Problems solved by technology

[0003] Although the softening formula currently used in the industry can improve the softness of the product to a certain extent, the softness is limited. In addition, it is a problem that the industry cannot solve at the same time to take into account the strength, softness, smoothness and stable batch production of the product.

Embodiment Construction

[0026] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0027] Supersoft SS non-woven fabric of the present invention, its production process is as follows:

[0028] 1. The raw materials and functional masterbatches are configured into raw and auxiliary materials according to the following weight ratio:

[0029] Weight ratio of polypropylene: elastomer: softener: cooling masterbatch: 55-90:5-40:1-4:0.5-1.

[0030] Wherein, the polypropylene adopts the polypropylene of Mobil Exxon Company, such as the polypropylene whose product model is polypropylene 3155 (ExxonMobil polypropylene 3155),

Abstract

The invention discloses super-soft SS (spunbond and spunbond) nonwoven fabric. The super-soft SS nonwoven fabric is mainly made from, by weight, 55-90 parts of polypropylene, 5-40 parts of elastomer, 1-4 parts of softener and 0.5-1 part of cooling masterbatch. The invention further discloses a production process of the super-soft SS nonwoven fabric. The production process includes the steps of preparing raw materials and auxiliary materials according to the proportion, mixing well, melt-compressing by a screw extruder to obtain viscous flow melt, sending the melt into a melt filter for filtration, allowing the melt to enter a spinning die head, allowing trickle of the melt to be extruded out of spinneret orifices, allowing a drafting air channel to draft and shape the trickle of the melt under the action of process cooling air so as to obtain fiber of certain strength, allowing the fiber to be evenly adsorbed to a forming conveyor belt by a diffusion air channel to form a continuous mesh fiber layer, and rolling the fiber mesh into the nonwoven fabric of certain longitudinal and transverse tension by a hot rolling mill. The SS nonwoven fabric produced according to the formula by the process is smaller than 1.5g in softness, and is as soft and smooth as silk to touch and highly suitable for shell fabrics of baby diapers.

Description

technical field [0001] The invention relates to a SS nonwoven fabric, in particular to a formula and a production process of the SS nonwoven fabric. Background technique [0002] As a disposable fabric, spunbonded nonwoven fabrics have been more and more widely used in baby diaper fabrics in recent years. With the improvement of people's living standards, consumers have higher and higher requirements for the fabrics of baby diapers. The spun-bonded non-woven fabric produced by traditional technology has poor softness and stiff hand feeling, which can no longer meet the soft and comfortable requirements of baby diapers. How to improve the softness of spunbonded nonwoven fabrics, how to improve the softness of spunbonded nonwoven fabrics to the level of silky softness, has become a common technical problem encountered in the nonwoven fabric industry. [0003] Although the softening formula currently used in the industry can improve the softness of the product to a certain ex...
