Description

TECHNICAL FIELD The present invention relates to a reinforcing material used as a substitute for an interlining material or the like in order to impart shape retention, dimensional stability and the like to clothes.

[Prior Art] Conventionally, interlining is used for the collar, shoulders, chest, front body of clothes, etc. in order to keep clothes in a shape that matches the shape of the body and maintain a beautiful silhouette. Adhesive interlining was widely used because of its goodness.

However, the interlining has problems such as increasing the weight of clothes, hardening the texture, and the color of the part where the interlining is used is slightly different from other parts. If you wear it because it behaves differently than the movement of the outer material, or if it is affected by moisture or heat due to cleaning etc., the outer material may be warped or wavy due to the difference in contraction rate etc. There was also a problem caused by the structural difference between the outer material and the inner material, that is, it was put up.

In order to solve these problems, it has been considered to provide the outer material with desired shape retention and dimensional stability without using an interlining material, and a method for manufacturing clothes in which a resin is directly attached to a necessary portion of the outer material. Was proposed (JP-A-58-23911). However, this method requires a device that coats the resin in an appropriate arrangement, so it is not possible to easily process the resin at each sewing site. Since the resin adhesion position is different, it is difficult to change the setting of the coating device correspondingly, which is a practical problem.

[Problems to be Solved by the Invention] The present invention has been made to solve the above-mentioned drawbacks of the prior art, and a reinforcement capable of arranging a resin on a desired portion of a dress material by a simple operation at a sewing site. Regarding materials

[Means for Solving the Problems] The present invention provides a release sheet having an upper layer made of a heat-adhesive resin and a lower layer having a melting point of 60 ° C. or higher than the heat-adhesive resin, or a thermosetting resin. The present invention relates to a reinforcing material in which a resin having a two-layer structure made of (hereinafter referred to as "non-heat adhesive resin") is discontinuously distributed.

[Operation] That is, the reinforcing material of the present invention is laminated at a desired position on the outer material in an appropriate size, and the heat-adhesive resin in the upper layer is melted by applying heat or pressure with an iron or a press. The resin having a two-layer structure discontinuously distributed is arranged on the outer material by adhering it to the outer material and then peeling off the release sheet. Thus, in the portion where the resin having the two-layer structure is arranged, appropriate rigidity and dimensional stability can be obtained, and as a result, excellent shape retention can be obtained without using an interlining.
Further, since the resin on the lower layer side of the reinforcing material is made of a resin having a melting point of 60 ° C. or more higher than that of the thermosetting resin of the upper layer, or a thermosetting resin, it is subjected to heat and pressure after being placed on the outer material. However, it is not affected, and the heat-adhesive resin sandwiched between the outer material and the outer material does not re-adhere to an unnecessary portion such as the lining.

[Examples] The present invention will be described in more detail below with reference to the drawings.

As shown in FIG. 1, the reinforcing material of the present invention is a resin having a two-layer structure in which an upper layer is made of a heat-adhesive resin 3 and a lower layer is made of a non-heat-adhesive resin 2 on a release sheet 1. Has a discontinuously distributed structure.

The releasable sheet 1 has a resin layer 2 and a resin layer 3 which are laminated so that the reinforcing material can be quickly peeled off after adhering the reinforcing material to a surface material.
A release paper or a release film having releasability is used.

As the thermo-adhesive resin 3, a resin that can bond a reinforcing material to a material to be reinforced by heat treatment is used. When using a reinforcing material for clothing, when subjected to heat treatment with an iron, a press or the like, those exhibiting thermal adhesiveness are used, for example, a polyamide resin having a melting point of 90 to 125 ° C., a polyester resin, A thermoplastic resin such as polyethylene resin is preferably used.

