Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention In the present invention, a loop-shaped engaging element (A) made of a multifilament and a loop-shaped engaging element (B) made of a monofilament are erected on a fabric surface which is a base sheet surface. The present invention relates to a female side surface fastener member with improved prevention of sagging (falling down) of a loop-shaped engagement element against repeated pressing and heat pressure, and in particular, engagement with a surface fastener member of a type in which both engagement elements are mixed. The present invention relates to a female side surface fastener member having improved properties.

[0002]

2. Description of the Related Art Generally, a surface fastener has a female side fascia member in which a loop-shaped or arch-shaped engaging element is erected on one surface of a cloth serving as a base, and a hook shape or a mushroom shape engaging with the engaging element. And a male side surface fastener member in which the hook-type engaging element is also erected on one surface of the base fabric, and both members are joined by pressure-contacting the both members, and both adherends to which the respective members are attached Are integrally joined and fixed. And such a surface fastener is easy to put on and take off, as a stopper for opening and closing clothes, shoes, bags, etc.
Further, it is widely used as a fitting such as a seat cover for a seat or a bedding seat cover typified by a train or an airplane.

By the way, even when used in this clothing,
Also when used as a seat cover, in particular,
The female side surface fastener member is subjected to frequent washing in order to remove dirt from use, frequent ironing in accordance with it, and further operations such as collecting and stacking them together for processing such as distribution. Heat or pressure is applied to the loop-shaped engaging element of 1, and the state in which the loop remains tilted or sag (tilted) occurs.
If the loop becomes tired (falls down) and sticks to the surface of the base body, the engaging element (hook) on the male side fastener member side cannot catch the loop in the above state, and the engaging points of both are reduced. It has been pointed out as a problem that the engagement effect is weakened or the engagement becomes impossible in some cases.

In order to solve the problem caused by the sag of the loop, for example, in Japanese Utility Model Publication No. 63-41935 or Japanese Utility Model Publication No. 2-43207, a part of a normal loop is used together with a partially hard yarn. Both types of female side fasteners are used as a closed loop, or female side fasteners made by weaving a rigid projecting pile with a core together with an ordinary loop, and using a loop using this hard thread or a rigid projecting pile. A device for preventing sagging is disclosed.

However, the specific proposals disclosed in these documents are, in the former case, a structure in which loops using hard threads are arranged in three rows at both ends in the width direction of the surface fastener. , Both ends in the width direction of the male side fastener on the hook side cannot engage with the three rows of loops at both ends of the female side fastener, and the both ends are in a raised state, resulting in poor engagement and Disengagement becomes easy. In addition, since the ordinary loop rows in the middle portion are too many and the loops using the hard thread that is a resistance against heat pressure such as ironing are too far apart, the effect of preventing the settled loop of the middle portion loop is small. Further, the latter proposal also has the same problem as the former case in that wide and rigid projecting piles are provided at both ends in the width direction of the surface fastener.

[0006]

SUMMARY OF THE INVENTION Therefore, according to the present invention, the former loop-shaped engaging element is prevented from sagging (falling) by arranging a monofilament engaging element in a mixed manner with a multi-filament loop-shaped engaging element. The present invention provides a female side surface fastener member having a small amount of fatigue of the loop-shaped engaging element and excellent engaging property with the male side surface fastener in a spiral side female side surface fastener member. still,
In the present specification, the term "loop-shaped" of the loop-shaped engaging element is used to mean a literal loop shape and also an arched shape.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below based on the embodiments in the drawings, but the present invention is not limited to these drawings. FIG. 1 is a perspective view of an example of the female side surface fastener member of the present invention cut into an appropriate length, and FIG.
FIG. 6 is an enlarged cross-sectional view (cross-sectional view in the width direction) taken along the arrow X. 3A to 3G are enlarged cross-sectional views in the width direction showing another embodiment of the female side surface fastener of the present invention.

When a cloth, especially a woven cloth, is used as the base (sheet) 1 of the female side surface fastener, the loop-shaped engaging element is generally formed by using a filament forming the engaging element. While weaving in the length direction of the woven fabric, a loop is formed in the length direction of one side of the woven fabric. Therefore, the number of the loop-shaped engaging elements arranged in the width direction of the surface fastener is determined by the number of the filaments woven in the width direction of the woven fabric. In the case of a normal female side fastener having a width of 25 mm, 20 to 40 pieces (more limited to 30 to 31 in an intermediate region excluding the ears 2 of 1.5 to 3 mm at both ends thereof).
Books) are arranged, and the array density in this width direction is
Even in the case of a hook-and-loop fastener having a larger width as the base body, it is almost the same and does not change. That is, usually, the number of arrays (array density) of 1 to 2 per 1 mm in the width direction of the surface fastener.
Therefore, the present invention is also premised on this array density.

In the surface fastener of the present invention shown in FIGS. 1 and 2, the engaging element (A) 3 made of multifilament and the engaging element (B) 4 made of monofilament are arranged in each row in the width direction of the fastener. Is an example in which engaging elements (A) 3 made of multifilaments are arranged alternately on both sides in the width direction, and the surface fastener of the present invention in FIGS. 3 (a) to 3 (c) is In the width direction, the number of engagement elements (A) 3 made of multifilaments increases from one row of engagement elements (B) 4 made of monofilaments to two rows, three rows, and four rows, respectively. The example of is also an example in which the engaging elements (A) 3 made of multifilaments are arranged at both ends in the width direction. In the present invention, the arrangement of the engaging elements (A) 3 made of multifilaments at both ends in the width direction of the surface fastener is
Although not an indispensable constituent element of the present invention, the illustrated examples show a more preferable embodiment, and the same applies to the following illustrated examples.

