BEST MODE FOR CARRYING OUT THE INVENTION The flat yarn of the present invention is obtained by aligning a plurality of twisted yarns (hereinafter, twisted yarns are referred to as yarns) in parallel and flat, and mutually using an adhesive. Obtained by bonding.

FIG. 1 shows an embodiment of the production of the flat yarn of the present invention. In FIG. 1, a plurality of yarns 6 are respectively pulled out from a cone 4 and passed through a snail guide 8 to a comb guide 10.
Through in parallel. Aligned yarn 6
Is introduced into the binder tank 20 via the guide roll 12. The binder tank 20 contains an adhesive liquid, that is, a solution or an emulsion liquid 18, and the yarn 6 is impregnated with the adhesive liquid. The yarn 6 that has exited the binder tank 20 is squeezed by the squeezing roll 14, and excess adhesive liquid is squeezed out. Next, the width of the yarn 6 is increased by passing the U-shaped guide 16 so that the individual yarns are arranged side by side and in contact with adjacent yarns. The group of the yarns 6 in this state is introduced into the heater 22, and the adhesive is dried and, if necessary, cured to form the flat yarn 9. The flat yarn 9 is wound as a winding body 26.

FIG. 2 schematically shows the structure of the cross section of the flat yarn 9 thus obtained. In FIG. 2A, the flat yarn 9 is composed of a yarn group 37 in which individual yarns 6 are arranged side by side, and the yarns 6 are adhered to each other by an adhesive 36.
The adhesive 36 covers the surface of the flat yarn 9 when the amount of adhesion is large, but covers a part of the surface of the flat yarn 9 when the amount of adhesion is small.

Further, like the flat yarn 9s shown in FIG. 2 (b), the adhesive 36 mainly intervenes between the adjacent yarns 6,
A structure in which the yarns 6 are bonded to each other by the adhesive 36 may be used.

Further, since the yarn 6 is composed of the single fiber group 32 and twisted, the cross-sectional shape of each yarn 6 is rounded. For this reason, the flat yarns 9 and 9s of the present invention are not completely flat like a mirror surface whose surface is crushed by a hot roll, but have groove-like irregularities due to the thread 6 formed on the surface. With no unevenness, there is no unpleasant glitter,
A calm luster and a unique texture with no unpleasant slime.

The twisting of the yarn 6 may be carried out within the range of the twist coefficient of a normal spun yarn. However, when the yarn is a filament yarn, twisting may be performed with a twist coefficient smaller than the range of the twist coefficient of a normal spun yarn. That is, the number of twists is T
(T / m) and the thickness of the filament yarn is D (dte
x), T is a twist coefficient based on dtex.
The value of × ΔD may be 200 to 10,000. With a twist coefficient smaller than this, the cross section of the yarn is not rounded and groove-like irregularities cannot be formed.

FIG. 3 shows another embodiment of the production of the flat yarn of the present invention. This embodiment is suitable for producing flat yarns composed of spun yarns. In FIG. 3, a plurality of yarns 6a are respectively drawn out from the cone 4a, and are arranged in parallel through a snail guide 8 and a comb-shaped guide 10. The aligned yarns 6a are introduced into the binder tank 20a via the guide rolls 12. The binder tank 20a contains a first adhesive liquid 18a in the form of a solution or an emulsion liquid, and the yarn 6a is impregnated with the first adhesive liquid 18a. The thread 6a that has exited the binder tank 20a is sandwiched between felts 40,
Alternatively, the surface of the felt 40 is rubbed to travel and excess adhesive liquid is squeezed out. Next, the width of the yarn 6a is increased by passing through the U-shaped guide 16, and the individual yarns 6a
Are arranged side by side and in contact with the adjacent yarn 6a. The group of the yarns 6a in this state is supplied to the adhesive applying device 41 for applying the second adhesive. The adhesive application device 41 includes a kiss roll 49 and a processing tank 44. The processing tank 44 is filled with an adhesive liquid 45 of a second adhesive. Thread 6a
Group contacts the kiss roll 49 to pick up the second adhesive and travel. Thread 6a exiting adhesive applying device 41
Is moved between the felt 40 and the surface of the felt 40 by rubbing, and excess adhesive liquid is squeezed out.
Next, the width of the yarn 6a is adjusted through the U-shaped guide 16,
The individual yarns 6a are arranged side by side and in contact with the adjacent yarns 6a, and are introduced into the heater 46. The adhesive is dried and cured as necessary by the heater 46, and the group of the yarns 6a becomes the flat yarn 9a, and the flat yarn 9a is wound as a wound body 26a so that false twist does not enter.

