Description

The invention, together with fixing the sericin of silk extracted from cocoon, a method for manufacturing及beauty pile woven product of the pile woven product by raw silk was woven in pile form by single twisted silk.

  Conventionally, raw silk extracted from silkworms is composed of two fibroin fibers wrapped with sericin. Fibroin fibers consist of 100 ultrafine fibrils, and these fibril fibers are generally weakly reflected by friction and appear whitish. .

  The sericin is removed from the raw silk, i.e., the fibroin fiber itself is called silk thread, and the characteristics of this silk thread are excellent in hygroscopicity, moisture release, etc., and the feel of the skin is natural and the comfort is allowed to follow other fibers. It is well known that it has the disadvantage that it is weak against friction and has a whitish form of irregular reflection.

  Therefore, a technique is known in which a pile fabric is woven using the characteristics of raw silk containing such sericin, and a pile fabric such as a towel fabric having a good touch is known. In this pile weaving, a technique for weaving a towel fabric by fixing a pile base of a pile fabric by fixing sericin via a crosslinking agent has already been disclosed in Patent Document 1, Patent Document 2, and the like.

  The pile fabric made of raw silk can be made into a pile fabric such as a towel having flexibility due to the unique texture of the pile, but it is a weaving technique depending on the characteristics of the pile. On the other hand, there is disclosed a technique for weaving a soft fabric with a spun yarn instead of a pile weave. That is, a woven or knitted fabric is made from a mixed twisted yarn obtained by twisting water-soluble yarn and spun yarn (natural fibers or synthetic fibers such as cotton, hemp, silk, and wool), and the water-soluble yarn in the woven or knitted fabric is dissolved in water. A technique that can create a knitted or knitted fabric excellent in characteristics such as lightness, air permeability, and quick drying by removing them is disclosed (see Patent Document 3). Similarly, as a technology to give a soft feeling to the yarn itself that weaves the fabric, it is lightweight by dissolving the water-soluble yarn in water and removing it in the state of a mixed twisted yarn consisting of water-soluble yarn and spun yarn. A technique for producing spun yarn excellent in characteristics such as air permeability and quick-drying property and producing various knitted and knitted fabrics using the spun yarn is disclosed (see Patent Document 4).

  Usually, the raw yarn used for such a pile weave is pile-woven using a twisted yarn called “moly twist” as a pile warp. Here, the term “twisting” refers to two twisted yarns that are made by aligning two or more raw yarns containing two fibroin fibers extracted from the cocoon, and in the state opposite to the single twisting. This is a technique for twisting the material. This means that even if the twist is not stably heated, the twist will not be untwisted, and it is easy to produce a pile fabric by stable twist, and weaving a pile weave with raw silk usually uses these twisted yarns as pile warp yarns Yes.

  However, when weaving a pile fabric with raw yarns of various twists, the solidification phenomenon due to sericin fixation and complicated twisting technology makes it easy to feel the touch, and there are many raw yarns that make up the twists. Twisting in the opposite direction causes untwisting of the raw yarn, creating gaps between the yarns and excessively diluting the weaving density, hygroscopicity, moisture release, heat retention, wear resistance, elasticity, hand feeling, etc. However, it has a disadvantage that is disadvantageous.

  In this way, the phenomenon that causes the above-mentioned defects occurs because of the use of various twists in the pile fabric, but the reason for using the twists in the first place is that weaving the pile woven fabric by single twisting instead of twisting using conventional raw yarn This is because there was no idea. The reason for this is that, as described above, since the raw yarn of sericin foreskin extracted from the cocoon is twisted to form a woven yarn by twisting usually four pieces, each raw yarn is likely to fall apart during the weaving process. This is because the work is troublesome, and in order to prevent the disadvantages of falling apart, it has to be tightly twisted. Then, the texture disappears and the original feel and texture of silk are reduced.

