Description

  The present invention relates to a cloth for clothing excellent in bending flexibility, compression flexibility, heat retention, antistatic properties, and moisture absorption and desorption, and a clothing product using the same.

In recent years, the demand for comfort has increased in the fabric for clothing, and not only the functionality such as durability and handleability but also the comfort at the time of wearing or use, that is, the so-called human sensitivity is required.
Conventionally, in order to ensure the heat-retaining property of the cloth for clothing, a synthetic cotton medium is used, and the middle cotton made of synthetic short fibers such as polyester and polyamide has a good balance of mechanical performance. Widely used for clothing such as down jackets.
The properties required for the middle cotton include bending flexibility, compression flexibility, heat retention, antistatic properties, moisture absorption / release properties, but the synthetic short fibers used in conventional middle cotton have a cross-sectional shape. In general, it has a round cross section, and the single yarn itself is not flexible enough, and the gap between fibers is large. In addition to not being able to obtain a feeling, the feeling of stuffiness was felt, and static electricity was generated due to friction with the inner garment.

In order to improve the above-mentioned defect of the inside cotton, it is a fiber in which two components that are incompatible with each other are blended, and has 300 or more voids inside the fiber, and the average diameter of the voids is 0.00. It is characterized by using void fibers having an inclined structure in which the number of voids is 1.3 times or more distributed in the inner layer portion with respect to the outer layer portion of the fiber, and the cross-sectional shape includes an irregular cross section. Medium cotton has been proposed (see Patent Document 1). Certainly, since polyester fibers having a large number of fine voids are used, the heat retention and the like are slightly improved, but they still do not have satisfactory heat retention, and are indispensable for clothing use together with it, High functionality related to human physiology and sensibility such as bending flexibility, compression flexibility, antistatic and moisture absorption / release properties is extremely inferior, and clothing using this cotton is not comfortable to wear, urethane-like It would be a low-grade clothing product.
Providing a fabric for clothing that can improve the bending flexibility, compression flexibility, heat retention, antistatic properties, moisture absorption and desorption properties by improving the above-mentioned drawbacks of cotton and compatibility with the outer surface. Is desired.

It becomes a fabric. From the above, the fabric of the present invention is suitably used for clothing applications such as quilting jackets, down jackets, and cold clothes.

Hereinafter, the present invention will be described in detail.
The inside cotton used in the present invention comprises a polyester short fiber (hereinafter referred to as A), a regenerated cellulose short fiber (hereinafter referred to as B), and a synthetic short fiber (hereinafter referred to as C) having a W-shaped cross section. Included).
Short fiber made of polyester polymer having fiber-forming properties, such as homopolymers such as polyethylene terephthalate, polybutylene terephthalate, polytrimethylene terephthalate, and polyester copolymers with these polymers Is used. There may be no problem even if additives such as antistatic agents, flame retardants, heat-resistant agents, light-proofing agents, and titanium oxide are added to the short fibers. From the viewpoint of strength, rigidity and durability, polyethylene terephthalate is preferable.

  The constituent fiber B of the middle cotton material is a cellulose-based regenerated fiber, and short fibers such as copper ammonia rayon, viscose rayon (including strong rayon, polynosic rayon, high wet modulus rayon), and purified cellulose (lyocell) are used. It is done. Although not particularly limited, copper ammonia rayon fiber is more preferable in order to remarkably improve the bending flexibility and compression flexibility of the inside cotton of the present invention. Specifically, Asahi Kasei Fibers Co., Ltd. ) Cupra (Bemberg R). When the short fiber of the cellulose-based regenerated fiber is other than copper ammonia rayon, the bending stress of the regenerated cellulose-based short fiber itself is slightly increased, and the bending flexibility and compression flexibility of the cotton tend to be reduced.

  The constituent fiber C of the inner cotton material is not particularly limited as long as it is a synthetic short fiber such as a polyester fiber, a polyamide fiber, a polyacrylonitrile fiber, a polyvinyl fiber, a polypropylene fiber, and a polyurethane fiber. The cross-sectional shape of the single yarn is not particularly limited, and may be round, W, triangular, pentagonal, star, L, T, Y, H, π, +, # , * -Type, Yaba-type, dog-bone type, etc., and these hollow cross-sectional shapes.

