Abstract
The present invention relates to a novel oil agent for polypropylene fine denier short fiber. The novel oil agent is composed of an alkyl phosphoric acid polyethylene glycol ester salt anionic surface active agent, a fatty alcohol polyoxyethylene ether non-ionic surface active agent, an alkyl silicone ether, an alkyl sulfate anionic surface active agent, polyhydric alcohol and deionized water. The oil agent is suitable for the polypropylene fine denier short fiber. The present invention has the main advantages that the oil agent has better permeability on the polypropylene fine denier fiber to make the polypropylene fine denier fiber not swollen and moistened, and good gliding property, antistatic property and cohesive property can be given to the fiber. Hand feel is soft and slip, and dynamic and static friction coefficients of fiber are appropriate, and the oil agent has good spinnability. The fiber successfully passes through every process step of a spinning factory, so the production quality of the polypropylene short fiber is greatly improved. The oil agent has the advantages of low cost and convenient use, has good solubility with water and is an ideal polypropylene fine denier short fiber oil agent.
Description
The present invention relates to the lubricated of a kind of and fiber, fabric and put relevant finish in order, especially, be specially adapted to improve fine-denier polypropylene, super fine denier staple fiber spinning process with to improve fiber spinnability relevant in the polypropylene spinning process.
The chemical fibre finish is meant an analog assistant that is applied in production of chemical fibre and the process, its effect is the frictional behavior of regulating fiber, prevent or eliminate accumulation of static electricity, give performances such as fiber is level and smooth, softness, make chemical fibre smoothly by spinning, stretching, operation such as spin, weave.
Finish component and amount thereof and fiber itself character, spinning technique are relevant with the product final use.Finish is except possessing flatness, antistatic behaviour, also should have other characteristic, as be easy to be applied (or being easy to remove), have good heat resistance, chemical stability, fibrous physics, chemical property there is not influence, guarantee to process behind the fiber and carry out smoothly, not residual at fiber surface, do not produce poison gas, peculiar smell, should have stability for storage, can with other fibre finish agent blend, fiber is not produced stain or changes fiber color, friction means to contact does not with it interact, and does not corrode machine part.
At present, the preparation medium that uses in prior art all is formulated by antistatic additive, smooth agent, emulsifying agent, auxiliary additive etc. usually, just by its fiber itself character, spinning technique is different with the product final use and different.US 4,624,793 (applying date: 1986.11.25) introduced a kind of lubricant composition of improvement in the patent application, it comprises the extended chain alcohol of emulsifying agent ethoxylation, antistatic additive ethyoxyl straight or branched alcohol phosphate sylvite or sodium salt, the hydroxylating bridging agent.Wherein fatty alcohol-polyoxyethylene ether is C11-15 straight or branched alcohol and 7-20 polyoxyethylene condensation product, and the phosphate of ethyoxyl straight or branched alcohol is to form with KOH or NaOH neutralization after lauryl alcohol and the 4.5 molecule polyoxyethylene esterifications again.This finish mainly is the finish that is used for the short silk of polypropylene, long filament, yarn, can also be as indirect food additives.Because the emulsifying agent of selecting for use is long carbochain ethyoxyl extended chain alcohol, to fine-denier polypropylene, especially super fine denier staple fibre wetting speed has tangible weak point in the above-mentioned finish preparation.
The objective of the invention is at above-mentioned finish weak point, develop a kind of novel finish that is suitable for fine-denier polypropylene, super fine denier staple fibre, to the thin dawn, superfine Denier fibre can be wetting quickly and evenly, and make fiber have flexibility, flatness preferably.
Finishing oil for fine-denier polypropylene staple fibres of the present invention is to be mixed by antistatic additive, smooth agent, emulsifying agent, additive, water to form.Selecting fatty alcohol phosphoric acid polyoxyethylene ester sylvite for use is antistatic additive, and alkyl silicone ether is smooth agent, and fatty alcohol-polyoxyethylene ether is an emulsifying agent, and alkyl sulfate salt or polyalcohol are additive.The weight proportion of antistatic additive, smooth agent, emulsifying agent, additive, water is 3～20%, 10～40%, 15～45%, 2～15%, 30～60%.
The above-mentioned antistatic additive fatty alcohol phosphoric acid polyoxyethylene ester sylvite of selecting for use is a kind of C10-18 alcohol phosphoric acid polyoxyethylene (2-6) ester sylvite, and its weight proportion is the best with 5～15% generally.
Smooth agent claims lubricant again, and its main effect is to reduce friction, and the protection fiber surface increases film strength, prevents corrosion.Smooth agent commonly used has mineral oil, synthetic or Natural ester compound etc.The present invention is through a large amount of experiment screenings, and selecting a kind of water-soluble organic silicon oxygen alkane for use is that alkyl silicon cave ether is smooth agent, and it can make fine-denier polypropylene, super fine denier staple fibre have better flexibility, flatness, and its general formula is:
Wherein R represents alkyl CH3, and R1 is
R2 is
M=3～10, n=3～15, x=3～10, wherein with m=4～7, n=5～8, x=3～6 are best.
In the production of polypropylene fibers technology, finish is a very important index to the wetting speed of fiber, especially for thin dawn, superfine Denier fibre key especially, the finish of short carbon chain fatty alcohol-polyoxyethylene ether after composite can reach fast evenly wetting effect to fine-denier polypropylene, super fine denier staple fibre during we found to quote.The general formula of selected fatty alcohol-polyoxyethylene ether is:
RO(CH2CH2O)nH
Wherein R represents C4～C8 straight chain alcohol, and n is 2～10.
The additive that the present invention selects for use is C10～C14 alkylsurfuric acid sodium salt or polyalcohol.Polyalcohol is propylene glycol, glycerol, two contract diethylene glycol (DEG), pentaerythrite, sorbierite.
The advantage of finish of the present invention is that polypropylene fibre or fabric are not had imbibition, especially the fatty alcohol-polyoxyethylene ether of short carbon chain is as emulsifying agent in selecting for use, make composite finish can reach fast evenly wetting positive effect to fine-denier polypropylene, super fine denier staple fibre, smooth agent, two immiscible components of antistatic additive are mixed with certain proportion, prevent that glue from connecting or muddiness, make the finish transparent and homogeneous, reach stability that improve to use lay up period, guarantee that finish does not have to be separated.The alkyl silicone ether that the present invention selects for use has been given fine-denier polypropylene, flatness that the super fine denier staple fibre is good, has improved the flexibility of fiber significantly.
The present invention is further elaborated for the following examples.
Below finish preparation in each example all be under 50～70 ℃ and stirring condition, to carry out.The finish of being prepared all can be used for fiber and fabric.