The heater 46 includes a Nelson roll 49 composed of a pair of rolls 48. The group of the yarns 6a runs while being repeatedly wound around the Nelson roll 49.
The yarn 6a stays in the fabric for a long time and is heated.
Group is sufficiently heated.

In the embodiment shown in FIG. 3 of the present invention, when the yarn 6a passes through the binder tank 20a and the felt 40, the fluff of the yarn 6a is lowered and the surface of the yarn 6a becomes smooth, and the yarn 6a becomes smooth. 6a by the adhesive applying device 41
Can be uniformly applied. Also, since the first adhesive filled by the binder tank 20a has penetrated into the inside of the yarn, the liquid of the second adhesive applied by the adhesive applying device 41 is higher than the inside of the yarn 6a. Many are applied to the surface. For this reason, by changing the properties of the first adhesive and the second adhesive, properties such as the feeling of the yarn can be changed. For example, by making the first adhesive flexible and the second adhesive relatively hard, a pliable and smooth flat yarn 9a can be obtained.

The flat yarn of the present invention is provided with excellent properties by a more appropriate selection of the adhesive. That is, by using an acrylic paste mainly composed of an acrylic elastomer as the first adhesive and using konjac paste as the second adhesive, a supple and smooth touch unique to a straw-like natural product can be obtained. . In addition, konjac paste has water resistance, and products such as woven fabric obtained from this flat yarn are:
Withstand washing.

In the present invention, when bonding between yarns is performed with one type of adhesive, a mixed adhesive in which a plurality of types of adhesives are mixed may be used as the adhesive. In an embodiment in which the yarns are bonded with one type of adhesive, a flat yarn manufacturing device 1 having a single-stage adhesive application device 41b as shown in FIG. 5 can also be used. In FIG. 5, a plurality of yarns 6 are pulled out from the cone 4 respectively, and a snail guide 8
Through the comb-shaped guide 10 in parallel.
The aligned yarns 6 are introduced into the binder tank 20 via the guide rolls 12. The binder tank 20 contains an adhesive liquid, that is, a solution or an emulsion liquid 18,
The yarn 6 is impregnated with an adhesive liquid. Binder tank 2
The thread 6 that has exited 0 is sandwiched between the felts 40a and 40b and squeezed, then squeezed by the squeezing roll 14, and excess adhesive liquid is squeezed out. Next, the width of the yarn 6 is increased by passing the U-shaped guide 16 so that the individual yarns are arranged side by side and in contact with adjacent yarns. The group of the yarns 6 in this state is introduced into the drying heater 46b, and the adhesive is dried and, if necessary, cured to form the flat yarn 9b.
b is wound up as a winding body 26b. Drying heater 46
b includes a Nelson roll 49 composed of a pair of rolls 48, a group of yarns 6b runs while being repeatedly wound around the Nelson roll 49, and stays in the drying and heating machine 46b for a long time to be heated. With this, the group of the yarns 6b is sufficiently heated.

Each of the snail guides 8 may be provided with a thread breakage detecting device. Further, the binder tank 20 may be provided with a stirrer for stirring the adhesive liquid. Further, the binder tank 20 may be provided with a heat retaining device or a temperature adjusting means in order to keep the liquid temperature constant.

In the production of the flat yarn of the present invention, when konjac paste is used as an adhesive, the yarn is first impregnated with an aqueous solution of konjac fine powder (seiko) containing mannan as a main component, and then a tank not shown. And then dipped in an alkaline solution such as calcium hydroxide to solidify the konjac, and then dried through a dryer to dry the konjac. Alternatively, the yarn is impregnated with an aqueous solution obtained by mixing an aqueous solution of konjac fine powder (seiko) containing mannan as a main component and an aqueous solution of xanthan, and then the yarn is passed through a heater to solidify the konjac and dry it. Is also good.

In the present invention, an aqueous solution of konjac fine powder (seiko) containing mannan as a main component does not exhibit alkalinity at normal temperature, such as sodium trichloroacetate, but exhibits alkalinity at a temperature of 90 ° C. or more, for example. An agent composed of an organic salt can be mixed. Thus, even if the konjac is not solidified by dipping in an alkaline solution such as calcium hydroxide, an aqueous solution of konjak fine powder (seiko) is attached to the aligned yarn, and then passed through a dryer, for example, at 90 ° C. or higher. Konjac can be solidified only by drying at a temperature. According to this method, the step of solidifying the konjac can be simplified.

When konjac paste is used as the adhesive, the adhesive force between the threads becomes extremely high when cotton yarn is used as the threads. This is presumably because the cellulose constituting the cotton fiber has a high affinity for the molecules of the konjac paste, and the konjac paste penetrates the folds on the surface of the cotton fiber and is firmly bound.

