Description

  The present invention can be easily processed for synthetic fiber (particularly linear aliphatic polyamide having an amide group, such as a registered trade name; nylon) product such as a stocking for women. The present invention relates to a synthetic fiber reinforcing agent that can be prevented or worn comfortably, and a synthetic fiber reinforcing method.

Various synthetic fiber products have been manufactured, and it is widely known that stockings such as women's pantyhose have improved significantly in recent years. However, the improved strength of these stockings is the tensile strength in the length direction. For example, the strength improvement related to the wire that cuts the fiber by being scratched by protrusions, the fact that it is broken, etc. Still not improved.
In order to improve the strength of synthetic fibers in this way, it is known to perform various treatments at the stage of braiding short fibers and long fibers, but this improves the strength of semi-finished products and products that have already been braided. Such a process was hardly performed.

  Therefore, the present invention provides a synthetic fiber reinforcing agent that can be easily processed on a synthetic fiber product, reinforces the fiber itself that constitutes the synthetic fiber product, and can prevent transmission lines such as stockings. The purpose is to propose.

  The present invention has been proposed in order to achieve the above, and the invention according to claim 1 is characterized by comprising a sucrose fatty acid ester, sodium malate, and sodium bicarbonate as main components, and a reinforcing agent for synthetic fibers. It is about.

  The invention described in claim 2 contains 5 to 20% by weight of sucrose fatty acid ester, 0.2 to 1% by weight of sodium malate, and 3 to 5% by weight of sodium bicarbonate. The synthetic fiber reinforcing agent described in 1. above.

  Further, the invention according to claim 3 is a synthetic fiber characterized in that the synthetic fiber reinforcing agent according to claim 1 or 2 is diluted with water, the synthetic fiber product is immersed therein, and then dried. It relates to a reinforcing method.

The reinforcing agent for synthetic fibers of the present invention can reinforce the synthetic fibers themselves and prevent the occurrence of transmission lines and breaks in, for example, stockings that are products.
In addition, since the reinforcing agent for synthetic fibers of the present invention does not contain expensive chemicals or highly dangerous chemicals, the raw material cost is low, and it is not necessary to use rubber gloves when processing synthetic fibers. The storage container is not particularly limited.
Furthermore, the reinforcing agent for synthetic fibers of the present invention, in addition to the above-mentioned reinforcing effect, has an effect of improving the feeling of wearing the product by shrinking the synthetic fiber itself, an effect of preventing static electricity especially in winter, and washing the synthetic fiber. The effects can be expected.

  Moreover, in order to reinforce a synthetic fiber product using the synthetic fiber reinforcing agent of the present invention, it can be treated by a very simple operation such as immersing the synthetic fiber product in a reinforcing agent aqueous solution diluted with water, Since it can be carried out safely without requiring any special tools, equipment and technical operations, it has extremely high practical value.

  The synthetic fiber to which the reinforcing agent for synthetic fiber of the present invention is applied is a fiber typified by polyamide fiber, polyester fiber, etc., and its product may be stockings for women, underwear, and other products. It is possible to process the dough that is the raw material of the product.

The sucrose fatty acid ester contained in the synthetic fiber reinforcing agent of the present invention has an excellent property of high foaming power with HLB of 7 or more, and is industrially used as a food additive and a food emulsifier. It has been. More specifically, the fatty acid may be a saturated fatty acid or an unsaturated fatty acid, and the esterification degree of the fatty acid is preferably a monoester mainly containing a diester and a triester. For example, sucrose monooleate, sucrose monolaurate, sucrose monostearate, sucrose monomyristate, sucrose monopalmitate, sucrose monolinoleate, etc. can be used.
The content of this sucrose fatty acid ester is preferably 5 to 20% by weight, and if it is 5% by weight or less and 20% by weight or more, the desired high reinforcing effect cannot be obtained.

Sodium malate contained in the synthetic fiber reinforcing agent of the present invention belongs to the hydroxycarboxylate, and is industrially used as a food additive in the same manner as the sucrose fatty acid ester.
The content of this sodium malate is preferably 0.2 to 1% by weight, and the highest reinforcing effect was obtained in this range.

The baking soda contained in the reinforcing agent for synthetic fibers of the present invention is a product containing sodium bicarbonate or sodium bicarbonate as a main component, and industrially, food additives (baking powder, etc.) in the same manner as the above components. It is used as.
The sodium bicarbonate content was preferably 3 to 5% by weight, and the highest reinforcing effect was obtained in this range.

