Description

  The present invention relates to a laminated sheet having excellent windproof properties, moisture permeability, and prevention of feather loss, a fabric using the same, and a method for producing the same, and more particularly, a windproof property in which a polyurethane meltblown nonwoven fabric is laminated on one side of a nonwoven fabric. The present invention relates to a laminated sheet excellent in moisture permeability and feather slip prevention, a fabric using the same, and a method for producing them.

Due to the diversification of users and the sophistication of merchandise, recent garments are increasingly required to have advanced functions according to their uses. For example, in sports clothes and work clothes worn outdoors, discomfort that keeps sweat away from the skin forever is disliked, and on the other hand, the function of blocking the wind is required to keep the body warm from the cold outside air. ing.
In order to meet such consumer needs, it is desired to provide an outer garment having a function of allowing moisture such as sweat to permeate but blocking the flow of outside air.

As clothing or fabric corresponding to the above-mentioned demands, a product in which a porous film or non-porous film made of polyurethane or the like is inserted between two outer surfaces is put on the market. This product fulfills the above required performance, but it is already in one fixed form, and it is combined with various types of preferred surface fabrics on the market to give it windproof and moisture permeability. It has a drawback that it cannot be used.
Therefore, in order to give windproof and moisture-permeable functions to clothing or fabric, moisture such as sweat can permeate, but fibers with a function that can block the flow of outside air, Simultaneously with the improvement of the fabric itself, there is also a demand for an improvement in the interlining, which can be combined with various types of preferred outer fabrics.

Regarding the above-described interlining, various interlinings have been conventionally used in clothing in order to take advantage of the characteristics of the fabric material and reinforce the weaknesses of the fabric material. As one of these interlinings, there is a so-called adhesive interlining in which an adhesive is attached to one side of a fiber sheet. Since it has the function to provide to, it is used suitably.
The adhesive interlining is widely used for the purpose of imparting shape-retaining properties to clothes, and generally has a configuration in which an adhesive resin for adhering to the outer surface is attached to the interlining base fabric in a predetermined shape. A woven or knitted fabric, a nonwoven fabric, or the like is used as the interlining fabric, and a hot melt resin that can be easily thermally bonded to the outer surface by heating means such as an adhesive press is used as the adhesive resin. The adhesive press is a press that can adjust the temperature, pressure, and time used mainly in a garment factory.
As one of the base materials for these adhesive interlinings, non-woven interlinings are often used as base materials that reinforce materials that are difficult to retain shape retention and provide shape retention. In particular, an adhesive interlining obtained by applying an adhesive to a nonwoven fabric often has an influence on the fabric due to the characteristics of the interlining, and various studies have been made on its selection.

On the other hand, in order to add a cold protection function to clothing or fabric, heat insulation materials such as noodles, synthetic fiber cotton (synthetic cotton), feathers, etc. are provided between the outer fabric, the lining fabric, or between the outer fabric and the lining fabric. It is used. Among them, many feathers that are light and can be stored compactly are used as heat insulating materials.
Feathers are natural heat insulation materials collected from waterfowl breast hair. The feathers have elasticity and soft drape that return to their original bulk even if they are compressed, the inside air escapes and shrinks to a small extent, and when released, the restoring force is greatly increased. Feathers are warm and contain a lot of air when the downhole is cold, and when they are hot, the feathers shrink and easily pass through the air, absorbing sweat. In this way, feathers automatically control temperature and humidity, sense changes, breathe, and are supple. The elastic recovery rate of feathers is about 1.2 times that of synthetic cotton. As described above, the feather is preferably a natural heat insulating material having high moisture retention and repetitive force.

