Abstract
The invention discloses a post-processing oiling agent for a polyester staple fiber. The post-processing oiling agent is an emulsion prepared by active ingredients and water, wherein the active ingredients contain A, B, C and D components. According to parts by weight, when A equals to 1.0, B equals to 0.2-0.8, C equals to 0.5-1.0 and D equals to 1.5-3.0 . When the polyester staple fiber oiled by the post-processing oiling agent is processed by pure spinning through an MVS (Murata vortex spinning) technology, oiling agent scales on main spinning parts such as vortex tubes and spindles in a spinning device are reduced obviously, the defect that the resultant yarn generates weak twist easily is effectively overcome, the cleaning period of the main spinning parts is prolonged and the production efficiency of spinning is improved greatly.
Description
Technical field
The present invention relates to process finish behind a kind of polyester staple fiber, particularly process finish behind the polyester staple fiber of spinning back processing employing air-jet eddy-current spinning yarn process.
Background technology
Air injection air vortex spinning (MVS) is the spinning technique of new generation of development on traditional air-jet spinning (MJS) basis, MVS is when resultant yarn, sliver is by the air-flow suction vortex pipe of negative pressure, and fiber is realized free-ended eddy current twisting under the effect of high speed swirling eddy in pipe.MVS has that speed is fast, output is high, flow process is short and lot of advantages such as row yielding height, though MVS yarn and MJS yarn all have the double-decker of core fibre and wrapper fibre, but the resultant yarn mechanism of MVS has determined fiber can realize tight looping, the ratio of MVS yarn outer wrapping fiber is much higher, hairiness number is but far below the MJS yarn, so single end strength is greatly improved.In theory; the adaptability of MVS is wider; can be used for processing multiple fiber such as chemical fibre, viscose, fiber crops or cotton and make pure spinning or blended yarn; but in fact MVS is carrying out can meeting with bigger puzzlement the pure man-hour that adds of spinning man-made fibre yarn; because usually the chemical fibre finished product must make fiber contain a certain amount of back through oiling and process finish; to give good antistatic behaviour of fiber and suitable flatness and convergence, make fiber in spinning and the back process such as weave and have better spinnability.But as the comparatively fine and close chemical fibre of materials such as terylene, the back processing finish major part that contains on the fiber is attached to the surface and forms one deck oil film, during spinning twisting, fiber under the effect of eddy current air-flow with vortex tube inwall and vortex tube in hollow spindle surface high-speed friction takes place, the oil film of fiber surface can be stained with and adhere on vortex tube inwall and the hollow spindle, and finish can progressively be piled up the dry finish foulant that forms after mixing a certain amount of dust.The finish foulant can cause the gas spray orifice on the vortex tube inwall to stop up on the one hand, make the swirl gas flow reduce the decline that causes twisting active force, can increase fiber on the other hand and when twisting, make the running resistance of high speed rotary, this causes resultant yarn easily to produce weak twist the most at last, and and then influence single end strength, when serious even make the yarn hole plug that draws of hollow spindle cause Yarn break.People adopt the cleaning frequency of critical pieces such as shortening vortex tube, spindle to solve this problem usually in the prior art.For example, when spinning pure Polyester Yarns, need usually the cleaning progress was once shortened to 3～5 hours once by general 2～3 days, this obviously greatly reduces the production efficiency of spinning.
Summary of the invention
Process finish after the invention provides a kind of polyester staple fiber, technical problem to be solved is that the fiber after oiling adopts the air-jet eddy-current spinning yarn process to spin to add man-hour, in the spinning equipment as be difficult for forming the finish foulant on the critical pieces such as vortex tube, spindle, thereby reduce the possibility of resultant yarn generation weak twist.
Below be the concrete technical scheme that the present invention solves the problems of the technologies described above:
Process finish behind a kind of polyester staple fiber, it is the emulsion that active ingredient and water are mixed with, and active ingredient contains component A, B, C and D.
Wherein:
Component A is the compound with following structural:
R in the formula
1Be the alkyl of C4～C12, m is 5～20 positive integer, and n is 50～200 positive integer;
B component is the compound with following structural:
In the formula: R
2Be the alkyl of C12～C20, x, y are 1～25 positive integer, and 5≤x+y≤30;
Component C is the compound with following structural:
In the formula: R
3Alkyl for C5～C11; Z is 3～18 positive integer;
Component D is the compound with following structural:
R in the formula
4Be the alkyl of C8～C18, M is K
+, Na
+Or NH
4 +,
In weight portion, when A=1.0, B=0.2～0.8, C=0.5～1.0, D=1.5～3.0.
R among the said components A
1Be preferably the straight chained alkyl of C4～C8; N is preferably 50～120 positive integer among the component A; R in the B component
2Be preferably the straight chained alkyl of C12～C16; R among the component C
3Be preferably the straight chained alkyl of C5～C8; R4 is preferably the straight chained alkyl of C8～C12 among the component D.
The proportioning of said components A, B, C and D is preferably: in weight portion, and when A=1.0, B=0.4～0.6, C=0.7～1.0, D=1.5～2.0.
The height that content of effective generally is controlled to be 8～60wt.% active principle content in the above-mentioned emulsion does not influence oil performance, because general requirement of the active principle concentration of finishing bathtray emulsion is lower than 5wt.% when finally using, lower content only increases carrying cost.
Key problem in technology of the present invention is that finish active ingredient is improved, not only have good antistatic behaviour, suitable flatness and convergence by the back processing finish of this formulated, and experimental result shows, this finish is processed finish after the film strength that fiber surface forms is better than general polyester staple fiber, when fiber after oiling and the friction of the object of metal material, be stained with the phenomenon that adheres to metal object surface and obviously reduce.
Good effect compared with prior art of the present invention is fairly obvious, the man-hour that adds of adopting the polyester staple fiber after processing finish in back provided by the invention oils to carry out pure spinning with MVS technology, obviously reduce as critical piece oil agent foulant such as vortex tube, spindles in the spinning equipment, effectively overcome the defective that resultant yarn easily produces weak twist, the cleaning frequency of main spinning parts prolongs, and spinning production efficiency significantly improves.
The invention will be further described below by specific embodiment.Because the generation of resultant yarn weak twist has reflected in the spinning equipment formation as critical piece oil agent foulant such as vortex tube, spindles sensitively, and the resultant yarn weak twist will directly influence the single thread ultimate strength, thus embodiment with the continuous spinning certain hour after the rate of descent of single thread ultimate strength estimate the invention effect.The rate of descent of single thread ultimate strength is defined as follows formula, and wherein the single thread ultimate strength is pressed GB/T 3916-1997 mensuration.
In the following formula, P
0The single thread ultimate strength of measuring when carrying out 1 minute for spinning, P
tThe single thread ultimate strength of measuring during for t for the continuous spinning time.
