Description
Technical field
The present invention relates to polyester fibre in differentiation technical field, specifically, is that the multi-functional compound of a kind of curtain imitates flax fibre and preparation method thereof.
Background technology
Terylene is an important kind in synthetic fiber, it is with p-phthalic acid (PTA) or dimethyl terephthalate (DMT) (DMT) and ethylene glycol (EG) for raw material is through esterification or ester exchange and polycondensation reaction and obtained high polymer-polyethylene terephthalate (PET), through the fiber that spinning and aft-loaded airfoil are made.Because of the physics and chemistry characteristic that it is excellent, be widely used in garment material and non-garment industry.
Curtain is the important component part of household soft decoration, along with daylighting effect is emphasized in the place such as local-style dwelling houses, office more, windowpane designs increasing, and jewelry can be subject to the irradiation of sunlight, ultraviolet effect and fade and degrade in curtain etc., affects the life-span of curtain.In addition, because textiles great majority have flammable properties, more and more become the hidden danger of fire, therefore, window curtain fabric more and more needs to possess uvioresistant, the performance such as fast light, fire-retardant.But the fiber of the window curtain fabric on current market or function singleness, given by the mode of Final finishing that it is multi-functional, patent CN102560728A discloses a kind of uvioresistant and flame-retardant polyster fiber and preparation method thereof and application etc., are all general fibres of anti-ultraviolet flame-retardant, the fabric of individual style can not be formed; Patent CN103726310A discloses a kind of production technology of anti-ultraviolet flame-retardant light-resistant curtain shell fabric, and give fabric uvioresistant and fire-retardant function by the method for Final finishing, this kind of method gives the function poor durability of fabric.
Summary of the invention
Give by the method for Final finishing the problem that fabric uvioresistant and fire-retardant function cause the function poor durability of fabric for solving curtain in the market, the invention provides a kind of multi-functional compound and imitate flax fibre and preparation method thereof, make its woven window curtain fabric not only have uvioresistant, the function such as fire-retardant, and there is good durability and imitative leprosy lattice and numb shape outward appearance.
The present invention is achieved by the following technical solutions: a kind of multi-functional compound imitates flax fibre, and it is 2.5 ~ 3.0cN/dtex that described multi-functional compound imitates flax fibre fracture strength, and elongation at break is 19 ~ 25%.
The preparation method that described a kind of multi-functional compound imitates flax fibre is following steps:
(1) preparation has the polyester drafted fibre FDY of uvioresistant and anti-flaming function;

Wherein, the mass ratio of ultraviolet screening mother granule and copoly type phosphorous flame-retardant Terylene fiber resin is 8 ~ 15:85 ~ 92.
As preferably, the first heat roller temperature is 85 ~ 105 DEG C, and the second heater temperature is 100 ~ 130 DEG C, and winding speed is 3800 ~ 4200m/min.
(2) using there is the polyester drafted fibre FDY of uvioresistant and anti-flaming function as core silk and sheath silk, carrying out false twisting Combined Processing, obtaining a kind of multi-functional compound and imitating flax fibre.
Wherein, the mass ratio of core silk and sheath silk is 40 ~ 60:40 ~ 60, is more conducive to adding carrying out smoothly of bullet, good through the fibre quality index adding spring-go conjunction, also according to the performance indications of customer requirement and appearance effect, can regulate the compositely proportional of two kinds of fibers.
Concrete steps are: by core silk through a roller, sheath silk core silk and sheath silk after zero passage roller are pooled capital, successively through a hot case, coldplate, false twister, two rollers, two hot casees, three rollers, oil tanker, last Wound-up roller coiling and molding, obtains a kind of multi-functional compound and imitates flax fibre.As preferably, draw ratio 0.97 ~ 0.99, roller/zero roller than 0.7 ~ 0.8, speed ratio 1.7 ~ 1.9, a heater temperature 200 ~ 220 DEG C, two heater temperatures 180 ~ 200 DEG C, silk speed 170 ~ 220m/min.
Core silk and sheath silk all have uvioresistant and anti-flaming function, make its fabric uvioresistant and fire resistance better; By two kinds of FDY by carrying out false twisting process on false twisting machine, make the composite fibre obtained have bamboo joint structure extremely closely, have the sense of touch of nature fiber crops, Shi Hou road weaving efficiency is higher, and fabric has imitative leprosy lattice and numb shape outward appearance preferably.
A kind of multi-functional compound of the present invention is imitated flax fibre and is taken into account uvioresistant and fire-retardant function, there is bamboo joint structure extremely closely simultaneously, naturally the sense of touch of fiber crops, can weave under running up, its fabric has imitative leprosy lattice and numb shape outward appearance preferably, is therefore the novel fibre in differentiation be useful in window curtain fabric.
Compared with prior art, the invention has the beneficial effects as follows:
(1) the present invention adopt polyester drafted fibre FDY all there is uvioresistant and anti-flaming function, the fabric anti-ultraviolet property of formation and fire resistance better than afterfinish method effect, durability is better;
Preparation method of the present invention is simple, and production equipment is general, is easy to suitability for industrialized production, has significant economic benefit and social benefit.
