Pump is measured, batch mixing is sent into manifold by measuring pump with certain pressure continuous uniform, and batch mixing fiber is made in batch mixing by manifold, to mixed
Expect that fiber carries out shredding combing, the batch mixing fiber combed is adhesively-bonded together to form to the nonwoven of fibre net structure by thermoforming
Cloth, while the uniform permeable hole for getting 50~70 mesh on hot-wind nonwoven cloth, completes the preparation of elastic pervious bed；
Step 2：Permeate the preparation of water lock layer：Pure cotton raw material required for selection, appropriate hydrophilic mother is added into pure cotton raw material
Material composition batch mixing fiber, carries out multilayer, the intersection of different directions to batch mixing fiber and lays, and carry out certain drawing-off to reinforce, obtain
To containing cotton fiber net, to carrying out spun lacing processing containing cotton fiber net, make, containing mutually tangling between cotton fiber, to form net containing cotton, profit
The moisture in net containing cotton is extruded with padding machine, kiering is carried out to net containing cotton, split shaping is carried out to the net containing cotton after kiering,
Secondary spun lacing and drying and processing are carried out to the net containing cotton after split shaping, are immersed in water repellent finish liquid, is rolled using two leachings two
Technique is padded, and the uniform permeable hole for getting 50~70 mesh on spun laced fabric containing cotton, finally drying, baking successively,
Obtain infiltration water lock layer；
Step 3：The preparation of the water lock that dehumidifies layer：Appropriate hot-melt fiber is added to obtained pure cotton raw material and carries out multilayer, difference
The intersection in direction is laid, and carries out certain drawing-off reinforcing, obtains containing cotton fiber net, to carrying out spun lacing processing containing cotton fiber net,
Make, containing mutually tangling between cotton fiber, to form net containing cotton, extrude the moisture in net containing cotton using padding machine, enter net containing cotton
Row kiering, split shaping is carried out to the net containing cotton after kiering, and dehumidifying water lock layer is made；
Step 4：Spun lacing Combined Processing：Elastic pervious bed is superimposed on infiltration water lock layer, composite material-feeding is formed, to Compound Fabric
Material carries out spun lacing and drying and processing, obtains semi-finished product；
Step 5：Band yarn stitching processing：In the intensive circular hole band yarn of bottom pad multilayer of dehumidifying water lock layer, semi-finished product are superimposed on and removed
The edge of semi-finished product and dehumidifying water lock layer, is uniformly stitched together, band yarn is hidden by wet water lock layer using 30D/24F low elastic polyester filaments
Ensconce in suture site, obtain finished product；
Step 6：Wind censorship：The progress winding containing cotton nonwoven fabrics prepared by step 5 is cut, and selects sample censorship, censorship
Packaging and storage after sample passes.
