Description

200837241 IX. Description of the invention: [Technical field to which the invention pertains] [Prior Art] Elastic materials are widely used in various applications, including belt linings, medical wraps and bandages, and functional dressing materials. Elastic materials have advantages over non-elastic products, including their comfort for body structure and movement, such as belt applications and medical wraps. In addition, when the elastic material is used in a medical wrap or bandage, it is applied to the injured or injured area to provide medical comfort. In medical wraps or bandage applications, in order to accelerate the efficacy, the elastic material also needs to be breathable so that oxygen can be transported to the injured area and the water vapor and other gases escape from the injured area, and the absorption of blood and wound secretions It can be removed from the injured area by direct contact with the bandage. Absorptive force is also required when the elastic material is filled with topical ointments and other treatments such as anesthetics and subsequent treatment dressings. For apparel applications such as belt linings or embroidered base fabrics, the advantage of elastomeric materials is that they can be converted into yarn-forming, have high tensile strength and can be re-washed and applied dry-cleaning procedures without damaging or losing their elastic properties. Another feature of this product is that it must not decrease or only decrease in length in the CD direction when it is stretched in the MD direction. This is especially important in apparel applications where some of the materials used in the prior art tend to reduce the length in the transverse direction when stretched, causing the waistband to be distorted. Usually when the material is extended in one direction, it tends to be thinner in the other two directions (described by the material's Poisson ratio). Elastic materials with some or all of these qualities can be used in these areas: garment lining, medical 200837241 wraps and bandages, or functional dressing. However, it is practical to provide elastic materials with some or all of these qualities. For example, due to the limited elastically retractable stretch of non-woven fabrics, the garment industry resorts to expensive belts such as woven fabrics that use 45 degree twill cuts, or the use of knits, or the use of webs containing continuous elastomeric fibers, or the use of elastomeric films. Or use a variety of microgrids, or apply a complex waistband design that allows for overlapping overlapping fiber sections. In medical wraps or bandage applications, attempts have also been made to impart resilience, breathability and strength to resilient elastomeric materials. In addition to being woven into the elastic material layer or fibers, the stretching of the nonwoven web can be recovered, and the other methods are non-woven fabric treatment or micro-twisting treatment. During processing, the nonwoven web is attached to a total surface and removed from the surface using a doctor blade. Upon micro-twisting, as it moves over or removes from the roller, the retractable extension of the nonwoven web is achieved by retarding and compressing the web. However, 'various application markets continue to look for suitable recyclable extended non-woven materials' that combines other desirable application characteristics and maintains cost-effectiveness with simple production processes. SUMMARY OF THE INVENTION Definition of bicomponent fiber or filament: extruding a polymer source from a separate extruder and simultaneously spinning to form a single bundle of fibers or filaments, thereby forming a composite fiber or length wire. Two different polymers are typically extruded, although bicomponent fibers or filaments may comprise compacts extruded from different extruders of the same polymeric material. The polymer extruded -6-200837241 is arranged substantially in a distinct zone across the cross-section of the bicomponent fibers or filaments and extends substantially continuously along the length of the bicomponent fibers or filaments. The structure of the bicomponent fibers or filaments may be symmetrical (e.g., sheath-core or side-by-side) or asymmetrical (e.g., sheath-type lithography; the whole is circular and the fibers are crescent moon patterns). The ratio of the two polymer sources can be, for example, but not absolute, 7 5/25, 5 0/5 0, 25/75. A bicomponent fiber (b i c ο n s t i t u e n t f i b e r ): a fiber formed by mixing two or more polymers extruded from the same spinning nozzle. The bicomponent fibers do not have a plurality of polymer compositions arranged in a distinct region that is relatively transverse to the cross-sectional area of the fibers, and the plurality of polymers are generally not continuous along the total length of the fibers, and fibril formation typically begins and ends randomly. Double-component fibers are sometimes referred to as multi-component fibers. Calendering (c a 1 e n d e r i n g ): a process for pressing the surface of a non-woven material between opposing surfaces. The opposite surface contains a flat platen and a roller. Any or both of the opposing surfaces can be heated. Any one or both of the opposing surfaces may include protrusions. Cellulosic material: A material that substantially contains cellulose. Cellulose fibers are derived from artificial sources (e.g., regenerated cellulose fibers or lyocell fibers) or natural sources such as fibers or wood and non-woody plant pulp.

Hydraulic entanglement (H y d r 〇 e n t a n g 1 e m e n t): Fine, high-pressure water jet is used to stagger the non-woven fibers. Hydraulic entanglement is known as water weave (s p u η 1 a c i n g ), and by arranging the jet stream, various aesthetic effects can be obtained. The water column pressure used is usually directly related to the strength of the net, but the system design also plays an important role. Non-woven webs of different characteristics can be hydraulically entangled to create non-woven composites that are difficult to achieve different grades by other means. Lyocell: A man-made cellulosic material obtained by directly dissolving cellulose in an organic solvent without forming an intermediate product, followed by extruding a cellulose solution and an organic solvent into a coagulation bath.

