The specific embodiment
Coordinate shown in Fig. 1, Fig. 2, the utility model has disclosed a kind of nonwoven fabric, this nonwoven fabric is at least comprised of superficial layer 1 and nonwoven fabric enhancement layer 2, its key is: the viscose that this superficial layer 1 is the 30%-100% of 5-30 gram/m by grammes per square metre forms, and this viscose runs through described nonwoven fabric enhancement layer 2; This superficial layer 1 can be located at the upper and lower surface (as shown in Figure 2) of nonwoven fabric enhancement layer 2; And the viscose of this superficial layer 1 is hydrophily viscose or hydrophobicity viscose, and its grammes per square metre is preferably 5-20 gram/m, the viscose content of superficial layer 1 is preferably 70%-100%; This nonwoven fabric enhancement layer 2 is spun-bonded non-woven fabrics, hot-wind nonwoven cloth or fabric hot rolled nonwoven fabrics, and its grammes per square metre is 8-50 gram/m, is preferably 10-30 gram/m.
The manufacture method of the utility model non-woven viscose fabric, its concrete steps are:
Step 1, first by viscose superficial layer 1 after carding machine combing, lapping, be laid on nonwoven fabric enhancement layer 2 surfaces; If 1 of superficial layer arranges upper surface, combing one deck viscose superficial layer 1, if superficial layer 1 is arranged on upper and lower surface, needs the upper and lower two-layer viscose superficial layer 1 of combing to be laid on the strong layer of wall nonwoven fabric 2;
Step 2, secondly carry out single or double water thorn operation, the fine water jet of multiply that utilizes high pressure to produce sprays fibre web, in fibre web, fiber is under the interspersed hydraulic action of different directions high-speed water jet, produce displacement, intert, entanglement and obvolvent, thereby described superficial layer 1 fiber is fixed on nonwoven fabric enhancement layer 2;
Step 3, the nonwoven fabric after water thorn is processed are dried, rolling just forms non-woven viscose fabric.
Adopt water jet process by viscose and non-woven fabric compounded, the superficial layer of formation contains viscose to reach the requirement of soft-touch, as cotton goods class sense of touch; Adopt water jet process only to need the viscose of small amount just can reach the sense of touch of light water prick nonwoven cloth simultaneously, save viscose, cost is low; And the setting of nonwoven fabric enhancement layer makes this spunlace non-woven cloth have certain fracture strength, especially longitudinally powerful, can bear the pulling force that sanitary towel machine for example adds man-hour, can guarantee that it processes smoothly.The non-woven viscose fabric so forming can be applicable to the surface layer of the absorbing products such as sanitary napkin, paper diaper.
Example 1 is by the combing of 10gsm viscose process carding machine, after lapping, form viscose layer, and then be laid in the nonwoven surface of 10gsm, this nonwoven fabric can be hot-wind nonwoven cloth, a kind of in spun-bonded non-woven fabrics or fabric hot rolled nonwoven fabrics, then the fine water jet of multiply that utilizes high pressure to produce sprays fibre web, water jet is through after fibre web, be subject to the bounce-back of holding lace curtaining, again intert fibre web, therefore the fiber in fibre web is under the interspersed hydraulic action of different directions high-speed water jet, produce displacement, intert, tangle and obvolvent, thereby described superficial layer viscose is fixed on lower floor's nonwoven fabric, again through drying, the spunlace non-woven cloth that total grammes per square metre of the rolling formation upper strata 10gsm viscose 10gsm of lower floor nonwoven layer is 20gsm.
By XLW-100N Intelligent electronic tensil testing machine, carry out TENSILE STRENGTH detection, test parameter is as follows:
Width: 50mm, length: 100mm, draw speed: 100m/min
Test result is as follows:
| Sample title | TENSILE STRENGTH (N/50mm) |
| Light water prick nonwoven cloth, 20gsm | 15.5 |
| The utility model spunlace non-woven cloth, 20gsm | 28.6 |
By above test data, can be found out, at present common spunlace non-woven cloth is in the situation that grammes per square metre is lower, and mechanical property is very low, and upper machine is very poor, is difficult in amenities.So machine demand on the grammes per square metre of current light water prick nonwoven cloth generally all could meet more than 30gsm, must increase cost like this, has limited its application in amenities.
