Description

  The present invention relates to a textile product, and more particularly to a sewn textile product having water repellency.

  Fiber fabrics having water repellency are used in various textile products such as kappa, coats, windbreakers, ski wear, down jackets, swimwear, umbrellas, bags, shoes, and hats.

  In order to impart water repellency to the fiber fabric, for example, a water repellent such as a fluorine water repellent, a silicone water repellent, or a hydrocarbon water repellent is used. Among water repellents, in particular, fluorine-based water repellents not only have excellent water repellency and oil repellency, but also have water repellency and oil repellency durability against washing and the like. Widely used in

  In recent years, a fluorine-based water repellent (C8 fluorine-based water repellent) containing a perfluoroalkyl group having 8 or more carbon atoms, which is generally used, is a perfluorooctanoic acid that may affect the environment. Therefore, fluorine-based water repellents (C6 fluorine-based water repellents, C4 fluorine-based water repellents) containing a perfluoroalkyl group having 6 or less carbon atoms have begun to be used.

  In addition, with increasing interest in the environment, there is an increasing demand for water repellents that do not use fluorine-based water repellents using fluorine.

  As water repellents that do not use fluorine-based water repellents (non-fluorine-based water repellents), water-based water repellents using silicone resins and hydrocarbon-based water repellents using paraffin are known (patents) Literature 1, 2, 3).

  In addition, textile products such as kappa, gloves, hats, and coats that are made of a fiber fabric having water repellency are sewn using sewing threads. As the sewing thread, one having a silicon-based smoothing agent or a paraffin-based smoothing agent attached thereto is used in order to increase the sewing speed. It is also known to use a sewing thread having water repellency when sewing a fiber fabric having water repellency (Patent Document 4).

Japanese Patent Laying-Open No. 2015-221952 JP-A-2015-206142 JP2015-120894A Japanese Patent Laid-Open No. 56-112525

  However, after measuring the water repellency, it was found that the water repellency may decrease after a while. Specifically, it has been found that the water repellency decreases with the passage of time after the fiber product obtained by sewing the fiber fabric with the hydrocarbon-based non-fluorinated water repellent adhered thereto is brought into contact with water. .

  As a result of intensive studies by the inventors of the present invention on this cause, it has been found that water gradually permeates around a portion sewn with a sewing thread.

  In addition, after several hours to several days have passed after sewing a fiber fabric to which a hydrocarbon-based non-fluorinated water repellent is adhered with a sewing thread, it follows the line of the yarn constituting the fiber cloth from the location sewn with the sewing thread. In addition, it was also found that the darkening phenomenon of the fiber fabric appears and the appearance quality is lowered. Such a phenomenon is particularly noticeable in down-filled textiles that have many sewing locations and are quilted.

  The present invention solves the above-mentioned problems, and is a textile product obtained by sewing a textile fabric to which a hydrocarbon-based non-fluorinated water repellent is adhered. It is an object of the present invention to provide a fiber product in which a decrease in water repellency performance due to the progress is suppressed and a darkening phenomenon along the line of the fiber fabric is less likely to occur.

  As a result of intensive studies in order to solve the above problems, the present inventors have come up with the present invention.

  (1) The fiber product according to the present invention is obtained by sewing a fiber fabric in which a water-repellent resin containing a hydrocarbon compound is adhered to the surface of a fiber with a sewing thread to which a silicon-based smoothing agent is not adhered. .

  (2) Further, in the textile product according to the present invention, it is preferable that a water-repellent resin containing a hydrocarbon-based compound adheres to the sewing thread.

  (3) Furthermore, in the textile product according to the present invention, the textile product may be one selected from the group consisting of clothes, shoes, bags, tents and sleeping bags.

  According to the present invention, a fiber product obtained by sewing a fiber fabric not containing a fluorine-based water repellent and having a water-repellent resin containing a hydrocarbon-based compound attached thereto, A decrease in water repellency due to the progress is suppressed, and the occurrence of a darkening phenomenon along the stitches is suppressed. Thereby, the textiles excellent in water repellency and design property can be obtained.

<Sewing thread>
The fiber product in the present embodiment is obtained by sewing a fiber fabric with a sewing thread.

  Useful fiber materials constituting the sewing thread include polyester, nylon, acrylic, polyurethane, rayon such as acetate and viscose, and in addition, polylactic acid, aromatic polyamide, polyimide or Chemical fibers such as polyphenylene sulfide, natural fibers such as cotton, hemp, silk or wool, or mixed fibers or blends of these materials can be used, and are not particularly limited. Among these, as a raw material of the fibers constituting the sewing thread, those containing polyester or nylon are preferable.

