SPECIFICATION
A method for treating synthetic fiber or high molecular substance by heating BACKGROUND OF THE INVENTION 5
This invention relates to a method for treating synthetic fiber or high molecular substance by heating. More particularly, this invention relates to a heating method required in processing fabric, sheet, or film composed of synthetic fiber or high molecular substance (1) to make soft and then press-mold or transform, (2) to make knitted or weaved tissue tight and close by shrinking overall, (3) to make figured with crimping-pattern or embossing- pattern by shrinking 10 partially, (4) to cut or make holes by melting partially, and (5) to set the fabric or stabilize the form by welding the composing synthetic fiber.
This invention also relates to a heating method required in processing to weld powdered materials composed of synthetic resin or high molecular substance on the surface of necessary base materials, still more to make foamy powdered materials and sheet or coating film which 15 were composed of synthetic resin or high molecular substance containing foaming-agent.
In the former technique, in the case of heat welding of thermo weld synthetic fiber or high molecular substance such as hot melt synthetic fiber or hot melt powdered resin (powdered coating paint etc.) to fabric, sheet and other base -materials, those base materials were also heated to more than the melting point of thermo weld synthetic fiber or high molecular sub- 20 stance.
Therefore, according to this conventional method, when the base materials are very thin and when they are composed of synthetic fiber or high molecular substance, which has a little higher melting point than thermo weld synthetic fiber or high molecular substance, those thermo weld synthetic fiber or high molecular substance could not be welded to the base materials. Further 25 more, in putting embossing-pattern on the surface of fabric composed of synthetic fiber by pressing heated embossing roll, in order to sharpen the edge of pattern the embossing roll must be heated higher and be pressed more strongly, but such high temperature and strong pressure cause a formation of film or breakage on the spot.
Especially, in case of fabric of thin make, the whole fabric is easy to shrink and transform by 30 thermal radiation from embossing roll.
Thus, it was very difficult to put on embossing-pattern on the surface of fabric.
SUMMARY OF THE INVENTION
The first object of this invention is to heat only synthetic fiber or high molecular substance to 35 be welded or only the spot to be transformed, in the case of heatwelding thermo weld synthetic fiber or high molecular substance to necessary base materials, and in the case of heating and transforming a part of fabric and sheet etc. composed of synthetic fiber or high molecular substance.
The second object of this invention is to prevent heating the unnecessary part and causing 40 unfavorable transformation in such heat processing.
The third object of this invention is to control the degree of heat in order not to cause unfavorable transformation on the spot of synthetic fiber or high molecular substance to be heated in such heat processing.
In this invention, to fulfil the above objects, synthetic fiber or high molecular substance is 45 treated or prepared with steps to intervene the material, which far more absorbs electromagnetic waves and generates heat than synthetic fiber or high molecular substance, in or on or near the surface of synthetic fiber or high molecular substance, subsequently to set the synthetic fiber or high molecular substance under electromagnetic waves until that intervened material grows hotter and generates heat, and to heat up synthetic fiber or high molecular substance to soften, shrink, 50 melt, weld, or melt-break through that intervened material by electromagnetic waves.
To obtain best results, near infrared radiation is applied as electromagnetic wave. And, graphite and carbonblack or other black body substance is applied as the material to be intervened.
Synthetic fiber or high molecular substance may be applied by forming the fabric such as seat 55 top layer, seat covering, wall covering, carpet, curtain, clothing and the like.

DETAILED DESCRIPTION
This invention was completed on the basis of the following knowledge. 5 That is, electromagnetic wave has a function to heat up materials, and the degree of heating up differs according to materials. And, there are materials which are heated up to far higher temperature than synthetic fiber or high molecular substance. And, among those materials which are easily heated up, there are some which could be heated up to far higher temperature by the electromagnetic waves which exist in the special wavelength band. 10 Such materials that absorb more electromagnetic waves and heat up higher than synthetic fiber or high molecular substance henceforth called "exothermic-sensitive-substance".
An electromagnetic waves which heat up such exothermic-sensitivesubstance, near infrared radiation is applied.
This near infrared radiation is one kind of electromagnetic wave which exists in the wavelength 15 band of 720-1500mli. To practice this invention more effectively, it is preferable to apply the near infrared radiation of which main wavelength is about 750my and which is nearer to the visible light.
