The apparel environment according to the fabric design is an overall environment that reflects the overall technology, knowledge, and industrial development of the society.As a general rule, the values and consciousness of a society have a significant impact on the development and development of apparel materials. I have been.

In other words, given the trend of society that pursues social humanity and prioritizes individual feelings, modern clothing production is in addition to the simple physical functions so far, and the sensory functionality that gradually provides human psychological satisfaction and aesthetic pleasure. The development of clothing (fabric) material in the direction of importance.

For example, in the fabric of apparel, sensory functionality is all about sight, touch, hearing, and smell. In the decades past, in the textile and apparel industry, the shape and quality of fabrics and their associated fabrics Efforts have been made to objectively measure and evaluate performance.

Objectively measuring the sensory performance of fabrics aims to identify sensory properties that contribute to the perception of the quality of fabrics and apparel, taking into account the end use of the apparel product, and to objectively quantify and evaluate them.

Therefore, in the textile and clothing industry, fabrics and clothes are produced to meet consumer needs in various aspects such as price, quality, fashion, and comfort, so that producers, wholesalers, and retailers can also improve the sensory performance of fabrics. Efforts are being made to establish a model that can objectively quantify and predict this, and to utilize it in the manufacture, distribution, and sale of fabrics and clothes.

By the way, the evaluation of the touch and visual performance of the fabric is being developed, but the development to systematically evaluate the sensory performance of the fabric related to hearing has been very poor until now.

For example, in order to develop a high value-added fabric that realizes auditory sensibility, a system was needed to evaluate sensory comfort with respect to fabric friction sounds and quantify it objectively.

In other words, even though the apparel industry has developed so far, it has been focused on the creation of clothing with various functions by designing the abrasion, breathability, and waterproofness of the fabric before the garment is finished. Efforts to make clothing by measuring the noise in advance and considering it as well as the design of the clothing and the acoustic sensitivity were insufficient.

The second fabric sample 70 receives the force to be pulled by the first weight 61 connected, so that the horizontally moving tow wire 60a is released from the pulley and the movable table 58 moves to one side (right side) of the device. At this time, the horizontal movement traction wire (60a) is in a tension state.

Therefore, in the state where the second weight 66 is heavier than the first weight 61, the rotation of the two-stage pulley of the wire pulley 62 as the operation piece is stopped, and the second weight 66 is fixed than the initial position. When the operation piece is removed from the piece groove 68 of the pulley in a state of being raised above the height, the horizontal and vertical movement traction wires 60a of the wire pulleys at one end and the second end are due to the weight of the second weight 66. The second weight 66 is lowered as the 60bs are wound or unwound in the order described above, so that the movable unit 58 pulls the second fabric sample 70 to the other side of the apparatus (left). 53) Move smoothly on.

At this time, as shown in Figures 1 and 2, the friction sound is generated at the frictional position (P) in contact between the second fabric sample 70 moving in the movement path in contact with the first fabric sample 30, The fabric friction sound generated in the noise input unit 110 to be described is input to measure the fabric friction sound, such a noise measurement step will be described in detail below.

Therefore, as described above, the second fabric sample 70 of the present invention is connected to the moving means 50 and moves along a path in friction with the first fabric sample 30 to generate friction noise between the fabrics. Is provided.

Next, Figures 1, 3 and 4 shows a moving speed adjusting means 90 for varying the moving speed of the second fabric sample 70 according to the material of the fabric in the apparatus of the present invention, such a bone The moving speed adjusting means 90 of the present invention is provided on the other side of the apparatus body 10 so as to variably adjust the moving speed of the second fabric sample connected to the moving means while being installed in association with the moving means 50. .

That is, as shown in Figures 3 and 4, the speed adjusting means 90, the shaft enclosing member 92 and the shaft enclosing the close contact with the driven shaft 64b of the moving means rotation switching box 64, and the shaft Consists of the operating lever means 94 provided to adjust the moving speed of the fabric sample by reducing the degree of friction between the shaft enclosure 92 and the driven shaft 64b according to the degree of pulling while being connected to one end of the enclosure 92 do.

