    Abstract: IT HAS BEEN FOUND THAT AN ANTISTATIC FIBER OF POLYAMIDE, POLYESTER, POLYUREA, POLYURETHANE OR POLYSULFONAMIDE CAN BE PREPARED BY UNIFORMLY DISPERSING BETWEEN ABOUT 1 PERCENT AND ABOUT 12 PERCENT BY WEIGHT OF A COMPOUND REPRESENTED BY THE FORMULA:

    H-(O-(CH2)2)Y-(O-CH(-CH3)-CH2)C-N(-(CH2-CH(-CH3)-O)D-

    ((CH2)2-O)Z-H)-(CH2)2-N(-(CH2-CH(-CH3)-O)A-((CH2)2-O)X-H)-

    (CH2-CH(-CH3)-O)B-((CH2)2-O)W-H

    WHERE A, B, C, D, W, X, Y, AND Z ARE EACH A WHOLE NUMBER AND THE TOTAL OF A, B, C, AND D IS BETWEEN 8 AND 850 AND THE TOTAL OF W, X, Y, AND Z IS BETWEEN 8 AND 1,000. THE COMPOUND HAS A MOLECULAR WEIGHT BETWEEN ABOUT 4,000 AND 135,000 AND THE ETHYLENE OXIDE MOIETY MAKES UP 10 OF 90% OF THE MOLECULAR WEIGHT OF THE COMPOUND.

    Abstract: IT HAS BEEN SUGGESTED THAT THE UTILITY OF SYNTHETIC FIBERS OF POLYAMIDE COULD BE INCREASED BY DISPERSING IN THE POLYAMIDE A MINOR PROPORTION OF AN ANTISTATIC POLYETHER COMPOUND DERIVED FROM THE REACTION OF AN AMINE HAVING AT LEAST ONE PRIMARY GROUP WITH AT LEAST ONE ALKYLENE OXIDE HAVING 2 TO 4 CARBON ATOMS, E.G., A COMPOUND REPRESENTED BY THE FORMULA:

    H-(O-CH2-CH2)Y-(O-CH(-CH3)-CH2)C-N(-(CH2-CH(-CH3)-O)D-

    (CH2-CH2-O)Z-H)-CH2-CH2-N(-(CH2-CH(-CH3)-O)A-(CH2-CH2-O)

    X-H)-(CH2-CH(-CH3)-O)B-(CH2-CH2-O)W-H

    WHERE A,B,C,D,W,X,Y AND Z ARE EACH A WHOLE NUMBER AND THE TOTAL OF A,B,C AND D IS BETWEEN 8 AND 850 AND THE TOTAL OF W,X,Y, AND Z IS BETWEEN 8 ANF 1,000. HOWEVER, WITH INCORPORATION OF THIS ANTISTATIC ADDITIVE IN THE POLYAMIDE, SERIOUS PROBLEMS HAVE BEEN ENCOUNTERED IN MELT-SPINNING DUE TO THE FREQUENT OCCURRENCE OF "DRIPS" OF THE MOLTEN POLYMER AS IT EMERGES FROM THE SPINNERET. IT HAS NOW BEEN FOUND THAT THE OCCURENCE OF SAID DRIPS CAN BE ELMINATED OF GREATLY REDUCED BY REACTING TH ANTISTATIC POLYETHER ADDITIVE WITH A COMPOUND OF THE FORMULA:

    (R-SO3)N-MENTAL

    OR A COMPOUND OF THE FORMULA:

    R-SO3-Z

    WHEREIN R IS SELECTED FROM THE GROUP CONSISTING OF ALKYL, CYCLOALKYL, ARYL AND ARYLALKYL, N IS A WHOLE NUMBER CORRESPONDING TO THE VALENCE OF THE METAL, AND Z IS SELECTED FROM THE GROUP CONSISTING OF HYDROGEN, AMMONIUM CATION AND SUBSTITUTED AMMONIUM CATION. MOREOVER, IT HAS BEEN FOUND THAT THE ANTISTATIC PROPERTIES AND DYEABILITY OF THE RESULTING POLYAMIDE FIBER ARE IMPROVED.

    Abstract: IT HAS BEEN FOUND THAT AN ANTISTATIC FIBER OF POLYAMIDE OR POLYESTER CAN BE PREPARED BY UNIFORMLY DISPERSING IN THE POLYMER BETWEEN ABOUT 1 PERCENT AND ABOUT 10 PERCENT OF A COMPOUND REPRESENTED BY THE FORMULA

    2,4,6-TRI(O=),1-(H-(O-CH(-R'')-CH2)T-O-CH(-R)-CH2-),3-(H-

    WHEREIN R AND R1 ARE INDEPENDENTLY AT EACH OCCURRENCE HYDROGEN, METHYL OR ETHYL AND R, S, AND T ARE INTEGERS FROM 31 TO ABOUT 200. PREFERABLY, THE COMPOUND IS A BLOCK COPOLYMER OF ETHYLENE OXIDE, PROPYLENE OXIDE AND TRIS(B - HYDROXYETHYL)ISOCYANURATE HAVING A MOLECULAR WEIGHT GREATER THAN 9,000, WITH THE ETHYLENE OXIDE MOIETY MAKING UP 10 TO 95 PERCENT OF THE MOLECULAR WEIGHT OF THE COMPOUND.

    Abstract: Filters for petroleum based liquids and the like are manufactured from heat-treated fabric composed of filaments prepared from blended composite fibers. In general the filter is characterized by light weight, corrosion resistance, compatibility with petroleum based liquids, low cost, dimensional stability, and resistance to shock and other mechanical abuse.

    Abstract translation: 用于石油基液体等的过滤器由由由混合的复合纤维制成的长丝组成的热处理织物制成。 通常，过滤器的特征在于重量轻，耐腐蚀性，与石油基液体的相容性，低成本，尺寸稳定性，以及耐冲击和其它机械性的滥用。