Conifers include, for example, cedar, fir, hemlock, pine and spruce. S p u n b ο n d f i 1 a m e n t: a filament formed by extruding a molten thermoplastic material from a plurality of fine, usually annular, capillary die-spinning nozzles. The radius of the extruded filaments can be rapidly reduced by, for example, eductive drawing and/or the well known spunbonding mechanism. The spunbond fibers may have a single niger range of from about 1 to 5 or more and are substantially continuous from one end of the nonwoven web to the opposite end. -11- 200837241 Spunbond nonowoven web: (usually) extruding at least one molten thermoplastic material from a plurality of fine, usually annular, capillary nozzles in a single process as a plurality a net formed by filaments. The filaments are partially repelled and then stretched to reduce the fiber's Danny's and increase the molecular orientation of the fibers. The filaments are generally continuous and non-tacky when they are deposited on the collecting surface as fibrous batt. The fibrous batt is then bonded by, for example, thermal bonding, chemical bonding, mechanical pin rolling, hydroentangling, or a combination thereof to produce non-woven fibers. Staple fiber: A fiber (0.66 to 20 cm) formed or cut into a fiber length of usually 1/4 to 8 inches.

The achievement and / or the purpose of the invention is not necessary. As used herein, "about" means that the quantity or state correction may exceed its disclosure as long as its disclosure advantage is understandable. The invention can be better understood by the following detailed description, drawings, and embodiments of the invention. [Embodiment] ® In one embodiment, the elastic composite nonwoven material comprises a first wet-formed nonwoven fibrous portion applied to a second nonwoven fibrous substrate. The second nonwoven substrate is a pre-bonded web such as a carded knit web, a spunbond web or a carded hydroentangled web (generally referred to as water weave). The nonwoven base mesh may have a basis weight of from about 15 to about 150 g/m2 and a substrate basis weight of from about 20 to about 90 g/m2. Nonwoven substrates have the advantage of comprising a continuous synthetic filament such as a spunbond nonwoven, or a mechanically spun φ discontinuous carded staple fiber such as a needle or hydroentangled web. The type of pre-spun is generally not considered to be important. For thermally bonded spunbond webs, the spunbond area of the pqintb ned substrate is as low as about 7% and the degree of prespun adhesion to flat flat substrates is as high as 100%. The type will change. Preferably, the nonwoven substrate is spunbonded and typically has a spunbonded area of from about 1 Torr to about 20%. The second nonwoven substrate fiber can contain several commercially available materials. Advantageously, the substrate fibers include polyester, polyamide and polyolefins such as polyethylene and polypropylene, although other fibrous materials such as enamel, cotton, polylactic acid, -14-200837241 acetyl cellulose and acrylic can also be used. The first portion of the wet nonwoven web comprises a synthetic staple fiber, a natural pulp or a mixture of natural fibers and optionally other tanning materials and/or additives. The binder and other additives may be combined with the fluid and the fibers when the dispersion is formed to add different desired characteristics to the formed composite nonwoven fabric. For example, when the final product is used in the medical field, it may need to be mixed with the dip to provide biologically advantageous properties. Materials such as molecular sieves or similar compounds provide a location to attract or retain the biological composition of the wet non-woven layer, which helps maintain sterility in the environment in which the ® fabric is used. Of course, the amount of feed must be controlled to a level that does not adversely affect the desired softness, drape, and tactile properties of the final product. The first nonwoven fiber portion is wet. It typically involves the general step of forming the necessary fluid dispersion of fibers, pulp and other materials. The fluid dispersion is deposited on a porous member such as a fiber collecting metal mesh. Typically, the perforated component draws fluid from the dispersion to form a continuous sheet of mesh material. The wet web material forming ^ can be further dried using known methods such as heating cans, ovens or heated gases. Wet non-woven nets are preferred because of their inherent dimensional stability and anisotropy. The first wet non-woven fiber portion can be composed of a plurality of layers which are generally used to provide different functional properties to the name layer. The first wet non-woven fiber portion has the advantage of having a grams in the range of from about 20 to about 100 g/m2, wherein the final product has a grams in the range of from about 35 to about 250 g/m2 prior to the cognac treatment. Preferably, the range is from 3 5 to 1 60 g/m 2 . For the application of the garment, the wet-nonwoven fiber portion of the "Day-A" is preferably contained in a natural pulp of about 10 to 100% of softwood or hardwood or a combination thereof, and the remaining fiber is a composite fiber of 15-200837241. Other applications can foresee the need for 100% synthetic fiber to prevent the appearance of cellulose fibers from being contaminated. Preferred synthetic fibers are polyesters such as polyethylene terephthalate (PET), from about 1 to about 6 denier, preferably about 1.5 denier; fiber lengths ranging from about 0.25 to about 0.75 Torr (about 6 to about 20 mm), preferably about 0 · 25 ( (about 6 mm). Other suitable synthetic fibers include, but are not limited to, polyolefins such as polyethylene and polypropylene, polyamine and hydrazine. The