Description

  The present invention relates to a fiber treatment composition containing emulsified particles.

Oils such as silicone compounds are applied to various fields such as cleaning agents, finishing agents, fiber treatment agents, lubricants, and the effects of improving the texture of objects are especially applied to finishing agents for textiles such as clothing. It is widely used for the purpose. In addition, many techniques that use an oil agent such as a silicone compound in combination with a polymer compound are also disclosed. Patent Documents 1 to 4 disclose fiber treatment agent compositions containing a water-soluble polymer compound and a silicone compound that are generally known as paste bases. Patent document 5 discloses a specific polysaccharide derivative, and it is described that the polysaccharide derivative of the patent document can stabilize a hydrophobic compound.

  In recent years, with the growing awareness of fragrance, a technique has been developed in which a fragrance persists even after washing is finished by using a fragrance having a residual fragrance as a cleaning agent for clothes and a finishing agent. Although these techniques generally use a fragrance that is relatively difficult to evaporate, it is not possible to selectively attach the fragrance to an object such as clothing. It is difficult to efficiently leave the scent on the clothes.

  Patent Documents 1 to 4 disclose a technique in which a water-soluble polymer compound and a silicone compound are used in combination, and these publications describe that a fragrance can be used.

  Patent Document 5 discloses a polysaccharide derivative modified with a long-chain alkyl group, and Examples of the Patent Document disclose a technique in which a polysaccharide derivative and a silicone compound are used in combination. However, this patent document aims to stabilize the solution of the silicone compound, and does not suggest any point that high residual fragrance can be imparted by using an oil agent such as a silicone compound and a fragrance.

  Therefore, the problem of the present invention is that the emulsion does not break even when an aqueous composition containing an oil agent and a fragrance mixture (oil agent component) is diluted with a large excess of water, and the oil component adsorbability to the target surface of a textile product or the like. An object of the present invention is to provide a fiber treatment agent composition capable of improving the fragrance and imparting high residual fragrance properties.
