Description
Technical field
The present invention relates to a kind of polyamide formed by hexamethylene adipamide/caprolactam copolymer and polycaprolactam to answer
Condensating fiber.
Background technique
Fypro is a kind of multipurpose fiber, has very extensive purposes, and the scope of application can be produced from clothes to industry
Product, such as fishing net, filter cloth, hawser, tire and parachute fabric etc..Fypro both can be used alone, can also be with it
His natural fiber or chemical synthetic fiber are used in mixed way, and fabric is made.Obtained fabric smooth, strong durable, valence with feel
The moderate feature of lattice.Demand with people to comfort level constantly enhances, and more novel Fypros gradually are replacing passing
The Fypro of system.Wherein, fabric made from the good Fypro of crimp property is because there is good snugness of fit, elasticity
And drapability, there is biggish demand in terms of women business wear, gym suit and easy dress.
In previous patent, the research of this fiber is also related to.Such as Chinese patent CN103882555A is disclosed
A kind of nylon composite fibre technology, be with long fatty carbon chain long-chain polyamide and polyether-modified polyamide through composite spinning
It is made.Section is parallel type or core shift type.Because the residualinternal stress of two components has bigger difference, this nylon is multiple
Condensating fiber energy spontaneous crimp, and its fabric has excellent elasticity, the flexible elongation without false twisting processing fabric is more than 95%.
But polyether-modified polyamide compares general polyamide, the cost is relatively high.
In addition, disclosing a kind of polyamide compound fibre in Japanese Patent Laid-Open 2001-159030, fracture morphology is arranged side by side
Perhaps a kind of ingredient of core shift type is that perhaps another ingredient of nylon66 fiber is nylon 610 or nylon 12 to nylon 6, obtained
Fiber has good performance of crispaturaing, and stretches elongation between 50~70%.Its flexible elongation is less than 80%, compares market
Upper existing some products, crimp property do not have clear superiority.
Summary of the invention
The purpose of the present invention is to provide a kind of with good crimp property and elastic polyamide compound fibre.
The technical solution of the invention is as follows:
A kind of polyamide compound fibre, the composite fibre are by component A hexamethylene adipamide/caprolactam copolymer and B group
Polycaprolactam is divided to obtain by composite spinning, the relative viscosity of component A is higher than the relative viscosity of B component by 0.50~2.00, excellent
Select the relative viscosity of component A higher than the relative viscosity of B component by 0.80~1.50.
In the component A, relative to hexamethyleneadipamide unit and caprolactam unit total amount, preferably hexamethylene adipamide
The content of unit is 10~80mol%, and the content of caprolactam unit is 90~20mol%.
The composite fibre is preferably parallel composite fiber or inclined core type composite fiber.
The weight ratio of component A and B component preferably 20/80~80/20 in the composite fibre.
After 90 DEG C of boiling water add 2mg/D loading to handle 20min, the flexible elongation of the composite fibre is 30%~
150%。
By that will have two kinds of polyamide of relative viscosity difference that composite fibre is made, so that fiber has good crimp property
With elasticity, the fabric as made from the fiber has good feel and flexibility, than general on windproof fabric or eiderdown shell fabric
Fiber is more advantageous.
Specific embodiment
Polyamide compound fibre of the present invention is obtained by component A and B component by composite spinning.Due between two components
It is poor that there are relative viscosities, to make to generate difference in shrinkage in fiber between both components, and then assigns the good crimp property of fiber
With elasticity.
Heretofore described B component is polycaprolactam, and the component A is to be copolymerized by hexamethylene adipamide and caprolactam
Obtained copolymer.Containing structural unit C as shown in Equation 1 and as shown in Equation 2 in the molecule segment of the component A copolymer
Structural unit D,
—HN(CH2)6NHCO(CH2)4CO-formula 1,
—NH(CH2)5CO-formula 2.
Relative to the total amount of structural unit C and structural unit D, the content of structural unit C is 10~80mol%, structural unit
The content of D is 90~20mol%.
Hexamethylene adipamide and caprolactam are amide system component, and the two associativity is good.And hexamethylene adipamide with
Shrinkage between caprolactam has notable difference, therefore the copolymer after being copolymerized has good shrinkage and contraction to answer
Power.When the too high levels of structural unit C or structural unit D in component A, it will lead to copolymer shrinkage and be partial to content height
Component, so that the shrinkage of copolymer becomes unobvious.It is advantageous to the content of structural unit C in component A be 10~
The content of 80mol%, structural unit D are 90~20mol%.
The relative viscosity of the component A is higher than the relative viscosity of B component by 0.50~2.00, when the differences in viscosity is greater than 2.0,
Component A and B component complex anomaly, not can be carried out spinning；When the differences in viscosity is less than 0.50, the crimp property of gained composite fibre
Difference, elasticity are unobvious.The differences in viscosity preferably 0.80~1.50.
Composite fibre of the present invention can be various types of composite fibres well known in the art, such as core-sheath-type, side by side
Type, core shift type etc., wherein parallel composite fiber and inclined core type composite fiber crimp property are the most obvious, and it is multiple that it is advantageous to parallel types
Condensating fiber and inclined core type composite fiber.
In composite fibre, preferably the weight ratio of component A and B component is 20/80~80/20.When the amount of component A is too many
When, the crimp property of composite fibre is unobvious, and when the amount of component A is very little, and polymer spues abnormal when spinning, and spinnability is poor.
Polyamide compound fibre of the present invention can be prepared by the following method:
Using parallel type, core shift type or other kinds of compound mouth gold, component A hexamethylene adipamide/caprolactam is copolymerized
Body slice and B component polycaprolactam slice are respectively fed to A, B feed inlet, multiple by spinneret after the melting of melt spinning machine
It closes and spues into silk.Through supercooling, oil supply step, polyamide compound fibre is obtained using FDY one step method coiling technique.
The FDY one step method technique of use, spinning speed are 1500~3000m/min, preferably 1500~2000m/
min；Elongating temperature is 20~90 DEG C, preferably 20~50 DEG C；Extension ratio is 1.0~3.0 times.
Polyamide compound fibre produced by the present invention has good performance and the elasticity of crispaturaing compared with common nylon.It will
The fiber is after 90 DEG C of boiling water add 2mg/D loading to handle 20min, and the elongation that stretches is 30%~150%, elastic recovery rate
60% or more；By the fiber after 60 DEG C of hot water processing 20min without load, the return rate that stretches is 20%~50%.By this
