Acupuncture suede, quantification of 100g/m is made in technique2。
The manufacture craft of the core cloth, including surface layer makes, basic unit makes and compound, the specific steps of surface layer and basic unit
It is：
（1）Surface layer makes：Using 85% polyethylene fiber peacekeeping 15%ES polyethylene fibres, ES fibers are bicomponent sheath cored structure
Composite fibre, two kinds of fibers are made polyethylene cloth by hot adhesion process and are used as surface layer, quantitative 15g/m2 ；
（2）The making of basic unit：Using 85% viscose rayon and 15% ES polyethylene fibres, ES fibers are bi-component sheath-core knot
Acupuncture suede, quantification of 100g/m is made by needling process in structure composite fibre, both fibers2；
（3）Ultrasonic wave is combined：Surface layer and basic unit are individually placed on two emptying rollers, and surface layer is upper, and basic unit places lower, warp
Two horizontally arranged jockey pulleys are crossed, taper ultrasonic wave set composite is delivered to, being combined into fabric front there are many round dots, and round dot is straight
0.5 ± 0.1 millimeter of footpath, the tapered depression of round dot, depth is 2.3-2.8 millimeters, and the spacing between round dot and round dot is 4 millimeters
Core cloth；
（4）Sizing hot pressing：After being combined into the core cloth of point-like conical indentation through ultrasonic wave, two spacing are delivered to for 2mm, temperature
Degree is hot pressed into the core cloth that thickness is 2.8-3.0 millimeters in 100 DEG C of ± 5 hot pressing rods.
It is an advantage of the invention that the cost of material is low, soaking effect is good, and water absorption rate reaches 6 times, and elongation percentage reaches 40-70%,
Feel spy is good.

Embodiment
Refer to shown in accompanying drawing, the present invention is made up of surface layer and basic unit, core cloth thickness is 2.8-3.0 millimeters, core cloth fabric
Front is evenly distributed with many round dots 1,0.5 ± 0.1 millimeter of 1 diameter of round dot, the tapered depression of round dot 1, and depth is 2.3-2.8 millis
Rice（As shown in Figure 2）, spacing between round dot and round dot is 4 millimeters, as shown in Figure 1, and round dot 1 is into square profile；Institute
Surface layer is stated using 85% polyethylene fiber peacekeeping 15%ES polyethylene fibres, ES fibers are bi-component sheath-core structure composite fiber, two kinds
Surface layer is made by hot adhesion process in fiber, quantitative 15g/m2 ；The basic unit uses 85% viscose rayon and 15% ES polyethylene fibers
Dimension, ES fibers are bi-component sheath-core structure composite fiber, and acupuncture suede is made by needling process in both fibers, quantification of
100g/m2。
Surface layer of the present invention is to use 85% polyethylene fibre, and 15%ES polyethylene fibres, ES fibers are bicomponent sheath cored structure
Composite fibre, cortical tissue's fusing point is low and flexibility is good, and then fusing point height, intensity are high for sandwich layer tissue, and this fiber is through Overheating Treatment
Afterwards, cortex a part melting and rise cementation remaining still retain fiber condition, both fibers are made up of hot adhesion process
Polyethylene cloth is as surface layer, quantitative 15g/m2 。
Basic unit of the present invention uses 85% viscose rayon and 15% ES polyethylene fibres, and ES fibers are multiple for bicomponent sheath cored structure
Condensating fiber, cortical tissue's fusing point is low and flexibility is good, and then fusing point is high for sandwich layer tissue, intensity is high, this fiber after Overheating Treatment,
Cortex a part melting and rise cementation remaining still retain fiber condition, acupuncture is made by needling process in both fibers
Suede, quantification of 100g/m2。
The manufacture craft of the present invention, refers to the process chart of accompanying drawing 3, combination process is：
The first step：Circular cone form point ultrasound point is compound
Fabric and base-material are individually placed to two emptying rollers, and it is coiled to enter circular cone form point ULTRASONIC COMPLEX by jockey pulley regulation.
Second step：Appropriate hot pressing, puts preliminary composite base material, into a pair of hot-pressing roller moderate-heats by circular cone form point ultrasound
Pressure, rod temperature is at 100 DEG C ± 5, and roll gap 2mm makes substrate forming stable.
The jockey pulley, is made up of the metallic roll of a pair of outpacking rubbers, can moderately be adjusted above and below the rod, it is therefore an objective to make into
