Description

  The present invention relates to an on-board oiling agent and its application. More specifically, the present invention relates to an on-machine oiling agent that is applied to a glued yarn on a loom during weaving, an oiling yarn obtained by applying the on-machine oiling agent to a glued yarn, and a woven fabric. It relates to a manufacturing method.

Various performances such as adhesive strength, water resistance, abrasion resistance, tack resistance, and scouring properties are required for the glue used for weaving fibers. Further, when weaving using filament yarn, weaving is performed using a loom in order to improve the production efficiency (for example, Patent Document 1).
Recently, the number of warp deniers has become smaller (fine denier). A yarn having a small number of deniers is thinner and weaker than normal denier, so warp breakage during weaving is likely to occur. Usually, in order to prevent warp breakage at the time of weaving, the amount of glue is increased to increase the convergence of monofilaments. However, when the amount of glue is increased, there is a problem that adhesion that causes poor opening of the warp during weaving occurs or falling glue occurs. From such a point of view, it is desired to develop a glue that can give the yarn an adhesive property that suppresses warp breakage during weaving and an adhesive property that can suppress poor opening, and can suppress the occurrence of falling paste. ing.

  In addition, the warp may be oiled immediately after pasting in order to reduce friction generated between the warp and the metal and the warp (for example, Patent Document 2).

The number of filaments of the multifilament yarn suitable for the paste of the present invention is 3 to 36. The spun yarn (spun yarn) is preferably 20 to 100, more preferably 30 to 90, and particularly preferably 40 to 80.

  Glued yarn obtained by sizing warp glue for fibers into multifilament yarn penetrates into the inside of multifilament yarn, so the space ratio defined by the above formula (1) is higher than that of conventional glued yarn. Get smaller. The effect of the present invention can be further exerted in the case of a glued yarn having a space ratio of not more than a predetermined value below.

  When the number of filaments of the multifilament yarn is 3 to 7, the space ratio is preferably 3% or less, more preferably 1% or less, and further preferably 0.5% or less. When the number of filaments of the multifilament yarn is 8 to 36, the space ratio is 8% or less, preferably 5% or less, more preferably 3% or less. In the case of glued yarn with a space ratio of more than 3% (3 to 7 filaments) or more than 8% (8 to 36 filaments), the paste does not penetrate into the multifilament yarn, and the multifilament yarn There is a tendency to adhere to the surface, which may cause adhesion problems such as poor opening on the weaving machine.

The space ratio defined by the above formula (1) is calculated from the space area N1 inside the glued yarn, the cross-sectional area N2 of the monofilament, and the number of filaments N3 in the glued yarn cross section taken by the electron micrograph. The glued yarn cross section indicates a cross section when cut perpendicular to the extending direction of the multifilament yarn. The inside of the glued yarn refers to the entire inside of the glued yarn having the cross section. The space area is a gap formed between the monofilaments inside the glued yarn, and indicates the total area of the space where the glue component does not exist.
FIG. 2 is a conceptual diagram of the glued yarn showing the space area N1 inside the glued yarn in the section of the glued yarn, the cross-sectional area N2 of the monofilament, and the number of filaments N3 (in this case, seven). The left side of FIG. 2 is a conceptual diagram of a glued yarn cross section with a space rate of 10%, and the right side of FIG. 2 is a conceptual diagram of a glued yarn cross section with a space rate of 0%.

  The sizing method is not particularly limited, and examples thereof include a beam-to-beam method. In the beam-to-beam method, first, a warp beam obtained by drawing a yarn from a creel and a glued box containing a paste are prepared. Next, the yarn was pulled out from the warp beam, passed through the glue box, and the glue was attached to the yarn (glued), and then subjected to non-touch hot air drying and touch cylinder drying. This is a method in which a glued yarn is wound around a glued beam (gluing speed: 50 to 300 m / min, non-touch hot air drying temperature: 80 to 150 ° C., touch cylinder drying temperature: 50 to 130 ° C.).

There is no particular limitation on the adhesion amount of the sizing agent in the glued yarn because it differs depending on the type and thickness of the yarn, but in general, it is preferably 2 to 18% by weight, more preferably 3 to 15% by weight. %, Particularly preferably 4 to 13% by weight. The conditions for measuring the amount of adhesive paste will be described later.
When the yarn is a polyester filament yarn, the adhesion amount of the glue in the glued yarn is preferably 2 to 13% by weight, more preferably 4 to 11% by weight, and particularly preferably 5 to 10% by weight. If the adhesion amount is less than 2% by weight, the adhesion and conjugation tend to be inferior. On the other hand, if the amount of adhesion exceeds 13% by weight, the amount of adhesion is too large, which may cause adhesion problems such as defective opening on the weaving machine.