  Therefore, the above-mentioned drawbacks associated with various twists are eliminated by carrying out the raw yarn by single-twisting instead of multiple-twisting, and furthermore, the above-mentioned disadvantages associated with single-twisting by adding a technique of weaving and dissolving water-soluble yarns during single-twisting The technique of pile weaving raw silk to eliminate the problem is considered. That is, in the present invention, a pile is woven by twisting a single twisted raw yarn and a water-soluble yarn to form a towel fabric or the like.

  That is, in the present invention, when pile weaving using raw yarn, a single-twisted twisted yarn of four to eight raw yarns subjected to sericin fixing treatment with a crosslinking agent is used, but the twist is not tightened when the raw yarn is single-twisted In addition, the water-soluble yarn is dissolved in the twisted yarn using a water-soluble water-soluble yarn, and then the water-soluble yarn is dissolved, the pile does not come off and the stability and the original texture of the silk are improved. An air layer in between is formed sufficiently, and there is a soft feeling, and a pile woven product with raw silk excellent in hygroscopicity, moisture release and the like can be obtained.

  The present invention includes a sericin fixing process performed on raw silk, a single-twist process in which several raw silks are single-twisted by a loose sweet twist, and a water-soluble thread is twisted in the opposite direction to the single-twist. Does not provide a method for producing pile woven products with raw yarn, characterized in that the mixing treatment for producing mixed twisted yarn, the dissolving treatment for dissolving the water-soluble yarn, and the pile weaving treatment performed by the mixed twisted yarn are performed in any order. It is what.

Further, twisted several of Se lysine fixing processing raw yarn slack loose form twisted sweetness by Ridekata twist twisting and twisting the strip twist Ri that, the water-soluble yarn subjected to dissolution treatment in Katayo Ri twisting direction opposite it is to St. provide pile woven product characterized by being made of pile cloth by the mixed Goyo yarn.

  According to this invention, in pile weaving using raw yarn, sericin fixing treatment performed on the raw yarn, single twisting treatment in which several raw yarns are single-twisted twisted yarn by loose sweet twist, and water-soluble yarn in the single twisted yarn The sericin is piled up in a random order by mixing in a random order a mixing process that produces a mixed twisted yarn by twisting in a direction opposite to the single twist, a dissolving process that dissolves the water-soluble yarn, and a pile weaving process that uses the mixed twisted thread. Bundles twisted yarns that tend to settle and break apart, making it possible to retain the shape of the pile weave, and improve moisture absorption while feeling the texture when used as a pile woven fabric be able to.

  Furthermore, by adopting a single-twisted, sweet-twisted state that takes into account the texture, it becomes a dense pile ground when the piles are arranged in an evenly ordered manner, making the pile form stable. It has the effect of improving the hygroscopicity and moisture release characteristics that are unique to silk, and also has good wear resistance, making it a pile-shaped pile shape with a pile pile and improving elasticity. effective.

  In particular, because the twisting method is not a tightened state in the single-stranded raw yarn, but in a relaxed state, the single-twisted yarn by the raw yarn was included in the fixing sericin when weaving into the pile weave (pile-up movement) When the fibroin fiber is entangled with the fibroin fibers of adjacent single twisted yarns, the single twist is a relaxed sweet twist, so that an optimum gap is created between them and the gap is combined with the gap between the piles. This creates a feeling of roughness on the surface of the fabric, and when it is made into a pile fabric, it gives the human skin a sense of roughness on the surface of the fabric, for example, improves the foaming of soap, and drys the sensitive skin like a baby. As a friction cloth, there is an effect capable of giving a pleasant stimulus.

  In addition to the effect of making a single-twisted twisted yarn by such a sweet twist of raw silk, the water-soluble yarn was dissolved by twisting the water-soluble yarn in the raw twisted twisted yarn in the opposite direction to the single twisted yarn. Later, the melted part of the water-soluble yarn becomes voids, and air is included, and when the reverse-twisted water-soluble yarn dissolves, the untwisted unwinding stress acts on the raw yarn that has already become a single-twisted twisted yarn. Thus, the effect of sweet twisting can be further increased, and the fluffy feeling after pile weaving with raw silk can be doubled.

