Systems and methods for automated manufacturing of flexible goods and related technologies are disclosed. A workpiece can be processed to temporarily change its physical properties for facilitating handling and assembly operations. The system can include one or more automated handling apparatuses for transporting workpieces between workstations. Each workstation can perform a different stage of the manufacturing process. After the goods have been manufactured, the goods can be processed such that is returns to its original physical properties.

A pouch suitable for a white snus, wherein the white snus includes carrier material and nicotine without tobacco being present, includes a fabric, and a surface of the fabric is at least partially coated with an odorizing composition including tobacco particles having an average size ≤30 μm. A method for manufacturing a pouch for white snus includes the steps of providing fabric, providing an odorizing composition including tobacco particles having an average size ≤30 μm, coating at least parts of a surface of the fabric with the odorizing composition, forming a pouch from the fabric and filling a white snus composition in the pouch. The odorizing composition is an ink, preferably including a liquid and a coloring agent, wherein the liquid is preferably selected from a group including water, propylene glycol, and glycerin, propylene glycol, and glycerin.

An object of the present invention is to provide a fabric capable of easily and inexpensively forming a desired three-dimensional shape. The fabric according to the present invention contains an artificial protein fiber that contains a protein, in which the fabric has a surface including: a portion A that shrinks at a predetermined shrinkage rate when being brought into contact with water; and a portion B that has a shrinkage rate lower than that of the portion A when being brought into contact with water.

The present invention relates to a method for manufacturing a protein fiber, including an extension and contraction step of contracting or extending a protein raw fiber containing a protein by bringing the protein raw fiber into contact with a liquid or vapor; and a drying step of drying the protein raw fiber that has undergone the extension and contraction step while adjusting a length of the protein raw fiber to an arbitrary length.