Further, the flat yarn of the present invention can be constituted by plural kinds of yarns. Thereby, composite excellent properties can be imparted. That is, the composite flat yarn of the spun yarn and the filament yarn has a touch of the spun yarn and has a strength close to that of the filament yarn. In this way, each can have excellent points. Also, a flat yarn having a peculiar luster stripe can be obtained by a combination of spun yarns and filament yarns having different lusters. A composite flat yarn composed of yarns having different thicknesses becomes a design yarn having a ridge-shaped stripe. A composite flat yarn composed of yarns of different colors becomes a design yarn having colored stripes. A composite flat yarn composed of a plurality of types of yarns made of different fibers can be made into a flat yarn and then dyed to be a composite flat yarn made of yarns of different colors. Threads of different colors are plied, and the composite flat yarn composed of these yarns becomes a flat yarn having a more complicated color design. Combination of a yarn made of a hygroscopic material and another yarn can provide the flat yarn with hygroscopicity. The flat yarn can be provided with antistatic properties by a combination of the antistatic yarn and other yarns. By combining a yarn having a silky-like texture with another yarn, it is possible to give a flat yarn a silky-like texture. In the flat yarn of the present invention, a flat yarn can be formed by a plurality of yarns having different characteristics, and the flat yarn can maintain the characteristics.

The yarns constituting the flat yarns of the present invention may be bonded to each other by using an emulsion type adhesive, but at least a part of the fibers constituting the yarns is made of a thermoplastic synthetic fiber. The filaments may be heated to weld the thermoplastic synthetic fibers together to bond the yarns together. In addition, a hot-melt type adhesive may be used for adhesion between the yarns. That is, after applying a hot-melt type adhesive to the yarn group, the yarns may be bonded by heating to melt the hot-melt type adhesive. Further, a hot-melt type adhesive melted by heating may be applied to the yarn group to bond the yarns together. The hot melt type adhesive may be applied to the yarn group in a powder form. A fibrous hot-melt type adhesive such as a low-melting fiber is pre-blended or blended or twisted into yarn, and the yarn group is heated to melt the hot-melt type fibrous adhesive. The strips may be bonded together. Such a flat yarn that bonds the yarns by utilizing the melting of the polymer generally has a harder feeling than a flat yarn using an emulsion-type adhesive, but is excellent in washing resistance.

Further, the yarns constituting the flat yarn of the present invention can be bonded to each other by using a mixed solution obtained by mixing an aqueous solution of konjac paste and an emulsion type adhesive.
This makes it possible to adjust the hardness of the flat yarn while maintaining the smooth moisture absorption and the smooth texture.

Further, the bonding of the yarns constituting the flat yarn of the present invention can be carried out by using a mixed solution obtained by mixing an adhesive and a softener such as glycerin. This makes it possible to give the flat yarn flexibility while maintaining the smooth moisture absorption of the flat yarn and the smooth texture.

Further, in the present invention, it is possible to adopt a mode in which the flat yarn adhesive is knitted and woven with the flat yarn to form a fabric, and then at least a part of the adhesive is removed. In this embodiment, corn starch, PV is used as an adhesive.
A. Using an adhesive containing a sizing agent composed of a water-soluble resin such as starch, the knitted fabric is desizing in a desizing and refining step using hot water. For desizing, sodium carbonate, enzymes, oxidizing agents and the like can be used as desizing agents. In the fabric obtained in this mode, a plurality of yarns are arranged in substantially parallel to all the eyes of each structure, and the yarns are desizing in a state where the restraint between the yarns is small. Excellent heat retention. Further, the restraint between the yarns is small, and the texture of the knitted fabric is soft. The texture of the knitted fabric can be adjusted by changing the removal ratio of the resin to be removed.

The flat yarn of the present invention may be used alone, or may be used as a fabric made by mixing with other yarns by means of twisting, twisting, blending, knitting and the like. Good.

(Example 1) As the yarn, a 20 / 1-count cotton yarn was used to produce a flat yarn according to the embodiment shown in FIG. That is, six cotton yarns were pulled out from the cone 4a and passed side by side through the comb-shaped guide 10 in parallel.
The assorted yarns run in parallel, but each one was separated by a horizontal space. The aligned yarn is passed through the guide roll 12 and the binder tank 20.
a. The running speed of the yarn was 70 m / min. The binder tank 20a was filled with an emulsion of an acrylic paste mainly composed of an acrylic elastomer as a first adhesive. The pure content in the emulsion is 30%. The yarn that exited the binder tank 20a traveled between the felts 40, and the excess adhesive liquid was squeezed out. When the excess adhesive liquid is squeezed out, the pickup of the adhesive liquid is 2
00%.