In the present invention, the mixing weight ratio of the inner constituent fibers is A: B: C = (10% to 40%) :( 10% to 40%) :( 20% to 80%), more preferably. , A: B: C = (
15% to 35%): (15% to 35%): (30% to 70%), more preferably A: B: C = (20% to 30%): (20% to 30%) :( 40% to 60%).
When the mixing weight ratio of A and B is less than 10%, bending flexibility, compression flexibility, or antistatic property tends to be lowered. Furthermore, heat retention or moisture absorption / release properties are slightly reduced. When the mixing weight ratio of A or B exceeds 40%, there is no problem with antistatic properties and moisture absorption / release properties, but bending flexibility and compression flexibility tend to decrease, and heat retention tends to decrease.

  The fiber filling rate of the middle cotton material refers to the proportion of fibers in a unit volume. The fiber filling rate is preferably 0.6% to 5%. More preferably, they are 0.7%-4%, More preferably, they are 0.8%-3%. When the fiber filling rate is less than 0.6%, the heat retention is slightly lowered. In addition, in clothing such as quilted jackets, down jackets, and winter clothes that use such cotton, the compression recovery of the cotton has a tendency to decline, and a silhouette with an appropriate swelling cannot be obtained and worn for a long time. If this is the case, the appearance quality will be reduced, there will be no durability for washing such as repeated home washing and dry cleaning, and the form stability will be poor. If the fiber filling rate of the inner cotton exceeds 5%, the air flow becomes poor, and heat and moisture generated from the body are accumulated, resulting in discomfort. The fiber filling rate of the middle cotton material being 0.6% to 5% means that the porosity of the air layer is 95 to 99.4%. In the present invention, the porosity of the middle cotton material is High is an important characteristic.

The degree of irregularity in the A fiber refers to a value obtained by drawing a rectangle circumscribing the W-shaped cross section and dividing the long side L by the short side H. It is preferable that the variant degree of A is 2 to 4, more preferably 2.5 to 3.5, and still more preferably 2.8 to 3.3.
If the degree of profile is less than 2, the bending stress of A becomes large, the bending flexibility and compression flexibility of the inner cotton are lowered, and the flexibility and softness cannot be obtained, and the fiber filling rate is 0.6. %, It becomes difficult to obtain sufficient heat retention.

  When the degree of profile exceeds 4, the gap between the single yarns becomes extremely small, and it is difficult to obtain a feeling of swelling and heat retention when the inside yarn is used. Further, when the fiber filling rate exceeds 5%, the void ratio in the inside cotton is lowered, the air flow tends to be poor, and heat and moisture generated from the body tend to be accumulated and uncomfortable. In addition, the opening angle of the W-shaped cross section is expressed as an angle when a line drawn from both ends of the lower concave portion of the W-shaped cross-sectional yarn is drawn, and means a sharp difference in the W-shaped cross-sectional shape. Become. In the present invention, the opening angle of the W-shaped cross section is preferably in the range of 110 to 150 degrees, more preferably 120 to 140 degrees.

  In the present invention, the bending resistance of the inner cotton refers to the degree of rigidity. The bending resistance of the middle cotton is preferably 65 mm or less, more preferably 63 mm or less, and still more preferably 60 mm or less. When the bending resistance exceeds 65 mm, the feeling of restraint during operation during wearing is large, so that it is difficult to move, and the fit to the body is inferior, resulting in poor comfort. When the bending resistance of the inner cotton is within this range, the cloth for clothing has sufficient flexibility and flexibility, and the follow-up performance is improved, and the fit to the body is excellent.

  The compression rigidity of the middle cotton material refers to the degree of ease of compression when the middle cotton is compressed in the thickness direction. The compression rigidity is preferably 0.7 or less, more preferably 0.6 or less. When the compression rigidity is 0.7 or less, a good compression softness can be obtained when wearing a garment using a middle cotton, and the middle cotton is compressed with an appropriate amount of deformation. You can experience the comfort of sleeping. When the compression rigidity exceeds 0.7, the inner cotton is not compressed at the time of wearing, and uncomfortable feeling such as feeling of wobbling or restraining the movement of the body is remarkable, and the compression flexibility becomes insufficient. When the compression rigidity of the middle cotton is within this range, the cloth for clothing has sufficient compression rigidity, so that a comfortable wearing feeling and sleeping comfort can be experienced.

