Abstract
The scheme of the invention is a single-plate directly-spun technology for fine denier polyester. Common melt-spun fine denier fiber is made by combining two spinneret plates. The technology is characterized in that: it adopts a spinneret plate filature and a melt body directly-spun technology and an EVO external cross air-blow technology for cooling with the wind velocity of about 0.5 plus or minus 1m/s and dpf ranges between 0.38 and 0.52 as well as perfect dyeing performance, which is different from mixed fabric; the mixed fabric technology needs further processes that might both pollute environment and influence dyeing effects if the further process is not done well,.
Description
Technical field
The present invention relates to a kind of production technology of macromolecular fibre, especially a kind of fine-denier polyester veneer direct spinning technology.
Background technology
Present super fine polyester technology as monfil 0.55dtex≤dpf, generally adopts direct spinning production, and common has: polyester DTY 150D/288F, polyester DTY 65D/204F etc.; As monfil 0.33dtex≤dpf≤0.55dtex, generally adopt compound sliver to peel off method production, common has: terylene meets a DTY150D/48F*16P, polyester-cotton blend meets a DTY160D/72P; As monfil 0.11dtex≤dpf≤0.33dtex, generally adopt compound sliver to peel off method or island method liquation production; As monfil 0.001dtex≤dpf≤0.11dtex, generally adopt island method liquation to produce, common has: 75D/36F*371DTY, 160D/60F*371DTY.
Because the demand of super fine polyester product is big, be to adopt compound sliver to peel off method for the fiber popular technique of 0.3～0.5DPF, qualification rate is low like this, and production capacity is restricted, thereby makes the production cost height, can not satisfy the market demand and the release market demand.
Summary of the invention
Task of the present invention is: a kind of fine-denier polyester veneer direct spinning technology is provided.
The technology of the present invention is constructed as follows:
A kind of fine-denier polyester veneer direct spinning technology of the present invention program, the fine count fiber of general melt-spun all adopt two blocks of spinnerets plying to form, and its technical characterictic is to adopt a spinnerets spinning; The fused mass directly spinning technology; The type of cooling adopts EVO outer shroud blowing technology, and wind speed is about 0.5 ± 1m/s; Dpf is between 0.38～0.52.
With respect to original technological progress effect be like this: dyeability is good, unlike compound spin come also want post processing, if contaminated environment not only is the bad Color that also influences of post processing.
The specific embodiment
In specific implementation process, spinnerets can adopt the porous circular arrangement.The rounded distribution of spinneret orifice on the spinnerets, spinneret orifice is made up of guide hole and spray silk pore, the cross sectional shape of 384 or 528 spray silks of its veneer pore is to be formed around central array by a plurality of circular ports, the center of circle of described each circular port is in the outside, plate center and be arranged in circular concentric, cuts off between the described adjacent circular port cross-drilled hole end.Easy to process like this, be convenient to adhesion between each hole wall, make the warmth retention property of fiber and resilience better.
In specific embodiment, can adopt veneer 384,528 hole melt spinning techniques to solve sub-thread 200D/384F, the quality of production of 200D/528F super fine polyester and the problem of speed.
Claims (2)
1. a fine-denier polyester veneer direct spinning technology is characterized in that in the fused mass directly spinning technology, adopts a spinnerets spinning, and dpf is between 0.38～0.52.
2. technology as claimed in claim 1 is characterized in that the type of cooling adopts EVO outer shroud blowing technology, and wind speed is about 0.5 ± 1m/s.
