Description

Technical Field

[0001] The present invention relates to a treatment agent for rayon cones and a rayon cone using the treatment agent for rayon cones. Background Art

[0002] Regenerated cellulose fiber, also known as rayon, has always been commonly used in linings, women's clothing, etc. due to its excellent hygroscopicity, water absorption, gloss and drape.

[0003] When rayon is industrially produced, a method mainly involves the steps of viscose fiber spinning, spinning, drying, and winding.

[0004] In these processes, for example, the yarn strips after the drying process become cylindrical tassels wound with yarn. As a method of forming the tassel, for example, a method of forming a yarn layer on the inner wall of a tank rotating at a high speed by centrifugal force can be adopted.

[0005] In the production of rayon, in order to impart properties such as shape retention of the cone, yarn unwinding (friction with fibers), friction with metals, and antistatic properties to the rayon spun yarn, for example, the rayon spun yarn is treated with an oil agent in the spinning process or in a subsequent process.

[0006] Among them, shape retention is the performance of the fringe tube to maintain the cylindrical state. Once the shape retention is poor, the shape will collapse, and the entanglement between the yarns will make the unwinding property worse, so this situation is not desired in the subsequent processes.

[0007] The unwinding of the yarn is an operation of unwinding the yarn from the cone, and examples thereof include the rewinding process on the cone in the winding process and the rough winding process in the sizing process.

[0008] When unwinding the yarn from the cone tube, if the unwinding property is poor, the fine yarn is prone to breakage. The unwinding property is improved by reducing the friction between the yarns through oil treatment, but the shape retention is reduced. The unwinding property and shape retention are in a trade-off relationship.

[0009] As the above-mentioned oil-based rayon bobbin treatment agent, the technologies described in Patent Documents 1 and 2 have been proposed. Patent Document 1 proposes a mixture of dimethyl alkyl betaine or coconut oil fatty acid monoglyceride and polyoxyethylene castor oil. Patent Document 2 proposes a mixture of a polyoxyethylene ether surfactant, a cationic surfactant of an alkyl polyamine derivative, and an acetate of dimethylol urea.

[0013] Patent document 2: Japanese Patent No. 3966881. Summary of the invention

[0014] Technical issues to be solved

[0015] However, what is expected is a treatment agent for rayon cones with good shape retention and unwinding properties. In the technology described in Patent Document 1, there is a possibility that the shape retention of the cone is insufficient. In the technology described in Patent Document 2, a cationic surfactant is an essential component, but the cationic surfactant is firmly bonded to cellulose and may easily cause insufficient spinning, uneven dyeing and poor sizing.

[0016] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a rayon bobbin treating agent having excellent shape retention and unwinding properties, and a rayon bobbin using the rayon bobbin treating agent.

[0017] Technical solutions to the problem

[0018] In order to solve the above problems, the present invention provides a treatment agent for rayon cones, which comprises (A) an oily component and (B) an anionic surfactant.

[0019] When the total mass of the components (A) and (B) is 100 on a water-free basis, the content ratio (A):(B) thereof is 60 to 99:1 to 40.

[0020] In the present invention, the above-mentioned rayon fringe processing agent is characterized by further comprising (C) a nonionic surfactant in addition to the above-mentioned components (A) and (B).

[0021] When the total amount of the components (A), (B) and (C) is 100 on a water-free basis, the content ratio (A): (B): (C) is 60 to 90: 1 to 20: 1 to 30.

[0022] The rayon cone of the present invention is a rayon cone treated with the above-mentioned rayon cone treating agent.

When the content is within this range, a rayon fringe having excellent shape retention and unwinding properties can be produced. Although the components (B) and (C) as softening components mainly impart unwinding properties, if the content is too large, the shape retention is reduced and the unwinding properties are reduced.

[0071] When the content ratio of the component (A) is 60 or more, the shape retention and the unwinding property are good, and they are even better when the content ratio is 65 or more. When the content ratio of the component (A) is 90 or less, the shape retention and the unwinding property are good, and they tend to be even better when the content ratio is 85 or less.

[0074] It should be noted that the water-free conversion in this specification refers to the effective portion after removing water when the original amount includes water.

[0075] The treatment agent for rayon tassels of the present invention contains at least one selected from the component (B1) and / or at least one selected from the component (C1). When the total mass of the components (A), (B) and (C) is set to 100 in terms of water-free conversion, the total content ratio of the components (B1) and (C1) is preferably 0.5 to 45, and more preferably 8 to 33. When it is within this range, the shape retention and relaxation properties are particularly good. In this case, the treatment agent for rayon tassels of the present invention more preferably contains at least one selected from the component (B1) and at least one selected from the component (C1).