  The warp paste for fibers preferably contains a neutralized product of a specific copolymer (hereinafter sometimes referred to as paste component A) and wax. When such a warp sizing agent for fibers is used, the sizing agent component can be infiltrated into the inside of the yarn, and the abnormal adhesion portion of the sizing agent on the surface of the yarn can be suppressed. Moreover, plasticization of the paste can also be suppressed. Therefore, it is considered that excellent anti-adhesion property can be imparted to the yarn and the occurrence of falling glue can be suppressed. Further, since the paste penetrates into the inside of the yarn, it is considered that the convergence is improved and the adhesiveness is improved.

Hereinafter, the liquid containing the paste component A and water is referred to as a paste component liquid. The paste component liquid generally has a high viscosity. When measuring the pH of the paste component liquid as it is using a pH meter, the pH concentration after the measurement may be hindered, so the weight concentration of solids contained in the paste component liquid was adjusted to 1%. A value obtained by measuring the pH of the aqueous solution at 20 ° C. is defined as the pH of the paste component liquid. Similarly, the pH of the paste means a value obtained by measuring the pH of an aqueous solution in which the weight concentration of solids contained in the paste is adjusted to 1% at 20 ° C. The method for adjusting the weight concentration to 1% is not particularly limited, but a method of adding distilled water or ion-exchanged water to the paste component liquid or paste, heating and / or drying is performed. And a method of removing volatile components such as water and a hydrophilic solvent.
Here, solid content means the non-volatile component remove | excluding volatile components, such as water and a hydrophilic solvent, from paste component liquid or paste. As shown in the examples, the weight of the solid content is the weight of the component remaining after heating and / or drying the paste component liquid and the paste. In the following description, the weight of the paste component means the weight of the solid content of the reaction mixture obtained after the manufacture of the paste component.

As for the viscosity of the paste component liquid and the paste, the viscosity of an aqueous solution in which the weight concentration of the solids contained in the paste component liquid and the paste was adjusted to 20% was measured at 20 ° C., similarly to the pH described in detail above. Let's mean value. The method for adjusting the weight concentration to 20% is the same as described above.
Similarly to the above, the surface tension of the sizing agent means a value obtained by measuring the surface tension of an aqueous solution in which the weight concentration of the solid content contained in the sizing agent is adjusted to 12% at 20 ° C. The method for adjusting the weight concentration to 12% is the same as described above.

These styrenic monomers may be used alone or in combination of two or more. Among these, styrene, vinyl toluene, α-methyl styrene, p-ethyl styrene, and 2,4-dimethyl styrene are preferable because of high adhesiveness.

  The weight ratio of (meth) acrylic acid in the polymerizable component a is preferably 1 to 30% by weight, more preferably 5 to 25% by weight, and particularly preferably 10 to 20% by weight. If (meth) acrylic acid is less than 1% by weight, abnormal adhesion may occur during pasting. On the other hand, when (meth) acrylic acid is more than 30% by weight, the glue does not penetrate into the inside of the yarn and tends to adhere to the surface of the yarn at the time of gluing. May cause sticking problems.

  The weight ratio of the (meth) acrylic acid ester monomer in the polymerizable component a is preferably 40 to 95% by weight, more preferably 45 to 90% by weight, and particularly preferably 50 to 85% by weight. When the (meth) acrylic acid ester monomer is less than 40% by weight, the adhesiveness tends to be inferior.

  The weight ratio of the styrene monomer in the polymerizable component a is preferably 1 to 30% by weight, more preferably 1.5 to 20% by weight, and particularly preferably 2 to 10% by weight. When the styrene monomer is less than 1% by weight, the adhesiveness of the glue component A to the polyester having an aromatic skeleton is poor, which may cause warp breakage. On the other hand, when the styrene monomer is more than 30% by weight, the adhesiveness and conjugation tend to be inferior.

When the polymerizable component a contains other monomer, the weight ratio is from 100% by weight to the weight ratio of (meth) acrylic acid, (meth) acrylic acid ester monomer and styrene monomer. The remainder after subtracting the sum.

