In addition, since the upper elastic member is a film-like member, it does not have a great influence on the air permeability, and since the upper elastic member is provided with the waist nonwoven fabric, the waist nonwoven fabric is contracted when it is contracted, and the contraction forms fine wrinkles, but the wrinkles are smaller and smoother than those of the elastic band, and the fine wrinkles can improve the air permeability; the width of the upper elastic piece is not large, the upper elastic piece is usually set to be 10-30 mm, and the specific size is adjustable, so that the width does not influence the air permeability; in addition, the air permeability can be improved by punching the upper elastic piece; in addition, the elastic piece can be provided with a convex part, and the hole is arranged in the convex part, thereby realizing the improvement of air permeability, reducing the bound area and not reducing the wearing effect.
The manufacturing process of the composite elastic waistline pull-up pants comprises the following steps:
firstly, preparing an absorption main body;
secondly, preparing an upper waistline part, compounding an upper elastic piece with waist non-woven fabric, wherein the upper waistline part is compounded with the waist non-woven fabric after the upper elastic piece is rolled and stretched by a, spraying b first glue b1 on one side of the upper elastic piece before compounding to realize the primary bonding of the upper elastic piece 51 and the waist non-woven fabric 52, then rolling c to realize compounding, folding d the waist non-woven fabric, spraying e second glue e1 on one side of the upper elastic piece simultaneously to ensure that the folded waist non-woven fabric 52 is compounded with the other side of the upper elastic piece 51 again through rolling f to prepare the upper waistline part, the upper elastic piece 51 is coated in the waist non-woven fabric 52, two ends of the waist non-woven fabric 52 exceed the upper elastic piece 51 and are combined to form a waistline connecting piece 53, one end of the waist non-woven fabric 52 extends out of the waistline connecting piece 53 to form a covering ring 54, refer to fig. 11, 12;
thirdly, inputting the outer cover layer, the inner cover layer, the elastic rubber band and the upper waistline portion, so that the elastic rubber band 41 is clamped at two ends of the outer cover layer 1 and the inner cover layer 2 in the width direction to form the lower waistline portion 4, the upper waistline portion 5 is connected to the outer side of the lower waistline portion 4, and the cover 54 covers the lower waistline portion 4, referring to fig. 12 and 13;
fourthly, adhering the absorption main body;
fifthly, folding to enable the two ends of the outer covering layer and the inner covering layer in the width direction to be folded;
sixthly, welding, wherein two ends of the lower waistline part and the upper waistline part which are positioned on one side of the absorption body are respectively fixedly connected with the lower waistline part and the upper waistline part which are positioned on the other side of the absorption body to form a connecting part, the connecting part is formed in an ultrasonic welding mode, and a plurality of sewing holes are formed in the part of the upper elastic piece, which is positioned on the connecting part;
and seventhly, cutting, namely cutting the connecting part to obtain the single pull-up diaper.
The above steps are only a brief step, and some steps are omitted, for example, in the fourth step, the opening of the leg hole may be performed before or after the main absorbent body is adhered, but it is not an essential step, and in the process of making the pull-up pants, there may be a process of not opening the leg hole, which is naturally formed after being folded. The steps are necessary steps, and other steps can be added according to needs, such as an S-shaped rubber band adding step, an anti-side leakage rubber band adding step and the like.
In the second step, the adjustment may be made according to the actual wrapping manner of the waist nonwoven fabric and the elastic member. In the third step, the adjustment may be performed according to the actual connection manner between the upper waistline portion and the lower waistline portion. In the second step, the folding of the waist nonwoven fabric is assisted by a plurality of guide rollers, wherein d is one of the guide rollers, d1 is the other guide roller, and other guide rollers can be arranged.
After the third step is completed, the joined upper waistline portion and lower waistline portion still need to be rolled, and the rolling device in this case cannot be a common pressing roller mechanism, and in this embodiment, as shown in fig. 14, the rolling device includes an upper roller 91, a lower roller 92, and a driving mechanism for driving the upper roller 91 and the lower roller 92, an upper recess 911 for avoiding the upper waistline portion is provided on the upper roller 91, and a lower protrusion 921 for supporting the upper waistline portion is provided on the lower roller 92. This arrangement makes it possible to effectively roll the connection of the upper and lower waistline portions shown in fig. 12.
