The Designation "stretchy" is used here so that it should designate each material, which after application of elongation force is elongatable, up to an extended extension length and which will regress at least 50% of its elongation after relief across from the stretching, elongating force. A hypothetical example would be one (1) inches of sample material which is at least 3.81 cm (1.50 inches) (50% elongation) is expandable, and which, after it has been extended to 3.18 cm (1.50 inches) and relieved is, to a length return no more than 3.175 cm (1.25) (50% regression) inches becomes.

As As used herein, the term "nonwoven web" or "nonwoven web" means a web having one Structure of individual fibers or a network with a structure of individual fibers or threads, which superimposed are, but not in a regular or identifiable Way, as in knitwear and films, which fibrillates that is the case. Nonwoven web or nonwoven fabrics have been formed from many processes, such. B. meltblown processes, spunbond processes or bonded nonwoven processes. The basis weight of the fleece net or nonwoven fabric becomes common in ounces of material per square yard (osy) or grams per square meter (gsm) and the usable fiber diameter are usually expressed in microns. (Note that to convert osy to gsm osy multiplied by 33.91 must become).

As used here refers to the term "spunbonding (spunbond) Fibers "on fibers with small diameters, which are made by extruding molten thermoplastic materials, such as. B. filaments from a variety from fine usually Circular capillaries of a spinneret are formed with a Diameter of the extruded filaments then quickly reduced is taught, for example, by U.S. Patent 3,802,817 of Appel et al., U.S. Patent 3,692,618 to Dorschner et al., U.S. Patent 3,802,817 by Matsuki et al., U.S. Patent 3,338,992 and U.S. Patent 3,341,394 by Kinney, U.S. 3,502,763 to Hartmann, U.S. Patent 3,502,538 to Levy and U.S. Patent 3,542,615 to Dobo et al. Spunbond fibers are quenched and are generally not sticky when they are on a collecting Surface deposited become. Spunbond fibers are usually continuous and have average diameters greater than 7 microns, more precisely, between about 10 and 35 microns.

As As used herein, the term "meltblown fibers" refers to fibers which are formed are made by extruding a molten thermoplastic material through a variety of fine, usually Circular Blaskopf capillaries as molten threads or filaments in converging High-velocity gas streams (for example air streams), which are the filaments of the molten thermoplastic material dilute, to reduce the diameter, which up to microfiber diameter can be. Subsequently The meltblown fibers are transported through the high velocity gas streams and deposited on a collecting surface to form a network of fortuitously form distributed meltblown fibers. Such a procedure is disclosed, for example, by U.S. Patent 3,849,241 to Butin. Meltblown fibers are microfibers which are continuous or can be discontinuous, generally less than 10 microns in average diameter are sticky and generally sticky when collecting on a surface be deposited.

As used herein, the term "bonded carded web" refers to Nets consisting of staple fibers which are passed through a combining and carding unit which breaks up and aligns the staple fibers in the machine direction to produce a primarily machine direction oriented fibrous nonwoven web. Such fibers are usually sold in bundles which are placed in a picker which separates the fiber from each other before the carding unit. Once the network is formed, it is linked by one or more of the various known knotting methods.

As As used herein, the term "microfibers" refers to fibers of small size Diameter with an average diameter of not more than 75 microns, for example, with an average diameter of about 0.5 microns to about 50 microns or more, preferably with an average diameter of about 2 microns to about 14 microns. Another common used term in terms of fiber diameter is the denier, which is defined as grams per 9000 m as fiber and calculated can be expressed as fiber diameter in microns, squared, multiplied by density in g / cc multiplied by 0.00707. A low denier denotes a finer fiber and a high denier designated one thicker or heavier fiber. For example, a diameter a polypropylene fiber reported as 15 microns in a denier be converted by squaring, multiplying the results by 0.89 g / cc and multiply by 0.00707. Consequently, a 15 microns in size Polypropylene fiber has a denier of 1.42. Outside the United States the fineness of the measurement is usually rather the "tex", which is grams / km is defined on fiber. Tex can be calculated as Denier / 9.

The material comprises a nonwoven fabric consisting of two-component fibers containing a polyester and a second polymer, such as. B. polye Thylen. When the mesh is pattern-linked or point-linked, and subjected to a heating process after it has been bonded, it contracts, resulting in a nonwoven fabric which undergoes elastic recovery in both the machine direction and the vertical direction shows when stretched up to about 30%. The unbonded web is preferably heated to a temperature of at least about 104.4 ° C (220 ° F). The degree of sticking as well as the recovery is adjustable by varying the "contraction" temperature and / or the interfacing area and / or the polyester content Moreover, the amount of shrinkage increases as the basis weight of the nonwoven web increases.

