束性が高くなる。2. Description of the Related Art A yarn made of multi-filament which is not twisted is subjected to an entanglement treatment because it is difficult to handle because it has poor bunching property. In this way, the yarn fluid treatment device for performing the entanglement treatment on the yarn not imparted with the twist by the action of the fluid causes the yarn to be entangled to run between the pair of members, and ejects the fluid from one member. By doing so, an entangled portion and a spread portion opened in a spindle shape are periodically formed in the yarn, and as a result, it has the same degree as a twisted yarn with little or no twist. It is intended to impart focusing properties. Here, in the entanglement process applied to the yarn, the smaller the entanglement period, the higher the yarn converging property.
