Abstract

The invention relates to a colored non-conventional type polyester monofilament with stable size and preparing method thereof. The method comprises drying, de-watering, melting, squeezing, spinning, cooling to form, oiling, rolling, heating to extend and heat forming the polyester slice cospun master batch slice, checking to form product filament. Advantages of the invention lie in that preparation process is simple; filaments are even; leveling shade is even; fiber thickness is even, which can be widely applied in fiber window screen preparation and industrial field. The fabric is flat, whichis lucidus and flexible, high is rupture strength, low rupture extension to ensure stable size of the fabric. It is not easy to deform. Fabric rebound resilience is great. Creep deformation and relaxation phenomenon are fewer. Waste water has low volume shrinkage ratio. The invention is not easy to deform at high temperature, which improves stable performance. Surface of fabric is clean with no polyester nonomer deposit builder.

Description

【Technical field】 [0001] The invention relates to the field of fiber technology, in particular to a colored special-shaped dimensionally stable polyester monofilament fiber and a preparation method thereof. 【Background technique】 [0002] Since the advent of polyester in the 1950s, great progress has been made in the development of industrial applications. Due to its low heat shrinkage, polyester industrial yarn is widely used in the field of narrow-width fabrics such as filter cloth, sunshade cloth, tarpaulin, etc. The dry heat shrinkage of traditional low-shrinkage polyester industrial yarn is about 2 % or so, the polyester industrial yarn with this level of dry heat shrinkage is woven into cloth. After the coating heat treatment, the cloth surface shrinkage rate is large, the shrinkage is uneven, and the cloth surface is easy to cause unevenness, so it can only be used for narrow fabrics. Weaving. In recent years, due to the rapid development of membrane structural mate...