And the spunlace non-woven cloth of the utility model patent is due to the existence of nonwoven fabric enhancement layer, the in the situation that of identical grammes per square metre, mechanical property obviously improves, and can meet upper confidential asking, and surface also has the cotton soft sense of touch of light water prick nonwoven cloth.And cost is because adhesive-layer grammes per square metre is compared with low and obviously reduce, must extensively be used in amenities.
Example 2 is by 100% hydrophobicity viscose process carding machine combing, after lapping, form the fibrage of 10gsm, and then be laid on the hydrophilic spun-bond nonwoven fabric surface of 20gsm, then the fine water jet of multiply that utilizes high pressure to produce sprays fibre web, water jet is through after fibre web, be subject to the bounce-back of holding lace curtaining, again intert fibre web, therefore the fiber in fibre web is under the interspersed hydraulic action of different directions high-speed water jet, produce displacement, intert, tangle and obvolvent, thereby described superficial layer viscose is fixed on spun-bonded non-woven fabrics enhancement layer, again through drying, it is 30gsm that rolling forms grammes per square metre, the spunlace non-woven cloth of the hydrophobic viscose of the upper strata 10gsm 20gsm of lower floor hydrophilic spun-bond nonwoven fabric.
This spunlace non-woven cloth is because superficial layer is comprised of 100% viscose, and what combing mixed is more prone to, and sense of touch is more cotton soft, and skin-friendly is better.And the viscose of superficial layer is hydrophobic fibre, in actual use, so can penetrate rapidly this spunlace non-woven cloth under gravity and the poor effect of surface energy level when body fluid arrives this spunlace non-woven cloth surface layer, arrive absorber, and because upper strata is hydrophobic, lower floor is hydrophilic, so hydrophobicity viscose can stop body fluid again to turn back to this spunlace non-woven cloth surface layer, thereby can effectively reduce the sense of surface layer tide, reach dry and comfortable object.The mechanical property of the spun-bonded non-woven fabrics of lower floor itself is better than hot-wind nonwoven cloth and fabric hot rolled nonwoven fabrics, as the enhancement layer of this spunlace non-woven cloth, more can play raising mechanical property, prevents the effect of machine distortion.Therefore, this spunlace non-woven cloth can be for the surface layer of the amenitiess such as sanitary napkin, paper diaper.
Example 3 adopts viscose that two carding machines or many carding machines mix 100% viscose or 30%-100% respectively after carding machine combing, lapping, form respectively the fibrage of 5-30gsm, and then be laid in respectively surface or the bottom that grammes per square metre is 8-50 gram/m of nonwoven fabric, but wherein have at least one deck viscose fiber to be placed in the top layer of nonwoven fabric, and nonwoven fabric enhancement layer can be hot-wind nonwoven cloth, spun-bonded non-woven fabrics or fabric hot rolled nonwoven fabrics.Then the fine water jet of multiply that utilizes high pressure to produce sprays fibre web, water jet is through after fibre web, be subject to the bounce-back of holding lace curtaining, again intert fibre web, therefore the fiber in fibre web is under the interspersed hydraulic action of different directions high-speed water jet, produce displacement, intert, entanglement and obvolvent, thereby described viscose and nonwoven fabric enhancement layer are fixed, then through drying, rolling formation MULTILAYER COMPOSITE spunlace non-woven cloth.
This spunlace non-woven cloth superficial layer is viscose, have the sense of touch of cotton class, and nonwoven fabric enhancement layer can be gained in strength, and is conducive to machine moulding, and can save spunlace non-woven cloth cost.
