Disclosed is a napped artificial leather napped including: a non-woven fabric that is an entangle body of ultrafine fibers; and an elastic polymer impregnated into the non-woven fabric, the napped artificial leather having, at least on one side thereof, a napped surface formed by napping the ultrafine fibers, wherein the ultrafine fibers contain 0.5 mass % or more of a pigment (A), the elastic polymer contains 0 to 0.01 mass % of a pigment (B), and the ultrafine fibers and the elastic polymer are undyed; the napped surface has a lightness L* value of 25 or less in a color coordinate space (L*a*b* color space); and a ratio of an area occupied by the elastic polymer, observed on the napped surface, to a total area of an area occupied by the ultrafine fibers and the area occupied by the elastic polymer is 0.5% or less.

A printing apparatus includes a glue belt as an example of a transport belt including a support unit configured to support a medium, the support unit being configured to transport a medium by moving the support unit, a liquid ejecting unit configured to eject liquid onto a medium supported by the support unit, and a dyeing unit configured to perform dyeing by immersing a medium in dyeing liquid. Printing is performed on the medium by combining dyeing by the dyeing unit and ejecting by the liquid ejecting unit.

Method of treating a textile article by impregnation with a water dispersion of graphene nano-platelets in an impregnation bath comprising also a polymeric binder and an anti-migration and wetting agent. Graphene is fixed in the textile article to improve its thermal and electrical conductivity, as well as its filtering power and germ-blocking properties.

Disclosed is a knitted fabric containing natural fibers and a making method therefor, a liquid ammonia device and a shirt made from the knitted fabric, belonging to the fields of fabrics and clothing. The making method for the knitted fabric containing natural fibers comprises forming yarns containing natural fibers into a knitted fabric by a fabric-knitting method; and performing functional finishing including a liquid ammonia finishing procedure on the knitted fabric. In the liquid ammonia finishing procedure, liquid ammonia impregnation is performed on the knitted fabric at least twice under the condition of mechanical restraint by a guide roller set, thus preventing the knitted fabric from edge curling due to strong shrinkage in the liquid ammonia impregnation process, enabling the knitted fabric to be subjected to sufficient and uniform liquid ammonia impregnation, ensuring the liquid ammonia impregnation effect and controlling the shrinkage rate of the knitted fabric; and through subsequent shaping and finishing procedures, the color stability of the knitted fabric is further improved, the shrinkage rate after washing is reduced, and the crease-resistant performance and resilience performance are improved. The shirt has a low shrinkage rate after washing, good stiffness performance, good resilience performance, color stability, high strength and good crease-resistant performance.

A system and method for cationization of textiles preferably starting with the dry raw greige tubular or open width goods that are made from either a cellulosic or cellulosic blended fabric are described. The system can include an inducer apparatus with chemical dosification system. In a preferred embodiment, the dry tubular goods are sent in a flat configuration to a first impregnation tank where it receives a multi-functional reaction fluid. After leaving the first impregnation tank, the now wet fabric is turned (when in a tubular width fabric form) by a turning unit and then sent to a second impregnation tank where it again is exposed to the multi-functional reaction fluid. The turning of the fabric causes the side edge positions of the flat tubular fabric to change its physics dynamics which allows for the multi-functional reaction fluid to be evenly applied to the entire fabric. Turning is not needed for open with fabric as it is flat, thus having only one dynamic when analyzed with physics.