1 Figure 10 is a schematic diagram of a process flow for making a stretchable nonwoven web in accordance with this invention. The process flow 10 is arranged so that continuous Zweikomponentenfilamente be generated. The process flow 10 contains a pair of extruders 12a and 12b for separately extruding a polymer component A, a polyester in the present case, and a polymer component B, for example an olefin. Polymer A is in the corresponding extruders 12a filled in by a first knight 14a , and polymer component B is introduced into the corresponding extruder 12b from a second jumper 14b filled. Polymer components A and B are from the extruders 12a and 12b through the appropriate polymer lines 16a and 16b to a spinneret 18 directed. Spinnerets are well known to those skilled in the art and thus will not be described in detail here. In general, the spinneret contains 18 a housing having a spinning unit containing a plurality of plates stacked on top of each other, arranged with a pattern of openings so that web paths for separately directing polymer A and B through the spinneret are created. The spinneret 18 has openings arranged in one or more rows. The spinneret openings form a downwardly extending curtain of filaments as the polymers are extruded through the spinneret. For purposes of the invention, the spinneret 18 arranged so that two-component fibers are formed, wherein both polymer A and polymer B are deposited as a part of the surface thereof. Such bicomponent fibers include side-by-side arrangements, pie arrangements, and polylobal arrangements in which at least one of the polymers forms part of the lobes, the lobes being spaced apart and the second polymer being centrally distributed and at least part of the lumps Surface can be seen in the area between the lobules.

The process flow 10 also contains a quench fan 20 arranged adjacent to the shape of filaments extending from the spinneret 18 expand. Air from the quench air blower 20 quivers the filaments stretching from the spinneret 18 expand. A fiber-optic unit or aspirator 22 is below the spinneret 18 arranged and picks up the quenched filaments. Fibrous units or aspirators for use in melt-spun polymers are well known to those skilled in the art. Suitable fiber tow units for use in this process include a linear fiber aspirator of the type shown in U.S. Patent 3,802,817 and ductile guns of the type shown in U.S. Patents 3,692,618 and 3,423,266.

Generally described, the fiber draw unit includes an elongate, vertical passage through which the filaments are drawn, humidifying air as penetrated from the sides of the passage and flowing down through the passage. The heater 24 supplies the hot humidified air of the fiber-optic unit 22 , The hot humidified air draws the filaments and humidified air through the fiber-optic unit 22 ,

An infinite dotted training surface 26 is positioned below the fiber draw unit and takes the continuous filaments from the outlet opening of the fiber draw unit 22 on. The training surface 26 runs around guide rollers 28 , A vacuum 30 positioned below the forming surface 26 where the filaments are deposited attracts the filaments to the forming surface.

The process flow 10 further comprises a compression roller 32 , which, together with the furthest forward guide rollers 28 , the network as it is from the training surface 26 is deducted, absorbs. In addition, the process flow includes 10 further a linking device, such. For example, for pattern linking or thermal point-linking, 34 ,

Thermal point bonding involves passing a fiber or web of fibers to be bonded between a heated calender roll and an anvil roll. The calender roll is usually, but not always, patterned in any way so that the entire product is not bonded over the entire surface. As a result, various patterns for calender rolls have been developed for functional as well as aesthetic reasons. An example of a pattern has dots and is the Hansen-Pennings "H &P" pattern with about 30% mating area at about 200 joins / 6,54 cm ² (square inches) and is taught in U.S. Patent No. 3,855,046 to Hansen and Pennings. The H & P pattern has square or PIN pad areas, each PIN having a side dimension of 0.038 inches (0.965 mm), an extension of 0.070 inches (1.778 mm) between the PINs and a depth of the link of 0.023 inches (0.584 mm) , The resulting pattern has an associated area of approximately 29.5%. Another typical point merge pattern is the extended Hansen and Pennings or "EHP" (expanded Hansen and Pennings) join pattern, which creates a 15% join area with a square PIN with a side dimension of 0.037 inches (0.94 mm) PIN extent of 0.097 inches (2.444 mm) and a depth of 0.039 inches (0.001 mm) Another typical dot-tie pattern named "714" has square pin-tie surfaces, with each pin having a side dimension of 0.584 mm (0.023 inches) Inch), has an extension of 0.062 inches (1.575 mm) between the PINs and a depth of linkage of 0.033 inches (0.838 mm). The resulting pattern has a bonding area of about 15%. Yet another common pattern is the C-Star pattern, which has a mating area of approximately 16.9%. The C-Star pattern has a vertically oriented cross stripe or "corduroy" design punctuated by shooting stars.Other common patterns include diamond patterns with repeating and slightly unfilled diamonds, and an electromagnetic wave pattern that looks like this as the name suggests, for example, like a screen.

Below the thermal point-linking roller 34 is a hot air knife 36 or another heating process, such as As an oven to heat the network to a desired temperature. A conventional hot air knife includes a mandrel having a slot which blows a stream of hot air onto the nonwoven web surface. Such hot air knives are taught, for example, by U.S. Patent No. 4,567,796 to Kloehn et al. Alternatively, the material may be cleaned, washed and dried at elevated temperatures to achieve the desired contraction.
