This invention relates to a method of manufacturing a superabsorbent polymer fiber and a superabsorbent polymer fiber manufactured thereby.

A seed cotton dryer comprises an array of electromagnetic wave energy generators in a cotton gin, a cotton picker/stripper. An appropriate amount of energy is used to evaporate a considerable amount of moisture in the seed cotton without producing enough energy to pop the cotton seeds. Seed cotton dried by wave energy is much easier to separate the cotton seeds and lint from leaves, stems and other plant parts. The seed cotton is preferably transported through the dryer in a conduit having flat sides which reflects the wave energy more efficiently than through a round conduit. Provisions are made to prevent arcing in the transport conduit when extraneous metal pieces are inadvertently mixed with the seed cotton. In some embodiments, heated air from a diesel engine is used to dry crops as they are being harvested.

Disclosed are a method for preparing spun leather yarn using leather fiber, and spun leather yarn prepared according to the preparation method. The spun leather yarn prepared according to the preparation method enables the manufacture of fabrics, knitted goods, and lace goods, which have the character of leather, and thus can be effectively used for various fashion applications. In addition, the spun leather yarn can replace existing leather materials, which have been used in bags, athletic shoes, and the like, and thus is not affected by material supply in accordance with seasonal changes, and accordingly, the economic effect thereof is excellent. Moreover, the spun leather yarn has warmth retention and general flame retardancy, which are the properties of natural leather, and thus is of very high quality.

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.

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.

Biocompatible coatings and spin finishes that can be applied to polyhydroxyalkanoate (PHA) polymers, and medical devices made from PHA polymers, have been developed. The coatings impart good lubricity to PHA polymers, particularly to fibers and braids made from these materials, making the coatings ideal for use on medical devices such as PHA braided sutures. The spin finishes can be applied to PHA fibers to facilitate their manufacture, and also for their conversion to other products, including medical textiles. The spin finishes serve to protect multifilament fiber bundles, and keep them intact following extrusion, and also to impart lubricity to the fiber bundles and monofilament fibers so that they are not damaged in subsequent processing steps particularly in textile processing. The coating reduces tissue drag of, for example, braided sutures.
