Definitions

• Tow. filament into staple arranges the staple in suitable fashion and produces a loosely spun yarn. commonly known as Top/ Unless the electrojstati'cdualities or the tow are cntrolled,-produc- 1 tics of a continuous top is impossible.
• This invention relates to the production of treated textiles and related materials. More specifically the invention. relates to the production of treated fibers, staple fibers, felts, threads, cords,
• morp-holine derivatives which act as textil'e antistatic agents are materials of the class A onion? R-N ⁇ orno Lower Alkyl wherein R is a long chain aliphatic radical containing from 11 to carbon atoms and A isan anion. Suitable derivatives may be formed by substituting within the above formula, the com.- pcnents suggested in Table I:
• Electrostatic charges were then induced by first rubbing 12 times with a glass rod to induce an electrostatic charge and then,after observation as indicated below, rubbing 12 times with a hard rubber rod to induce an opposite electrostatic charge. Observations of the charges induced were given electrostatic rating as indicated in Table II.
• the concentration of the quaternary ammonium derivative in the aqueous. solution. may vary over a wide range depending upon the method of application and subsequent treatment of the soaked textile. In general, it has been found that efiective static protection requires that there be deposited on. the textile at least 0.4% or the quaternary ammonium compound based on the weight of the treated textile. This level can be reached satisfactorily with aqueous concentrations as low as 2%. The upper limit is governed only by the solubility of the antistatic agent.
• the ratio of liquor to textile is not critical. An approximate ratio of 50:1 has been found convenient and employed in the examples.
• Example I Observed Static Rating Test Conditions Air dried, room temperature After 22 hours at 65 C After 96 hours at 65 C After 168 hours at 65 C After 240 hours at 65 C.
• Test Conditions Observed Static Rat Air dried, room temperature After 22 hours at 65 C After 96 hours at 65 0.- After 168 hours at 65 O After 240 hours at 65 C After 240 hours at 65 C. After 240 hours at 65 C.
• Example III An identical yarn treated in a manner such as described in Example I without the antistatic agent was rated as shown below:
• Example IV A nylon yarn identical to that of Example I was treated in the manner described in Example I employing a 5% solution of lauryl methyl morpholinium methosulfate. were obtained.
• nylon has been used to quantitatively demonstrate the value of the morpholine quaternary ammonium compounds as antistatic agents since it is highly susceptible to such static charges, it will be apparent to those skilled in the art that other textiles of natural and especially synthetic origin may likewise be treated.
• acetate rayon, Viscose rayon, Orlon (a polyacrylonitrile) cotton, wool, silk, glass, linen and the like have all been found amenable to the process. Satisfactory electrostatic elimination is obtained by treatment of these various materials as indicated below:
• a treated textile as wherein the textile is rayon.
• a process of treating textiles to render them anti-static which comprises treating said textile with an aqueous solution containing at least 2% of a compound of the formula defined in claim -1 defined in claim 1
