Estimating the term…
According to the present disclosure, a polyamide composition that is less prone to clogging in the flow paths such as filters in a processing apparatus during melt processing such as melt spinning, and allows for long-term continuous operation of a processing apparatus can be provided. A polyamide composition is provided which is a recycled polyamide composition containing a silicon compound and having a silicon atom content as quantified by X-ray fluorescence analysis of 1000 ppm or less.
A polyamide composition comprising a silicon compound and having a silicon atom content quantified by X-ray fluorescence analysis of 1000 ppm or less.
A manufacturing method of a polyamide composition comprising dissolving a polyamide from a silicone-coated polyamide base fabric, the dissolving being carried out using a container with a structure to prevent a part that rotates by an external driving force during the dissolution from coming in contact with the silicone-coated polyamide base fabric.
A polyamide fiber having a content of polyamide components with a polymerization degree of 5 or less of 20000 ppm or less, and a silicon atom content quantified by X-ray fluorescence analysis of 50 ppm or more and 1000 ppm or less.