As to near infrared radiation, which is applied in this invention, is explaned as follows; That is, infrared radiation should exist in from 1011 Hz to 4 x 1014 Hz frequency band, having a 20 wide wavelength of 0.72,u-1000,u between visible light and microwave, and that in the wave length band of 0.72ji-1.5y is called near infrared radiation, that in the band of 1.5,U-5.6,u is called ordinary (middle) infrared radiation, and that in the band of 5. 6/L-1000/t is called far infrared radiation. According to this distinction, near infrared radiation lamps, middle infrared radiation lamps and far infrared' radiation lamps are sold in the market. 25 While in this invention the lamp which emits near infrared radiation of 0. 72 U-1.5,u is used, it is recommended especially that near infrared radiation lamp, of which main wavelength is about 0.751t, irradiates from within 10cm.
Graphite and carbonblack used as exothermic-sensitive-substance in this invention are black materials. But all of black or dark materials are not necessarily applied in this invention as 30 exothermic-sensitive-substance. In other words, the term "To intervene exothermic-sensitive substance in the interior and on the surface or near the surface of synthetic fiber or high molecular substance" does not mean "To make the color of synthetic fiber or high molecular substance black or dark".
Thus, in the case of irradiation near infrared radiation from within 10cm, exothermic-sensitive- 35 substance may be used in the measure that it does not make the color of synthetic fiber or high molecular substance black or dark, namely intervening under 0.1% by weight exothermic-sensi tive-substance in the interior or on the surface or near the surface of synthetic fiber or high molecular substance.
Therefore as long as it has not been colored by exotherm ic-sensitivesubsta nee but by 40 pigment or dyestuff,. even though it has been colored in black or dark, synthetic fiber or high molecular substance could be partially heated by near infrared radiation to make partially soften, shrink, melt, weld, or melt break, only when exothermic-sensitivesubstance has Peen intervened therein.
Incidentally, whether graphite and carbonblack or other black body substance come under 45 exothermic-sensitive-substance or not, it is easily confirmed by irradiation of near infrared radia tion.
Synthetic fiber or high molecular substance as applied in this invention are thermo plastic synthetic fiber such as nylon, acrylic fiber, polyester fiber, vinylon etc. and synthetic resin of the same composition as the above synthetic fibers. 50 Samples of form of intervention of exothermic-sensitive-substance in the interior or on the surface or near the surface of synthetic fiber or high molecular substance are as follows.
(1) To spin synthetic fiber by mixing exothermic-sensitive-substance in high molecule sub stance or synthetic resin which composes synthetic fiber.
(2) To coat or attach exothermic-sensitive-substance onto the surface of synthetic fiber to- 55 gether with binder.
(3) To make spun yarn by blending ordinary synthetic fiber with special synthetic fiber which contains exothermic-sensitive-substance or was coated or attached with exothermic-sensitive substance.
(4) To make double yarn or twist yarn with yarn which contains exothermicsensitive-sub- 60 stance and yarn which is composed partially or wholly of ordinary synthetic fiber, (5) To the surface of yarn which is composed partially or wholly of ordinary synthetic fiber, suitably with binder to spray or stick or coat a powder of exothermic- sensitive-substance or a powder which contains exothermic-sensitive-substance.
(6) To make synthetic resin powder, sheet or to form coated film with high molecular 65 3 GB2193147A 3 substance which contains exothermic-sensitive-substance.
(7) To the surface of ordinary synthetic resin sheet or coated film, suitably with binder to spray or stick or coat a powder of exothermic-sensitive-substance or a powder which contains exothermic-sensitive-substance.
When synthetic fiber or high molecular substance is heated by near infrared radiation through 5 the exothermic-sensitive-substance, the degree of these transformations, softening, shrinking, melting, welding, or melt-breaking, can be controled by the following factors.
(a) Amount of near infrared radiation (distance between irradiation lamp and synthetic fiber or high molecular substance and irradiation time).
(b) Amount of exothermic-senstive-substance to intervene synthetic fiber or high molecular 10 substance.
(c) Existance of material retarding heat transformation (hence for the called transform-retardance) in intervention.
(d) Existance of material promoting heat transformation (hence for the called transform-pro- moter) in intervention. 15 (e) Volume of these materials. (transform-retardance, transform-promoter) As transform-retardance the following materials are used.
(a) Aluminum hydroxide etc as flame-resistance.
(b) Silicone rubber and other reactive silicone resin etc as meltresistance.
(c) Diazocarbonamid etc as foaming-agent. 20 It is effectively to use these transform-retardances, especially reactive silicone resin as melt resistance, when it is desired to cause heat-shrink of synthetic fiber without reducing degree of crystallization of high polymer and to retain necessary tensile strength for synthetic fiber after shrinking.
Reactive silicone resins applied to this object are: dimethyl-polysiloxane methyl-hydrogen-poly- 25 siloxane epoxy-modified-dimethyl-poly-siloxane amin- mod ified-poly- siloxane etc.
As transform-promoter-alkalic and acidic opal-finish-agents are used.
