An apparatus is provided for producing nonwovens. The apparatus includes a card drum that is rotatable in a first direction of rotation, a transfer cylinder that is rotatable in a second direction of rotation opposite to the first direction of rotation, at least one doffer, at least one condenser, at least one stripper roll, a first endless conveyor belt, a suction drum and a second endless conveyor belt.

A spinning preparation machine includes a consolidating means for producing a roving having a protective twist from a fiber bundle, a drafting system arranged upstream of the consolidating means, a winding device arranged downstream of the consolidating means, and a movably mounted traversing element adjacent the winding device to guide the roving being wound onto a tube. In a side view of the spinning preparation machine, the consolidating means is arranged vertically between at least one feed roller of the drafting system and the traversing element, and the feed roller and the traversing element are arranged on a same side of the consolidating means so that in operation of the spinning preparation machine, the roving experiences a change in direction after exiting the consolidating means and prior to being wound onto the tube.

A card wire has consecutive teeth spaced apart in the longitudinal direction by a pitch. The teeth are bounded in the longitudinal direction by a tooth face on a first side and by a tooth back on a second side. Looking downwards in the height direction of the card wire, the tooth face and the tooth back of consecutive teeth merge in a tooth base and, looking upwards in the height direction, form a tooth tip. The tooth depth is defined by the greatest distance, in the height direction of the card wire, from the tooth tip to the tooth base. The ratio of pitch to tooth depth is less than 1.1. An interspace, measured at right angles to a tangent to an inflection point between tooth back and tooth base, between this inflection point and the opposite tooth face is greater than a quarter of the pitch.

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.
