[0043] (1) Preparation of spunbonded fiber web

[0044] Add the spunbond raw material polypropylene and spunbond masterbatch to the two S-die heads according to the above ratio. The mixed and stirred raw materials are sucked into the screw extruder by vacuum suction through the feeding system, and extruded and melted under the condition that the melting temperature of the screw is 180°C-270°C to obtain a hot melt. Subsequently, under the condition of operating temperature of 230-250°C and pressure of 5-10MPa, the hot melt is filtered, metered and distributed through a filtration system and a metering pump. The distributed hot melt is sprayed out through a spinneret with a hole diameter of 0.3-0.8mm, and cooled by a side cooling system with a temperature of 10-20°C and a wind speed of 0.2-1.5m / s to obtain primary growth filaments. The method of air-flow splitting the primary growth filament, through the bell mouth of the drafter (narrow type), and drafting with the draft speed...

Embodiment 1

[0062] The composition of the spunbond masterbatch used in this embodiment is: 80 parts by weight of polypropylene, 19 parts by weight of fluoropolymer melt additive A, and 1 part by weight of lubricant. Wherein, the fluoropolymer melt additive A is polytetrafluoroethylene with an average molecular weight of 50,000-150,000.

[0063] The composition of the masterbatch for melt-blowing used in this embodiment is: 80 parts by weight of polypropylene, 19 parts by weight of fluoropolymer melt additive B, and 1 part by weight of lubricant. Among them, the fluoropolymer melt additive B is a copolymer of tetrafluoroethylene and perfluoromethyl vinyl ether, the ratio of tetrafluoroethylene and perfluoromethyl vinyl ether is 1:1, and the average molecular weight is 350000-450000, The molecular weight distribution is 2.

Abstract

The invention provides an SMS-type non-woven fabric manufacture method. The SMS-type non-woven fabric manufacture method comprises mixing, extruding and fusing, spinning, and splitting and lapping spunbond raw material polypropylene and spunbond master batch to obtain a spunbond layer fiber web; mixing, extruding and fusing, spinning and lapping meltblown raw material modified polypropylene and meltblown master batch to obtain a meltblown layer fiber web; taking the meltblown layer fiber web as the intermediate layer, and the spunbond layer fiber webs as the upper layer and the lower layer, and bonding the three layers of fiber webs in a hot pressing manner to obtain the SMS-type non-woven fabric. The invention also provides an SMS-type non-woven fabric prepared through the above method, and an application of the SMS-type non-woven fabric for preparing a disposable hygienic material. The SMS-type non-woven fabric is characterized by being excellent in blood repellent property, oil repellent property and alcohol repellent property.

Description

technical field [0001] The invention belongs to the technical field of non-woven fabrics, in particular, the invention relates to a method for manufacturing SMS-type non-woven fabrics, SMS-type non-woven fabrics obtained by the method and applications thereof. Background technique [0002] SMS type non-woven fabric (English: Spunbond+Meltblown+Spunbond Nonwovens) is a composite non-woven fabric, which is a composite product of spunbond and meltblown, with high strength, good filtration performance, no adhesive, non-toxic, etc. . At present, it is mainly used in medical and health labor protection products such as surgical gowns, surgical caps, protective clothing, hand washing clothes, handbags, etc. [0003] At present, the bottom film of sanitary napkins used by women mainly uses PE breathable film. However, PE film has poor air permeability, a sense of stuffiness, which affects the feeling of women's menstrual period, and is easy to cause problems such as gynecological ...
