Abstract

An integrally formed composition of foaming material and woven fibre cloth is produced through such steps as introducing the first woven fibre cloth through foaming agent to carry it on its both surfaces, covering the second woven fibre cloth on it to penetrate the foaming agent into the second one, heating to foam, roll pressing and cooling. Said the first woven fibre cloth is wrapped by foamed body and the one of surfaces has cloth appearance.

Description

Expanded material and fibre fabric integrally formed compound and method for making thereof

The present invention relates to chemical field, specifically, relate to a kind of thing and fibre fabric integrally formed compound and method for making thereof of foaming, is in order to make a kind of gas permeability material with cloth top layer and foaming thing top layer double grading.

The example that fibr tissue is used in combination with expanded material is existing a lot, for example shoe-pad, warming material etc., and known mode with foamed material binding fiber cloth all is to paste or the gummed mode is finished; As shown in Figure 1, with a fiber knit layer 11 and one expanded material 12 through gluing between rollers 13,14 guidings and both opposite faces after, after rolling wheel 15,16,17,18 pressurizations and heating, make fiber knit layer 11 and combine with expanded material 12, constitute combined type textile material 19.The applying of this kind foaming thing and fiber is often peeled off because of the applying poor effect, and a place peels off and then may cause full wafer or block to peel off, and causes result of use and aesthetic property all not good enough.Moreover known foaming thing knits interlayer mat stick with fiber or adhesive combines, and makes the gas permeability between its tissue interrupted, so air permeable effect is not good enough.

Main purpose of the present invention is to provide a kind of thing and fibre fabric integrally formed compound and method for making thereof of foaming, and making between its foaming thing and fiber weaving cloth is one-body molded the combination, constructs altogether and there is no separable interface between compound, and associativity is good, unexpected peeling off.

Of the present invention time a purpose is to provide a kind of thing and fibre fabric integrally formed compound and method for making thereof of foaming, and it constitutes compound and has good gas permeability, and surface touch is good, is suitable for as purposes such as warming clothing or permeable shoe pads.

For achieving the above object, foam thing and fibre fabric integrally formed compound principal character of the present invention is to comprise at least two fiber weaving cloths, wherein first fiber weaving cloth is by in the blowing agent groove, its surface is contained be soaked with blowing agent, fit mutually through the roller guiding with second fiber weaving cloth again, again by thermal treatment zone heating, make first cloth and ooze and second fiber weaving cloth in the blowing agent foaming and intumescing, because infiltrating in second fibrage foaming, part this blowing agent of mat is foamed combine one-body moldedly, promptly on this first fiber weaving cloth, lower surface all has suitable thickness foaming thing, second fiber weaving cloth then is positioned at the top layer, whole formation one four-layer structure thing, and it there is no obvious joint interface each other, structure commissure associativity is very firm each other, and its foaming thing and fiber are all kept original gas permeability.

For ease of understanding, enumerate a specific embodiment conjunction with figs. now, it is as follows to describe method of the present invention, principle and composite structure in detail:

Fig. 1 is known foaming thing and fiber weaving cloth associated methods schematic diagram.

Fig. 2 is the foam manufacturing flow chart of thing and fibre fabric integrally formed compound of the present invention.

Fig. 3 is the foam manufacturing process schematic diagram of thing and fibre fabric integrally formed compound of the present invention.

Fig. 4 is foam thing and a fibre fabric integrally formed compound part section stereogram of the present invention.

Fig. 5 is another embodiment of the present invention foaming thing and fibre fabric integrally formed manufacturing process schematic diagram.

See also Fig. 2, Fig. 3, according to the present invention foam thing and fibre fabric integrally formed compound, its manufacture process is described as follows:

At first comprise one first fiber weaving cloth 21, be weaving cotton cloth of proper width and continuous length, be generally the flat fabric that is made into through weft yarn, have gas permeability, 22,23,24,25 suitable guidings evenly attach on these first fiber weaving cloth, 21 surfaces the blowing agents 27 in this liquid bath 26 by a blowing agent liquid bath 26 through four rollers; Next comprises one second fiber weaving cloth 31, is the flat fabric of suitable thickness and density, has good sense of touch, via roller 32 guidings, merges with first fiber weaving cloth 21 of this impregnation blowing agent 27 and fits into a composite bed 35, through second wheel 33,34 escorts; The blowing agent that this composite bed 35 makes these first fiber weaving cloth, 21 upper and lower surfaces and part infiltrate second fiber weaving cloth 31 by a heater 36 foaming and intumescing that is heated becomes a suitable thickness foaming layer, that is this foaming layer coats this first cloth, 21 upper and lower surfaces on the one hand, the blowing agent that infiltrates in second fiber weaving cloth 31 also is subjected to heat foamable on the other hand, make this foaming layer 42 simultaneously with first, two fiber weaving cloths 21,31 one-body molded combining constitute a compound 40, this compound 40 is through a cooling device 51 cooling and shapings, at last by roller 52,53 roll and escort out, then finish rolling foaming thing and fibre fabric integrally formed compound 40.

As shown in Figure 4, this foaming thing and fibre fabric integrally formed compound 40 are a four-layer structure according to section, are foaming layer 41, one first fiber weaving cloths 42 in regular turn, foaming layer once 43 and one second fiber weaving cloth 44; This upper and lower foaming layer 41,43 is that one coats this first fiber weaving cloth 42, knitting layer 44 by this time foaming layer 43 and second fibrage again combines, as a complete unit, it is one (once) moulding, there is no the use adhesive, therefore, do not have the not good anxiety of gummed adherence, and layers of material all has suitable gas permeability, and overall structure also has good gas permeability.

This compound 40 is to provide suitable elasticity, warmth retention property or shock absorption by upper and lower foaming layer 41,43; Make its foaming layer 41,43 structure organizations have obdurability by this first fiber weaving cloth 42 again, promptly have the effect of enhanced foaming layer intensity; 44 fiber surfaces that good sense of touch and outward appearance are provided of this second fiber weaving cloth, therefore, this compound is suitable for using as article such as warming clothing, shoe-pads.

Again as shown in Figure 5, it is the method for making that one embodiment of the invention foaming thing and fiber are knitted the integrated compound of layer, it is identical substantially with the foregoing description, institute's difference be this first fiber weaving cloth 21 soak by blowing agent groove 26 contain blowing agent 27 after, will be by a blow-out nozzle 28, cloth cover volatilizees and form big open-work in mesh to utilize air blowing air pressure that the blowing agent that does not condense as yet in this cloth mesh is blown off, be merged into a composite bed 45 with second fiber weaving cloth 31 again, then by heater 36 heating one step foaming moulding one compound 50, then make to have big open-work on the compound of making 50, this is another preferable embodiments possible of the present invention.

Mandatory declaration be, the foregoing description accompanying drawing only is in order to explanation the present invention, and non-in order to restriction the present invention, it is feasible that other equivalence changes enforcement, for example this second fiber weaving cloth 31 is changed over to merge and fit, or heating, cooling device can wait in different ways by first fiber weaving cloth top.