The half-life of the middle cotton material is the time from when a voltage of 10 kV is applied for 30 seconds until the charged voltage decays to one half of the initial charged voltage. In the middle cotton of the present invention, the half-life of the charged voltage is preferably 30 seconds or less, more preferably 20 seconds or less, still more preferably 17 seconds or less. If the half-life exceeds 30 seconds, for example, in the case of clothing, static electricity is generated due to friction with the inner garment, resulting in poor comfort, and dust and pollen are likely to adhere, and dirt on the clothing is noticeable. It can also cause hay fever. When the half-life of the middle cotton is within this range, the cloth for clothing has sufficient antistatic properties, and a comfortable wearing feeling and a dust adhesion preventing effect can be experienced.

The woven fabric in the present invention preferably has an air permeability of 10 to 100 cc / cm ² / sec, more preferably 20 to 90 cc / cm ² / sec, and still more preferably 30 to 80 cc / cm ² / sec. When the air permeability is lower than 10 cc / cm ² / sec, a sufficient ventilation effect cannot be obtained, and therefore heat and water vapor emitted from the body are accumulated, and it is difficult to prevent a feeling of stuffiness and increase the coolness. If the air permeability exceeds 100 cc / cm ² / sec, the heat retaining property in the clothes cannot be maintained, and the wind from the outside air passes through the cloth and enters the clothes, so that the body temperature is lowered and the function of the winter clothes. Will not exhibit.

  The woven fabric in the present invention preferably has a cover factor of 800 to 2000, more preferably 900 to 1900, and still more preferably 1000 to 1800. When the cover factor is less than 800, the gap formed by the warp and the weft becomes large, so that there is a complaint that the heat retaining property is lowered or the short fibers of the inner cotton material are blown out. If the cover factor is greater than 2000, the gap formed by the warp and weft will be smaller, resulting in lower ventilation and insufficient ventilation. It is difficult to prevent and improve the coolness.

Humidity transferability is mentioned as a scale for quantifying the moisture absorption / release performance of the cloth for clothing in the present invention. Humidity transferability refers to the ability to release moisture in clothes to the outside, and measures the amount of humidity transfer that passes through the fabric from a high-humidity environment to a low-humidity environment. Humidity migration amount is preferably at least 400g ^{/ m} 2 · HR, more preferably 450~2000g ^{/ m} 2 · HR. If the amount of humidity transfer is less than 400 g / m ² · HR, it will not be possible to absorb moisture released from the body and release it to the outside, especially when worn in a humid environment and feeling of stuffiness and stickiness Increases discomfort. When the amount of humidity transfer exceeds 2000 g / m ² · HR, the amount of moisture transpiration from the body increases, and as a result, the skin's moisturizing action decreases significantly, causing skin to become thick and itchy. Failure occurs. The details of each measurement method will be described later.

  Cellulosic long fibers used in at least one of the upper and lower fabrics include copper ammonia rayon, viscose rayon (including strong rayon, polynosic rayon, and high wet modulus rayon), purified cellulose (lyocell), acetate fiber, and the like. . The yarn fineness is 33 to 133 dtex, preferably 56 to 111 dtex, and the single yarn fineness is not particularly limited, but is 0.5 to 10 d, preferably 0.6 to 6 dtex. Most preferably, this yarn is a non-twisted yarn and used as a raw yarn (flat yarn). However, in order to improve the convergence of the yarn, the long fiber yarn is lightly twisted (about 10 to 200 T / M) or interlaced, or subjected to crimped bulk processing such as false twisting or air injection processing. It may be given. For the purpose of obtaining special surface effects and tactile sensations, it is also possible to use yarns that are strongly twisted on warps.

