Background technology
In textile technology, after fiber spun yarn, intensity is lower, filoplume is more, can not meet woven requirement.In order to improve intensity, minimizing filoplume, the reduction yam surface frictional force of yarn, reducing friction, will yarn sizing be given.
In recent years, along with the continuous change in weaving market, the special kinds such as new varieties, new material, new technology emerge in an endless stream, DTY(draw textured yarn (DTY)) long silk jacquard pattern, small jacquard fabric also enjoy client to favor, each textile enterprise is in order to better adapt to market, meet the demand of client, except can normally produce except DTY long filament kind on the special equipments such as long filament slurry silk machine, water jet looms, also wish to utilize the improvement to equipment, technology, realize short fiber Sizing machines, air-jet loom to the production of DTY long filament kind.When carrying out improvement production DTY long filament kind to short fiber Sizing machines, air-jet loom, usually that machinery itself is done large rectification, cause short fiber Sizing machines nondescript, the good long filament kind of effect can not be produced, short fiber sizing performance originally is also declined greatly.Two kinds are finally caused all can not normally to produce.
HS30 short fiber Sizing machines and HS40 short fiber Sizing machines are the short fiber Sizing machiness of the two profiles number that Japanese Tsudakoma Corp produces.Be adapted to the yarn variety starching of short fiber 83.3tex ~ 5.83tex.Its drying cylinder position is connected with jet chimney, but the drying tube temperature that the steam pressure be to provide can reach is only suitable for the rapid draing of short fiber product.So, after starching, utilize the drying cylinder of short fiber Sizing machines cannot be dry utilizing HS30/40 short fiber Sizing machines long filament when carrying out DTY long filament variety production.Subsequent production cannot be carried out.
Inventor finds that in research process the slurry silk utilizing short fiber Sizing machines to produce DTY long filament kind mainly exists following difficulty:
1, because short fiber Sizing machines is short than long filament slurry silk machine yarn-guiding duct, do not have again heat to dry wind oven equipment, cause to dry preferably long filament in long filament is produced.Dried preferably at jitty by long filament, namely the most succinct way improves the temperature of drying cylinder.But it is comparatively large to equipment investment that repacking heat dries wind baking oven, affects short fiber sizing and normally work, accelerate dry by temperature rising merely, long filament not only can be made to play electrostatic, long filament fragility can also be strengthened, affect product quality.
2, long filament can adhere to drying cylinder surface drying cylinder stainless steel drying cylinder slurry through HS30/40 short fiber sizing owner, causes the adhesion of long filament, broken string, serous coat to tear damage, the phenomenons such as long filament fluffing.Change antiseized drying cylinder and do not have existing coupling model, design-build investment is comparatively large, and down time is long, affects production efficiency.
3, the after waxing wax pan of this short fiber Sizing machines is short fiber after waxing design, and less than normal can not the guarantee of wax pan oils to long filament abundance, affects convergence and the flatness of the long filament after drying cylinder is dried.
4, this short fiber Sizing machines itself does not design the expansion reed after long filament slurry silk machine slurry outlet groove, on the headstock of its flexible button design after dry bursting device, pendulum reed is completed in the expansion reed of long filament not after slurry outlet groove, long filament is easily caused after short fiber Sizing machines slurry outlet groove, to occur strand head, glue also, cause making in dry leasing district long filament to fluff even to break end, affect beam of a loom quality and loom efficiency and fabric quality.So cannot directly utilize HS30/40 short fiber Sizing machines to carry out DTY long filament variety production at present.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, provides a kind of equipment to change little, simple to operate, that efficiency is high a kind of slurry silk technique utilizing short fiber Sizing machines to produce DTY long filament kind.
The technical solution adopted for the present invention to solve the technical problems is: this utilizes short fiber Sizing machines to produce the slurry silk technique of DTY long filament kind, and it is characterized in that, concrete technology step is:
1) adjust short fiber sizing locomotive speed to 20 ~ 25m/min, long filament enters size box sizing by after creel unwrapping wire, and stock tank at the long filament slurry of 4.5 ~ 5.5%, by the amount of long filament 2 ~ 3.5Kg/ myriametre is evenly mixed with antistatic additive in long filament slurry built with solid content;
2) the long filament traction after starching oils to the wax pan of short fiber Sizing machines, fills long filament oil in wax pan, adds antistatic additive in long filament oil by the amount of long filament 0.4 ~ 0.6Kg/ myriametre;
3) long filament is dried through drying cylinder after oiling, and the temperature of drying cylinder remains on 150 ~ 155 DEG C, is covered with Teflon adherent layer outside drying cylinder;
4) long filament be sticked together separates to the dry bursting device of short fiber Sizing machines by the long filament traction after drying, long filament separately evenly swings in the expansion reed of machine head of sizing machines position, every warp beam long filament radical controls at 680 ~ 760/axle, and by axle every threads dent, batch at machine head of sizing machines and get final product after pendulum reed.
First the present invention reduces short fiber sizing locomotive speed more than 50%, to adapt to the production of long filament, for long filament provides suitable pulling speed, coordinate the starching of the stock tank of short fiber Sizing machines itself, wax pan, oil ability, the control of short fiber sizing locomotive speed is the key ensureing that long filament is normally produced at short fiber Sizing machines.
Preferably, adjusting short fiber sizing locomotive speed described in step 1) is 23 ~ 25m/min.
