Abstract

A skin-imitated microfiber fabric belongs to the technical field of top grade clothing fabric and is formed in the way that acrylon superfine short fiber is processed by two carding machines and a lapping machine to form two-layer webs, knitted fabric taking polyester filament yarns or pure spun polyesters as raw materials is laid on one-layer web, then the other-layer web is laid on the knitted fabric so as to obtain Single-Layer Sandwich Base Cloth; the Single-Layer Sandwich Base Cloth is subjected to preneedling and high-pressure spunlace to obtain Double-Layer Sandwich Base Cloth; the Double-Layer Sandwich Base Cloth is subjected to special bonding, presetting, dyeing, setting, drying, singeing and ironing so as to obtain the skin-imitated microfiber fabric; and the total fineness of polyester filament yarns is 50 D to 100 D, the total fineness of pure spun polyesters is 30 S to 90 S, and the fineness of the acrylon superfine short fiber is 0.6 to 3.0 D. The skin-imitated microfiber fabric has shining color and luster, good handle, elasticity and draping, and tearing strength of more than 70 N, can be cleaned for use repeatedly, and omits the step of impregnating DMF (Dimethyl Formamide) polyurethane, so that Skin Feel is realized, and a novel solvent-free high-density superfine fabric is provided.

Description

The super fine fabric of a kind of artificial leather
Technical field
The invention belongs to field of nonwoven fabric technology, being specifically related to one does not need the impregnation of DMF polyurethane can realize the super fine fabric of artificial leather of " skin sense ".
Background technology
Non-woven fabrics does not need the fabric formed of spinning cotton and weaving cloth, needle punched non-woven fabrics textile staple or long filament is carried out orientation or supports row at random, forms fibre net structure, then adopts machinery, the method such as hot sticky or chemical reinforces, technological process is short, but has the defect yielded poorly.Spunlace non-woven cloth is that the fibre web through being shaped sends into spun-laced machine reinforcing, and be first pre-humidifying process, the fibre web through prewetting enters water spine area, and the hole for water spraying of water jet water spray plate ejects the fine water jet of multiply that pressure is 60bar-250bar, and vertical sand shooting is to fibre web.Water jet makes a part of surface fibre in fibre web be subjected to displacement, and comprises moving both vertically to fibre web reverse side, after water jet penetrates fibre web, is subject to the rebound effect of holding in the palm lace curtaining or rotary drum, scatters to the reverse side of fibre web with different orientation.Water jet directly impact and the current that rebound double action under, the fiber in fibre web is subjected to displacement, intert, tangle, obvolvent, forms numerous flexible entanglement point, thus fibre web is reinforced.Super fine water thorn nonwoven fabric is to make wet tissue, sanitary napkin, face paper in the market, and range of application is narrower, and stretch-proof brute force is low, and service life is short, mostly is single use.And super fine acupuncture short fiber PET non-weaving cloth, general thickness is all at more than 0.5mm, and feel is comparatively hard, and sense of hanging down is poor, and elasticity is not enough, and color fastness is lower, need, with the toxic solvent environmental pollutions such as DMF are serious and water consumption is higher, fail to be applied to high-grade dress ornament field.
Therefore, need that a kind of cost is low, without the need to using solvent, the superfine fibre nonwoven cloth of non-environmental-pollution comes alternative existing spun laced fabric (film) and acupuncture sea-island fibre cloth.
Summary of the invention
The feel that the present invention solves existing super fine acupuncture nonwoven fabric and water thorn nonwoven fabric is harder, sense of hanging down is poor, elasticity and comfortableness poor, color is single, color fastness is lower, and be only the defect of single use, wearability difference, provide a kind of existing corium feel to have again the super fine fabric of the artificial leather of higher wearability.
For above essential technique problem, the present invention adopts following technical scheme to solve:
The super fine fabric of a kind of artificial leather, is characterized in that adopting following preparation method to obtain:
(1) nonwoven web makes, and with the ultra-fine short fiber of acrylic fibers for raw material, obtain nonwoven web through combing, lapping, the ultra-fine short fiber of acrylic fibers accounts for 100%, and the fiber number of the ultra-fine short fiber of acrylic fibers is 0.6 D-3.0D, and length is 38-51mm, and nonwoven web has 0.2-0.5g/cm 2density and the thickness of 0.6-1.9mm;
(2) knitting base cloth makes, and with polyester filament or pure yarn of washing for raw material, obtain Ji Bu through knitting, described polyester filament total fiber number is 50D-100D, and pure yarn total fiber number of washing is 30S-90S;
(3) step of base cloth is sandwiched in the middle of two-layer nonwoven web: in two-layer nonwoven web, sandwich step (2) gained pin ply ground fabric, stung in advance by needing machine and obtain compound embryo cloth, compound embryo cloth again under 2-8 road hydraulic pressure is the repeated action of the type high pressure jet head of 60-250 handkerchief by fibre matting reinforced composite, dry at 100 DEG C ~ 160 DEG C temperature;
(4) pre-setting step: composite grey fabric crosses clear water, oven temperature: low-temperature space 90 DEG C, 130 DEG C, high-temperature region, speed of a motor vehicle 35-45 m/min, overfeeding is 0, door 165 centimetres-175 centimetres;
(5) staining procedure: cationic dyeing, dyestuff before entering cylinder with 1:15 bath raio electric stirring 10 minutes, add 0.5-1 grams per liter glacial acetic acid, during first dyeing from normal temperature, heating rate controls at 0.5 DEG C/min, and 50 DEG C are entered cloth, pretreating reagent 2-3g/L is added in dye bath, be warming up to 80 DEG C of process 20min, discharge opeing, 50 DEG C of water are cleaned; Water inlet, is warming up to 50 DEG C and adds the dye of positive ion, add cationic levelling agent and wetting softener before being warming up to 60 DEG C, be warming up to 120 DEG C, if cooling, discharge opeing after contaminating light 40min; If lower the temperature after contaminating dark 60min, discharge opeing, adding water, it is clean to be washed at 50 DEG C, goes out cloth;
(6) shaping and drying: cross and add 4% softening agent and water, temperature is 170-180 DEG C, and the speed of a motor vehicle is 15-20 m/min, and overfeeding is 5%-10%;
(7) singe: adopt continous way gassing frame, the speed of a motor vehicle is 50-70 m/min and processes;
(8) hot light: adopt continous way natural lustre finishing machine, the speed of a motor vehicle is 25-35 m/min and processes;
(9) inspection, clot.
Further, described polyester filament is polyester fiber terylene PET.
The fiber number of the ultra-fine short fiber of described acrylic fibers is preferably 0.9D-2.0D.
Described polyester filament total fiber number is 68D-100D, and step (2) obtains pin ply ground fabric through 28 pin-32 pin circular knitting machine weft knittings, and pin ply ground fabric openpore grammes per square metre is 55-65 gram/m.Super fine water thorn nonwoven fabric compared to existing technology, the present invention has following beneficial effect:
(1) existing acupuncture nonwoven the fabric little and color and luster of scope that can dye is comparatively dark, the wide and bright color of dyeing fabric scope of the present invention.
(2) existing water thorn nonwoven fabric elasticity is very little, and fabric elastic elongation of the present invention reaches 25%.
(3) existing water thorn nonwoven fabric tearing strength is low, and tearing strength of the present invention is greater than 70N.
(4) the many single use of existing water thorn nonwoven fabric, the present invention can repeated washing use.
(5) the polyurethane impregnation that " the skin sense " of existing imitation leather nonwoven fabric has to pass through mostly with DMF could realize, and the present invention does not need this processing just can realize " skin sense ", and soft, ventilative, high resilience.
(6) existing water thorn nonwoven fabric wearability is poor, and the present invention possesses most performance requirements such as the color fastness of high-grade clothing fabric, the anti-crape of anti-crape, sense, the resilience of hanging down.
