Description
Technical field
The present invention relates to a kind of waste silk raw materials recovery processing technologys, and in particular to a kind of waste silk raw material production extra white is high-strength low
Middle long and short fiber technique is stretched, regeneration extra white fibre process technical field is belonged to.
Background technology
In the process of manufacture of polyester fiber fused mass directly spinning, due to lousiness, broken end phenomena such as appearance can lead to one
The generation of fixed number amount waste silk, with the increase of polyester fiber production capacity, the waste silk doses in production process also can accordingly increase；How
Simply and effectively this part waste silk material of reuse, for saving raw material dosage, reduction production cost improves the economic benefit of enterprise,
Suffer from larger realistic meaning；The recycling application method of the polyester waste silks industrially used at present is broadly divided into two kinds；One is
Using the chemical methodes such as alcoholysis or basic hydrolysis degradation polyester waste silks, is recycled through row in the form of monomer, chemically gathered
Process is complicated when ester waste silk reuse, will produce three wastes problem, and product all Shortcomings in economy and quality；The second is will gather
Ester waste silk re-melts extrusion and plastics or low-grade fiber is made, but polyester waste silks can cause to glue during remelted because being pyrolyzed
Degree reduce, therefore using polyester waste silks be raw material re-melt extrusion made from polyester fiber it is second-rate, can only generally be used as cotton for wadding
Or non-woven fabrics；It also lacks a kind of effective method at present, realizes following for waste silk in polyester fiber control system in melt direct spinning production process
Ring utilizes；For this purpose, Chinese Patent Application No.：201210335518.1 disclosing a kind of returning online for fused mass directly spinning oil-free waste silk
With method, the specific steps are：(1) pre-treatment (2) melting (3) viscosifies (4) online reuse, and waste silk melt pipe passes through metering system
Melt conveying pipeline is accessed, the waste silk melt after thickening enters melt conveying pipeline via waste silk melt pipe, in order to ensure to gather
The stability of ester fiber production technology and performance, the flow-rate ratio for controlling waste silk melt and spinning melt is 1: 20 ~ 1: 5；Waste silk is molten
Body is mixed with spinning melt through melt conveying process is full and uniform, continues to participate in the production process of polyester fiber fused mass directly spinning；This
Invention can effectively save raw material dosage by the oil-free waste silk generated during online recycled polyester fused mass directly spinning, real
Waste silk recycles in existing polyester fiber control system in melt direct spinning production process；Waste silk melt is viscosified by the way that chain extender is added,
The problem of waste silk melt be can effectively solve the problem that because molecular weight and viscosity decline, influence spinning technique performance；But it is not improved
The utility value of waste silk, waste silk later stage preparation product quality is not high enough, and can not be carried out at later stage recycling to oily waste silk well
Reason.
