Description
Technical field
The present invention relates to the dyeing field, particularly a kind of polyamide (Nylon, Polyamide; Abbreviate PA as; Comprise nylon 4, nylon 6, nylon 46, nylon 66, nylon 7, nylon 8, nylon 9, NYLON610, nylon 1010, nylon 11, nylon 12, nylon 13, nylon 612, nylon 9 T, nylon 13; MC nylon; Nylon MXD 6 nylon and all polyamide derivatives) with the engrain technology of polyolefin polyolefin (Polyolefin comprises ethylene copolymer, propylene copolymer and related derivatives thereof), this engrain technology utilization one compatilizer precursor and an amido, hydroxyl or epoxy radicals chemicals are directed against this polyamide and polyolefin carries out upgrading; This polyamide and polyolefin behind upgrading; Have the low temperature stainability, utilize a chemically-reactive dyes and/or ACID DYES to dye at last, can make that polyamide and the polyamide fiber after the dyeing has good dyefastness, fastness to light, wear-resisting rubbing fastness, washing fastness.
Background technology
Be commonly referred to as the polyamide (Polyamide of nylon (or anti-grand (Nylon)); Abbreviate PA as); Be that (linear condensation polymer always that major key CONH-) repeats to constitute has high crystalline, chemical-resistant resistance, oil-proof composition, anti-solvent, abrasion resistance is good, coefficient of friction is little, be difficult for thermal cracking, the range of work wide and characteristic such as self lubricity by the monamide base; In addition, nylon has the TENSILE STRENGTH height on engineering properties, resistance to impact is high and advantages such as good elasticity, toughness and ductility, so be widely used on the various composites such as weaving industry, industrial fibre and fibrous reinforcement.
The architectural feature of nylon (Nylon) is that the end of its strand has a carboxyl and (COOH) (NH2) waits the functional group with dyeability with an amido; The molecule middle-of-chain have a large amount of hydrocarbon chains (CH2) with the monamide base (NHCO-); So many dyestuffs: for example an alkali property dyestuff, an acid mordant dyes, the acid dyestuff of the wrong salt of a metal, a direct dyestuff, disperse dyes, an azo dyes, a vat dyestuffs and an ACID DYES etc. can both dye to it; And the dying property of fiber depends on a dispersal behavior of dyestuff and affinity (affinity) and combination between fiber-dyestuff; In these above-mentioned dyestuffs; Only there is this ACID DYES to contain monosulfonic acid sodium root (hydrophilic radical SO3Na); Can (NH2) combines, and then have a dying property and a fresh colour preferably, remaining these dyestuff all passes through a hydrogen bond (hydrogenbond) or a Fan Dewaerli (Van der Waals forces) combines with nylon fiber through this amido in ionic bond knot (ionicbond) or an electrostatic force (electrostatic force) and the nylon fiber; Only can catch more shallow color; Therefore on considering with regard to each side such as equalizations, this ACID DYES is current first-selection to nylon fiber dyeing, on related application, is the most general, use amount also maximum.
The polyamide fiber dyeing of prior art, referring to Fig. 2, step 21: polyamide fiber is carried out upgrading, step 22 through a upgrading technology: dye with this ACID DYES again; Wherein existing modifying process to polyamide has: add the chain regulator of a variety classes and addition, (content NH2) imports the functional group of a special construction simultaneously with this amido of increase nylon molecule chain end; Or in dyeing course, add a dye leveller or other auxiliary agent, simultaneously with a ultrasonic treatment, at last through after the redox system dyeing; Carry out fixation treatment or utilize water to make this amide groups that (its induction period is shortened in NHCO-) ring-opening polymerization, improves reaction rate as a ring opening agent; When reaching new balance; Because of polymer molecule increase wherein, (content NH2) also increases this amido thereupon, or suitably improves this amide groups (NHCO-) temperature of phase before and after the hydrolytic polymerization; To increase this terminal amido (content NH2), and then reach the purpose of upgrading.
Yet; Because polyamide (nylon; Nylon) this amido of molecule chain end (content NH2) extremely low (be merely wool about 5～10%); Through above-mentioned modifying process still can't significantly promote this amido (content NH2) promptly can't obviously improve the Color of nylon, comprehensive above-mentionedly learns that existing nylon fiber dyeing has disadvantage:
One, only can obtain the Color of moderate depth: because this acid dyeing and polyamide are to be combined by this ionic bond knot or this electrostatic attraction since key tie (bonding) a little less than, so only can obtain the Color of moderate depth.
Two, dyefastness, fastness to light and washing fastness are all not good: through the nylon of existing polyamide fiber dyeing dyeing; Very easily washed, solar radiation or be exposed to the influence of special gas moderate environment factor, thereby take place a dyestuff fade or be infected with phenomenon, have dyefastness, fastness to light and all not good shortcoming of washing fastness.
