Sliding cool fiber and preparation and application thereof

Abstract

The invention discloses sliding cool fiber and preparation and application thereof. The sliding cool fiber is skin-core structure complex fiber which uses chinlon as a core material and uses polyethylene as a skin material; the sliding cool fiber is prepared from the following raw materials by mass percentage: 30%-70% of the chinlon and 30%-70% of the polyethylene. The fiber filament is high in strength, good in toughness and stability, smooth and cool in hand feeling, can be used as a warp and a weft in spinning, and can be used for both of a shuttle loom and a shuttleless loom, the fiber filament can also be used for knitting fabric containing the sliding cool fibers, and the knitted fabric is good in wearability; a preparation method of the sliding cool fiber is improved on the basis ofan existing composite spinning technology of complex fibers, and the main improvement is that two melt distribution pipes are provided in a spinning manifold: a PA melt distribution pipe and a PE melt distribution pipe, wherein the length of the PE melt distribution pipe is 30%-40% shorter than the length of the PA melt distribution pipe, so that PE and PA, the two types of materials in large specific difference are guaranteed to be successfully compounded, the compact compounding of pure polyethylene and pure polyamide is realized, the operation is convenient, and the method is suitable forindustrial production.

Description

technical field [0001] The invention relates to the technical field of composite fibers, in particular to a slippery cool fiber and its preparation and application. Background technique [0002] Composite fibers are a type of multicomponent fibers. There are two or more polymer fibers that are not mixed on the same fiber section. This fiber is called a composite fiber. It is a physically modified fiber developed in the 1960s and can be used for fillers, fabrics, non-mixed Weaving cloth, medical and sanitary products and other fields. Bicomponent composite fibers or multicomponent composite fibers with the characteristics of two or more polymers can be obtained by using composite fiber manufacturing technology. Two-component composite fibers commonly used in the market include polyester (polyester and water-soluble polyester) composite fibers, polyester / nylon (polyester and nylon) composite fibers, polyester / propylene (polyester and polypropylene) composite fibers, and the ...

AI Technical Summary

Problems solved by technology

[0008] At present, in the prior art, there is no composite fiber filament composited with pure polyethylene and pure polyamide, mainly because polyethylene has low molecular weight, low melting point (melting point is about 135°C), and it will be carbonized after melting for a long time. Polymer: The properties of polyamides with high molecular weight and high melting point are very different, and the composite fiber filaments with composite fiber cannot be directly composited into composite fiber filaments with a skin-core structure without using any additives.
