As shown in Figure 2, the technological process of terylene nonwoven carpet is as follows:

By conventional white polyester staple fiber (basic specification is fineness 4-15dtex, length 51-75mm) feeding mixing willow is carried out preliminary shredding and hair, the terylene short fiber of different fineness and length is tentatively mixed; By 1 grade of shredding and the shredding of 2 grades of shredding two-stage openers, and spray antistatic additive simultaneously, make fiber block, coma disassociation absent-mindedness, the fibrous raw material of different size obtains to mix uniformly; By cotton storage tank fibrous raw material is further mixed; By the mixed fibroplastic fibrage of shredding is supplied with carding machine, make fibrous raw material obtain shredding more fully and evenly mixing, mixed and disorderly mutually cohesion between the fiber simultaneously, formation has the fibre web of certain cohesive force, and the grammes per square metre of fibre web is then carried out Comprehensive Control by the speed of regulating cotton storage tank and carding machine; By the lapping machine fibre web that carding machine is exported is moved back and forth, with orderly interleaved mode laying, regulate in conjunction with the speed of output end curtain simultaneously, the control fibre web laying number of plies is to reach the design surface density of product; By pre-needling machine fibre web is carried out acupuncture, make entanglement obvolvent mutually between the fiber, fibre web obtains reinforcing, and skid resistance becomes big between fiber, forms the pre-needling grey cloth with certain ultimate strength; By the acupuncture fluffing machine pre-needling grey cloth is carried out high speed, the napping of highly dense acupuncture single face, thereby make the needle punched blanket of matte; Then needle punched blanket is carried out every check, after the assay was approved, then carry out rolling, finally obtain terylene nonwoven carpet grey cloth by up-coiler.

As shown in Figure 3, terylene nonwoven carpet printing technology flow process is as follows:

Terylene nonwoven carpet grey cloth is placed on the debatching device, and grey cloth obtains certain tension force through each roller of storage cloth holder traction back, and it is neat and well spaced that cloth cover is straight, can draw to the driving-belt of ink-jet decorating machine grey cloth is parallel at this moment; Meanwhile, carrying out soft water by ion exchange column handles, make soft water and thickener, dyestuff acquisition high speed dispersion mix or can directly disperse to mix with emulsification pump, the evenly black slurry of final formation be evacuated in 16 black bottles the China ink slurry stand-by with membrane pump afterwards again; According to the corresponding China ink bottle of the color that is drawn a design color, regulate the computer sprayed printed system then, so that blanket grey cloth is carried out spray printing, then by regulating the control of air pressure size, the even spray printing of China ink slurry is on grey cloth for ink ejection amount and jet speed; By tentering formula forming machine, the parallel traction of grey cloth behind the spray printing is entered baking oven (180-200 ℃ of maximum temperature scope, length 48m), in baking oven, dry, color development and fixation process, the baking oven exit has cooling blower that grey cloth is carried out cooling processing, carries out dry cleansing simultaneously; Afterwards the stamp grey cloth is drawn to and puts cloth holder and cool off, and make cloth cover smooth by the roller drawing tension; At last the stamp grey cloth is carried out every check, carry out rolling by up-coiler subsequently, can pack product behind the harvest volume and handle or enter the processing of next process gluing.

(1) foundation of dye selection:

1. the material of carpet is used terylene short fiber, and is cheap, and buying is convenient;

2. the purposes of carpet, carpet purposes difference requires emphasis also different to the color fastness of dyestuff;

3. whether the color category of dyestuff is complete;

Whether 4. dye fixing speed, degree of fixation height and compatibility value be close need consider that all generally the painted disperse dyes of selecting for use of terylene are advisable.

(2) selection of thickener

Thickener is meant the macromolecular compound that plays thickening power in mill base, before adding mill base, generally it should be dispersed in the water, makes to have colloidal solution certain density, stiff.It is big many that the viscosity of its ratio of viscosities mill base is wanted.

Thickener mainly contains following effect:

1. mill base is carried out thickening;

2. the powder component of checking colors carries out the effect of decentralized medium and dilution;

3. the carrier between dyestuff and the auxiliary agent;

4. promote colouring and fixation.