Therefore, the speed adjusting means 90 of the present invention, as described above, the movement of the horizontal movable traction wire 60a and the vertical movement traction wire 60b connected between the movable table, the one end pulley and the second pulley and the second weight. Allow you to adjust the speed.

For example, as shown in FIGS. 3 and 4, the drive shaft 64a to which the wire pulley 62 to which the traction wire is wound is fastened is connected to bevel gears at right angles in the rotation switching box 64. Direction of the driven shaft 64b protrudes out of the gearbox 64, and eventually the rotation of the driven shaft 64b associated with the drive shaft rotated in accordance with the movement of the towing wire and the rotation switching box 64 is added or subtracted. In the end, the moving speed of the movable table 58 and the second fabric sample 70 fixed thereto is adjusted.

At this time, the shaft enclosure 92 surrounding the driven shaft 64b is composed of a steel plate 92b on the outside and a rubber 92a on the inner side to adjust the rotation of the driven shaft 64b with a frictional force according to the degree of adhesion. .

3 and 4, the steel sheet and the rubber of the shaft enclosure 92 are wrapped around the shaft, and the contact portions thereof are connected to the bolt 92d through the connecting piece 92c in a state where one end contacts each other. Fastened and fixed).

In addition, the operation lever means 94 is connected to the connecting piece 92c. Specifically, a screw shaft 94a is connected to the connecting piece 92c, and the screw shaft 94a is an apparatus body part 10. It is connected to the connecting rod 94c supported through the guide ring 94b installed on the supporting block 10e on the other side.

At this time, the first link 94d connected to the end of the connecting rod 94c is hingedly connected to the second link 94e connected on the block, and the operation handle 94f is connected thereto.

As a result, when the operating lever means 94 of the speed adjusting means 90 is operated in the apparatus of the present invention, the shaft enclosure 92 is in close contact with the degree of close contact with the driven shaft 64b of the rotation switching operation 64. As a result, the rotational speed of the driven shaft is adjusted or adjusted, and the movement speed of the drive shaft 64a, the wire pulley 62, and the traction wire is adjusted.

That is, when the manipulation knob 94f of the manipulation lever means 94 is pulled, the first link 94d moves forward and backward along the axis of the second link 94e, and this movement distance eventually leads to the connecting rod 94c and the shaft enclosure. Determining a closeness between the 92 and the driven shaft 64b of the rotation switching box 64 to variably adjust the moving speeds of the wire pulley, the movable table and the second fabric sample associated with the driven shaft by the variable frictional force. To make it possible.

Therefore, the user can easily adjust the moving speed of the second fabric sample 70 when operating the device, rather than using the speed reducer in the existing device, for example, according to the fabric material in the device operation, for example, thin cloth or thick By setting the moving speed of the fabric corresponding to the cotton fabric, the degree of friction noise can be freely adjusted, making it easy to measure the fabric noise and improving the measurement accuracy.

Next, the noise input unit 110 of the present invention, as shown in Figures 1 and 2, when the fabric is disposed directly above the friction position (P) of the first and second fabric samples 30, 70 Friction noise between the materials is input, specifically, it may be provided as a bar-type microphone which is fixed to the fixing table 112 disposed directly on the friction position (P) between the fabric sample to one side of the device body portion.

At this time, as shown in Figure 7, the microphone noise input means 110 is a device control unit (C) and noise input unit (I), for example, the friction noise between the fabric that is electrically connected to the amplifier and input device control unit The transfer is handled.

1 and 2, the fabric friction sound measuring apparatus 1 of the present invention is installed to move in an endless track in the longitudinal direction at one side of the device body 10, the moving means The wire 132 is connected to one side of the mobile unit 58 of the 50 and the wire 132 is fastened and connected to the pulleys 134 installed on both vertical bodies 10b of the stationary body unit to the mobile unit. It may be provided with a speed detecting means 130 including an encoder 136 provided to detect the moving speed of the fabric sample.

