Definitions

  • This invention relates to roll covers or cots for textile fiber drafting machines such as spinning, drawing, and roving frames and to aprons and other drafting elements used in the textile industry.
  • the invention will be con sidered specifically with reference to cots, for such drafting elements are widely used and are typical of many different forms of fiber drafting surfaces.
  • An object of the present invention is to provide a textile fiber drafting element having an improved drafting surface.
  • Another object of the invention is to provide a textile fiber drafting element including butadiene-acrylonitrile synthetic rubber having an improved drafting surface.
  • the butadiene-acrylonitrile elastomer 2 there is compounded with the butadiene-acrylonitrile elastomer 2 to 70 parts, and preferably to 25 parts, of a compatible surfactant for each 100 parts by weight of elastomer.
  • the surfactant is preferably one which is essentially fully compatible with the elastomer at textile mill-operating temperatures and in the proportions used so as not to sweat out during service.
  • the nonionic surfactants are preferred, although the compatible cationic surfactants may be used.
  • Example I ice Parts by weight Butadiene-acrylonitrile rubber e. g. "Chemigum Animal glue 50.0 Curing agent, e. g. sulfur 10.0 Curing accelerator .5 Activator, e. g. zinc oxide 5.0 Plasticizer 8.7 Pigments and fillers 15.3
  • Curing agent e. g. sulfur 10.0 Curing accelerator .5 Activator, e. g. zinc oxide 5.0
  • Nonionic surfactant e. g. polyethylene glycol (400) monolaurate
  • the product has a Shore A hardness of 78-88 after vulcanization for 50 minutes at 300 F.
  • the compounding and curing of the composition may be carried out generally in the conventional manner as disclosed in Baymiller Patent 2,450,409, for example, with the nonionic surfactant being added in the manner disclosed in my application Serial No. 427,344, filed concurrently herewith and entitled Method of Making Textile Fiber Drafting Elements Containing Animal Glue and a Surface-Active Material to insure proper distribution of the animal glue throughout the compound.
  • Example II Parts by weight Butadiene-acrylonitrile rubber e. g. Chemigum N4" 100.00 Curing agent, e. g. sulfur 3.00 Curing accelerator 1.75 Activator, e. g. zinc oxide 5.00 Pigment (blue) 1.00 Coarse nonreinforcing filler, e. g. limestone 75.00 Nonionic surfactant e. g. polyethylene glycol (400) monolaurate 20.00
  • the product may be compounded in a conventional manner and when cured for 50 minutes at 300 F. will have a Shore A hardness of 55-60, considerably softer than the composition of Example I.
  • This product may be prepared in the same manner as Examples I and II and when similarly cured will have a Shore A hardness of -75.
  • the cot composition of the following example illustrates a composition including cork granules:
  • Example IV Parts by weight Butadiene-acrylonitrile rubber e. g. Chemigum Nonionic surfactant e. g. polyethylene glycol (400) monolaurate 20.0
  • This composition may be prepared and processed similarly to Example I and when cured for 50 minutes at 300 P. will have a Shore A hardness of 7585. It will be especially'resistant to eyebrowing because of the presence of cork 'granules distributed through the mixture lt will be lap resistant even when drafting the more diflicult synthetic "fibers for the polyethylene glycol (400) monolaurate substantially improves lap resistance.
  • Example V Parts by weight Butadiene-acrylonitrile rubber e. g. Paracril Animal glue 50.0 Curing agent, e. g. sulfur 10.0 Curing accelerator 2.0 Activator, e. g. zinc oxide 5.0 'Plast'icizer 18.7 'Pigment and filler 15.3 Lubricant, e. g. carbowax 4000 15.0 Cationic surfactant, e. g. amide of polyamine stearate (Nopcogen 18S) 2.0
  • Curing agent e. g. sulfur 10.0 Curing accelerator 2.0
  • Activator e. g. zinc oxide 5.0 'Plast'icizer 18.7 'Pigment and filler 15.3
  • Lubricant e. g. carbowax 4000 15.0
  • Cationic surfactant e. g. amide of polyamine stearate (Nopcogen 18S) 2.0
  • Example VI Parts by weight Butadiene-acrylonitrile rubber e. g. Chemigum N-l" 100.0 Curing agent, e. g. sulfur 10.0 Activator, e. g. zinc oxide 5.0 'Plasticizer 18.7 Pigment and filler 15.3 Lubricant, e. g. carbowax 4000 5.0
  • Cationic surfactant e. g. alkyl biguanidine- (Soromine BSA-60% solids)
  • This stock may be prepared in the same manner as the other examples, provided extreme care is exercised to avoid scorching in factory production due to the presence of a substantial quantity of the cationic material.
  • the lap resistance of the product is satisfactory to permit use of the composition for most textile fiber drafting services, being better than a conventional Chemigum stock.
  • nonionic and cationic surfactants when they are compounded with butadiene-acrylonitrile rubber and the mass is vulcanized provide a new fiber drafting surface.
  • certain members of the class will perform in an outstanding manner in one composition while others may similarly perform in other compositions but will be less efiective in still other compositions.
