Description
Technical field
The present invention relates to wool top production technology fields, and in particular to a kind of production technology of terylene bulky top.
Background technique
With the progress and the improvement of people's living standards of modern science and technology, people require to get over for the comfort of garment material
Come higher.Wherein it is desirable to garment materials to have good bulkiness and high resiliency.But existing clothing fabric is due to life
Production. art it is not perfect, cause garment material that can not have good bulkiness and high resiliency simultaneously, to be unable to satisfy people
Requirement.
Summary of the invention
It is used for face weave the technical problems to be solved by the present invention are: one kind will be provided and makes fabric while having good
The production technology for the terylene bulky top that bulkiness and high resiliency require.
To solve the above-mentioned problems, the technical scheme adopted by the invention is as follows: the production technology of terylene bulky top, technique
Steps are as follows: raw material drying → screw extruding spinneret → winding boundling → tow post-processing → tow cuts off item → one of grilling processed
→ bis- grillings → balling-up grilling, it is characterised in that:
(1) in screw extruding spinneret process: carrying out melt extruded spray to the polyester slice raw material after drying in screw extruder
Silk, polyester slice raw material revolving speed be 80~85m/s screw rod promotion under, pass sequentially through first screw extruder an area and
2nd area are preheated, and the temperature in an area is 278~282 DEG C, and the temperature in 2nd area is 283~287 DEG C；Then pass sequentially through 3rd area and
4th area are melted, and the temperature in 3rd area is 288~292 DEG C, and the temperature in 4th area is 288~292 DEG C；Then pass sequentially through 5th area and
Extruding spinneret is carried out being rationed to each spinneret station behind 6th area, and the temperature in 5th area is 283~288 DEG C, the temperature in 6th area
Degree is 278~282 DEG C, the silk that it is 40~43 DEG C to a temperature that each resulting endless tow of spinneret station spinneret, which can be respectively enterd,
Circular blow solidification is carried out in room, circular blow air output is 1200~1300m/s, and circular blow supply air temperature is 38~40 DEG C；
(2) it winds in collecting compacting stage: each resulting endless tow of spinneret station successively being passed through into feeding-wheel and traction roller group carries out
Boundling, thus to obtain sub-thread terylene varicosity tow, when boundling, the speed of traction roller group and feeding-wheel is 800~900n/
