In the production method of the present invention, the surface layer, the intermediate layer, and the back surface layer using the surface layer yarn and the back surface layer yarn, and the intermediate layer yarn having a boiling water shrinkage lower than these yarns. A three-layer structure knitted fabric is obtained.

  Here, the surface layer yarn and the back layer yarn are preferably yarns made of highly heat-shrinkable fibers having a boiling water shrinkage of 15% or more (more preferably 15 to 50%). When the boiling water shrinkage of the surface layer yarn and the back surface layer yarn is large, the intermediate layer yarn can be easily removed from the surface of the surface layer and / or the back layer by applying heat treatment to the three-layer structure knitted fabric. It can be made to protrude and is preferable.

  As such high heat-shrinkable fibers, the following copolyester fibers are preferred. First, the main constituent monomers of the copolyester are terephthalic acid and ethylene glycol, and the third component copolymerized with this main constituent monomer is isophthalic acid, naphthalenedicarboxylic acid, adipic acid, sebacic acid, diethylene glycol, polyethylene glycol, bisphenol. A copolymer polyester resin selected from the group consisting of A and bisphenol sulfone is used. In particular, the copolyester is a copolyester in which the acid component is composed of terephthalic acid and isophthalic acid having a molar ratio (terephthalic acid / isophthalic acid) of 90/5 to 85/15, and the glycol component is composed of ethylene glycol. Is preferred. Next, the copolyester is subjected to a normal spinning process, and the obtained undrawn yarn is drawn by a usual method, whereby a high heat-shrinkable fiber having a boiling water shrinkage of 15% or more can be easily obtained. When obtaining a highly heat-shrinkable fiber having a higher boiling water shrinkage, the obtained undrawn yarn is directly wound at a take-up speed of about 3500 m / min without drawing, and the undrawn yarn is 60-80. It is preferable that the film is slightly stretched at a stretching ratio of 1.3 to 1.5 times at a temperature of ° C.

At that time, the total fineness and the number of filaments of the multifilament are preferably in the ranges of the total fineness of 20 to 300 dtex and the number of filaments of 20 to 300, respectively.

  In the present invention, high heat-shrinkable fibers may be used alone as the surface layer yarn and the back layer yarn. Further, the surface layer yarn and the back surface layer yarn may be different. Furthermore, a plurality of types of fibers may be used as the surface layer yarn and the back surface layer yarn. For example, when a polyester false twisted yarn made of a normal polyester such as polyethylene terephthalate is used as the surface layer yarn and / or the back layer yarn, the surface layer and / or the back layer is preferably heat-shrinkable by heat treatment. That is. In this case, the polyester false twisted yarn may be a normal false twisted yarn having a crimp rate of 18% or more (preferably 20 to 30%). The total fineness and the number of filaments of the false twisted yarn may be the same as those of the high heat shrinkable fiber.

  On the other hand, the yarn for the intermediate layer is preferably a yarn made of fibers having a boiling water shrinkage of 10% or less (more preferably 1 to 10%). When the boiling water shrinkage of the intermediate layer yarn is so small, the intermediate layer yarn can be easily protruded from the surface of the surface layer and / or the back layer by heat-treating the three-layer structure knitted fabric. This is preferable.

  When the intermediate layer yarn is an ultrafine yarn having a single fiber diameter in the range of 10 to 1000 nm, the ultrafine yarn in the finally obtained hair knitted fabric has a surface layer and / or a back layer. Since it protrudes from the surface of this, it is preferable because it gives a slimy feeling similar to natural suede. Such ultrafine yarn having a single fiber diameter in the range of 10 to 1000 nm is obtained by dissolving and removing the sea component of the sea-island type composite fiber composed of the sea component and the island component as described later. be able to.

  In the intermediate layer yarn, the number of filaments is not particularly limited, but is preferably 500 or more (more preferably 2000 to 10,000) in order to obtain an excellent slimy feeling. The total fineness of the intermediate layer yarn (the product of the single fiber fineness and the number of filaments) is preferably in the range of 5 to 150 dtex.

The fiber form of the intermediate layer yarn is not particularly limited, but is preferably a long fiber (multifilament yarn). The cross-sectional shape of the single fiber is not particularly limited, and may be a known cross-sectional shape such as a circle, a triangle, a flat shape, or a hollow shape.
The intermediate layer yarn may be subjected to normal air processing and false twist crimping, but preferably has no crimp.

For example, polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polylactic acid, stereocomplex polylactic acid, polyester obtained by copolymerizing the third component, and the like are preferably exemplified. Such polyester may be material recycled or chemically recycled polyester. Furthermore, the polyester obtained using the catalyst containing the specific phosphorus compound and titanium compound which are described in Unexamined-Japanese-Patent No. 2004-270097 and 2004-21268 may be sufficient.

In the present invention, a three-layer structure knitted fabric is knitted by a conventional method using the surface layer yarn, the back layer yarn and the intermediate layer yarn as described above.
Here, as the three-layer structure knitted fabric, the intermediate layer yarn is easily protruded from the surface of the front surface layer and / or the back surface layer by heat treatment described later, and a warp such as an insertion structure using a three-sheet reed is used. A knitting structure is preferred.

  Moreover, as an intermediate | middle layer thread, it is also preferable to use the sea island type composite fiber formed with a sea component and the island component whose diameter is 10-1000 nm as mentioned above. As such a sea-island type composite fiber, a sea-island type composite fiber multifilament (100 to 1500 islands) disclosed in Japanese Patent Application Laid-Open No. 2007-2364 is preferably used.