Next, the yarn was introduced into the adhesive applying device 41. The processing tank 44 was charged with an aqueous solution of konjac paste as a second adhesive. The aqueous solution of konjac paste is 2.5 g of konjac fine powder (seiko) whose main component is mannan.
% Aqueous solution and a 1.5% aqueous solution of xanthan in a ratio of 3: 2. This yarn applying device 4
1 through which a liquid of the second adhesive is applied to the yarn and then the yarn is trimmed in width by passing through a U-shaped guide 16 so that the individual yarns are arranged side by side and adjacent yarns Was in contact with Next, the yarn was introduced into the heater 46, and the adhesive was heated and dried, and the yarn was wound into a flat yarn 9a. The amount of konjac paste adhered was 10% by dry weight ratio with respect to the yarn.

The heater 46 includes a pair of Nelson rolls 48.
The yarn was sufficiently heated by running while being repeatedly wound around the pair of Nelson rolls 48 and staying and heating in the heater 46 for a long time. The heating temperature was 97 ° C.

The wound flat yarn 26a was further subjected to a wet heat treatment at 110 ° C. for 10 minutes using a steam setter to complete the adhesion of the konjac paste.

In this embodiment, the yarn is formed in the binder tank 2
By passing through the felt 0a and the felt 40, the fluff of the yarn was turned down, the surface of the yarn became smooth, and the adhesive application device 41 was able to uniformly apply the liquid of the second adhesive to the yarn. . In addition, since the first adhesive permeates the inside of the yarn by passing through the binder tank 20a, the liquid of the second adhesive applied by the adhesive applying device 41 is larger than the inside of the yarn. More applied to the surface. The cross section of the flat yarn 9a obtained in this embodiment is as shown in FIG. 4, and the yarn group 37 is composed of the yarns 6a arranged side by side and arranged in parallel in a state almost in contact with an adjacent yarn. Second adhesive 36a
Covers the yarn group 37 and adheres the yarns 6a to each other. The yarns 34a are also partially adhered to each other by the first adhesive. The yarn 6a is composed of a single fiber 60,
The 0s are bonded to each other by a first adhesive 62.

The first adhesive is flexible, has high water resistance, and has high adhesion to cotton fibers. The second adhesive is relatively hard and has a smooth natural straw touch. In addition, the adhesive force for adhering cotton yarn is extremely high. With such a configuration, a flat yarn that has a flexible and smooth natural straw touch with a deep touch and that can withstand washing is obtained.

The flat yarn was given a twist of 70 T / m, used as a weft, and woven using a 40 / 2S cotton yarn as a warp, and Jinbei was made from the obtained woven fabric. This Jinbei was supple and smooth, and the flat yarn was woven in a three-dimensional spiral form, had good air permeability, and was suitable as clothing in the summer. In addition, the same woven fabric was used as a side of the futon. This futon had a refreshing feeling and was suitable as a summer futon.

Example 2 A flat yarn was manufactured according to the flat yarn manufacturing mode shown in FIG. As the yarn, a yarn of 40th polyester 50 cotton 50 blended yarn is used, and five yarns are respectively drawn out from the cone 4, passed through the snail guide 8, passed through the comb-shaped guide 10, and aligned in parallel.
The aligned yarn is introduced into the binder tank 20 via the guide roll 12. The binder tank 20 contains an adhesive liquid, that is, a solution or an emulsion liquid, and the yarn group is impregnated with the adhesive liquid. The adhesive liquid is pure 3
Consists of 0% rubber latex. The yarn that has exited the binder tank 20 is squeezed by the squeezing roll 14, and excess adhesive liquid is squeezed out. The pick-up of the adhesive liquid is 200%. The yarns are then increased in width by passing them through a U-shaped guide 16 so that the individual yarns are side by side and in contact with adjacent yarns. The yarn in this state is introduced into the heater 22, and the adhesive is dried and cured to form the flat yarn 9, and the flat yarn 9 is wound up as a winding body 26. The heating temperature of the heater is 130 ° C.

The cross-sectional structure of the flat yarn thus obtained is as shown in FIG. 2 (a), wherein the polyester cotton blended yarns are adhered to each other by rubber, and the surface of the flat yarn is Covered by rubber. For this reason, the friction coefficient of the surface of the flat yarn is high, and clothing made of woven fabric made of this yarn has an anti-slip effect when worn, and is used as a yarn for woven fabric of parts that require an anti-slip effect such as an inside belt. The parts that were used and required an anti-slip effect, such as the inside belt, exhibited an excellent anti-slip effect.
Also, since each yarn is spun and twisted,
The cross section of each thread is rounded. For this reason, the flat yarn of the present example is not completely flat like a mirror surface whose surface is crushed by a roll, has groove-like irregularities due to the thread constituting the surface, has no unpleasant glitter, and is calm. It had a gloss.
