Abstract

The invention provides a polyarmide fiber package production method comprising the following steps: winding a polyarmide fiber filament bundle so as to obtain a polyarmide fiber package; using a nest-feed mode to wind. The method uses the nest-feed mode to wind, uses low speed winding polyester spinning equipment to stably spin the polyamide, thus reducing fund investment caused by reconstructing and redesigning the polyester spinning equipment, and greatly reducing production cost investment.

Description

technical field [0001] The invention belongs to the technical field of polyamide materials, and relates to a polyamide fiber package and a production method thereof. Background technique [0002] As an important textile fiber, synthetic fiber has surpassed natural fiber and has been widely used in various industries. Among them, polyester fiber (polyester), polyamide fiber (nylon) and polyacrylonitrile fiber (acrylic fiber) account for 90% of the total synthetic fiber output, while polyester fiber output is the first. [0003] Polyester fiber is a common fiber in the existing market. The spinning equipment used in the spinning process is relatively mature, and generally low-speed spinning is used for spinning. For example, CN102634859A discloses a polyester spinning and winding process, the winding is divided into multi-stage winding, but the highest winding speed is 3350m / min. Another example is CN1664185A, which discloses a production method for drawing polyester fibers....
