It is easier to be provided with breathability or microporosity. This thin film may have an effective size or thickness of 0.6 mils or less, and a basis weight of 25.0 grams (25 gsm) or less per square meter. In particular, when this low-thickness film is achieved by stretching or stretching (as in its mechanical orientation), then this stretching or stretching effect will cause the polymer molecules located in the film to face the direction of extension, Therefore, the toughness of the film in the mechanical orientation is increased. However, the tensile strength and tear-catching properties of the film oriented in the same mechanical direction will become weaker. In order to compensate for the fragility of the structure of the single-direction stretch film, a support layer (or most support layers), such as a fibrous non-woven fabric, has been laminated to form the film layer in order to form a layer with other characteristics such as lifting Laminated products such as toughness and durability. Stretched thin films and non-woven laminates have been formed using thermal lamination techniques, where heat and pressure, such as heating model rolls and ultrasound, have been applied. However, in the lamination of film and non-woven fabric, the polymer material using this film and non-woven fabric needs to be thermally compatible, that is, the polymer can be thermally bonded to transfer a 20 g Or greater peel strength. Therefore, thermal lamination techniques limit the freedom to choose films and / or nonwoven polymers in terms of cost alone, processing and / or performance criteria, and so on. In addition, even heat-stable valley polymers may require a certain degree of heat and pressure, which may cause unwanted perforations to appear on the film, causing damage to the film layer, and / or This results in an undesirable stiffness of the laminate. Finally, this heat-laminated film-non-woven laminate is used in some cases, especially when it is applied as an outer cover for a person's care with an absorbent article (read the precautions on the back and then the page) • Package.

This melt-spun filament is formed by a spunbond process, which is usually continuous and based on at least 5 measurements. It is known that it has an average diameter greater than 7 microns, and more particularly between about 10 to 1 〇stroms. Another commonly used representation of the diameter of a fiber or filament is denier, which is defined as the number of grams of fiber or filament per 9,000 meters. This spunbond process can also be used to form bi-component spunbond non-woven fabrics, such as spunbond double-row growth fibers made of side-by-side or sheath-core linear low density polyethylene / polypropylene.

Description of the invention (10) When one or both sides of this long-fiber curtain is in contact with a quench air, it should at least quench the filament And develops into a latent crimp in the filaments extending from the spinneret. Typically, this quenched air will typically be at a speed from about 30 to about 120 meters per minute, and a temperature of about 7 degrees Celsius (.C) to about 32 degrees Celsius. In the state of C, it is guided perpendicularly to the longitudinal direction of the filament. A fiber drawing unit or suction device is placed under the spinneret to receive the quenched filament. Fiber drawing units or spinnerets for use in melt-spun polymers are well known in the art. Typical fiber drawing units suitable for this process include a linear fiber suction device type shown in U.S. Patent No. 3,8 0 2,81 7 filed by Matsuki et al., And

The fiber drawing unit generally has an elongated channel passing through the filaments drawn by the suction airflow through the channel. This suction gas can be any gas, such as air, which will not adversely interact with this filament polymer. A conventional structured heater applies hot suction gas to the fiber drawing unit. When the sucking gas pulls the quenched filament and the surrounding air through the fiber pulling unit, the filament is heated to a temperature that activates the latent curl inside it. The temperature ' required to activate the crimping within the filaments ' typically ranges from about 43 ° C to a maximum temperature that is less than the melting point of the low-melting constituent fibers. In general, a higher air temperature will produce more curls per filament length.

Invention Description (U) ^ ~~ Pulling, followed by forming a substantially straight or non-curly spunbond filament fabric. The drawn and crimped filament exits the fiber drawing unit and is deposited on a continuous forming surface in an arbitrary form and usually by means of a hollowing device placed below the forming surface. The purpose of this hollowing is to eliminate the undesired scattering of the long fibers, and to guide the long fibers to the forming surface to form a homogeneous, non-adhesive two-component long fiber nonwoven fabric. If desired, the bicomponent spunbond fabric produced by this result can be treated as described in the pre-bonding, or secondary bonding, described below. Spunbond fabrics are usually stabilized or solidified in some form when they are produced, in order to provide the fabric with sufficient integrity and toughness, so that it can withstand further harsh manufacturing processes, and The final product is formed. This pre-bonding step can be accomplished by applying a heat-activatable adhesive in liquid or powder form to the filament, or more generally using a compact roller. As used herein, the term Π compact roller π means a set of rollers above and below this non-woven fabric, which is processed by processing a newly produced, melt-spun filament, especially spunbond fabric, and It is used to compact the fabric so as to provide the fabric with sufficient integrity to withstand further processing, but it is not as good as later applied, that is, a second closing process, such as through-air bonding, heat bonding Legal, ultrasonic bonding, and similar methods. The compact roller compacts the fabric slightly to increase the adhesion of the fabric itself and the resulting integrity.

