Fibre synthetic plastic film and production method thereof

Abstract

The invention relates to a fiber synthesizing plastic film and production method, A) fiber net supplying procedure; B) film extrusion casting procedure: synthetic resin forms an extrusion casting film; C) thermal sealing procedure: an outlet of the fiber net supplying procedure is thermally sealed with the extrusion casting film in a melting state, with the casting film being extruded in the filmextrusion casting procedure; D) molding procedure: the plastic film with fiber adhered on the surface is thermally sealed in the thermal sealing procedure and is done with a corresponding molding method to form the plastic film with fiber adhered on the surface; E) wind up procedure: the synthesizing plastic film is wound up to become molding. The fiber nets of the production method utilize thin nets stuck naturally among fiber silk when the fiber is unfolded to be compounded with the plastic film in the melting state. The fiber nets can reduce the thickness of layering net and omit a cementing procedure or the thermal sealing procedure, thus effectively reducing gram weight formed by the fiber nets. The surface fiber of a compounding film compounded by the fiber nets and the synthesizingplastic film is soft with comfortable tactility and good for skin.

Description

technical field [0001] The invention relates to a production method of a film, in particular to a fiber synthetic plastic film and a production method thereof. Background technique [0002] With the improvement of people's living standards, in disposable sanitary products, especially disposable sanitary products such as women's sanitary napkins, sanitary pads, baby diapers, adult incontinence products, and medical mattresses, the use of dry mesh surfaces is increasing. Many, it is made of thermoplastic film through vacuum punching or mechanical punching. It has the advantages of fast infiltration speed and dry surface; but it also has the inherent plastic feeling and luster of the plastic film itself. It may cause discomfort to the user during use. [0003] In order to eliminate the plastic feeling of the plastic film, as shown in Figure 1, people compound the non-woven fabric with the synthetic plastic film to obtain a perforated film with a surface compounded with a non-w...

Problems solved by technology

[0003] In order to eliminate the plastic feel of plastic film, as shown in Figure 1, people compound non-woven fabrics with synthetic plastic films to obtain perforated surfaces of composite non-woven fabrics. Film, although the perforated film of this surface composite non-woven fabric can improve the touch of the film, but in the production of non-woven fabrics, in order to roll the fiber web into shape, the fiber web must be reinforced in an appropriate way, such as heat sealing Or gluing and other methods to bond and fix the fibers together, so that the fiber web has a certain mechanical strength, but it is precisely because the fibers are bonded and fixed together that the bulky and soft touch of the fibers is destroyed, so that the non-woven The feel of the cloth composite perforated film becomes hard, which offsets the improvement effect of the fiber on the surface feel of the synthetic plastic film, and is limited by the production of non-woven fabrics, and people cannot obtain low-weight non-woven fabrics such as less than 8 grams per square meter. , especially pure cotton non-woven fabrics, when the method of the present invention is used to produce, the required fiber web is heat-sealed with the synthetic resin film when it is output from the fiber web supply process, and the required fiber web does not need to be reinforced, so the fiber The grammage of the net can be lower, and even cotton fibers can be used as the fibers of the fiber web to form a plastic film with cotton fibers adhered to the surface
