1. invention field
The present invention relates to a kind of island polyester conjugate fibre capable of deep dyed and preparation method.More particularly, the present invention relates to following island polyester conjugate fibre capable of deep dyed and preparation method, described polyester conjugate fiber is preparation like this: use and count 1 to 10mole% cyclohexane 1 with the diol component of first copolyester polymer, first copolyester polymer that the combined polymerization of 4-dimethanol obtains is as island component, second copolyester polymer of Yi Rong is as sea component, and described second copolyester polymer is made by combined polymerization metal organic sulfonate, M-phthalic acid and polyethylene glycol.
2. description of related art
Fabric of island-in-sea type polyester conjugate fiber is a kind of high added value fiber, can be applied to senior flimsy material, dermatine or senior imitative chamois leather clothes, and people have proposed the multiple method for preparing fabric of island-in-sea type polyester conjugate fiber.Yet what these method great majority were described is to utilize to transform sea component production fabric of island-in-sea type polyester conjugate fiber, but few transformation of describing the island component.
People have made some and have attempted transforming the island component.For example, Korean Patent is not examined open 1998-055563 and is disclosed a kind of method of utilizing inorganic particulate to prepare island polyester conjugate fibre capable of deep dyed, and Korean Patent is not examined the preparation method that open 2002-48331 has told about the solution dyeing fabric of island-in-sea type conjugate fibre with high color fastness.
Yet, the preparation method of above-mentioned island polyester conjugate fibre capable of deep dyed utilizes inorganic silicon dioxide or titanium dioxide to form defective on the polyester conjugate fiber surface, the shortcoming of this method is, in preparation superfine yarn process, because the gathering of inorganic silicon dioxide or TiO 2 particles has undesirably reduced spinning workability.In addition, the fabric of island-in-sea type solution dyeing conjugate fibre that utilizes carbon black to make only has a kind of color, therefore is difficult to the conjugate fibre of solution dyeing is applied to various fields.
In addition, the monofilament of fabric of island-in-sea type polyester conjugate fiber is too thin, and can not carry out engrain to fabric of island-in-sea type polyester conjugate fiber according to the normal dyeing method.In addition, because after the stock-dye of fabric of island-in-sea type polyester conjugate, it has low adhesive property to dyestuff, so its COLOR FASTNESS reduces.
The invention summary
The present invention keeps the problems referred to above that occur in the prior art firmly in mind, therefore the purpose of this invention is to provide a kind of fabric of island-in-sea type polyester conjugate fiber and preparation method thereof, and wherein the amorphous area of island component becomes big, so that fabric of island-in-sea type polyester conjugate fiber can be by engrain.
DESCRIPTION OF THE PREFERRED
The present invention utilize predetermined polymer as sea component and island component to reach above-mentioned purpose of the present invention.
According to the present invention, utilize a kind of copolymer as the island component, so that fabric of island-in-sea type polyester conjugate fiber can be by engrain, it has a structure that can enlarge its amorphous area in theory, and does not reduce glass transition temperature, therefore guarantees to have improved COLOR FASTNESS.
The monomer example that is used to prepare the island component comprises aromatic series or alicyclic compound, as the ethene addition product or the cyclohexane 1 of naphthalene dicarboxylic acids, bisphenol-A, 4-dimethanol.
Particularly, consider the contraction of economic benefit and the raw yarn that utilizes monomer to make, the present invention utilizes cyclohexane 1, and the 4-dimethanol is as monomer.
Cyclohexane 1,4-dimethanol may exist isomeric forms such as cis-isomer and transisomer.Therefore, when utilizing cyclohexane 1, the 4-dimethanol is during as the monomer of preparation island component, even compare cyclohexane 1 with other monomer, 4-dimethanol consumption is less, and the amorphous area of island component is also sufficiently enlarged.
According to the present invention, the island component is 1 to 10mole% cyclohexane 1 in order to the diol component meter content of island component, and 4-dimethanol (being called " CHDM " hereinafter) combined polymerization obtains.
