The effect of the size on the knittability of glass fibre is discussed in this paper.

In this paper, the causes of size migration and its effects on chopped strand mats are analyzed from aspects of raw material selection, fiber drawing process and fiber drying process.

Development of S-a size and its applied properties studied through three ways were introduced in this article, through which several conclusive remarks can be obtained.

Along a line of“applications of processed fiberglass products→requirements of these products for sizing agents→sizing agents used for these products”,this paper reveals the importance of single-purpose sizing agents in the system engineering of developing processed fiberglass products and introduces various types of sizing agents corresponding to various fiberglass products.

In order to reduce the ratio of emulsifier to the film former for sizing agent and increase the bonding strength between glass fibers and resin matrix,emulsions with small amount of emulsifier were produced by using high pressure homogenizing machine in emulsion processing.

This paper investigates the effects of different filament diameters and different sizing agents on the properties of high strength glass fibers drawn from 400-hole bushings and the composites made therefrom.