  Also, mixing with sericin fixing treatment performed on raw yarn, one-twisting treatment that turns several raw yarns into one-twisted twisted yarn by loose sweet twist, and twisting water-soluble yarn into one-twisted twisted yarn in the opposite direction to one-twisted Pile weaving manufactured by a method for manufacturing a pile weaving product with raw yarn, characterized in that mixing processing for producing twisted yarn, dissolution processing for dissolving water-soluble yarn, and pile weaving processing performed by mixed twisting yarn are performed in any order. It is intended to provide products.

  An embodiment of the present invention will be described in detail with reference to the drawings.

The pile woven product in the present invention is manufactured according to the following main processing contents (A) to (E), but the processing steps are the order of each processing as in the first to sixth embodiments described later. A plurality of pattern processing steps with different values can be considered.
(A) Sericin fixing treatment to raw yarn (B) Single twist treatment of raw yarn (C) Mixed twist yarn formation treatment by reverse twist of single twist raw yarn and water soluble yarn (D) Dissolution treatment of water soluble yarn (E) Mixing Pile weaving with twisted yarn

  Hereinafter, each processing content mentioned above is demonstrated.

[(A) Sericin fixing treatment to raw silk]
The yarn unwound from the cocoon, that is, raw silk (kito), contains two fibroin fibers (silk) inside and is covered with sericin. Usually, sericin is composed of about 25% by weight and fibroin fiber is composed of about 75% by weight, and the fibroin fiber contains hundreds of ultrafine fibril fibers. In general, such ultrafine fiber fibrils are weak against friction and look whitish due to their diffuse reflection.

  The raw silk of such sericin foreskin is fixed with sericin using a crosslinking agent. This sericin fixing treatment is carried out using a cross-linking agent or the like, using a cheese dyeing machine, a koji dyeing machine, or the like, circulated at 70 to 90 ° C. for 70 minutes, washed with water, and further circulated with a weak acidic solution for 10 minutes. The sericin can be fixed to the raw silk by washing with water and drying after the treatment.

  Examples of the crosslinking agent include dichlorotriazine crosslinking agent, polyhalogenopyrimidine crosslinking agent, difluoromonochloropyrimidine crosslinking agent, fluoromethylchloropyrimidine crosslinking agent, dichloroquinoxaline crosslinking agent and / or glycidyl ether crosslinking agent. Single or mixture can be used.

  In the present invention, in addition to the case where the sericin fixing process is performed in the state of the raw silk unwound from the cocoon, several (for example, 4) In some cases, the sericin fixing treatment is performed in a state in which the raw yarn of this) is twisted with a single twist.

[(B) Single twist processing of raw silk]
In this raw yarn single-twisting process, four raw yarns (kiito) unwound from the cocoon are twisted to form a single-twisted yarn, and in addition, a single-twisted raw yarn having a relaxed sweet twist is produced.

  There are three known methods of twisting raw silk: sweet twist, normal twist, and strong twist. A sweet twist is a twist of about 300 twists or less (300 twisted parts) per 1 m of raw silk, and a normal twist is a twist of about 500 to 600 times per 500 m of raw silk (500 to 600 (Strong part) is a twisting method, and strong twisting refers to a twisting number of about 800 times or more (800 twisted parts) per 1 m of raw yarn.

  The physical properties of the fabric vary depending on the number of twists of the raw yarn. That is, the present invention is characterized in that the raw yarn used in the weaving of the pile weave is a predetermined sweet-twisted raw yarn, thereby creating a texture and function that are completely different from those of a conventional pile fabric.

