Problems solved by technology

[0007] From the above comparison, it can be seen that the elongation at break of spunbonded spunlace nonwovens is much greater than that of needled nonwovens, and the tensile deformation is relatively large, so it is not suitable for furniture, sofas, and mattress spring wraps.

Embodiment 1

[0032] In this example, a method for preparing a spunbond fabric is provided. The preparation method of this example can prepare a high-strength and low-stretch spunbond fabric, which can be placed in furniture, sofas, seats, etc. . The preparation method of this embodiment can not only prepare spun-bonded fabrics, but also non-woven fabrics of other materials.

[0033] Such as figure 1 As shown, the spunbonded fabric of the present embodiment passes through screw extruder 1, spinning machine 2, web laying machine 3, jet spunlace spunlace machine 4, dryer 5, drafting machine 6, heat-setting by expansion Machine 7 and winding machine 8 are prepared. This example takes the preparation of spunbonded polypropylene spunlace fabric as an example. This preparation method can also prepare spunbonded polypropylene needle-punched fabric, spunbonded polyester spunlace non-woven fabric, spunbonded polyester needle-punched non-woven fabric, or other fiber spunbond nonwovens.

Abstract

The invention discloses a spunbond and a preparation method thereof. The preparation method of the spunbond includes the steps: hot melting extrusion; spinning; lapping; reinforcement and fabric formation; drying; longitudinal drafting, to be specific, conveying the dried spunbond to a drafting machine for longitudinal drafting; spreading and heat-setting, to be specific, conveying the longitudinally drafted spunbond to a spreading and heat-setting machine for transverse spreading and heat-setting; winding, to be specific, conveying the spread and heat-set spunbond to a winding machine for winding the spunbond into a finished product. As the spunbond is dried, sequentially longitudinally drafted, transversely spread and heat-set in the preparation process, the structure of the spunbond ismore stable, longitudinal and transverse drafting is uniform, longitudinal and transverse gram weight distribution is uniform, and the spunbond has high strength, low elongation strain and accordinglyapplicable to industries of furniture, sofas, seats and the like.

Description

technical field [0001] The invention relates to the field of nonwovens, in particular to a spunbond fabric and a preparation method thereof. Background technique [0002] Spunbond spunlace nonwoven technology can combine the advantages of spunbond nonwovens and spunlace nonwovens. The product has high strength and soft hand feeling, which is close to traditional textiles. Therefore, it has a very wide range of uses and can be applied to high-end wipes , medical and hygiene and personal care products and other fields, the production technology of spunbond spunlace nonwovens represents the most advanced level of nonwovens technology development in the world. With the development and application of new products of spunbond spunlace nonwovens, spunbond spunlace Spunlace nonwovens will occupy an important position in the future nonwovens market. [0003] The existing spunbonded spunlace nonwovens have high breaking strength and tear strength, but the tensile deformation is still...
