A fiber powder having a 50% particle diameter (d.sub.50) of 6 to 60 μm, characterized in that the fiber powder has a maximum particle diameter (d.sub.100) of 1,000 μm or less. It is preferred that a value ((d.sub.10.Math.d.sub.90)/d.sub.100) obtained by dividing by the maximum particle diameter (d.sub.100) a value which is obtained by multiplying a 10% particle diameter (d.sub.10) by a 90% particle diameter (d.sub.90) is 0.3 to 5.0, that the fiber powder has an extractable component content of 0.2 to 3.0% by weight based on the fiber weight, and that the fiber powder has a water content of 0.2 to 50% by weight. Further, it is preferred that the fiber powder is an organic material, or comprises a thermoplastic resin, and that the thermoplastic resin is a polyester resin or a polyamide resin.

An adjustable protective face covering having a first end having one or more openings spaced apart there along and a second opposing end having one or more openings spaced apart there along. A length extends therebetween for covering a mouth and nose of a wearer, and the face covering is a single use face covering that is a constructed from a unitary sheet comprised of surgical wrap, polypropylene, Spunbond Meltblown Spunbond (SMS), or cotton. The single component mask can be cut from sheets of substrate using various techniques including laser cutting, die cutting, or other machinery typically of use in clothing manufacture.

A manufacturing frame comprises one or more alignment tabs. Each alignment tab comprises an alignment element. The alignment element interacts with a corresponding alignment element at a manufacturing station to identify to the manufacturing station the position and orientation of the frame. The frame supports a flexible material in a known position and orientation relative to the frame, allowing the manufacturing station to infer the position and orientation of the flexible material on the frame from the interaction of the alignment elements on the frame and the manufacturing station.

The invention relates to a die for cutting a shape or pattern from a material, the die being composed of a base plate (1) comprising an upper surface (2) and a lower surface (3). The die comprises one or more raised edges (4) in the form of a pattern or shape to be die-cut or embossed, on each of the upper and lower surfaces, such that the die can be used to die-cut or emboss two sheets of material simultaneously.

An aspect of the present invention provides a raw fabric cutting device. The device comprises: a support portion for supporting a raw fabric; a compressing portion for evacuating the space between a cover arranged on the raw fabric and the support portion such that the raw fabric is compressed; a cutting portion transferred above the support portion so as to cut the raw fabric; and a sealing portion transferred together with the cutting portion and configured to supply a sealing member to an open area of the cover, which is exposed as the raw fabric is cut, thereby covering the open area, wherein the sealing portion comprises a sealing member cutting portion for forming a notch on at least one side of the sealing member in the transverse direction with regard to the direction of transfer of the sealing member.

A device for measuring and cutting soft materials, wherein the device has a lower section and an upper section, the lower section having a bottom surface and a top surface, and at least one opening extending from the top surface to the lower surface. Bendable means on the upper section, and at least one piercing object carried by the bendable means, wherein the bendable means bends in response to a downward force applied to it, causing the piercing means to move through the opening and engage the soft material, said bendable means being self-retracting so that it returns to a natural resting position when the force ceases to exist, causing the piercing object to disengage from the soft material.