  Further, the fibers constituting the sewing thread may be either long fibers or short fibers. Further, the yarn using the fiber may be either a multifilament or a monofilament.

  Further, the yarn using the fiber may be any of raw yarn, twisted yarn and processed yarn. The processed yarn is not particularly limited, and false twisted yarn (Woolen yarn, DTY, improved false twisted yarn, etc.), indented yarn, shaping yarn, fretting yarn, taslan yarn, yarn length Subtracting processed yarns, composite processed yarns, fluff processed yarns, entangled focused yarns, entangled mixed yarns, and the like can be used.

  In the present embodiment, a smoothing agent is preferably attached to the sewing thread for sewing the fiber fabric. Examples of the smoothing agent attached to the sewing thread include a fatty acid-based smoothing agent and a wax-based smoothing agent. As the fatty acid-based smoothing agent, fatty acid polyamines, polyamide derivatives, mineral oils and the like can be used. Examples of the wax-based smoothing agent that can be used include animal and plant waxes, mineral waxes, Fischer-Tropsch waxes, polyethylene waxes, and petroleum waxes.

  The amount of the smoothing agent adhering to the sewing thread is 0.05% by mass or more and 3.0% by mass or less, preferably 0.5% by mass or more and 1.5% by mass or less with respect to the sewing thread. If the amount of the smoothing agent adhering to the sewing thread is less than 0.05% by mass, the frictional resistance between the sewing thread, the guide (thread guide) and the needle may increase, and the frequency of thread breakage may increase. . On the other hand, if the adhesion amount of the smoothing agent adhering to the thin yarn exceeds 3.0% by mass, the water repellency may be impaired due to the influence of the smoothing agent.

  However, as described above, in the present embodiment, the silicon-based smoothing agent is not attached to the sewing thread for sewing the fiber fabric. When the silicon-based smoothing agent is attached to the sewing thread, if water adheres to the fiber fabric in which the water-repellent resin containing the hydrocarbon-based compound is attached to the fiber surface, the time from contact with the water If it passes, there exists a possibility that water may soak into a textile fabric. That is, the water repellency may be reduced. In addition, when a fiber fabric having a water-repellent resin containing a hydrocarbon compound attached to the surface of the fiber is sewn with a sewing thread to which a silicon-based smoothing agent is attached, the fiber becomes darker along the yarn line of the fiber fabric. There is a risk.

  Examples of the silicone leveling agent not attached to the sewing thread include dimethylpolysiloxane, highly polymerized silicon, modified amino silicone, modified crosslinkable epoxy silicone, silicone emulsion, silicone oil, or crosslinked silicone resin. It is done.

  In the present embodiment, the silicon-based smoothing agent is not attached to the sewing thread, but the water-repellent resin containing the hydrocarbon-based compound is preferably attached.

  In addition, it is good to use the sewing oil used for the sewing machine used when sewing a textile fabric with a sewing thread without the silicone type smoothing agent. If the sewing machine oil contains a silicon-based smoothing agent, the sewing machine oil adheres to the sewing needle, etc., so that the silicon-based oil adheres to the textile product to be sewn, and the silicon-based smoothing agent adheres to the sewing thread. As in the case, there is a possibility that the water-repellent performance may deteriorate over time or the fibers may become darker.

  Hereinafter, examples of the textile product according to the present embodiment will be described, but the present invention is not limited to these examples. In addition, the measurement and evaluation in each evaluation item of A and B in the following examples and comparative examples were performed by the following methods. In the examples, “%” is “mass%”.

[A: water repellency]
JIS L1092: 2009 Waterproof test method for textile products A test was conducted according to a water repellency test (spray test) to confirm water repellency (water repellency). To check water repellency, immediately after spraying water, remove the holding frame from the table, drop extra water droplets as specified, and immediately determine that about 30 seconds have passed after dropping extra water droplets. The determination was made twice, and the determination was made twice.

  In addition, the test piece was cut into a specified size from the fiber product, and the sewing thread used in each example was used in the vertical direction and the horizontal direction at intervals of 3 cm. We used what to do. A “computer sewing machine CPS5231” manufactured by Brother Industries, Ltd. was used as the sewing machine used for sewing the fiber fabric with the sewing thread.

[B: Observation]
After the fiber fabric was sewn with sewing thread, it was left at room temperature for 7 days, and the surface of the fiber product was visually observed.

