Detailed ways

As shown in FIG1 , the high-slit anti-leg-binding disposable underwear disclosed in the present invention comprises:

The outer layer 10 comprises a front waist piece 101 and a rear waist piece 102, and the two sides of the front waist piece 101 are respectively connected to the two sides of the rear waist piece 102; the two leg circumferences of the front waist piece 101 are both provided with high crotch areas, and the straight-line distance between the highest point of the high crotch area and the upper waist edge of the outer layer 10 is a first spacing h, and the straight-line distance between the lowest point of the crotch of the outer layer 10 and the upper waist edge of the outer layer 10 is a second spacing H, satisfying h/H=0.2-0.3, and H is specifically the straight-line distance from the center point of the crotch of the disposable underwear to the upper waist edge after it is unfolded;

The leg edges of the front waist panel 101 and the back waist panel 102 are both continuously extended wavy edges, and the wavy edges can be made through a pattern cutting process. Pattern cutting is a technology that cuts and forms patterns or designs on fabrics, usually on materials such as textiles, cloth or leather to achieve the desired structure.

Furthermore, in this embodiment, the first spacing h is 25-40 mm, the second spacing H is 100-160 mm, and the slit angle of the high slit area is 80°-120°. From the above dimensions and angles, it can be seen that by increasing the opening length, it can fit the leg curve, play a role of anti-slip and fixing, prevent the disposable underwear from moving, and not squeeze the thigh root, no curling, no mark and more comfortable to wear.

Furthermore, in this embodiment, the outer layer 10 includes a laminated first interlayer and a second interlayer, and a plurality of elastomers are laminated between the first interlayer and the second interlayer; the laminated first interlayer and the second interlayer are made of soft non-woven fabrics, that is, double-layer non-woven fabrics are laminated with a plurality of elastomers, and the double-layer non-woven fabrics mainly use double-layer soft non-woven fabrics. For the double-layer soft non-woven fabrics used, the double-layer soft non-woven fabrics are usually made of soft fiber materials, which are comfortable to the skin and have good air permeability, which helps to keep the contact parts dry and comfortable, and the non-woven fabrics usually have good moisture absorption, can quickly absorb and eliminate sweat, keep the disposable underwear dry, and reduce the possibility of odor and bacterial growth; the double-layer non-woven fabrics usually have good air permeability, can allow air to flow, avoid moisture retention, and help to keep the contact parts fresh and breathable and comfortable; the double-layer structure can also enhance the durability of disposable underwear, reduce the wear and deformation of the fabric, and extend the service life.

The elastic body extends along the width direction of the outer layer 10, and a plurality of the elastic bodies are arranged in a direction from the upper waist to the crotch. The elastic body can be made of fine-denier elastic, elastic film, or elastic cloth. Since the elastic body itself is elastic, it can be stretched and contracted freely, making the overall feel softer and more comfortable. In addition, since the outer layer 10 is elastic, the force-bearing area is wide and the force is dispersed, and the tightness can be automatically adjusted according to the body shape of the consumer, avoiding the concentration of force that affects the wearing comfort, and can effectively avoid the phenomenon of strangulation marks during wearing, so as to enjoy a seamless naked feeling experience.

Furthermore, in this embodiment, the leg circumference of the rear waist piece 102 is an arc shape with an arc of 170° to 180°. The arc shape can achieve full coverage without pinching the hips, can accommodate large and small hips, widen the cut to protect the hips, fit the human body more closely, and be comfortable without pinching the hips.

Furthermore, in this embodiment, the elastomer is connected between the first interlayer and the second interlayer by hot melt adhesive, and the ratio of the elastomer is 1.6 to 2.8 times. The leg circumference contour of the above-mentioned rear waist panel 102 is an arc shape, and the elastic body can be freely stretched and contracted, so that the disposable underwear can fit and wrap the human buttocks curve, and can accommodate both large and small buttocks. This further solves the problem that the underwear is easily displaced or narrowed during use due to the narrow back piece of the leg being unable to fully wrap the buttocks, thereby causing the buttocks to be clamped.

