Description
Technical field
The present invention relates to a kind of differential polyester staple fiber and production technology thereof, specifically is a kind of imitative goose down regenerated terylene superbhort fiber and production technology thereof.
Background technology
In the resisting cold articles for use, being used as the eider down of filler, is with the position under goose, duck oxter, the belly, gets the fine hair of its shape type.Eider down not only has good warmth retention property and soft property, do not have constriction and feeling of oppression and heat and has moisture absorption sweat discharging functions.Eider down is a kind of animal protein; Insulating power than vegetative fiber such as cotton etc. is high; The three-dimensional triangle skeleton structure of eider down itself can store a large amount of air, and air itself is a non-conductor, can resist therefore that outside The chill entered into the very flesh of the men and self body temperature runs off.But eider down belongs to natural prodcuts, so quality is uneven.
Terylene (being polyester fiber) is the important kind of synthetic fiber, and it is a kind of important textile raw material.With the terylene dacron fine-denier staple fibre that obtains after the processing that curls; Have outward appearance and the feel similar with eider down; And has the warmth retention property that quick-drying wet-permeable characteristic that eider down do not possess and eider down are complementary; Cost performance is high, is applicable to substitute the stuffing of eider down as high-grade bedding, home textile product etc.
Top-quality in the eider down is goose down, and its suede piece is big, and the plumage stalk is little, free from extraneous odour, and quality is good, the elasticity foot, warmth retention property is strong, has better hygroscopicity, having a good sweat property, and is dryer and comfortableer, and bulking intensity is higher.Goose down is the top product in quilt field, and the goose down resource-constrained contains the first-class white goose down quilt of goose down more than 75% all near 2000 yuan, and contains the superfine product white goose down quilt of goose down more than 90% often above 3000 yuan on the market.Therefore adopt the imitative goose down product of terylene production to have good economic benefit.
Down-like product (particularly imitative goose down) has the market potential, and existing down-like product fineness is basically at 1.5dtex.But imitative goose down production difficulty is big, and than higher, product fineness will be controlled at 1.2 dtex basically just can reach imitative goose down effect to the requirement of fineness, and common process is difficult to satisfy the regeneration superfine denier polyester production requirement of serialization.And existing conventional imitative goose down polyester staple fiber product length mainly concentrates on 32cm, 51cm, 64cm, when downstream manufacturers adopts it as stuffing, needs to adopt artificial semi-automatic filling, can't realize that machine automatically fills, and production capacity and efficient are lower.
Adopt the shorter terylene superbhort fiber of length can realize that the machine of stuffing automatically fills, improve production capacity and production efficiency, but mostly the terylene superbhort fiber is to adopt primary materials processing to become section back spinning to form at present, production cost is higher; It is that raw material is produced that regenerative PET material such as the polyester block material that produces in employing waste PET (being PETG) bottle sheet, sheet material, film and the polyester material production process, waste silk are also arranged, and to reduce cost, realizes resource reutilization.But because the regenerative PET material quality that reclaims is uneven; Its intrinsic viscosity and fusing point all have very big difference with the polyester slice that primary materials processing obtains; Also contain more non-polyester plastics impurity and moisture; Cause spinning quality adversely effected, performances such as the finished fiber outward appearance that obtains, feel are compared with real eider down and are had big gap.
And receive the restriction of process conditions, also exist in the production process fibre fineness and bulking intensity be difficult to reach imitative goose down effect, tensile fiber degree inadequately evenly, when stretching the shearing length of easy fracture, fiber not too all even accurately, be prone to produce shortcomings such as overlength and over-length fibre.
Summary of the invention
Technical problem to be solved by this invention is the defective that overcomes prior art; A kind of imitative goose down regenerated terylene superbhort fiber and production technology thereof are provided, and said production technology adopts the regenerative PET material to be raw material, and is cost-saved; Help environmental protection; The imitative goose down Regenerated Polyester Staple Fiber dimension that makes has outward appearance, feel and the warmth retention property that compares favourably with eider down, and the shearing length uniformity makes things convenient for downstream manufacturers realization machine automatically to fill.
For solving the problems of the technologies described above; The production technology of imitative goose down regenerated terylene superbhort fiber of the present invention; Its adopts regenerative PET material is raw material, successively through contain behind raw material pre-treatment, drum dried, melt spinning, cooling forming, the coiling silk fall bucket, boundling, drawing-off, curl, oil, make finished fiber after HEAT SETTING and the cut-out operation;
Said melt spinning operation is for to send dried regenerative PET material into the screw extruder heating and melting; The PET material of molten condition filters through manifold and measuring pump distributes; Become tow through spinnerets spray silk again; The screw rod of said screw extruder and manifold spin manifold temperature are 283 ℃-290 ℃, and said measuring pump confession amount is 1500-1700g/min, and spinning speed is 1350-1450 m/min;
The screw rod of screw extruder and manifold spin manifold temperature are controlled at 283 ℃-290 ℃ in the melt spinning operation; All on the temperature basis of 278 ℃-285 ℃ of common process, improve 5 ℃; This temperature range neither makes melt produce high temperature degradation, can improve the flowability of melt again, makes the as-spun fibre of ejection more even, quality is more stable; And have good high-elastic flatness performance, avoid the generation of overlength in the subsequent handling, over-length fibre.
Said cooling forming operation is that tow is passed through ring blowing cooling forming, and said ring blowing temperature is 20 ℃-21 ℃, and said ring blowing humidity is 65-85% rh, and said quench air velocity is 4.0 m/s-5.0 m/s, and a nothing oil silk inherent viscosity is 0.59-0.61 dl/ g;
