Abstract

There is a Vinyl chloride-acrylonitrile copolymer fiber and fiber-glass coving yarn and its jet spinning preparation method. The characteristic of it is that the continuous fiber-glass yarn is the core line of the coving yarn, Vinyl chloride-acrylonitrile copolymer fiber homogeneously covered and twisted around the continuous fiber-glass yarn. This Vinyl chloride-acrylonitrile copolymer fiber and fiber-glass coving yarn is made by jet spinning preparation method. The technology processes are as fellows: the chloride-acrylonitrile copolymer fiber is through cleaning, scotching or firstly, secondly and thirdly drawing process, it is lonely made the strip of 2g / m-4g / m. Then the strip of Vinyl chloride-acrylonitrile copolymer fiber and the continuous glass-fiber yarn feed into the discharge nozzle of the jet spinning machine at the same time, the Vinyl chloride-acrylonitrile copolymer fiber and fibre-glass coving yarn can be coiled out from the second nozzle. Jet spinning preparation method is a new preparation method, and the feather of covering yarn formed by this method is short and rare. It has the ability to resist the forming of hair and hair bulb, and the outer fibre covers uniformly.

Description

technical field [0001] The invention relates to the field of cotton spinning engineering in the textile industry, in particular to an acrylic chloride fiber core-spun yarn with glass fiber as the core thread and a blending processing method thereof by air-jet spinning. Background technique [0002] Acrylic fiber is a kind of modified acrylic fiber, which is a kind of permanent flame-retardant fiber copolymerized by adding flame retardant to the conventional acrylic spinning solution, such as acrylonitrile and vinyl chloride or vinylidene chloride Fibers made by wet or dry spinning are a main direction for the development of high-performance fibers in this century. With the rapid and dense development of cities, fires occur frequently. Among various fire accidents, fiber textiles account for a considerable proportion. Fires caused by the burning of fiber products have become one of the major disasters in modern society, causing quite serious losses. , seriously threatening t...