  Thus, the three components of sucrose fatty acid ester, sodium malate, and sodium bicarbonate, which are the main components of the synthetic fiber reinforcing agent of the present invention, are chemicals that are industrially used for food addition. Since the safety is extremely high and each component is an inexpensive material, the raw material cost can be kept low.

Moreover, in the reinforcing agent for synthetic fibers of the present invention, various additives may be blended within a range that does not impair the reinforcing effect. For example, a perfume may be added to diffuse an appropriate aroma during use. .
Although this fragrance | flavor does not specifically limit the kind, safety | security is not impaired by using the thing approved for food addition like the said each component.

  In the reinforcing agent for synthetic fibers of the present invention, water is used together with the above-mentioned components. At the time of use, water is further added appropriately and diluted.

In order to reinforce a synthetic fiber product using the synthetic fiber reinforcing agent of the present invention, the synthetic fiber reinforcing agent having the above composition is appropriately diluted with water, immersed in the synthetic fiber product, and then dried. Good. Note that the reinforcing agent composition used in the above processing method is subjected to concentration management as appropriate, and continuously or repeatedly circulated while adjusting the components appropriately so that the proportion of the constituent components is within the above-mentioned preferred composition range. You may make it use.
In the said process, the dilution density | concentration of the reinforcing agent for synthetic fibers is not specifically limited, For example, it can dilute and use about 10-100 times with water. Also, the immersion time of the synthetic fiber is not particularly limited and depends on the concentration of the aqueous reinforcing agent solution, but may be immersed for about 3 to 30 minutes, for example. Further, the drying is not particularly limited, and depending on the heat resistance of the fiber itself, it may be dried by a known method such as room temperature drying, reduced pressure drying or hot air drying. The synthetic fiber product may be washed prior to the reinforcing treatment, or may be treated without being washed because the synthetic fiber reinforcing agent itself has a washing effect.

The synthetic fiber product treated with the synthetic fiber reinforcing agent having the above composition is activated by the synthetic fiber itself, and the base material itself is reinforced by the unique effect and synergistic effect of each component constituting the synthetic fiber reinforcing agent. The Therefore, for example, in products such as stockings, it is possible to prevent the occurrence of transmission lines and breaks.
Moreover, since the synthetic fiber reinforcing agent of the present invention also acts to shrink the synthetic fiber in a slight amount, it can provide a feeling of comfort (wearing feeling) like a new article in, for example, stretched stockings. Furthermore, since the antistatic effect is also exerted, the feeling of wearing is extremely excellent especially for a woman with sensitive skin in a dry season such as winter.
These changes, that is, the treatment effect, are considered to be due to the collapse of some of the micron-sized fine bubbles generated in the synthetic fiber and the contraction of the fiber.

  Furthermore, since each component constituting the synthetic fiber reinforcing agent of the present invention is a chemical that is industrially used as a food additive or food as described above, it is extremely safe, and the synthetic fiber. There is no need to use a storage container to which a special material or treatment is added even if it is touched with bare hands during the treatment, or it is accidentally put in the mouth. Therefore, it is not necessary to use rubber gloves or the like when treating synthetic fibers, and a normal plastic tank or the like may be used as a storage container.

  Synthetic fiber reinforcing agents of Formulation Examples 1 and 2 were prepared, and 12 cc of this synthetic fiber reinforcing agent was added to 3 liters of water and mixed with stirring. 6 pieces of women's pantyhose after dehydration were soaked in the above containers three by three, taken out after 8 minutes, squeezed and dried by shade drying.

The following tests were conducted on the obtained six stockings and an untreated stocking (comparative example) for comparison to confirm the treatment effect of reinforcement.
[Reinforcing effect test]
In a state where the stocking was stretched loosely, it was rubbed lightly using a jig and continued until a wire was generated in the untreated stocking as a comparative example.
As a result, even in the condition where transmission lines were generated in the untreated stockings, none of the six stockings treated with the synthetic fiber reinforcing agent was subjected to generation or breakage.
[Mountability test]
Each stocking was worn by six women, and the difference from the comparative example was individually judged.
As a result, in the stockings of the comparative example, transmission was generated when two women scratched the toenails when worn. Moreover, when the nail of each hand was put up in the state of mounting | wearing, the transmission line generate | occur | produced in the stockings of four women in the stockings of a comparative example.
However, no transmission wire was generated in the stockings treated under the same conditions.
Moreover, in the comparison with which the stocking processed with the said reinforcing agent for synthetic fibers and the comparative example were mounted | worn, six women reported having good wearing comfort and having antistatic property.

  It can be suitably used for synthetic fibers (particularly linear aliphatic polyamides having an amide group, such as a registered trade name; nylon) products such as stockings.
