Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a flame-retardant hook-and-loop fastener with improved 7-ogging properties.

[Conventional technology]

Conventionally, hook-and-loop fasteners have been used in many ways as a simple engagement material, and have been used in a wide range of applications, such as by randomly attaching or press-fitting them together. Vehicle seats, etc. were first developed in 1977.
It has been proposed in JP-A No. 20257, JP-A-6054498, JP-U-61-79964, JP-A-61176390, JP-A-63-15983, and the like.

[Problem to be solved by the invention]

Conventional hook and loop fasteners are not flame retardant, so
It is difficult to apply it to applications that require flame resistance, such as seats and interiors for automobiles, aircraft, and trains, interiors and furniture of hotels, halls and department stores used by the public, etc. Hook-and-loop fasteners used in such applications can be treated with flame retardants1, but if the amount of flame retardants added is increased to improve flame retardancy, the flame retardants usually sublimate or volatilize during use. Glass surfaces become cloudy due to substances, so-called "
Fogging becomes a problem. However, if a flame retardant that does not cause 7-oging is used, the flexibility after flame retardant treatment will be impaired and the retention function of the hook-and-loop fastener will be reduced, and if the retention is repeated or bending is applied, the flame retardant will fall off. There are problems such as loss of flame retardant effect. The present inventors investigated the fogging values of surface 7 aseners coated with various flame retardants, and found that the surface fasteners coated with a specific flame retardant retain their flame retardancy even after repeated use over a long period of time. The present invention was achieved based on the discovery that the retention function of the hook-and-loop fastener was small. Therefore, the object of the present invention is to achieve both flexibility and flame retardancy,
Another object of the present invention is to provide a flame-retardant hook-and-loop fastener with improved fogging properties.

[Means to solve the problem]

The present invention is provided with a flame retardant and has a fogging value of 0.
It is a flame-retardant hook-and-loop fastener with a weight of 1 to 2.0 mg. Further, the present invention provides a resin composition containing a flame retardant or a fibrous sheet containing the resin composition on the back side of a hook-and-loop fastener, and a fogging value of 0.1 to 2.0 mg.
This is a flame-retardant hook-and-loop fastener. Such flame-retardant hook-and-loop fasteners are used, for example, in automobiles, trains,
Vehicle interior parts, skin materials, seats, etc. that require flame retardancy for ships, aircraft, etc. (hereinafter collectively referred to as "vehicle use")
Fixing carpets, etc., fixing exhibits on walls or panels, fixing wall coverings or ceiling materials, sofa-1
It is preferably used for fixing covers to furniture such as chairs and beds. The hook-and-loop fastener used in the present invention has a loop-shaped retention element obtained by weaving and weaving fibers such as polyester fibers, polyamide fibers, polyolefin fibers, polyvinyl chloride fibers, acrylic fibers, and regenerated cellulose fibers. Even if it is a female hook-and-loop fastener, the male hook-and-loop fastener is made of knitted or woven material that has a hook-like engagement element that engages with the female hook-and-loop fastener, or a thermoplastic resin such as polyester, polyamide, polyolefin, polyvinyl chloride, polyurethane, or hardened. It may also be a molded male hook-and-loop fastener obtained by plasticizing a plastic resin. Moreover, a group of embedded elements for embedding in the molded body may be provided on other surfaces of the base material as necessary. The fogging value of the flame-retardant hook-and-loop fastener of the present invention is 0.1~
It is 2.0 mg. When the fogging value reaches 2.0 mg, it not only causes fogging on glass and metal surfaces, but also
It softens the material that makes up the hook-and-loop fastener and reduces its retention function. Furthermore, if the amount is 0.1 mg, the hook-and-loop fastener will be hardened and its bending resistance and repeated engagement functionality will be reduced. 7 Ogging value used for flame retardant hook-and-loop fasteners 0.1-2
．． For 0 mg of flame retardant, a flame retardant that has substantially no fluidity at room temperature and a flame retardant that is substantially liquid at room temperature are combined in a composition ratio of 1:
O, used in a mixture in the range of 1 to 1.0. A flame retardant alone, which has virtually no fluidity at room temperature, will harden the hook-and-loop fastener, impairing its engagement properties and bending resistance. In addition, excessive use of flame retardants, which are essentially liquid at room temperature, may soften the binder resin and other constituent materials of the hook-and-loop fastener, reducing its retention function, reducing color fastness, and causing migration. This is not preferable because it increases the fogging property. In addition, it is preferable to use a liquid flame retardant having a high boiling point or decomposition point of at least 180° C. at ordinary pressure, a flame retardant that is liquid at ordinary temperature and sticks to the object to be treated, and the like. Examples of flame retardants include organic phosphate esters,
1 selected from organic phosphites, halogen-containing organic phosphates, halogen-containing organic layer phosphates, condensates of these compounds, organic halogen compounds, etc.
or more than one type of flame retardant. The flame retardant can be applied to the hook-and-loop fastener by dipping or coating the hook-and-loop fastener in a solution or dispersion of the flame retardant, or a composition solution in which a binder resin is added. , a flame-retardant resin composition obtained by adding to a solution or dispersion of a resin mainly composed of an elastic resin such as acrylic resin, acrylonitrile-butan, diene-based resin, or silicone-based elastic resin, or the above-mentioned flame-retardant resin. A method for forming a flame-retardant resin layer or a flame-retardant fibrous layer by impregnating a fabric such as a woven fabric, knitted fabric, or non-woven fabric with the composition and applying the obtained fibrous sheet to the back side of a hook-and-loop fastener. and so on. The amount of flame retardant applied is determined by the effect of the flame retardant used, but it is 15 to 10
0g/m" is appropriate. The fogging value in the present invention is as shown in FIG. A glass plate (9) is placed in the chamber and sealed, and a cooler (10) for cooling the glass plate is brought into contact with the top of the glass plate.Then, the glass plate is heated to a temperature of 100± 0.5°ci = 16 hours to allow the substances generated from the sample to adhere to the glass plate, and this is the value expressed in weight (mg) of the adhered substance (DIN 75201)