Further, as the non-thermoadhesive resin 2, a resin that does not exhibit an adhesion behavior when the upper thermoadhesive resin 3 is melted and thermally adhered is used. Therefore, as the non-heat-adhesive resin 2, a resin having a melting point higher than that of the heat-adhesive resin 3 by 60 ° C. or a thermosetting resin is used. For example, a polyamide resin or a polyester resin having a melting point of 150 to 250 ° C. In addition to thermoplastic resins such as, thermosetting resins such as self-crosslinking polyacrylic acid ester copolymers and melamine resins are preferably used.

In the reinforcing material of the present invention, the thermal adhesive resin 3 is
It is laminated so as to be placed on the table of the non-heat-adhesive resin 2, and has a two-layer structure of the heat-adhesive resin 3 as the upper layer and the non-heat-adhesive resin 2 as the lower layer. The resins 2 and 3 having the two-layer structure are
For example, as shown in FIG. 2, on the releasable sheet 1, the predetermined shapes such as circles (a), squares (b), and lines (c) are discontinuously distributed in an appropriate arrangement. It is provided in. The reason why the resin is discontinuously arranged in this way is that the resin does not harden the texture of the surface material more than necessary when the resin is attached to the surface material. The shape and arrangement of the resin that adheres greatly affects the texture of the outer material. For example, if the circles in (a) of FIG. It shows shape, and (b) shows slightly strong rigidity in the lateral direction, and in the case of a linear shape like (c), it has rigidity in the direction of the line, and there is tension or waist in this direction. can get.

Further, the ratio of the area of the resin, particularly the area of the non-heat-adhesive resin 2 occupying the releasable sheet, also has a great influence on the surface material when attached to the surface material. Generally, if the ratio of this area exceeds 60%, the texture becomes too hard to be practically used.
If it is less than%, it becomes impossible to impart appropriate rigidity and shape retention to the outer material. Particularly desirable area ratio is 10 to 50
%.

As a method for disposing the non-thermoadhesive resin 2 and the thermoadhesive resin 3 on the releasable sheet 1, a known resin printing method,
For example, by printing resin with a screen roll, after printing the non-thermoadhesive resin, so as to synchronize with this, a method of printing the thermoadhesive resin, or a roll having a recess corresponding to the arrangement of the resin to be attached, There is a method in which the heat-adhesive resin and the non-heat-adhesive resin are preliminarily laminated and filled in the concave portion, and then transferred to a release sheet. However, considering the ease of production, it is particularly preferable to print the non-thermoadhesive resin and then spray the thermoadhesive resin powder in a state in which the non-thermoadhesive resin has tackiness.
In this case, powder that has fallen outside the non-heat-adhesive resin printed area can be easily removed by brushing it off.
The thermo-adhesive resin can be accurately laminated on the non-thermo-adhesive resin without any technical difficulty.

The reinforcing material of the present invention thus obtained, as shown in FIG. 3, is laminated with a cloth to be reinforced such as the outer material 4,
Heat-bonded resin 3 by heat treatment with iron, press machine, etc.
Are integrated by melting. Then, the releasable sheet 1 is peeled off from this integrated body to obtain the one in which the non-heat-adhesive resin 2 is attached to the outer material 4 via the heat-adhesive resin 3.

FIG. 4 is an example showing a portion 5 to which the above resin is attached to the outer material 4 when manufacturing clothes. Since the reinforcing material of the present invention has a structure in which a resin having a two-layer structure is arranged on a release sheet, it is possible to select a reinforcing material having a resin arrangement suitable for each portion, and further, a portion to which the resin should be attached. It can be easily applied to each part by cutting according to the shape of. Therefore, a special device for adhering the resin or a special operation is not required, and it can be used for sewing by a simple handling similar to the conventional adhesive interlining.

Further, at the resin-attached portion 5 on the outer material, the heat-adhesive resin 3
Since the non-heat-adhesive resin 2 is attached through the structure, the non-heat-adhesive resin 2 is still attached to the non-heat-adhesive resin 2 even after a heat treatment step in which the heat-adhesive resin exhibits adhesiveness in the subsequent sewing work. Therefore, it does not contaminate other parts such as the lining.

