Description
Technical field
What the present invention relates to is a kind of fusion direct spinning superfine denier spandex fibre production equipment of direct melt filtration, belongs to the spandex fibre production technical field.
Background technology
Spandex formal name used at school < POLYUTETHANE>fiber is a kind of spandex of development in recent years, is also referred to as: Si Pandesi < SPANDEX>fiber, PTMG account for 80% (quality molecules) of final polymer, are described as people's " second skin ".It has high flexibility, can elongate 6～7 times, but can return to original state rapidly with the disappearance of tension force, and its molecular structure is picture polyurethanes chain, softness and extensibility, strengthens its characteristic through linking together with hard segment.Generally adopt both at home and abroad at present: chemical method spins, wet method is spun, dry method is spun; More than these three kinds of spinning process all can produce environmental pollution aborning; Complex process, energy consumption is big, floor space is many, investment is big, cost is high; And the elasticity spandex fibre silk of producing contains harmful material. known manufacturing thermoplasticity elastic spandex fiber, fusion slice spinning etc.; Because its producing cost of the elastomer that the fusion slice spinning obtains is high, energy resource consumption is big, and heat resistance, hot water resistance, elastic recovery etc. are all unsatisfactory.Fusion is directly spun then can overcome above shortcoming.The specification of present spandex fibre on the market has super fine denier series (more than the 5D, below the 20D) and conventional serial (more than the 20D); And because the limitation of fusion direct spinning technology; And the super fine denier spandex fibre is higher to specification requirement; The product that has only conventional series at present is so fusion direct spinning superfine denier series is a breach always.
Summary of the invention
The objective of the invention is to have only routine (more than 20 dawn) fusion directly to spin the situation of spandex fibre at present on the market; A kind of fusion direct spinning superfine denier spandex fibre production equipment of direct melt filtration is proposed; Produce the ultra-fine denier polyurethane spandex fibre silk of 5.6D-10.5D; Its spandex fibre is soft, comfortable more, is suitable for using.
Technical solution of the present invention: it is characterized in that first jar of purifying is provided with the first reinforced valve, second jar of purifying and is provided with the second reinforced valve, the 3rd jar of purifying and is provided with the 3rd reinforced valve; Wherein the efferent duct of the first purification jar connects the input pipe of first retort; The efferent duct of the second purification jar connects the input pipe of second retort; The efferent duct of the 3rd purification jar connects the input pipe of the 3rd retort; The efferent duct of first retort joins through heat first input pipe of blender of first metering conveying pump and agitated reactor; The efferent duct of second retort joins through heat second input pipe of blender of second metering conveying pump and agitated reactor; The efferent duct of the 3rd retort joins through heat the 3rd input pipe of blender of the 3rd metering delivery pump and agitated reactor, and the heat efferent duct of blender of agitated reactor directly is connected in series with the input pipe of fondant filter; The input pipe of the efferent duct of fondant filter and the 4th metering conveying pump joins; Additive tank is provided with nitrogen valve, and the efferent duct of additive tank joins through the efferent duct of the 4th metering conveying pump and the input pipe of the 5th metering conveying pump; The efferent duct of the input pipe of manifold and the 5th metering conveying pump joins; The efferent duct of manifold and assembly filter screen spinnerets join; The assembly filter screen spinnerets cooling system of giving a dinner for a visitor from afar, the air channel cooling system with oil device, the first godet roller seal wire stretching device, the second godet roller seal wire stretching device, up-coiler coiling and molding device serial connection.
Advantage of the present invention: the present invention has inherited the advantage of the spandex production of the straight spinning fire resistant special type elastic of fusion, and stability, heat resistance, hot water resistance, elastic recovery, percentage elongation and uniformity all improve a lot.On this basis, it has had some advantages of superfine fibre equally, and the super fine denier spandex fibre is because diameter is very little, so its bending stiffness is very little, the handle of fibre particularly soft; Fiber surface area is very big; Therefore spreadability, bulkiness and the warmth retention property of its fabric are significantly improved, and the number of times that the big fiber of specific area contacts with dust or greasy dirt is more, and greasy dirt; More from the chance of slit infiltration between fiber surface, therefore have extremely strong cleaning function; Superfine fibre is processed the close fabric of superelevation, and interfibrous space is between drop diameter and water vapour diameter of droplets, and therefore ultra-fine fabric has the water-proof air-permeable effect; Superfine fibre has many fine holes between microfiber, form the capillary structure, can then be had high-hydroscopicity by the towel kind fabric of water-wet if be processed into, and this towel of the Hair grooming of washing can sop up moisture content very soon, and hair is done soon.Because their good characteristic is widely used in various fields.
