[Detailed description of the invention] (Technical field to which the invention pertains) It is well known that before sewing women's and men's clothing, an adhesive interlining is bonded to the back side of the fabric by applying heat and mechanical pressure. . The present invention relates to a method for increasing the adhesive strength, that is, the peel strength, of an adhesive core in thermal bonding between the adhesive core and a fabric.

(Prior Art) Fabrics for women's clothing are often thin, and therefore the adhesive interlining (also referred to as interlining) used in combination therewith is also thin. Men's clothing fabrics are thicker than this, for example α4~α.
Some are 55m long. In either case, the adhesive core is required to have high adhesion to the fabric and high tensile strength. The material of the adhesive core may be non-woven fabric, or it may be made of coarsely woven 100-inch cotton, twisted yarn of cotton and polyester, or mixed yarn of polyester, rayon, etc., but both have good air permeability. In addition, the adhesive used for bonding is often a polyamide-based or polyester-based hot melt adhesive that melts when heated, and is spread and fixed in fine dots on the adhesive side (one side) of the adhesive fabric. I'll keep it. This hot-melt adhesive softens or melts when heated, a portion of which penetrates into the strands of the mating fabric due to pressure, and is cooled and solidified to complete the bonding work. The inventor of the present application specially developed a method of processing interlining for the purpose of selectively heating the adhesive interlining and exhibiting a speed heating effect when applying high-frequency heating when adhering the adhesive interlining to the fabric. No. 59-1.56714, patent application No. 59-59
No. 8360 and Japanese Patent No. 101660/1983, but there was a need for further improvement in the treatment of the adhesive core before thermal bonding.

(Specific Object of the Invention) As a result of further research after the above proposal, the present inventor discovered a method that allows sewing manufacturers to easily and inexpensively dramatically increase the adhesive force of adhesive interlining.

(Structure and operation of the invention) To the surface of the interlining material cut according to the shape and size of the fabric to be bonded, apply a material with a weight ratio of 20 to 40 to the weight of the interlining material.
The target material was humidified by spraying water of 11 to 2% or water in the same weight ratio with 2% surfactant dissolved therein, that is, dropping it in a spray form and suctioning and discharging it from the back side of the interlining. It has been found that the adhesion strength can be significantly increased by layering it onto a fabric and feeding it into a flat hot press or continuous roller press. Although most of the experiments were conducted using a flat hot press, it was confirmed that the same effect could be obtained using a continuous roller press.

The drawing is a cross-sectional view showing the structure of a continuous humidifying device using a spray method on the surface of an adhesive core according to the present invention, and moving mechanical parts are omitted.) 3 is a spray nozzle, for example, a plurality of spray nozzles are arranged in a line. 4 is a cover for fixing the spray nozzle; 5 is an air suction box installed close to the belt conveyor 1 on the return path of the belt conveyor 1; and 6 is a large number of air suction boxes installed on the top surface of the air suction box 5 facing toward and close to the belt 1. 7 is an exhaust suction pipe connected to an exhaust blower (not shown), 8 is an adhesive core, and the henocell is placed on a belt conveyor with the side on which adhesive has been sprayed and fixed facing upward. Since the speed of the belt conveyor 1 and the air pressure of the sufu't,'-/zuru 5 can be easily controlled, the amount of humidification applied to the interlining 8 can be freely controlled. The interlining 8 moves while being lightly pushed and supported by the surface of the belt conveyor due to the downward flow of air. Note that when the belt conveyor makes one rotation and returns to the entrance of this humidifying device, moisture should not remain on the surface of the belt conveyor 1.

The water 9 may be tap water, but for the purpose of wetting the interlining 8t and speeding up penetration into the interlining, for example, a surfactant consisting of di-2-ethylhexylsulfoconomonophosphate) may be added to the water. Better results can be obtained by using 0.1 to 0.2% dissolved water.

We have summarized the measured values of the peel strength of various fabric types and interlinings combined with these when bonding with a small hot press using adhesive interlining 8 pretreated with the humidifying device as described above. Table 3 shows the type of interlining and type of fabric used in this experiment in Table 1 and Table 2. In this experiment, the woven fabric was cut into pieces of 50 m+ in width and 100 cm in length, and the adhesive interlining was cut into pieces of 40 iam in width and 100 m in length, which were overlapped during bonding. Also, after gluing is completed, leave it for 2 hours and then make the whole thing 50w wide.
The sample was cut at x, and the peel strength was measured.

As is clear from the above experimental results, water or about 2% surfactant (especially G-2-2) is applied to the surface of the adhesive core.
After humidifying with water in which sodium ethylhexyl sulfosuccinate (sodium ethylhexyl sulfosuccinate) is dissolved at a weight ratio of 20 to 40 inches (the optimum value is within 25 to 35 inches), it is layered on the mating fabric and bonded by heat and pressure. It was confirmed that the fitting strength could be enhanced. It has also been confirmed that the shrinkage after bonding is within about 1%.

This method of humidifying the adhesive interlining in advance with water and then applying heat and pressure to adhere them is fundamentally different from the commonly used method of using a steam iron. According to the method of the present invention, steam is rapidly generated only in the area where the adhesive core is located, and the hot melt adhesive is rapidly softened and melted by the moist heat effect. On the other hand, methods similar to conventional steam irons consume an unnecessarily large amount of steam and are uneconomical. In addition, in the roller type heat bonding method, the sample is heated by a hot plate and sandwiched between two moving Teflon belts to perform heating and pressure bonding, but in this case it is not possible to supply steam through the belt.
Even in the case of a continuous roller press, the same effects as shown in Tables 1 to 3 can be obtained. Humidification with water can make the subsequent bonding of the adhesive interlining to the fabric by heating and pressing 1.4 to 6 times stronger than conventional methods, and can speed up heating and pressing, making it economical. , the reliability of the sewing process is improved, such as less rice being harvested after bonding, and it is economically advantageous.
