DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transparent adhesive interlining and a method for producing the same.

[0002]

2. Description of the Related Art Conventionally, an adhesive interlining using a processing yarn has been popular as an adhesive interlining for a stretch woven or knitted fabric due to its excellent elasticity, and the mainstream is a semi-dal processing yarn in which titanium oxide or the like is blended with a polyester resin. Is used, and the processed yarn is set at a false twist number of about 4,350 turns / m and a set temperature of about 210 ° C.

For this reason, the conventional stretch woven or knitted adhesive interlining has not only a problem of losing transparency and a hard texture, but also causes interference fringes, that is, a moire phenomenon when it is adhered to a surface material. There were also problems.

[0004] In addition, the conventional stretch woven / knitted adhesive interlining is required to correspond to almost all colors of the surface material.
Color development of about 40 to 100 colors is required.

[0005]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the conventional stretch-woven and knit-bonded interlining, and has a soft texture and interference fringes when bonded to a surface material, that is, a moiré phenomenon. Low occurrence and required 4
It is an object of the present invention to provide an adhesive interlining that does not require color development of about 0 to 100 colors and can handle almost all colors of a surface material with color development of about 10 colors.

[0006]

In order to solve the above problems, in the invention of claim 1, an adhesive interlining is used as a polyester raw material, and a matting agent such as titanium oxide is used as a polyester raw material.
Polyester filament yarn fiberized by adding less than 10% by weight is represented by general formula 1

[Equation 1] ・ ・ ・ ・ ・ (1) And the set temperature is 170.
A heat-adhesive resin layer was formed on the surface of a woven or knitted fabric using a processed yarn that was set at a temperature of 200 ° C.

According to a second aspect of the present invention, a method for producing an adhesive interlining according to the first aspect is characterized in that a matting agent such as titanium oxide is added to a polyester raw material in an amount of 0.1% by weight or less of the polyester raw material to produce a fiber. General formula 1

[Equation 1] ・ ・ ・ ・ ・ (1) And the set temperature is 170-200 ° C.
Then, a woven and knitted fabric is formed by using the processed yarn, and then a heat-adhesive resin layer is formed on the surface thereof.

[0008]

The adhesive interlining according to the first aspect of the present invention has excellent transparency and flexibility, and conventionally has a color type of about 40 to 100 colors as an interlining in order to correspond to the color tone of the surface material. In contrast, in the case of the interlining according to the present invention, if about 10 color types are prepared, almost all surface materials can be handled.

According to the second aspect of the present invention, an adhesive interlining having excellent transparency and flexibility and easily heat-adhering can be obtained.

[0010]

EXAMPLE Twelve filaments of 30 denier obtained by adding 0.06% by weight of titanium oxide to a polyester raw material and melt-spinning were used to give a false twist of 3350 turns / m.
At a setting temperature of 190 ° C. to form a processed yarn, and woven in a plain weave structure.

The obtained plain woven fabric is subjected to relaxation processing and weight reduction processing, then dyed into 30 kinds of colors, and a polyamide-based thermo-adhesive resin is adhered to the surface thereof by a double dot method, so that the finishing density is reduced to 94. And an adhesive interlining of 64 wefts.

The amount of titanium oxide to be added as a matting agent to the polyester raw material is 0.
1% by weight or less, preferably 0.05% by weight or less.

The obtained polyester filament yarn is false-twisted at the number of false twists of the above-mentioned general formula 1, and heat-set at 170 to 200 ° C.

The number of false twists is the general formula 2

[Equation 2] · · · · (2) If the amount is less, there is a disadvantage that the unevenness on the surface of the fabric becomes intense after processing as a base fabric.

The number of false twists is represented by general formula 3.

[Equation 3] ・ ・ ・ ・ ・ (3) Above that, transparency is lost.

If the heat setting temperature is lower than 170 ° C., a sufficient setting effect cannot be obtained, and if it is higher than 200 ° C., the texture of the dough becomes hard.

As the structure of the interlining fabric, a woven fabric such as a plain weave, a twill weave, or a satin weave, or a knitted fabric such as a Russell knit or a tricot knit is used, but is not particularly limited.

These knitted and woven fabrics are subjected to processing such as relaxation processing, heat setting processing, weight reduction processing, dyeing processing, and finishing processing in the same manner as ordinary polyester processed yarn woven and knitted goods.

Next, a thermal adhesive resin is applied to the surface of the knitted fabric. Examples of the heat bonding resin include powdery polyamide-based resin, polyester-based resin, polyethylene-based resin, polyvinyl chloride-based resin, and polyolefin-based resin, and the coating amount is 1 to 20 g / m2.

