Methods for increasing biocidal activity of a substrate are provided. The methods can include attaching one or more ionic compounds to the substrate. The ionic compound can include a cationic moiety and at least one of an N-halamine precursor group or an N-halamine moiety.

A fabric for thermal management including the cooling of an object, such as a person's skin. The fabric is formed of a plurality of functional zones arranged to extend the period of cooling without the use of artificial cooling chemicals. The functional zones include one or more of three different functional zone types. The first type diverts moisture. The second type retains and stores moisture. The third type absorbs moisture. One of the functional zones may be punched to create perforations to provide fabric flexibility and to assist in liquid diversion from within the fabric. An anchor system facilitates retention of the fabric on the object.

Provided herein are seam tapes and related methods. The seam tapes can be compatible with polyolefin-based waterproof/breathable (w/b) membranes, including polypropylene (PP) w/b membranes and/or polyethylene (PE) w/b membranes. Also provided are seams sealed by means of these seam tapes, as well as materials, fabrics, and garments including one or more of these sealed seams.

Unique blends of fibers that incorporate synthetic cellulosic fibers to render fabrics made with such blends more durable than fabrics made with natural cellulosic fibers such as cotton. While more durable than cotton, the synthetic cellulosic fibers used in the blends are still inexpensive and comfortable to the wearer. Thus, the benefits of cotton (affordability and comfort) are still attained while a drawback of cottonlow durabilityis avoided. In one embodiment, the fiber blend includes FR modacrylic fibers and synthetic cellulosic fibers, preferably, but not necessarily non-FR lyocell fibers such as TENCEL and TENCEL A100. Other fibers may be added to the blend, including, but not limited to, additional types of inherently FR fibers, anti-static fibers, anti-microbial fibers, stretch fibers, and/or high tenacity fibers. The fiber blends disclosed herein may be used to form various types of FR fabrics. Desired colors may be imparted in a variety of ways and with a variety of dyes to the fabrics disclosed herein. Fabrics having the fibers blends disclosed herein can be used to construct the entirety of, or various portions of, a variety of protective garments for protecting the wearer against electrical arc flash and flames, including, but not limited to, coveralls, jumpsuits, shirts, jackets, vests, and trousers.

Novel absorbable polymer blends are disclosed. The blends are useful for manufacturing medical devices having engineered degradation and breaking strength retention in vivo. The blends consist of a first absorbable polymeric component and a second absorbable polymeric component. The weight average molecular weight of the first polymeric component is higher than the weight average molecular weight of the second polymeric component. At least at least one of said components is at least partially end-capped by a carboxylic acid group. Further aspects are medical devices made therefrom.

Biocidally active cationic analogs of N-halamine having two biocidally active groups covalently bonded together in a single molecule and having general Formula (I). Compounds of Formula (I), and precursurs thereof, can be in solution form or immobilized onto a substrate via physical coating or covalent chemical bonding to functionalize surfaces or added into materials as additives so as to render them biocidal. The biocidal solutions and substrates comprising the compounds or precursors of the present invention can then be used to inactivate pathogenic microorganisms.

The present invention provides preparation of a yarn with coffee residue. The present invention also provides a novel yarn with coffee residue and applications of the same.

The invention relates to a planar structure for joining, in particular for the material-uniting joining, of at least two components. According to the invention, the planar structure is flexible and formed by at least one reaction strand. The reaction strand comprises a preferably cylindrical core, which is provided, at least in some areas, with a coating, which is constructed with a plurality of coaxially applied layers with a small thickness. To produce the layers, two different materials are used, the layers being constructed alternately with one of the two materials. Because of the high degree of flexibility of the reactive planar structure and its arbitrary area extent, components with a complex geometry in the region of the joint faces as well as large-format components can be joined in a material-uniting manner without problems. The reactive planar structure can be produced here using the methods known from textile engineering with virtually any dimensions and, in addition, by a continuous industrial production process. Moreover, the invention relates to a method for providing a material-uniting connection between two components, in particular by means of the planar structure according to the invention.

The disclosure relates to composite nonwoven fibrous web including an embedded phase having a population of particulates forming a substantially continuous three-dimensional network, and a matrix phase comprising a population of fibers forming a three-dimensional network around the particulates. The disclosure also relates to methods of making a composite nonwoven fibrous web including forming an embedded phase having a population of particulates in a substantially continuous three-dimensional network, and forming a matrix phase comprising a population of fibers forming a three-dimensional network around the particulates. Articles made from a composite nonwoven fibrous web prepared according to the methods as described above are also disclosed. In exemplary embodiments, the articles may include gas filtration articles, liquid filtration articles, sound absorption articles, surface cleaning articles, cellular growth support articles, drug delivery articles, personal hygiene articles, and wound dressing articles.

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.
