Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a polyester fiber product and a method for producing the same, and its objective is flame retardancy.

It is an object of the present invention to provide a polyester fiber product having a good texture and excellent durability.

<Prior art> Conventionally, halogenated phosphate esters have been used as flame retardants for post-processing of polyester fibers.

These include cyclic phosphate esters and halogenated cycloalkane compounds (Japanese Patent Application Laid-open No. 137377/1983). The disadvantages of halogenated phosphate esters and cyclic phosphate ester compounds are that they are both in liquid form, so when applied to dyed fabrics, the color fastness to friction may be affected, or color migration may occur over time, resulting in hot water contamination. This is difficult to apply to cloth.

Furthermore, due to its low flame retardant effect, flame retardant properties can only be imparted to lace curtains with a small fabric weight and plain pattern, which limits their use. On the other hand, halogenated cycloalkane compounds have relatively good flame retardant properties and can also be used for ordinary lace curtains and drape curtains. However, recently there has been a strong demand for curtains to be diversified, sophisticated, and have multiple functions, and in particular, halogenated cycloalkane compounds are being used for curtains using black dope-dyed yarn, curtains using designed yarn, and raised curtains. However, there are some materials whose flame retardant properties are insufficient, so it is necessary to further improve their flame retardant properties. As a result of intensive studies in view of these points, the present inventors have found that the combined use of a halogenated cycloalkane compound and a specific phosphinate compound or phosphonate compound in a polyester fabric has an unexpected mutual effect. The present invention was achieved by discovering that the compound exhibits excellent flame retardant properties.

<Objective of the Invention> In other words, the object of the present invention is to provide a polyester fiber product which is difficult to make flameproof, and at the same time provides flameproofing with sufficient flameproofing properties and excellent texture, fastness, etc. Our goal is to provide flexible polyester fiber products.

<Configuration of the Invention> The configuration of the present invention for achieving the above object is as follows.

(8) The method for producing a polyester fiber product according to claim (6), wherein the dispersion of compound (A) and the dispersion of compound (B) are separately treated.

The cycloalkane compound used as a flame retardant in the present invention refers to a cycloalkane compound having 7 to 12 ring carbon atoms and 3 to 6 halogen atoms bonded to the carbon atoms. especially those with a melting point of 140~
A temperature of 190° C. is preferable, and as described later, the average particle size is preferably 1 micron or less.

A particularly preferable example is 1+z+5+6+ i9.1
0-herzabromocyclododecante.

In addition, examples of the phosphinate compound or phosphonate compound (Bl) represented by the above general formula include the following.
and (Bl can be attached to polyester fibers by batting, spraying, or coating a polyester fiber product with an aqueous dispersion or a solution of the flame retardant compounds (A) and (B) dissolved in an organic solvent. The second digit changes.Also, as a special method, for example, 10
Another effective method is to treat polyester fibers with an aqueous dispersion at 0° C. so that flame retardant compounds) and (B) are adsorbed onto the fibers. After the flame retardant compound and CB+ are attached to polyester fibers, they are heat-treated at a temperature of 120 to 240°C.

The treatment may be performed at any stage after spinning.
For example, it may be carried out before or after stretching, or before or after producing a knitted fabric or other sheet-like object.

The dispersion of the flame retardant compounds (A) and (B) can be prepared by using a ball mill, a sand grinder, and pulverizing the flame retardant compounds to an average particle diameter of 1 micron or less.

When the average particle size is 1 micron or less, a dispersion aid is not necessarily required.

The adhesion ratio of the halogenated isochloroalkane compound (A) and the phosphinate or phosphonate compound (nl is 30 to 95% by weight in the ratio of the former to 95% by weight.

The latter is preferably 70 to 5% by weight.

If the ratio of both is outside this range, the mutual effect will not be sufficiently exhibited. Further, the adhesion rate of the flame retardant compounds (A) and (B) to the textile product is about 1 to 8% by weight. If the adhesion rate is less than about 1% by weight, it is difficult to impart sufficient flame retardant properties to textile products (on the other hand, even if the adhesion rate exceeds 8 rL, these properties do not improve significantly and are uneconomical; "Bl love" that worsens the texture, feel, etc. of itself.

In addition, the flame retardant compounds (N and (Bl) may be used as a mixed dispersion, or each may be used as a separate dispersion, and
``The treatment may be performed with the dispersion liquid and then the (n) dispersion liquid, or the treatment may be performed in the reverse order.
