Description

  The present invention relates to a fabric having perfume persistence for a laundry softener and / or detergent component containing a fragrance component and the use of the fabric.

  There is a growing demand to enjoy fragrances in daily life, and fragrances easily adhere to various textile structures such as cloth for clothes and bedding. However, research and development of fragrances with strong fragrances, fragrance prescriptions, and technologies for encapsulating fragrances have been made.

  In recent years, it has come to be preferred to add a fragrance during daily washing. The typical means is to use a detergent or softener that maintains a pleasant scent for a long period after drying, even if the cloth or clothing is in the middle of drying, with a laundry softener or detergent to which a fragrance has been added. That is. Many fragrance compositions applied to them have been invented.

  The invention on the perfume side is diverse and ambiguous, such as perfumes as perfumes, perfume formulations, softeners using them, detergents, washing-only perfume packages, post-washing spray-type perfume packages.

  When the consumer gives an advantage of giving a scent at the time of washing at home or the like, first, it is important that the desired favorite scent can be repeatedly given at every washing. Moreover, the point which can be reset to a different fragrance by changing into the clothing which provided the different fragrance | flavor is excellent. And it is important that the taste of fragrance in recent years tends to emphasize light fragrance. Flavors with light scent components often have low molecular weight and high volatility. In other words, perfumes and colons are premised on spraying directly onto the skin, and highly volatile perfume ingredients will volatilize immediately (top note, first impression of perfume for a few minutes), which will last for a long time. It was difficult to make use of it, and it was difficult to maintain a light and refreshing fragrance. The main functions of perfume and colon (middle note, base note, lingering scent of perfume) are said to be heavy and have a strong formal impression and tendency.

  However, no attempt has been made to meet this demand on the fabric side, which is an object to which fragrance is imparted. That is, there was no technical idea aiming at increasing the perfume adsorption rate by pursuing the improvement of the material on the fiber structure side so that the scent continues for a long time. In particular, there was no technical idea aimed at lasting a light scent for a long time.

  As an attempt close to this, there is an example in which a scent component, a deodorant component, or the like is added to a fiber or fiber structure at the time of production (Patent Document 1 and Patent Document 2). Moreover, patent document 3 is mentioned as an example of the fragrance | flavor base material used for an aromatic.

  That is, it has a specific fragrance from the beginning. Patent Document 1 and Patent Document 2 describe what imparts a fragrance to a fiber material during production. However, unfortunately, the scent has a very high palatability and is linked to individual sensibilities, and it is very uneconomical to prepare products exhibiting various scents in advance. And, when a specific fragrance is given in advance at the time of manufacture, when a consumer gives a favorite fragrance later at the time of washing or the like, the favorite fragrance cannot be obtained because the previously given fragrance remains, etc. The purpose of this case may be hindered. Furthermore, this method does not satisfy the above-mentioned requirement for resetting the repeated scent and the requirement for a light scent.

  To the best of the applicant's knowledge, there are reports of fragrances having fragrance persistence, but it has not yet been reported that a fabric having fragrance persistence has been obtained.
