Definitions

• the invention also encompasses'the improved products obtained from this process.
• dichlorohydrins are employed in aqueous solutions dissolved in organic solvents such as aliphatic, aromatic hydrocarbons, etc., or in the anhydrous state.
• the alkaline agent is added directly to the vessel or apparatus wherein the treatment of the fibers is carried out, either immediately before or after the introduction of fibers into the vessel.
• the treatment of the yarns is performed before and/or after their stretching, for times which may vary from a few (at least 30) seconds to 2-3 hours, and at temperatures varying from room temperature to 10' below the melting point of the polymer.
• the alkaline agent e.g. sodium hydroxide
• Dichlorohydrin may be employed either in the pure form or while containing the normal impurities.
• (LH II 1 is prepared by introducing 64 g. (1 mole) of ethyleneglycol and 0.4 cc. of boron trifiuoride in 45% ethereal solution into a three-necked 500-cc. flask, provided with thermometer, stirrer and reflux condenser. The mass is warmed up to C. and 185 g. epichlorohydrin are added within two hours. The mass is kept in reaction for one additional hour, and then is cooled to room temperature.
• the diehlorohydrin thus obtained which has a titer of about 72%, is ready for use.
• the treated yarn is dyed with the fol-lowing dyes:
• Alizarine yellow 2 G (C.l. #14025) (C.l. mordant yellow 1) (acid) Red for wool B (C.l. #27200) (C.l. acid red 115) (acid) Alizarine red S (C.l. #58005) (C.l. mordant red 3) (acid) Alizarine blue SE (C.l. #63000) (C.l. acid blue 43) (acid) Acid black .lVS (C.l. #20470) (C.l. acid black 1) (acid) Setacyl bright blue BG (C.l. #61505) (C.l. disperse blue 3) (plastosol)
• the dyeings are carried out by maintaining the yarn in the bath containing 2.5% dye, based on the weight of fiber, at a fiber/bath ratio of I:40.
• the dyeings with acid dyes are carried out in the presence of 3% ammonium acetate (based on the weight of fiber) and 1% of a surfactant prepared by the condensation of ethylene oxide with p.cresol. 30 minutes after the boiling commences, 2%, based on the weight of fiber, of a 10% acetic acid solution is added in order to improve the rate of utilization of the bath.
• Dyeings with plastosoluble (dispersed) dyes are carried out in the presence of 2% (based on the fiber weight) of a surfactant.
• the yarns, after dyeing, are rinsed with running water and are intensely dyed, either with the acid or plastosoluble dyes. The light, washing and friction fastness'of these dyed yarns is shown to be entirely satisfactory.
• Example 2 1 Here and In the following examples the lntrlnsle viscosity has been measured in tetralin at C.
• the ture is 30 C.
• the yarn is allowed to remain in the e oxidation bath for 2 minutes.
• the roving is allowed to pass between rolls so that 2% of the pure opoxide is allowed to remain on the yarn.
• the collected roving is treated in an autoclave with steam at 120 C. for 1 hour.
• the yarn upon being dyed with the dyes of Example 1, gives intense, fast colors.
• Example 4 sodium hydroxide is added as in Example 4. The mass is then treated in hot air at 130' C. for 20 minutes, washed with water and dried. The treated yarn yields intense and fast colors upon being dyed with the dyes of Example 1.
• Example 7 2000 cc. of monochioroglyccrol and 5 cc. of a 45% ether solution of boron triiiuorlde are poured into a 3- liter, three-necked flask, provided with reflux condenser, thermometer and tap funnel. The mixture is heated at 95-400 C. and 610 cc. of epichiorohydrin are added over a period of about two hours so as to keep the temperature constant. When these additions are completed, the fiaslt is kept at 95-100 C. for two additional hours and the excess monochloroglyccrol is distilled off under vacuum.
• a process for improving the dyeing characteristics of fibrous materials such as filaments and yarns obtained by the extrusion of mixes of a polyaipha-olefin exhibiting a high content of crystallinity due to isotactic structure and 1-25%, based on the weight of said poiyolcfin, of a polymeric basic-nitrogen containing compound which process comprises contacting the fibrous materials in a bath with a glycol dichlorohydrin and a stoichiometric amount of a strong inorganic base to convert said dichlorohydrin into dicpoxide, at temperatures between room temperature and 10' C. below the softening point of the polymer, for a time varying from 30 seconds to 3 hours.
• polymeric basicnitrogen containing compound is selected from the group consisting of octadecylamine-epichlorohydrin-piperazine condensates, octndccyiaminc-epichlorohydrin-hexamethylenediamine condensates, isotactic crystalline polyvinyl pyridines and dihalogen derivative-diamine condensates.
• glycol dichlorohydrin is the dichlorohydrin of diglycidylether.
• glycol diehlorohydrin is the dichlorohydrin of the ethyieneglyeol diglycidyiether.
