Definitions

  • Extensible (compacted) paper produced, for example, in accordance with the apparatus and process disclosed in US. Pat. No. 2,624,245 has certain well recognized advantages and commercial uses. Such paper is subjected, while in a partially moistened condition, to compressive compaction in the direction of web movement (machine direction or MD) between a pres sure nip, thus compacting and forcing the fibers together to produce an inherent stretchability without creping.
  • Compacted paper has improved tensile energy absorption (TEA) burst and tear characteristics which are highly desirable for such end uses as the manufacture of paper sacks.
  • extensible paper has reduced tensile strength and stiffness, the diminution of the latter characteristic increasing the difiiculty of converting this paper into sacks.
  • a method for externally sizing compacted paper web has been devised wherein starch in solution, eg. potato, corn or wheat starch is impregnated under pressure into both sides of the web by percentage weight of l to 10% while moisture absorbed by the web is controlled such that after drying the web retains essentially all of the improved qualities afforded by compaction and is further improved in its tensile, burst, TEA and stiffness qualities.
  • the stiffness imparted by such treatment produces compacted paper approximately as stiff as noncompacted paper (rendering such paper easily convertible into sacks) while the other enumerated strength qualities are drastically improved in comparison to compacted paper and of course non-compacted paper.
  • internal resin sizing may be used to control the degree of moisture absorption during the application of the starch solution to the web.
  • Other techniques for selectively controlling moisture absorption may also be used, for example, the strength of the starch solution may be regulated in accordance with the elapsed time from the application of the starch solution to the web to the subsequent drying of the web.
  • relatively unrefined or unbeated paper fibers may be treated in accordance with the inventive method to produce a paper product having optimum or near optimum tensile and tear strengths.
  • Unrefined paper fibers in a web exhibit relatively greater tear strengths and lesser tensile strengths than does a web produced from refined fibers.
  • the impregnation of starch sizing as disclosed herein can produce a commensurate increase in tensile strength with respect to unrefined fiber webs, without substantial loss in tear strength.
  • FIG. 1 is a schematic representation of a compactor for producing extensible paper
  • FIG. 2 is a schematic representation of dryer sections which receive the compacted web after processing by the apparatus of FIG. 1 and a size press intermediate said dryer sections for applying a solution of starch into the web;
  • FIG. 3 is a schematic illustration of an alternate form of the invention wherein the compacted web is fed directly to a size press and therefrom to a dryer section, and
  • FIGS. 49 illustrate graphically the effects of varying percentages of starch vis a vis different strength factors, compacted and uncompacted paper.
  • FIG. 1 illustrates generally a compactor 10 for producing an uncreped extensible paper web 11.
  • the apparatus 10 includes a loopedelastomeric traveling belt 12, and a rotary cylin 'der 13 having a smooth (chrome plated) outer surface for receiving the web 11 thereon.
  • a plurality of guide rolls l4, l5, l6 and 17 are positioned within the loop of the belt 12, guide roll 14 operating to squeeze the belt 12 against the cylinder 13 at a press nip N wherein the belt 12 is temporarily reduced in thickness as it travels therethrough.
  • a section of the guide rolls 15 is spaced from the first guide roll 14 and urges a portion 12a of the belt against the cylinder 13 at the offrunning side of the nip N, and web guide means 18, 19 feed the web onto the cylinder 13 for movement through the nip N.
  • the apparatus 10 is shown located in a paper machine between the second and third dryer sections.
  • a dryer roll shown fragmentarily at 20 indicates the last roll of the second dryer section and the roll 33 (also shown fragmentarily) indicates the first roll of the third dryer section 30.
  • the web is conveyed from the dryer roll 20 beneath the paper roll 19 and over an expander (paper guide) roll 18, and then into the nip N.
  • the web 11 is brought into contact with the surface of the chrome plated roll 13 before it enters the nip N.
