BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below. The float cover of the present invention is made of a fabric woven and knitted with polyester primary yarn. Polyester terephthalate is preferably used as the polyester resin forming the polyester spun yarn, and a small amount of a copolymerization component, a heat-resistant agent and other additives may be included.

The intrinsic viscosity of the polyester resin is
It is necessary to be 0.85 or more, and 0.67 to 1.
20 is preferable. Here, the intrinsic viscosity means a value measured at a temperature of 20 ° C. using a mixture of phenol and tetrachloroethane at a mass ratio of 1: 1 as a measurement solvent. If the intrinsic viscosity is less than 0.85, the draw ratio must be extremely increased in order to provide the polyester spun yarn with the strength required as a constituent material of the float cover, especially the float cover of the antifouling film. However, the operability during the production of the spun-dyed yarn is deteriorated and the quality of the obtained spun-dyed yarn is also deteriorated, which is not preferable.

Further, the polyester-dyed yarn must contain a pigment. The weathering resistance is inferior when the dyed yarn is dyed without a pigment. The hue of the spun yarn is preferably yellow or orange so that it can be easily seen from a ship or the like. Therefore, the pigment is preferably a yellow pigment or an orange pigment. The yellow pigment is preferably a color pigment mainly composed of anthraquin yellow and perinone red, and the orange pigment is anthraquinone yellow.
Coloring pigments based on perinone red and anthraquinone tea are preferred. As a method of incorporating the above-mentioned pigment into the spun-dyed yarn, the pigment may be added to the chip in the process of producing the spun-dyed yarn, or a pigment master chip may be used.

There is no particular limitation on the structure structure of the above-mentioned cloth woven or knitted with the polyester original yarn (hereinafter referred to as polyester original cloth), and it may be a woven structure or a knit structure, but the strength is ensured. A plain weave, a twill weave, a satin weave, or a woven fabric structure obtained by changing these fabrics is preferable from the standpoint of ease.

Since the polyester original cloth should have strength suitable for the float cover, the tensile strength of the polyester original cloth should be 2 kN / 3 cm or more, and 2 kN / 3 cm. -10kN / 3cm
Is preferred. Usually, the float cover is used by being connected to a floated object such as a pollution prevention film.When the floated object is subjected to a force due to the influence of waves or the like, the float cover connected to the float cover is pulled and the float cover is pulled. The buoyancy resistance causes a strong force on the fabric. At this time, if the tensile strength is less than 2 kN / 3 cm, the float cover may be damaged. On the other hand, regarding the upper limit of the tensile strength, it can be said that the stronger the strength alone is, the better.However, increasing the tensile strength more than necessary leads to extremely high yarn fineness and weaving density. It is not preferable because the weight increases and the cost increases. From this point, it is preferable that the tensile strength does not exceed 10 kN / 3 cm. The fabric weight is 1200 g /
It is preferably m 2 or less.

The float cover of the present invention is obtained by appropriately sewing the above-mentioned polyester swatch cloth so as to have a tubular shape or a bag shape when used. An example of the form and the mode of use will be described with reference to FIGS. 1 and 2. For example, in order to include a cylindrical float, a float cover 1 which can preferably form a cylinder opening along the longitudinal direction. Is connected to an object to be floated such as a pollution prevention film.
Then, the float 2 is enclosed in the float cover, and the opening is taken in and tied with the rope 7 for use. In order to connect the floats to each other and to stabilize the float in the float cover, it is preferable to pass an intermediate rope through the float.

The layer structure of the float cover of the present invention may be a layer structure composed only of the above-mentioned polyester original cloth, or may be a multilayer structure composed of other cloth or sheet material. Since the above polyester primary cloth has water permeability, when the float cover is composed of only the layer of the above polyester original cloth, or when it has a multi-layer structure with another material having water permeability, Since water does not stay inside the float cover and is frequently replaced with the outside, it is possible to avoid a situation in which water rots inside the float cover.

Example 1 Polyethylene terephthalate (PET) having an intrinsic viscosity of 1.11.
Anthraquinone yellow on the same PET resin as the resin chip,
A master chip containing 20 mass% of an orange coloring pigment mainly composed of perinone red and anthraquinone tea,
PET resin chip / master chip = 97.5 / 2.5 melt-mixed as raw material, spinning temperature 295 ℃, spun from a spinneret with 96 holes, and a length of 2 just below the spinneret.
After passing through a heating cylinder of 10 mm and an atmospheric temperature of 430 ° C., cooling air was blown to cool it. The spinning speed was 350 m after the spinning oil was added to the cooled and solidified yarn in an amount of 0.7% by mass of the fiber mass.
/ Min take-up roller to give a 0.5% stretch between the take-up roller and the feed roller to stabilize the yarn, while blowing superheated steam between the feed roller and the heated drawing roller at 230 ° C. Stretching 6.0 times, take it up with a heating roller at the same speed as the stretching roller at 150 ° C, add 0.7% by mass of finishing oil to the fiber mass, and wind it up.
An orange dyed yarn of 5cN / dtex, 21% elongation and 1100dtex / 96f was obtained. The warp and weft yarns obtained by twisting three of these spun yarns at 80 T / m in the s direction were used by a rapier loom to have a weave design of 2/2 weave and a weave density of 25 warp / 2.54 c
A woven fabric having m, 25 wefts / 2.54 cm, and a cloth width of 210 cm was woven. The tensile strength of this fabric is 5.6kN / 3cm in the warp direction,
The weft direction was 5.5 kN / 3 cm. A tubular float cover was prepared using this woven fabric and sewn to the curtain portion of the pollution prevention membrane unit (20 m / 1 span) as shown in FIG. Thereafter, a tubular float made of expanded polystyrene was included in the float cover, the pollution prevention membrane unit was installed in the sea, and the curtain was used for two years in a state of being vertically floated from the seabed. After use, there was no tear on the float cover, and it was still in good condition. The product was incinerated, but no harmful gas was generated.