Example 1
As a fiber fabric, a nylon fabric (a plain fabric. Warp and weft are both 22 decitex 20 filaments. Raw yarn. Round cross section) was dyed amber with an acid dye, fixed with synthetic tannin, and heat set. I prepared something.

  The following treatment liquid is applied to this fiber cloth (nylon fiber) by the dip-nip method, dried at 130 ° C. for 60 seconds, and then heat-treated at 160 ° C. for 60 seconds to obtain all the fibers constituting the fiber cloth. A fiber fabric having a water-repellent resin containing a hydrocarbon compound on the surface was obtained.

[Treatment liquid containing water repellent resin containing hydrocarbon compound]
Neoseed NR-158 (water repellent. Hydrocarbon compound, manufactured by Nikka Chemical Co., Ltd., solid content 30%) 5%
Becamine M-3 (melamine-based crosslinking agent, manufactured by DIC Corporation, solid content 80%) 0.3%
Catalyst ACX (catalyst, manufactured by DIC Corporation) 0.05%
Water balance

  Next, the obtained fiber fabric is sewn using a sewing thread (made of polyester, spun yarn (non-silicone), # 30, 5000 m, produced, manufactured by Otani Co., Ltd.) to which no silicon-based smoothing agent is attached. , Got a poncho.

  The water-repellent performance of the obtained fiber product was grade 4 immediately after the test. Further, in the determination after 30 seconds, the sewing thread was slightly wet, but had almost the fourth grade water repellency.

  Moreover, when the obtained poncho was observed one week later, no particular change in appearance was observed.

(Comparative Example 1)
Example 1 except that the sewing thread was changed to one with a silicone-based smoothing agent attached (Kingspan (trade name), # 30, made of polyester, spanned thread, 600 dtex, manufactured by Fujix Corporation, white)) The poncho was obtained in the same manner.

  The water-repellent performance of the obtained poncho was grade 4 immediately after the test. However, in the determination after 30 seconds, the wetness spreads at an interval of about 1 cm from the location where the sewing thread is present, the water repellency is about the second grade, and the water repellency is deteriorated.

  Further, when the obtained poncho was observed after one week, it was darkened at equal intervals along the yarn line of the fiber fabric from the sewing thread portion.

  As described above, in the textile product of the comparative example, the water repellency decreased or the darkening phenomenon occurred because the silicon-based smoothing agent adhered to the sewing thread was adhered to the hydrocarbon compound. This is presumed to be due to bleeding on the fiber surface.

(Reference example)
Other than changing the water repellent adhering to the surface of the fiber constituting the fiber fabric from a water repellent resin containing a hydrocarbon compound (Neo Seed NR-158) to a C6 fluorine water repellent (Asahi Guard AG-E081) Produced a textile product in the same manner as in Comparative Example 1. The water repellency immediately after the test of the obtained fiber product was grade 5, and the water repellency was grade 5 even after 30 seconds.

  Moreover, when the obtained poncho was observed one week later, no particular change in appearance was observed.

  As described above, when a fiber product is produced by sewing a fiber fabric using a sewing thread to which a silicon-based smoothing agent that is generally used is adhered, a fiber fabric having a fluorine-based water repellent adhered to the surface of the fiber. However, there was no problem with the fiber products using the fiber fabric, but the fiber products using the fiber fabric with the water-repellent resin containing the hydrocarbon-based compound adhered to the surface of the fiber repelled over time after coming into contact with water. It has been found that a new problem arises that the water quality is lowered and the appearance quality is lowered due to the darkening phenomenon.

  In response to this new problem, in the textile product according to the present embodiment, the fiber fabric in which the water-repellent resin containing the hydrocarbon compound is adhered to the surface of the fiber is replaced with the sewing machine in which the silicon-based smoothing agent is not adhered. Sewing with thread.

  As a result, although it is a fiber product obtained by sewing a fiber fabric that does not contain a fluorine-based water repellent and has a water-repellent resin that includes a hydrocarbon-based compound attached thereto, the water-repellent property with the passage of time after contact with water Can be suppressed, and the occurrence of the darkening phenomenon can be suppressed to prevent the appearance from being deteriorated. As a result, a fiber product excellent in water repellency and design can be obtained.

  As mentioned above, although the textiles based on this invention were demonstrated based on embodiment and an Example, this invention is not limited to the said embodiment and Example. For example, the form obtained by making various modifications conceived by those skilled in the art with respect to the above-described embodiments and examples, and arbitrarily combining the components and functions in the embodiments and examples without departing from the gist of the present invention A form realized by this is also included in the present disclosure.