[0076] The rayon cone treatment agent of the present invention may contain other components in addition to the above-mentioned components (A), (B) and (C) within the range not impairing the effects of the present invention. Examples of such other components include water and polyoxyalkylene glycol.

[0077] The rayon cone treating agent of the present invention may be made into an emulsion such as a water-in-oil type in consideration of the operability and the suppression of separation.

[0078] In the rayon cone treatment agent of the present invention, the total weight of the components (A), (B) and (C) is preferably 50% by weight or more, more preferably 90% by weight or more, based on the total weight of the treatment agent on a moisture-free basis.

[0079] The rayon bobbin treating agent of the present invention can be produced by uniformly mixing the respective raw materials according to a conventional method, and can be obtained, for example, by stirring and mixing at a temperature at which the respective raw materials are dissolved.

[0080] The rayon cone of the present invention is a rayon cone treated with the above-described rayon cone treatment agent. Rayon is a regenerated cellulose fiber made of wood pulp as a main raw material, and is produced by wet spinning. For example, cellulose such as pulp and cotton linters is dissolved in an alkali such as sodium hydroxide and carbon disulfide to prepare viscose fibers, and then spun in an acid to produce the rayon fibers.

[0081] When rayon is industrially produced, a method mainly involves the steps of viscose fiber spinning, spinning, drying, and winding.

[0082] Viscose fibers as a spinning stock solution can be spun out from a spinning nozzle into a coagulation bath and fiberized according to a conventional method.

[0083] In the spinning step, for example, the spun yarn is treated with a reagent, washed with water, or treated with an oil agent.

[0084] In the spinning process and the subsequent processes, the yarn is treated with the rayon tassel treatment agent of the present invention as an oil agent. For example, the rayon tassel treatment agent of the present invention is diluted in water to form an immersion bath of 0.2 to 0.5 mass%, and the immersion bath is circulated to immerse the yarn and treat it with a target adhesion amount. The adhesion amount can be 0.1 to 2.0 mass%, preferably 0.1 to 1.0 mass%, more preferably 0.1 to 0.8 mass%, and further preferably 0.1 to 0.4 mass%. Based on the adhesion amount exceeding a certain level, the friction is reduced and the relaxation becomes good. Based on the adhesion amount being lower than a certain level, the possibility of the residual oil agent remaining even in the subsequent process of spinning is reduced, and the probability of affecting dyeing and sizing is small. Method for determining the adhesion amount: Using cyclohexane: ethanol = 1: 1 (volume ratio) as the extraction solvent, extract at 80°C for 4 hours by Soxhlet extraction method, and calculate the adhesion amount by the following formula based on the mass of the yarn after drying and degreasing and the extracted oil.

[0085] Adhesion amount (%) = (extracted oil / line after drying and degreasing) × 100

[0086] The yarn treated with the treatment agent for rayon cone of the present invention is, for example, dried and then made into a cone in which the yarn is rolled into a cylindrical shape. As a method for forming the cone, for example, a method of forming a yarn layer on the inner wall of a tank rotating at a high speed by centrifugal force (centrifugal spinning method) can be cited.

[0087] In the winding process, the yarn is unwound from the fringe tube and rewound onto a cone tube serving as a core, and is supplied to subsequent processes such as braiding and weaving.

[0088] The rayon cone treating agent of the present invention can also be used as a coning oil used when winding into a cone.

[0089] The rayon fringe cone of the present invention may be a coreless fringe cone or may be wound on a core material such as a cone tube.

[0090] The rayon cone treating agent of the present invention can be preferably used as a spinning oil agent for long fibers for the purpose of making the production process smoother, but can also be used as a spinning oil agent for short fibers.

[0091] [Example]

[0092] Hereinafter, the present invention will be described in more detail with reference to Examples, but the present invention is not limited to these Examples.

[0093] 1. Preparation of treatment agent and rayon fringe tube

[0095] Using the above treatment agent, a rayon cone was prepared in the following steps. A rayon cone with a yarn count of 133T / 30f wound on a tank by a centrifugal spinning method was spun using an internal pressure cone spinning machine, treated with a treatment agent diluted with water at 0.35% by mass on a water-free basis, centrifuged and dried using a tunnel dryer to obtain a rayon cone with an attachment amount of 0.2% by mass.
