The hot blast Nonwovens that uses the inventive method to produce has the following advantages:
1. flexibility: skin-friendly and comfort are arranged;
2. thickness is arranged: have more thick texture than general embossing Nonwovens;
3. good air permeability: be suitable for subtropical climate; And be different from general material, have sultry sensation during use;
4. permeability is good; Prevent to bleed back, allow going under the flow liquid, on do not come, effectively prevent to bleed back, keep dry and comfortable top layer, surface.
Below with reference to accompanying drawing, the present invention is further described, wherein:
Fig. 1 is that schematic flow sheet is made in a preferred embodiment of the present invention, includes two cycling hot wind wheels in the hot air apparatus.
Fig. 2 is a second embodiment of the invention, and the mode that adopts a plane to carry has only hot blast wheel.
Fig. 3 is a third embodiment of the invention, adopts hot air circulation about in the of.
The present invention is in the selection of fibrous raw material, the meldable fibre that comprises single composition, as polypropylene (PP), polyethylene (PE) fiber, or it is outer for low melting point composition internal layer is two composite fibres of forming of high-melting-point composition, as polypropylene (PP)/polyethylene (PE), polyethylene terephthalate (PET)/polypropylene (PP), nylon (Nylon) 66/ nylon (Nylon) 6, polyethylene terephthalate (PET)/polyamide fiber fibers such as (COPET).
The present invention also can be with the demand of product performance with low melting point meldable fibre and other fiber such as artificial fibre (Rayon), polyethylene terephthalate (PET), nylon (Nylon), paper pulp (Pulp), mix in proportion and mutually and use.
As shown in Figure 1, handling process of the present invention is through the moulding of the combing effect of carding machine 2 or specially-shaped machine and make fiber web 3 with fibrous raw material 1, this fiber web will further be sent in the hot air apparatus 4, so that the hot blast of hot air apparatus 4 penetrates, low-melting fiber in the fiber web 3, the effect of heated air and blast, make the low melting point composition fusion of meldable fibre surface, between fiber and fiber thereby stick together mutually, form a non-woven with high loft, high strength, softness, through after this treatment step, promptly form hot blast Nonwovens 5 of the present invention.At last, this hot blast Nonwovens 5 is batched rolling through coiling machine 6.
