Problems solved by technology

[0004] During the use of diapers, the user is often in a state of motion. Ordinary diapers are prone to loosening, and the waist stickers are easy to turn outwards and rub against the skin. The skin appears red and swollen, and the waist appears stretched. shedding phenomenon
At present, some products use peritoneal elastic waist, the elasticity is rigid, too tight or too loose, and the air permeability is poor, especially in summer, the waist is prone to redness and swelling due to sweating
Or use glue to bond, but the glue will often cause skin irritation, skin allergies, redness and swelling, etc.
In addition, the back layer of disposable sanitary napkins, diapers and other products is not soft enough, making the position where it touches the skin uncomfortable

Embodiment 1

[0023] In this example, following the production process of the nonwoven fabric, after the nonwoven fabric is consolidated into a cloth, the nonwoven fabric 1 is fluffed by the licker-in roller 2 . Please refer to figure 2 As shown, the licker-in roller 2 is arranged with the needles 3, and the effect of the needles on the fluffing of the nonwoven fabric is adjusted by parameters such as the speed, needle density, needle length, and needle inclination angle. Several such licker-in rollers can be arranged on a production line. , Repeatedly fluffing the non-woven fabric. The fleece-like fibers of the fleece-like fiber layer on the surface of the non-woven fabric can protrude from the surface of the non-woven fabric to a length between 0.5 mm and 5 mm to meet the needs of most applications.

Embodiment 2

[0025] In this example, following the production process of the nonwoven fabric, after the nonwoven fabric is consolidated into a cloth, the nonwoven fabric 1 is fluffed through a mesh belt with needles. Please refer to image 3 As shown, needles 8 are arranged on mesh belt 7, and roller 5 and roller 6 are driven by motor, and roller 5 and roller 6 drive mesh belt 7; Parameter adjustment can change the effect of the needle on the fluffing of the nonwoven fabric.

Embodiment 3

[0027] In this example, the non-woven fabric 1 is fluffed through the fiber brush 9, and the fiber brush 9 may be composed of carbon fibers, or may be composed of metal fibers or other flexible and not easily broken fibers. The fluffing effect can be adjusted through parameters such as the frequency, speed, and size of the contact surface of the fiber brush 9 .

Abstract

The invention discloses a physically-modified non-woven fabric and a manufacturing method thereof. The physically-modified non-woven fabric is manufactured by forming a fluffy fiber layer on a non-woven fabric through physical modification and napping the fluffy fiber layer. As for the physically-modified non-woven fabric, processing is carried out after fabric formation, thus being easy to implement and having low production cost. Due to the fluffy fiber layer on the surface thereof, the physically-modified non-woven fabric has soft handle, and is affine and comfortable for human bodies; and by adopting a physical method to change the structure thereof instead of adopting a chemical additive for post-processing and other means to change the handle, and the fabric has safer materials.

Description

【Technical field】 [0001] The present invention relates to nonwoven fabrics. 【Background technique】 [0002] With the improvement of living standards, the market penetration rate of disposable hygiene care products such as baby diapers and adult incontinence pants is getting higher and higher, and people's requirements for them are getting higher and higher. Baby diapers and adult incontinence pants need continuous innovation and technological improvement to meet people's needs. [0003] In baby diapers and adult incontinence pants, Velcro and front adhesive are used to fasten the diaper, which is equivalent to the function of the belt in trousers. It is necessary for the Velcro and front adhesive to have a good fixing force and be easy to untie. . [0004] During the use of diapers, the user is often in a state of motion. Ordinary diapers are prone to loosening, and the waist stickers are easy to turn outwards and rub against the skin. The skin appears red and swollen, and...
