However, it is difficult to say that the conventional sock filter has a small amount of air supplied from the sock filter and exhibits a sufficient effect as air conditioning. Therefore, the present inventors also examined a method of increasing the air permeability of the sheet-like material that constitutes the tubular body used for the sock filter in order to increase the air volume, but the sock filter is hung along the ceiling. It is installed like this and inflates with the air sent from the air conditioner, but if the air permeability is increased, it will not expand unless a large amount of air is sent in, it will not spoil the aesthetics of the sock filter and the air blower noise of the air conditioner will be large. Had the problem of becoming.

Further, when the airflow is reduced when it is not desired to send out a large amount of air from the air conditioner, or when the air conditioner is stopped, the sock filter is shrunk, and there is a problem in its design.
Therefore, the inventors of the present invention have an object to provide a sock duct capable of supplying a sufficient amount of air to a room for such a sock filter and having excellent design.

(Example 1)
Anti-fungal agent: Nikkanon AFN (organic sulfur compound, Nika Kagaku, active ingredient 20%) 1% against plain weave (made of polyester), flame retardant: Nikkafinen CG-1 (bromine compound, Nika Kagaku, active ingredient 42%) 10%, antibacterial agent: Nikkanon RB (quaternary ammonium salt, Nichika Kagaku, active ingredient 15%) 1% by weight, anti-allergic agent (poly-made by Aldrich) Aqueous dispersion containing 10% of 4-vinylphenol (30% by weight average molecular weight of 8000) and 10% of antistatic agent: Nicepol FE26 (nonionic polymer compound, Nichika Chemical Co., Ltd., active ingredient 21%). Was applied by the padding method, dried at 120° C. for 30 seconds, and then heat set at 160° C. for 30 seconds. The air permeability of this sheet material was 19.8 cm3/cm2·s. Further, the density was vertical×horizontal=109 lines/2.54 cm×91 lines/2.54 cm.

Next, this sheet-like material was cut into a length of 7 m and a width of 1.4 m, and was folded in two in the width direction to have a length of 7 m and a width of 0.7 m. The two sides (the long sides of 7 m and the short sides of 0.7 m) that have been overlapped with each other are stuck together using a hot-melt double-sided adhesive tape, and one end is closed and the other end is An open tubular body was obtained. In addition, the portion where the lengthwise direction of the tubular body was bonded using the double-sided adhesive tape was used as the hanging portion 5 for connecting with a hook or chain when the sock filter is suspended on the ceiling.

Next, this tubular body was folded back by 3 mm so that concave portions 3 and convex portions 4 were alternately formed in the lengthwise direction, and then pleated (200° C.) in a pattern of folding back by 4 mm. The sock filter shown in 1 was obtained.
The performance of the obtained sock filter is shown in Table 1.

(Examples 2 and 3)
In Examples 2 and 3, the length of 7 m, the width of 0.7 m, and the two sides obtained in Example 1 were overlapped with a hot-melt double-sided adhesive tape. The short side thereof was bonded together, one end was closed, and the other end was open.
This tubular body was bent to form the bending line 6 shown in FIGS. 2 and 3. Next, in this bent state, pleating (200° C.) was performed in a pattern of folding back by 5 mm so that the concave portions 3 and the convex portions 4 were alternately formed, and the sock filter shown in FIGS. 2 and 3 was obtained. ..
The performance of the obtained sock filter is shown in Table 1.

(Example 4)
A shrinkable resin was applied to the sheet-like material of Example 1 so that a portion where the resin was not applied had a circular shape of 10 cm, and heat treatment was performed to shrink the recessed portion 3 and the circular portion The convex portion 4 is formed.
Next, this sheet-shaped material was cut into a length of 7 m and a width of 1.4 m, and was folded in two in the width direction to have a length of 7 m and a width of 0.7 m. The two sides (7 m long sides and 0.7 m short sides) that are overlapped are respectively bonded using a hot-melt double-sided adhesive tape, one end is closed, and the other end is closed. The sock filter 1 shown in FIG. 4 was obtained by using the opened cylindrical body 2. In addition, the portion where the lengthwise direction of the tubular body was adhered using the double-sided adhesive tape was used as the suspending portion 5 for connecting with a hook or chain when suspending the sock filter on the ceiling.

The sock filter of the present Example 4 has a length of 7 meters in order to obtain a tubular body after giving unevenness to the sheet-like material, but the sheet-like material is shortened by 5% before and after giving unevenness. It was The height difference between the concave portion and the convex portion was 5 mm. Air permeability, the portion is shrunk, which had decreased from 17.3cm ³ / cm ² · s and 19.8cm ³ / cm ² · s was applied to the convex portion, mixed portions of the projections 4 and the recesses 3 Was as high as 21.4 cm ³ /cm ² ·s. This is presumed to be due to the fact that the surface of the sample of a predetermined size has irregularities on the measurement, and the substantial measurement area increases.
In addition, antibacterial properties pass antibacterial deodorant properties and bacteriostatic properties, flame retardancy is good in both microburner method and coil method, and allergen suppression effect is "1" for evaluation (1) and "2" for evaluation (2). -" was a good result.

The sock filters of Examples 1 to 4 obtained as described above have irregularities on the surface of the tubular body and have an increased surface area, so mild air unique to the sock filter can be provided indoors, and A large amount can be supplied indoors, providing excellent air conditioning effects. Moreover, it has various three-dimensional patterns and is excellent in design.
In particular, those using polyester fiber are excellent in the durability of the three-dimensional pattern, and can maintain the three-dimensional pattern even when exposed to warm air for a long time. Further, it is possible to provide a sock filter which is excellent in antibacterial property, flame retardancy, allergen suppressing effect, antifungal property and antistatic property.
In addition, the unblocked ends of the sock filters of Examples 1, 2, and 3 were connected to the air outlets of the air conditioner, respectively, and the suspension part 5 of the tubular body and the ceiling were connected at 10 places and suspended by chains. When the air conditioner was operated and the sock filter was inflated, the pleats spread and each had excellent designability. The height difference of the irregularities formed on the surface of the tubular body 2 was about 1 mm.

In addition, the non-closed end of the sock filter of Example 4 was connected to the air outlet of the air conditioner, and the hanging part 5 of the tubular body and the ceiling were connected at 10 places by chains to hang the air conditioner. When the sock filter was operated and inflated, the circular portion formed the convex portion 4 and had excellent designability. The height difference of the irregularities formed on the surface of the tubular body 2 was about 5 mm.

Further, if the portion where the sock filter 1 described in Example 1 is suspended is a movable curtain rail, when the air blow from the air conditioner is stopped, the sock filter 1 contracts in the length direction and becomes a tubular body. The unevenness of the formed pleats appears more clearly, the design characteristics change, and you can enjoy designs with different ceilings. In addition, the hanging portion of the sock filter is used as a movable curtain rail, and a string-like elastic body such as rubber is attached to the end of the sock filter in the length direction so that tension is applied from the air conditioner side. When the air conditioner is stopped, the sock filter can be installed by attaching it to the section or by using a composite of fibers having elasticity such as urethane in addition to polyester fiber as the material in the longitudinal direction forming the tubular body. It is also possible to have a structure in which the sock filter is greatly contracted in the length direction and the sock filter is housed near the ceiling of the wall surface.
