Example Embodiment
[0038] The preparation method of the above-mentioned spunlace composite non-woven fabric comprises the following steps:
[0039]S1. High-strength fiber web: Lay high-strength fibers into a web to prepare a high-strength fiber web;
[0040] S2. Viscose fiber web: laying viscose fibers into a web to prepare a viscose fiber web;
[0041] S3. Spunlace reinforcement: Laminate high-strength fiber webs and viscose fiber webs with a mass ratio of 9:1 to 5:5, and perform composite spunlace on the laminated composite fiber web to obtain a spunlace-reinforced composite non-woven fabric;
[0042] S4. Drying and molding: drying the spunlace-reinforced composite non-woven fabric, then winding, removing defects, slitting and packaging to obtain a spunlace composite non-woven fabric.
[0043] Preferably, in step S3, the composite spunlace adopts high-pressure water flow to perform 5-10 spunlace processes on the laminated composite fiber web, and the water needle pressure of each spunlace pro...
Example Embodiment
[0057] Example 1
[0058] The spunlace composite non-woven fabric provided in this embodiment is made of polyester fiber web and viscose fiber web with a mass ratio of 5:1 through spunlace reinforcement, and its surface density is 120g / m2 2 , the fineness of polyester fiber is 5dtex, and the fineness of viscose fiber is 0.8dtex, and its preparation method includes the following steps:
[0059] S1. Polyester fiber mesh: Lay polyester fibers with a fineness of 5dtex into a mesh to prepare a polyester fiber mesh;
[0060] S2. Viscose fiber mesh: Lay viscose fiber with a fineness of 0.8dtex into a mesh to prepare a viscose fiber mesh;
[0061] S3. Spunlace reinforcement: Laminate polyester fiber webs and viscose fiber webs with a mass ratio of 5:1, and use five spunlace processes to perform composite spunlace on the laminated composite fiber web to obtain a composite nonwoven reinforced by spunlace. cloth;
[0062] Among them, the water needle pressure P of the first spunlace p...
Example
[0064] Examples 2 to 11
[0065] The surface density, mass ratio, polyester fiber and viscose fiber fineness of the spunlace composite non-woven fabrics provided in Examples 2 to 11 are shown in Table 1. Among them, the preparation methods of Examples 2 and 3 and Examples 6 to 8 are shown in Table 1. All are substantially the same as those in Embodiment 1, and are not repeated here. The water needle pressures of the five spunlace processes of Example 4 are respectively 2MPa, 5MPa, 11MPa, 10.5MPa and 9.5MPa, and the water needle pressures of the five spunlace processes of Example 5 are respectively 2MPa, 5MPa, 14MPa, 13.5MPa and 12.5Mpa, and others are basically the same as those in Example 1, and will not be repeated here.
