Abstract: Filters for petroleum based liquids and the like are manufactured from heat-treated fabric composed of multicomponent 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: 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。

Abstract: CATIONIC DYEABLE POLYCAPROLACTAM IS PREPARED BY ADDING FROM 0.5 TO 2.0 MOLE PERCENT OF N-SULFOBUTYLHEXAMETHYLENEDIAMINE OR THE ALKALI SALT THEREOF WITH PREFERABLY 0.5 TO 2.6 MOLE PERCENT (ON TOTAL MOLES OF LACTAM) OF AZELAIC ACID, THE EXCESS OF FIACID OVER DIAMINE BEING PREFERABLY SUCH THAT THE POLYAMIDE HAS ZERO TO 80 MORE EQUIVALENTS TO ACID OVER AMINE PER 106 GRAMS OF POLYMER. ALSO, LESS THAN 30 EQUIVALENT OF AMINO END GROUPS ARE PREFERRED. IN THE PLACE OF AZELATE ACID MAY BE USED AN ALKALI SALT OF AZELIC ACID SUCH AS LITHIUM HYDROGEN AZELATE, OR MIXTURE OF IDSODIUM AZELATE WITH AZELAIC AID. THE DIALKYL ESTER SUCH AS DIMETHYL AZELATE OF AZELAIC ACID CAN ALSO BE USED. IN PLACE OF AZELAIC ACID OR ITS EQUIVALENTS AS MENTIONED ABOVE, THE SAME NUMBER OF EQUIVALENT OF DIMER ACID, FORMED BY DIMERIZATION OF OLEIC ACID, CAN NE USED. ALKALI CATION MAY ALSO BE ADDED BY ADDING ALKALI OXIDE, HYDROXIDE, CARBON OR BICARBONATE.