natural pulp can be selected substantially from any of the pulps and blends thereof. The preferred ® pulps are all natural cellulose fibers and may contain wood fibers such as cotton. Although softwood pulps such as spruce, hemlock, cedar, and pine are preferred, they are generally used in combination with hardwood pulp such as eucalyptus. Non-wood pulp such as kenaf, kenaf, manila hemp and others can also be used. The natural pulp may be up to about 75 % by weight of the final product, including fibers, a bottom web and a binder composition. The amount of natural pulp can be substantially based on the needs of other compositions and end products in the composite system, such as the barrier capabilities that need to be exhibited when the resulting composite nonwoven is used in medical bandage applications. The first nonwoven fiber portion is applied directly to the second nonwoven substrate. In one embodiment, the material of the first wet nonwoven fibrous portion is dispersed in the fluid and the dispersion is applied to the second nonwoven substrate. A fluid is extracted from the first nonwoven fiber portion to provide a wet composite. In another embodiment, the first nonwoven web portion is deposited on a perforated member such as a fiber collection web. The fluid is extracted from the dispersion, typically via a perforated member, to form a continuous sheet of web material. The formed wet web material can be further dried by known methods such as a heating tank, an oven or a heated gas to provide a preformed first non-woven fabric. A preformed first wet nonwoven web portion is applied to the nonwoven substrate to provide a composite. After the application of the first fiber portion to the second substrate, the composite material is subjected to a low to medium pressure hydraulic entanglement operation as described in U.S. Patent No. 5,009,747, issued to the name of U.S. Pat. Reference materials. By a series of fluid jets through the composite material, the force is applied to the bottom of the substrate and entangled into a hydraulically entangled operation. Use a ^ string or - ^ row

A perforated jet is preferred, and the spacing between the holes is substantially defined by the aforementioned patent. The hydraulic enthalpy is a preferred method of combining the first portion with the second substrate, and the hydroentangled entanglement provides the final non-woven composite with parallel line micropatterns in the machine direction. The micro-twisted hydroentangled complex, the hydraulic entanglement parallel line combined with the microscopic pattern in the transverse mechanical direction produces the desired line of small squares. The hydroentangled nonwoven composite is dried in a conventional manner. The dried composite is treated with a liquid binder to provide stability for end use, including tensile strength, wash resistance, or other desirable characteristics depending on its end use. The addition of the binder can be accomplished by known methods such as a size-press, a curtain coater, a spray coater, and a foam coater. Suitable binders include chemical binders, commonly known as liquid dispersion binders such as acrylic, vinyl acetate, polyester, polyvinyl alcohol, and other conventional binders. For example, in medical applications, a small amount of soft acrylic adhesive can be used to control burrs or as a carrier for special colorants or dyes, or as a carrier for humectants to further enhance the absorbency of nonwoven composites -17-200837241. These soft adhesives are classified as having a low glass transition temperature ranging from about -5 to about 35 °C. For apparel applications, the preferred adhesive is still acrylic, although its glass transition temperature ranges from about 〇 to about 3 且 and is specifically designed for use in belts where fiber washing, drying and dry cleaning are critical. The binder content is from about 3 to about 35 wt% of the overall final nonwoven composite, with a median range of from 15 to 25% being advantageous for apparel applications, with about 20% being preferred. The binder content is from about 3 to about 35 wt% overall for the final nonwoven composite, and a range of from about 3 to about 1 〇% is advantageous for medical applications. After forming the wet nonwoven sheet, it is treated with an adhesive as needed and dried and then transferred to a micro-twisting process. The inventors believe that the illustrated micro-twisting process follows the general principles of microfiber processing, particularly in the combination of retarding and compressing wet non-woven boards when passing in and out of the drum, on wet non-woven webs. A series of small, substantially parallel folds are formed. The peaks and valleys of the fold will generally extend in the transverse mechanical direction, such as substantially transverse to the machine direction. The nonwoven web has a densification range of from 10 to 50%, preferably from about 15 to about 45%. The number of grams of the dense mesh is preferably in the range of 40 to 290 g/m2, more preferably in the range of 40 to 1 85 g/m2. The micro-treatment process provided by Micrex Corporation of Volbo, MA, USA is appropriate in accordance with the instruction number C2715. Micro-twisting machines are discussed in more detail, for example, in U.S. Patent No. 3,260,778, although a similar dry-creping can be utilized, for example, in U.S. Patents 3,23 6,7 1 8 , 3,8 1 0,280, 3,869. 