Abstract:
A hydrophilic binder fiber. These fibers may be produced by co-spinning a polyolefin core material with a highly wettable aliphatic polyester blend sheath material. The highly wettable aliphatic polyester blend comprises an unreacted mixture of an aliphatic polyester polymer selected from the group consisting of a polybutylene succinate polymer, a polybutylene succinate-co-adipate polymer, a polycaprolactone polymer, a mixture of such polymers, or a copolymer of such polymers; a multicarboxylic acid; and a wetting agent. The hydrophilic binder fiber exhibits substantially improved biodegradable properties, yet is easily processed. The hydrophilic binder fiber may be used in a disposable absorbent product intended for the absorption of fluids such as body fluids.
Abstract:
There is provided a conductive fiber capable of being sewn, woven or knitted, using conventional methods, into a conductive mesh for use with various wearable electronic devices and/or sensors that make direct contact with the skin. The conductive fiber, when combined with a non-slip fiber, facilitates comfortable electrical communication between different electronic devices and the skin.
Abstract:
The invention relates to a method for producing a foil of synthetic material composed of a first synthetic compound and a second synthetic compound, in which the first synthetic compound consists of a polymer and the second synthetic compound consists of a plastomer. The invention also relates to a synthetic fibre and to an artificial lawn suitable for sports fields, consisting of a substrate to which synthetic fibres according to the invention are fixed. Surprisingly, it has become apparent that when the fibres are according to the invention made from a combination of synthetic materials in which the first synthetic compound is a polymer and the second synthetic compound is a plastomer, the fibres will only exhibit a very minor any tendency to split, or even no such tendency at all, not even after stretching, also in the case of very intensive use in an artificial lawn. This renders the fibre very suitable for use in an artificial grass sports field, so that the field will not only require less maintenance but, in addition, will be capable of withstanding longer and more intensive use. Since the synthetic fibre—in addition to an improved splitting behaviour—exhibits strongly improved elastic and springing properties, the risk of injury and/or burns caused by slidings or falls is significantly reduced.
Abstract:
A bicomponent fiber comprising one thermoplastic polymer component comprising nonstarch, thermoplastic polymer and one thermoplastic starch component comprising a destructured starch and a plasticizer. The thermoplastic polymer component surrounds the thermoplastic starch component. Also provided are nonwoven webs and disposable articles comprising the bicomponent fibers.
Abstract:
The present invention comprises a binder fiber containing a metallocene catalyzed polyethylene (mPE) and an adhesion promoters. A web comprising the binder fiber and absorbent is also contemplated. The present invention also comprises a binder fiber containing polyolefin, an adhesion promoter, and an enhancement agent. The polyolefin may be polypropylene, high density polyethylene, medium density polyethylene, low density polyethylene, linear low density polyethylene, or ultra low density polyethylene, manufactured with either Ziegler-Natta or metallocene catalysts. A web comprising this binder fiber and absorbent is also contemplated. The adhesion promoter may be maleic anhydride grafted polyolefins, or ethylene-acrylic copolymers, or a combination of these. The enhancement agent may be one or more of titanium dioxide, talc, silica, alum, calcium carbonate, calcium oxide, and magnesium oxide.
Abstract:
A multi-structural filament comprises a single ingredient having two or more morphologies after extrusion through a die pack wherein one discrete region of the filament comprises one morphology of the ingredient and at least another discrete region of the filament comprises another morphology of the same ingredient, and wherein each region of the filament comprises at least about 7 percent of the filament. A process for the production of the filament is also described.
Abstract:
A side-by-side or eccentric sheath-core bicomponent fiber wherein each component comprises a different poly(trimethylene terephthalate) composition and wherein at least one of the compositions comprises styrene polymer dispersed throughout the poly(trimethylene terephthalate), and preparation and use thereof.
Abstract:
A stretchable synthetic polymer fiber comprising an axial core formed from an elastomeric polymer, and two or more wings attached to the core and formed from a non-elastomeric polymer, wherein preferably at least one of the wings is mechanically locked with the axial core. The fibers can be used to form garments, such as hosiery. A spinneret pack for producing such fibers is also provided.
Abstract:
A composition including an aromatic polyester and a copolyester having a lower melting point than the aromatic polyester. The aromatic polyester and the copolyester can be blended together to form fibers and fibrous webs. The composition can be thermally bonded at a temperature below the melting point of the aromatic polyester.
Abstract:
The present invention provides multicomponent fibers arranged in structured domains. At least one of the polymer components is formed of a multipolymer blend. The present invention also provides nonwoven fabrics formed of the multicomponent fibers, the fabrics having a superior combination of extensibility, tensile properties and abrasion resistance. A second layer can be laminated to this coherent extensible nonwoven web.