Three, dyeing quality is uneven, cost is high: the engrain technology of existing polyamide fiber is easily because of factors such as the selection of dyeing condition and this auxiliary agent are improper; Cause aberration, heterochromatic, dye phenomenon such as class, the dyeing process of the dyeing of this existing nylon fiber is numerous and diverse simultaneously, the fixation treatment cost high.
Four, dyeing temperature is high: the dyeing temperature of existing polyene amine fiber must be more than 100～120 ℃, cause with high costs, expend effective energy.
This shows that existing polyamide fiber dyeing has many shortcomings, thereby haves much room for improvement.
In addition, polyolefin (polyolefin is like polyethylene, polypropylene) light weight; Abundant raw material, characteristic that have that technology is simple and easy, light specific gravity, water imbibition is low and endurance, static electricity resistance, the excellent function of soil resistance, high comprehensive performance; Production cost is lower, so of many uses.
Because polyolefinic nonpolar structure, it has been generally acknowledged that to dye is its maximum shortcoming because the fiber itself hydrophilicity is extremely low, so and the affinity between the dye well chemical assistant not good, use traditional dyeing and stamp mode, all can't reach painted effect.Polyamide fiber colorize method major part adds organic or inorganic pigment when spinning at present, makes its colouring; This kind mode is simple, with low cost and can obtain better fastness, yet this method also has its inevitable shortcoming; Only be fit to a large amount of manufacture order one colour systems, on chromatogram, do not catch up with the requirement of consumption market and renewal, other shortcoming as: can't stamp, stock etc.; Therefore, be main with carpet product and a small amount of popular clothing product colourless or that demand is bigger in the use, how general dyeing and finishing technique; Be applied to polyamide fiber, making it to become welcome new material is the problem that consider is arranged.Therefore; Can improve polyolefin dyeing usefulness through following method: hypochlorous sodium chlorination and photochemical bromination are handled the upgrading polypropylene fibre and are come and cationic dyeing; Polypropylene fibre that upgrading is crossed and dyestuff produce covalent force, bleaching, washable, fastness to sea water lifting, and the fiber regain improves; But intensity descends, and need do post processing and just can improve its fastness to light; Perhaps use the compound of series of acrylate, produce the co-polymer that is fit to alkali property dyestuff, ACID DYES and disperse dyes dyeing with radiation exposure combined polymerization polypropylene; But also can on polypropylene, increase the additive of some polarity and be spun into the fiber of acid dyeing; Even can use hydrogenated oligocyclopentadiene or with wool to the polypropylene blending and its result is discussed.These methods can increase polyacrylic colouring power, yet, but cause the sensitiveness of polypropylene to light, the reduction of engineering properties, and the most important thing is that the required expensive polypropylene that makes of upgrading is unfavorable for commercial use.Disperse dyes and hydrophobic fibre are in supercritical carbon dioxide, and intermolecular favorable compatibility makes it be fit to dyeing and without any need for auxiliary agent.Thus through desirable PET (polyethylene terephthalate, PETG) staining technique and then the diffusion of research disperse dyes in fiber and the dissolving situation in overcritical.The diffusion of dyestuff and solubility then are to decide according to the character of dyestuff itself.In addition, also have with disperse dyes and under supercritical CO 2, dye polyamide fiber, the dyestuff that uses is the decentralized azo dyes, and how it contain ring structure, so the general disperse dyes of its color are dark.Except cost high, can't commercialization outside, and azo dyes do not encouraged to use in the current new century of advocating environmental protection, especially in advanced person's country disabled (like European Union), comprehensive above-mentionedly gets existing polyamide fiber dyeing and has following shortcoming:
One, only can obtain the Color of moderate depth: because existing upgrading polyolefin is mostly through disperse dyes dyeing; It is to dye through the attraction between this secondary or physical bond (like hydrogen bond or Fan Dewaerli); Since key knot (bonding) a little less than, so only can obtain the Color of moderate depth.
Two, dyefastness, fastness to light and washing fastness are all not good: through the polyamide fiber of existing dyeing dyeing; Very easily washed, solar radiation or be exposed to the influence of special gas moderate environment factor, and take place a dyestuff fade or be infected with phenomenon, have dyefastness, fastness to light, washing fastness and all not good shortcoming of friction fastness.
Three, dyeing quality is uneven, cost is high: the dyeing of existing polyamide fiber is easily because of factors such as the selection of dyeing condition and this auxiliary agent are improper; Cause aberration, heterochromatic, dye phenomenon such as class, the dyeing process of existing polyolefinic dyeing is numerous and diverse simultaneously, the fixation treatment cost high.
Four, dyeing temperature is high: the dyeing temperature of existing polyamide fiber must be more than 90～120 ℃, cause with high costs, expend effective energy.
Five, not environmental protection: azo dyes with contain heavy-metal stain in the current new generation of advocating environmental protection, do not encouraged to use, especially disabled in advanced person's country (like European Union).
This shows that existing polyamide fiber dyeing still has many shortcomings, thereby haves much room for improvement.
