Description
Technical field
The invention belongs to waste textile recovery and reuse technology field, especially blended fabric to separate and recover recycling side
Method.
Background technique
Three kinds are broadly divided into the processing mode of these waste textiles at present: first is that as second-hand garment marketing or donations
To poor group；Second is that regeneration recycling, including physics regeneration recycling and chemical regeneration recycling；It is buried third is that burning.The first and
Second of proportion be not high, mostly the third；In regeneration recycling, both for the homogenous materials product such as pure cotton
Regeneration recycling, it is difficult to realize that the regeneration to blended product is recycled, all be point using the isolated chemical regeneration recycling of dissolution, degradation
It is poor from effect, cost is high, it is difficult to realize industrialization, therefore the recycling of China's waste and old terylene or polyester-cotton textiles mainly uses at present
Physical method prepares the low value-added reconstituted product such as mop, filling cotton；So urgently developing very much, introducing advanced recycling
Technology accelerates high value added utilization technological industrialization process.
Summary of the invention
The purpose of the present invention is to provide a kind of blended fabric to separate and recover reuse method, and blended fabric is separated into can
The homofil for directly applying to production is recycled, and is realized and is recycled to the high added value of blended fabric, this method pair
The separating degree of blended fabric is high, and high added value recovery utilization rate is high, and cost recovery is low.
Above-mentioned purpose of the present invention is achieved through the following technical solutions:
A kind of blended fabric separation and recovery reuse method, comprising the following steps:
(1) colour examining and classification of blended fabric carries out colour examining to blended fabric, then classifies by tone；
(2) the fibrosis processing of blended fabric mixes the dismantling of classified blended fabric at evenly dispersed multicomponent
Fiber；
(3) dispersibility and electric conductivity pre-treatment are carried out to multicomponent composite fibre, improves the dispersion of multicomponent composite fibre
Property and electric conductivity, increase each component fiber conductivity difference；
(4) composite fibre is dispersed into uniformly by the dispersion of multicomponent composite fibre using mechanical oscillation or air flow settlement method
Thin layer；
(5) the Electrostatic Absorption separation of multicomponent composite fibre, the multicomponent composite fibre after pre-treatment and dispersion is set
It in electric field, is acted on using electric field force, ascend to heaven upwards speed separation or far and near point of falls downward deviation is carried out to each component fiber
From.The strong fiber of electric conductivity is bigger by electric field force in multicomponent composite fibre, first changes orientation, the direction of motion and movement speed
Degree realizes ascend to heaven upwards speed separation or the far and near separation of falls downward deviation of each component fiber.
(6) recycle and reuse is handled, and each component fiber being precisely separating is collected into respectively in different recovery rooms, if point
The fiber separated out is natural fiber or regenerated fiber, then without bleaching of fading, directly as coloured spinning fiber raw material, Huo Zhejin
The quick colour fading bleaching of row, compression are packaged, the spinning fiber raw material as white；If the fiber isolated is synthetic fibers,
It is bleached without fading, directly concentrates melting or dissolution, be then granulated, spinning, obtain coloured regenerated fiber.
