Embodiment 2
The manufacture method of moisture absorption superfiber leather, comprises the following steps:
A. dye layer 1 is dyeed;
Dyeing is entered water and is in charge of at normal temperatures using the O-shaped low tension type dyeing machine of Italy Ba Zuoni environmental protection, staining machine Enter cloth, and add CD-1000N, which is stirred and issued automatic feeding system in staining machine pair cylinder, which is pumped into dyeing automatically In machine, the pH value in staining machine is controlled between 3 and 6;Then technological parameter is input in computer system:Tension force 20N, rotating speed 150m/min, nozzle exit pressure 0.21MP/cm2, main pump rotating speed 1005r/min, bath raio 1:5,98 DEG C of pre-treatment temperature, programming rate For 2 DEG C/min, temperature retention time 20min;Room temperature is cooled to the speed of 1.5 DEG C/min afterwards, is washed 2 times, and is added CD-1000N; 50 DEG C of post-processing temperature, temperature retention time 20min are being warming up to the speed of 2 DEG C/min.In computer system input process above ginseng Number, computer automatically form technology establishment.Computer is set as automatically, whole process operation be automatically brought into operation after the completion of by go out cloth.
Wherein, when dye layer 1 carries out moisture absorbable and breathable finishing using CD-1000N after dyeing, pH value is controlled between 3 and 6. Temperature control during arrangement is most important, slow during intensification(2℃/min)Control lower temperature is reacted, in case The unstable precipitation of CD-1000N.
B. dewatering process is carried out after washing;
It is dehydrated using centrifuge, is dehydrated parameter:Rotating speed 500r/min, working time 5min.
C. carry out silicone oil to dye layer 1 after being dehydrated to wash;
Silicone oil adds hydrophilic softener during washing, and its consumption compares 0.5%-1.5% for weight.In the present embodiment, The consumption of hydrophilic softener compares 1% for weight.
D. dried after silicone oil is washed, drying time is 2h-4h, and drying temperature is 110 DEG C -130 DEG C;In the present embodiment In, drying time is 3h, and drying temperature is 120 DEG C;
E. heat treatment is carried out to dye layer 1 after drying;
Setting process is to be managed using Korea and heat setting machine, technological parameter:Frame amplitude 155cm, 160 DEG C of temperature, machine speed 30r/min, nip pressure 2.5t, overfeeding 28, cabinet air quantity:Windward 500r/min, leeward 800r/min;Operation:Entering cloth Roll is turned down pressure and dips 1 surface of dye layer for 2.5t;160 DEG C of setting control computer box temperature;Adjustment overfeeding 28;Dye layer 1 passes through forming machine with the cloth machine speed that enters of 30m/min, goes out cloth measurement cloth fabric width 155cm.
Using CD-1000N as nanometer finishing agent, and by controlling nano finishing technical matters main points, and in silicone oil Middle addition hydrophilic softener is washed, soft warm property, moisture absorbing and sweat releasing and the frivolous heat-preserving function of superfiber leather is enhanced, which is fixed Ability is higher.
F. the method in 1 lower surface roll marks of dye layer coats one layer of drying agent solution, then is dried, and forms water repellent layer 10;
Due to there is water repellent layer 10, the surface tension of 1 lower surface of dye layer is which reduced, checked capillary effect and pressure differential Formation, make shipwreck to enter from 1 lower surface of dye layer so that the exchange of the water in the follow-up solvent when composite membrane 2 is coated Only carry out in 1 upper surface of dye layer, it is to avoid the generation of blister, it is ensured that the quality of composite membrane 2, and the setting of water repellent layer 10 So that dye layer 1 has certain moisture protection.
G. the making of composite membrane 2:
1)On dye layer 1 by politef adhesive coated after being shaped, part politef adhesive Penetrate into groove 5 and be full of groove 5, politef adhesive forms polytetrafluoroethylene film in 1 upper surface of dye layer;
Politef adhesive adopts normal temperature cure, that is, after being coated in dye layer 1, be placed at a temperature of 15 DEG C -32 DEG C 10h, or 5h or 24h, it would however also be possible to employ the mode of drying is carried out.After the solidification of politef adhesive, in groove 5 Politef with 1 surface of dye layer politef be integral type structure, so as to polytetrafluoroethylene film is arranged It is on dye layer 1, difficult for drop-off.
2)By the polyurethane of solid-state and dimethyl formamide solution mixed dissolution, the solid content of solution is between 18%-20%; In the present embodiment, by polyurethane formulations into the polyurethane adhesive that solid content is 18%, it is also possible to which it is 20% to make solid content Polyurethane adhesive makes the polyurethane adhesive that solid content is 19%.
Dimethyl formamide solution is the primary solvent for dissolving polyurethane, can add secondary solvent, secondary solvent be acetone, The mass ratio of the secondary solvent that butanone, ethyl acetate, toluene are mixed to form, primary solvent and secondary solvent is 3:2.
Polyurethane is real in dimethyl formamide solution to be dissolved, and polyurethane chain is in curly wherein, and interchain can Can mutually wind, there is the dynamic balancing of " winding and unwrapping " state, with the reduction of concentration, the winding of interchain is progressively opened; It is clearly as the winding of interchain, exacerbates the viscosity of solution, unfavorable to film, thus from solution solid content in 18%-20% Between.
3)Using dry fabrication composite membrane 2:The polyurethane adhesive scraper got ready is applied directly to into politef On thin film;
4)Composite membrane 2 is placed in baking oven to evaporate the solvent on adhesive for polyurethane;
Concrete mode is as follows:First heated up with the programming rate of 2 DEG C/min, evaporated some impurity solvents, heated up To secondary solvent boiling point when be persistently incubated baking 10min, continue to heat up with the programming rate of 2 DEG C/min, finally continue at 150 DEG C 30min is dried in insulation.
H. the preparation of basic unit 3:Basic unit 3 is formed by weaving using spandex yarn, and spandex yarn forms some coils 6 in lower surface, and two More than individual, continuous coil 6 forms a salient point 7;
I. the mixing liquid of antistatic oil preparation is sprayed in basic unit 3 by spray pattern, balances 24h, it is also possible to balance 12h or 36h;
J. dye layer 1 is fitted in into 3 upper surface of basic unit by the way of wet method laminating;
Concrete operations are as follows:1 lower surface of dye layer sprays one layer of tack coat 8, and 1 lower surface of dye layer is fitted with tack coat 8, 3 upper surface of basic unit is fitted with tack coat 8, and during laminating, temperature is 150 DEG C -170 DEG C, forms gapless laminating, and with 5m/min's Speed run, adopt low-pressure and dye layer 1 and basic unit 3 dipped for 2.5t, after respectively through 105 DEG C -110 DEG C, 110 DEG C -115 DEG C, 115 DEG C -120 DEG C, 120 DEG C -125 DEG C, 125 DEG C -130 DEG C, 130 DEG C -135 DEG C, 135 DEG C -140 DEG C of temperature section carry out by Step drying, the holdup time in each stage is 5min.
Tack coat 8 is mainly made up of primary raw material of vinylacetate, acrylate, ethylene etc., using EVA application formula Form, with binding speed it is fast, original viscosity is good, bonding force is strong, film formation at low temp performance is good.
K. it is placed in room temperature after drying to be conserved, curing time is at least 24h;
