The present invention relates to fabrics and protective products that are not only flame-retardant but also breathable and waterproof, windproof and comfortable to wear.

Conventionally, as a woven fabric having excellent waterproof and windproof properties, a coated product in which a resin is applied to a surface layer portion, a laminated product of a film, and the like have been proposed (see, for example, Patent Documents 1 to 4). Further, there have been proposed coating products using flame-retardant fibers and a coating product in which a resin is applied to a surface layer portion for the purpose of moisture permeability and waterproofness, a laminated product of a film, and the like (see, for example, Patent Documents 5 and 6).

Further, there is a problem that the heat resistance is insufficient and a problem that the texture becomes hard and the weight becomes heavy.

As the coagulation bath used for obtaining the fiber, an amide-based solvent, preferably an aqueous solution having an NMP concentration of 45 to 60% by mass, which does not substantially contain an inorganic salt, is used in a bath solution temperature range of 10 to 50 ° C. Use. If the concentration of the amide solvent (preferably NMP) is less than 45% by mass, the skin has a thick structure, the cleaning efficiency in the cleaning step is lowered, and it becomes difficult to reduce the residual solvent amount of the fiber. On the other hand, when the concentration of the amide solvent (preferably NMP) exceeds 60% by mass, uniform coagulation cannot be performed up to the inside of the fiber, and therefore the amount of residual solvent in the fiber is also reduced. Becomes difficult. The time for immersing the fiber in the coagulation bath is appropriately in the range of 0.1 to 30 seconds.

Subsequently, an amide-based solvent, preferably an aqueous solution having an NMP concentration of 45 to 60% by mass, was placed in a plastic stretching bath in which the temperature of the bath solution was in the range of 10 to 50 ° C., at a stretching ratio of 3 to 4 times.

In particular, short fibers having a fiber length of 25 to 200 mm (more preferably 30 to 150 mm) are preferable for blending with other fibers.

Further, the type of the spun yarn is not limited, and may be any of innovative spinning such as MTS, MJS, MVS, air jet spun yarn, ring spun yarn, core-sheath two-layer structure spun yarn, core span yarn, cut-off yarn and the like. .. At that time, the fiber length of each fiber is preferably 25 to 200 mm (more preferably 30 to 150 mm).

The twisting direction may be either the Z direction or the S direction.
Twist coefficient = number of twists (times / 2.54 cm) / cotton count of spun yarn (Ecc) ^1/2

Next, a twist-preventing set (vacuum steam set) is applied to the spun yarn as needed, and then two or more spun yarns (preferably 2 to 4, particularly preferably two) are pulled together and combined. Twist. Examples of the twisting machine used for the combined twist include a twisting machine such as an up twister, a covering machine, an Italian twisting machine, and a double twister.

At that time, the twisting direction of the combined twist (upper twist) may be the additional twisting direction or the reverse twisting direction. The number of twists is preferably 500 times / m or more, more preferably 700 to 3000 times / m, and particularly preferably 900 to 2000 times / m. If the number of twists is less than 500 times / m, the shape of the spun yarn may not be coiled after the anti-twist set and untwisting. Further, when the number of twists is 3000 times / m or more, the untwisting torque is high even if the anti-twist set is applied, and there is a possibility that there is a problem in workability when weaving the woven fabric in the next step.

Next, the twist-preventing set (high-pressure vacuum steam set similar to the conventional aramid twin-thread anti-twisting set) is applied to the combined twisted yarn. If it is necessary to provide a strong anti-twist set, the number of anti-twist sets may be increased, or the temperature and set time of the anti-twist set may be changed. For example, the set temperature may be 60 to 125 ° C., the set time may be 20 to 40 minutes, and the number of times may be 1 to 3 times. However, the higher the set temperature and the longer the set time, the better the settability is preferable. It is possible to improve the setability by increasing the number of anti-twist sets, lengthening the processing time, and raising the temperature, but production control (safety of work control, quality control, etc.) and production processing Considering the cost, it is preferable to increase the processing time. Further, the higher the degree of vacuum, the better the quality, which is preferable.

In some cases, it is possible to omit the scouring and relaxing steps.

In particular, in the present invention, it is preferable to apply a water-repellent treatment to the fabric. Here, the water repellent may be a fluorine-based water repellent or a non-fluorine-based water repellent such as a hydrocarbon-based compound or a silicone-based compound. If necessary, an antistatic agent, a melamine resin, and a catalyst are mixed to make a processing agent having a water repellent concentration of about 3 to 15% by weight, a pickup rate of about 50 to 90%, and a woven fabric using the processing agent. It is preferable to treat the surface of. Examples of the method for treating the surface of the woven fabric with the processing agent include a pad method and a spray method. Of these, the pad method is preferable for allowing the processing agent to penetrate into the inside of the woven fabric. The pickup rate is the weight ratio (%) of the processing agent to the weight of the woven fabric (before the processing agent is applied).

Further, when the woven fabric is heat-pressurized (calendar processing) in at least one of the pre-process and the post-process of the water-repellent processing step, the surface of the woven fabric tends to be in the shape of lotus leaves, which is excellent in repellency.
