Definitions

  • This invention relates to textile spinning machines, and more particularly to cots for spinning and card room rolls. While this invention will be described in connection with the making of spinning roll cots, it will be appreciated that this invention is also adapted for forming other rolls,. such as temple rolls, loom take-up roll coverings, and the like, commonly used in a variety of textile working machines.
  • Another object is to devise a spinning roller or cot having the fiber working surface characteristics of leather, such as sheepskin and calfskin, and which is more resistant to wear and has substantially no tendency to cause the fiber to adhere to the surface of the rolls.
  • Figure 1 is a perspective of a top spinning roller or cot with the covering partially broken away at one end;
  • Figure 2 is a section on the line 2-2 of Figure 1 looking in the direction of the arrows;
  • Figure 3 is a perspective of one end of the spinning cot sleeve
  • Figure 4 is a section on the line 44 of Figure 3 looking in the direction of the arrows;
  • Figure 5 is a section on the line 55 of Figure 3 looking in the direction of the arrows.
  • a spinning cot is that of being substantially static free and resistant to oils and greases.
  • Synthetic rubbers such as Neoprene and other similar butadiene polymers, such as methyl rubber, possess these essential properties but when using these materials in compounding cots, it was found that they were unsatisfactory because they would develop excessive eye brow and have a tendency to lap up the fiber being worked.
  • 'I'hiokol has extremely nigh oil resistance.
  • spinning cots made with this material also 'show the same defects of lapping and eye browing as Neoprene which is a polymer of 2- chlorobutadiene.
  • ingredients are compounded in the usual manner using suitable rubber mixing and compounding apparatus. After th materials are thoroughly incorporated they are molded and vulcanized to form a cot of the, desired shape.
  • the butadiene-acrylic acid co-polymer compound may be used in different amounts, preferably on the order of from 30% to 55% by weight of the composition.
  • the copolymer is vulcanized by heating with sulfur and the accelerator, similarly as in the case of natural rubber.
  • the hardness of the cots is preferably within Shore type A durometer. Further, in order to modify the hardness of the final product and its resilience. addition of carbon black, zinc oxide, clays and the like may be made as required to produce a cot having the desired properties.
  • the improved results are obtained by compounding the ingredients with butadiene-acrylic nitrile co-polymer and vulcanizing or curing the product. Good results can be obtained by em-' ploying a great variety of fillers, accelerators and different resins,
  • butadieneacrylic nitrile co-polymer has been found to be the most satisfactory, I do not preclude the use of other acrylic compounds.
  • the co-polymers of butadiene with acrylic acid esters or styrene may be employed.
  • the cots made from butadienearcylic nitrile co-polymer have a fiber working surface which is substantially equal to calfskin in spinning qualities.
  • the cat surface is dry and possesses a smooth, velvety feel. Further, it does not develop a gumminess on prolonged running, and in addition to the improved surface characteristics of rolls made from cots compounded in accordance with my invention, the cots are tough, resilient, resistant against oxidizing and possess a very low static build-up. Aside from these improved characteristics of my spinning cots they possess excellent abrasive resistance and are highly resistant to attack by oil, and are greatly su perior to similar cots made with chloroprene and other known oil resistant synthetic rubber substances.
  • the acrylic nitrile co-polymer of butadien in order to amount and substitution of different ingredients may be made in order to produce a product of the desired hardness, elasticity and frictional characteristics.
  • the ingredients will be compounded with the butadlene and acrylic nitrile co-polymer and molded to the desired form or shape, vulcanized, and, if required, the surface ground, buffed, abraded, or otherwise machined to give it the desired surface characteristics.
  • a textile machine unit for drafting fibers having a fiber contacting surface layer consisting of a vulcanized resilient composition including a vulcanizing agent such as sulphur comprising as an essential constituent a synthetic rubber composed of acrylic nitrile and butadiene co-polymer.
  • a vulcanizing agent such as sulphur comprising as an essential constituent a synthetic rubber composed of acrylic nitrile and butadiene co-polymer.
  • a textile machine unit for drafting fibers having a fiber contacting surface layer for contacting fibers consisting of a resilient composition including a vulcanizing agent such as sulphur comprising as an essential constituent a vulcanized synthetic rubber composed-of. butadiene-acrylic nitrile co-p01ymer admixed with 3.
  • a textile machine having a fiber contacting surface layer for contacting fibers consisting of a resilient composition comprising as an essential constituent a synthetic rubber composed of butadiene-acrylic nitrile co-polymer which is compounded with filler and resinous ingredients and vulcanized to form a surface layer which is resistant to abrasion and having substantially no tendency to cause sticking of the fiber to the same.
  • a textile machine 'unit for drafting fibers having a fiber engaging member vulcanized with a vulcanizing agent and formed of a composition which has been polymerized containing butadiene-acrylic nitrile co- -polymer as an essential constituent, with whiting and cumarone' resin incorporated in suificient amounts to give a substantially static free friction resistant wearing surface.
  • a textile machine unit for drafting fibers having a fiber contacting element comprising a synthetic rubber composition composed of butadiene-acrylic nitrile co-polymer, filler, resin and sulfur, which has been vulcanized with a vulcanizing agent such as sulphur to produce a product having an oil. resistant, substantially static free fiber working surface.
  • a vulcanizing agent such as sulphur
  • a textile machine fiber contacting element comprising butadiene-acrylic nitrile co-polymer compounded with substances serving to provide the required hardness and wearing qualities which has been vulcanized with sulphur, said fiber working element being substantially static free under ordinary working conditions.
  • a textile machine fiber contacting element provided with a cot composed of a vulcanized elastic composition comprising butadiene-acrylic I unit for drafting fibers which is substantially provided-with a cot composed of a polymerized elastic composition comprising butadien'e-acrylic nitrile co-polymer, resin, dibenzyl ether, zinc oxide and whiting admixed together and vulcanized with a vulcanizing agent to a relatively hard resilient body of uniform density which is wear resistant and is substantially free from a tendency to cause the fiber on which it is used to adhere to it under the usual working conditions.
  • a textile machine fiber contacting element provided with a surface layer formed of an elastic composition
  • an elastic composition comprising as a principal ingredient synthetic rubber selected from the group consisting of the co-polymers of butadiene-acrylic acid esters and acrylic nitrile, said synthetic rubber being compounded with addition agents .and vulcanized with sulphur to provide a relatively hard, resilient body of uniform density and having substantially no tendency to build up a static charge to cause adherence of the fiber under normal working conditions.
  • a textile machine fiber contacting roll mechanism having a covering cot composed of an elastic vulcanized composition which has been first polymerized, comprising :35 a principal constituent a co-poLvmer of butadiene and acrylic nitrile plus a ,vulcanizing agent, said co-polymer being compounded with fillers and other ingredients to. increase its hardness and wearing properties and provide a fiber-working surface substantially equal to calfskin and having no tendency to develop a static charge.
  • resilient body which has been polymerized, comprising as an essential constituent butadieneacrylic nitrile co-polymer, which has been vulcanized with a vulcanizing agent such as sulphur. 12.
  • a cot formed of butadie'ne-acrylic nitrile co-polymerand sulfur and vulcanized therewith.
