Description
Technical field
The present invention relates to textile industry dyeing and finishing field, more particularly to a kind of tangerine valve type polyester-nylon complex fiber fabric imitates suede dyeing and finishing
Technique and its fibrillation agent.
Background technology
Superfine fibre is one of highest kind of technology content in differential chemical fibre, is not had with general fibre
Good characteristic, the diameter of fiber is small, large specific surface area, bending stiffness are low, feel particularly soft, can produce the height of soft matte
Shelves textile.However limited by spinneret processing technology, it is difficult to fibrous refinement be made by the method for changing spinning pore size, be
Superfine Denier fibre is obtained, composite fibre is produced using composite spinning technology, is handled using fiber opening process, you can is made ultra-fine
Fiber.
Composite fibre is mainly divided into as exfoliated and fabric of island-in-sea type.Tangerine valve fiber type is most important in exfoliated composite fibre
One kind, be with two kinds in chemical constitution it is entirely different, mutually incompatible polymers by composite spinning method make its
In section manufactured composite fibre is alternately arranged in tangerine petaloid.This composite fibre can be carried out by certain method at fibrillation
Different components is removed and superfine fibre is made by reason.
Tangerine valve type polyester-nylon complex fiber is due to the difference of two component structures and ingredient so that bonding force between compound interface compared with
It is weak, in the effect that external force and chemical reagent are encountered during post-processing, shrink and generate difference and crack.It is multiple that brocade is washed in influence
The factor of bonding and the stripping of two component of condensating fiber mainly includes：The performance of two kinds of polymer, spinning condition, cross sectional shape, yarn
Desizing degree of institutional framework and fabric of line and fabric etc..
Existing fiber opening method mainly has heat treating process, mechanical processing method and chemical method.At present, dye-works is existing various multiple
The fibrillation of condensating fiber realizes often through chemical fiber opening method, and chemical fiber opening method be divided into for acidic treatment, alkali process method with
And organic solvent method, and polyester-nylon composite superfine fibre, generally all using alkali decrement method, will be washed in the processing of Alkali reduction fibrillation
Brocade composite superfine fibre is arranged in lye, makes to wash comprehensive function of the bright and beautiful bicomponent filament yarn in liquid caustic soda, temperature, time and accelerating agent
Lower hydrolysis, terylene and polyamide fibre are cracked into single superfine fibre.Meanwhile as the concentration of caustic soda, temperature, time are continuously increased,
Fibrillation is more and more abundant, and the fiber number of superfine fibre attenuates, and monofilament quantity increases, fabric thickness increase, soft, water absorption,
It inhales solvent borne, dirt-removing power, wiping effect and reaches optimum state.But fibrillation is bigger, Alkali reduction is also bigger, and superfine fibre is not
Disconnected that hydrolysis occurs and constantly attenuates, therefore strength of filament becomes smaller, fiber stiffness, that is, fibrous fracture intensity declines, fabric thickness and gram
Weight also declines therewith, causes fabric construction loose, and the winding resilience of fabric and flat deflection decline, and strength also declines therewith, pole
Easy slippage and lose use value, can not realize fibrillation fully and the active balance of fabric intensity and thickness.
Polyester-nylon composite superfine fibre is due to its special structure and ultra-fine fibre diameter, so such as level dyeing of its dyeability
Property, color fastness etc. are very different with conventional fibre.1. the reduction influence on fastness is apparently higher than conventional fibre.Its main cause
It is analyzed as follows：1. pulp freeness is big, strong to Dye Adsorption ability, multiple-layer overlapped absorption is easily formed in fiber surface, with reference to
Power is weak, and dyestuff easily comes off；2. due to there is the presence of nylon fibre ingredient, polyamide fibre is contaminated on disperse dyes, and is contaminated on disperse dyes
Color fastness is poor afterwards, and under test condition of soaping, some dyes for being stained with fibrous inside easily move to fibre from fibrous inside
Dimension table face desorbs into dye liquor and causes color fastness poor；3. the influence of dyestuff thermophoresis.2. dyeing is not easy to contaminate even.Main cause
It is as follows：1. the fiber finer of polyamide composite filaments, large specific surface area, fiber are fast to the adsorption rate of dyestuff, it is irregular to easily cause absorption；②
Fiber is after chemistry and mechanical fibrillation, and fibre section irregular surface is coarse, thus adsorbance is more than conventional fibre；3. ultra-fine fibre
Dimension is more sensitive to the physics in processing damp and hot before dye and chemical action ratio conventional fibre, such as fibrillation, setting, once it is heated, by
Power or chemicals effect are uneven, will generate uneven dyeing.3. two-phase chromatography is uneven.Since disperse dyes can go up dye terylene
Dye polyamide fibre can be gone up again, be easy to cause appearance two be nested injustice the phenomenon that.4. depth is poor.Superfine fibre diameter very little, fabric table
Diffusing reflection in face of light enhances, therefore apparent colour phase modulation should weaken.Easy discoloration when 5. finished product is shaped.Because of superfine fibre specific surface area
Big and fiber is tiny, and fiber surface has many dyestuffs are impermeable to enter fibrous inside, and when high-temperature shaping easily distils or and silicon
Oil, which reacts, leads to discoloration.
In the actual production process of market, chemically composited fiber in order to obtain the feel style of imitative suede, such as flock suede or
Imitative peach face will pass through abundant fibrillation and handle, and then through roughing process, obtained superfine Denier fibre imitates suede style, this kind of fabric
Some typical technological problems of generally existing in subsequent dyeing and finishing technology.For example, light color is contaminated under (1) acid condition, dispersion dye
Expect easy dyeing flower；(2) depth is poor, as black dye is not deep；(3) dyefastness is particularly poor, such as suede leather with sea-island polyester filament suede, rubs
Rubbing fastness usually only has 1-2 grades；(4) it is excessive to be damaged serious or fabric loss of weight for fabric strength.These common problems always cannot
It effectively solves, particularly Fastness Problems, the wearability and use scope of extreme influence fabric.In addition to this, in market
Composite fibre flock suede or imitative peach face, will inevitably pass through roughing process, and some knitting warp class fabrics also need
To pass through plucking and cropping, technological process is elongated, and production cost greatly improves, while can influence after roughing process subsequent
The strength of uniformity and influence fabric during dyeing.
Invention content
The object of the present invention is to provide a kind of tangerine valve type polyester-nylon complex fiber fabrics to imitate suede dyeing and finishing technology and its fibrillation agent,
By the abundant fibrillation of two steps, the contradiction between fibre strength and velvet can be more preferably balanced, while remove napping step from；During dyeing
Basic dyeing is carried out with disperse dyes, by the reasonable selection of auxiliary agent, can realize that wash bright and beautiful two-phase chromatography uniform and improve each
The feel style of item fastness index and fabric, while remove acid dyes dye polyamide fibre technique from.
The present invention above-mentioned technical purpose technical scheme is that：A kind of tangerine valve type washs the compound fibre of brocade
