Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for hard-finishing a flame-retardant curtain base fabric and a flame-retardant treatment method which can be suitably used for a flame-retardant roll curtain or a flame-retardant screen curtain.

[0002]

2. Description of the Related Art Conventionally, polyester fibrous flame-retardant roll curtains, which require moderate hardness, flame retardancy and weather resistance,
As a method of manufacturing a flame-retardant screen curtain, a polyester fabric is subjected to a flame-retardant process with a halogen compound, and then subjected to a hard finish treatment with a polyester resin, a urethane resin, or the like, or a hard finish is applied to a flame-retardant polyester fiber with a polyester resin, a urethane resin, etc. Methods are known.

[0003] However, the former method requires a hard finish after flame-retardant processing, resulting in an increase in cost.
In addition, since a halogen compound is used, there is an environmental problem, and further, there is a problem that weather resistance is poor.

[0004] On the other hand, the latter method using flame-retardant polyester fibers has a fatal defect that a variety of yarns cannot be used to produce a fashion-rich curtain because yarn brands and varieties are limited. The fact is that polyester fiber-based flame-retardant roll curtains and flame-retardant screen curtains which have been satisfactory have not yet been obtained.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the prior art, to provide excellent flame retardancy, feeling, occurrence of chalk marks, light resistance, and the like. Since there is no generation of toxic gas, it is excellent from the viewpoint of environmental protection, and it is possible to provide hard finish simultaneously with flame-retardant processing, and it is low cost and rich in fashionability by using various threads. It is an object of the present invention to provide a method for treating a base fabric for a flame-retardant curtain, which can produce a flame-retardant roll curtain and a flame-retardant screen curtain made of polyester fiber.

[0006]

The present inventors have conducted intensive studies to achieve the above object, and as a result, when a phosphorus-based flame retardant and a phosphinic acid derivative are used in combination, a desired polyester fiber flame-retardant roll curtain, The inventors have found that a flame-retardant screen curtain can be obtained, and arrived at the present invention.

That is, according to the present invention, a compounded liquid containing a phosphinic acid derivative and a phosphorus-based flame retardant represented by the following formula (1) in a weight ratio of 9: 1 to 5: 5 is fixed to a polyester fiber cloth. A method for treating a base fabric for a flame-retardant curtain, characterized in that:

The phosphinic acid derivative can be produced by subjecting a phosphinic acid or a derivative thereof, an aromatic dicarboxylic acid or a lower alkyl ester thereof, and a diol component to a dehydration or dealcoholization reaction by a known method. At that time, the respective molar ratios are not particularly limited. Moreover, the weight average molecular weight of the obtained phosphinic acid derivative is preferably in the range of 500 to 20,000, more preferably in the range of 1,000 to 15,000.

If the above average molecular weight is less than 500, the durability becomes insufficient, while if it exceeds 20,000, the solubility deteriorates, which is not preferable.

The aromatic dicarboxylic acid or lower alkyl ester thereof includes terephthalic acid, isophthalic acid, naphthalenedicarboxylic acid and the like, and the lower alkyl ester includes alkyl esters having 1 to 4 carbon atoms. Can be Particularly preferred are terephthalic acid and its dimethyl ester.

Examples of the diol component include alkylene glycols, polyoxyalkylene glycols, alkylene oxide adducts of alkylene glycols, and alkylene oxide adducts of divalent aromatic hydroxy compounds represented by bisphenol A. Of these, alkylene glycol is particularly preferable, and a linear or branched alkylene glycol having 2 to 10 carbon atoms is more preferable, and ethylene glycol is particularly preferable. These diol components are:
It is also possible to use two or more kinds in combination.

The molecular weight of the diol component is not particularly limited, but it is preferable to use one having a molecular weight of 1,000 or less. If the molecular weight exceeds 1,000, the phosphorus content may decrease, and the flame retardancy may decrease.

The organic solvent used in the above reaction includes
Aromatic hydrocarbons such as toluene, xylene and alkylnaphthalene; ketones such as acetone and methyl ethyl ketone; ethers such as dioxane and ethyl cellosolve; amides such as dimethylformamide; sulfoxides such as dimethyl sulfoxide; methylene chloride; And these organic solvents may be used alone or
It may be used as a mixture of two or more kinds.

In the present invention, a polyester fabric is
A liquid mixture containing the phosphinic acid derivative and the phosphorus-based flame retardant is fixed, and the compounding ratio at this time is 9: 1 to 1: 1.
The ratio is 5: 5, preferably 8: 2 to 6: 4.

If the compounding ratio of the phosphinic acid derivative is larger than the above range, the texture becomes coarse and hard, and chalk marks are easily generated. On the other hand, if the compounding ratio of the phosphinic acid derivative is less than the above range, the composition is too soft to obtain a desired hardness.

As a method of fixing the blended liquid containing the phosphorus-based flame retardant and the phosphinic acid derivative to the polyester fiber, the cloth is immersed in a treatment liquid of a predetermined concentration and then squeezed with a mangle, or the treatment liquid is sprayed onto the cloth. A known method such as coating on the surface can be adopted. After applying the treatment liquid, a dry heat treatment is performed at 100 ° C. or higher, preferably 150 to 180 ° C.

The amount of the phosphorus-based flame retardant and the phosphinic acid derivative fixed to the polyester fabric is 3 to the weight of the fabric.
10 to 10% by weight, preferably 4 to 8% by weight. If the amount of fixation is too small, the flame retardancy becomes poor. On the other hand, if the amount is too large, the texture becomes coarse and hard and chalk marks are generated, which is not preferable.
