  The present invention provides a topical method of using an ethoxylated alkyl phosphate ester additive on cellulose acetate tow bands as a plug maker processing aid. The present invention also provides a composition comprising an ethoxylated alkyl phosphate ester additive and cellulose acetate fibers.

Description

  The present invention relates to topical use of ethoxylated alkyl phosphate ester additives as plug maker processing aids for cellulose acetate tow bands. The present invention also relates to a composition comprising an ethoxylated alkyl phosphate ester additive and cellulose acetate fibers.

  The plug manufacturer's work transforms a bundle of cellulose acetate fibers (referred to as a “cellulose acetate tow band”) into a cylindrical plug containing fibers to form a filter encapsulated in a paper package. The basic functions of the plug maker include spreading the cellulose acetate tow band, loosening the crimped (crimped) filaments, applying a plasticizer, and forming into a cylindrical plug. To achieve these goals, the cellulose acetate tow band is processed through a number of air jets and rolls. The present invention enables the processing to be performed in a smoother and more uniform state.

  The use of an ethoxylated alkyl phosphate ester additive as a plug manufacturer's processing aid creates a clearly visible effect on the behavior of the filament when processed by the plug manufacturer. For example, the filaments are corrected for interaction with the roll without spreading too much. As a result, the following improvements can be obtained: 1) significantly narrowing the cellulose acetate tow band and reducing the width of the cellulose acetate tow band from varying (this is at the outlet of the plasticizer booth). Helps avoid impact on the guide and makes the cellulose acetate tow band more uniform during plasticizer application.); 2) Cyclic movement of the cellulose acetate tow band when leaving the plug maker roll 3) Increase the relaxation of the cellulose acetate tow band; 4) Reduce the tendency to roll wrap; 5) Reduce the variation in pressure drop at the maximum point; 6) Ability curve E) to a higher point; and 7) reduce the production of long filament lint.

  Working with energized static bars and passive static brushes reduces the static charge of the cellulose acetate tow band in plug makers and is called a long filament lint break Have been shown to provide beneficial results in reducing the deposition of the deposited filament pieces. One unexpected result of the present invention is the reduction in long filament lint as measured by the quantitative test method described below. Despite the obvious advantage of reducing electrostatic charge of electrostatic brushes, this benefit is achieved even when compared to electrostatic brushes. Since electrostatic brushes typically recorded a much greater decrease in electrostatic force, the expectation was that a reduction in long filament lint should show a proportionally greater improvement. . However, this has not been found to be the case, based on the long filament lint quantitative test described in the examples below.

  A second unexpected result was also obtained when using ethoxylated alkyl phosphate ester additives. There was an improvement in the processing of that material by the plug maker, and an improvement in the properties of the resulting cylindrical plug. The plug maker's air converging jets and rolls are purposely designed to force control the position and movement of the cellulose acetate tow band through the plug maker, including applying significant tension to the filament. . In light of the strong forces acting on the cellulose acetate tow band from the plug maker, it was unexpected that a modest change in the finish formulation drastically changed the behavior of the cellulose acetate tow band. In general, the composition of the material at the fiber surface may not have been previously known or imagined, such as that it can have a significant effect on the behavior of the filament as observed in the present invention. There wasn't. Both electrostatic force and frictional force can be affected by using ethoxylated alkyl phosphate ester additives.

The present invention provides a method comprising application of an ethoxylated alkyl phosphate ester additive onto the surface of a cellulose acetate tow band for use as a plug maker processing aid. The present invention also relates to a composition comprising an ethoxylated alkyl phosphate ester additive and cellulose acetate fibers. Ethoxylated alkyl phosphate ester additives have the chemical formula:
_{[CH 3 (CH 2) m} -O- (CH 2 CH 2 O) n -PO 3] - X +
And at least one ethoxylated alkyl phosphate ester. The term “ethoxylated alkyl phosphate ester (EAPE)” is a type of surfactant useful as an emulsifier, detergent and antistatic agent. The ethoxylated alkyl phosphate ester (EAPE) included within the scope of the present invention is an alkyl chain between C ₈ -C ₂₂ (m = 7-21) and a degree of ethoxylation of 2-30 mol per mole of alkyl chain Having an average degree of ethoxylation (n = 2 to 30). Preferably, the ethoxylated alkyl phosphate ester has an alkyl chain between C ₁₂ -C ₁₄ (m = 11-13), an average degree of ethoxylation per mole of alkyl chain (n = 4-12).

