Wheel 8 pull-out, wherein, wheel speeds is: roller 8 > roller 7 > roller 6 > roller 5 > roller 4, the speed of roller 4 is more than casting films stream
Prolonging speed, after 5 step stretchings, not only film product is thinner, and can form structure as shown in Figure 4, wherein 1 produces for this example
Product high-hydroscopicity thin film, 2 is SAP granule, and 9 is the holes that stretching produces.
Step S4: mechanical punching.Cast film after stretching is carried out by a pair intermeshing perforated roll device
Mechanical punching, pass can be circular hole, square hole, hexagon etc., for ease of absorbing water faster, can carry out beating on thin film
Hole.This example mesoporous selects 2mm circular hole.
This example product high-hydroscopicity membrane structure schematic diagram is as it is shown in figure 5,1 be wherein thin film, and 2 is SAP granule, and 3 are
The perforate formed after mechanical punching, 9 is the holes that stretching produces.On the basis of example two, add stretching holes step, produce
Product thickness diminishes so that this perforate water-absorbing film ensure absorb liquid permeation rate, breathability and flexible while, keep
The distinctive slim and graceful advantage of thin film.
In the application of this finished product, enlarged diagram is as shown in Figure 6: wherein 10 is perforated non-woven fabric or punching PE film, and 11 are
Ultra-thin sponge, 1 is this example product high-hydroscopicity thin film, and 12 is waterproof ventilated membrane.Ground floor perforated non-woven fabric or PE film, as
Surface layer, can directly contact skin, have the features such as hydrophilic, liquid permeability, pliability and skin-friendly；The second layer is ultra-thin sponge,
Purpose is for increasing product breathability, sense comfortable and easy to wear, stickiness, and this example is chosen 2mm polyurethane sponge, had preferable softness
Property and bigger percent opening；Third layer is water absorption thin film, because the thin film of this example is PE thin film, and thickness only 0.8mm, only pass
System Time of Fluff Slurry and the 1/5 of dust-free paper absorbed layer, greatly reduces product thickness, and additionally PE film has preferable toughness and water suction not
Dispersion, in use will not produce fracture and the problem such as agglomerating that absorbs water.4th layer is waterproof and breathable counterdie.