  • nonionic surfactants there are many nonionic surfactants available, and in the development of the present invention a large number have been secured and compounded with butadieneacrylonitrile rubber and then evaluated for textile drafting uses.
  • the following is a list of commercially available nonionic surfactants which are compatible with butadiene-acrylonitrile copolymer rubberlike materials in the proportions desired for use in accordance with this invention and at mill-operating temperatures and have given significant improvement in textile drafting qualities when compounded with butadiene-acrylonitrile rubber generally as described in the foregoing examples and compared with similar compounds which do not include the nonionic material.
  • Onyxol 336 A fatty alkanolamide.
  • DSpers-W Condensation product of a polyglycol, fatty acid and sod. sultosuccinio acid.
  • Airosol B Fatty Aikylol amide condensate.
  • Detergent JV-1653 A fatty acid amine condensate.
  • Michelene DS Alkyl nmldo alcohol.
  • Michelene DLD- Fatty acid amide ester.
  • Victamul 20 Organic esters of phosphate.
  • a secondary amide of lauric acid A secondary amide of lauric acid.
  • Triton X-45 Alkyl aryl polyether alcohol Triton X-45 Alkyl aryl polyether alcohol.
  • Triton B-1956 Modified phthalic glycerol alkyd resin.
  • Ground limestone is a suitable filler which works well with the other compounding ingredients in equipment commonly used in drafting element production.
  • Other useable inorganic fillers are barytes, calcium carbonate, and calcium silicate. Organic fillers may also be used.
  • the proportioning of the surfactant on the weight of the rubber may be varied over a Wide range, from about 2 to 70 parts for each 100 parts of the butadiene-acrylonitrile rubber.
  • the cationic surfactants generally will be used in lesser amounts than 70 parts because of their tendency to unduly accelerate the cure of the synthetic rubber, resulting in scorching. Substantially no improvement is noted with an amount less than 2 parts. It is preferred to use at least parts to 100 parts of the synthetic rubber. Optimum results are achieved with to parts, such amount being in most instances significantly better than 10 parts per 100 of the synthetic rubber.
  • nonionic surface active agents are preferred.
  • the drafting elements made in accordance with Examples II, III, and IV which contain nonionic surfactants are particularly resistant to eyebrowing, i. e., a tendency for waste fiber pulled from the roving by the cot and not carried rearwardly of the clearer board by the cot to accumulate at the front of the clearer board in a bunchlike formation.
  • Example IV which contains cork granules possesses a significant advantage in this regard over Examples II and III, these two compositions being better than Example I which in itself is an excellent material for drafting surfaces.
  • Examples II, III, and IV possess a high degree of lap resistance and better than normal eyebrow resistance for a lap-resistant product-normally, the lap-resistant products are poor in eyebrow resistance and vice versa. With the present invention it is possible to attain both characteristics to a high degree in the drafting surface.
  • a textile fiber drafting element having a working surface characterized by its lap resistance comprising a vulcanized composition of rubberlike butadiene-acrylonitrile copolymer containing as a permanent ingredient uniformly dispersed in the copolymer, in the proportion of about 2 parts to about 70 parts for each parts by weight of the copolymer, a material selected from the group consisting of nonionic and cationic surface-active materials containing long chain hydrophobic molecular groups and mixtures thereof which imparts in said proportion lap-resistance to the element.
  • a textile fiber drafting element in accordance with claim l in which the surface-active agent includes a cationic surfactant.
  • An eyebrow-resistant roll cover for textile fiber drafting in accordance with claim 1 having cork granules distributed through the mixture and exposed at the working surface.
  • a fibre-contacting element for use in processing textile fibres and composed of an oil-resistant synthetic rubber composition containing as a permanent ingredient, in the proportion of at least two parts by weight to one hundred parts by weight of synthetic rubber, a recognised textile fibre dressing material which is an organic surface active agent containing long-chain hydrophobic molecular groups and imparts in said proportion an anti-licking character to the element.
  • a fibre-contacting element in accordance with claim 12. in which the surface active agent ingredient is present in the proportion of the order of twenty parts by weight to one hundred parts by weight of synthetic rubber.
  • a textile fiber drafting element having a working surface characterized by its lap resistance comprising a vulcanized composition of ruberlike butadiene-acrylonitrile copolymer containing as a permanent ingredient uniformly dispersed in the copolymer, in the proportion of about 10 parts to about 25 parts for each 100 parts by weight of the copolymer, a material selected from the group consisting of nonionic and cationic surface-active materials containing long chain hydrophobic molecular groups and mixtures thereof which imparts in said proportion lap-resistance to the element.
  • a textile fiber drafting element having a working surface characterized by its lap resistance comprising a vulcanized composition of rubberlike butadiene-acrylonitrile copolymer containing animal glue and as a permanent ingredient in the proportion of about 2 parts to about 70 parts for each 100 parts by weight of the copolymer, a material selected from the group consisting of nonionic and cationic surfaceactive materials containing long chain hydrophobic molecular groups and mixtures thereof which imparts in said proportion lapresistance to the element.