  Most preferably, the ethoxylated alkyl phosphate ester is an ethoxylated tridecyl phosphate ester potassium salt. “The Chemical Abstract” (CA) index name of ethoxylated tridecyl phosphate ester potassium salt is the potassium salt of poly (oxy-1,2-ethanediyl) -α-tridecyl-ω-hydroxy-phosphate ester and is registered by the CA The number is 68186-36-7. The potassium salt of ethoxylated tridecyl phosphate ester is typically 88% active with the balance being water. The average degree of ethoxylation is 6 moles of ethoxylation per mole of potassium tridecyl. Another range of ethoxylated alkyl phosphate esters and mixtures thereof that can be used is m = 7,8,9,10,11,12,13,14,15,16,17,18,19,20,21 and n = 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, and 30. m and n may be any combination, or a mixture thereof. These ethoxylated alkyl phosphate esters may be left as free phosphate esters (X = H) but are typically neutralized with Group 1A metal hydroxides to form phosphate ester salts. (X = Na, K). However, any metal compound that can neutralize ethoxylated alkyl phosphate esters to form phosphate salts can also be used.

These ethoxylated alkyl phosphate esters are typically solubilized in water for ease of handling. A preferred ethoxylated alkyl phosphate ester configuration for use in the present invention is neutralized with KOH (X = K) and comprises an alkyl chain between C ₁₂ -C ₁₄ (m = 11-13) Having an average degree of ethoxylation (n = 4-12) between 4 and 12 moles of ethoxylation per mole of chain.

  The purpose of topical application is to supply ethoxylated alkyl phosphate ester additive to the surface of the fiber on the cellulose acetate tow band. This application can also be performed by any means known in the art. Typically, this application can be carried out by applying the liquid directly, using rolls or lube tips, by use of a spraying device, or by other means, resulting in an ethoxylated alkyl phosphate ester. The additive will remain mainly on the surface of the fiber. Application with an existing fiber finish containing an oil-in-water emulsion is the preferred feeding method. The ethoxylated alkyl phosphate ester additive inside the fiber appears to provide very little benefit as a processing aid. In one embodiment of the invention, typical application levels of ethoxylated alkyl phosphate ester additives are optimally 250-1000 ppm by weight, based on dry fiber. In another aspect of the invention, another range is 100-3000 ppm. If the ethoxylated alkyl phosphate ester additive level is less than 10 ppm, minimal benefit would be expected. Load levels greater than 5000 ppm will still provide the benefits of the present invention, but will have little additional benefit.

  In one embodiment of the invention, the application of the ethoxylated alkyl phosphate ester additive is by means of an oil-in-water emulsion. An emulsion is a stable mixture of two or more immiscible liquids held in suspension by a material called a small percentage of emulsifiers, especially oil-in-water emulsions where water is a continuous phase. And an emulsion in which the water-immiscible substance is a dispersed phase. The term “oil” applies to a wide range of substances with completely different chemical properties, from animal and vegetable oils to essential oils. Animal and vegetable oils are generally composed of glycerides of fatty acids; mineral oils are composed of hydrocarbon mixtures, and essential oils are primarily volatile terpenes. The mineral oil used in the present invention is meant to indicate a petroleum paraffin distillate mainly composed of linear hydrocarbons. The preferred method of application in the present invention is from emulsified mineral oil (petroleum paraffin fraction of petroleum) to which the ethoxylated alkyl phosphate ester additive described in the present invention is added at the level detailed herein. This is due to the constituted oil-in-water emulsion.

  In other embodiments of the invention, the cellulose acetate fiber does not have the superabsorbent polymer in each of the previously mentioned embodiments.

  In another embodiment of the present invention, the cellulose acetate fiber is free of gloves in all previous embodiments.

  The invention can be further illustrated by the following examples of preferred embodiments thereof, which are included solely for the purposes of illustration, and unless otherwise indicated. Of course, it is not intended to limit the scope of the invention.

  Ethoxylated alkyl phosphate ester additives were added to a standard formulation of acetate tow finish. Aqueous oil-in-water emulsions were prepared at ethoxylated alkyl phosphate ester additive levels to provide about 0, 250 and 500 ppm by weight of ethoxylated alkyl phosphate ester additive based on dry fiber weight. No problems were recorded regarding the stability of the emulsion.

