Abstract
There is disclosed a process which comprises the steps of: (a) bonding a web of fusible staple fibers by thermal bonding in an intermittent pattern; (b) stretching the bonded web at elevated temperature; and (c) cooling the stretched web, to thereby produce a fabric having elastic properties perpendicular to the direction of stretch.
Description
a 5 9 8 3 - 2 - The invention relates to a process for producing an elastic thermal bonded non-woven fabric, and to the fabric that is produced by said process* Non-woven fabrics having elastic properties in one direction have enhanced utility for applications such as facing layers for sanitary napkins, diapers, and the like, wherein the elasticity of the fabric provides a "give" in the fabric so that the facing sheet will more readily conform to changes in the shape of the object in response to bodily movenent. This invention provides a lightweight, non-woven fabric having elasticity in one direction, and hence the fabric of the invention has enhanced utility for such applications.
The invention provides a process which comprises: (a) bonding a web of fusible staple fibers by thermal embossing in an intermittent pattern; and (b) stretching the bonded web at elevated temperature, to thereby produce a fabric having elastic properties in the direction perpendicular to the direction of the stretch.
Ness, in U.S. Patent No. 3,405,695, discloses a multi-step process for producing a nonaoven fabric having unidirectional elasticity. The steps in the Ness patent are the following: 1. Forming a fibrous web; 2. Rearranging the fibers in the web to form a fibrous web having staggered pores; 3. Bonding the web; 4. Drying the bonded web; 5. Drafting the dried, bonded web to elongate said pores;. 6. Applying the elastomeric binder to the drafted web; and 7. Drying and setting the elastomeric binder.
Ostermeier, in U.S. Patent No. 3,949,120, discloses a nonwoven fabric having bi-directional elasticity. The fabric is composed of spot-bonded continuous and randomly deposited filaments.
In the accompanying drawings: Fig. 1 is a side elevation, partially schematic, of one arrangement of apparatus suitable for carrying out the process of the invention; Fig. 2 is a top plan view, partially schematic, of another arrangement of apparatus suitable for carrying out the process of the invention; - 4 - Fig. 3 shows the embossed pattern of the surface of an cnbossed calender roll suitable for use in the process of the invention; Fig. 4 is a cross-section taken along lines 4-4 of Fig. 3; 5 Fig. 5 shows the pattern of the surface of another embos sed calender roll suitable for use in the invention; and Fig. 6 is a cross-section taken along line 6-6 of Fig. 5.
Referring first to Fig. 1, one preferred arrangement of apparatus for carrying out the process of the invention is 10 shown. A web 10 of staple length fusible fibers is fed, as by an endless belt 14, to a calender 12 composed of two rolls 16, 10. The upper roll 16 has an embossed intermittent pattern (which will be described in more detail below), and the lower roll 10 is a smooth back-up roll. 15 Both rolls are heated to a temperature such that the fusible fibers comprising the web 10 are heated to their thermal bonding temperature. Thus, as the web 10 passes through the calender 12, it is thermally bonded in an intermittent pattern corresponding to the embossed pattern 20 of the upper roll 16. The thermally bonded web 20 then proceeds past a set of rolls 22, 23 that are driven at the same circumferential speed as the calender rolls 16, 18, through an oven 24, and finally to a windup 26. The windup 26 is being driven at a speed such that its 25 circumference is moving faster than the speed of the cir cumferences of the two rolls 16, 18 comprising the calender 12. Therefore, the thermal bonded fabric 20 is stretched in the machine direction as it passes through the oven. Upon cooling, the thus produced fabric 20 will 30 have clastic properties in the cross direction, i.e., the direction transverse to that of the stretch. - 5 - Referring now to Fig. 2, an alternate arrangement of apparatus for carrying out the process of the invention is shown. As with the apparatus discussed in connection with Fig. 1, a web 10 of staple length fusible fibers is fed to 5 a calender 12, composed of an embossed roll 16 and a snooth backup roll (not shown)D The calender is heated to a temperature such that the fusible fibers comprising the web 10 are heated to their thermal bonding temperature, so that the fabric is thermal bonded in a pattern correspond-10 ing to the pattern of the embossed roll 16, which is an intermittent pattern. The thermal bonded web 20 has a width, Wl, after having been thermal bonded. The thermal bonded web 20 is then fed to a heated tenter frame 30, wherein the bonded web 20 is heated and stretched in the 15 cross direction as it passes through the tenter frame 30. After passing through the tenter frame 30, the width, W2, of the fabric 32 will be slightly greater than the width, vil of the fabric 20 as it was fed into the tenter frame 30. The fabric 32, after it cools, will then have elastic 20 properties in the machine direction (i.e„, in the direction of the arrow "a"), which is the direction transverse to that to which the fabric was stretched while being heated.
