Description

The present invention uses functional ingredients that exert functions on the skin or the body upon contact with the skin, such as ingredients such as hydrolyzed sericin purified from silk (cocoons, silk thread), sericin powder sericin, and fibroin. It can be imparted to fibers (fibers of textile products that come into contact with the skin) with a weak force, so that, for example, this sericin can be gradually removed and brought into contact with the skin that touches the fibers, for example, not only improving the feel of the fibers, but also New functional post-washing agents (fabric softeners), new functional immersion agents for textiles, and new functional spray agents (spray type) that can exert functions such as moisturizing and deodorizing effects on the skin that touches the fabric. The present invention relates to a functional ingredient-imparting agent for fibers such as an improving agent for fibers.

Silk has been used in the field of clothing for a long time as a luxury material because it is not only beautiful and pleasant to the touch, but also has excellent breathability and moisture permeability. Since is a protein composed of several types of amino acids, it is being used as a functional ingredient in fibers to take advantage of its functions and characteristics, and is also being used in cosmetics, foods, and other non-clothing fields. .

For example, sericin is known to have functions such as moisturizing effect and deodorant effect due to its antioxidant effect. Furthermore, research and development of functional textile products having a protein layer formed on the surface by sericin have been advanced. (Patent Document 1)

However, it is not easy to apply such a surface treatment to textile products and form a sericin protein layer. There were problems such as not being able to expand.

On the other hand, when sericin is applied to textile products at a factory as described above, it is applied to the fiber with a strong binding force (strong adsorption force or strong binding force), so it is necessary to wash it several times. This sericin does not easily come off even after being exposed to the heat, but conversely, although the function of the fiber itself can be improved by sericin, it cannot be expected to have a direct functional effect on the skin covered with the fiber.

On the other hand, if the sericin is imparted to the fiber with a weak binding force, the sericin is easily removed by washing, resulting in a one-time functional fiber product, which is further inferior in cost-effectiveness and further reduces the commercial value. As a result, the current situation is that it lacks practicality and cannot be widely used. Therefore, in the first place, there was no idea of gradually exfoliating and contacting the skin with a functional ingredient to exert a direct function on the skin or the body.

JP 2012-26054 A

The present invention solves such problems, and includes a softening agent (finishing agent) for imparting properties such as flexibility to fibers after washing, an immersion imparting agent for diluting and immersing and imparting to fibers, Focusing on spray-imparting agents, instead of strongly imparting sericin to textile products at the factory, functional ingredients such as sericin and fibroin can be easily imparted by simply adding or spraying during rinsing after washing. In addition, cationic polymers such as cationic chitosan derivatives and functional ingredients in solution (for example, sericin) are electrostatically adsorbed or adhered (bonded by light ionic bonds, so to speak), which are electrostatically adsorbed or adhered to fibers. By electrostatically adhering (so to speak, attaching by light ionic bonding), the functional ingredient can be attached to the fiber with a light binding force, so the binding (adsorption) between this functional ingredient and the fiber is weak. While having durability (function maintenance) to the extent that it can withstand repeated washing, the functional ingredients can be released to the skin appropriately and can be brought into contact with the skin, so that it has a moisturizing effect on the skin and body. It is possible to exhibit functions such as deodorant action, for example, by repeatedly applying an appropriate amount such as pouring or spraying an appropriate amount every several times of washing, the function of the functional ingredient can be exhibited on the skin and body through the fiber. It is an epoch-making functional ingredient-imparting agent for textiles, which is extremely practical such as being able to achieve excellent cost-effectiveness.

It will be an epoch-making functional ingredient imparting agent for fibers with excellent practicality.

A preferred embodiment of the present invention will be briefly described by showing the operation of the present invention.

A functional ingredient that exerts a function on the skin or body when it comes into contact with the skin, such as hydrolyzed sericin purified from silk (cocoon, silk thread), and this sericin is electrostatically adsorbed or electrostatically attached (so to speak, weak ion and a cationic polymer (for example, a cationic chitosan derivative that bonds with hydrolyzed sericin by this weak force), and is applied to the fibers after washing containing moisture, for example. An agent (softener or finishing agent), an immersion imparting agent that is diluted with water and immersed to impart to the fibers, or a spray imparting agent that is sprayed to impart to the fibers.

For example, the product of the present invention configured as a softening agent is applied to fibers containing water after washing (textile products to be washed). Specifically, when an appropriate amount is poured into the washing tub during rinsing after washing, the cationic polymer (for example, cationic chitosan derivative) bound to the hydrolyzed sericin is electrostatically adsorbed or adheres to the fibers. By (so to speak, attaching by weak ionic bond), the sericin is imparted to the fiber through the cationic polymer with a weak binding force.