  Here, as the sea component polymer, polyester, polyamide, polystyrene, polyethylene and the like having good fiber forming properties are preferable. For example, as an easily soluble polymer in an alkaline aqueous solution, polylactic acid, an ultra-high molecular weight polyalkylene oxide condensation polymer, a polyethylene glycol compound copolymer polyester, a copolymer polyester of polyethylene glycol compound and 5-sodium sulfonic acid isophthalic acid may be used. Is preferred. Among them, a polyethylene terephthalate copolymer polyester having an intrinsic viscosity of 0.4 to 0.6 obtained by copolymerizing 6 to 12 mol% of 5-sodium sulfoisophthalic acid and 3 to 10% by weight of polyethylene glycol having a molecular weight of 4000 to 12000. Is preferred.

  On the other hand, the island component polymer is preferably a polyester such as a fiber-forming polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polylactic acid, or a polyester obtained by copolymerizing a third component. In the polymer, a fine pore forming agent, a cationic dye dyeing agent, an anti-coloring agent, a heat stabilizer, a fluorescent whitening agent, a matting agent, a coloring agent may be added as necessary within the range not impairing the object of the present invention. 1 type (s) or 2 or more types of an agent, a hygroscopic agent, and inorganic fine particles may be contained.

  The sea-island composite fiber composed of the sea component polymer and the island component polymer preferably has a sea component melt viscosity higher than that of the island component polymer during melt spinning. Further, the diameter of the island component needs to be in the range of 10 to 1000 nm. At this time, if the diameter is not a perfect circle, the diameter of the circumscribed circle is obtained. In the sea-island composite fiber, the sea-island composite weight ratio (sea: island) is preferably in the range of 40:60 to 5:95, and particularly preferably in the range of 30:70 to 10:90.

  Such sea-island type composite fibers can be easily produced, for example, by the following method. That is, melt spinning is performed using the sea component polymer and the island component polymer. As the spinneret used for melt spinning, any one such as a hollow pin group for forming an island component or a group having a fine hole group can be used. The discharged sea-island type cross-section composite fiber (multifilament) is solidified by cooling air and is preferably wound after being melt spun at 400 to 6000 m / min. The obtained undrawn yarn is made into a composite fiber having desired strength, elongation, and heat shrinkage properties through a separate drawing process, or is taken up by a roller at a constant speed without being wound once, and subsequently drawn. Any of the methods of winding after passing through may be used. Further, false twist crimping may be performed.

  Next, when the sea-island type composite fiber is contained in the knitted three-layer structure knitted fabric, the three-layer structure knitted fabric is subjected to an alkaline aqueous solution treatment, and the sea component of the sea-island type composite fiber is dissolved and removed with an alkaline aqueous solution. Thus, the sea-island type composite fiber filament yarn is made into an ultrafine fiber having a single fiber diameter of 10 to 1000 nm. At that time, the alkaline aqueous solution treatment may be performed at a temperature of 55 to 65 ° C. using a 3 to 4% NaOH aqueous solution.

  Next, the surface layer and / or the back layer is collected by performing a heat treatment on the three-layer structure knitted fabric, and the intermediate layer yarn is protruded from the surface of the surface layer and / or the back layer, thereby providing hair. A knitted fabric is obtained. The height L of the protrusion is preferably 0.1 mm or more (preferably 0.1 to 20 mm).

  In this case, the heat treatment is preferably a heat treatment by dyeing. The yarn for intermediate layer can be easily protruded from the surface of the front surface layer and / or the back surface layer due to the fringing effect during the dyeing process. The temperature and time for the dyeing process are preferably 100 to 140 ° C. (more preferably 120 to 140 ° C.) and 30 to 60 minutes for sufficiently shrinking the surface layer and the back layer. Further, the temperature of the dry heat preset after the dyeing process and the dry heat final set is preferably in the range of 140 to 180 ° C.

  In addition, before and / or after dyeing processing, conventional alkali weight reduction processing, water absorption processing, water repellency processing, and further UV shielding or antistatic agent, antibacterial agent, deodorant, insect repellent, phosphorescent agent, retroreflection Various processings that impart functions such as an agent and a negative ion generator may be additionally applied as long as the main purpose of the present invention is not impaired. However, it is preferable not to perform raising processing (such as emery processing) and buffing. Even if these processes are not performed, the above-mentioned hairy fabric exhibits a slimy feeling, and therefore, the process is wasted. If these processes are performed, clogging of paper may occur and the processability may be reduced. is there.

  Since the hair knitted fabric thus obtained is a hair knitted fabric obtained without using brushing or buffing, the process is simplified because it has not undergone brushing or buffing. It also has a slimy feeling similar to natural suede. In particular, in the case where the single fiber diameter of the yarn for the intermediate layer is an ultrafine fiber in the range of 10 to 1000 nm, since the ultrafine fiber protrudes from the surface of the front surface layer and / or the back surface layer, particularly excellent slimming Give a feeling.

  In such a hair knitted fabric, in order to obtain a slimy feeling similar to that of natural suede, the protruding height of the intermediate layer yarn is preferably 0.1 mm or more (preferably 0.1 to 20 mm). The density is preferably in the range of 50 to 120 courses / 2.54 cm and 25 to 60 wales / 2.54 cm.

  Further, the textile product of the present invention comprises the above-described hair knitted fabric, outer clothing, sports clothing, inner clothing, shoe materials, diapers, nursing sheets and other medical / hygiene products, bedding, chairs Or a textile product selected from the group consisting of a skin material such as a sofa, a carpet, a car seat, and interior goods. Since such a fiber product uses the above-mentioned hair knitted fabric, it exhibits a slimy feeling similar to natural suede.