However, if feathers are used as a heat-retaining material, the feathers absorb moisture, release moisture, and diverge. Use a down-proof fabric to prevent the feathers from blowing out from the eyes. Must do so. As for the down proofing process, at least one side of the fabric is crushed and the fabric thread is physically flattened to fill the gap between the warp and weft threads, preventing slippage. Etc. Therefore, the amount of ventilation is very small. In addition, in order to stop the feathers from blowing out, it is necessary to use a fabric with a high density of fabric. Moreover, since the windproof property is calculated | required for the top cloth of the upper garment containing a feather, the thing with the small air flow which is dense is used.
Generally, a down product has a recoverability when it is returned again even if it is stored compactly. However, when the air flow rate is reduced, it is difficult for air inside to escape, so that it is difficult to store the air compactly. Therefore, a product having a suitable air flow rate is required.
Also, if you do not take preventive measures against feather loss, the feathers will blow out to the surface of the fabric while you are wearing it, resulting in a complaint.
In order to solve the above problems, various methods have been proposed (see Patent Documents 1 to 4).
However, sufficient materials are still not found as materials that can impart excellent moisture permeability, windproof properties (breathability), and feather removal prevention properties.

  In view of the above-mentioned problems of the prior art, the object of the present invention is to have both moisture permeability, windproof property and anti-feathering property, and to be bonded to other fabrics and other substrates by a simple heat press.

The polyurethane melt-blown nonwoven fabric (B) used in the laminated sheet of the present invention is generally a nonwoven fabric formed by a melt-blowing method using polyurethane having excellent stretch performance and recovery performance. This thermoplastic polyurethane is melt-spun by a melt blow method to form a stretchable nonwoven fabric. This non-woven fabric is used because it is rich in stretchability and flexibility as compared with other non-woven fabrics and has sufficient air permeability.
Polyurethane is produced by polymerizing a high molecular weight polyol compound that forms a soft segment portion, a low molecular weight diol compound that forms a hard segment, and an organic diisocyanate compound.

On the other hand, when it exceeds 50 g / m ² , the air permeability and moisture permeability are hindered and the texture becomes hard. By setting the amount of lamination within this range, it is possible to provide a laminated sheet or interlining having a suitable windproof property (or air permeability), excellent moisture permeability and prevention of feather removal.
In addition, additives such as a heat-resistant agent, an ultraviolet absorber, and a flame retardant may be appropriately present in the fibers constituting the base fabric (A) such as the nonwoven fabric and the melt-blown nonwoven fabric (B) made of polyurethane.

3. Hot melt adhesive (C, C ')
The laminated sheet of the present invention is a laminated sheet obtained by sequentially laminating the above-mentioned polyurethane melt-blown nonwoven fabric (B) and hot melt adhesive (C) on one side of a base fabric (A) such as a nonwoven fabric, and preferred embodiments thereof.

In these, the method of apply | coating an adhesive to a dot form not in the whole surface but a non-entire state is preferable, and base fabric (A), such as a nonwoven fabric, and a polyurethane by the hot-melt-adhesive adhered to the dot form The melt blown nonwoven fabric (B) or the polyurethane melt blown nonwoven fabric (B) and the surface fabric are integrated by point joining. By this point joining, it is possible to avoid excessive speeding up of the surface movement, curing of the adhesive, deterioration of texture, and deterioration of moisture permeability. In particular, when the adhesive is laminated in a non-overall state, there is an effect that the moisture permeability is not lowered as the whole laminated sheet.

