Abstract
This invention discloses a kind of oil applied to the polyester industry, its characteristic is that the oil is composed of the following component: (A) 5 ~ 70 weight % refining mineral oil; (B) 10 ~ 85 weight % polyatomic alcohol fatty acid esters; (C) 5 ~ 55 weight % copolymerizations ether; (D) 2 ~ 40 weight % fatty acid polyoxyethylene ester; (E) 1 ~ 15 weight % antistat; (F) 0.1 ~ 10%'s adhesion function improver. The oil can solve these defects of the present oil that both the heat resistance and the gluing function are bad. Since the heat resistance and the flatness are good, the smoke is few, the carbon build-up is few , waste thread rates is low in spinning handicraft; original silk brute force and modulus are good, maintained extension, breaking extension are low; The brute force loss in back handicraft processing is low , there is no color difference in the dyeing process.
Description
Technical field
The invention belongs to the chemical addition agent field, particularly a kind of oil agent used for polyester industrial filament.
Background technology
High speed development along with domestic economy, automobile, building, water conservancy, traffic, industries such as advertisement are soaring year by year to the consumption of polyester industrial filament yarn, its application percentage in industry will be brought up to 2010 25% from present 15%, the industry technology of State Economic and Trade Commission's promulgation is given priority in the project, fabrics for industrial use are classified as the textile industry new growth engines, terylene industrial will become one of industry of most active and potentiality in the coming years with long filament, because its market prospects are good, demand is big, the added value of product height, domestic many manufacturers are investing the polyester industrial yarn project energetically.High Modulus And Low Shrinkage type (HMLS) polyester industrial yarn wherein, because it has high-modulus, high strength, anti-flat spot performance is excellent, extension at break is little, characteristics such as Heat stability is good, it is first-selected desirable framework material as the meridian cord fabric, but it is with high content of technology, the production difficulty is big, and domestic manufacturer introduces technology or joint founding the factory.
In high temperature, high speed and the gum dipping process in the High Modulus And Low Shrinkage polyester industrial yarn spinning technique cohesiveness of terylene cord fabric and rubber or in dyeing and finishing technology the interaction etc. of dyestuff, finishing agent and finish finish has been proposed very high requirement.This product of finish company Development and Production of countries such as present Japan, the U.S., Germany, the finish of Japan this grease of bamboo company is mainly used in the polyester industrial yarn production technology of non-cord fabric, the flatness of finish is better, but the bond properties of cord fabric and latex is poor; The finish cohesiveness of Germany S.S company is strong, but its holding and poor heat resistance.Before and after spinning and the impregnation two technologies to finish require conflicting, improved the development difficulty of finish, existing finish or flatness, holding are good, but viscosity is big, the rate that oils height, have influence on behind the polyester industrial yarn dyeability in the process or extract out as the H of cord fabric, promptly dyeability, bond properties are poor; Be that bond properties is good, but the viscosity of finish is little, heat resistance and holding are poor, and it is big to show as being fuming of finish, and tow is dispersed, and intensity is low.Can not satisfy the requirement of the big and rate that oils of flatness, holding, viscosity simultaneously.Spinning factory meets the demands to use different finishes according to the different purposes of product, makes the finish product variety various, complex operation.Especially as the polyester industrial yarn of cord fabric, because the molecular structure of polyester fiber has determined its chemical inertness and has been difficult to performance with rubber adhesion, and existing being helpless to improve the bond properties of terylene cord fabric with finish, therefore normal activation processing or other method by fiber surface improves cohesiveness.Introduced a kind of finish that industry silks such as terylene, polypropylene fibre, polyamide fibre are produced that is used for as USP 5972497, form by the single, double ester of pentaerythrite or the single, double ester of pentaerythrite and antistatic additive, the flatness of this finish, excellent heat resistance, but convergence is poor, use as industrial silk oil agent, tow powerful low, the strength loss of tow is big behind the twisted weave, the poor adhesion of cord fabric.USP 5525243 disclosed finishes are by antistatic additive, emulsifying agent and polyvinyl alcohol are formed, antistatic additive mainly contains alkylphosphonic, quaternary amine, imidazoline etc., emulsifying agent mainly contains sorbitan monolaurate, the polyoxyethylene sorbitan monolaurate, the polyoxyethylene pelargonate, the polyoxyethylene caprylate, polyoxyethylene decylate etc., the characteristics of this finish are the confficients of static friction between fiber and the fiber, the coefficient of kinetic friction between fiber and the metal is low, holding between silk and the silk is strong, institute's spinning bundle is mainly as non-weaving cloth, as rope, fishnet, cord fabric etc., the shortcoming of this finish is to use as industrial silk oil agent, then the modulus of tow is low, powerful low, the bond properties of cord fabric and rubber is poor.USP 4469606 discloses a kind of high temperature resistant, oxidation resistant industrial silk oil agent and corresponding antioxidant etc., high temperature resistant, the antioxygenic property of finish have been emphasized, described finish is made up of alkyl polyoxyethylene polyalcohol, alkyl polyoxyethylene aliphatic acid, vegetable oil, antioxidant, the holding of finish, heat resistance and flatness are good, but be only applicable to the spinning technique that the emulsion state oils, and the modulus of tow and powerful low, the bond properties of cord fabric is poor.CN 1428480 disclosed finishes are made up of alkyl polyoxyethylene phosphate salt, alkyl polyoxyethylene ether or polyoxyethylene oleate, mineral oil, di-n-octyl sebacate, trimethylolpropane tris oleate etc., this finish has good flatness, heat resistance and wettability, is applicable to the civilian silk of the high-speed spinning one-step method terylene that oils with emulsion state production technology.But for convergence, heat resistance and even attached property requirement height, and flatness requires moderate industry silk, disclosed finish bad adaptability, show as and be not suitable for the spinning technique that oils with pure finish state, the holding of institute's spinning bundle is poor, powerful low, stretch surely and the disconnected height of stretching, poor as the bond properties that cord fabric uses.