When using the CHDM that surpasses 10mole% to prepare the island component, the fiber that utilizes this island component to make has very high shrinkage factor.Particularly, when using the CHDM that surpasses 30mole% to prepare the island component, the amorphous area of this island component becomes excessive and can not utilize it to prepare fiber.
On the other hand, when the CHDM that is lower than 1mole% when use prepares the island component, just can not reach the purpose that the present invention increases island component amorphous area.
Sea component must have very high rate of dissolution in alkaline solution.Therefore, used easy the to be molten copolyester polymer mentioned among the korean patent application 2003-0026652 as sea component among the present invention.Here, the copolyester polymer of Yi Rong is to prepare like this: will with the diacid of copolyester polymer count 1 to 6mole% two hydroxyethyl isophthalic acid esters that contain metal sulfonate, with the diacid of copolyester polymer count 0.01 to 5wt% M-phthalic acid and with copolyester polymer count 3 to 15wt% and mean molecule quantity be 1,000 to 20,000 poly alkylene glycol combined polymerization.
According to the present invention, copolyester polymer utilizes the TPA polymerization to use terephthalic acid (TPA) (being called " TPA " hereinafter) to make as raw material.In addition, the preparation method of copolyester polymer can be divided into: utilize TPA as a kind of method of raw material with utilize the another kind of method of dimethyl terephthalate (DMT) as raw material.Wherein, in view of economic benefit, utilize TPA to have very much competitiveness as the method for raw material.
Contain in the method for copolyester polymer of CHDM in preparation, unreacted TPA is insoluble and molten.Therefore, unreacted TPA has stopped up the oligomer filter or the polymer filter of polymerization unit, perhaps when the copolyester polymer spinning, stuffing pressure increases fast owing to unreacted TPA, causes the reduction of processability in the manufacture process of copolyester polymer and fiber.
Therefore, necessary long enough of esterification time and esterification temperature must be fully high, to reduce the amount of unreacted TPA.
Yet, when very long or esterification temperature is very high when esterification time, increased unfriendly, thereby reduced the heat endurance of copolyester polymer as the output of the DEG of accessory substance.Therefore, preferably reduce the G value ratio of the molal quantity of terephthalic acid (TPA) (total mole number of ethylene glycol and CHDM with) as much as possible, to suppress the generation of DEG.According to the present invention, the G value is in 1.10 to 1.50 scopes.When the G value was in above-mentioned scope, the DEG content in copolyester polymer was 0.7 to 2.0wt%, has realized that thus the present invention increases the purpose of copolyester polymer amorphous area.Here, the hot property of copolyester polymer does not reduce, and therefore utilizing copolyester polymer to prepare in the process of copolyester fiber, does not go wrong in false twisting technology.
Because being mainly used in, copolyester polymer according to the present invention produces the clothes fiber, thus the same with normal polyester, can in copolyester polymer, add anatase titanium dioxide.
Specifically, when the bright fiber of preparation ultraphotic, in copolyester polymer, do not add anatase titanium dioxide.Yet when preparation lustrous fibre, semi dull fibre and full-dull fiber, the amount of the anatase titanium dioxide that adds in copolyester polymer is respectively 200 to 500ppm, 1,000 to 5,000ppm and 10,000 to 40,000ppm.
In addition, can add barium sulfate in copolyester polymer, be 5wt% or still less in its addition of copolyester polymer weight, improving the proportion of copolyester fiber, or improves the transparency and the frictional behaviour of copolyester fiber.
The example of polycondensation catalyst comprises that antimony-based catalyst such as antimony trioxide and antimony acetate, germanium are catalyst based as germanium dioxide and Ti-base catalyst such as butyl titanate and tetraisopropyl titanate.
In copolyester polymer weight, the amount that is used to prepare the polycondensation catalyst of copolyester polymer is 0.01 to 5wt%.
According to embodiments of the invention and comparing embodiment, the physical property of raw yarn sample is measured according to following method.