7 68, 3,975,806, 4,142,278, 4,85 9,169 and 4,894,196 -18- 200837241 are mechanically agreed. Other alternative methods and devices suitable for performing cognac processing are discussed in U.S. Patents 2,9 15,109 and 4,090,3,85. The micro-twisting process is understood to include a driven roll and a pressing surface for pressing one or more webs against the drive shaft sufficient to move it forward, and advancing relative to the web. The dry total processing performed by the blade-like drycreper of the retarder blade in the direction of the net plane, the blade tip is maintained adjacent to the drive shaft, and the dryer has at least one surface plus heat The plastic fiber is composed of the thermosetting temperature of the thermoplastic fiber. In a preferred cognac process, the thermoplastic fibers comprise PET (polyester) fibers and the surface of the dryer is heated to temperatures between 250 °F and 350 °F (139 °C and 194 °C). In other embodiments of the process conditions, the shaft temperature can be higher (eg, higher speeds can be achieved with moisture removed to allow the fibers to reach the thermoset temperature faster) or lower (eg, if frictional heat provides additional heat to the shaft) fiber). Heat the stamped surface and/or the drive shaft. The drive shaft of the dryer includes a continuous cylinder to configure the shaft and an internal heater if required. The internal heater contains a heat exchange line that supplies the heating fluid. The hot fluid can be hot water, steam, hot or combustible gas, or oil. In the example of heating the stamped surface, the 'heating mode' can be any of a number of well known methods such as electrical resistance, steam, hot water, hot gases or hot air. Radiant heating or flame preheating can also be used. At the same time, the method of cognac treatment and thermosetting can shorten the net by at least 1% and increase the overall thickness of the sheet member. At the same time, the cognac treatment and the thermosetting method can shorten the mesh in the range of about 1 〇 to 50% °. During the compaction treatment, the heating net is heated to a temperature range of about 1 2 1 ° C (about -19-200837241 25 0 °F) to about 218 ° C (about 425 ° F), preferably in the range of about 149 ° C (about 300 to 40 (TF), and more preferably in the range of about 182 to (3 60 to 3 80 ° F), To reduce the exposure of the product to continuous shrinkage or expansion, especially in apparel applications, the product needs to go through the right (withstand process) to remove the fiber scar 'usually (3 25 °F), 15 minutes.

DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a micro-twist composite nonwoven fabric having improved size and thermal recovery and allowing continuous adjustment in dynamic use. [Prior Art] Elastomeric materials are widely used in a variety of applications, including belt linings, medical wraps and bandages, and functional dressing materials. Elastic materials have advantages over non-elastic products, including their comfort for body structure and movement, such as belt applications and medical wraps. In addition, when elastic materials are used in medical wraps or bandages, they are applied to the injured or injured area to provide medical comfort. In medical wraps or bandage applications, in order to accelerate the efficacy, the elastic material also needs to be breathable so that oxygen can be transported to the injured area and the water vapor and other gases escape from the injured area, and the absorption of blood and wound secretions It can be removed from the injured area by direct contact with the bandage. Absorptive force is also required when the elastic material is filled with topical ointments and other treatments such as anesthetics and subsequent treatment dressings. For apparel applications such as belt linings or embroidered base fabrics, the advantage of elastomeric materials is that they can be converted into yarn-forming, have high tensile strength and can be re-washed and applied dry-cleaning procedures without damaging or losing their elastic properties. Another feature of this product is that it must not decrease or only decrease in length in the CD direction when it is stretched in the MD direction. This is especially important in apparel applications where some of the materials used in the prior art tend to reduce the length in the transverse direction when stretched, causing the waistband to be distorted. Usually when the material is extended in one direction, it tends to be thinner in the other two directions (described by the material's Poisson ratio). Elastic materials with some or all of these qualities can be used in these areas: garment lining, medical 200837241 wraps and bandages, or functional dressing. However, it is practical to provide elastic materials with some or all of these qualities. For example, due to the limited elastically retractable stretch of non-woven fabrics, the garment industry resorts to expensive belts such as woven fabrics that use 45 degree twill cuts, or the use of knits, or the use of webs containing continuous elastomeric fibers, or the use of elastomeric films. Or use a variety of microgrids, or apply a complex waistband design that allows for overlapping overlapping fiber sections. In medical wraps or bandage applications, attempts have also been made to impart resilience, breathability and strength to resilient elastomeric materials. In addition to being woven into the elastic material layer or fibers, the stretching of the nonwoven web can be recovered, and the other methods are non-woven fabric treatment or micro-twisting treatment. At the time of processing, the non-woven net was attached to a surface and removed from the surface using a doctor blade. Upon micro-twisting, as it moves over or removes from the roller, the retractable extension of the nonwoven web is achieved by retarding and compressing the web. However, various application markets continue to look for suitable recyclable extended non-woven materials that combine other desirable application characteristics and maintain cost-effectiveness with simple production processes. SUMMARY OF THE INVENTION [Bicomponent fiber or