This functional component (for example, sericin) binds to the cationic polymer with such a weak force, and this cationic polymer also binds to the fiber with a weak force, so that the fiber to which this functional component is imparted can be obtained. Upon contact with the skin, the functional ingredients are gradually released from the fibers and come into contact with the skin.

That is, the functional component having a negative charge or a negative polarity has a negatively charged surface or a negative polarity through the cationic polymer that is positively charged or has a positive polarity. can be applied to the fibers having a weak bond.

Moreover, since this functional ingredient is weakly bound to the fiber and the cationic polymer as described above (because it is bound and attached by a weak force, so to speak, weak ionic bond), it can be washed off several times. However, by contacting the fibers with the skin during this period, the functional ingredients are gradually separated from the fibers, and the functional ingredients separated from the fibers can be brought into direct and gradual contact with the skin.

Therefore, for example, functions such as moisturizing action and deodorant action can be exerted on the skin in contact with the fiber, and the effect can be imparted to the skin.

Therefore, it is possible not only to improve the flexibility and feel of the skin, but also to exert a predetermined function on the skin through the fibers, by simply applying it to the fibers moderately and repeatedly, for example, by pouring an appropriate amount every several times of washing. Functionality for textiles, such as epoch-making new functional post-washing agents (softening agents for fabrics), new functional soaking agents for textiles, and new functional spraying agents (spray-type fabric improvement agents), etc. A component imparting agent can be realized.

A specific embodiment 1 of the present invention will be described.

In this example, a functional component that exerts a function on the skin or the body when in contact with the skin and a cationic polymer to which the functional component electrostatically adsorbs or adheres is included.

Specifically, it is possible to impart functional ingredients such as sericin and fibroin from hydrolyzed sericin and sericin powder refined from silk (cocoons, silk threads) to fibers (fibers of textile products that come into contact with the skin) with a weak force. For example, sericin, which is a functional ingredient, can be gradually removed from the skin that touches the fiber and can be brought into contact, for example, not only improving the texture of the fiber, but also moisturizing and deodorizing the skin that touches the fiber. function (sericin function) can be exhibited as a new function after washing imparting agent (softening agent for fabrics), a new functional soaking imparting agent for textiles, or a new functional spraying imparting agent (spray type fiber improvement agent). It is used as a functional ingredient imparting agent for fibers that can be configured as

That is, in the present embodiment, a product that is applied to the fibers after washing containing moisture as a post-washing imparting agent, a product that is applied to the fibers after being diluted with water and immersed as an immersion imparting agent, or a spray imparting agent that is sprayed. For example, by applying the post-washing imparting agent to the fibers after washing containing moisture, the cationic polymer is electrostatically adsorbed or adhered to the fibers. The functional ingredient is imparted to the fiber through the cationic polymer, and the fiber and the skin come into contact with each other, so that the functional ingredient is gradually detached from the fiber, and the detached functional ingredient is It is constructed so that it gradually comes into direct contact with the skin and exhibits the above functions.

Specifically, the functional ingredient of the present embodiment imparts softness and good touch to the fibers, and when it is released and comes into contact with the skin, the above functions (sericin function) such as moisturizing action and deodorant action are exhibited. It is hydrolyzed sericin, which has a good effect on the skin (moisturizing effect, deodorizing effect, etc.).

That is, in this embodiment, the composition includes hydrolyzed sericin as the functional component and a cationic polymer to which the sericin electrostatically adsorbs or adheres electrostatically.

Therefore, in this example, by applying it to the fibers after washing containing moisture as a post-washing imparting agent (for example, as an immersion imparting agent, it is diluted with water and immersed and applied to the fibers, or as a spray imparting agent When the cationic polymer is electrostatically adsorbed or adhered to the fiber by spraying and applying it to the fiber, the sericin, which is the functional component, is attached to the fiber via the cationic polymer. is imparted, and since the fibers come into contact with the skin, the sericin is gradually detached from the fibers and comes into contact with the skin to exhibit the above functions.

Specifically, sericin, which is the functional component that is negatively charged or has a negative polarity, is transferred to the fiber by moisture through the cationic polymer that is positively charged or has a positive polarity. and is adapted to be applied to said fibers whose surfaces are negatively charged or have a negative polarity.

In addition, the functional component of the present embodiment binds the cationic polymer by weak electrostatic adsorption or electrostatic adhesion to the extent that the fibers come into contact with the skin and are separated from the fibers by washing at home several times. It is configured to be imparted to the fibers through.

Specifically, for example, when it is configured as a softening agent, water is applied to textile products such as underwear, socks, towels, etc. The hydrolyzed sericin is imparted to the fiber by diluting it to , for example, after washing such textile products at home or by a laundry company (for example, in the washing tub during rinsing after washing). When an appropriate amount of the product (softener) of this example is poured into is applied to the fiber whose surface is negatively charged or has a negative polarity.

