The high-elasticity ultrafine polyester-polypropylene composite fiber obtained through the production method disclosed by the invention has good fiber properties of both the polypropylene fiber and polyester fiber and embodies the elastic functions of polyurethane and the Vistamaxx propenyl elastomer; shown by experimental tests, the elastic recovery ratio is 100% when the elongation percentage is 10%; and furthermore, the strength of the composite fiber reaches 7.5-8.0 cN/dtex.
Description
Technical field
The present invention relates to a kind of production technology of fiber, particularly a kind of high elasticity washs the third composite ultrafine fiber and production method.
Background technology
Wash the third composite ultrafine fiber often because limiting by the own material properties of polypropylene fibre and terylene, the elastic restoration ratio of composite fibre, by certain influence yet, does not often make elastomeric composite fibre, thus brings certain limitation to its application.
Summary of the invention
The object of the invention is to provide one both to have high elastic recovery rate to solve above-mentioned the deficiencies in the prior art, the high elasticity having again fiber self-characteristic concurrently washs the third composite ultrafine fiber and production method.
To achieve these goals, a kind of high elasticity provided by the invention washs the third composite ultrafine fiber, it comprises ultra-finely washs the third composite fibre, it is characterized in that described ultra-fine third composite fibre of washing is for heart yearn with superfine modified polypropylene fiber, outer cladding sex change polyester fiber layer forms, and described superfine modified polypropylene fiber heart yearn is containing 5 parts of Vistamaxx propylene-based elastomerics to 10 parts of weight portions in the polypropylene fibre melt of every 100 parts of weight portions; The core line diameter of superfine modified polypropylene fiber is at 0.1 micron to 1.0 microns, described sex change terylene is the silicon dioxide nano powder material containing 10 parts to 20 parts polyurethane melts and 2 parts to 5 parts in the melt of part terylene of 100 by weight, and the composite fibre diameter after coated is at 1 micron to 4 microns.
A kind of high elasticity washs the production method of the third composite ultrafine fiber, comprise and adopt high elasticity described above to wash the third composite ultrafine fiber, it is characterized in that 100 parts of terylene melts and 10 parts to the congruent melting of 20 parts of polyurethane melts, add the silicon dioxide nano powder material of 2 parts to 5 parts again, abundant dispersion is melted mutually evenly and is made sex change terylene, control temperature is at 260 DEG C to 280 DEG C, separately the polypropylene fibre melt of 100 parts of weight portions and 5 parts of Vistamaxx Propylene-based elastomers melt congruent meltings to 10 parts of weight portions are made improved polypropylene, and control temperature is at 300 DEG C to 320 DEG C; Then carry out wire drawing outside the heart yearn by conjugate spinning assembly sex change terylene being coated on superfine modified polypropylene fiber and form composite fibre; In drawing process, superfine modified polypropylene fiber core line diameter controls at 0.1 micron to 1.0 microns, and spinning temperature controls at 310 DEG C, and the spinning temperature of sex change terylene controls at 280 DEG C, and the composite fibre diameter control after coated is at 1 micron to 4 microns.
At this, Vistamaxx propylene-based elastomeric is commercial goods, is not described in detail it at this.Polyurethane fiber fracture strength is low, can improve its fracture strength after adding silicon dioxide nano powder material, improves its spinning properties.
The high elasticity that the production method that high elasticity provided by the invention washs the third composite ultrafine fiber obtains washs the third composite ultrafine fiber, by the setting of internal outer cladding structure, composite fibre had both had the good fiber characteristic of polypropylene fibre, there is again the good fiber characteristic of terylene, embody again the spring function of polyurethane and Vistamaxx propylene-based elastomeric, the composite fibre obtained thus has good high elasticity functional characteristic.Test by experiment, elastic recovery rate during percentage elongation 10% is 100%.And composite fibre intensity reaches 7.5cN/dtex to 8.0cN/dtex.