filaments are defined as '- extruding a polymer source from a separate extruder and simultaneously spinning to form a single bundle of fibers or filaments, thereby forming a composite fiber or Filament. Two different polymers are typically extruded, although bicomponent fibers or filaments may comprise compacts extruded from different extruders of the same polymeric material. The polymer extruded -6-200837241 is arranged substantially in a distinct zone across the cross-section of the bicomponent fibers or filaments and extends substantially continuously along the length of the bicomponent fibers or filaments. The structure of the bicomponent fibers or filaments may be symmetrical (e.g., sheath-core or side-by-side) or asymmetrical (e.g., sheath-type lithography; the whole is circular and the fibers are crescent moon patterns). The ratio of the two polymer sources can be, for example, but not absolute, 75/25, 50/5 0, 25/75. A bicomponent fiber (b i c ο n s t i t u e n t f i b e r ): a fiber formed by mixing two or more polymers extruded from the same spinning nozzle. The bicomponent fibers do not have a plurality of polymer compositions arranged in a distinct region that is relatively transverse to the cross-sectional area of the fibers, and the plurality of polymers are generally not continuous along the total length of the fibers, and fibril formation typically begins and ends randomly. Double-component fibers are sometimes referred to as multi-component fibers. Calendering: A process in which the surface of a non-woven material is pressed between opposing surfaces. The opposite surface contains a flat platen and a roller. Any or both of the opposing surfaces can be heated. Any one or both of the opposing surfaces may include protrusions. Cellulosic material: A material that substantially contains cellulose. Cellulose fibers are derived from artificial sources (e.g., regenerated cellulose fibers or lyocell fibers) or natural sources such as fibers or wood and non-woody plant pulp. Woody plants contain, for example, deciduous and knotted fruit trees. Non-woody plants, such as cotton, flax, African feathers, sultans, manila hemp, milkweed, straw, jute, hemp, and sugar cane. 13⁄4 conjugate fiber or filament 200837241 A polymer source is extruded from a different extruder and spun at the same time to form a single bundle of fibers or filaments, thereby forming fibers or filaments. The composite fiber uses two or more polymers from different extruders. Typically the extruded polymer is disposed substantially in a distinct region at the cross-section across the composite fibers or filaments and extends substantially continuously along the length of the composite fibers or filaments. The shape of the composite fiber or filament may be any shape as long as it is convenient for the manufacturer, such as a circular, trilobal, triangular, dog bone type, flat plate or hollow. Creping and microcreping: A process of compacting a non-woven net in a mechanical direction, adding a series of generally discontinuous small parallel folds to the web. The difference between the micro-twisting treatment and the enamel treatment is mainly in the size of the attached and folded layers. Cross machine direction: This direction is perpendicular to the machine direction. Denier: A unit used to define the fineness of filaments, based on the weight of the 9000-meter filament. 1 Danny's 9000 meters filament has a mass of 1 gram. Drape (D r a p e ): The ability of the suspension material to produce loose or loose folds. Elastic Material: A stretchable material, especially when the force is released, it will return to its original shape or size due to ductility. Fiber: A material characterized by an extremely high ratio of length to radius. As indicated herein, the fibers and filaments are interchangeable unless otherwise indicated. Filament: A fiber that is substantially continuous. As indicated in the text 200837241, the fibers and filaments are interchangeable unless otherwise specified. Hardwood pulps: Any fibrous material derived from deciduous wood that is reduced to its constituents by mechanical means such as a pulp honing machine or by chemical means such as high temperature and pressure using various cooking alcohols. Deciduous trees include such as alder, birch, eucalyptus, oak, poplar, sycamore fig, fragrant maple and walnut. Heat setting: A process in which heat and pressure are applied to a substrate to accomplish certain desired effects. On fibers made of synthetic fibers, heat is fixed to prevent shrinkage or to cause scars or creases that may remain after washing or dry cleaning. Hydroentanglement: Use fine, high-pressure water jets to stagger non-woven fibers. Hydraulic sputum is known as spunlacing, and by arranging the jet stream, various aesthetic effects can be obtained. The water column pressure used is usually directly related to the strength of the mesh, but the system design also plays an important role. Non-woven webs of different characteristics can be hydraulically entangled to create non-woven composites that are difficult to achieve different grades by other means. Lyocell: A man-made cellulosic material obtained by directly dissolving cellulose in an organic solvent without forming an intermediate product, followed by extruding a cellulose solution and an organic solvent into a coagulation bath. Machine direction (Machine direction): When a non-woven mesh material is formed, the direction of movement of the surface in the direction in which the fibers or filaments are deposited is formed. Mechanical Bonding: In mechanical bonding, the strength of the non-woven mesh is achieved by the interfiber friction generated by the fiber-optic entanglement - 9-200837241. There are two forms of mechanical bonding, and the hydraulic knot is known as the hydraulic