The processes described above are preferred embodiments of 25 the invention wherein the fabric is thermally bonded and then stretched (while being heated) to impart elasticity, in one continuous operation. However, if desired, the fabric may be thermal bonded, collected, and in a subsequent operation, nay then be stretched (while being 30 heated) to impart elasticity to the web.
The fibers that are employed in the invention are heat-fusible fibers such as polypropylene fibers, high density polyethylene fibers, polyester fibers, or conjugate fibers having an outer layer of a heat fusible material such as sheath/core polyethylene/polypropylene fibers having a sheath of polyethylene and a core of polypropylene, and sheath/core polyethylene/polyester fibers having a sheath of polyethylene and a core of polyester. Such heat fusible fibers are connercially available. The fibers that are employed are of staple length, that is, they are usually in excess of about one-half inch in length, up to about three or four inches long. They usually have a denier within the range from about one to about six.
Fibers that are not normally heat-fusible can be used in admixture with the heat-fusible fibers,in minor amounts. Such other fibers include rayon, cotton, wood pulp, and the like.
The feed web 10 employed in the invention is preferably a random web of staple fibers. Random webs are nade by known procedures, such as by employing a RAIJDO WEBBER, or a dual rotor, such as is described by Ruffo and Goyal in U.S. Patent no. 3,760,110. The feed web can weigh, for instance, from about 0.3 to about six ounces per square yard. The exact weight of the feed web has not been found to be narrowly critical.
Uhile the use of random webs is preferred, oriented webs such as card webs can also be used in the invention. When oriented webs are used, in most cases the direction of stretch will be in the direction of fiber orientation (i.e., usually in the machine direction), because the oriented web is usually not strong enough in the direction perpendicular to the orientation to support tension in that (perpendicular) direction.
The thermal bonding of the fibers in the feed web is carried out on an embossed bonder, such as is illustrated in the drawings. The bonder has one roll that has a - 7 - raised intermittent pattern on its surface, with the other roll being a smooth back-up roll. The temperature at which the thermal bonding is carried out, of course, is dependent upon the nature of the fusible material in the 5 feed web, as well as the weight of the web and the speed of the web through the bonder. For instance, at very high speeds, it may be desirable to use a pre-heater in order to heat up the web to close to the bonding temperature just prior to its entrance into the bonder. The bonding 10 temperature of the web is particularly determined by the nature of the material that is thermally bondable. For instance, if the fusible material is high density polyethylene, as it will be in a conjugate fiber having a sheath of high density polyethylene, the bonding tenpera-15 ture is usually within the range of from about 100° to about 150"Co If the fusible material in the web is polypropylene, the bonding tenperature is usually from about 130°C. to about 190"C. However, the exact bonding temperature is not narrowly critical. The important thing is 20 that the temperature be sufficiently high to soften the fiber so that the pressure from the bonder will cause adhesion of the fusible fibers to one another in a pattern corresponding to the pattern of the embossed roll.
Figs. 3 and 4 illustrate a typical intermittent embossed 25 pattern (a diamond pattern) that is suitable for U6e in the invention. The exact dimensions of one embodiment of the pattern are given below in the examples. In & preferred way of carrying out the invention, one axis of the diamond pattern is slightly longer than the other 30 axis. In such a case, when the fabric is stretched, it is preferably stretched in the direction of the longer of the two axes.
Other intermittent patterns can also bo used in the invention, as is illustrated by the embossed pattern shown in Figs. 5 and 6. The only requirement is that there be alternating areas of bonded and unbonded fibers. Thus, overall bonded thermal bonded fabrics cannot be used in the invention.
The pressure on the calender bonder has not been found to be narrowly critical. It will normally be within the range of from about 13 to about 350 pounds per linear inch.