It is preferable to make it as small as possible. Specifically, the weight ratio of the acrylamide monomer in the polymerizable component a is preferably less than 3% by weight, more preferably less than 2% by weight, further preferably less than 1% by weight, particularly preferably 0% by weight. preferable. When the weight ratio of the acrylic amide monomer is 3% by weight or more, the glue does not penetrate into the inside of the yarn and tends to adhere to the surface of the yarn, which may cause adhesion problems such as defective opening on the weaving machine. There is sex.

The copolymerization step is a step of copolymerizing the polymerizable component a by solution polymerization. Thus, if it is a paste which copolymerizes the polymerizable component a by solution polymerization and contains the neutralized product of the copolymer obtained through the neutralization process mentioned later, the warp breakage at the time of weaving is suppressed. Excellent adhesion and tack resistance.
In the copolymerization step, a solvent, a polymerization initiator, a chain transfer agent and the like are used in addition to the polymerizable component a and water, but the polymerization method is not particularly limited as long as it is known. That is, one or two or more methods can be used by methods such as emulsion polymerization, solution polymerization, suspension polymerization, and bulk polymerization. The solution polymerization is preferably performed.

  The solvent used for the polymerization is used for the purpose of improving the compatibility of the polymerizable component a and suppressing the molecular weight of the resulting copolymer. Examples of the solvent include alcohols such as methanol, ethanol, n-propanol, i-propanol, butanol, pentanol, ethylene glycol, and glycerin. Although there is no limitation in particular about the weight ratio of a solvent, Preferably it is 2 to 50 weight% with respect to the polymeric component a, More preferably, it is 6 to 40 weight%, Most preferably, it is 8 to 35 weight%. If the weight ratio of the solvent is less than 2% by weight, the solution stability during copolymerization tends to deteriorate, and further, the molecular weight of the copolymer increases, resulting in the production of a highly viscous product and post-processing. In the scouring in the process, an inferior tendency is seen, which is not preferable. On the other hand, when the weight ratio of the solvent is more than 50% by weight, the molecular weight of the copolymer is lowered, and the adhesiveness and conjugation property of the paste are inferior.

  Although it does not specifically limit as a polymerization initiator, A water-soluble polymerization initiator, an oil-soluble initiator, etc. are preferable. For example, water-soluble polymerization initiators include persulfates such as ammonium persulfate, potassium persulfate, and sodium persulfate; peroxides such as t-butyl hydroperoxide, t-butyl peroxymaleic acid, and succinic peroxide. Azo compounds such as 2,2′-azobis- (2-amidinopropane dihydrochloride); Examples of the oil-soluble initiator include peroxides such as benzoyl peroxide, cumene hydroperoxide, diisopropyl peroxydicarbonate, cumyl peroxyneodecanoate, cumyl peroxyoctoate; azobiscyclohexanecarbonyl, azobis Examples thereof include azo compounds such as isobutylamidine hydrochloride and azobisisobutyronitrile. The weight ratio of the polymerization initiator is not particularly limited, but is preferably 0.1 to 3% by weight, more preferably 0.3 to 2.5% by weight, particularly preferably 0. 0% with respect to the polymerizable component a. 5 to 2% by weight. When the weight ratio of the polymerization initiator is less than 0.1% by weight, it is preferable because the molecular weight of the copolymer is increased, so that a highly viscous product is generated, and in the scouring in the post-processing step, an inferior tendency is seen. Absent. On the other hand, when the weight ratio of the polymerization initiator is more than 3% by weight, the molecular weight of the copolymer is lowered, and the adhesiveness and conjugation property of the paste are inferior.

  Chain transfer agents are sometimes used to suppress the molecular weight of the copolymer. Examples of the chain transfer agent include alkyl mercaptans such as n-dodecyl mercaptan, t-dodecyl mercaptan, n-octyl mercaptan, cyclohexyl mercaptan, lauryl mercaptan; thioglycolic acid such as octyl thioglycolate and 2-ethylhexyl thioglycolate Examples include esters. The weight ratio of the chain transfer agent is preferably 0.8% by weight or less, more preferably 0.6% by weight or less, and particularly preferably 0.5% by weight or less with respect to the polymerizable component a. When the weight ratio of the polymerization initiator is more than 0.8% by weight, the molecular weight of the copolymer is lowered, and the adhesiveness and conjugation property of the paste are inferior.

