Detailed Description

Referring to fig. 1 to 5, an elastic waistline comprises a surface layer 1 and a bottom layer 2, rubber strings 3 arranged between the surface layer 1 and the bottom layer 2, wherein the rubber strings 3 are arranged above the bottom layer 2 in parallel, hot melt adhesives 4 used for fixing the rubber strings 3 are arranged on the bottom layer 2, a plurality of point-breaking areas 5 of the rubber strings 3 are arranged on the bottom layer 2 at intervals, the point-breaking areas 5 are 10-15mm, the hot melt adhesives 4 are arranged above the bottom layer 2 at intervals, and the hot melt adhesives 4 are fixedly arranged on two adjacent rubber strings 3. Four edges of the surface layer 1 and the bottom layer 2 are fixedly connected with each other through ultrasonic welding. Apply hot melt adhesive 4 through the interval, make some subregion 5 do not contain hot melt adhesive 4, two adjacent rubber bands 3 set up the department and arrange hot melt adhesive 4, when saving the process, hot melt adhesive 4 glue application volume is less, makes elastic waist reach softer level, and two adjacent rubber bands 3 produce inside stress during the use, make the laminating degree better, improve user's comfort in use.

Surface course 1 and bottom 2 are the super gentle non-woven fabrics that the alignment fifty percent discount of mutual border formed. The hot melt adhesive 4 is n-shaped. 1 fixed connection magic subsides 6 of surface course, 2 below fixed basement membranes 7 that set up of bottom layer, wherein basement membrane 7 sets up core 71, laminates in the permeable layer 72 of core 71 top, the matte 73 of pasting corresponding with magic subsides 6, distributes in the leak protection of both sides and separates limit 74.

A method for manufacturing elastic waistline comprises the following steps,

a) spreading the super-soft non-woven fabric on a platform, and arranging a plurality of rubber bands 3 above one side of the super-soft non-woven fabric in parallel;

b) pressing and limiting the rubber band 3;

c) applying hot melt adhesives 4 to the rubber bands 3 at intervals, wherein the hot melt adhesives 4 are arranged at intervals and adhere to two adjacent rubber bands 3;

d) performing interval point breaking on the rubber band 3 to form a plurality of point breaking areas 5, wherein the point breaking areas 5 are 10-15 mm;

e) and after the point breaking is finished, the other side of the ultra-soft non-woven fabric is turned over and attached to the rubber band 3 to form a surface layer 1 and a bottom layer 2 which are respectively positioned at the upper part and the lower part. The edges of the surface layer 1 and the bottom layer 2 are fixedly connected with each other through ultrasonic welding. And c) forming an acute angle by applying the hot melt adhesive 4. And c), gluing the hot melt adhesive 4 in the step c for 15-20mm, wherein the hot melt adhesive 4 is applied at intervals of 10-15 mm. The edges of the surface layer 1 and the bottom layer 2 are fixed for 5-8 mm.

Punch before super gentle non-woven fabrics compounds the rubber band and form a plurality of through-hole 8, wherein the aperture that leads to 8 holes is 1-2mm, tensile back aperture increase during the use is to 2-4mm, wherein the distribution of through-hole 8 is multirow mutual parallel distribution, make the gas permeability reinforcing of this super gentle non-woven fabrics through-hole 8, the interval of punching is 10-12mm, wherein through-hole 8 is the range of slant alignment mode, the range of slant alignment mode can not influence each other between each through-hole after stretching elastic waistline in the user use, can reach the increase diameter, increase the ventilation capacity, it is stronger to make the gas permeability through punching, improve user comfort level.

The some fault zone 5 that does not glue and do not have rubber band 3 position is the cavity state, surface course 1 forms the cavity that the multirow has certain radian with bottom 2 laminating back point fault zone 5 each other, because the cavity does not set up rubber band 3 and hot melt adhesive 4, when the cavity laminates each other with the user, the gas permeability is good, apply rubber band 3 through the multiple spot, make a plurality of elastic regions of elastic waistline distribution, multiple spot elasticity makes elastic waistline laminating degree higher, avoid among the prior art local elasticity too big can produce to draw tightly, the condition that influences user's wearing comfort level relatively takes place. The n-shaped glue application reduces the glue application amount, reduces the glue application amount at the rubber band 3 arrangement position and improves the air permeability of the elastic waistline.

The utility model discloses in: apply hot melt adhesive 4 through the interval, make some subregion 5 do not contain hot melt adhesive 4, two adjacent rubber bands 3 set up the department and arrange hot melt adhesive 4, when saving the process, hot melt adhesive 4 glue application volume is less, makes elastic waist reach softer level, and two adjacent rubber bands 3 produce inside stress during the use, make the laminating degree better, improve user's comfort in use.
