Methods and apparatus for combating sick building syndrome include a plenum that is at least partially bounded by fabric comprising at least one naturally occurring botanically based, antimicrobial, morbidity-inducing fabric and preferably a fan for introducing air into the plenum for passage outwardly through the fabric thereby to cleanse the air of microbes contributing to sick building syndrome.

The method of manufacturing of the knitted fabric finished with amber finish consisting of the six stages of preparation, bleaching, rinsing, drying, padding bath and final drying. Raw knitted fabric is delivered to the process and prepared for bleaching; next - the knitted fabric is being bleached, preferably in dyeing machine of MCS FIRST type at the temperature close to boiling point of water, preferably at 95°C. During the process of bleaching, a bleaching liquor is applied, where water is used as a carrier of bleaching agents. Bleaching agents are some or all additives falling within the group: hydrogen peroxide solution, caustic soda, stabilizer for hydrogen peroxide solution having a composition and/or properties of SOF FLU preparation, preferably SOF FLU preparation itself, dispersing soap, preferably isol dispersant S40, anti-foam agent having a composition and/or properties of Anchemol P preparation, preferably Anchemol P preparation itself, softening agent and an agent reducing surface tension of the bath and having a composition and/or properties of Softan PE preparation, acetic acid. After completion of bleaching operation, the knitted fabric is being rinsed and dried. Preferably, the drying temperature amounts to about 145°C, whereas the fabric advance speed equals to 10m/min. After drying to the required level of humidity, the knitted fabric passes through the amber padding bath with a squeeze of 60 up to 90%. Preferably, the above is carried out in the apparatus of FULARD type. Besides the dissolved amber, the bath liquor contains also resin having a composition and/or properties of Holiavkiran FEOO preparation and/or bonding hardener having composition and/or properties of Isol thiener PDN. After passing through the padding bath, the knitted fabric reaches the dryer. Preferably, the temperature of drying equals to about 140°C, whereas the fabric advance speed equals to 10m/min.
摘要:
Die modernen Kunstfasern aus aromatischen Polyamiden haben eine außerordentlich hohe Zugfestigkeit und würden sich daher sehr gut für hochbelastbare Seile eignen, wenn man ihre Zugfestigkeit voll ausnützen könnte. Wegen der glatten Faseroberfläche dieser Kunstfasern macht aber die Übertragung entsprechend hoher Zugkräfte auf solche Kunstfaserseile große Schwierigkeiten, denn aus Klemmhülsen und anderen auf Haftreibung beruhenden Kraftübertragungsmitteln rutschen sie vor Erreichen ihrer Reißfestigkeit heraus, und Versuche mit kunstharzgetränkten Seilen führten zwar zu den gewünschten Kraft- übertragungseigenschaften, jedoch unter Verlust der für Seile unverzichtbaren Flexibilität. Dieses Problem wurde dadurch gelöst, daß zur Tränkung ein Material verwendet wird, das bei die Bruchgrenze des Materials überschreitenden Druck- und/oder Biegebeanspruchungen im Beanspruchungsbereich in Pulver zerfällt. Besonders geeignet hierfür sind Naturharze, insbesondere Kolophonium. Das Diagramm in Fig. 3 zeigt die spezifische Belastbarkeit solcher Kunstfaserseile in Abhängigkeit vom Verhältnis der Klemmhülsenlänge zum Faserbündeldurchmesser für ungetränkte, kunstharzgetränkte und naturharzgetränkte Seile und verdeutlicht, daß von den gezeigten Beispielen nur die Naturharztränkung eine volle Ausnützung der Zugfestigkeit der Fasern zuläßt.
摘要:
A novel composition of crude tamarind kernel powder (TKP) is disclosed. The novel composition results from a process which makes TKP soluble in cold water; this process is not dependent on purification of TKP, but involves dissolving it in hot water and evaporating the resulting solution. The novel TKP composition has utility in textile, paper, and oilfield applications.
摘要:
A method of marking fibers, wherein the method includes providing a plurality of fibers; depositing a marker onto at least a portion of the fibers, the depositing being performed with a delivery mechanism comprising one or more outlets; and thereby marking the fibers. Also provided is a device for marking fibers, including a transport system adapted to transport fibers in a direction of a marker delivery apparatus positioned along the transport system; the delivery apparatus includes one or more outlets, adapted to deposit a solution of the marker through the outlets onto at least a portion of the fibers; and thereby marking the fibers. Authentication of a fibrous material using the marking method of the invention followed obtaining a sample of the marked fibers and assaying the sample for the presence of the nucleic acid marker; and thereby determining whether the fibrous material is authentic or counterfeit.