  Although it does not specifically limit in a copolymerization process, It can carry out with the superposition | polymerization temperature and superposition | polymerization time which were adapted by methods, such as emulsion polymerization, solution polymerization, suspension polymerization, and block polymerization.

  The acid value of the copolymer obtained in the copolymerization step is preferably 90 to 200, more preferably 95 to 180, and still more preferably 100 to 160. A copolymer copolymerized with an acid value within this range can easily penetrate into the interior due to increased wettability between fibers, and can impart excellent adhesion and anti-tacking properties to the yarn. The generation of falling glue can be suppressed. In addition, the acid value as used in the field of this invention means the milligram number of potassium hydroxide required in order to neutralize the carboxyl group derived from (meth) acrylic acid contained in 1 gram of copolymers.

  Next, the neutralization process which neutralizes the copolymer obtained at the copolymerization process is demonstrated. In the neutralization step, an alkaline substance is added to the dispersion containing the copolymer in the presence of water to convert the copolymer into a neutralized product.

  Examples of the alkaline substance include metal hydroxides such as sodium hydroxide, potassium hydroxide, and barium hydroxide; ammonia; trimethylamine, triethylamine, triisopropylamine, tributylamine, triethanolamine, methyldiethanolamine, dimethylethanolamine, and the like. Organic amines etc. are mentioned. These alkaline substances are preferably added dropwise as an aqueous solution dissolved in water. For example, an aqueous solution of an alkaline substance having a concentration of 10 to 30% by weight is prepared and added dropwise to a dispersion containing a copolymer over 10 to 30 minutes. Good. The end point of dropping the alkaline substance can be determined, for example, by changing the dispersion containing the copolymer into a transparent state. In this case, the paste component A is in a state dissolved in water, and the paste component liquid A can be said to be an aqueous solution in which the paste component A is dissolved.

  The neutralization degree of the paste component A is preferably 40 to 100 mol%, more preferably 50 to 90 mol%, and particularly preferably 60 to 80 mol%. If the degree of neutralization of the paste component A is lower than 40 mol%, abnormal adhesion may occur during pasting.

  The pH of the paste component liquid A is preferably 7 to 10, more preferably 7.2 to 9.5, still more preferably 7.5 to 9.2, and particularly preferably 7.8 to 9.0. If the pH of the paste component liquid A is lower than 7, there is a possibility that abnormal adhesion may occur during pasting. On the other hand, when the pH of the glue component liquid A is higher than 10, the glue does not penetrate into the inside of the yarn during gluing, and tends to adhere to the surface of the yarn. May cause problems.

  The viscosity of the paste component liquid A is preferably 60 to 1000 mPa · s, more preferably 80 to 800 mPa · s, and particularly preferably 100 to 600 mPa · s. When the viscosity of the paste component liquid A is lower than 60 mPa · s, the adhesiveness and conjugation tend to be inferior. On the other hand, when the viscosity is larger than 1000 mPa · s, the glue does not penetrate into the inside of the yarn during gluing and tends to adhere to the surface of the yarn, causing adhesion problems such as defective opening on the weaving machine. there is a possibility.

  A copolymer or a neutralized product thereof is an aggregate of homologues having different molecular weights, and the molecular weight is obtained as an average amount. There are several types of definitions of the average molecular weight. For example, number average molecular weight, weight average molecular weight, viscosity average molecular weight and the like are generally used. In the present invention, the weight average molecular weight is used. The weight average molecular weight can be adjusted by a known method such as the ratio of the initiator, the presence or absence of a chain transfer agent, and a solvent. The weight average molecular weight of the copolymer obtained by copolymerizing the polymerizable component a or a neutralized product thereof is preferably 80,000 to 200,000, more preferably 90,000 to 190,000, and particularly preferably 100,000 to 180,000. When the weight average molecular weight is more than 200,000, the glue does not penetrate into the inside of the yarn and tends to adhere to the surface of the yarn when gluing, which may cause adhesion problems such as defective opening on the weaving machine. There is. On the other hand, when the weight average molecular weight is less than 80000, the adhesion and conjugation properties may be inferior.

