Self-assembled functional layers in multilayer structures

Номер: US20120184165A1
Автор: Angelo Yializis, Gordon Goodyear
Принадлежит: Sigma Labs Inc

Functionalized multilayer structures are manufactured by a process whereby a substrate material is treated with a reactive-gas plasma to form an activated layer on the surface thereof, and then by depositing a liquid functional monomer on the activated layer to form a self-assembled functional layer. Any excess liquid monomer must be allowed to re-evaporate in order to obtain optimal functionality on the surface of the resulting structure. The deposition of the liquid layer is preferably carried out with high kinetic energy to ensure complete penetration of the monomer throughout the body of the substrate. For particular applications, prior to formation of the reactive layer the substrate may be coated with a high glass-transition temperature polymer or a metallic layer.

A nonwoven fabric is provided having a plurality of semi-crystalline filaments that are thermally bonded to each other and are formed of the same polymer and exhibit substantially the same melting temperature. The fabric is produced by melt spinning an amorphous crystallizable polymer to form two components having different levels of crystallinity. During spinning, a first component of the polymer is exposed to conditions that result in stress-induced crystallization such that the first polymer component is in a semi-crystalline state and serves as the matrix or strength component of the fabric. The second polymer component is not subjected to stress induced crystallization and thus remains in a substantially amorphous state which bonds well at relatively low temperatures. In a bonding step, the fabric is heated to soften and fuse the binder component. Under these conditions, the binder component undergoes thermal crystallization so that in the final product, both polymer components are semi-crystalline. 122-. (canceled)23.

A method for forming a biodegradable aliphatic-aromatic copolyester suitable for use in fibers is provided. In one embodiment, for example, an aliphatic-aromatic copolyester is melt blended with an alcohol to initiate an alcoholysis reaction that results in a copolyester having one or more hydroxyalkyl or alkyl terminal groups. By selectively controlling the alcoholysis conditions (e.g., alcohol and copolymer concentrations, catalysts, temperature, etc.), a modified aliphatic-aromatic copolyester may be achieved that has a molecular weight lower than the starting aliphatic-aromatic polymer. Such lower molecular weight polymers also have the combination of a higher melt flow index and lower apparent viscosity, which is useful in a wide variety of fiber forming applications, such as in the meltblowing of nonwoven webs.

A process for producing a nonwoven web material with improved edge quality, and the product thereof, are disclosed. The process may include the steps of forming a batt of polymeric fibers; consolidating the batt in a z-direction and thereby forming a nonwoven web material, conveying the nonwoven web material to a nip between a bonding roller and anvil roller, and impressing a pattern of bond impressions into the nonwoven web material, the bond impressions lying a long a cut path. When the web is subsequently cut along the cut path, fibers proximate the cut path are immobilized by the bonds, providing for relatively neater, cleaner cut edges and reducing the number of loose fibers that may be released into the plant environment in downstream processing operations.

The present invention provides a nonwoven fabric sheet for use in extraction filters having high sealing strength and extraction filters manufactured using the nonwoven fabric sheet. The nonwoven fabric sheet includes a first layer including a spunbonded nonwoven fabric formed from a polyester-based resin having an IV value of 0.60 to 1.00, a crystallinity of 30% to 80%, a crystalline orientation of 60% to 95%, and a birefringence (Δn) of 0.040 to 0.100 and provided with a partial thermocompression bonding section whose thermocompression bonding area rate is in the range of 5% to 30%, and a second layer including a meltblown nonwoven fabric formed from a polyester-based resin blown onto a surface of the first layer and solidified to have a crystallinity of 0% to 14%. The extraction filters are formed by sealing by welding the nonwoven fabric sheet with the second layer of the sheet placed inside. 1. A nonwoven fabric sheet comprising:a first layer including a spunbonded nonwoven fabric formed from fibers of a polyester-based resin having an IV value of 0.60 to 1.00, a crystallinity of 30% to 80%, a crystalline orientation of 60% to 95%, and a birefringence (Δn) of 0.040 to 0.100 and provided with a partial thermocompression bonding section having a thermocompression bonding area rate of 5% to 30%; anda second layer including a meltblown nonwoven fabric formed from fibers of a polyester-based resin blown onto a surface of the first layer and solidified, the polyester-based resin of the fibers forming the meltblown nonwoven fabric having a crystallinity of 0% to 14%.2. The nonwoven fabric sheet according to claim 1 , wherein:{'sup': '2', 'the spunbonded nonwoven fabric has a basis weight of 8.0 to 25.0 g/mand a fiber diameter of 10 to 40 μm;'}{'sup': '2', 'the meltblown nonwoven fabric has a basis weight of 2.0 to 10.0 g/m; and'}{'sup': '3', 'the nonwoven fabric sheet has a bulk density of 0.15 to 0.40 g/cm.'}3. An extraction filter formed by employing the nonwoven ...