Thickener is required to have: must overcome because the imbibition phenomenon that the capillary effect of pile causes guarantees the decorative pattern clear-cut, and this just requires print paste must have certain fluidity, the while does not produce imbibition again; Thickener also should have wetability, hygroscopicity and embrace water-based, and its concentration keeps stable after long storage time.

The principle that thickener is selected is as follows:

1. should choose suitable dye type earlier, and then select corresponding thickener according to different carpet fiber materials according to the characteristic of fiber and selected dyestuff;

2. should choose the high-purity synthetic thickening agent or, guarantee that simultaneously nozzle is unobstructed through the sex change natural paste that process of refinement is crossed;

3. thickener should have easy dispersion, the easily characteristic of one-tenth paste, and one-tenth is stuck with paste back viscosity maintenance and stablized;

4. guarantee the thixotropic property of thickener, can satisfy the infiltration and the fineness requirement of carpet stamp simultaneously;

5. easy cleaning.

(3) preparation of standby slurry

The general used thickener of digital code spray-jet carpet knitter is the high-purity synthetic thickening agent, generally all needs thickener is mixed with former paste before the preparation mill base, as standby slurry.That is to say that promptly add magma when stirring demineralized water, fully stirring makes it to mix then, thereby be mixed with magma, use during in order to the preparation mill base than high viscosity.Leave standstill a period of time afterwards, so that the abundant swelling of thickener, guarantee the stability of preparation mill base viscosity.

The detailed process of standby slurry preparation: promptly add thickener in the time of agitating deionized water, it is even until slurry to continue stirring afterwards, and general the stirring needs 15-30min consuming time (the concrete time decides according to the performance of variety classes thickener); After stirring, leave standstill a period of time, so that thickener can be fully expanded.

What below introduce is by the prepared standby slurry viscosity of thickener in several:

160 * trme deposit slurry concentration 10g/l, the viscosity after the complete swelling is about 12000cps.

The concentration of 160conc deposit slurry is 16g/l, and the viscosity after the complete swelling is 5000-6000cps.

The concentration of 5352 deposit slurries is 30g/l, and the viscosity after the complete swelling is about 3000cps.

The concentration of CT-DP deposit slurry is 16g/l, and the viscosity after the complete swelling is 5000-6000cps.

The concentration of Texipo167-5055 deposit slurry is 10g/l, and the viscosity after the complete swelling is 3000cps.

(4) composition of mill base and preparation

1. the part of mill base and effect thereof

Mill base generally is made up of auxiliary agents such as thickener, dyestuff, bleeding agent, defoamer and anti-cremes, and the effect of main component is as follows.

A, bleeding agent:

Concentrator is permeated to the root direction along knitting wool, prevent slurry, generally select for use low bubble bleeding agent to be advisable in the imbibition of blanket face;

B, defoamer:

For preventing that effectively the auxiliary agent in the concentrator from causing the spray printing difficulty in the stage of sizing mixing because of producing a large amount of foams, can suitably add defoamer.Generally select the unabiding non-silicon defoamer of suds suppressing properties for use, in order to avoid the effect of the anti-creme of influence.

C, anti-creme:

When the wetting carpet surface fiber effects of concentrator not good, or carpet is when entering the higher relatively steam box of humiture, because humiture difference makes steam in the carpet surface condensation, thereby cause dyestuff to ooze out, cause carpet surface " bloom " to occur from fiber surface.Anti-creme helps fiber wetting, can just form the little foam of thickness in decatize aspire to carpet surface, can prevent effectively that the dyestuff water that is condensed from taking out of, thereby reach the purpose of eliminating bloom.

2. the process for preparation of mill base

A, prior to adding the standby slurry of desired concn in the fixed container;

B, continuation afterwards add deionized water and other required auxiliary agents (as defoamer, bleeding agent etc.) (note: chemical reagent all need dilute before adding), stir;

C, at last dyestuff is fully dissolved, join after the filtration in the slurry (note: dyestuff must filter because dyestuff contains impurity, some in addition can stop up shower nozzle);

D, wait to be stirred to evenly after, can tested viscosity, and be adjusted to suitable viscosity number according to actual needs.