Furthermore, in this embodiment, the upper waist edge of the outer layer 10 is provided with a plurality of adhesive application areas spaced along both sides of the outer layer 10, and hot melt adhesive is coated in the adhesive application areas for connecting the elastic body to the first interlayer and the second interlayer respectively, so that the elastic body and the first interlayer and the second interlayer form an intermittent adhesive structure, which can make the upper waist fluffy and comfortable to contact with the human body without leaving any marks;

In order to make the upper waist more comfortable and seamless when in contact with the human body, a lace band can be set at the edge of the upper waist. The lace band combined with the structure of the fluffy waist makes the underwear comfortable and leaves no marks when in contact with the human skin. The lace band can be a straight-edge lace band, the edge of which is straight and can be used for edge decoration of textiles; it can be a serrated-edge lace band, the edge of which is serrated, similar to alternating semicircles and pointed shapes; it can be a wavy-edge lace band, the edge of which is wavy; it can be a wavy-edge sutured lace band, the edge of which is connected by wavy sutures; the specific shape is selected according to actual conditions. The setting method can be sewing or gluing. Sewing is the most common fixing method. Use a sewing machine or hand sewing to sew the lace band to the waistline of the underwear. This method is usually more durable and can ensure that the lace band is not easy to loosen. For gluing, use special adhesives or hot melt adhesives to stick the lace band to the underwear. This method is fast and easy to operate, but the durability of the adhesion may be slightly worse than sewing. The specific choice depends on the actual situation.

Furthermore, in this embodiment, the lengths of the connecting sections on both sides of the front waist panel 101 and the back waist panel 102 are both 50 to 90 mm, which reduces the contact area of the waist and reduces the sense of restraint on the waist; the front waist panel 101 and the back waist panel 102 are connected on both sides to form a side waistline, and the two sides are connected by ultrasonic pressing technology without any sewing lines, thereby reducing the friction of the waistline seams that fit on both sides of the body on the skin, and the seamless naked feeling is more comfortable to wear.

Furthermore, in this embodiment, the outer layer 10 is a double-layer non-woven fabric, and a plurality of elastomers are compounded in the middle, specifically a double-layer soft non-woven fabric, and a layer of ultra-fine elastic or elastic film or elastic cloth is compounded in the middle, so that the outer layer 10 itself has a certain elasticity and can be stretched and contracted freely, which makes the overall feel softer and more comfortable than directly compounding thicker elastic or wide white elastic elastic bands and other materials. In addition, since the entire outer layer is elastic, the force-bearing area is wide and the force is dispersed, the tightness can be automatically adjusted according to the body shape of the consumer, avoiding the concentration of force that affects the wearing comfort, and can effectively avoid the phenomenon of strangulation marks during wearing, and enjoy a seamless naked feeling experience. Combined with the semicircular arc profile of the above-mentioned rear waist panel 102, and the double-layer non-woven fabric composited with a number of elastic bodies, it can stretch and shrink freely in the lateral direction, and the stretching ratio is relatively high, about 1.6-2.8 times, so it can better fit and wrap the human buttocks curve, and can accommodate both large and small buttocks. It solves the problem that the rear waist panel 20 is narrow and the leg circumference of the rear waist panel 102 cannot fully wrap the buttocks, causing the underwear to easily move out of place or narrow during use, thereby pinching the buttocks.

Furthermore, in this embodiment, the high-slit anti-leg-binding disposable underwear also includes:

The inner layer 20 is bonded to the inner surface of the outer layer 10 by hot melt adhesive and is located at the crotch position. The hot melt adhesive bonding makes the connection between the inner layer 20 and the outer layer 10 seamless and non-abrasive; hot melt adhesive bonding is a common method for connecting fabrics, and its advantages are: fast bonding speed, suitable for automated high-speed operation, solvent-free, highly environmentally friendly, simple bonding process, good bonding strength and toughness, and a wide range of applications. At present, hot melt pressure-sensitive adhesive has been widely used in women's sanitary napkins, children's diapers, bed mattresses, elderly incontinence products, etc. It is odorless, non-toxic, and does not irritate the skin. The hot melt adhesive bonding process has been accepted by the public; in addition, hot melt adhesive has no solvent consumption, avoiding the deformation, dislocation and shrinkage of the adherends due to the presence of solvents, which helps to reduce costs and improve product quality.

Furthermore, in this embodiment, the inner layer 20 is a mesh cotton material. The mesh cotton material is a mesh pure cotton spunlace fabric, which is a common type of fabric, breathable and comfortable, and the pure cotton material can give the user a softer and more comfortable feeling, can absorb human secretions well, and quickly dissipate excess moisture; in addition, the mesh material can enhance the breathability and perspiration-wicking function of the material, especially when used in summer, it can ensure comfort without stuffiness.

The working process of the high-slit anti-leg-binding disposable underwear of this embodiment will be fully described below in combination with the above content.

