Description
Technical field
The present invention relates to a kind of manufacturing methods of novel block copolymer mixture elastomer；And described in a kind of use
Novel block copolymer mixture elastomer made of manufacturing method；And the elastomer is in all kinds of textile fabrics or bullet
Application in the fields such as property cotton rope.
Background technique
In the elastomer used in weaving at present or elastic cotton rope field, spandex (scientific name " polyurethane elastomeric fiber ",
Including dry method spandex, Wet-process Spandex and melt spun spandex) it accounts for the market share close to 90% and occupies dominant position.But spandex exists
It is easy to aging degradation, easy fracture relaxation, containing hazardous solvent, it is not alkaline-resisting, chlorine-resistant drift, be not easy the defects of contaminating dark color.
In elastic cotton rope field, caused using conventional spandex fiber elastic cotton rope cannot persistently, under not ageing-resistant, intensity
The defects of drop, the body especially in the elastic cotton rope in professional domain (such as the fields such as outdoor sports, extreme sport, mountain-climbing cotton rope)
Reveal obviously defect, needs a kind of elastomer that stability and durability is anti-aging instead.
The polyolefin elastic fiber of tradition crosslinking is the Dow Chemical Company (Dow Chemical) in the new of release in 2002 or so
Type elastomer product, such elastomer are resistant to up to 220 DEG C of setting temperature, chlorine-resistant drift, strong acid-base, uvioresistant drop
Solution, flexible and can be low-temperature shaped, the usage and dosage in textile is also suitable with spandex, overcome spandex it is not ageing-resistant,
Chlorine-resistant does not float not alkaline-resisting disadvantage, is preferably a kind of elastomer of comprehensive performance.
But for polyolefin elastic fiber (based on made of POE) since its immanent structure is limited, elastic recovery rate is poor,
Elastic recovery rate after 300% stretching is generally below 85%, and elastic recovery rate is low after stretching than the 300% of common dry method spandex
Nearly 10% is even more, so that many fabric (such as underwears, swimming for needing normal rebound degree requirements can not be promoted the use of
Clothing, jean, gym suit etc.) in.
Meanwhile there are also some limitations through polyolefin elastic fiber made of electron radiation crosslinking, mainly: expensive irradiation
Expense increases the cost of fiber significantly；The irradiation of high dose can cause fiber to generate heat, may cause the mutual adhesion of fiber and
Unwinding is difficult；The polyolefin elastic fiber handled using electron beam irradiation has lacking for the irradiation dose uniformity difference for being difficult to overcome
It falls into, will cause in same spinning cake the difference on the Gel baits of fiber everywhere, eventually cause the fabric containing such elastomer
Cloth cover out-of-flatness.In addition, thermoplastic polyolefin elastomer becomes thermosetting polyolefin elastomer after being crosslinked, it is difficult to natural
Degradation, causes difficulty to circulation and stress.
In order to reduce the cost of production polyolefin elastic fiber, CN103361767B and CN103290509B are each provided
A kind of heat resistance is able to the manufacturing method of improved thermoplastic polyolefin elastomer.It is base that foregoing invention fiber, which is by propylene,
Mixed with polymers is process, and is not needed electronic crosslinking procedure of processing and crosslinking agent, is simplified manufacturing method.Foregoing invention fiber
Maintain the most of advantages for the polyolefin elastic fiber being traditionally crosslinked, heat resistance by polypropylene fusing point (160 DEG C~
169 DEG C) limitation, but also can reach 110 DEG C~150 DEG C, can meet most of textile fabric or elastic cotton rope dyeing,
The requirement of the normal process temperatures such as dry and thermal finalization.But the polyolefin elastic fiber that the invention fiber is crosslinked with tradition,
Since its immanent structure is limited, elastic recovery rate is poor, and the elastic recovery rate after 300% stretching is generally below 82%.This is heavy
It wants defect that the invention fiber is used in textile fabric to be above limited by very large.
It is well known that styrene block copolymer (SBC), which compares traditional polyolefin elastic copolymer (POE), to be had more preferably
Elastic recovery, and styrene block copolymer is also a kind of special polyolefin copolymers, the characteristics such as acid-fast alkali-proof
Much stronger than polyurethane elastomer.But the use temperature of styrene block copolymer is lower, mainly due to styrene
The glass transition temperature of styrene hard block in object at 95 DEG C or so, the normal use temperature that can bear 60 DEG C~80 DEG C with
Under.So the styrene block copolymer elastomer using produced in conventional processes cannot bear textile fabric or elasticity
The requirement of the normal process temperatures such as dyeing, drying and the thermal finalization of cotton rope can not directly apply to textile fabric or elastica
In the market in rope field.
In the elastomer used in weaving or elastic cotton rope field, polyester ether elastic fiber occupies a tiny space.
It passes through thermoplastic polyether ester elastomer (TPEE, also known as thermoplastic co-polymer ester elastomer) by Di Ren company first in nineteen ninety
Melt spinning.It is with crystallinity height, and the high polyester segment of fusing point is as hard section, with the lower nothing of glass transition temperature
Polyethers (being also possible to polyester) is shaped as soft segment, by chemically reacting the block copolymer being combined into.With elastic polyurethane
Fiber is compared, and polyester ether elastic fiber has excellent stability, oil resistivity, heat resistance, and (its minimum fusing point is not less than 170
DEG C), abrasion performance, chlorine-resistant drift property and can dyeability.But there is also some disadvantages for TPEE elastomer, such as its elongation at break
With elastic recovery rate still not as good as spandex, its degree for substituting spandex is limited.
