Abstract
The invention provides a completely biodegradable poly(butylene succinate) filament, and relates to the technical field of fibers. The filament comprises 100% of poly(butylene succinate). The filament provided by the invention overcomes the defects of poor permeability of polyester and nylon and easy aging of polypropylene, and has the characteristics of softness, comfort, easy caring and easy dyeing of natural fiber; the fabric woven from the fiber has excellent performances such as light weight, skin friendliness, breathability, green and environment-friendliness, especially the completely biodegradable property of the filament caters to the development ideas of soil protection and low carbon environmental protection promoted in the society.
Description
Technical field
The present invention relates to fibre technology field, refer to especially a kind of totally biodegradable poly butylene succinate long filament.
Background technology
Complete biodegradable plastics is the function keeping in using with existing plastics same degree; after use, can be the microbial actions such as occurring in nature bacterium, fungi, marine alga; finally resolve into the macromolecular material of the inorganic matters such as water and carbon dioxide; thereby prevent the pollution to environment; played the effect of soil protection and environment, so be called as " green plastic ".Complete biodegradable plastics can be divided into microorganism synthesis and degradation plastics, natural products degradative plastics and chemical synthesis degradative plastics from the composition of raw material and preparation method.
Chemical synthesis degradative plastics can be divided into aliphatic polyester and aromatic polyester.At present, aliphatic polyester is a family macromolecule material the most promising in biodegradation material.In aliphatic polyester, the combination property of PBS is best, and cost performance is reasonable, is the outstanding person in biodegradation material.And the raw material l of synthetic PBS, 4 succinic acid and l, 4 butanediols, not only can be obtained by petrochemical industry route approach, also can be obtained by Coal Chemical Industry Route or biofermentation route, have more environment protection significance and economic worth.In recent years more active to the research of PBS base degradative plastics both at home and abroad, but few for the preparation of the report of fiber to 100%PBS.
As Japanese You Nijika company has the heat-resisting core-skin monofilament polyester of biological degradability of high-tensile strength with the copolymer preparation that contains PBS and EGS ethylene glycol succinate, cortex polymer fusing point is lower than sandwich layer, and the monofilament making buries mass loss 3.6% after three months in soil.The compound long line of the concentric three-decker that PBS and EGS ethylene glycol succinate copolymer, poly adipate succinic acid ester or poly-sebacate are spun into by different proportion has also been invented by the said firm, it is said that this melt-spun fibre has good physical property, and can be degradable.
As Kimberly-Clark Worldwide Inc has developed a kind of hydrophilic binder fibers.This kind of fiber can be made by polyolefin core material and highly wettable aliphatic poly ester blend cot material cospinning.The composition of highly wettable aliphatic polyester blend comprises PBS, succinic acid-tetramethylene adipate copolymer, polycaprolactone polymer, the mixture of these polymer or the copolymer of these polymer, polybasic carboxylic acid, and wetting agent etc.The biodegradability of this hydrophilic binder fibers significantly improves, and is easy to processing.The disposable absorbent article that this hydrophilic binder fibers is made can be used for absorbing the fluids such as body fluid.
As publication number CN101597815A, 2009.12.9, " a kind of preparation method of poly butylene succinate fiber " disclosed, by spinning material poly butylene succinate and spinning material phase-change material micro-capsule, be (88～100) in mass ratio: (12～0), spinning process additive is (0.1～0.5) with the gross mass of poly butylene succinate and phase-change material micro-capsule in mass ratio: 100 carry out proportioning mixes; 500～800m/min spinning speed melt spinning; Drawing-off, HEAT SETTING, obtain poly butylene succinate fiber.
Above research or open source literature are all that PBS and other materials blend are prepared to fiber, totally biodegradable material PBS is prepared to long filament for melt spinning technology purely and also do not find at present relevant report.
Summary of the invention

Technical scheme of the present invention is achieved in that
A totally biodegradable poly butylene succinate long filament, wherein, the component of described poly butylene succinate long filament is 100% poly butylene succinate.
Above-mentioned totally biodegradable poly butylene succinate long filament can obtain by following preparation method, specifically comprises:
(a) dry poly butylene succinate section; Wherein baking temperature is 60-90 ℃, and the time is 6-12h;
(b) dried described poly butylene succinate section is carried out to melt spinning, obtain poly butylene succinate pre-oriented yarn POY, fully oriented filament FDY or high orientation silk HOY;
Spinning temperature: 160 ℃～270 ℃, biphenyl, 135 ℃～270 ℃ of extruder temperatures; Spinning speed: 1500～4200m/min;
(c) pre-oriented yarn is carried out to the processing of rear road, prepare poly butylene succinate long filament; Draw ratio: 1.2～1.85 times, 50～100 ℃ of deformation temperatures, winding speed: 450～650m/min.
The baking temperature of step of the present invention (a) is 60-90 ℃, bad lower than 60 ℃ of drying effects, and perishable higher than 90 ℃ of sections, performance changes.
As preferred technical scheme, described step (b) assembly formula is: metal sand 10/20 is netted half, then fills up with 250-300 mesh filter screen.
As preferred technical scheme, 20 ℃～26 ℃ of the cooling wind-warm syndrome of described step (b), wind speed 0.25～0.45m/s, oil nozzle position is apart from spinnerets 80～130cm.
As preferred technical scheme, described step (b) spinning angle 6～8 degree.
As preferred technical scheme, before described step (a) is dry, first carry out pre-crystallized.
Beneficial effect
Long filament of the present invention has overcome terylene and polyamide fibre gas permeability is poor, the easy aging shortcoming of polypropylene fibre, has comfortable, the easy nursing of natural fabric softness, chromatophilous feature; The fabric being made into this fiber, have the characteristic of the performance, particularly its totally biodegradable of good slim and graceful, pro-skin, ventilative, environmental protection, catered to the idea of development of the low-carbon environment-friendly that present society advocates.