  In the present invention, several raw silks extracted from the cocoon are bundled, several bundled raw silks are aligned and twisted to form a 60 to 180 denier yarn, and the single twisted raw yarn is used. Denier is a unit representing the thickness of a yarn. One denier is 9,000 m at 1 g, and the yarn becomes thicker and the denier number increases as the weight increases at 9,000 m.

  In the present invention, a raw yarn of 60 to 180 denier or 12 to 20 denier is subjected to a sweet twist of 80 to 200 times per meter by single twist. Accordingly, when a pile fabric having a pile height of about 3 mm is formed by normal pile weaving, for example, when the number of twists is set to 100 times, one strand of raw silk having a length of about 10 mm (one twist) Part) will be formed.

  That is, as shown in FIG. 3 (a), the gap L between the twisted part d and the twisted part d is about 10 mm, and in the pile ground where the pile height is about 3 mm, one piece per pile. The twisted portion d is formed, or the pile base portion has a twisted portion and the pile itself does not have the twisted portion d.

  As shown in FIG. 3 (b), in the case where the number of twists is about 200 single twists, two twists (two twisted portions d) are formed on a raw yarn having a length of 10 mm. In a pile ground having a height of about 3 mm, a maximum of two or one twist portion exists in one pile.

  In addition, since the bundle yarn of the raw yarn extracted from the cocoon is formed between the twisted portions of the pile, the surface of the bundle yarn is easily separated and the raw yarn becomes fluffy. From the above, it is assumed that in a pile ground having a height of about 3 mm, there are only 0 to 2 twisted portions in one pile (Wana). Considering the texture, moisture absorption, heat retaining function, etc., the following conclusions are reached.

  That is, since there are only 0 to 2 twisted portions in the pile, a predetermined gap is formed between the raw yarns constituting the pile, and in this gap, a fine yarn is formed on the raw yarn surface of the bundled yarn of 20 to 60 bundles. The raw silk is in a vegetation-like vegetation state, and the raw silk is scattered between the twisted portions. Therefore, the fine nap of raw silk or loose raw silk is densely packed between the piles, so that the heat retention function and the moisture absorption function by capillary action can be further improved. The loose hairs become dense and the texture is good. Furthermore, since the twisted portions are scattered at regular intervals and several bundled yarns are in a single-twisted state, the piles can be woven in order as much as possible, and the pile ground can be made uniform throughout. Can be texture.

  A single twist raw yarn produced by such a twisting method (that is, a sweet twist with a single twist of about 100 times or about 200 times the number of twists) has a gap between the yarns when the yarn is used as a pile warp. Since they are sequentially formed, adjacent piles are densely formed by a single twisted raw yarn of sweet twist.

[(C) Generation of mixed twisted yarn by reverse twisting of single strand raw yarn and water-soluble yarn]
In this mixed twisted yarn production process, water-soluble yarn is twisted and mixed in the direction opposite to the twisted direction of the single twisted raw yarn using the single twisted raw yarn formed by sweet twisting the raw yarn unwound from the cocoon. Create twisted yarn.

  The water-soluble yarn for twisting together with the untwisted raw yarn is not particularly limited as long as it has solubility in water. In particular, as the water-soluble yarn, the water-soluble yarn itself is used alone at a predetermined temperature ( For example, a water-soluble yarn having a water solubility of a predetermined ratio (for example, 95% or more of mass) when immersed in hot water at 70 ° C. or higher and left for a predetermined time (for example, 30 minutes) is preferable. That is, if the water-soluble yarn has low water solubility, the water-soluble yarn in the mixed twisted yarn will not be sufficiently dissolved, and it will be difficult to obtain a pile warp made of raw yarn that is light, has a large volume, is very soft, and has excellent tactile sensation.