After having been thernal bonded, the bonded fabric is then subjected to a stretch while being heated, h stretching of from about 5% up to perhaps 40§ or 50% is feasible, although a stretching of from about 15§ to about 30% is preferred. As was discussed above, the stretching can either be in the machine direction, which is more readily carried out because the equipment therefor is less expensive, or it can be in the cross direction if one employs a heated tenter frame to do the stretching. \Jhile the fabric is being stretched, it is also subjected to elevated temperature, of from, for example, about 100° to about 160°C.
The exact temperature to which the fabric is heated while being stretched depends upon the nature of the fusible fiber in the fabric, since the temperature should be about the softening point of the fiber.
The examples below illustrate the practice of the invention.
F.xample 1 A random laid web of staple fibers was employed in this exanple. The web was composed of 75 weight per cent of - 9 - 3 denier polypropylene fibers having a staple length of one and one-half inches, and 25 weight per cent of 1.5 denier polyester fibers having a staple length of one and one-half inches. The total base web weight was 60 grans 5 per square meter, or 1,77 ounces per square yard. This web was subjected to thermal emboss bonding using an emboss bonder having a raised emboss pattern as shown in Figs. 3 and 4. The raised emboss lines 40 were in a diamond pattern, with the dimensions BA" being 5.5 10 millimeters, the dimensions "B" being 0.8 millineter, and the dimension "C" being 0.035 millimeter. The angles "D" were 30°.
In Example 1, the long axis of the diamond was oriented in the cross direction. The above-described web was fed 15 through the emboss bonder, which was heated to a temperature of 165°C. The pressure on the web as it passed through the emboss bonder was 270 pounds per linear inch.
After having been thermally emboss bonded, the web was passed through a heated tenter frame where it was 20 stretched to a final width, W2, that was 125% of the unstretched width, W1 (See Fig. 2). The tenter frame was maintained at a temperature of 140°C.
The properties of the resulting fabric, both before stretching and after stretching, are displayed below in 25 Table Is - 10 - Table I Weight, oz./yard2 Before After Stretching Stretching Variation 1.77 2.21 +25S Tensile strength, CD, pounds per inch, 12 ply 39.5 62.1 +575 Tensile strength, MD, pounds 10 per inch, 12 ply 15.5 11.65 -25® CD elongation before breaking, per cent 19.2 9.6 -50% MD elongation before breaking, per cent 16.8 74.4 340% 15 Example 2 20 In this example, a web similar to that employed in Example 1 was used, except that it had a basis weight of 25 grams per square meter (0.74 ounces per square yard). In this example, the emboss pattern was the same as that used in Example 1, except that the long axis of the diamond pattern was oriented in the machine direction. 25 The web was fed through the enboss bonder at a speed of 10 yards per minute, with the emboss bonder being maintained at a temperature of 160°C. The pressure on the web going through the bonder was 360 pounds per linear inch. In this example, the windup batcher was run at a speed of 12.5 yards per minute, which is 125 per cent of the speed - 11 - of the web that t»as fed into the emboss bonder. In between the emboss bonder and the batcher, there was an oven, in which the web was heated to a tenperature of 140'C. 5 The properties of the fabric so produced are shown in Table II: Table II Before After Stretching Stretching Variation 10 Weight (oz. per square yard) 0.67 1.06 +44% Tensile strength CD, 12.94 6.73 -405 pounds/inch, 12 ply 15 Tensile strength MD pounds/inch, 12 ply 27.19 41.4 +52% CD elongation before breaking, per cent 37.2 91.2 + 145$ MD elongation before breaking, per cent 14.4 7.2 -505 20 In Examples 1 and 2, the increased elasticity in the direction transverse to that to which the web was stretched is shown by the markedly increased elongation in that direction. The fabrics produced by this invention have enhanced utility as facing fabrics for articles such 25 as sanitary napkins, disposable diapers, bandages, and the like, in which a degree of stretch in one direction is useful in order to help permit the article having the - 12 - fabric as a facing fabric to conform more readily to bodily movement.
Example 3 The procedure of Example 2 was repeated, except that the 75% polypropylene/25% polyester fibrous feed web was a carded web weighing 0.67 ounces per square yard.
The web was fed through the emboss bonder at a speed of 10 yards per minute, with the emboss bonder being maintained at a temperature of 150®Co The pressure on the web going through the bonder was 200 pounds per linear inch. In this example, the windup batcher was run at a speed of 13 yards per minute, which is 130 per cent of the speed of the web that was fed into the emboss bonder. In between the emboss bonder and the batcher, there was an oven, in which the web was heated to a temperature of 120°C.
