Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a molded surface fastener having a piercing element with high slip resistance. It is.

0002

[Conventional technology]

Conventionally, in molded surface fasteners, the tip of the engagement element has a shape such as a hook shape, an umbrella shape, or an expanded head shape. , the mechanism that engages with the loop-shaped engagement element or the mechanism that engages the engagement elements with each other. It has been proposed that a combination element array is arranged (for example, Japanese Patent Publication No. 48-22768 Publication, Japanese Patent Publication No. 53-22889, Japanese Patent Application Publication No. 58-157404, Japanese Patent Application Publication No. 1987-157404 (Sho 63-127701, etc.).

[Problem that the idea aims to solve]

Conventional molded surface fasteners have loop-shaped engagement elements, such as hook-shaped or umbrella-shaped engagement elements. It engages by hooking onto the child, and has great engagement and disengagement force, but it is difficult to engage in the plane and horizontal direction. The adhesion is insufficient. Especially when the material to be engaged is a nonwoven fabric with a sparse fiber entanglement structure. Even if it is hooked and engaged, high engagement force cannot be obtained, and the Engagement force is small. Also, in the case of non-woven fabrics or fabrics with dense fiber entanglement structure, sufficient tension is required. Since a hooking engagement cannot be formed, high engagement strength cannot be obtained. Furthermore, spongy For materials that do not have an engagement element, such as sheets, conventional engagement elements cannot be used to engage and fix the material. There were drawbacks such as the inability to

0004 Therefore, the purpose of the present invention is to use fiber-entangled nonwoven fabrics and spongy fabrics that do not have special engagement elements. It also engages with materials such as striped sheets, and has sufficient anti-slip properties, especially against lateral forces. An object of the present invention is to provide a molded surface fastener having a constant effect.

[0005]

[Means to solve the problem]

The present invention provides a molded surface fastener having an engaging element on at least one surface of a base sheet. At least the distal end portion of the engagement element is branched into two or more parts, and the branched A molded surface fastener characterized in that at least one is a piercing element. .

[0006]

[Effect]

The molded surface fastener of the present invention has at least a tip branched into two or more parts, and the branched surface fastener has at least two or more branches. By using at least one of the elements as a piercing element, it is possible to eliminate the need for a special engagement element. It is not possible to pierce the piercing element into a nonwoven fabric with entangled fibers or a sponge-like sheet. It has a sufficient anti-slip fixing effect even against lateral forces.

【Example】

Next, the molded surface fastener of the present invention will be explained with reference to the drawings. 1 and 2 are schematic cross-sectional views of a molded surface fastener of an engagement element having a piercing element, and FIG. 1 shows an engagement element 3 consisting of a piercing element 4 and a hook-shaped element 5 on one surface of a base material 2. have. It is preferable that the height H ₁ of the stabbing element 4 of the engagement element is higher than the height H ₂ of the hook-shaped element 5 in terms of stability against horizontal forces. FIG. 2 shows an engagement element 3 with a piercing element 4 and a hook-shaped element 5 on one side of a substrate 2, and a conventional engagement element or embedded element 6 on the other side of the substrate.

FIG. 3 is a schematic cross-sectional view of an example of a molded surface fastener in which a stab engagement element and a normal engagement element are mixed, and an engagement element 7 consisting of a stab element on one surface of the base material 2, and a hook. Ordinary engagement elements 8 such as a type engagement element or an umbrella-type engagement element are mixed. It is preferable that the height H ₁ of the engagement element 7 made of a stabbing element is higher than the height H ₂ of the ordinary engagement element 8 in terms of fixability against horizontal forces.

[0009] The material for the molded surface fastener of the present invention is not particularly limited, but resin is preferred in terms of processability. Preferred, for example polyolefins or olefin copolymers, polyesters, Polyamide, vinyl chloride polymer, polyester elastomer, polyamide elastomer One type of polymer such as polymer, polyurethane, or other thermoformable polymer, or Two or more polymer compositions are melt-extruded or injection molded to form a base sheet. A molded surface fastener having engaging elements on one or both sides. Few engagement elements In each case, the tip is cut and shaped so that it branches into 2 to 5 elements. At least one element made of fiber-entangled nonwoven fabric or fabric without a special engagement element, Tip shape that has the ability to pierce sponge-like sheets, etc., such as upright or curved Make it an upright or slanted type with a slope. In addition, other elements may be attached to the engaging element with the stabbing element. When coexisting with the That's fine.

0010 The arrangement of the engagement elements with the piercing elements is designed based on the intended use of the molded surface fastener. However, if the purpose is simply two-dimensional anti-slip fixation, the piercing element may be used. Although it is possible to use the engaging element alone, it is necessary to For example, when the purpose is to fix the piercing element and the engaging element as shown in Fig. 1, Molded surface fasteners of coexisting engagement elements or engagement of piercing elements as shown in Figure 3 Molding in which an element and an engagement element with a hook-type engagement function coexist It is preferable to use a hook-and-loop fastener.

[0011] The molded surface fastener of the present invention can be used, for example, in the industrial field for soundproofing. ・Installation of sound insulation materials, heat insulation materials, etc., fiber-entangled nonwoven fabrics, fabrics, sponge sheets, etc. How to fix carpets, carpets, mats, etc., and interior materials such as automobiles. It can be used for fixing, anti-slip materials for various porous sheets, etc.

0012

[Effect of the idea]

The molded surface fastener of this invention not only has excellent two-dimensional anti-slip fixing properties. It also has great engagement strength against the combined action of three-dimensional sliding and peeling. Therefore, special engaging elements such as fiber-entangled nonwoven fabrics, fabrics, and sponge-like sheets are used. It has an excellent engagement and fixing effect even on sheet-like materials that do not have the same properties.
