Problems solved by technology

In the application of diapers and sanitary napkins, in order to prevent urine and menstrual blood from leaking along the edges of diapers and sanitary napkins, some people have developed a variety of anti-side leakage diapers and sanitary napkins. The surface of the sanitary napkin is provided with diversion grooves, and there are structures such as raised guards on both sides of the diapers and sanitary napkins, but these anti-side leakage structures have their disadvantages. When sports or other situations make the body in close contact with the sanitary napkin, the raised guard will be pressed against the surface of the diaper and sanitary napkin, losing the anti-side leakage function
Some people have invented spunbond nonwoven fabrics for diapers and sanitary napkins, and SMS nonwoven fabrics are used to glue the leak-proof partitions on both sides. Meltblown+Spunbond) non-woven bonding will cause many problems, such as peeling, glue bleeding, etc., and the process is complicated and the cost is high

Embodiment 1

[0027] The nonwoven material of "SMMS"+"SS"+"SMMS" structure and its manufacturing method:

[0028] Such as figure 1 As shown, the process equipment includes the first spunbond equipment 1 and the second spunbond equipment 2, the first meltblown equipment 3 and the second meltblown equipment 4; the first spunbond equipment spins to form the first spunbonded fiber web 5, The second spunbond equipment spinning forms the second spunbond fiber web 6; the first melt-blown fiber web 7 formed by the first melt-blown equipment spinning, and the second melt-blown fiber web 8 formed by the second melt-blown equipment spinning; The first spunbonded fiber web, the first melt-blown fiber web, the second melt-blown fiber web and the second spunbond fiber web are laminated and hot-rolled by a hot rolling mill to form an SMMS spunmelt nonwoven fabric 9 . Among them, the first and second melt-blown equipment are composed of multiple small-width melt-blown equipment arranged at certain interva...

Embodiment 2

[0030] The nonwoven material and manufacturing method of the "SSS"+"SMSMS"+"SSS" structure of this example:

[0031] refer to figure 1 As shown, on the basis of embodiment 1, the third spunbond equipment is installed between the first and second meltblown equipment, and the third spunbond equipment spins to form the third spunbonded fiber web; the first spunbond The bonded fiber web, the first melt-blown fiber web, the third spunbond fiber web, the second melt-blown fiber web and the second spunbond fiber web are bonded to form a discontinuous spunmelt nonwoven fabric of SMSMS structure, that is, according to "SSS "+"SMSMS"+"SSS"+...+"SMSMS"+"SSS"+"SMSMS" regular arrangement. Width can be set as required. can be cut into image 3 As shown in the small width, the material after slitting has SMSMS structure on both sides, and the middle material is SSS structure.

Embodiment 3

[0033] The nonwoven material and manufacturing method of the "SS"+"SMMMS"+"SS" structure in this example:

[0034] refer to figure 1 As shown, on the basis of Example 1, the third melt-blown equipment is installed between the first and second melt-blown equipment, and the third melt-blown fiber web formed by the spinning of the third melt-blown equipment; The spunbonded fiber web, the first meltblown fiber web, the third meltblown fiber web, the second meltblown fiber web and the second spunbond fiber web are bonded to form a discontinuous spunmelt nonwoven fabric of SMMMS structure, that is, according to " SS"+"SMMMS"+"SS"+...+"SMMMS"+"SSS"+"SMMMS" are arranged regularly. Width can be set as required. can be cut into Figure 4 In the small width shown, the material after slitting is SMMMS structure on both sides, and the middle material is SS structure.

Abstract

The invention discloses a discontinuous type SMS melt spun nonwoven material and a preparation method thereof. The nonwoven material comprises an upper first spun-bonded fibre web, a lower second spun-bonded fibre web and a first melt-blown fibre web, wherein the first melt-blown fibre web contains a plurality of melt-blown fibre webs with small breadth, and the melt-blown fibre webs with small breadth are discontinuously distributed between the first spun-bonded fibre web and the second spun-bonded fibre web. The spun-bonded nonwoven material of the invention has the special multi-layer structure with the spun-bonded fibre webs (S) and the melt-blown fibre web (M) and can be freely cut into multiple pieces with small breadth along the transverse breadth direction; when used in hygienic products such as personal care diapers and sanitary towels, leak guards with SMS nonwoven structure can be formed on both sides of the hygienic products, thus solving the lateral leakage problem of products; and the defects of the existing technology that the adhesive technology is used to cause adhesive leakage, the process is complex, the cost is high, the product quality is not stable, etc.

Description

【Technical field】 [0001] The invention relates to a structure and process of a nonwoven material. 【Background technique】 [0002] Spunmelt nonwovens are more and more widely used in personal care and other hygiene materials, especially in the application of diapers and sanitary napkins, and bottom films. In the application of diapers and sanitary napkins, in order to prevent urine and menstrual blood from leaking along the edges of diapers and sanitary napkins, some people have developed a variety of anti-side leakage diapers and sanitary napkins. The surface of the sanitary napkin is provided with diversion grooves, and there are structures such as raised guards on both sides of the diapers and sanitary napkins, but these anti-side leakage structures have their disadvantages. When sports or other situations make the body in close contact with the sanitary napkin, the raised guard will be pressed against the surface of the diaper or sanitary napkin, losing the function of p...