entanglement and the needle cart L. Meltblown fiber: A fiber formed by extruding a plurality of fine, usually annular, capillary die extruded molten thermoplastic materials into a stream of high velocity gas (e.g., air) which is melted at a high velocity gas stream. The thermoplastic material filaments are tapered to reduce their radius. The high velocity gas stream is then loaded with meltblown fibers and deposited on a collecting surface to form a randomly dispersed meltblown web. Melt blown fibers are generally continuous. The melt blowing procedure includes a meltblowing procedure. Natural fiber pulps: Any fibrous material from non-woody plants that is reduced to its constituents by mechanical means such as a pulp honing machine or by chemical means such as high temperature and pressure using various cooking alcohols. Non-woody plants include, for example, cotton, flax, African feathers, kenaf, manila hemp, milkweed, straw, jute, hemp, and bagasse. Needle rolling (N e e d 1 e p u n c h i n g ): In needle rolling, specially designed needles are pushed and pulled on the nonwoven web to entangle the fibers. The web is usually finished by carding but may also contain spunlaid and less used wet-bonded webs (w e 11 a i d w e b s ). Needle rolling can be used for most fiber types. Non-thermoplastic polymer: Any polymer material that is not a thermoplastic polymer definition. Nonwoven fabrics, sheets and webs: materials that have interwoven fiber structures in their respective shapes, but which can be used to identify non-woven or knitted fibers in their form. Nonwoven materials can be formed by a number of processes such as melt blowing, spunbonding, carding and wet lamination processes. -10- 200837241 The basis weight of non-woven fabrics is usually expressed in grams per metric gram of s r , u Yunli, gsm). Polymer - The long bond of a repeating organic structural unit contains both thermoplastic and non-thermoplastic polymers. Typically included are homopolymers, copolymers such as blocks, grafts, random and alternating copolymers, terpolymers, and the like, as well as mixtures and modifications thereof. In addition, the "polymer" contains all possible geometries unless otherwise specifically limited. The geometry may contain, for example, the same row, the opposite row, and the random symmetry. Regenerated cellulose • Cellulose obtained by chemically treating natural cellulose to form soluble chemical derivatives or intermediates and then decomposing the derivatives to produce cellulose. The regenerated cellulose comprises crepe and the regenerated cellulose process comprises the viscose process of the acetaminophen, the cuprammonium process and the emeraldization. Softwood pulps: Any fibrous material from conifers that is reduced to its constituents by mechanical means such as a pulp honing machine or by chemical means such as high temperature and pressure using a variety of cooking alcohols. Conifers include, for example, cedar, fir, hemlock, pine and spruce. S p u n b ο n d f i 1 a m e n t: a filament formed by extruding a molten thermoplastic material from a plurality of fine, usually annular, capillary die-spinning nozzles. The radius of the extruded filaments can be rapidly reduced by, for example, eductive drawing and/or the well known spunbonding mechanism. The spunbond fibers can have a single strand range of from about 0.1 to 5 or greater and are substantially continuous from one end of the nonwoven web to the opposite end. -11- 200837241 Spunbond nonowoven web: (usually) extruding at least one molten thermoplastic material from a plurality of fine, usually annular, capillary nozzles in a single process as a plurality a net formed by filaments. The filaments are partially annealed and then stretched to reduce the denier of the fibers and increase the forward orientation of the molecules in the fibers. The filaments are generally continuous and non-tacky when they are deposited on the collecting surface as fibrous batt. The fibrous batt is then bonded by, for example, thermal bonding, chemical bonding, mechanical pin rolling, hydraulic entanglement or a combination thereof to produce non-woven fibers. Staple fiber: A fiber (0.6 to 20 cm) formed or cut into a fiber length of usually 1/4 to 8 Å. Substantially continuous: For a filament of a non-woven web, it means that most of the filaments or fibers formed by extrusion from the orifice are maintained continuously while being stretched and then attached to the collection device. Unbroken filaments. Some filaments may break during the tapering or stretching process, while substantially most of the filaments still maintain the length of the complete sheet. Synthetic fiber: A fiber comprising an artificial material such as glass, a polymer or a combination of polymers, metal, carbon, regenerated cellulose and tencel fiber. Tex: A unit used to indicate the fineness of filaments, expressed in grams per 1,000 meters of filament. 1Texas filaments refer to filaments of length 1 000 m with a weight of 1 gram. Thermoplastic polymer: A meltable polymer that softens when exposed to heat and typically returns to its non-softened state when cooled to room temperature. Thermoplastic materials include, for example, polyvinyl chloride, some -12-200837241 polyester, polyamide, polyfluorocarbon, polyolefin, some polyurethane, polystyrene, polyvinyl alcohol, ethylene, and at least one vinyl A copolymer of a body (eg, poly(ethylene vinyl acetate)) and an acrylic resin. Web Bonding • Non-woven mesh, except for spunbond, has some micro strength when it is not bonded and needs to be strengthened by adhesion. The three basic bonding methods are thermal bonding, chemical bonding, and mechanical bonding. The importance of mode selection affects at least the functional properties of the fiber in the network.