The film layer used in the present invention described in the following example is a single-layer film. However, other types, such as multilayer films, are within the scope of the present invention, and their forming technology is compatible with filling films. Can be considered. The first formed film is usually thicker and noisier than expected, and when it shakes, it tends to make a "quack" sound. What's more, when measuring the water vapor transmission rate of this film, it was found that it does not have a sufficient degree of air permeability. Therefore, this film is heated to an amount equal to, or lower than about 5. C. The melting point temperature of this polyolefin polymer, and then using a linear mechanical direction positioning (MDO) unit 'extended to at least about twice (2χ) its original original length' to thin the film and provide its porosity Sex. Further extending the film layer (彳 2) to about twice (3X) its length, four times (4 X), or more than its original length will be particularly important for forming the film layer (12) of the present invention. Longing for things. The film layer (12), after being stretched and thinned, should have an " effective " film thickness, from about 0.2 mils to about 0.6 mils. This effective thickness is for those present in the breathable film layer Voids or gas spaces will be considered. Normally, for non-filled, non-breathable films, the actual thickness and effective thickness of this film will typically be the same.

Description of the invention (18) As for the stretch-thin filled film described here, this film The thickness also includes air gaps. In order to ignore this additional volume, the effective thickness will be estimated according to the test method stated here. Another additional feature of the stretch-thinning process is that the opacity of the film material is changed. When formed, the film was relatively transparent, but in the After extending the film becomes opaque. Further, when this film becomes thinner with directional stretching process, it also becomes softer and "the degree of Ga # ·· acoustic noise will be reduced. This uniaxial, mechanically oriented film, typically in a cross-mechanical position, does not have good toughness characteristics, which will cause the film to be easily torn or separated along the mechanical orientation (ie, the direction of extension). An attempted method to solve this "tearing" problem that exists in this stretched and thin film is to use thermal dead junction to bond this film layer to a fibrous nonwoven or nonwoven layer, most of which The reinforcing effect of the fibrous support layer, which will be described later, determines the characteristics such as durability and toughness of the film-nonwoven laminate produced as a result. However, as noted herein, this heat-bonded film nonwoven laminate exhibits certain specific shortcomings, particularly in combination with a filler film positioned in a mechanical orientation that is stretched up to four times its original length to enhance the film. When it is microporous or breathable. The adhesive-reinforcing film-nonwoven of the present invention, when compared with a heat-sealable film-nonwoven laminate, will allow thermally incompatible films and non-wovens, such as LLDPE films and polypropylene non-wovens. , Can be effectively laminated to each other. The resulting laminate has excellent aesthetic characteristics, such as hand and touch, the toughness, durability and toughness of the laminate P! S: p〇l-0404 \ pk-0〇l.〇4n4 .1

The example description of the disclosure is incorporated herein by reference. Other processes suitable for applying a desiccant to this film layer (12) include, for example, a 'sprayed or vortexed hot melt adhesive area, and screen or gravure printing of the desiccant area. This melt spraying and adhesive printing process is well known in this technical field and will not be described in detail here. The application of adhesives, especially colored adhesives, utilizes this printing process to provide additional aesthetic value. For example, the adhesive model pattern can use a geometric or non-geometric form, as well as repeated or non- Repeated appearance, continuous or discontinuous lines, novel or deliberate designs, symbols or objects, or even documents or fonts. The adhesive model patterns shown in Figures 3 and 4 illustrate this type of printed adhesive pattern. Certain printing processes, such as screen printing, need to guide the contact between this screen and the substrate being printed. Special types of adhesives, such as some pressure-sensitive adhesives, can be printed to check for problems caused by the high viscosity or adhesion of the adhesive at room temperature. However, the screen printing of such adhesives can be achieved by printing the adhesive on a suitable release surface, such as a release paper, and then adhering the film layer (1 2). Before bonding to the non-woven layer (16) <, the printed adhesive is transferred from this loosened surface to the film layer (12).

When it is applied to one surface of the non-woven layer (16), based on the non-woven fiber nature, the homogeneity of the adhesive obtained to reinforce the film layer (12) will be reduced. The adhesive can penetrate into and pass through the spaces between the individual fibers of this non-woven layer (16), thereby reducing the continuity of the adhesive and thus strengthening the film layer (彳 2). Especially for the printing adhesive of the screen or the pattern, the application of the adhesive to the non-woven layer results in an unclear definition of the pattern of the pattern, which reduces the original aesthetics of the adhesive printing process here.
