The present invention is directed to a method of making at least a portion of a garment that includes at least one three-dimensional contour. The disclosed method includes providing a fiber and solvent mixture that includes fibers and a solvent capable to causing a plurality of covalent bonds to be created between the fibers. In many embodiments, the plurality of covalent bonds form when a catalyst, such as heat, is provided to the fiber and solvent mixture. The process can be performed using, for example, either a 3D printer or mold form. The fibers used can be natural, synthetic, or a blend of natural and/or synthetic fibers. The solvent preferably includes ionic salts in water.

A fiber manufacturing apparatus includes: a fiber manufacturing portion including a first operation unit including a first operation surface and a second operation unit including a second operation surface facing the first operation surface, wherein at least one of the first operation unit and the second operation unit performs a reciprocating motion to manufacture a fiber between the first operation surface and the second operation surface; and a fiber collecting portion configured to collect the fiber manufactured between the first operation surface and the second operation surface, wherein at least one of the first operation surface and the second operation surface includes a polymer solution.

An oral hygiene composition includes a mixture of: (i) a carrier liquid; and (ii) a water-insoluble hydratable polymer fibers forming an entangled three-dimensional network of said water-insoluble hydratable polymer fibers in said carrier; wherein: said carrier liquid comprises one or more humectant in a concentration of total humectant in excess of 5 wt. % based on the weight of the composition; said composition has an elastic modulus G and a loss modulus G, and said elastic modulus G is larger that said loss modulus G; and said water-insoluble hydratable polymer fibers have a diameter of about 10 to about 20,000 nm and a length of at least 100 nm.

The invention addresses the problem of providing a cloth and a protective product that have lightweight properties, wearing comfort, and further protection performance against electric arcs. A means for resolution is a cloth including a spun yarn containing a meta-type wholly aromatic polyamide fiber, wherein the cloth has a lightness index L-value of 25 or less.

This invention relates to a Denim protective fabric, with fire-retardant properties, and the process of dyeing the warp with indigo blue dye on a mixture of cellulosic and synthetic fibers, in order to obtain a permanently fire-retardant fabric, resistant to flame, heat, breaking, tearing, cutting and abrasion by impact. The resulting fabric is also antistatic and can be considered as a protective fabric like fire-retardant Denim and also a multi-risk fabric. The indigo blue dye is applied on a mixture of cellulosic and synthetic fibers with permanently fire-retardant properties such as fire-retardant viscose, fire-retardant modal, modacrylic, polyacrylate, polyamide, polyester, antistatic carbon, para-aramid, meta-aramid, polyamide-imide, polyethylene, PBI, with the aim of obtaining an authentic Denim jeans fabric, with the characteristics of the tincture based on indigo blue dye that loses its color on rubbing, with use and washing.

The present invention relates to a method for manufacturing a shaped body comprising lignin which may be further processed into intermediate carbon fibers and finally also carbon fibers. Uses of said fibers are also disclosed. The present invention addresses the problem of lignin leaching into a precipitation bath. The solution to this problem is a novel method for minimizing the loss of lignin through the addition of certain salts into the precipitation bath.

Acid-resistant and biosoluble glass compositions and products made therefrom. The glass compositions exhibit acid resistance, durability in white water as may be used in a wet laid fabrication process, and good biosolubility. In another aspect, a glass fiber mat is made from such a glass composition, and may be used in the manufacture of lead-acid batteries, for example as a pasting material or battery separator.

A fiber assembly including fibrils including a fibril which is a part of a fiber extending in a direction of thickness of the fiber assembly and including a network structure formed with a binding portion resulting at least any from binding between fibrils and binding between a fibril and a fiber in at least any end portion in the direction of thickness of the fiber assembly and a liquid absorbent sheet-like article including the same as well as a fiber assembly which is excellent in diffusion of a liquid particularly at a surface and absorption thereof in the inside and includes fibrils and a liquid absorbent sheet-like article including the same as well as a method of manufacturing the fiber assembly can be provided.

Knit fabrics and military apparel such as T-shirts made therefrom are disclosed. The fabrics are constructed from blended yarns made from an intimate combination of nylon and cotton staple fibers. Such fabrics comprise a weight ratio of cotton to nylon which ranges from about 55:45 to about 85:15, and these fabrics also have a weight ranging from about 3 to about 8 oz/yd.sup.2. Knit fabrics of this type possess a desirable combination of good thermal protective properties, provided the specified high level of staple fiber blend uniformity is achieved, along with very useful abrasion resistance, bursting strength and drying time characteristics.

A three-dimensional lattice includes a stabilizing grid having grid warp strands and grid weft strands crossing the grid warp strands. Grid cells are defined by adjacent grid warp strands and adjacent grid weft strands intersecting the adjacent grid warp strands. A projecting net has net warp strands and net weft strands crossing the net warp strands. Each subnet in a plurality of subnets uniquely corresponds to a corresponding grid cell. Each subnet includes a net warp strand portion intersecting both of the grid weft strands that define the corresponding grid cell. Each subnet includes a net weft strand portion intersecting both of the grid warp strands that define the corresponding grid cell. The net warp strand portion and the net weft strand portion of each subnet are spaced from a minimum surface defined by the corresponding grid cell.
