiber including 10% to 60% latent and potential crimped yarn fiber; a sliver production step of carding the blended fiber through a carding machine, and drafting the carded fiber through a drafting machine, thereby producing a sliver; and a spinning step of supplying the sliver as a roving yarn through a plurality of rollers to a twisting unit, and supplying a combined filament yarn, produced by combined twisting and having a structure in which a low-stretchability filament yarn surrounds a high-stretchability filament yarn, as a core yarn to the twisting unit without being passed through the plurality of rollers.

The present invention generally relates to the production of knitted caps that are lightweight and breathable. Generally, the manufacturing process for producing the knitted caps involves: (1) applying a continuous wax coating onto a polyester yarn; (2) twisting the yarn with one or more additional yarns to produce a twisted yarn; (3) knitting the twisted yarn into a knitted article; (4) sewing the knitted article into a headwear body; and (5) finishing the headwear body to form the headwear article. The resulting headwear articles can be in the form of caps that exhibit superior breathability and moisture wicking capabilities.

The present invention generally relates to the production of knitted sweatbands that exhibit superior elasticity and breathability. Generally, the manufacturing process for producing the knitted sweatbands involves: (1) applying a continuous wax coating onto a polyester yarn; (2) twisting the yarn with one or more additional yarns to produce a twisted yarn; (3) knitting the twisted yarn into a sweatband body; and (4) finishing the sweatband body to form the sweatband. The sweatbands of the present invention can easily facilitate the movement of sweat away from the wearer, while still providing comfort and breathability.

A distribution system for a wetting liquid supplied to spinning nozzles of an air-jet spinning machine includes a supply pipe for the wetting liquid supplied to the spinning nozzles. At least one UV light emitting diode is arranged in the supply pipe, wherein the UV radiation emitted by the UV light emitting diode passes through the wetting liquid to disinfect the wetting liquid.

A spinning unit of an air jet spinning machine with a spinning nozzle, which serves the purpose of producing a yarn from a fiber composite fed to the spinning nozzle. The spinning nozzle features an inlet for the fiber composite, an internal vortex chamber, a yarn formation element protruding into the vortex chamber along with an outlet for the yarn produced inside the vortex chamber. The spinning unit is allocated with an additive supply, which is designed to supply the spinning nozzle with an additive. The additive supply includes at least one top frame fixed on the spinning nozzle, through which the additive is able to be fed to the spinning nozzle. In addition, a top frame for fixing on a spinning nozzle of an air jet spinning machine is proposed.