In order to secure such an effect, it is desirable that the resin is attached such that the area of the non-thermoadhesive resin 2 is larger than the area of the thermoadhesive resin 3.

(Example 1) An emulsion of a self-crosslinking polyacrylic acid ester resin (100 blowing of ethyl acrylate, a copolymer of 2 mol% of N-methylolacrylamide and 2 mol% of acrylic acid) was applied onto a release paper as shown in FIG. A pattern (a) (however, the diameter of the circle was 0.3 mm and the number of circles was 196 / cm ² ) was printed so that the solid content deposition amount was 5 g / m ^2, and dried. Then, on the release paper, while the resin has adhesiveness, hot-melt type polyamide powder (melting point: 110 ° C., particle size: 60 to 200 μm) is sprinkled, and the surplus is removed by 5 g / m ^{2 was} deposited on the above resin. After this, the temperature is 150 ℃
Was heat-treated for 3 minutes to self-crosslink the resin and fix the polyamide powder on the resin to obtain a reinforcing material.

Cut the obtained reinforcing material so that it fits the cuff part of the cotton broad blouse, and laminate at this part and 150 ℃
When processed with an iron, it was able to give the cuffs proper tension and waist, and was excellent in shape retention.

Similarly, when the reinforcing material was applied to the front part of the cotton tricot shirt, it was possible to provide a proper amount of tension and waist and suppress the elongation at this part.

(Example 2) As the heat-adhesive resin, hot-melt type polyester powder (melting point: 105 ° C, particle size: 60 to 200 µm) was used, and the adhesion amount was adjusted.
A reinforcing material was prepared in the same manner as in Example 1 except that the amount was 12 g / m ² .

When the obtained reinforcing material was applied to the collar of a broad shirt of polyester / cotton = 55/45, it was possible to impart appropriate tension and shape retention.

(Example 3) The print pattern of the self-crosslinking polyacrylic acid ester resin emulsion was set to a pattern as shown in FIG. 2 (b) (ratio of print area to release paper: 20%), and hot Adhesion amount of melt type polyamide powder is 15g /
A reinforcing material was prepared in the same manner as in Example 1 except that m ² was used.

When the obtained reinforcing material was applied to the front body part of a wool 100% woolen jacket, excellent shape retention was obtained, and lateral tension and waist required for the chest were obtained.

[Advantages of the Invention] The reinforcing material of the present invention comprises, on the release paper, an upper layer made of a thermoadhesive resin and a lower layer made of a resin having a melting point of 60 ° C. or higher than the thermoadhesive resin, or a thermosetting resin. Since the resin having a two-layer structure is discontinuously distributed, the following effects can be obtained.

By cutting the reinforcing material according to the shape of the reinforcing portion, it can be applied to various reinforcing portions.

By heat-treating with an iron, pressing machine, etc. and peeling off the release sheet, the resin can be attached to the material to be reinforced such as outer material, so it can be easily processed at the sewing site without using special technology or equipment. be able to.

When the resin adheres to the outer material, etc., the non-heat-adhesive resin adheres via the heat-adhesive resin, so even if heat is applied in the subsequent sewing work, the heat-adhesive resin will not It does not adhere or become contaminated with

By discontinuously adhering the resin, it is possible to impart good dimensional stability and shape retention without hardening the feel of the body to be reinforced such as the outer material.

By changing the amount of the resin to be attached and the shape of the resin to be attached, the body to be reinforced such as the outer material can be given tension or waist according to the site.

When using it for clothing, like when using adhesive interlining,
There are no problems such as a large increase in weight, hardening of the texture, color blurring, and deformation of clothes due to the difference in behavior between the outer material and the inner material.

As described above, the reinforcing body of the present invention has excellent effects,
Particularly, it is extremely suitable for use as a substitute for an adhesive interlining material in the production of clothes and the like.
