The invention relates to a fiber feed device (16) for a fiber blending unit (1) comprising a blending belt (15), by means of which fiber material (2) dropped onto the blending belt (15) from a bale opener (3) can be transported away, and comprising two guide walls (17, 18) arranged laterally to the blending belt (15) for guiding the fiber material (2) on both sides of the blending belt (15). According to the invention, the fiber feed device (16) comprises at least one rotary distributor (19) arranged over the blending belt (15), by means of which the fiber material (2) dropped onto the blending belt (15) can be distributed in the transverse direction of the blending belt (15) between the two guide walls (17, 18) by means of a rotational movement. The invention further relates to a fiber blending unit (1).

Disclosed are fibers which contain identification fibers. The identification fibers can contain a plurality of distinct features, or taggants, which vary among the fibers and/or along the length of the identification fibers, tow band, or yarn. The disclosed embodiments also relate to the method for making the fibers. Characterization of the fibers can include identifying distinct features, combinations of distinct features, and number of fibers with various combinations of distinct features and correlating the distinct features to supply chain information. The supply chain information can be used to track the fibers, fiber band, or yarn from manufacturing through intermediaries, conversion to final product, and/or the consumer.

A recycled fabric structure is provided, which includes a plurality of types of blended yarn arranged by weaving or interlacing. Wherein, each of the types of the blended yarn has a plurality of first fibers and a plurality of second fibers vertically arranged and interloped with each other. The plurality of first fibers accounts for 30% to 50% of the total weight of the blended yarn. The first fiber is a recycled fiber.

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.