That is, the encoder 136 measures the moving speed of the wire 132 connected to the moving table 58, and the measured value is an apparatus electrically connected to the encoder 136, as shown in FIG. The display unit D is connected to the control unit C.

Therefore, as shown in Figure 7, looking at the noise input configuration of the fabric friction sound measuring apparatus 1 of the present invention, the friction noise between the fabric in the upper portion of the fabric friction position (P) to the noise input means 110 of the microphone The input value is transferred to the device control unit C through a noise input unit I such as an amplifier, and at the same time, a speed measurement of the encoder 136 that detects the wire speed according to the movement of the mobile unit 58 is performed. The value is displayed on the display unit (D) and transmitted to the device control unit (C). Finally, the device control unit (C) compares and analyzes data, noise values, and moving speed values according to the material of the fabric.

In other words, the fabric friction sound measuring apparatus 1 of the present invention is very smooth movement of the mobile table compared to the existing device, and in particular, because the movement speed is freely adjusted according to the material of the fabric, the operation of the device during the measurement of the fabric noise or This allows for greater measurement accuracy and the breadth of the data collected.

On the other hand, when the friction sound measurement of the fabric friction sound measuring apparatus 1 of the present invention is summarized, the first fabric sample to measure the friction noise of the desired fabric in one fabric sample fixing means 20 of the device body 10 Place (30).

At this time, the first textile sample 30 or the second textile sample 70 rubbed thereto may be made of a natural material, a composite material, or a natural material and a composite material such as cotton fabric, hemp fabric, wool fabric, dog fabric, blend fabric, and fabric. As long as it can measure the parallel friction sound, it is possible, but this is only an example.

Next, the one end 70a of the second textile sample 70 having a predetermined width and length is fixed by using the fixing piece 56 mounted on the upper side of the movable table 58 of the moving means 50, and the textile sample The other end of the 70b is connected to the first weight 61, so that the second fabric sample 70 is moved vertically through the device holder (12).

As described above, when the device setting of the first and second fabric samples 30 and 70 is completed, as described above, the piece groove 68 of the two-stage pulley 62b of the wire pulley 62 is replaced with the operation piece such as the driver. ), The position of the movable table 58 connected to the traction wire by the rotation of the wire pulley 62 is moved from the initial position to one side of the device, and the handle 94f of the operation lever means 94 of the speed adjusting means 90 ) To adjust the moving speed by adjusting the degree of close contact between the driven shaft 64b and the shaft enclosure 92 of the rotation switching box (64).

When the operating piece is separated from the piece groove 68 in a state of tension between the 62, the second fabric sample 70 is rubbed by falling of the second weight 66 that is heavier than the first weight 61. At position P, it is moved while generating friction noise with the first textile sample 30.

At this time, if the moving speed is displayed through the encoder 136 and the de-playing unit (D), the user performs the noise measurement several times using the speed adjusting means 90 to approach the desired moving speed.

As shown in FIG. 7, the noise input into the microphone, which is the noise input unit 110, is processed by the device controller C through the noise input unit I.

At this time, the friction noise caused by the interference between the fabrics is different depending on the surface degree of each material and the woven fabric in the state of wearing the clothes, usually about 65㏈ for the fabric with a large noise level (㏈) Point.

For reference, the noise level caused by the friction of the fabric is about 35㏈ ~ 65㏈ according to each material, and the wearer of the clothes and the people around them can feel hearing about 50 대략, Even the fabric material may vary according to the design difference of the fabric.

Accordingly, the fabric friction sound measuring apparatus 1 of the present invention makes it possible to apply the friction noise obtained from the fabric samples 30 and 70 to the fabric design, so that the noise is less before the garment is made. It is possible to design the fabric so that not only the design of clothing but also the noise level, that is, the physical properties of the fabric, enables the design of the fabric for the satisfaction of emotion.
