Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to the structure of an important fastener.
This invention relates to a cloth fastener with two types of male elements that are erected on a male surface.

(Prior art) Japanese Patent Publication No. 46-5417 or Japanese Patent Publication No. 85-55
! As disclosed in the publication, cloth fasteners generally consist of two male and female parts that are removably engaged with each other.
On its male surface, there is a bulge-shaped engaging male element A (1) made of a monofilament thread of a synthetic linear polymer shown in Fig. 2.
Alternatively, a large number of hook-shaped male engaging elements B (2) shown in FIG. 8 are erected, and the male elements A - B (
1) with a pile or female element (5) that engages with (2).

Due to its easy attachment, the above-mentioned cloth zipper is increasing in demand not only for industrial materials such as automobiles and packaging, but also for clothing, diapers, shoes, etc. The above-mentioned bulge-head type is usually also called the hard type. Although it has the characteristics of being rigid as shown in Fig. 6 and having high engagement and peel strength, that is, high strength as shown in Figs. There are limited uses. The reason for the poor durability is that the head of the bulge-shaped male engaging element A (1) is easily torn apart, and the female pupil (
5) The loop pile yarn is easy to cut.

On the other hand, the mold type product has the strength shown in Figure 6, that is, the shear strength is low compared to the expansion head type, but it has the advantage of smooth attachment and detachment and less loss of engagement force even after repeated use. Demand is increasing, especially in the clothing and footwear fields, which are frequently used.

However, when used in applications where the shear strength acts strongly after face-to-face contact with the male surface, such as when used as a fastener for a belly band, band, arm cuff, or fastening band for packaging materials, the drawback is that the shear strength, that is, the horizontal pull strength, is insufficient. has been done.

However, conventionally known cloth fasteners have the above-mentioned bulge-like shape,
Or, either one of the hook-shaped male elements stands alone on the male surface, and the defects of one tend to appear as they are.

In order to overcome the drawbacks of such dilatation-shaped or hook-shaped male elements, one of the applicants of the present application filed Japanese Patent Application No. 55-90808, in which the dilatation-shaped male elements and the hook-shaped male elements were combined with the same male surface. We proposed a fabric fastener that is distributed on a base fabric and a method for manufacturing it. The product obtained by the invention is superior in that it provides an intermediate function compared to the one in which both male and female elements are individually installed. However, in order to carry out the invention, it is necessary to It requires a combination of bail weaving technique and sashimi weaving technique to form the loop, and requires the use of a special loom and advanced technology, which has the drawback of being difficult to implement.

The object of the present invention is to eliminate the drawbacks of the above-mentioned dilatator type, hook-type male face, and hybrid male face.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides a fabric fastener consisting of male and female surfaces that are removably engaged with each other, in which a large number of bulge-shaped improved male elements C are erected. segment C
A segment B in which a large number of hook-shaped engaging male elements B are erected is arranged on one surface of the same band to form a male surface, and a female element to be attached to and detached from the male element C and male element B is attached to the band. The other surface is erected to form a male surface, and the boundary line between the working part of the male bulge C and the head is shifted toward the base fabric side from the center point P of the head curved surface. This is a characteristic feature.

(Function) The fabric fastener according to the present invention has segment B of the hook-shaped male element B which has sufficient beer strength, and segment C of the improved male element C in the form of a bulge having high strength as a function against lateral pulling resistance, that is, shear strength. By arranging the male elements on the same plane to form a male surface, the above-mentioned drawbacks of the male surface having single male elements erected can be overcome.

The present invention will be specifically explained below with reference to embodiments shown in the drawings.

(Example) The fabric fastener of the example has a structure suitable as a fastening material, and as shown in Fig. 1, a male surface (7) is attached to the - side of the narrow band (6), and A male surface (8) that removably locks S is formed attached to the other surface.

The male surface (7) has a bulge-shaped improved male element 01 (3
) C(9) and a segment Bα having a large number of hook-shaped engaging male elements B(2) erected.
4 is stuck. The male element 01 (3) is @
Unlike the conventional mushroom shape shown in Fig. 2, as shown in Fig. 4, the head height (Hl) is set to 17
Shape it into a cherry shape larger than 2.

In addition to this, as shown in Figure @6, it is also possible to use a round rivet-shaped male resistor 02 (4).

In short, improved male element 01 (3), male element 02 (
4) The boundary line (L) between the engineering part l and the head part ■ of the male element
l is the center of each external curved surface of the head (Pl), which is shifted toward the base fabric side.In the case of the round flat rivet type shown in Fig. 5, the head height H! is the head diameter d! 1/2 joint venture ≠ Compromise 1 → or larger.On the other hand, θR & H3 bit and L, '/2dlt1] sword\zag, but it's summer.

In order to obtain the aforementioned cherry shape or round rivet shape, when the head (locking part) is granulated according to the procedure described in Japanese Patent Publication No. 46-5417, the polyolefin synthetic linear polymer is It can be obtained by selecting fiber manufacturing conditions such as polymer structure, degree of polymerization, spinning conditions, and the above-mentioned granulation conditions, such as heating temperature and speed of the material to be processed.

The aforementioned cherry-shaped male element (FIG. 4) and round laribet-shaped male element (FIG. 5) differ from the conventionally known male element (FIG. 2) in the following points. In other words, both of the improved types differ from the conventional one in that they have sufficiently strong shear strength, but have less peeling strength.
There is little resistance when attaching and detaching when peeling stress is applied, and there are fewer factors such as the swelling head being torn to pieces or the loop pile yarn serving as the engaged surface being cut even when used repeatedly.

This increases the tightening force when used for interviews,
It also exhibits an excellent function that prevents slipping when used as a belly band, corset, band, etc., that is, when a force is applied in the shearing direction.

Furthermore, as shown in FIG.
(3) or segment C (9) comprising 02 (4)
By using the segment BαQ of the hook-shaped male element B (2) in combination, it is possible to produce a functional material that has a stopping function, that is, only the ends have sufficient peeling force.

-1 The loop pile product forming the female element (5) which becomes the engaged surface is a pile product including a woven or knitted product made of nylon or polyester synthetic linear multifilament or a raised product thereof. Yes, it can be used as appropriate depending on the purpose.

In addition, as the base fabric for segments C (9) and B (10), in addition to the above-mentioned nylon and polyester fibers, natural or recycled fibers can be used alone or in combination. In addition, other materials such as woven or knitted fabrics can be used for these base fabrics. Films, foams, and the like can be combined and used by high-frequency welding, ultrasonic welding, gluing, or sewing with a sewing machine.

In the present invention, the synthetic fibers include nylon 6, nylon 66,
Nylon 610. Polyamides which are nylon 11 or copolymers thereof, polyesters represented by polyethylene terephthalate obtained by condensation polymerization of aromatic dicarboxylic acids and glycols, polypropylene, and polyethylene fibers.

The present invention will be explained in more detail with reference to specific examples below. The lateral pull or shear strength referred to in the specific examples refers to the stress in the plane direction as shown in FIG. (1) ■ 25 sokuto, contact surface length (a = 50 m/m
The intensity in the case of is expressed immediately. Peeling (beer) strength refers to the stress when a peeling force as shown in FIG. 7 is applied, and as a numerical value, the strength at i ; x 25 m/m in the end face is expressed as I.
