no. 1 Embodiment approach
[0026] First, the first embodiment of the treating agent for viscose rayon nonwoven fabrics (hereinafter referred to as treating agent) embodied in the present invention will be described. The treatment agent of this embodiment (excluding the application as a cleaning or cleaning compound) contains the following polyhydric alcohols, the following fatty acids, and nonionic surfactants, and is attached to the viscose rayon fiber of the raw material fiber of the nonwoven fabric. use.
[0027] A polyol is a polyhydric alcohol having 2 to 6 hydroxyl groups in a molecule. These polyols may be used alone or in combination of two or more.
[0028] The fatty acid is a fatty acid having 12 to 24 carbon atoms. These fatty acids may be used alone or in combination of two or more.
[0029] The polyhydric alcohol used for the processing agent of this embodiment is a polyhydric alcohol which has 2-6 hydroxyl groups in a molecule|numerator as mentioned above. Specific examples of polyhydr...
no. 2 Embodiment approach
[0046] Next, a second embodiment of the actualized viscose rayon fiber of the present invention will be described. The viscose rayon fiber of this embodiment is a viscose rayon fiber to which the processing agent of 1st Embodiment adhered. As the adhesion method, known methods such as dipping, spraying, and roller methods can be applied. In addition, there is no particular limitation on the process in which the treatment agent is attached, and examples thereof include the post-process of the refining process, the textile process, and the like.
[0047] The form of the treatment agent when making the treatment agent of the first embodiment adhere to the viscose rayon can be, for example, an organic solvent solution or an aqueous liquid. The treatment method of viscose rayon is preferably to dilute the treatment agent of the first embodiment with water to an aqueous liquid with a concentration of 0.5 to 20% by mass, and the treatment agent of the first embodiment without solven...
Embodiment 1
[0058] The acid value, saponification value, and hydroxyl value of the treatment agent for viscose rayon nonwoven fabrics of Example 1 were measured in accordance with JIS K 0070.
[0059] Preparation of treatment agents for viscose rayon nonwoven fabrics (Examples 2-27 and Comparative Examples 1-5)
[0060] The processing agents of Examples 2-27 and Comparative Examples 1-5 were prepared in the same procedure as the preparation of the processing agent for viscose rayon nonwoven fabrics of Example 1. Among them, the types of polyols, fatty acids, nonionic surfactants, lubricating oils, and anionic surfactants used, and the content ratio (%) of each component in the treatment agent are shown in the "polyol" column, "fatty acid " column, "nonionic surfactant" column, "lubricating oil" column and "anionic surfactant" column are appropriately changed. The results of measuring the acid value, saponification value and hydroxyl value of the obtained treating agent according to JIS K...
