Description

  The present invention relates to a fiber structure having a sleep improving effect and a method for producing the same, and more particularly, to a fiber structure having a sleep improving effect by applying cedrol to fibers, and a method for producing the same.

Conventionally, as a component having the effect of improving sleep, lavender, jasmine, chamomile, sandalwood and other fragrances are known, for example, a specific sleep-inducing fragrance composition including an Oris-based fragrance, sandalwood-based fragrance and rose-based fragrance Has been proposed (see Patent Document 1).
Also known are textiles and fabrics provided with an aroma component having an aromatherapy effect to heal a person's mind and body.For example, a natural plant essential oil having an aromatherapy effect is obtained via a retaining agent having an affinity with this. A comfortable comfortable fiber product (see Patent Document 2) supported on a fiber product, or a ceramic microporous body containing an fragrance is supported on cellulose fine powder, and the ceramic microporous body is replaced with the cellulose. An aromatic fabric made of a thermoplastic polymer fiber fixed to a fabric using fine powder as a medium (see Patent Document 3) has been proposed.

By the way, the fragrance component used in the above-mentioned fiber products and fabrics is a fragrance such as lavender, but since the fragrance has individual taste, even if the fragrance itself has an effect on sleep, it is used. Therefore, fiber products and fabrics that are effective with odorless substances are desired.
In addition, there is also a problem that a fragrance such as lavender gets used to the fragrance while being used, and its effect is weakened.

On the other hand, it is known that cedrol, which is a substance having substantially no odor or slight odor, instead of an aromatic component, has a sleep improving effect (for example, see Non-Patent Document 1).
However, a fiber product or a fabric containing cedrol to improve sleep has not been known so far.
Therefore, there is a need for textiles and fabrics that exhibit a sleep improving effect.

Hereinafter, the present invention will be described in detail for each item.
The fibrous structure having a sleep improving effect of the present invention is most characterized by containing cedrol.

1. Cedrol In the present invention, cedrol is used as a component having an effect of improving sleep. Cedrol is a tree component contained in Cedarwood oil (or Cedarwood oil), and can be obtained mainly by fractionating Cedarwood oil and recrystallization. The physical properties of cedrol are as follows: molecular weight (molecular formula: C ₁₅ H ₂₆ O): 222, melting point: 86 ° C., boiling point: 295 ° C. (150 ° C. ＠ 8 mmHg), white crystals, easily soluble in organic solvents. However, it is almost insoluble in water, has no odor, or has an extremely weak coniferous wood aroma, and is a kind of sesquiterpene alcohol.
In the present invention, the cedrol used is not particularly limited, and may be those extracted from cederwood (or cedarwood) (cedarwood oil or cedrol) as well as those extracted from other trees such as cedar or cypress (for example, cypress). Oil or cedrol). In addition, although there is no problem with these extracts, those having a high odor (for example, 99% or more) preferably have no odor.

  Cedrol and Cedarwood oil are known to be used as retaining agents such as soaps and detergent fragrances. In the present invention, cedrol is not a retentive agent but works on the parasympathetic nervous system of the human body and is superior to the sympathetic nervous system. It has a characteristic in that it is used as a device that exhibits a sleep improving effect. In the present invention, for the first time, when cedrol is contained in a cloth or a fibrous structure and used in bedding or pajamas such as sheets and covers, it has a sleep improving effect and a sedative effect, and is useful as a material exhibiting a sleep improving effect. It was found that. In particular, by making the material highly purified, making it less fragrant, and making it odorless, the effect is less likely to decrease due to key familiarization.

  In the fibrous structure having a sleep improving effect of the present invention, the content of cedrol is preferably 0.0001 to 1.0 part by weight based on 100 parts by weight of the fiber material. When the content is less than 0.0001 part by weight, there is no sleep improving effect, and when it exceeds 1.0 part by weight, the effect corresponding to the content is not exhibited.

2. Fiber Structure In the fiber structure having the sleep improving effect of the present invention, the fiber material to be used is not particularly limited, but preferably, cotton, thread, woven or knitted fabric, nonwoven fabric and the like are used.

Can be
The fiber material is appropriately selected according to the use of the fiber structure having a sleep improving effect of the present invention.

3. Cedrol fixing method (fiber structure manufacturing method)
In the present invention, the method of fixing cedrol, which contains or imparts cedrol to the fiber to obtain a fibrous structure having a sleep improving effect, is not particularly limited. Impregnating and drying the product, padding → drying → baking, and the like. In this case, it is preferable to use a resin processing agent (or a binder) in combination from the viewpoint of washing durability. Specific examples of the method include a pad / dry method and a dipping method using a jet dyeing machine or a drum dyeing machine. A pad / dry method using a tenter is preferred in terms of workability and cost. In this way, cedrol is contained in the fiber, and the form is such that cedrol is firmly attached to or exhausted from the fiber.
Further, a method of kneading cedrol at the fiber spinning stage or a method of post-processing in which cedrol is applied by spraying may be used.
Further, it can be processed and fixed by a printing method or a coating method using a resin or a paste containing cedrol.
Further, porous fine particles carrying cedrol can be fixed by a padding method, a printing method, a coating method, or the like. At this time, the porous microparticles supporting cedrol are produced by dissolving cedrol in a medium and supporting it on a porous body. The porous fine particles may be either inorganic porous fine particles or organic porous fine particles, but silica is preferred.
Further, microcapsules containing cedrol can be fixed by a padding method, a printing method, a coating method, or the like. The material of the microcapsules used here is not particularly limited, but a sustained release type (for example, porous silica or the like) is preferable.

  The pad / dry method is a method in which a pad (padder) for applying a drug or a processing agent to fibers, that is, a step of dipping a cloth in a drug and uniformly squeezing the fabric, and then a step of performing drying are performed. Generally, it can be carried out using a processing machine having these steps. The drawing ratio is preferably 50 to 150%, and the drying condition is preferably 100 to 140 ° C. for 30 seconds to 3 minutes.

In addition, in order to obtain washing durability, it is preferable to use, for example, an acrylic resin or a polyurethane resin as a resin processing agent (processing agent or binder) when applying cedrol to the fiber. Further, a softener may be used in combination for adjusting the feeling.
At that time, the amount of the resin processing agent to be used is 0.01 to 10 parts by weight, preferably 0.01 to 5 parts by weight, based on 100 parts by weight of the fiber material.
Specific examples of the acrylic resin processing agent include "Light Epoch T-23M" manufactured by Kyoeisha Chemical, and examples of the polyurethane resin processing agent include "Parazol PN-" manufactured by Ohara Palladium. 14 "and" Parazol PN-20 ".
In addition, in order to obtain washing durability, in addition to the pad / dry method described above, baking, that is, a step of thermally reacting a processing chemical may be further performed. The reaction of the processing agent is carried out at 140 to 180 ° C for about 30 seconds to 5 minutes, preferably at 150 to 160 ° C for about 2 to 3 minutes.