Polyester long fibers can also be used for the woven fabric in the present invention. The polyester long fibers are homopolymers such as polyethylene terephthalate, polybutylene terephthalate, polytrimethylene terephthalate, polyester copolymers with these polymers, and the like. A fiber made of a polyester polymer having a fiber-forming property is used. There may be no problem even if additives such as antistatic agents, flame retardants, heat-resistant agents, light-proofing agents, and titanium oxide are added to the fibers. The cross-sectional shape of the fiber is not particularly limited, and in addition to the round shape, triangular shape, L shape, Y shape, T
The shape may be a polygonal shape, or a multi-leaf shape, a hollow shape, a flat shape, or an indeterminate shape. The yarn fineness is 33 to 133 dtex, preferably 56 to 111 dtex, and the single yarn fineness is not particularly limited, but is 0.5 to 10 d, preferably 0.6 to 6 dtex. Most preferably, this yarn is a non-twisted yarn and used as a raw yarn (flat yarn). However, in order to improve the convergence of the yarn, the long fiber yarn is lightly twisted (about 10 to 200 T / M) or interlaced, or subjected to crimped bulk processing such as false twisting or air injection processing. It may be given. For the purpose of obtaining special surface effects and tactile sensations, it is also possible to use yarns that are strongly twisted on warps.

  In the woven fabric in the present invention, the warp and / or the weft are preferably cellulosic long fibers. Therefore, even if a polyester long fiber is used for the warp and a cellulose long fiber is used for the weft, a cellulose long fiber is used for the warp and a polyester long fiber is used for the weft, and both the warp and the weft use the cellulosic long fiber warp. However, in any case, it is not particularly limited, but in the case of expensive clothes that require comfort (moisture absorption / release performance, humidity transfer and antistatic properties) and drapeability when actually worn The warp / weft is preferably a 100% cellulosic lining made of a combination of cellulosic long fibers. In addition, the above-mentioned lining fabric may be used on either the front or back side, or on both front and back sides, and it is not particularly limited, but it is preferable to use it on both sides. Comfort is improved.

  Examples of the woven structure include plain weave, twill weave, and satin weave. Which woven structure is used can be appropriately determined depending on the use area of the lining, required characteristics, and the like. For example, with regard to women's clothing, a thin and soft texture is preferred, so that a plain weave lining is particularly preferred. Moreover, as long as the effect of the present invention is not hindered, it may be subjected to processing such as conventional scouring, dyeing, and heat setting, and physical processing such as glazing press, embossing press, compact processing, flexible processing, heat setting, etc. Chemical processing such as processing, bonding processing, laminating processing, coating processing, vapor deposition processing, antifouling processing, water repellent processing, antistatic processing, flameproofing processing, insectproof processing, sanitary processing, foam resin processing, etc. Application processing such as microwave application, ultrasonic application, far-infrared application, ultraviolet application, and low-temperature plasma application may be performed.

As a main method for forming the fiber accumulation layer, there are a dry method, a wet method, a spun bond method, a melt blow method, and the like. When short fibers are used, a dry method or a wet method is preferable. The dry method is a method of forming a fiber accumulation layer by using short fibers in a spinning card or a random weber by airflow. On the other hand, the wet method is a method in which short fibers are dispersed in water and formed into a sheet by a papermaking process. In any method, the fiber accumulation layer is bonded as it is or by cross-laminating. As a method for bonding the fiber accumulation layer, there are a thermal bond method, a chemical bond method (impregnation method and spray method), a needle punch method, a water flow entanglement method, and the like. Is composed of polyester short fibers, regenerated cellulose short fibers and synthetic short fibers whose cross-sectional shape is a W-shaped cross section, so either the thermal bond method or the chemical bond method by the spray method is performed alone Alternatively, it is preferable to combine both methods. When the thermal bond method is adopted, in addition to A, B, and C, four types including heat-adhesive fibers may be mixed and the fusion point generated by heat treatment may be held between the fibers. In particular, when mechanical external force is applied by household washing or industrial washing, it is required to have excellent sag resistance and no splintering, so that A, B, C and heat-bonding fibers (hereinafter referred to as D) It is preferable to blend four types of the above and have a fusion point between the fibers.

