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, reduce friction, will give yarn sizing.
In recent years, along with the continuous variation 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 better to adapt to market, meet client's demand, except normally producing 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, the production of air-jet loom to DTY long filament kind.In the time short fiber Sizing machines, air-jet loom being improved to production DTY long filament kind, usually that machinery itself is done to large rectification, cause short fiber Sizing machines nondescript, can not produce the good long filament kind of effect, short fiber sizing performance originally is also declined greatly.Finally cause two kinds all can not normally produce.
HS30 short fiber Sizing machines and HS40 short fiber Sizing machines are the short fiber Sizing machiness of two kinds of models of Japanese Tsudakoma Corp production.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 being to provide can reach is only suitable for the rapid draing of short fiber product.So long filament, after starching, utilizes the drying cylinder of short fiber Sizing machines to be dried in the time utilizing HS30/40 short fiber Sizing machines carrying out DTY long filament variety production.Subsequent production cannot be carried out.
Inventor finds that in research process the slurry silk that utilizes short fiber Sizing machines to produce DTY long filament kind is difficult below mainly existing:
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 baking oven equipment, cause cannot drying preferably long filament in long filament is produced.Long filament is dried preferably at jitty, and the most succinct way improves the temperature of drying cylinder.But it is larger to equipment investment that repacking heat is dried wind baking oven, affects short fiber sizing and normally work, raise and accelerate to be dried by temperature merely, not only can make long filament play static, can also strengthen long filament fragility, affect product quality.
2, long filament slurry in the time drying cylinder stainless steel drying cylinder through HS30/40 short fiber sizing owner can adhere to drying cylinder surface, causes adhesion, broken string, the serous coat of long filament to tear damage, the phenomenons such as long filament fluffing.Changing antiseized drying cylinder does not have existing coupling model, and design-build investment is larger, 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 assurance of wax pan oils to long filament abundance, convergence and the flatness of the long filament of impact 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, long filament does not complete pendulum reed in the expansion reed after slurry outlet groove, easily cause long filament after short fiber Sizing machines slurry outlet groove, to occur strand head, glue also, cause making in dry leasing district even broken end of long filament fluffing, affect beam of a loom quality and loom efficiency and fabric quality.So cannot directly utilize at present HS30/40 short fiber Sizing machines to carry out DTY long filament variety production.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, provide a kind of equipment to change little, simple to operate, efficiency is high a kind of slurry silk technique of 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, 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 after by creel unwrapping wire, solid content is housed at 4.5 ~ 5.5% long filament slurry in stock tank, in long filament slurry, is evenly mixed with antistatic additive by the amount of long filament 2 ~ 3.5Kg/ myriametre;
2) long filament after starching draws to the wax pan of short fiber Sizing machines and oils, and fills oil for long filament in wax pan, and long filament adds antistatic additive by the amount of long filament 0.4 ~ 0.6Kg/ myriametre in oily;
3) long filament is dried through drying cylinder after oiling, and the temperature of drying cylinder remains on 150 ~ 155 ℃, and drying cylinder is covered with Teflon adherent layer outward;
4) long filament after drying draw to the dry bursting device of short fiber Sizing machines by the long filament being sticked together separately, long filament separately evenly swings in the expansion reed of machine head of sizing machines position, every warp beam long filament radical is controlled at 680 ~ 760/axle, and by dent of the every threads of axle, after pendulum reed, batch and get final product at machine head of sizing machines.
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 stock tank of short fiber Sizing machines itself, the starching of wax pan, the ability that oils, the control of short fiber sizing locomotive speed is to guarantee that long filament is in the normal key of producing of short fiber Sizing machines.
Preferably, described in step 1), adjusting short fiber sizing locomotive speed is 23 ~ 25m/min.
In step 1), evenly sneak into antistatic additive by the amount of long filament 3Kg/ myriametre.
In step 2, sneak into antistatic additive by the amount of long filament 0.5Kg/ myriametre.Adding of antistatic additive prevents that long filament from producing static after the hyperthermia drying of follow-up drying cylinder at dry bursting device place effectively, reduces long filament fluffing, effectively reduces broken end, increases production efficiency.