(5) influence the factor of color coloured light:

The factor that influences color coloured light mainly comprises: dyestuff, carpet material, carpet background color, drying condition (being mainly time and temperature), mill base viscosity and pH value etc.;

1. dyestuff, when adding dyestuff, the dyestuff of Tian Jiaing each time, its purity and coloured light must be consistent respectively;

2. carpet material, unlike material carpet use the color coloured light with gained behind a kind of dyestuff spray printing to have certain otherness;

3. carpet background color, the carpet background color is pure white, but the overall color that other color is presented behind spray printing carpet all has influence in various degree;

4. drying condition needs suitably, and the length of time and the height of temperature all can exert an influence to the dyestuff color development;

5. mill base viscosity, general mill base viscosity is big, and then color is full;

6. pH value 〉=7

(6) every technic index is to the influence of spray printing effect

The spray printing effect of carpet is mainly considered from the following aspects: three aspects such as the saturation degree of color, permeance property and the 3rd look.

The concentration of saturation degree and dyestuff, colorant match etc. are relevant; Permeability comprise dying material to the infiltration of carpet root direction and dying material to two aspects of infiltration of blanket face direction, it is relevant with bleeding agent, the moisture pick-up properties of blanket own etc.; The 3rd look relevant with color, viscosity, amount of thickener, pattern etc.

1. the factor that influences carpet spray printing effect mainly contains the following aspects:

The arranging density of a, carpet pile, height of naps and fluffy degree thereof;

B, mill base viscosity;

The characteristic and the consumption of c, thickener and dying auxiliary agent;

D, spray printing pressure;

E, spray printing height;

F, spray printing speed;

G, decatize technology.

2. the adjusting of viscosity:

The principal element that influences viscosity has: the height of the self performance of carpet printing machine, the thickness of carpet, carpet pile, the fluffy degree of carpet pile and the arranging density of carpet pile etc.

The self performance of a, carpet printing machine requires viscosity to remain between the 60-500cp, is preferably in below the 450cp;

The thickness of b, carpet, the thickness difference, the requirement of the slurry viscosity of checking colors is also different.The general desired mill base viscosity of thin carpet is higher than thick type carpet;

The height of c, carpet pile, height of naps are high more, and the infiltration of dying material is difficult more, so the mill base of high required the dying material of carpet of fine hair should suitably hang down;

The fluffy degree of d, carpet pile, fluffy degree is good, and then dying material easily permeates; Otherwise, then infiltration difficulty, this moment, its mill base viscosity can suitably reduce;

The arranging density of e, carpet pile, the fine hair arranging density is big, and then the infiltration of dying material is difficult, and this moment, its mill base viscosity can suitably reduce;

Whether take all factors into consideration the scope that can determine mill base viscosity after above each factor, can use little model machine to draw a design and the vapour baking under the reality, it is suitable to evaluate the viscosity of initial judgement by the effect of final products then.

3. influence the factor of infiltration:

The factor of influence infiltration mainly comprises: the arranging density of carpet pile, height of naps, mill base viscosity, bleeding agent consumption, spray printing pressure, spray printing speed, China ink amount.

A, fine hair arranging density are big, dying material infiltration difficulty then, and can suitably increase the bleeding agent consumption this moment;

B, height of naps, highly bigger, then dying material infiltration difficulty can suitably increase the bleeding agent consumption at this moment;

C, mill base viscosity, in general, the dying material that mill base viscosity is low more easily permeates;

D, bleeding agent consumption are big, and then dying material permeance property is better, if but the consumption of bleeding agent is excessive, and then can make dying material spread to all directions infiltration, thus influence flower type, so should grasp the limit of bleeding agent consumption;

E, if its permeance property is not still improved after increasing the bleeding agent consumption, then may be since black quantity not sufficient to cause participating in the amount of dye of carpet fiber reaction limited, need to increase China ink this moment and measure;

F, spray printing pressure, spray printing pressure help the infiltration of dying material greatly;

G, spray printing speed are less, and the China ink amount increases, and then the infiltration of dying material is difficult;

H, China ink amount, the China ink amount is big, then dying material infiltration difficulty;

Estimate bleeding agent consumption size and need take all factors into consideration above each factor, can at first use little model machine specifically to test to determine the size of the concrete consumption of bleeding agent.

