A measuring device for measuring stickiness, imperfections and impurities in textile fibers, such a device includes a housing inside which a pair of rollers are placed, arranged side by side to one another and rotating in opposite senses and between which a web of cotton fibers is made to pass. The rollers are heated, the sticky fractions of the web that adhere to the rollers after the passage of the web between them are detected, and the sticky fractions adhering to the rollers are removed, wherein the heating is controlled by a processing and control unit as a function of the temperature of the rollers detected by a temperature sensor associated with them.

Method for making a cellulose-comprising, flame-resistant, textile article comprising multiple flame-retardant treatments. The method comprises: a. providing at least part of the textile article with a non-cellulose-reactive, phosphorous-containing, flame-retardant compound, and b. providing at least part of the textile article with a cellulose-reactive, phosphorous-containing, flame-retardant compound. The method is suitable for producing flame-resistant, textile articles such as flame-resistant garments. Said garments can be used to protect individuals from flames and/or heat.

In a cotton gin, water is sprayed into a duct transporting pneumatically conveyed cotton fibers from a gin stand toward a battery condenser to improve the operation of a bale press where the ginned fibers are compacted into a bale. In some embodiments, a taggant is incorporated into the water to mark cotton fibers so threads or fabrics made from the cotton can be identified for quality control purposes. Spray nozzles may deliver water droplets of roughly the same size as the diameter of the cotton fibers. The nozzles may be located on a duct in a location adjacent dead air in the duct to promote coverage of the spray onto the cotton stream. Air may be delivered around the nozzles into the duct to prevent buildup of cotton and debris around the nozzles.

A preparation method of a deodorizing nylon 6 fiber including providing a fabricating step of deodorizing nylon 6 chips and performing a spinning step. A porous powder of citrate is mixed with a caprolactam powder so as to obtain a raw material of a deodorizing chip. The raw material of the deodorizing chip is ground so as to obtain a size mixture of a deodorizing nylon 6. The size mixture of the deodorizing nylon 6 is polymerized so as to obtain the deodorizing nylon 6 chips. In the spinning step, a spinning material including the deodorizing nylon 6 chips is provided. The spinning material is spun so as to obtain a deodorizing nylon 6 fiber.

A vortex tube system for conditioning and blending fibrous material utilizing a helical inlet to the base of a central vortex tube, to condition and blend fibers in a fluidly conveyed stream, and to separate the fibers from debris, by abruptly changing direction of the conveying air flow. The vortex tube system for conditioning and blending combines the helical input with helical shaping of the air flow through the central vortex tube to induce greater dynamics which is continued at the top of the vortex tube through a separate drying chamber.

Describes a method for cotton mixes homogenization without categorizing bales in inventory, i.e., with no separation of bales into classes, whose main objective is to eliminate the large variability of cotton fiber quality for the spinning process resulted from data input concerning the quality of the mixes and inventories. With this method no categorization in inventory is required and more than 20 quality parameters can be controlled with no impact on the physical inventory management. The method is intended to solve problems in the production of cotton fibers relative to the variability among mixes, variability among the loads of the mixes and variability in the laydown of the bales resulting in cotton fiber with higher quality, as well this method presents an optimized logistics in the warehouse.