As used herein, "about" means that the quantity or state correction may exceed its disclosure as long as its disclosure advantage is understandable. The invention can be better understood by the following detailed description, drawings, and embodiments of the invention. [Embodiment] In one embodiment, the elastic composite nonwoven material comprises a first wet (w e t - f 〇 r m e d ) nonwoven fiber portion applied to the second nonwoven fiber substrate. The second nonwoven substrate is a pre-bonded web such as a carded knit web, a spunbond web or a carded hydraulic web (generally referred to as water weave). The nonwoven web basis weight may range from about 15 to about 150 g/m2' with a substrate basis weight of from about 20 to about 90 g/m2. Nonwoven substrates have the advantage of comprising a continuous synthetic filament such as a spunbond nonwoven, or a mechanically spunbonded discontinuous carded staple fiber such as a needle-rolled or hydroentangled web. The type of pre-spun is generally not considered to be important. For thermally bonded spunbond webs, the spunbond area of a point boned substrate is as low as about 7% and the degree of prespun adhesion to a flat boned substrate is as high as 100%. The style will change. Preferably, the nonwoven substrate is spunbonded and typically has a spunbonded area of from about 1 Torr to about 20%. The second nonwoven substrate fiber can contain several commercially available materials. Advantageously, the substrate fibers include polyester, polyamide and polyolefins such as polyethylene and polypropylene, although other fibrous materials such as enamel, cotton, polylactic acid, • 14-200837241 acetyl cellulose and acrylic can also be used. The first portion of the wet nonwoven web comprises a synthetic staple fiber, a natural pulp or a mixture of natural fibers and optionally other tanning materials and/or additives. The binder and other additives may be combined with the fluid and the fibers when the dispersion is formed to add different desired characteristics to the formed composite nonwoven fabric. For example, when the final product is used in the medical field, it may need to be mixed with the dip to provide biologically advantageous properties. Materials such as molecular sieves or similar compounds provide a location to attract or retain the biological composition of the wet non-woven layer that helps maintain the sterility of the environment in which the nonwoven is used. Of course, the amount of feed must be controlled to a level that does not adversely affect the desired softness, drape, and tactile properties of the final product. The first nonwoven fiber portion is wet. It typically involves the general step of forming the necessary fluid dispersion of fibers, pulp and other materials. The fluid dispersion is deposited on a porous member such as a fiber collecting metal mesh. Typically, the perforated component draws fluid from the dispersion to form a continuous sheet of mesh material. The wet web material formed can be further dried using known methods such as heating cans, ovens or heated gases. Wet non-woven nets are preferred because of their inherent dimensional stability and anisotropy. The first wet non-woven fiber portion can be composed of a plurality of layers which are generally used to provide different functional properties to the name layer. The first wet non-woven fiber portion has the advantage of having a grams in the range of from about 20 to about 100 g/m2, wherein the final product is in the range of 35 to about 250 g/m before the cognac treatment. It is preferably in the range of 3 5 -1 60 g/m 2 . For apparel applications, the first wet non-woven fibrous portion preferably contains from about 1% to about 100% natural pulp of softwood or hardwood or a combination thereof, and the remaining fibers are -15-200837241. The softness and quantity of the • need to be in the middle of the loose mesh box fiber. Other applications can foresee the need for 100% synthetic fibers to be attributed to the appearance of cellulose fibers. Preferred synthetic fiber polyesters such as polyethylene terephthalate (PET), preferably from about 1 to about 6 denier, are about 1.5 denier; fiber lengths ranging from about 0.25 to about 〇吋 (about 6 to About 20 mm), preferably about 0 · 25 ( (about 6 mm) Other suitable synthetic fibers include, but are not limited to, polyethylene and polypropylene, polyamine and hydrazine derived from polyolefin. The natural pulp can be selected substantially from any of the pulps and blends thereof. Preferably, the pulps are all natural cellulose fibers and may contain wood fibers such as cotton. Although wood pulp such as spruce, hemlock, cedar, and pine are preferred, generally hardwood pulp such as eucalyptus is used in combination. Non-wood pulp such as Qiongma kenaf, Manila hemp and others can also be used. The natural pulp may be at most about 75 % by weight of the final product, including fibers, a bottom web and a binder composition. The natural amount can be substantially based on other compositions and final products in the composite system, such as when the resulting composite nonwoven is used in medical bandage applications. The first nonwoven fiber portion is applied directly to the second nonwoven substrate. In an embodiment, the material of the first wet nonwoven fibrous portion is dispersed in a stream and the dispersion is applied to the second nonwoven substrate. The fluid is extracted from the first nonwoven fiber to provide a wet composite. In another embodiment, the nonwoven web portion is deposited on a perforated member such as a fiber collection web. The fluid is extracted from the liquid, typically via a perforated member, to form a continuous sheet of material. The formed wet web material can be further dried by known methods such as heating cans, or heated gas to provide a preformed first non-16-200837241 dimension portion. A preformed first wet nonwoven web portion is applied to the second nonwoven substrate to provide a composite. After applying the first fiber portion to the second substrate, the composite material is subjected to a low to medium pressure hydraulic entanglement operation as described in U.S. Patent No. 5,009,747, issued to the name of Break into the reference here. A series of fluid jets are passed through the composite material to directly impact the top surface of the first wet portion with sufficient force to cause the surface fibers to be advanced into the second substrate and entangled to complete the hydraulic entanglement operation. It is preferred to use a series or a row of apertured jets and the spacing between the apertures is substantially defined by the aforementioned patent. Hydraulic