  Any water-soluble yarn may be used as long as it has sufficient water solubility, and water-soluble polyvinyl alcohol fibers, water-soluble ethylene-vinyl alcohol copolymer fibers, water-soluble polyamide fibers, and the like can be used. In particular, water-soluble polyvinyl alcohol fiber and water-soluble ethylene-vinyl alcohol copolymer fiber are preferably used from the viewpoints of fiber strength, high solubility in water (hot water), biodegradability, and availability. Water-soluble polyvinyl alcohol fibers have been widely known, and are sold as, for example, water-soluble vinylon. These water-soluble resins can be used alone or in combination of two or more.

  The water-soluble yarn may be a spun yarn or a filament yarn (long fiber) as long as it is water-soluble. Filament yarn is preferred because it is easy to dissolve and remove with a hydrophilic solvent. Furthermore, when dissolving and removing the water-soluble yarn, the water-soluble yarn can be removed quickly and satisfactorily, it is easy to use a spun yarn with a fine count, and the mixing ratio of the water-soluble yarn in the mixed twisted yarn can be reduced. In particular, multifilament yarn is particularly preferable because the cost can be reduced.

  The thickness of the water-soluble yarn is, for example, from the viewpoint of ease of twisting with the single-stranded raw yarn, ease of dissolving and removing the water-soluble yarn from the single-stranded raw yarn, productivity of the water-soluble yarn, for example, The same thickness of 60 to 180 denier or 12 to 20 denier is desirable. Further, the ratio of the composite raw yarn to the water-soluble yarn is preferably about the former / the latter = 90/10 to 70/30 in weight ratio, for example.

  According to the ratio of the above-mentioned single-stranded raw yarn and water-soluble yarn, the water-soluble yarn is dissolved and removed from the single-stranded raw yarn with water, and then swollen, textured, lightweight, heat retaining, flexible, woven and knitted, An expanded yarn excellent in stability and the like can be formed. Woven knitted fabric (pile woven product) obtained using this expanded yarn is lightweight and volume, very soft and excellent in tactile sensation, excellent in heat retention and water absorption, excellent in sustainability of these performances, and fluffing There is no pilling resistance.

  In mixed twisted yarns, the number of composite raw water and water-soluble yarn (number of yarns) is as follows: the texture of the pile warp by the raw yarn, lightness, swelling, restriction of the number of krills of the twisting machine, quality control, On the other hand, it is preferable that the number of water-soluble yarns is 1-2.

  In the mixed twisted yarn woven by twisting the single twist raw yarn and the water-soluble yarn, the twist direction of the mixed twist yarn (twist direction in twisting two types of the single twist raw yarn and the water-soluble yarn) is: The direction is the opposite of the twisting direction of the twisted raw yarn. Furthermore, the number of twists of the mixed twisted yarn is the same as that of the single twisted raw yarn and is about 100 times or 200 times per 1 m.

  In this way, by making the number of twists of the mixed twisted yarn the same as that of the single twisted raw yarn, the form stability of the mixed twisted yarn (when the upper twist is performed) (when twisting is performed) The upper twist acts in the direction of untwisting the single twisted raw yarn (bottom twist), and the length of the single twist raw yarn becomes longer during the upper twist. Furthermore, a mixed twisted yarn is formed with a water-soluble yarn in a direction opposite to the twisting direction of the single twist raw yarn, but the raw yarn fibers constituting the single twist raw yarn are untwisted while being untwisted. The twist direction is maintained. For this reason, the raw yarn of the single twist raw yarn is rearranged during the upper twist. As a result, the untwisted raw yarn is swollen, and it is possible to form the swollen mixed twisted yarn of the present invention which is excellent in texture, lightness, heat retention, water absorption, and the like, and excellent in the sustainability of these performances.

