Durable hydrophilic compositions comprising aliphatic polyester, an anionic surfactant, and in some embodiments, a carrier.

A yarn or thread may include a plurality of substantially aligned filaments, with at least ninety-five percent of a material of the filaments being a thermoplastic polymer material. Various woven textiles and knitted textiles may be formed from the yarn or thread. The woven textiles or knitted textiles may be thermal bonded to other elements to form seams. A strand that is at least partially formed from a thermoplastic polymer material may extend through the seam, and the strand may be thermal bonded at the seam. The woven textiles or knitted textiles may be shaped or molded, incorporated into products, and recycled to form other products.

A partially degradable polymeric fiber includes a thermally degradable polymeric core and a coating surrounding at least a portion of the core. The thermally degradable polymeric core includes a polymeric matrix including a poly(hydroxy-alkanoate), and a metal selected from the group consisting of an alkali earth metal and a transition metal, in the core polymeric matrix. The concentration of the metal in the polymeric matrix is at least 0.1 wt %. The partially degradable polymeric fiber may be used to form a microvascular system containing one or more microfluidic channels.

Multi-filament polyamide yarns characterized by high tenacity and low shrinkage are disclosed. Such yarns or fabrics made therefrom can be used in industrial applications in which such a combination of properties is desirable. Such yarns are particularly useful in the manufacture of automobile airbag fabrics. Also disclosed is a process for making such yarns. The yarn manufacturing process involves spin-drawing molten nylon, relaxing and controlling the yarn tension, and then winding the yarn. Yarns made according to this process exhibit linear density in the range of 110-940 decitex, tenacity equal to or greater than 80 cN/tex, and shrinkage, measured at 177 C., of less than 5%.

Woven fabrics are formed from high tenacity fibers or tapes that are loosely interwoven with adhesive coated filaments, to composite articles formed therefrom, and to a continuous process for forming the composite articles.

A pre-saturated wiper for use in a cleanroom environment, or other similarly controlled environment, that includes a woven fabric which incorporates a unique weave pattern with sealed edges that is saturated with only Ultrapure water (UPW).

A pre-saturated wiper for use in a cleanroom environment, or other similarly controlled environment, that includes a woven fabric comprised of two separate and distinct microfiber materials which incorporates a unique weave pattern with sealed edges that is saturated with only Ultrapure water (UPW).

This invention relates to a hybrid fabric comprising at least one structural fiber having a first melting temperature range and at least one thermo-formable fiber of having a second melting temperature range which is lower than the first melting temperature range to such an extent that the structural fiber does not melt in the second melting temperature range of the thermo-formable fiber. The hybrid fabric comprises (1) a first network comprising the structural fibers, (2) a second network comprising the thermo-formable fibers, the thermo-formable fibers comprising non-relaxed fibers made of a thermoplastic material, and (3) a plurality of openings between the fibers of the first and second network. The structural and thermo-formable fibers of respectively the first and second network interpenetrate one another and are connected to each other over at least part of the first and second network at a plurality of knot positions in the fabric where the structural and thermo-formable fibers are interwoven.

Ballistic resistant materials and articles formed from fiber/tape plies that incorporate multiple different fiber or tape types within a single ply. The different fiber or tape types are physically dissimilar but may be chemically different or substantially chemically similar.

Binder compositions are described, where the compositions include a protein, a first crosslinking compound that includes a carbohydrate, and a second crosslinking compound that includes two or more primary amine groups. The first and second crosslinking compounds may be individually crosslinkable with each other and with the protein. Also described are fiber products that may include inorganic or organic fibers and a cured thermoset binder prepared from a protein and at least two crosslinking compounds. Additionally, methods of making fiber products are described that include providing inorganic or organic fibers, and applying a liquid binder composition to the fibers to form a fiber-binder amalgam. The liquid binder composition may include a protein and at least two crosslinking compounds that include a carbohydrate and an organic amine with two or more primary amines. The amalgam may be heated to a curing temperature to form the fiber product.
