Description
Technical field
The utility model relates to textile technology field, particularly relates to a kind of core silk being applicable to air-jet eddy-current spinning elastic force composite yarn and producing.
Background technology
In air-jet eddy-current spinning yarn production process, rove is entering air-jet eddy-current cup inside after drawing-off, and traditional method polyurethane elastic filament is introduced cup to form elastic force composite yarn; Polyurethane elastic filament has good elasticity, and elastic modelling quantity is low, and the elastic response time is short.But polyurethane elastic filament is used for the production of vortex spinning cladded yarn, after it enters cup, because larger air-flow draw, it is interval that polyurethane elastic filament will be stretched to maximum flexibility elongation fast, and very easily rupture, spinning efficiency is very low.
Elastic force long filament is together introduced cup with the fibre bundle be drawn through and is formed elastic force composite yarn by the utility model.The utility model adopts T400 long filament as the core silk raw material of vortex spinning elastic force composite yarn, its larger elastic modelling quantity and longer elastic response time, make it before spinning process completes, not yet reach the limit of drawing-off situation, meet the requirement that air-jet eddy-current spinning produces elastic force composite yarn.In addition, owing to adopting T400 to be core silk, reduce the requirement to the production and processing of T400 long filament, long filament production and processing efficiency can promote.
Utility model content
The purpose of this utility model is to provide a kind of core silk being applicable to air-jet eddy-current spinning elastic force composite yarn and producing, and solves the problem that traditional polyurethane elastic filament is easily pulled off, can reduce production requirement, improving production efficiency.
The technical scheme that the utility model adopts for its technical problem of solution is:
Be applicable to the core silk that air-jet eddy-current spinning elastic force composite yarn is produced, it is characterized in that: comprise core silk and be wrapped in the outer layer fiber in outside of described core silk by air-jet eddy-current spinning process;
Described core silk is T400 elastic force long filament;
Described outer layer fiber is the fibre bundle through traction; Described fibre bundle is the fibre bundle adopting viscose, tencel fiber or Modal fibre to make.
Wherein, the elastic response time of described T400 elastic force long filament is t1; Described t1 >=5 millisecond.
Wherein, the specification of described T400 elastic force long filament is 1.50D/32F, 2.75D/32F, 3.40D/32F, 4.100D/32F or 5.150D/32F.
The utility model has the advantage of:
The core silk being applicable to air-jet eddy-current spinning elastic force composite yarn and producing of the present utility model, is characterized in that: comprise core silk and be wrapped in the outer layer fiber in outside of described core silk by air-jet eddy-current spinning process; Described core silk is T400 elastic force long filament; Described outer layer fiber is the fibre bundle through traction; Described fibre bundle is the fibre bundle adopting viscose, tencel fiber or Modal fibre to make;
Described T400 elastic force long filament possesses larger elastic modelling quantity and longer elastic response time, makes it before spinning process completes, still also not arrive its ultimate draft situation, meets the requirement that air-jet eddy-current spinning produces elastic force composite yarn; Reduce the requirement to the production and processing of T400 long filament, T400 long filament production and processing efficiency can promote; Adopt spandex as compared with core silk with tradition, production efficiency significantly promotes, and board efficiency rises to more than 95% by 80%.

Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with diagram and specific embodiment, setting forth the utility model further.
Composition graphs 1 and Fig. 2 are described in detail to the core silk being applicable to the production of air-jet eddy-current spinning elastic force composite yarn of the present utility model.
Spandex core-spun yarn, in air-jet eddy-current spinning spinning process, the elastic modelling quantity lower because of it and faster elastic response time, easily ruptures in production process; After core silk enters cup, produce huge tractive force, and common spandex thread rigidity is lower, easily produce larger elongation instantaneously and break end, production efficiency is low, and spinning efficiency is less than 80%; Need to seek the more rational core silk of one, make vortex spinning can production and processing elastic force composite yarn; The utility model adopts T400 raw material as suitable core silk, adopts T400 as core silk, then has certain rigidity, can not draftedly rupture within the time of having spinned, therefore spinning can be completed, spinning efficiency more than 98%, and appropriateness reduces the processing request of T400 elastic force long filament.
The core silk being applicable to air-jet eddy-current spinning elastic force composite yarn and producing of the present utility model, is comprised core silk and is wrapped in the outer layer fiber in outside of described core silk by air-jet eddy-current spinning process;
Described core silk is T400 elastic force long filament;
Described outer layer fiber is the fibre bundle through traction; Described fibre bundle is the fibre bundle adopting viscose, tencel fiber or Modal fibre to make.
The elastic response time of described T400 elastic force long filament is t1; Described t1 >=5 millisecond.
Spandex filament is as the core silk of cladded yarn, in the spinning systems such as RING SPINNING, the slower speed of a motor vehicle and lower drafting force can not have much impact to spandex body, but when entering in air-jet eddy-current spinning spinning process, spandex filament is subject to comparatively violent stretching action in cup, within the time of about 1-5ms, very easily reach the limit of extended state, produce fracture, production efficiency is extremely low.
Described T400 elastic force long filament, possess good flexible while, elastic modelling quantity is higher, and the elastic response time is longer, and do not reach capacity extended state in 1-5ms, can meet the demand of production and processing.
The specification of described T400 elastic force long filament is 1.50D/32F, 2.75D/32F, 3.40D/32F, 4.100D/32F or 5.150D/32F.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