[(D) Dissolution treatment of water-soluble yarn]

  In the dissolution treatment of water-soluble yarn from the mixed twisted yarn of single-stranded raw yarn and water-soluble yarn, the water-soluble yarn is dissolved and removed in the mixed twisted yarn state, and in the state of the pile fabric woven by the mixed twisted yarn. The water-soluble yarn may be dissolved and removed. In the case of dissolving and removing the water-soluble yarn in the state of mixed twisted yarn, a method of extracting the mixed twisted yarn for casket, a method of extracting the mixed twisted yarn in a cheese-like state around a bobbin for dyeing, and a mixed twisted yarn Although a method of performing extraction processing in a state of being wound around a dyeing beam can be used, a method of performing extraction processing in a state where a mixed twisted yarn is wound in a cheese shape is preferably used because it can be efficiently produced in a small lot.

  As the hydrophilic solvent, alcohols, ketones, ethers, cellosolves, carbitols and the like can be used in addition to water. These hydrophilic solvents may be used alone or in combination of two or more.

  The method for extracting the water-soluble yarn is not particularly limited, but from the viewpoint that the water-soluble yarn can be efficiently removed by a simple method, a method of immersing in a high-temperature (for example, 90 ° C. or higher) hydrophilic solvent is desirable. When water is used as the hydrophilic solvent, the extracted water may be neutral, or may be an alkali or acidic aqueous solution. Moreover, the aqueous solution which added surfactant etc. may be sufficient.

  The extraction treatment temperature can be adjusted according to the type of fiber constituting the water-soluble yarn, the solubility in the solvent, the shape and thickness of the yarn, etc., and from the point of removal efficiency, it is higher than the temperature (dissolution temperature) at which dissolution starts abruptly It is preferable to perform the treatment at a temperature of (in particular, a temperature about 10 to 20 ° C. higher than the melting temperature).

  The ratio of the hydrophilic solvent is 2 times (mass basis) or more with respect to the mixed twisted yarn, and is preferably about 5 to 50 times, for example. If the amount of the hydrophilic solvent is too small, the removal of the water-soluble yarn becomes insufficient. In addition, when extraction removal is inadequate, you may extract and remove a water-soluble thread | yarn again in a hydrophilic solvent bath using the fresh hydrophilic solvent which does not contain a water-soluble thread | yarn.

  The dissolution treatment time can also be appropriately adjusted in consideration of production efficiency, stability, quality and performance of pile warp using raw silk obtained, and the like, depending on the type of water-soluble yarn, the apparatus used, and the treatment temperature.

  The processing equipment for performing the dissolution treatment is not particularly limited, but the water-soluble yarn can be efficiently dissolved and removed by dissolving and removing the water-soluble yarn using a hook of a yarn dyeing machine. In the case of using a hook of a yarn dyeing machine, dyeing of the swollen yarn obtained by dissolving and removing the water-soluble yarn using the same kettle after dissolving and removing the water-soluble yarn may be performed subsequently. Further, after dissolving and removing the water-soluble yarn from the mixed twisted yarn, the mixed yarn itself or the pile fabric woven with the mixed twisted yarn is washed with water in order to remove the components of the water-soluble yarn adhering to the yarn. Is preferred.

[(E) Pile weaving with mixed twisted yarn]
Pile weaving is performed by using the mixed twisted yarn woven by twisting the single-twisted raw yarn and the water-soluble yarn as a pile warp. Thereby, a pile woven product is woven.

  In the present invention, the above-described (A) sericin fixing treatment to raw yarn, (B) raw yarn single twist treatment, (C) mixed twist yarn generation treatment by reverse twisting of single twist raw yarn and water-soluble yarn, (D It is possible not only to sequentially carry out the water-soluble yarn dissolving treatment and the (E) mixed weaving pile weaving treatment, but also to appropriately change the order of each treatment.

As a result, sericin is fixed to the single twisted raw yarn unwound from the cocoon, and a swollen mixed twisted yarn in which the water-soluble yarn is dissolved and removed from the mixed twisted yarn is generated, and a pile warp is formed from the raw yarn.

  Finally, using the swollen mixed twisted yarn generated in Steps S50 to S52 as a pile warp, (E) a pile weaving process using the mixed twisted yarn is performed, and a pile weave product is woven (Step S53).