Firstly, the high-slit anti-leg-binding disposable underwear has an outer layer 10, which includes a first interlayer and a second interlayer that are laminated and compounded, and a plurality of elastomers are compounded between the first interlayer and the second interlayer; the laminated and compounded first interlayer and second interlayer are made of soft non-woven fabric, that is, a double-layer non-woven fabric is compounded with a plurality of elastomers, and the double-layer non-woven fabric mainly uses a double-layer soft non-woven fabric, and a plurality of elastomers are compounded in the middle, and the elastomer can be selected from fine-denier rubber bands, elastic films, or elastic cloth, so that the outer layer 10 has elasticity and can be stretched and contracted freely. Both leg circumferences of the front waistline piece 101 are provided with high split areas, and the straight-line distance between the highest point of the high split area and the upper waistline edge of the outer layer 10 is a first spacing h, and the straight-line distance between the crotch of the outer layer 10 and the upper waistline edge of the outer layer 10 is a second spacing H, satisfying h/H=0.2-0.3. The high split fits the leg curve better and is more comfortable to wear. The above-mentioned first spacing h is 25-40 mm, the second spacing H is 100-160 mm, and the split angle of the high split area is 80°-120°; the leg circumference profile of the rear waistline piece 102 is an arc shape with an arc of 170°-180°. The rear waistline piece 102 adopts a full-coverage non-hip clamping process. The widened cut can protect the buttocks, fit closer to the human body, and be comfortable without pinching the buttocks. In addition, the double-layer non-woven composite elastomer used can be freely stretched and contracted in the lateral direction, with a stretching ratio of 1.6-2.8 times, which can better fit and wrap the human buttocks curve, and can accommodate both large and small buttocks. This solves the problem that the disposable underwear is easily displaced or narrowed during use due to the narrow rear waistline piece 20 that cannot fully wrap the buttocks, thereby causing the buttocks to be pinched; the leg circumferences of the front waistline piece 101 and the rear waistline piece 102 are cut to form a wavy curve structure, and the cutting is performed by a flower cutting process, that is, lace-shaped cutting is used at the leg circumference, so that the thighs are not squeezed when worn.

Next, the upper waistline edge of the outer layer 10 is arranged with multiple adhesive application areas at intervals along both sides of the outer layer 10, and hot melt adhesive is coated in the adhesive application area for connecting the elastic body to the first interlayer and the second interlayer respectively, so that the elastic body and the first interlayer and the second interlayer are intermittently adhesively bonded. This structure can make the upper waistline fluffy and comfortable and seamless when in contact with the human body; a lace belt can also be provided at the upper waistline of the outer layer 10, and the lace belt is provided at the upper waistline, which is comfortable and seamless. The two sides of the front waistline piece 101 are respectively connected to the two sides of the back waistline piece 102 by ultrasonic lamination, and the connection point is the side waistline. The length of the connecting section on both sides is 50 to 90 mm, which reduces the contact area of the waist and reduces the sense of restraint of the waist. There is no sewing line, which reduces the friction of the waistline sutures on both sides of the body on the skin, and it is more comfortable to wear without a trace.

Then, the disposable underwear also has an inner layer 20, which is adhered to the inner surface of the outer layer 10 and is located at the crotch position. The inner layer 20 is adhered to the inner surface of the outer layer 10 by using hot melt adhesive, and the hot melt adhesive is used to make the connection between the inner layer 20 and the outer layer 10 seamless and non-abrasive. The inner layer 20 is made of mesh cotton material, which is mesh cotton spunlace fabric. Mesh cotton spunlace fabric is a common type of fabric with air permeability and comfort. The pure cotton material can give the user a softer and more comfortable feeling, can absorb human secretions well, and quickly dissipate excess moisture; in addition, the mesh material can enhance the material's breathability and sweat-wicking function, especially when used in summer, it can ensure comfort without stuffiness.

Finally, the outer layer 10 is made of double-layer non-woven composite elastic body, seamless adhesive process, and the side waistline uses ultrasonic lamination technology without any sewing lines, which reduces the friction of the waistline suture line on the side of the body against the skin, and it is more comfortable to wear without traces; the leg circumference of the front waistline piece 101 adopts a high-slit profile, which does not squeeze the thigh root; the leg circumference edges of the front waistline piece 101 and the back waistline piece 102 are both continuously extended wavy edges, and the wavy edges are cut in a lace shape, and they do not squeeze the thighs when worn; the leg circumference of the back waistline piece 102 is fully covered without clamping the hips, and can accommodate large and small hip circumferences. High-slit anti-leg-squeezing disposable underwear has a seamless naked feeling experience, seamless adhesive process, soft and skin-friendly, that is, comfortable and seamless.