entanglement is a preferred method of combining the first portion with the second substrate, and the hydroentanglement is provided by the entanglement spray to provide the final non-woven composite with parallel line micropatterns in the machine direction. The micro-twisted hydroentangled complex, the parallel line of hydraulic enthalpy and the microscopic pattern in the transverse mechanical direction can produce the desired line of small squares. The hydroentangled nonwoven composite is dried in a conventional manner. The dried composite is treated with a liquid binder to provide stability for end use, including tensile strength, wash resistance, or other desirable characteristics depending on its end use. The addition of the binder can be accomplished by known methods such as a size-press, a curtain coater, a spray coater, and a foam coater. Suitable binders include chemical binders, commonly known as liquid dispersion binders such as acrylic, vinyl acetate, polyester, polyvinyl alcohol, and other conventional binders. For example, in medical applications, a small amount of soft acrylic adhesive can be used to control burrs or as a carrier for special colorants or dyes, or as a carrier for humectants to further enhance the absorbency of nonwoven composites -17-200837241. These soft adhesives are generally classified as having a low glass transition temperature ranging from about -5 to about -3 5 °C. For apparel applications, the preferred binder is still acrylic, although its glass transition temperature ranges from about 0 to about 30 ° C and is specifically designed for use in belts where fiber washing, drying and dry cleaning are critical. . The binder content is from about 3 to about 35 wt% of the overall final nonwoven composite, with a median range of from 15 to 25% being advantageous for apparel applications, with about 20% being preferred. The binder content is from about 3 to about 35 wt% of the total final nonwoven composite, with a range of from about 3 to about 10% being advantageous for medical applications. After forming the wet nonwoven sheet, it is treated with an adhesive as needed and dried and then transferred to a micro-twisting process. The inventors believe that the illustrated micro-twisting process follows the general principles of micro-twisting, particularly in the combination of retarding and compressing wet non-woven boards when passing in and out of the drum, on wet non-woven webs. A series of small, substantially parallel folds are formed. The peaks and valleys of the fold generally extend in the transverse mechanical direction, such as generally transverse to the machine direction. The nonwoven web has a densification range of from 10 to 50%, preferably from about 15 to about 45%. The number of grams of the dense mesh is preferably in the range of 40 to 290 g/m2, more preferably in the range of 40 to 185 g/m2. According to the manual number C27 1 5, the micro-treatment process provided by Micrex Corporation of Volbo, MA is suitable. Micro-twisting machines are discussed in more detail, for example, in U.S. Patent No. 3,260,778, although similar dry-creping can be utilized, for example, in U.S. Patents 3,236,7,8, 3,8,0,280, 3,869,7,68. The machines discussed in 3,975,806, 4,1 42,278, 4,859,169 and 4,894,1 96 •18· 200837241 ^ were reached. Other alternative methods and devices suitable for performing cognac processing are discussed in U.S. Patents 2,915,1,9 and 4,090,385. ^ The micro-twisting process is understood to include a driven roll and a pressing surface for pressing one or more webs against the drive shaft sufficient to move it forward, and relative to the net The dry total process performed by the blade-like drycreper of the retarder blade in the direction of the web, the zero blade tip is maintained adjacent to the drive shaft, and the dryer has at least one surface heating The thermoplastic fibers constitute a thermosetting temperature to the thermoplastic fibers. In a preferred cognac process, the thermoplastic fibers comprise PET (polyester) fibers and the surface of the dryer is heated to temperatures between 250 °F and 3 50 °F (139 ° C and 194 ° C). In other embodiments of the process conditions, the shaft temperature can be higher (eg, higher speeds can be achieved with moisture removed to allow the fibers to reach the thermoset temperature faster) or lower (eg, if frictional heat provides additional heat to the shaft) fiber). Heat the stamped surface and/or the drive shaft. The drive shaft of the dryer consists of a continuous cylinder to accommodate the shaft, and an internal heater can be attached if required. The inner heater contains a heat exchange line through which the heating fluid passes. The hot fluid can be hot water, steam, hot or combustible gas, or oil. In the example of heating the stamped surface, the heating mode can be any of a number of well known methods such as electrical resistance, steam, hot water, hot gases or hot air. Radiant heating or flame preheating can also be used. At the same time, the method of cognac treatment and thermosetting can shorten the net by at least 1% and increase the overall thickness of the sheet member. At the same time, the method of cognac treatment and thermosetting can shorten the mesh in the range of about 1〇 to 50%. Heating the web during compaction to a temperature in the range of about 1 2 PC (about 19-200837241 250 °F) to about 218 ° C (about 4251), preferably in the range of about 149 to about 204 ° C (about 300 to 400 °F), and more preferably in the range of about 182 to about 193 ° C (3 60 to 3 80 ° F) 'to reduce shrinkage or expansion when the product is exposed to continuous heating, especially in apparel applications Withstand process to remove fiber scars, typically 163 ° C (325 ° F), 15 minutes. The rising temperature at the time of micro-twisting also requires heat setting of the micro-pattern and the separation of the wet-type non-woven fabric of the enamel treatment and the combination of the discontinuous fibers to the maximum. After the micro-twisting step, the non-woven fabric was lowered to room temperature. When visually inspected, the 绉 pattern is sufficiently fine to not change the surface feel of the mesh after the micro 绉 treatment. However, the micro-twisting step improves the overall drape of the web and introduces a reversible mechanical stretch. The final micro-non-woven elastic material exhibits an improved recovery stretch characteristic, including soothing tension and low distortion. Especially when the non-woven fabric is stretched up to 15% in the longitudinal direction, the lateral length does not increase. The following examples are intended to be illustrative only, and are not to be construed as limiting.
