Description
Technical field
The invention belongs to flocked fiber preparing technical field, and in particular to a kind of preparation method of dermis flocked pile artificial leather.
Background technology
Electrostatic spinning be in high-voltage electrostatic field by electricity handle well chopped fiber orientation plant in the base material for scribbling adhesive
Surface, then through preliminary drying, the process such as bake and be prepared.Electrostatic spinning has its unique superiority as Surface-micromachining process, can
With the flocking on the various three-dimensional and non-cubic base material such as fabric, paper, plastics, rubber, timber, glass, metal and ceramics,
Be widely used in numerous industries such as automobile, stationery, packing business, decoration, instrument and instrument, and with wear-resisting, lubricious, sealing, sound insulation,
Heat-insulated, anti-scald, anti-corrosion and the function such as antifouling, it is both beautiful and practical.
Flocking in the market is made using chemical fibre more, and product is single, and feel is poor, without natural fur
Smooth, fine and smooth, high-grade feel, it is difficult to meet the market demand of diversification.And leftover pieces and waste material in leather processing procedure, it is difficult
Fur clothing is prepared with secondary use again, its secondary use is prepared into dermis flocked pile, has opened up the application of animal fur waste material
Scope.
Chinese patent ZL201110146760X provides a kind of preparation method of leather flocking short fiber, by corium corner
Flocking corium chopped fiber is made through screening the techniques such as color separation, high frequency cleaning, low-temperature grinding, spraying colouring and airflow drying in material.Should
Method turns waste into wealth corium leftover pieces, but its chopped fiber percentage of impurity is higher, and the protein residue of animal's leather, which is difficult to remove, to be done
Only, and the dyeing of made flocking chopped fiber is uneven, and dye stability is poor.
Fur is precious garment material with leather.Tanned animal fur is typically referred to as fur, and by adding
The smooth surface or matte dermatotome of work processing are referred to as leather.Fur is the preferable material of warm wear, takes its warming, light, durable, and
Magnificent noble quality.Leather can obtain various appearance styles after dyeing is handled, very popular.In recent years, hair
Skin turns into popular main flow with leather wear.But for FUR GARMENT because its raw material sources is limited, clothing difficulty is higher, and price compared with
Height, and the personalized needs of people can not be met, it is therefore desirable to develop a kind of FUR GARMENT alternative materials of high emulation.
The content of the invention
The invention provides a kind of preparation method of dermis flocked pile artificial leather, technique is simple, and production efficiency is high, clothing difficulty
It is low, dermis flocked pile artificial leather is obtained through electrostatic spinning using leather flocking short fiber, can highly imitate fur coat texture and
Feel, cost is cheap, meets a variety of design requirements more, has large market prospect.
The technical proposal for solving the technical problem of the invention is：
A kind of preparation method of dermis flocked pile artificial leather, comprises the following steps：
(1) pre-process：Animal fur waste material progress color separation, screening and impurity elimination are obtained into species fur.By animal wool dermatome
Classified according to species, the difference at position, screened, so that its quality is close, ensure made same batch dermis flocked pile fiber
Quality is identical.
(2) aerosol hydro-peening：The animal fur that will be pre-processed through step (1) is clean through aerosol hydro-peening, then true through 40-60 DEG C
Sky drying；
(3) crush, alkali cleaning：By the animal fur cleaned up obtained by step (2) after pulverizer crushes, compound alkali is added
After liquid handles 2-4 hours at 60-80 DEG C, regulation PH is 7, filters while hot, obtains chopped fiber A, then will be washed, dried.
The leather component in animal fur particle is decomposed by the present invention special compound alkali lye so that fur is rapidly separated, and point
It is good from effect, then the filtered animal wool that obtains is chopped fiber A.