These agents corrode synthetic fiber or high molecular substance, just as caustic soda cor rodes polyester fiber. Use of these transform-promoters will produce a good result when syn- thetic fiber is heat-melted and breaken. 30 Synthetic fiber or high molecular substance to which this invention is applied, may be yarn, fabric, pile and fluff on the surface of fabric, sheet or film and others that form the surface layer of other base materials.
In conclusion, effects of this invention are summarized as follows:
(1) Fabric and sheet composed of synthetic fiber or high molecular substance are not heated 35 directly by heating apparatus but heated indirectly through intervening exothermic-sensitive-sub stance.
Therefore, the part of synthetic fiber or high molecular substance that is not intervened by exothermic-sensitive-substance is not heated and thus neither shrink nor melt in the same way as the part that is intervened by exothermic-sensitive-substance. 40 (2) Exothermic-sepsitive-substance can be made to intervene to very closely limited part.
Therefore, this heating can be applied to closely limited part of fabric and sheet composed of synthetic fiber or high molecular substance.
Accordingly, very Ihin fabric and sheet can be heated partially.
And by this partial ' heating and shrinking it becomes possible to draw crimping-pattern and 45 embossing-pattern on very thin fabric and sheet.
(3) Customary printing machine can be used to intervene exothermicsensitive-substance de picting pattern on fabric iind sheet composed of synthetic fiber or high molecular substance.
Therefore, using printing machine it is possible to make more colorful those various patterns such as crimping-pattern in following Example 1, embossing-pattern in following Example 2 and 50 see-through-pattern in following Example 6 by coloring with dyestuff and pigment the circumfer ence of pattern depicted by exothermic-sensitive-substance.
Thus, in way of design, up-to-date fabric and sheet can be produced.
(4) Carboriblack and graphite used as exothermic-sensitive-substance could be heated up to so high temperature as to soften, shrink, melt, weld or melt-break synthetic fiber or high 55 molecular substance, only when near infrared radiation is irradiated strongly from very short distance.
However, carboriblack and graphite can not be heated to so high temperature as to transform synthetic fiber or high molecular substance by small amount of near infrared radiation contained in ordinary sun-shine or illumination lamp. 60 Therefore, synthetic fiber or high molecular substance processed by this invention does not bring hindrance to practical use because of its containing exothermic- sensitive-substance.
Further in necessary case, after irradiation of near infrared radiation exothermic-sensitive substance can be removed by washing, if it is used together with water soluble Pinder in intervening to synthetic fiber or high molecular substance. 65 4 GB2193147A 4 The following is concrete explanation of this invention by example.
EXAMPLE 1
Paint was prepared by mixing the following components.
Algin-acid-natrium 2 parts by weight 5 Graphite powder I part by weight Silicone -rubber emulsion I part by weight 10 Water e.......... 96 parts by weight This paint was printed on plain weave fabric (200g/M2) of polyester fiber by auto-screen printing machine. Then, after paint film has been dried, the fabric was translated at the speed of 15 7 m/minute to pass through the portion which was 50 mm distant from near infrared radiation tube-type lamp, of which out put power was 10kw/m, which emits near infrared radiation of which main wavelength was about 750my, and graphite printed spot was exposed to near infrared radiation during passing time.
As results, only the spot, where graphite was printed, shrink and rose to form crimping- 20 pattern. Thus, the fabric that is suitable for curtain was obtained.
Figure 1 is twice enlarged photograph of the fabric thus obtained.
Figure 2 is 80 times enlarged. microscope photograph of the borderline between the two parts of the fabric, painted and not painted.
25 EXAMPLE 2
Paint was prepared by mixing the following components, Acrylic resin emulsion (40% sol id) 35 parts by weight 30 Mineral turpentine 33 parts by weight Carbonblack "...... 0.5parts by weight Water 31.5parts by weight 35 This paint was printed on the raised surface of the raising fabric which was woven with polyester fiber and raised (weight of raised layer 45 g/M2) by auto- screen printing machine.
Then, after paint film has been dried, the fabric was treated at the speed of 5 m/minute as in Example 1, and carbonblack printed spot was exposed to near infrared radiation. 40 As results, only the raising fluff painted with carbonblack melted, shrunk and welded to base of the raising fabric, forming concave part on the raising surface. While the raising fluff that was not painted with carbonblack remained as it was and formed convex part. Thus, the fabric which has sharp embossing-pattern on the raising surface and which is suitable for seatcovering was obtained. 45 Fig. 3 is three times enlarged photograph of the fabric thus obtained.
Fig. 4 is 80 times enlarged microscope photograph of the borderline between the two parts of the fabric, painted and nbt painted.