[Sixth embodiment]
Hereinafter, a sixth embodiment of the present invention will be described with reference to FIG. In this embodiment, the above-described processes (A) to (E) are executed in the order of (B) → (C) → (E) → (A) + (D) to complete the pile woven product. To do.

  In the sixth embodiment, first, the above-described (B) raw yarn single twisting process is performed (step S60). Thereby, the single twist raw silk formed by carrying out the sweet twist (100 times or 200 times) by the single twist of several (for example, four) raw silk is produced | generated.

  Then, the production | generation process of the mixed twisted yarn by the reverse twist of the above-mentioned (C) piece twist raw yarn and a water-soluble yarn is performed (step S61). As a result, a mixed twisted yarn is produced by twisting the single twist raw yarn and the water-soluble yarn in the direction opposite to the twist direction of the single twist raw yarn.

  Subsequently, using the mixed twisted yarn generated in steps S60 and S62 as a pile warp by raw yarn (E), a pile weaving process using the mixed twisted yarn is performed, and a pile woven product is woven (step S62).

  Finally, the above-described (A) sericin fixing process on raw silk and the above-described (D) water-soluble thread dissolution removal process are simultaneously performed (step S63). As a result, sericin is fixed to the raw yarn (composite raw yarn) constituting the mixed twisted yarn, and the pile woven product is piled with pile warp by the raw yarn expanded by dissolving and removing the water-soluble yarn from the mixed twisted yarn (step S63). .

  The fifth and sixth embodiments described above are characterized in that the sericin fixing process on the raw yarn constituting the mixed twisted yarn and the water-soluble yarn dissolving and removing process from the mixed twisted yarn are performed simultaneously. That is, using a cheese dyeing machine, a koji dyeing machine, etc., mixed twisted yarn by washing with water after circulating treatment for a predetermined time (for example, 70 minutes) with high-temperature water (for example, 70 ° C. to 90 ° C.) containing a crosslinking agent. The water-soluble yarn is dissolved and removed from the sericin, and the sericin can be fixed to the raw yarn by washing with water and drying with a weak acidic solution for 10 minutes. As described above, by performing the sericin fixing process and the water-soluble yarn dissolution and removal process at the same time, the process leading to the weaving of the pile woven product in the present invention can be shortened.

  The mixed twisted yarn formed in each of the above-described embodiments, in a pile ground having a height of about 3 mm, there are only 0 to 2 twisted portions of one twist in one pile (Wana), A predetermined gap is formed between the raw silks constituting the pile. In this gap, fine raw silk is in a vegetative state on the raw silk surface of the bundled yarn of 20 to 60 bundles, and the raw silk is between the twisted portions. Is in a state of being scattered.

  In this way, when a water-soluble yarn is dissolved and removed from a specific mixed twisted yarn itself including a raw yarn with a hydrophilic solvent, a swollen composite raw yarn that swells greatly compared to the mixed twisted yarn before removal and has a small torque is obtained. Pile warp can be formed from raw yarns that can improve lightness and pilling resistance, and have improved knitting and productivity.

  Pile warp made of raw silk that has undergone such swelling processing promotes dyeing treatment and lubrication as necessary under conditions that do not reduce swelling, lightness, heat retention, water absorption, texture, etc. For example, a treatment for applying an oil agent, a water repellent treatment, a treatment for applying a functional processing agent such as an antibacterial agent, and yarn processing such as twisting may be performed. In particular, since the dyed yarn is subjected to a water-soluble yarn extraction process in which the color of the dyed yarn is liable to fade, it is suitable for a method of dyeing yarn before weaving a pile fabric.

  The pile warp made of raw silk prepared in each of the embodiments described above is a raw yarn for weaving a pile fabric, and is prepared as a wound yarn wound in a hook or tube shape, and the pile fabric is suitably used for weaving. It is done.
