Description
Technical field
The present invention relates to a kind of preparation method of textile raw material, particularly spinning jet used in the preparation method of the high molten functional fibre of bamboo pulp and the method, belong to the textile product technical field.
Background technology
Regenerated celulose fibre mainly is the cotton pulp of making take cotton linter and timber, the viscose that wood pulp is produced as raw material.At present, usually produce viscose with viscose process, the processing step of the method as shown in Figure 1, but because there is following shortcoming in existing step:
(1) environmental pollution, cost height.Owing to usually use NaOH, carbon disulfide, sulfuric acid, zinc sulfate, sodium sulphate etc. in the viscose process production technology, the method toxicity is large, seriously corroded, pollution working environment, harm health of human body; And the environment protection treating expense has high input, and production cost is high, does not meet the demand of current low-carbon environment-friendly economy;
(2) easily produce static, viscose staple fibre intensity is low, fatigue durability is low.When the viscose staple fibre section configuration is circular, during full cortex, easily produce static during spinning, cause comb and parallel cotton fibers prior to spinning to be difficult for into net.The shortcomings such as when the viscose section is not circular, and when being not full cortex, it is low to exist intensity, and strength efficiency low (adding twisted filament to the powerful ratio of precursor intensity), fatigue durability are low;
(3) fiber of viscose process preparation is keeping the viscose premium properties simultaneously because adopting traditional viscose glue production technology, also has a shortcoming the same with common sticking school fiber unavoidably, and is hard such as inadequate, the lower steeping in water for reconstitution of wet strength, fabric is yielding.Bamboo pulp fibers contains residual sulphur, the harm health of human body.
For overcoming the use of defects and to save timber, linen-cotton material, utilize bamboo to begin to have had widely as the raw material cellulose fiber and use.
Bamboo is a kind of fast-growing cellulosic fibre raw material, grows in the area of warm moist, is about 2-3 growth period, and power of regeneration is strong after the felling, and the development and use bamboo can drive the economic development of bamboo grove industry, the useless ground of planting trees on barren hills.Bamboo is the regenerated celulose fibre raw material that has development prospect the new century, and what enjoy that people pay close attention to is that bamboo fibre has the natural antibacterial biocidal property, and has natural anti-ultraviolet function.At present some manufacturers are in research and development, when producing bamboo pulp fiber, have basically continued the viscose process production technology of cotton pulp, wood pulp.This technique is because using NaOH, carbon disulfide, sulfuric acid, zinc sulfate, sodium sulphate etc., and the method toxicity is large, and seriously corroded, pollution working environment, harm health of human body have destroyed the natural antibacterial biocidal property of bamboo fibre, natural anti-ultraviolet function.
And utilize novel solvent method, ionic liquid method to produce bamboo Lyocell fiber, also exist some technological difficulties to need to break through in manufacture method.For example: solve the problem of control bamboo fibre molecular weight in the bamboo Lyocell fiber manufacture process, reduce degraded as far as possible.In addition, the shortcoming that novel solvent method, ionic liquid method are produced bamboo Lyocell fiber is: when silk gum enters coagulation step from spinnerets behind the spray silk, filament easily occurs expanded outside spray orifice, affect the macromolecular horizontal integration of fiber and vertically be connected, thereby cause fiber strength low, drawability, fiber spinnability are poor.
In addition, be solidification liquid when selecting water, often can solidify poly-fast response.The inside and outside layer of filament fiber after solidifying conjunctiva do not slide, and molecular structure (film) is flexible poor, and filament is molecular injury structure (film) in drafting process, causes fiber strength low, and spinnability is poor.As the NMMO (NMMO+H that selects low concentration
2O) liquid is solidification liquid, and the filament fibrous outer conjunctiva after solidifying easily causes the dissolving damage; And the inside and outside layer of the filament fiber after solidifying conjunctiva do not slide, and molecular structure (film) is flexible poor, and filament molecular injury structure (film) in drafting process causes fiber strength low, and spinnability is poor.
In the actual production, easily produce static during the bamboo short staple spinning, blowing is difficult for rolling, and the comb and parallel cotton fibers prior to spinning of clear comb connection is difficult for into net.Before the bamboo staple fibre uses, need to add profit mixture humidification balance 24 hours in staple fibre, the weak strength efficiency of the cohesive force that causes spinning is low.
Therefore, be badly in need of at present according to the bamboo pulp own characteristic, develop leading in the world production technology, thereby produce well behaved bamboo pulp fiber.
Technical problem to be solved by this invention is take 100% bamboo pulp as raw material, utilizes functional latex and function to bathe pure mist technology, the high molten functional fibre of production bamboo pulp.Its product have natural sweet-smelling and have refresh oneself, the function such as antibiotic, sterilization, health care, anti-ultraviolet function.The high molten bamboo fibre of the present invention's preparation is through the regenerated cellulose fibrillation finished product (bamboo fibrillation G1000 series short fiber, middle length, wool type fiber) of technique post processing processing, pure spin or with other fiber blend, such as cotton, fiber crops, hair, viscose glue, wash etc., appearance white can make that fiber crops are refreshing, stiffening, woven exterior or the family's textile fabric with peach face style of the feel of wool.The high molten bamboo fibre of the present invention's preparation is through the active Cross-linked finished product of the regenerated cellulose of technique post processing processing (the active Cross-linked A1000 series of bamboo short fiber, middle length, long filament), appearance white, light is arranged, pure spin or with other fiber blend, such as cotton, silk, viscose glue, wash etc., can make the bright and clean knitted anderwear fabric of real silk style, " the unique sense of touch " with real silk reaches " the soft pendant that hangs down " characteristic.Wearability next to the skin is very good, has softness, comfortable, good permeability, smooth nice and cool, the characteristics such as drapability is good, and is stand wear and tear.
If add in the functional latex and can be the functional agents such as light emitting ionic preparation, antimicrobial silver ion preparation, medicinal liquor; Then can produce luminescent fibre, long-active antibacterial fiber, heath-function fiber.
If be incorporated as nanoscale look female powder (liquid), dying liquid formulation in the functional latex, can produce coloured regenerated cellulose filaments, staple fibre.
Summary of the invention
The object of the invention is to provide the spinnerets that uses in the manufacture method of the high molten functional fibre of a kind of bamboo pulp and the method, the technical scheme of this manufacture method comprises following operation: bamboo pulp is pulverized, dissolving and the high molten functional fibre spinning solution of preparation bamboo pulp, filter deaeration, spiral shell formula spray silk, solidify, post processing and manufacturing procedure, in course of dissolution, add functional latex, in spiral shell formula spray silk process, carry out simultaneously function and bathe pure mist operation, in process of setting, add the solidification liquid that is formed by ethanol, soft water.