In the surface fastener of the present invention shown in FIGS. 3 (d) to 3 (f), in the width direction, the engaging elements (B) 4 made of monofilaments are arranged with respect to two rows of engaging elements (made of multifilaments). A) 3 increases in 2 rows, 3 rows, and 4 rows, respectively, and in each case, the engaging elements (A) 3 made of multifilaments are arranged at both ends in the width direction. Further, in the surface fastener of the present invention in FIG. 3 (g), the engaging elements (B) 4 made of monofilaments are a mixture of one row and two rows and the engaging elements (A) made of multifilaments in the width direction. ) 3 is also a mixture of 2 to 4 rows, and in each case, the engaging elements (A) 3 made of multifilaments are arranged at both ends in the width direction.

As shown in these figures, the settling (falling) of the engaging element (A) 3 made of multifilament
In order to prevent this, the engaging elements (B) 4 made of monofilaments are mixed, but it has been found that the engaging elements (B) 4 made of this monofilament need to be limited to one row or two rows. . What if
This is because if the number of rows is three or more, the width area in which the male side surface fastener cannot be engaged with the hook becomes large, the engaging property of both fasteners there is deteriorated, and both engaging portions are easily disengaged.

Further, the number of arrayed engaging elements (A) 3 made of multifilaments is 4 rows at most, and when the number of arrayed elements is more than this, the engagement made of monofilament as a resistance against the sag (tilt) occurs. This is because the effect of the element (B) 4 is weakened.

At both ends in the width direction of the surface fastener, at least one engaging element (A) 3 made of multifilament is provided.
It is preferred to arrange rows, preferably 2-4 rows. The presence of the engaging elements (A) at both ends eliminates the non-engageable regions of both the male and female fasteners at the outermost ends in the fastener width direction, and prevents the male parts from engaging. It is possible to prevent the disengagement of the side fasteners from being easily disengaged due to the lifting at the both ends in the width direction.

By satisfying the basic requirements and additional requirements of the present invention as described above, the loop-shaped engaging element does not deteriorate in the engaging property in this kind of hard and soft loop mixed type surface fastener. The surface fastener can be effectively prevented from sagging, and the monofilament diameter of the engaging element (B) 4 is 0.15 to 0.30.
mm, 20 in denier units usually used in the textile field
It is preferably 0 to 700 denier (dr). If this diameter is smaller (thin) than 0.15 mm,
When the engaging element (A) 3 made of multifilament is not set to the function as a resistor and becomes thicker than 0.30 mm, the engaging element (A) 3 and the male side surface The repulsive force of the fastener with respect to the hook increases, the engagement between the two surface fasteners decreases, and the texture becomes hard, which is not preferable.

Furthermore, it has been found that the relationship between the heights of the two engaging elements (A) and (B) to be mixed is present as a factor for the requirement to further exert the intended function of the present invention. That is, in the loop height from the surface of the base body 1, the engaging element (A) 3 made of a multifilament and the engaging element (B) 4 made of a monofilament have a height ratio of the engaging element (A). : Engaging element (B) = 1: 0.5
It has been found that it is preferable to fall within the range of ˜1: 1.5. This is because the engagement element (A) 3 is the engagement element (B) 4
If the engaging element (B) is too high, the engaging element (B) does not function as a resistor against the fatigue (tilt) of the engaging element (A), and conversely, the engaging element (B) 4 Engaging element (A) 3
Even if it is too high, the engaging element (B) covers the engaging element (A) and covers it, and if it gets tired by heat pressure such as ironing, the tendency becomes more severe. It appears to be. From the above reason, more preferably, the engaging element (A) made of multifilament is more preferable than the engaging element (B) made of monofilament.
4 to the same level or less, that is, the former engagement element (A): the latter engagement element (B) = 1: 0.5 to 1: 1
It has been found that it is more effective to fall within the range.

As the fiber material of the engaging element (A) 3 made of multifilament, a synthetic fiber multifilament yarn having a single fiber fineness, which is generally adopted in this type of female surface fastener member, is used. Its thickness (single fiber fineness) is usually 2 to 50 denier, preferably 10
~ 30 denier. Further, as the material thereof, polyamide, polyester, polyacrylonitrile, polyolefin or the like is usually used. As the fiber material of the engagement element (B) 4 made of monofilament, the same material as the engagement element (A) 3 usually made of multifilament can be used, but in some cases, it has higher rigidity. High performance fiber materials such as wholly aromatic polyester and para aramid can also be used.

Insertion into the substrate 1 for loop formation using these multifilaments and monofilaments, when the fabric constituting the substrate 1 is a woven fabric, a conventional needle loom, rapier loom, water jet loom,
It can be carried out by using an air jet loom or the like and weaving it while intermittently inserting it into a part of the warp. When the cloth constituting the base body 1 is a knit, it can be knitted by various knitting machines such as a normal tricot knitting machine, a Russell knitting machine, a circular knitting machine, and a flat knitting machine.

As the substrate 1, any cloth conventionally used as a substrate for this kind of surface fastener member can be used. The cloth refers to a woven fabric, a knitted fabric, a non-woven fabric or the like using a fiber material. The fiber material of the cloth may be a conventionally known fiber material, and is not limited at all.
