Description

As a result of intensive studies to solve the above problems, the present inventors have found that the above problems can be solved if the fiber treatment agent has a specific phosphoric acid compound at a specific ratio, and the present invention has been completed. It was.
That is, the present invention is a fiber treatment agent for short fibers used for synthetic fibers for producing nonwoven fabric ,
Essentially contains a compound (A) represented by the following general formula (1), a compound (B) represented by the following general formula (2) and a compound (C) represented by the following general formula (3),
The weight ratio of the compound (C) in the nonvolatile content of the treatment agent is 1 to 35% by weight,
The weight ratio (C / (A + B)) of the total of the compound (A) and the compound (B) to the compound (C) is 0.01 to 0.5, and the weight ratio of inorganic phosphoric acid is 3%. percent a der Ru textiles treatment agent, an electrical conductivity of the concentration weight ratio of non-volatile content of 1% by weight of the treatment agent is less than 0 .mu.s / cm or more and 1300μS / cm, is a fiber-treating agent (However, the fiber processing agent which contains the component which consists of polyvinyl alcohol and / or its derivative as an essential component is excluded) .

It is preferable that the nonionic surfactant (D) is further contained, and the weight ratio of the nonionic surfactant (D) in the nonvolatile content of the treatment agent is 1 to 40% by weight.
The nonionic surfactant (D) preferably contains a polyglycerol fatty acid ester (D4).
It is preferable that the nonionic surfactant (D) contains a compound (D3) which is an ester obtained by blocking at least one hydroxyl group of a polyoxyalkylene group-containing hydroxy fatty acid polyhydric alcohol ester and a dicarboxylic acid with a fatty acid.