4. the China ink amount is definite:

The China ink amount of general carpet stamp is the 300%-400% of carpet grammes per square metre, promptly is 3-4 times of carpet grammes per square metre.Grammes per square metre is meant the weight (weight that mainly refers to carpet pile) of every square metre of carpet.

In general, dying material is permeable to the carpet pile root or only carries out part infiltration or only need that the carpet top layer is painted get final product, the concrete condition difference, and China ink amount size is difference also.

5. change the approach of China ink amount: spray printing pressure, spray printing speed, nozzle bore, slurry China ink viscosity.

A, spray printing pressure, each print cartridge are equipped with the corresponding button with regulation and control force value size separately, and the pressure of different colours dyestuff can there are differences, and specifically decides (generally determining by little prototype experiment) on actual conditions;

B, spray printing speed, spray printing speed is to the influence of China ink amount big (spray printing pressure is little to the influence of China ink amount than spray printing speed to the influence of China ink amount);

C, nozzle bore, if change spray printing pressure and spray printing speed still can satisfy the requirement of China ink amount inadequately, this moment can be by changing the nozzle bore size to change black amount.

D, starch black viscosity, starching the big I of black viscosity directly influences the China ink amount, and viscosity is big, and then whitewashing amount is little; Otherwise then whitewashing amount is big.

(7) other points for attention

1. hardness of water must be less than 72ppm, and the hardness of soft water that use every day is consistent.

2. dyestuff must can be added in the mill base after filtering.

3. accelerant ACE must be added in the water and dilute, and must guard against in the white slurry of direct adding.

4. light slurry series, slurry amount and amount of dye are few, and fixation is very fast relatively, and before diluted the moving down of surface slurry, dyestuff fixation finishes; For the dark colour mill base, if use different thickener consumption preparations with a kind of dark colour mill base, and guarantee that its viscosity also can be adjusted to unanimity, final result shows, use the few formulated mill base of thickener consumption, when vapour dries by the fire, the easily diluted downward infiltration of surperficial slurry, and, thereby cause the color of fine hair tip to shoal (mainly being) because do not have due to enough thickener constraint dyestuffs easily to the peripheral direction diffusion; The mill base that uses thickener consumption polygamy system to form then the problems referred to above can not occur, mainly is because of the amount of slurry abundance, so when vapour dried by the fire, mill base flowed slow relatively, and mill base is direction infiltration at the bottom of blanket.

5. determining of color development time generally is lower than 10min, and temperature must keep uniformity in the baking oven.

6. for reducing error, the physical condition when every experiment condition of little model machine must maximizedly be produced with big machine is consistent.

7. during spray printing, follow spray printing principle from shallow to deep,, then the dying material of two kinds of colors is contained in respectively in two print cartridges far away of being separated by and is advisable if two kinds of color positions in pattern are more close.

As shown in Figure 4, terylene nonwoven carpet typing coating technique flow process is as follows:

Grey cloth after the spray printing pattern has finished possesses certain force of strain and intensity, can require to carry out gluing according to difference thus, is coated with flexible glue or ebonite.At first grey cloth is drawn to impregnator by the debatching device, and blanket faces down, blanket back glue.Secondly join glue and finish by mixer, the glue for preparing is evacuated to two of impregnators by foaming machine can be passed through to regulate two roller spacings, adjust foaming density and speed of production above the pressure roller this moment, and then the control spread.Enter baking oven by the parallel traction of grey cloth of tentering formula forming machine after then with gluing, in baking oven with drying adhesive.Again grey cloth is carried out every check, draw, cool off by the storage cloth holder at last, make the smooth rolling of grey cloth, be terylene nonwoven stamp product.