30-90 degreeC is preferable, as for a glass transition point when a copolymer is measured with a differential scanning calorimeter (DSC), 40-80 degreeC is more preferable, and 50-70 degreeC is further more preferable. If the glass transition point is less than 30 ° C., adhesion problems such as defective opening may occur on the loom. If it exceeds 90 ° C., the adhesiveness tends to be inferior.
In addition, the glass transition point as used in the field of this invention is based on JIS-K7121, and in the part which shows the step-like change of the DSC curve obtained by the DSC measurement mentioned later, from the extended straight line of each base line to the vertical axis direction etc. It is defined as the point (unit: ° C) where the straight line at the distance and the curve of the step-like change part intersect.

  The weight ratio of the paste component A to the solid content contained in the warp paste for fibers is preferably 65 to 98% by weight, more preferably 70 to 98% by weight, still more preferably 75 to 95% by weight, particularly preferably. 80 to 90% by weight. If it is less than 65% by weight of the solid content, the adhesiveness is poor, which may cause warp breakage.

The warp sizing agent for fibers preferably contains a wax. By containing a wax, smoothness is improved, and warp breakage during weaving, poor opening of warp and generation of falling paste can be suppressed.
Examples of the wax include petroleum wax such as paraffin wax and microcrystalline wax; synthetic wax such as polyhydric alcohol fatty acid ester, polyethylene wax and polyethylene oxide; wood wax, carnauba wax, candelilla wax, beeswax, lanolin, rice wax, Animal and plant waxes such as banana wax and sugarcane wax; mineral waxes such as montan wax, ozokerite and ceresin, stearic acid, hardened beef tallow, hardened pork fat and the like. These waxes may be used alone or in combination of two or more.
Among these, from the viewpoint of smoothness, petroleum waxes, synthetic waxes, animal and vegetable waxes, and mineral waxes are preferable, animal and vegetable waxes, petroleum waxes, and synthetic waxes are more preferable, and animal and vegetable waxes and petroleum waxes are particularly preferable. preferable.

Since the wax is oil-soluble, it is usually used as an aqueous dispersion emulsified with a surfactant such as a nonionic surfactant or an anionic surfactant in consideration of dispersibility.
Nonionic surfactants include ethylene oxide adducts of higher alcohols such as lauryl alcohol, cetyl alcohol, oleyl alcohol, stearyl alcohol, and ethylene oxide adducts of phenol alkylated with octyl, nonyl, dodecyl, etc. Is mentioned. Among these, a higher alcohol ethylene oxide adduct of a lauryl alcohol / cetyl alcohol / stearyl alcohol combination system is preferable, and a higher alcohol ethylene oxide adduct of a lauryl alcohol / stearyl alcohol combination system is more preferable.

  Examples of the anionic surfactant include sulfate ester salts and phosphate ester salts of ethylene oxide adducts of higher alcohols such as lauryl alcohol, cetyl alcohol, oleyl alcohol, stearyl alcohol, and benzene sulfonate alkylated with a dodecyl group. Can be mentioned. Among these, a sulfate ester salt of a higher alcohol ethylene oxide adduct of a lauryl alcohol / cetyl alcohol / stearyl alcohol combination system is preferable, and a sulfate ester salt of a higher alcohol ethylene oxide adduct of a lauryl alcohol / stearyl alcohol combination system is further included. preferable.

As a method for preparing the wax, for example, a melted wax and an emulsifier are added to a system in which warm water at 90 ° C. is stirred, and the wax emulsion is diluted with a solid content concentration of 20% while maintaining the emulsification temperature at 90 ° C. Can be obtained.
The weight ratio of the surfactant to the total of the wax and the surfactant is 5 to 45% by weight, more preferably 8 to 40% by weight, and particularly preferably 10 to 35% by weight. When the weight ratio is less than 5% by weight, the emulsification of the wax decreases and it is difficult to obtain a uniform emulsion. On the other hand, if the weight ratio is more than 45% by weight, the film becomes soft and may cause adhesion problems such as poor opening on the weaving machine.

As the step of adding the wax, for example, an aqueous dispersion of wax is prepared separately, and the aqueous dispersion of wax is added to the paste component A obtained in the above neutralization step, and these are mixed and stirred. A process etc. are mentioned.
The weight ratio of the wax to the solid content contained in the paste is not particularly limited, but is preferably 1 to 30% by weight, more preferably 2 to 20% by weight, and particularly preferably 3 to 17% by weight. Is blended into. When the solid content is less than 1% by weight, smoothness tends to be poor. On the other hand, when the solid content is more than 30% by weight, the adhesion and conjugation tend to be hindered due to the wax peeling effect.