  A total of 14 samples of cellulose acetate tow bands were prepared as shown in Table I using different finishes as described above. The operating conditions for cellulose acetate tow band production were kept constant except for the difference in finish. The finish was applied directly to the filament at the exit from the spinning cabinet. Analytical measurements on a sample of cellulose acetate tow band after crimping demonstrated that the target level of finish was successfully applied to the cellulose acetate tow band.

  Various tests were performed on these samples using plug makers “Hauni® AF3” and “Hauni® AF2”. “Hauni® AF3” operated at 600 m / min, while “Hauni® AF2” operated at 400 m / min. Since the difference in performance due to the observed treatment level was clearer the higher the operating speed, the experiment carried out with “Hauni® AF3” is described in this example. The need for processing aids such as ethoxylated alkyl phosphate ester additives appears to be greatest in machines operating at higher speeds.

  The experiment was performed with a “Hauni® AF3” plug maker with and without a passive electrostatic brush. The electrostatic brush includes conductive bristles that are arranged in a rectangular arrangement and grounded in the vicinity of a cellulose acetate tow band for the purpose of dissipating electrostatic charges. The first electrostatic brush was placed between a pretension roll and a slow threaded roll. The electrostatic brush was placed relatively far from the meshing of the rolls to avoid the brush bristles coming into contact with either the rolls or the cellulose acetate tow band. The second electrostatic brush was installed between a low speed threaded roll and a fast threaded roll.

  The summary of the experimental run statistics listed in Table I is summarized in Table II to show more clearly the effect of the treatment level of the ethoxylated alkyl phosphate ester additive on the two brush configurations. The electrostatic charge was measured above the center of the cellulose acetate tow band at the outlet of the plasticizer booth. The use of 250 ppm ethoxylated alkyl phosphate ester additive showed a significant change that reduced the electrostatic charge by 13.7 kV. Doubling the addition to 500 ppm resulted in a further 5.8 kV drop, indicating that it was close to reducing the effect. The use of an electrostatic brush reduces the electrostatic measurement to 27.1 kV regardless of the treatment level of the ethoxylated alkyl phosphate ester additive.

  Long filament lint deposits include collections of filaments having a length range of about 0.25-30 cm long broken at various locations in the plug maker. The problems with long filament lint are: sudden unraveling of filament mass from the collection point, leading to rod quality defects or machine failure; machine failure due to roll winding; Management and maintenance work to keep the equipment clean. A plug maker operator uses a subjective rating scale that observes the deposition of filaments on the surface of the machine during operating hours. The best score corresponding to very few long filament lints is 1, while higher values up to a score of 10 indicate progressively higher amounts of lint.

  The use of 250 ppm by weight of ethoxylated alkyl phosphate ester additive reduced the long filament lint to 1.1 units, which showed a significant change. The use of 500 ppm by weight of ethoxylated alkyl phosphate ester additive reduced long filament lint to 1.6 units compared to the control. The use of electrostatic brushes improved the rating to 1.9 units for all treatment levels of ethoxylated alkyl phosphate ester additive.

  The second measure of long filament lint included quantitative measurements obtained by taking an electronic image of the plug maker surface at a specified time throughout the lint test. Image analysis was performed to quantify the proportion of long filament lint accumulated in the machine. This quantitative measurement provides a more objective and detailed measure of long filament lint. The use of 250 ppm by weight of ethoxylated alkyl phosphate ester additive reduced the quantitative ratio of long filament lint deposition from 5982 to 4132. By using 500 ppm by weight of ethoxylated alkyl phosphate ester additive, the same value was reduced to 3621 showing a 39% reduction. The average level of quantitative long filament lint was 3877 in the presence of ethoxylated alkyl phosphate ester additive.

  The electrostatic brush reduced this value from 5982 to 4526 with 0 ppm ethoxylated alkyl phosphate ester additive. When using an electrostatic brush in the presence of an ethoxylated alkyl phosphate ester additive, the average level of quantitative long filament lint was 3634. The reduction in long filament lint in the presence of ethoxylated alkyl phosphate ester additive was roughly the same (3877 vs. 3634) with or without an electrostatic brush. Despite the fact that electrostatic brushes have a much greater impact on electrostatic charge readings, the magnitude of improvement in long filament lint is greater than ethoxylated alkyl phosphate esters than using electrostatic brushes alone. The use of additives is greater (3877 vs. 4526). This provides some evidence that the electrostatic charge in the region of the roll gap is an important factor. It is also pointed out that other mechanisms that affect the behavior of the filaments and cellulose acetate tow band may also exist, such as by fiber-roll friction.