  • the web 11 is then held against the surface of the roll 13 for an appreciable angular distance by the belt portion 12a and the web is then separated from both the belt 12 and the surface of the roll 13 and trained around a paper guide roll 22 and over another expander guide roll 23 and onto the dryer roll 33.
  • the web 11 coming off the dryer drum 20 has the optimum amount of moisture required for the compacting treatment. This optimum may vary between 20 to 50 percent moisture as the web 11 enters the apparatus 10.
  • the roll 13 has a smooth surface, preferably chrome plated.
  • the roll 13 is mounted on bearings 13a for rotation and is driven by a suitable source of power, such as a motor indicated diagrammatically at M.
  • the motor M is the driving power for the entire device 10.
  • the roll 13 drives the belt 12 primarily through pressure engagement at the nip N so that tension in the belt 12 is reduced at the nip N.
  • some power is required to drive the belt 12 around the various guide rolls, such as the rolls 14, l5, l6 and 17 and the point at which the belt 12 is driven (which in this case is at the nip N) is a point at which tension in the belt is reduced.
  • a lubricant shower 25 is provided just beneath the web 11 at the oncoming side of the nip N.
  • the lubricant shower 25 is a silicone shower but other release agents are suitable which applies a relatively small amount of liquid, in the form of a film, to the surface of the roll 13.
  • the roll 13 is heated, as shown here diagrammatically, by a suitable source of steam S fed axially into the roll 13 in the manner in which steam is fed into the usual paper machine dryer drum.
  • the steam maintains a relatively high temperature about 212 and up to 350 F. at the surface of the roll 13 so as to create a very thin steam film or cushion between the web 11 and the drum 13. This steam cushion assists in permitting relative sliding between the web 11 and the drum 13 (which is essential to permit the web to be compacted by the belt) and tends to soften some of the ingredients of certain types of paper.
  • the web 11 After leaving the compacting apparatus 10, the web 11 will pass through the dryer section 30 which includes conventional drying rolls 31-36, the web 1 1 first passing over drying roll 33 thence to roll 34 etc. as shown.
  • Felt dryer belts 37 and 38 are arranged upon guide rolls 39 and in contact with the respective dryer rolls 3l36 to assure the intimate engagement between the web 11 and the respective dryer rolls.
  • the moisture contained in the web is approximately 35 to 45% moisture by weight.
  • the moisture content of the web 11 will be approximately 7 to 15 percent of moisture by weight.
  • Reference numeral 40 indicates a size press arrangement for treating the dried compacted web 1 l in accordance with the present invention.
  • Web 11 first passes over guide rolls 41, 42 and therefrom proceeds between a nip formed by two counter-rotating size press rolls 43 and 44.
  • Nozzles 46, 47 control the starch metering valves 48, 49 in conduit 50, 51 which permit a metered quantity of a starch solution 52 to flow into the nip between size press rolls 43, 44.
  • Edge catch pans 53 collect the excess starch solution at each end of the nip.
  • the starch solution is supplied from a starch solution supply tank 54 having therein an agitator 56, starch in solution being drawn from the tank 54 through conduit 57 to the pump 58 which supplies metering valves 48 and 49.
  • a starch return pump 60 serviced by line 61 from catch pans 53 returns the starch solution via line 62 to the supply tank 54.
  • a solution of starch is applied under pressure to both sides of the web in accordance with varying percentages indicated below by way of specific examples.
  • the passage of the web 11 through the starch solution and between the rolls 43, 44 will be sufficient and will be so regulated as to the speed of application and the strength of the starch solution to permit and to cause impregnation of starch into both surfaces of the web 11 in accordance with a predetermined amount.
  • the weight of starch impregnated and deposited in the web will be from 1 percent to 10 percent by weight to the total weight of the web after drying in order to achieve good results, with optimums of different strength characteristics being obtained by impregnating starch in accordance with the percentage shown in FIGS. 4-9. During this process the moisture content of the web will increase from the 7 to 15 percent value at the outlet of the dryer section 30 to a value of 35 to 45 percent. v
  • Dryer section 66 contains a plurality of dryer rollers 67, 68, 69, 70, etc. about which pass dryer felts 71, 72 guided by rolls 73.