That is, the cationic polymer that forms a complex with the hydrolyzed sericin and is bound to the fiber is electrostatically adsorbed or electrostatically adhered to the fiber (so to speak, adhered by a weak ionic bond). The fiber is configured such that the sericin is imparted with a weak binding force.

Therefore, the sericin is weakly bound to the cationic polymer, and the cationic polymer is also weakly bound to the fiber. The composition is such that sericin is gradually separated from the fibers and is imprinted on the skin little by little.

Moreover, in this example, by adding hydrolyzed sericin and a cationic polymer to the surface of the fiber in this way, the frictional resistance of the surface is reduced and the surface becomes soft and the softening effect is exhibited. A cationic oil component is added to enhance the effect. A cationic surfactant may also be added like a general softening agent.

Further, in the present embodiment, as described above, sericin is gradually removed by contacting the fibers with the skin, and sericin is gradually imprinted on the skin with a weak binding force, or after washing several times, for example. The sericin is imparted to the fibers through the cationic polymer with such a weak binding force (by electrostatic adsorption or electrostatic adhesion) that sericin is almost completely detached from the fibers.

Specifically, it is stored in a softener storage box for automatic injection of softener in an automatic washing machine in the same way as normal softener when washing about once every three times instead of every wash. It is a softening agent that is automatically put into the washing tub when rinsing, and it will fall off after several washes due to the weak bonding force described above, but until then, wearing this textile product (with this fiber When it comes into contact with the skin), sericin is gradually released from this fiber and sericin gradually comes into contact with the skin. It is composed of a softening agent that exhibits a new function that can give sericin function, which suppresses breeding, suppresses the smell of sweat, suppresses rashes, and keeps the skin clean and deodorant, to the skin that comes into contact with the fabric.

Therefore, for example, by simply pouring an appropriate amount every few times of washing, it is possible not only to repeatedly increase the flexibility of the fibers (improve the feel of the skin), but also to repeat the sericin function (new function) through the fibers. It becomes a softening agent that can be applied to the skin.

In addition, in this embodiment, such an epoch-making action and effect, that is, it can be imparted to fibers by a simple method (for example, by simply using it at home when washing), and it can be imparted to fibers with a moderately weak binding force. By moderately (gradually) withdrawing sericin from the skin, sericin can continue to exert its function, and the skin can be given the effects of functions such as moisturizing effect by sericin and deodorant effect by antioxidant action. It is possible to realize a softening agent with a novel new function (it is possible to realize the application of sericin with a weak bond).

In this example, the cationic polymer that can realize such a softening agent was discovered. By repeating the experiment, it was found that among the cationic polymers that achieve this effect, the coating system We found a cationic chitosan derivative that is excellent in moisturizing and softening effects, and that forms a complex with hydrolyzed sericin and attaches sericin to fibers with the aforementioned weak binding force. It is configured to

In other words, the combination of hydrolyzed sericin, which is a natural moisturizing material, and a cationic chitosan derivative has been combined to create a moist, soft, silky texture (reduce friction on the skin and create a smooth texture). In addition, it is constructed so that sericin can be gradually imprinted into the skin while being worn to impart effects of the sericin function such as moisturizing effect and deodorizing effect on the skin. If sericin is simply added, it will come off after just one wash, but with the double formulation with the cationic chitosan derivative, the sericin will be moderately removed from the fibers and will be imprinted on the skin little by little just by wearing it. As a result, a new functional softening agent that can continuously provide the skin with a moisturizing effect and an antibacterial and deodorant effect has been realized. (For example, after using the softener of this embodiment, even if you wash several times without this softener, the action and effect will continue, and if you use the softener again, this action and effect can be continued repeatedly. is a thing.)

More specifically, in the present example, liquid hydrolyzed sericin extracted by placing cocoons in water and heating at high temperature and high pressure in a pressure cooker (or by dissolving dried sericin powder) was added. , 1 to 30%, and 0.1 to 5.0% of a cationic chitosan derivative (e.g., chitosan isostearamide hydroxypropyltrimonium chloride). Tea catechin that enhances antibacterial properties, glycerin and glycol that further enhances moisturizing properties, and fibroin (with water) as a functional ingredient that is refined from cocoons and silk threads similar to sericin and is gradually imprinted on the skin to give the skin a skin repair effect. It is configured to contain decomposed fibroin).

Also, as described above, it is not constituted as a softening agent, but is diluted with water, for example ten times diluted, and the textile product is soaked in this for a predetermined time and squeezed to dry. Alternatively, the functional component can be imparted to the fiber with a weak bond by simply diluting the component and water content by 10 times with alcohol, making it into a mist with a sprayer, and drying it. It may be configured into a product that can be As a result, silk products, for example, are not only expensive but also difficult to handle, such as washing. Even if there is, it will be possible to easily give the touch and texture of silk, and silk functions to the skin.

It should be noted that the present invention is not limited to this embodiment, and the specific configuration of each component can be appropriately designed.