  The paste may further contain a paste component other than the paste component A. The paste component other than the paste component A is not particularly limited as long as it is not the paste component A. For example, starch, polyvinyl alcohol, carboxymethyl cellulose, synthetic paste ((meth) acrylic acid polymer, (meta ) Acrylic acid ester polymer, (meth) acrylic acid- (meth) acrylic acid ester polymer, maleic acid polymer and salts thereof, water-soluble polyester, water-soluble urethane, etc.).

When the surface tension is lower than 30 mN / m, the amount of the glue attached during sizing decreases, and the adhesion and conjugation properties may be inferior. On the other hand, when the surface tension is greater than 60 mN / m, the amount of the glue attached during sizing increases, and adhesion problems such as defective opening may occur on the loom.

If a surfactant is used, the surface tension of the paste can be lowered. However, if the surfactant is used more than necessary, the paste may be plasticized to cause an adhesion problem during weaving. By using a neutralized product of a specific copolymer and a wax, an optimum surface tension can be obtained without using a surfactant more than necessary. Therefore, excellent adhesiveness and tack resistance can be imparted to the yarn, and the occurrence of falling glue can be suppressed.
The weight ratio of the surfactant contained in the paste is preferably 0.5 to 4%, more preferably 1.0 to 3.5%, particularly preferably 1.5 to 3.0% of the entire paste. is there. When the weight concentration of the surfactant is less than 0.5%, the adhesiveness tends to be inferior. On the other hand, when the weight concentration of the surfactant is more than 4%, the film becomes soft and may cause adhesion problems such as poor opening on the weaving machine.

  The paste used in the present invention preferably contains water. The weight concentration of the solid content contained in the paste is preferably 5 to 18%, more preferably 6 to 15%, and particularly preferably 7 to 13% of the entire paste. When the weight concentration of the solid content is less than 5%, the amount of the adhesive agent attached during sizing decreases, and there is a tendency that the adhesion and conjugation tend to be poor. On the other hand, if the weight concentration of the solid content exceeds 18%, the glue does not penetrate into the inside of the yarn during gluing and tends to adhere to the surface of the yarn, which causes adhesion problems such as defective opening on the weaving machine. There is a possibility of waking up.

  The pH of the paste is preferably 7 to 10, more preferably 7.2 to 9.5, still more preferably 7.5 to 9.2, and particularly preferably 7.8 to 9.0. If the pH of the sizing agent is lower than 7, abnormal adhesion may occur during sizing. On the other hand, if the pH of the sizing agent is higher than 10, the sizing agent does not penetrate into the inside of the yarn and tends to adhere to the surface of the yarn at the time of gluing. There is a possibility of waking up.

The viscosity of the paste is preferably 10 to 800 mPa · s, more preferably 20 to 600 mPa · s, and particularly preferably 30 to 400 mPa · s. When the viscosity is lower than 10 mPa · s, the adhesiveness and conjugation tend to be inferior. On the other hand, when the viscosity is greater than 800 mPa · s, the glue does not penetrate into the inside of the yarn during gluing and tends to adhere to the surface of the yarn, causing adhesion problems such as defective opening on the weaving machine. there is a possibility.
The warp sizing agent for fibers used in the present invention can be particularly suitably used for thin threads. The preferred thread thickness is the same as described above.

[Textile manufacturing method]
The method for producing a woven fabric of the present invention includes a step of weaving the warp made of the oiling yarn and the weft using a weaving machine. Moreover, the manufacturing method of the textile fabric of the present invention includes a step (1) of applying the on-machine oiling agent on the loom to the glued yarn, and a warp composed of the oiling yarn obtained in the step (1). And a step of weaving the weft yarn using a weaving machine. For the weft, the yarn may be processed, but usually the raw yarn is generally used as it is without any special treatment. Here, step (1) is the same as step (1) in the above-described method for producing oiling yarn.

Examples of the weaving machine include a rapier room and an air jet room dry weaving machine; a water jet room and the like. Among these, it is preferable that the loom is a water jet loom or an air jet loom.
For example, weaving is performed on a weaving machine after passing through the oiling yarns described above one by one through the reeds and reeds. Next, weaving is performed by sandwiching the warp yarn between the warp yarns while moving the warp yarn up and down alternately, for example, and a woven fabric is produced. When the weaving machine is a water jet weaving machine, the fallen glue generated on the weave of the weaving machine is washed away by the jet water used when flying the weft, so that the fallen glue can be effectively suppressed.