(4) dye：Chopped fiber A is added in dyeing cylinder, then dye solution is added toward dyeing in cylinder, is heated to 50-
70 DEG C, after 3-5 hours are dyed in insulation, tryptophan and color fixing agent are added, continues isothermal holding after 30 minutes, regulation PH is 7, is taken
Go out chopped fiber A, after 90-100 DEG C is dried in vacuo 30 minutes, be cooled to room temperature, then through washing 3-5 times, then at 40-60 DEG C of vacuum
Drying obtains required leather flocking short fiber.
(5) leather flocking short fiber obtained by step (4) is made into flocking, acrylic acid makees adhesive, and artificial leather makees base fabric,
Carry out 3-5 electrostatic spinning and obtain tufted artificial's leather fabric, then at 110-130 DEG C of baking 5-8 minute, in heat treatment on forming machine
Afterwards, then with blower fan by flocking is remained blow away, then through combing to obtain required dermis flocked pile artificial leather.
Preferably, the compound alkali lye described in step (3) is made up of following parts by weight component：20-30 part bicarbonates
Sodium, 5-10 parts ethylenediamine, 3-5 parts sodium metasilicate, 1-3 parts aminophylline, 1-3 parts alum and 30-40 part water.Compound alkali lye is using a variety of
Weak base compounding forms, and alkaline matter can be dissolved in the material of water with the fat in animal's leather and albumen qualitative response generation, so that
Obtain animal's leather to decompose so that fur quick separating.According to highly basic processing, then animal wool can be caused to degrade, it is smooth to influence its
Degree.Sodium metasilicate in compound alkali lye can form layer protecting film on animal wool surface, further reduce alkali lye and it is damaged, alum
The compliance and glossiness of animal wool can be increased.
Preferably, the mass ratio of the animal fur and compound alkali lye described in step (3) is 1：10-15.
Preferably, the dye solution described in step (4) is made up of following parts by weight component：20-30 parts are acid cloudy
Ion pigment, 30-40 parts water and 1-3 part cosolvents.
It is further preferred that described acidic anionic pigment be selected from acid red, acid black, acid blue, acid ash, acid golden yellow and
At least one of acid brown.
It is further preferred that described cosolvent is sodium cetanesulfonate, polyoxyethylene sorbitan monooleate or dehydration
Sorbitan fatty acid ester.
Preferably, the color fixing agent described in step (4) is cetylpyridinium chloride or brocide.Acid
Property anionic pigment be one of the dyestuff commonly used in animal skin, but its shortcoming is that dyeing is uneven, and dyeing firmness needs to be carried
It is high.Tryptophan in alkalescent, can be reacted with acidic anionic pigment as a kind of alkaloid, while can be with animal wool table
The protein in face crosslinks reaction so that dyeing firmness is improved.From cetylpyridinium chloride or bromination 16
Alkyl pyridine makees color fixing agent, can be reacted with acidic anionic pigment, further function as the effect of fixation.
It is further preferred that the mass ratio of the chopped fiber A, dye solution, tryptophan and color fixing agent described in step (4) are 1：10-
20：0.03-0.05：0.05-0.08.
Preferably, the artificial leather material described in step (5) is polyurethane or polyvinyl chloride.
Preferably, the brushing amount of the acrylic acid adhesive described in step (5) is 20-30g/m2Artificial leather.
Beneficial effects of the present invention are：
1st, the present invention makees raw material using animal fur leftover bits, produces dermis flocked pile fiber, turns waste into wealth, more fine than common flocking
More soft, the fine and smooth feel of dimension.
2nd, the made dermis flocked pile artificial leather of the present invention can meet the multiple demand of consumer and the design need of personalization
Ask, low compared to fur coat cost, source is more extensive, and clothing difficulty is low, is adapted to industrialized production.
3rd, compound base extraction animal fur particle is formed using a variety of weak base compounding, so that animal's leather decomposes,
So that fur quick separating, while animal wool is not caused to damage again, influence the quality of leather flocking short fiber.
4th, the leather flocking short fiber bright prepared by the present invention, even dyeing, dyeing firmness are high.