EXAMPLE 3 50
Coarse fabric (20Q g/M2 by weight) was woven with No.20 count spun yarn as warp and weft which was spun with blending, at the ratio 4:1 by weight, ordinary 10 denier polyester fiber and 7 denier rayon fiber spun by mixing 3% (by weight) carbonblack. Then, the fabric was treated at the speed of 6 m/minute as in Example 1, and the fabric was exposed to near infrared radiation.
As results, the polyester fiber was welded through the intervention of rayon fiber. Thus, the 55 fabric was finished up to be close in texture and very good in stability as if it was finished with resin infiltrated.
EXAMPLE 4
As the ground yarn using No.20 count span yarn which was used in Example 3, and as the 60 pile yarn using 500 denier nylon multi-filament yarn, plain moquette_of 5 mm pile length was woven. Then, in order to expose the back surface of this moquette to near infrared radiation, this moquette was treated at the speed of 6 m/minute as in Example 1.
As results, on the back surface of this moquette, between the polyester fibers of ground yarn and between the nylon multi-filament fibers of backstich of pile, these fibers welded each other, 65 1 GB2193147A 5 and this moquette was finished as if backing emulsion compound was coated on it's back surface.
Fig. 5 is 9 times enlarged photograph of the back surface of moquette thus obtained.
Fig. 6 is 9 times enlarged photograph of the back surface of the same moquette before being processed by this invention. 5 EXAMPLE 5
Polyethylen resin powder of 100ju diameter, in which 3% (by weight) carbonblack was mixed, was scattered evenly (about 250 g/M2) on the back surface of moquette which has been heated preparatorily by going through atmospherc heatzone of 14WC. Then, in order to expose polye- 10 thylen resin powder scattered on the back surface of moquette to near infrared radiation, this moquette was treated as in Example 1. Immediately after irradiating this near infrared radiation, the back surface on which polyethylen resin powder has been scattered was pressed by press roll.
As results, film of polyethylen resin stuck to the back surface of moquette. Thus, the 15 moquette was finished firmly being given good form stability.
EXAMPLE 6
On the surface of double texture tricot (100 9/M2 by weight), which was knitted to form double texture with face-texture and back-texture with 5 denier polyester filament yarn, pattern 20 was drawn by pencil in about 2 mm thick line and thus graphite of pencil lead was stuck. Then, to irradiate near infrared radiation on the surface, on which pattern was drawn, this tricot was treated at the speed of 6 m/minute as in Example 1.
As results, the part of polyester filament yarn of face-texture that was stuck with graphite melt-broke and the melted material was drawn and fixed firrily to the part of face-texture that 25 was not stuck with graphite and did not melt, and from the broken spot appeared polyester filament yarn of back-texture, thereby as the broken spot became thin, and the pattern drawn previously in pencil line turned into a see-through-pattern.
Fig. 7 is 5 times enlarged photograph of the tricot thus obtained. In the photograph, there are two parallel white lines depicted by dyeing, and dots depicted in white show the portions melt- 30 broken.
Fig. 8 is 40 times enlarged microscope photograph of melt-broken portion of Fig. 7.
Claims (5)
1. A method of treating a material of synthetic fibre or high molecular substance by heating, 35 which comprises treating said material at or adjacent a surface thereof with a second substance which absorbs electromagnetic waves and generates heat to a greater extent than said synthetic fibre or high molecular substance, and subjecting said treated material to electromagnetic radia tion to cause heating of said second substance and subsequently heating of said material by said second substance to shrink, soften or melt said synthetic fibre or high molecular substance, 40
2. A method for treating synthetic fibre or high molecular substance by heating which comprises; intervening graphite or carbonblack or other black body substance in the interior or on the surface or near the surface of synthetic fibre or high molecular substance, irradiating near infrared radiation to said synthetic fibre or high molecular substance until said graphite or carbonblack or other black body substance grow hotter, thereby heating said synthetic fibre or 45 high molecular substance through said intervened graphite or carbonblack or other black body substance until said synthetic fibre or high molecular substance soften, shrink, melt, weld or melt-break.
3. The method according to claim 1 or claim 2 wherein the near infrared radiation is electromagnetic wave which exists in the wavelength band of 0.72,U-1.5,U, and main wavelength 50 of which is about 0.75M (750mp), and in or on or near the surface of synthetic fibre or high molecular substance the powdered graphite and carbonblack or other black body substance intervenes under 0.1% by weight.
4. The method according to claim 3 wherein the synthetic fibre or high molecular substance is applied in fabric such as seat top layer, seat covering, wall covering, carpet, curtain, clothing 55 and the like.
5. A method according to claim 1 of treating a material of synthetic fibre or high molecular substance substantially as hereinbefore described.
