摘要:
This invention relates to patterned conductive textile sensors such as those for simultaneously measurement of strain, temperature and relative humidity. The patterned textile structures comprise sensing elements of various electrical conductivity and they are in the forms of fabrics, fibres, filaments or yarns coated with conductive polymers.

An antimicrobial composition comprising an organic antimicrobial component (K) and at least one metal salt component (M) and also, where appropriate, a solvent (L) and further auxiliary components, which comprises as organic component (K) at least one compound of the general formula (I) where the radicals independently have for example the following meanings: R1 is a branched or unbranched alkyl radical having 1 to 12 carbon atoms, R2 is a branched or unbranched alkyl radical having 1 to 12 carbon atoms, R3 is a branched or unbranched alkyl radical having 1 to 12 carbon atoms, R4 is a branched or unbranched alkyl radical having 1 to 18 carbon atoms, R5 is a branched or unbranched alkyl radical having 1 to 18 carbon atoms, R6 is a branched or unbranched alkyl radical having 8 to 18 carbon atoms; n is an integer from 1 to 6, and which comprises as metal salt component (M) at least one salt of a di- to pentavalent metal, is useful for durable finishing of textiles.
摘要:
Fabrics are made electrically conductive by contacting the fabric under agitation conditions with an aqueous solution of a pyrrole or aniline compound, and an oxidizing agent and a doping agent or counter ion; and then epitaxially depositing onto the surface of the individual fibers of said fabric the in status nascendi forming polymer of the pyrrole or aniline compound so as to uniformly and coherently cover the fibers with an ordered conductive film of the polymerized pyrrole or aniline compound. Individual fibers and yarns can be similarly treated and then formed into fabrics. Products made by the process are also described.
摘要:
Flame retardant, shaped materials comprising a vinyl polymer of crosslinked structure containing in its vinyl units 40 mole-% or more based on the polymer of COOH groups which have been partly converted to COOM (M: a mono- to tri-valent metal) groups, the COOM group content of said polymer being preferably 0.5 to 40 % by weight in terms of metal content.
摘要:
Bonded fibrous nonwoven textile fabrics having excellent strength and textile-like softness, drape and hand which are intermittently bonded with synthetic resins in predetermined print patterns of binder areas having a relatively high, uniform concentration of from about 50 to about 120 percent by weight of resin binder in the binder areas, based on the weight of the fibers therein, said binder areas having very sharply defined borders or edges with a minimum of binder feathering thereat whereby the optical density of the bonded fibrous nonwoven textile fabric very sharply increases from substantially zero to a maximum of at least from about 0.6 to about 1.0 or greater in a distance of less than about 1 mm. (0.04 inch), and methods of depositing such synthetic resins from colloidal aqueous dispersions thereof onto wet fibrous webs to form the bonded fibrous nonwoven textile fabrics, comprising the use of (1) metal complex coordination compounds and (2) synthetic resins and/or surfactants, at least one of which contains a specific coordinating ligand capable of being affected by ions of said metals to control the total migration of the resin binder during such deposition.
摘要:
AN IMPROVED PROCESS IS PROVIDED FOR THE FORMATION OF FIBROUS MATERIALS OF ENHANCED THERMAL STABILITY DERIVED FROM ACRYLIC POLYMERS CONSISTING PRIMARILY OF RECURRING ACRYLONITRILE UNITS. A MINOR QUANTITY OF A LEWIS ACID CAPABLE OF PROMOTING THE CYCLIZATION OF PENDANT NITRILE GROUPS IS INCORPORATED IN A SOLUTION OF THE ACRYLIC POLYMER, A CYCLIZED ACRYLIC MATERIAL IS FORMED WITHIN THE SOLUTION AT AN ELEVATED TEMPERATURE, THE RESULTING SOLUTION IS SPUN TO FORM A CYCLIZED ACRYLIC FIBROUS MATERIAL WHICH IS SOLUBLE IN,N-DIMETHYLFORMAMIDE, AND THE RESULTING CYCLIZED ACRYLIC FIBROUS MATERIAL IS HEATED IN AN OXYGENCONTAINING ATMOSPHERE UNTIL A STABILIZED FIBROUS PRODUCT IS FORMED WHICH IS CAPABLE OF UNDERGOING CARBONIZATION AND WHICH IS INSOLUBLE IN N,N-DIMETHYLFORMAMIDE. THE STABILIZED FIBROUS MATERIAL MAY NEXT OPTIONALLY BE CARBONIZED OR CARBONIZED AND GRAPHITIZED AT ELEVATED TEMPERATURES WHILE PRESENT IN AN INERT ATMOSPHERE.

AN IMPROVED PROCESS IS PROVIDED FOR THE FORMATION OF FIBROUS MATERIALS OF ENHANCHED THERMAL STABILITY DERIVED FROM ACYRLIC POLYMERS CONSISTING PRIMARILY OF RECURRING ACRYLONITRILE UNITS. A MINOR QUANTITLY OF A LEWIS ACID CAPABLE OF PROMOTING THE CCLIZATION OF PENDANT NITRILE GROUPS IS INCORPORATED IN A SOLUTION OF THE ACRYLIC POLYMER AND A CYCLIZED ACRYLIC MATERIAL IS FORMED THEREIN WHICH IS SUBSEQUENTLY SPUN INTO A FIBER WHICH EXHIBITS NO APPRECIABLE EXOTHERMIC REACTION WHEN HEATED TO 500* C. UPON SUBJECTING THE RESULTING FIBER TO RELATIVELY MILD PREOXIDATION CONDITIONS A STABILIZED FIBROUS MATERIAL MAY BE FORMED WHICH OPTIONALLY MAY BE CARBONIZED OR CARBONIZED AND GRAPHITIZED AT ELEVATED TEMPERATURES WHILE PRESENT IN AN INERT ATMOSPHERE.
摘要:
A new composition of an emulsion polymerized resin and certain metal salts, wherein the metal ion has a valence of at least 3; and a method of controlling resin deposition on materials by pretreating the materials whereby they have an alkaline condition and by applying the new composition to the material under alkaline conditions.