As a means for applying the heat-adhesive resin, a powder of a heat-adhesive resin, which is a well-known ordinary heat-adhesive interlining application means, is sprinkled at random on a base cloth to be sieved, and then dispersed. Sintering method to fix heat, or
A spray method of spraying the heat-adhesive resin powder and the emulsion containing the powder from the nozzle onto the interlining base fabric using air and thermally fixing the same may be used. In addition, an embossing roll (a cup in which the adhesive resin enters in a dot form) may be used. Is filled with adhesive resin into a cup), and it is continuously transferred to the interlining fabric, and it is heat-fixed by a single dot method or a roll screen, and the emulsion is coated on the interlining fabric. Any means such as a double-dot method in which (a paste mainly containing an acrylic resin or a heat-bonding resin powder) is transferred in the form of dots, and a powder of the heat-bonding resin is sprayed thereon in a sieving manner and thermally fixed thereto.

The fewer the number of filaments of the polyester filament yarn used in the present invention, the better the transparency, but the less the number of filaments, the harder the texture. It is necessary to balance these.

[0022]

Comparative Example 1 A semi-dull yarn (30 denier / 12 filaments) produced by melt-spinning with adding 0.2% by weight of titanium oxide to a polyester raw material has a twist number of 4,350.
The number of times / m was set at a setting temperature of 210 ° C. to obtain a processed yarn.
Using this processed yarn, weaving was performed in a plain weave structure. Next, the plain woven fabric is subjected to relaxation processing and weight reduction processing, then dyed into 100 colors, and a polyamide-based thermo-adhesive resin is adhered to the surface of the plain woven fabric by a double dot method to give a finishing density of 94 strands, weft 64.
An adhesive interlining for a book was obtained.

[0023]

[Test] Adhesive core of the least inconspicuous color observed from the outer surface side on the back of 300 outer materials selected at random from all kinds of clothing such as thin polyester, wool, silk, cotton, polyester / wool The ground was selected and bonded from the bonded interlining obtained in the examples and comparative examples.

As a result, in the case of the adhesive interlining according to the embodiment of the present invention, only eight kinds, that is, eight colors of the interlining were used for the surface material of 300 points. In the case of the interlining, it was not possible to cope with it without using 68 kinds, ie, 68 colors of the interlining.

[0025]

According to the first aspect of the present invention, the twist number is smaller than that of the conventional twist number.
False twist with the fewest number of false twists
Extremely good set at 170-200 ° C below temperature
Weaving and knitting using a known process
Same as the processing of the product and the usual polyester processing yarn woven and knitted
Processed, polyamide resin, polyester resin, poly
Ethylene resin, polyvinyl chloride resin, polyolefin
Since the thermal adhesive resin such as resin is applied, the texture is soft and the transparency is excellent, so the interference fringes due to the interference of the number of threads when bonding to the surface material, that is, the moire phenomenon occurs. The effect can be reduced.

Further, by being transparent, there is an effect that the color type of the adhesive interlining used can be reduced to about 10 colors, corresponding to the color tone of the surface material of almost all colors.

According to the second aspect of the invention, there is an effect that the adhesive interlining according to the first aspect can be manufactured by a simple means of adjusting the amount of titanium oxide to be added, and adjusting the number of false twists and the setting temperature.

The number of false twists is equal to the number of false twists expressed by Formula 1.
When the false twist is performed with the number of false twists expressed by the general formula number 2
After processing as an interlining fabric, unevenness on the fabric surface becomes severe
It has drawbacks and is more than the number of false twists expressed by the general formula 1.
Transparency is achieved when false twisting is performed with the number of false twists expressed by general formula 3.
There is a drawback that is lost, but the number of false twists expressed by the general formula (1)
If it is false twisted, the unevenness of the fabric surface may become severe
And an effect that transparency is not lost.
Sufficient setting effect when the heat setting temperature is lower than 170 ° C
Is not obtained, and the texture of the dough becomes hard when the temperature is higher than 200 ° C.
Set at 170-200 ° C
Gives a sufficient set effect and the texture of the fabric
Has the effect of not becoming hard. That is, a processed yarn having extremely excellent transparency can be obtained by setting the number of false twists of the number 1 smaller than the conventional twist number, and setting the temperature at 170 to 200 ° C. lower than the conventional setting temperature. This processed yarn is processed by a known method in the same manner as the processing of a woven or knitted fabric and a normal polyester-processed yarn or woven or knitted fabric. Since the adhesive resin is applied, the adhesive interlining is provided with excellent transparency and stretchability and also excellent heat shrink resistance.