  • the dryer section 66 is similar in all respects to the dryer section 30 and the web 11 passing therethrough will lose the moisture imparted by the size press existing from the dryer section 66 with moisture content of approximately 5 to percent by weight.
  • FIG. 3 discloses an alternate embodiment of the invention wherein the same reference numerals have been used for similar parts as shown in FIG. 2.
  • the web 11 proceeds directly from the compactor 10 without first going through dryer section 30.
  • the web 11 contains approximately 30 to 40 percent moisture by weight prior to passing between the size press rolls 43, 44.
  • the web 11 contains this amount of moisture, lesser amounts of the starch solution will be caused to impregnate the web; however, a sufficient amount of starch in solution will impregnate the web to provide significant and beneficial results in regard to increasing tensile, burst and TEA characteristics, and may be expected to be in the order of approximately 50 percent of the improvement achieved with the configuration of FIG. 2.
  • the web 11 feeds into the dryer section 66 which reduces the moisture content of the web to a moisture level of 5 to 10 percent by Weight.
  • the advantage of the arrangement shown in section 3 is the use of asimgle dryer section to receive the web from the size press, although the moisture content of a web will ordinarily require a larger dryer sec tion to reduce the moisture content to acceptable levels.
  • FIGS. 2 and 3 it should be possible to obtain glazing of the paper web 11 by feeding the web downstream of the size press 40 around a single dryer roll provided that the starch solution when applied in the press 40 provides sufficient bonding of the web to the cylinder.
  • a pressure contact with the drying cylinder as shown for example in US. Pat. No. 3,362,869. The difference between the pressed arrangement and that shown in US. Pat. No.
  • 3,362,869 referred to above in describing the background of the present invention, is that the starch applied in the said United States Patent is a surface coating used to achieve adhesive bonding between the web and the dryer roll, whereas in the present invention the web becomes impregnated with starch on both sides to achieve the subsequent additional improvements of radically increased tensile, burst and TEA strengths.
  • the size press which includes the size press rolls for forcing the starch solution into both web surfaces.
  • Example No. 1
  • slightly converted starch should be superior to highly converted starches, particularly at high percentage levels of starch impregnation.
  • plasticized starch should be highly compatible'with the extensible qualities of compacted paper. This is not, however, in any way to suggest that the use of unconverted starch is undesirable, since the examples disclosed herein were made using starch in the highly converted form.
  • FIG. 7 show MD tensile results for potato and corn starch at different levels. Two different refininglevels were explored in each instance. Notethat whereas tensile gains for potato starch occur during the first 3% addition, increased tensile with corn starch continues to higher additive levels. Also it may be observed that the addition of 3% starch to compacted paper brings the tensile up to the level of the untreated (uncompacted) sample. This may be understood by recalling that the molecular structure of corn starch, having a more linear orientation than potato starch, creates a film with higher tensile strength.
  • a method for treating a compacted paper web to improve its tensile strength and stiffness while further improving its burst and TEA characteristics comprising the steps of: taking paper which is extensible by having been compacted without creping, thus'having improved burst, TEA and tear characteristics, and impregnating under pressure 'both sides of said web with a solution containing starch, while controlling the degree of moisture absorption from said solution by said web; and causing said web to be dried after impregnation with said starch solution; said web containing about Im 10% by weight starch.
  • an extensible paper web containing fibers which have been compacted without creping to provide improved stretch, tear, burst and TEA characteristics, said web further having impregnated under pressure into both surfaces thereof a predetermined amount of finely divided particles of starch to provide substantially increased tensile, TEA and stiffness properties, said web containing about 1 to 10% by weight of starch.
