Abstract
The invention provides a formula of composite superfine fiber blending liquid. The composite superfine fiber blending liquid comprises nylon and modified polyester, wherein the modified polyester comprises the following components in percentage by weight: 5%-20% of isophthalic acid, 10%-30% of neopentyl glycol and the balance of polyethylene glycol terephthalate. Due to the adoption of the formula, crystals in polyester molecules can be reduced, the crystallization performance of the polyester can be degraded, the boiling shrinkage and the dry heat shrinkage of the polyester are improved, the proportion of added isomers can be adjusted within the weight part range provided by a specification according to different thermal shrinkage requirements, finished cloth treated through the composite superfine fiber blending liquid is very high in fineness, and the gram weight per square meter of the finished cloth can be increased by 30%-40% under the same specification.
Description
Technical field
The present invention relates to a kind of formula of composite ultrafine fiber blending liquid, relate in particular to the high formula that shrinks composite ultrafine fiber blending liquid of a kind of sliver type.
Background technology
Composite fibre is called again conjugate fibre, two kinds of components, consists of, and these two kinds of components can be polyester (PET), polyamide (PA), polypropylene (PP), polyethylene (PE), polystyrene (PS) and their modification high polymer.Compound form can be divided into according to cross sectional shape: cospinning type, parallel type, core-skin type, sliver type and the large class of fabric of island-in-sea type five.Composite ultrafine fiber is tender with its shrouding property of height, feel, it is comfortable to take, have the strong points such as outstanding adsorptivity and be generally used in clothes, senior artificial leather, absorption and filtering material etc., becomes the fiber species that enjoys people parent to look at.Composite ultrafine fiber is because filament number thin (being generally less than 0.33dtex), cross section abnormal shape, have higher wicking and gas permeability, make that its fabric feeling is tender, gloss is natural, thereby show the not available comprehensive imitated natural fabric function of synthetic fiber of other single variety.
Composite ultrafine fiber is to take conjugate spinning method spinning to form, its raw material is two kinds of inconsistent high polymers, its characteristic is in spinning process, two high polymer components are respectively via pooling specific cross-sectional shape in spinneret orifice porch after runner separately, through spinneret orifice, be squeezed into the fiber of convention fiber number, in rear machine process, again fiber two components peeled off and become the superfine fibre that single fiber is less than 0.33dtex.
Composite ultrafine fiber mainly contains two kinds of forms, and one is sliver type, and one is fabric of island-in-sea type.Composite ultrafine fiber can be divided into again long filament and two kinds of forms of short fiber, and technological principle is identical.An important use of composite ultrafine fiber is that in these two fields, sliver type composite ultrafine fiber is occupied an leading position as senior examination material and the polishing material wiped.Because ultra-fine single fiber cross section after opening fine separation is triangular in shape, while trying for wiping, can form " wedge shape " effect, can better wipe dust and the greasy dirt of clean body surface, be the senior cloth for wiping or dusting material of the industries such as accurate industry, electronic instrument, Motor Maintenance.With sliver type composite ultrafine fiber, manufacture polishing material and be mainly used in high-tech sector, as silicon, aluminium and CD manufacturing etc.Sliver type superfine fibre can obtain ultra-fine filament by fiber rupture via modes such as process mechanism, heating and solvents in rear machine process.But utilize merely on the market the fine and closely woven degree of the woven finished fabric of the common superfine fibre of sliver type of nylon and production of polyester not high at present, shrinkage is not good, can not bring into play well its optimum performance.
Summary of the invention
Not high for the fine and closely woven degree of the woven finished fabric of the common superfine fibre of sliver type in prior art, the problem that shrinkage is not good, the invention provides a kind of formula of composite ultrafine fiber blending liquid.
The object of the present invention is to provide a kind of formula of composite ultrafine fiber blending liquid, comprise nylon and modified poly ester, wherein, be weight percentage 5～20% M-phthalic acid of modified poly ester, 10～30% neopentyl glycol, surplus is polyethylene terephthalate.
Preferably, in the formula of composite ultrafine fiber blending liquid, the percentage by weight of modified poly ester and nylon is 55～80:20～45;
Preferably, in the formula of composite ultrafine fiber blending liquid, nylon is PA6 or PA66.
Adopt the formula of composite ultrafine fiber blending liquid of the present invention, in common polyester, add isomers M-phthalic acid and neopentyl glycol, reduce the crystallization composition in polyester molecule, reduce the crystal property of polyester, improve boiling shrinkage and the xeothermic shrinkage of polyester, the textiles that adopts the formula of composite ultrafine fiber blending liquid of the present invention to be made into, after arranging processing, can produce high density, in fabrics for industrial use, can produce the superfine fibre dust-free cloth of VHD, fill up the domestic blank of producing voluntarily of VHD non-dust cloth.