When adhering the adhesive in dots, the adhesive is placed in dots at an appropriate density interval so as not to impair the texture and stretch recovery of the outer material, and evenly placed on any part of the nonwoven fabric It is preferable that the arrangement density of the dots and the size of one dot are a base fabric (A) such as a non-woven fabric and a polyurethane melt-blown non-woven fabric (B) so as not to impair the texture and stretch recovery of the outer material. Alternatively, it is appropriately selected so that the melt blown nonwoven fabric (B) made of polyurethane and the surface fabric are bonded and integrated.
For example, in one side of the base fabric (A) or the polyurethane melt-blown nonwoven fabric (B), the diameter of each dot is preferably 0.1 to 3.0 mm, and the base fabric (A) surface or the polyurethane melt-blown nonwoven fabric is preferable. (B) The density of dots on the surface is preferably 50 to 1,500 / in ² , and the amount of dots attached to the base fabric (A) surface or the polyurethane melt-blown nonwoven fabric (B) surface is 2 to 60 g / m ² is preferred. If the dot diameter, density, and adhesion amount are less than this range, for example, good adhesion strength to the outer surface is not guaranteed, and if it exceeds this range, it will ooze out on the back surface during adhesion heating and pressurization, and the appearance texture will be impaired.
When the adhesive is adhered to the polyurethane melt-blown nonwoven fabric (B), the diameter, density, and adhesion amount can be adjusted in accordance with the surface material to be adhered within the above-mentioned range, as described above.

  There are no particular limitations on the adhesive dot-shaped coating method, and for example, a dispersion dot coating method, a powder dot coating method, a double dot coating method, or the like can be used. Moreover, it does not specifically limit as a dot-like adhesion pattern, For example, a random pattern, a lattice-like pattern (or regular pattern), etc. can be mentioned. These patterns can be used properly according to the application, the thickness of the outer fabric, the texture and the like.

  In the present invention, a hot melt adhesive (C, C ′) is used. The hot melt adhesive is not particularly limited as long as it melts at 100 to 150 ° C. and exhibits an adhesive function. Examples of the material include polyamide, polyester, polyurethane, polyethylene, and ethylene-acetic acid.

Next, the laminated sheets A, B, C, D, E, F, and G obtained in Examples 1 to 5 and Comparative Examples 1 and 2 were used as the interlining, and the outer surface (cotton) on the hot melt adhesive side. 100% Tendon, Soaron, Wool Gabba, T / C Broad) and surface bonding conditions: heat press machine (JR600) 130 ° C. × 6.9 N / cm × 10 sec. Peel strength (cN / 2.5 cm width) after washing (conditions: washing 10 minutes, rinsing 3 minutes × 2 times, dehydration 1 minute) 5 times, after Parkren commercial dry 3 times, and petroleum-based commercial dry 3 times ) Was measured and the adhesion was evaluated. Moreover, air permeability and moisture permeability were also evaluated. Furthermore, the texture, sound, and weight of the fabric were also evaluated in three stages: good (◯), normal (Δ), and bad (×). The evaluation results are shown in Table 1 together with the physical property evaluation of the laminated sheet alone.

In addition, the laminated sheet obtained in Example 3 was used as a feather detachment prevention, and on the hot melt adhesive side, the surface material (tengu, wool gab) and the surface material adhesion condition: hot press machine (JR600) 130 ° C. × 6.9 N Adhesive integration was performed at / cm × 10 sec, and feather removal evaluation was performed.
The evaluation results are also shown in Table 1.

As is clear from Table 1, the adhesive evaluation is good in all of Examples 1 to 5 after initial, after washing, and after drying, as compared with the film adhesive products of Comparative Examples 1 and 2.
In addition, the laminated sheets of Examples 1 to 5 have an air permeability of almost 10 cc or less after bonding to the outer fabric, and can be said to be windproof, and the moisture permeability is as good as 7000 g / m ² · 24 h or more. Value.
Regarding the sound of sensory evaluation, Comparative Examples 1 and 2 sound unique to the film, but Examples 1 to 5 do not sound. Moreover, about the texture, the type of Example 2 is softer.
Furthermore, from the feather drop test, the laminated sheet of Example 3 is within the usage range.
As a result, it is clear that the laminated sheet of the present invention has suitable windproof properties (or breathability), excellent moisture permeability, and prevention of feather loss, and can be suitably used as a functional interlining. .

  Since the laminated sheet of the present invention has suitable windproof properties (or breathability), excellent moisture permeability, and prevention of feather slippage, fabrics and clothes that require moisture permeability are suitable, and various uses are also possible. Also widely applicable.