  There is a hypothesis that the electrostatic charge acts on the filament to push it outside the cellulose acetate tow band and lead to a force that interacts with the surface of the plug maker. Interaction with the roll appears to be a particularly strong factor that causes the filaments to spread beyond the plane of the cellulose acetate tow band. When impacting a plug maker's surface or plasticizer, the filaments that spread out from the cellulose acetate tow band can easily break and lead to long filament lint formation.

  Several quantitative observations were made to reveal the improved behavior of cellulose acetate tow bands resulting from the use of ethoxylated alkyl phosphate ester additives as processing aids. One effect is to make the cellulose acetate tow band narrow and firm. The width of the cellulose acetate tow band operating at 0 ppm of the ethoxylated alkyl phosphate ester additive tended to fluctuate over time and often hit the plasticizer booth exit guides 12 inches apart. At 250 ppm and 500 ppm, the cellulose acetate tow band was narrowed to a few inches and the width of the cellulose acetate tow band was reliably stabilized. Part of the visible lint improvement described above is due to the fact that the cellulose acetate tow band no longer collides with the guide, which usually serves as the deposition site for the long filament lint. A further processing advantage appears to be improved plasticizer application uniformity due to the firm behavior of the cellulose acetate tow band throughout the plasticizer spraying operation.

  A second important change in the behavior of cellulose acetate tow bands, which indicates improved processability, involves the interaction of cellulose acetate tow bands with plug maker rolls. The plug maker “Hauni® AF3” has four rolls from start to end: pre-tension roll, low speed thread roll, fast threaded roll and delivery roll. ). At a treatment level of 0 ppm ethoxylated alkyl phosphate ester additive, it can be observed that the cellulose acetate tow band circulates in and out of the main plane defined by the plug maker's passage through the plug maker. As the cellulose acetate tow band emerges from the roll gap formed by the two rotating rolls, the cellulose acetate tow band tends to remain in contact with or close to one of the rolls. This pulls the cellulose acetate tow band outside the main plane described above. Eventually, the roll on the downstream side exerts a force on the cellulose acetate tow band so as to separate the cellulose acetate tow band from the gap between the rolls. The appearance of this phenomenon can be summarized by saying that the cellulose acetate tow band comes and goes back and forth. The flickering movement is undesirable because it involves a non-uniform force applied along the cellulose acetate tow band that would cause the removal of the crimp from the cellulose acetate tow band to vary. Following the high speed yarn roll, an important step called relaxation must occur, where the fibers must correct the crimps temporarily removed by stretching by the roll. The previously described circulation behavior appears to change to achieve the short-term relaxation achieved to be plug-misaligned.

  One of the most severe plug maker processing conditions, including the interaction between the cellulose acetate tow band and the roll, involves roll wraps that inevitably lead to machine failure. In roll wrapping, the interaction between the cellulose acetate tow band and the roll is not overcome by pulling the cellulose acetate tow band downstream. Instead, the cellulose acetate tow band sticks to the roll and rotates many times. The interaction of cellulose acetate tow bands and rolls in plug makers is a composite that includes several different types of forces. One important force includes the difference in air pressure caused by the driven roll.

  The second force includes the generation of electrostatic charges due to contact between the roll and the fiber and subsequent detachment. When the oppositely charged surface begins to detach, an electric field is generated that includes a force that acts to refuse detachment. Based on the static charge measurement method described above, this mechanism appears to be one of the factors contributing to the efficacy of ethoxylated alkyl phosphate ester additives.

  The third set of forces includes the frictional force between the roll and the cellulose acetate tow band. Both the amount of fiber finish formulation and the chemical species present have a dramatic effect on the frictional force of the treated fiber. It is possible that the ethoxylated alkyl phosphate ester additive affects the frictional behavior of the cellulose acetate tow band and thereby its behavior with the roll. The smoother the movement of the cellulose acetate tow band through the plug maker, the longer the capacity curve and the less the change in pressure drop at the highest point. The highest point is here defined as the operating point that, if adjusted to further increase the amount of tow in the plug per unit length, above which the plug maker reliably fails. The advantages of the above ethoxylated alkyl phosphate ester additive appear to expand this operating point. The data in Table II shows that treatment with the ethoxylated alkyl phosphate ester additive appears to improve the rate of change in pressure drop by 12%.

  The invention has been described in detail with particular reference to preferred embodiments thereof, but it will be understood that variations and modifications can be effected within the spirit and scope of the invention.
