Abstract
The polyamide cord high-speed spinning oil is made up by using the chemical components of polyoxyethylene-polyoxypropylene block type polyether, alkyl phosphate methyl salt, caprolactam oxyethyl compound, soluble cerium (cesium and rubidium) organic compound and defoaming agent MPO, etc. through a certain compounding process according to a certain proportion. As compared with existent technology it possesses the advantages of reducing pollution and end breakage rate, raising antistatic property, obviously improving fibre strength and dip penetration and making fibre oiled amount less.
Description
The present invention relates to a kind of synthetic fiber spinning oil that is used for textile industry, be particularly suitable for the dyeing and finishing and the chemical surface treatment of polyamide cord high speed, belong to surfactant manufacturing technology field.
The polyamide cord line is the framework material in the rubber.But because the hygroscopicity of polyamide fiber self is little, poorly conductive, coefficient of friction is big, damaged lacks cohesive force simultaneously so easily produce static in the postorder process, and the collection property is also poor.Therefore often lousiness is many for product, the end breakage rate height.And then causing the product cost height, production efficiency is low.Usually adopt in the prior art and it is carried out surface treatment by composite spinning oils that forms of chemical raw material such as smooth agent, antistatic additive, collecting agent, emulsifying agents, to improve fibre strength and impregnation intensity, reduce lousiness and end breakage rate, satisfy the technological requirement in the fiber production.But see with present actual operating position and still to have tangible mass defect; With commercially available German SYNEX-371L type spinning oil is example, and its attached oil mass is big, and when fuel feeding place temperature is 195～202 ℃, winding speed is 2900～3000 meters/timesharing, and attached oil mass reaches as high as 1.4-1.5%, not only the cost height, also cause environmental pollution; The second, antistatic property is poor, and lousiness is many, and the end breakage rate height is the highest even more than 12-15%, and especially in summer, fiber and impregnation intensity obviously reduce, and have a strong impact on product quality.
Goal of the invention of the present invention is to release a kind of attached oil mass of fiber that can reduce at above-mentioned the deficiencies in the prior art just, reduces cost, and avoids unnecessary environmental pollution; Reduce end breakage rate simultaneously, improve antistatic property, fibre strength and impregnation intensity, make the scope of application such as drawing speed and specification requirement condition wideer, and obviously improve and stabilized product quality the polyamide cord high speed spinning oil solution of enhancing productivity.
Purpose of the present invention can be achieved by the following technical programs: polyamide cord high speed spinning oil solution is except comprising solubility rubidium or cerium, caesium organic compound beyond the region of objective existence, also include polyoxyethylene and polyoxypropylene block type polyethers mixture with 20: 80 to 80: 20 weight ratios, alkyl phosphate first salt (PK), the caprolactam ethoxylate, defoamer MPO; The percentage by weight of its each component is:
Polyoxyethylene/polyoxypropylene block type polyethers 60～90%
Alkyl phosphate first salt 5～20%
Caprolactam ethoxy compound 0.8～1.5%
Solubility cerium, caesium, rubidium organic compound 5～15%
Defoamer MPO 0.1～0.3%
Preparation method of the present invention adopts prior art and technology, is about to above-mentioned various mixing of materials, heats up about 80 ℃, and stirring gets final product.If add a small amount of preservative agent, can make extended pot life of the present invention reach 24 months.
The present invention's advantage compared with prior art is conspicuous: the first, reduced attached oil mass, reduced production cost, avoided unnecessary environmental pollution and produce lousiness, the broken end problem that thing causes that accumulate therefrom on drawing roller.Test shows can make the attached oil mass of polyamide long fiber remain on 0.8-1.2% under the stabilised quality prerequisite.Reason is to contain among the present invention the atactic polyether of 60-90%, has the permeability and the surface of good tension force of height.It has adapted to polyamide fiber and has had surface micropore layer, the characteristics of the saturated long filament of chemical modification, high surface energy not.Give full play to its protection fiber surface, reduced the effect of coefficient of friction.The second, reduce the friction between fiber and the metal and the lousiness and the end breakage rate that cause, improve antistatic property and the fibre strength and the impregnation intensity of fiber, make it have more applicability.This is owing to contain a certain amount of caprolactam ethoxy compound in the finish.The polyamide long fiber is along with finish adheres to and infiltration, and its thing of ethyoxyl thing amine is improved fibre strength to the processing of crystalline solid and chain overlap joint, forms salient point at fiber surface simultaneously, from and improved impregnation intensity.Result of the test shows, after the influence of rejecting various unfavorable factors such as technology, additive, equipment, electrical equipment, operation, whenever fall 100 barrels with equal conditions, end breakage rate of the present invention only is 4.3-5%, two steps were spun fibre strength and reach 7～7.8%, and impregnation intensity also obviously improves.It can not only adapt to the technology of polyamide fiber and high speed PET spinning (3500 meters/minute) and ask.Also can under with 4 times of water-reducible conditions, be used for low speed polyamide fiber (450 meters/minute) spinning draft process.The conduction type antistatic additive alkyl phosphate first salt that adopts as for the present invention aligns at fiber surface, its hydrophilic group and hydrone form hydrogen bond, make fiber surface form hydrophilic monomolecular film, can increase the electric conductivity of fiber undoubtedly, make it have good antistatic behaviour.
Embodiment: the present invention adopts the polyoxyethylene/polyoxypropylene block type polyethers (also can adopt different molecular weight polyethers such as ethylene oxide/propylene oxide block copolymer) of multiple different molecular weight to make smooth agent, phosphate first salt (or receive salt) is antistatic additive, and other has a small amount of defoamer, bactericide and stabilizing agent can adapt to the requirement of high, low speed spinning technique.Also have good anti-cigarette ash performance, convergence and obvolvent performance simultaneously.When being used for polyamide fiber long filament high speed spinning, do not dilute, directly use.As low speed or other melt spinning, then use to get final product by the dilution of different cultivars technological requirement.For example polyamide fiber continuous yarn spinning speed is 450 meters/minute, dilutes and can use with four times water.As being used for the high speed PET spinning, 3300 meters/minute of spinning speeds, oil concentration are 12%.
In the middle of actual production, can select following concrete cooperation ratio for use according to actual conditions, as embodiment 1:
Polyoxyethylene/polyoxypropylene block type polyethers 60%
Alkyl phosphate first salt 20%
Caprolactam ethoxy compound 1.5%
Solubility cerium organic compound 15%
Defoamer MPO 0.3%
Wherein polyoxyethylene and polyoxypropylene block type polyethers are the form of mixtures existence with 20: 80 weight ratios.
Embodiment 2:
Polyoxyethylene/polyoxypropylene block type polyethers 75%
Alkyl phosphate first salt 12.5%
Caprolactam ethoxy compound 1.15%
Solvable living cerium organic compound 10%
Defoamer MPO 0.2%
Wherein polyoxyethylene and polyoxypropylene block type polyethers are to exist with 50: 50 weight ratio mixtures.
Embodiment 3:
Polyoxyethylene/polyoxypropylene block type polyethers 90%
Alkyl phosphate first salt 5%
Caprolactam ethoxy compound 0.8%
Solubility caesium organic compound 5%
Defoamer MPO 0.1%
Wherein polyoxyethylene and polyoxypropylene block type polyethers are the mixture existence with 80: 20 weight ratios.
If add a small amount of preservative agent to the present invention, then period of storage can extend to two week of dilution in 24 months the back not stratified, do not precipitate.As about 30 ℃ of cold, finish muddiness, intensification, stir, still can use.
