Definitions

  • This invention relates to a method of producing a substantially waterless self-emulsifiable chemical softener composition. More particularly, it relates to a method of producing a substantially waterless self-emulsifiable chemical softener compositions useful for treating fibrous cellulose materials, such as tissue paper webs.
  • the treated tissue webs can be used to make soft, absorbent paper products such as toweling, napkin, facial tissue, and toilet tissue products.
  • Armak Company of Chicago, Illinois, in their bulletin 76-17 (1977) disclose the use of dimethyl di(hydrogenated)tallow ammonium chloride in combination with fatty acid esters of polyoxyethylene glycols to impart both softness and absorbency to tissue paper webs.
  • quaternary ammonium compounds such as the well known dialkyl dimethyl ammonium salts (e.g. ditallow dimethyl ammonium chloride, ditallow dimethyl ammonium methyl sulfate, di(hydrogenated)tallow dimethyl ammonium chloride etc ). are effective chemical debonding agents. Unfortunately, these quaternary ammonium compounds are not hydrophilic. Applicants have discovered that the chemical softening compositions of the present invention enhance both softness and absorbency rate of fibrous cellulose materials.
  • dialkyl dimethyl ammonium salts e.g. ditallow dimethyl ammonium chloride, ditallow dimethyl ammonium methyl sulfate, di(hydrogenated)tallow dimethyl ammonium chloride etc .
  • the ultimate users of the chemical softening composition simply dilute the mixture with a liquid carrier (i.e., water) to form an aqueous dispersion of the quaternary ammonium compound / polyhydroxy compound mixture, which is then added to the papermaking furnish.
  • a liquid carrier i.e., water
  • the homogenous mixture of the quaternary ammonium compound and the polyhydroxy compound can exist either in a solid state or in a fluid state before being dispersed in the aqueous media.
  • the mixture of the quaternary ammonium compound and polyhydroxy compound is diluted with a liquid carrier such as water to a concentration of from about 0.01% to about 25% by weight of the softening composition before being added to the papermaking furnish.
  • the transition from the X ⁇ to the X ⁇ crystal occurs at 27°C in DHTDMAMS instead of 47°C as in DODMAMS.
  • calorimetric data indicate that several crystal ⁇ Lam phase transitions occur in DHTDMAMS rather than one as in DODMAMS. The onset temperature of the highest of these transitions is 56°C, in good agreement with the X-ray data.
  • Analysis of the amount of treatment chemicals used herein or retained on tissue paper webs can be performed by any method accepted in the applicable art.
  • wet strength additives typically result in paper products with permanent wet strength, i.e., paper which when placed in an aqueous medium retains a substantial portion of its initial wet strength over time.
  • permanent wet strength in some types of paper products can be an unnecessary and undesirable property.
  • Paper products such as toilet tissues, etc., are generally disposed of after brief periods of use into septic systems and the like. Clogging of these systems can result if the paper product permanently retains its hydrolysis-resistant strength properties.
  • manufacturers have added temporary wet strength additives to paper products for which wet strength is sufficient for the intended use, but which then decays upon soaking in water. Decay of the wet strength facilitates flow of the paper product through septic systems.
  • the substantially waterless self-emulsifiable chemical softener composition of (5) can be pre-mixed (steps 1-5 above) at the chemical supplier (e.g. Sherex company of Dublin, Ohio) and then economically shipped to the ultimate users of the chemical softening composition where it can then be diluted to the desired concentration.
  • the chemical supplier e.g. Sherex company of Dublin, Ohio
  • the embryonic wet web is transferred from the photo-polymer wire, at a fiber consistency of about 15% at the point of transfer, to a photo-polymer fabric having 0.87 cells per mm 2 (562 Linear Idaho cells per square inch), 40 percent knuckle area and 0.23 mm (9 mils) of photo-polymer depth. Further dewatering is accomplished by vacuum assisted drainage until the web has a fiber consistency of about 28%.
  • the patterned web is pre-dried by air blow-through to a fiber consistency of about 65% by weight.
  • the web is then adhered to the surface of a Yankee dryer with a sprayed creping adhesive comprising 0.25% aqueous solution of Polyvinyl Alcohol (PVA).
  • PVA Polyvinyl Alcohol
  • the fiber consistency is increased to an estimated 96% before the dry creping the web with a doctor blade.
  • the doctor blade has a bevel angle of about 25 degrees and is positioned with respect to the Yankee dryer to provide an impact angle of about 81 degrees; the Yankee dryer is operated at about (800 fpm, feet per minute) 244 meters per minute.
  • the dry web is formed into roll at a speed of (700 fpm) 214 meters per minutes.
  • the fiber consistency is increased to an estimated 96% before the dry creping the web with a doctor blade.
  • the doctor blade has a bevel angle of about 25 degrees and is positioned with respect to the Yankee dryer to provide an impact angle of about 81 degrees; the Yankee dryer is operated at about (800 fpm, feet per minute) 244 meters per minute.
  • the dry web is formed into roll at a speed of (700 fpm) 214 meters per minute