As the heat-adhesive fiber used for the inner cotton material of the present invention, the entire fiber may be composed of a heat-adhesive component, or the heat-adhesive component may be present on a part or all of the fiber surface. good.
D is composed of a heat-adhesive component and a component having a softening point or a melting point higher than that of the heat-adhesive component in that the form stability of D can be increased, resulting in high heat resistance, and part or all of the fiber surface It is preferable to use a thermoadhesive conjugate fiber in which a thermoadhesive component is present. In that case, the mixing weight ratio of the heat-adhesive fibers D in the inside cotton material is preferably 1 to 20% by weight, more preferably 5 to 15% by weight, based on the whole fiber components A to D.
If the heat-adhesive fiber D is 1% by weight or more, it is sufficient for bonding the fiber accumulation layer, and if it is within 20% by weight, there is no problem in flexibility.

  The thermal adhesive component is not particularly limited, and may be an amorphous polymer or a crystalline polymer. Examples include polyesters, polyamides, polyolefins, polyurethanes, and thermoplastic elastomers such as polyester elastomers and polyolefin elastomers. Isophthalic acid copolymerized PET is obtained in that the obtained cotton has an appropriate shape stability flexibility. It is preferably an isophthalic acid copolymerized PBT or a thermoplastic elastomer. The cross-sectional shape of the single yarn is not particularly limited, and may be round, W-shaped, triangular, pentagonal, star-shaped, L-shaped, T-shaped, Y-shaped, H-shaped, π-shaped, + -shaped, # -shaped, * Atypical cross-sectional shape such as a mold, an eight-leaf type, and a dog bone type, or a hollow cross-sectional shape thereof may be used.

On the other hand, the chemical bond method by the spray method is a method in which the binder solution is sprayed uniformly on one side or both sides of the front and back sides and dried, and the binder solution is particularly limited if a general acrylic resin is used. It is not something.
The inside cotton of the present invention is preferably in the form of a non-woven fabric obtained by laminating web-like fiber assemblies in which A, B, C and D are mixed and heat-treated. Of course, it may be a non-woven fabric or a form embedded between the sides, and may be conveniently selected according to the intended use.

The single yarn fineness of A, B, C and D used in the middle cotton of the present invention may be conveniently selected according to the intended use, but is preferably 0.6 to 6 dtex, more preferably 1.0 to 5 dtex. . If it is thinner than 0.6 dtex, single yarn breakage will occur, the productivity in the middle cotton production process will be poor, it will be worn repeatedly in terms of consumption performance, or the appearance quality will deteriorate due to the mechanical external force of home washing and industrial washing, Inferior to compression recovery and sag resistance. If it exceeds 6 dtex, the bending flexibility and the compression flexibility are inferior, and a comfortable wearing comfort cannot be obtained.
The fiber lengths of A, B, C and D used in the middle cotton of the present invention may be conveniently selected according to the intended use. However, if the fiber length is too short, the fiber entanglement will be deteriorated and the card passing property will deteriorate. Therefore, the fiber length is preferably 10 mm or more, and more preferably 20 mm or more. In addition, if the length is excessively long, the spreadability may be reduced and the bulkiness may be deteriorated, so that it is preferably 200 mm or less, and more preferably 100 mm or less.

Since the inside cotton of the present invention is formed by blending A, B and C having excellent bending flexibility, there is no bottoming feeling when compressed even if the weight of the fiber used is small, and Excellent compression flexibility. For this reason, the weight of the inner cotton is not limited and can be selected according to the intended use. For example, in order to obtain a high temperature insulation winter clothing worn in an extremely cold environment, the basis weight is preferably high, preferably 1000 g / m ² or more, and more preferably 1500 g / m ² or more. In addition, for example, when used for applications that require fashionability, wearing comfort, or light weight, such as outdoor casual clothing or women's clothing, it is preferable that the fabric has a low weight per unit area of 500 g / m ^2. It is preferable that it is below, More preferably, it is 300 g / m < ² > or less, More preferably, it is 100 g / m < ² > or less. Similarly, the thickness of the inner cotton may be selected as appropriate.
