The specific embodiment
The fabric that the present invention knits is non-twist cloth, is to do warp thread with zero twisted yarn, must carry out starching processing to zero twisted yarn.Zero twisted yarn is to adopt conventional yarn and water-soluble fibre yarn reverse-winding untwisting method to produce, and warp sizing method of the present invention comprises:
(1) on bake oven type c Sizing machines, during sizing, must carry out part transformation to equipment, increase and prevent steam-condensation measure, prevent that condensing drip from dropping on yarn face, quality of steam be had relatively high expectations simultaneously, use superheated steam.Effect is poor.
(2) on slasher cylinder machine during sizing, best results.Adopt " low sticky, low temperature, low speed, wet district low-tension " technique.
Low sticky: i.e. slurries low viscosity.Because zero twisted yarn is the folded yarn of conventional yarn and water-soluble fibre yarn in weaving process, not high to sizing index request, more than warp yarn density km grammes per square metre 60g, the thick heavy weave of the rate of sizing 0～7%(can not starching); High-count and high-density fabric, the rate of sizing 5～12%. can meet requirements of weaving process.Therefore, slurries can be selected low viscosity, are conducive to save slurry.According to thickness of yarn degree slurry viscosity from coarse to fine, in 5～6.5 seconds (current are in the time of 4.5 seconds) scopes, select, 6.5 seconds above can do inadvisable, unfavorable to saving slurry because of it.
Low temperature: slurry temperature is lower than conventional sizing temperature is specifically depending on the solution temperature of water-soluble fibre yarn, generally low 5 ℃-50 ℃ than the demarcation solution temperature of water-soluble fibre yarn;
80 ℃～120 ℃ of drying tube temperatures are more low better under the prerequisite that guarantees warp thread oven dry.While just having entered drying because of sizing, yarn body moisture content is more simultaneously, and preliminary drying temperature is lower than rear baking temperature, with 80 ℃～100 ℃, is advisable.Regain should be controlled in 4.5%～8.5% scope.
Low speed: the object of low speed is that assurance warp thread can be dried.Different according to thickness of yarn, the sizing speed of a motor vehicle should be selected in the scope of 30～100m/min, and regain should be controlled in 4.5%～8.5% scope.On bake oven type c Sizing machines, during sizing, because its dry efficiency is low, sizing speed should be controlled within the scope of 25～60m/min.
Wet district low-tension: yarn enters after stock tank little to entering first tension force between drying cylinder.Because water-soluble fibre yarn enters after stock tank, under the effect of slurry temperature, melt and dissolved contraction to a certain degree can occur, heavy produce vitrification phenomenon, overtension can produce unexpected elongation, is even pulled off.General tension force will be controlled at than having twist yarn low 5%～35% to be advisable with propping up.
Zero twisted yarn during because of starching is twine, be to save slurry, and the rate of sizing can on the low sidely be grasped, wherein, sizing more than warp yarn density km grammes per square metre 60g, the rate of sizing is 0～7%, thick heavy weave can not starching; High-count and high-density fabric, the rate of sizing is 5～12%.
The conventional yarn that described making zero twisted yarn is used is the pure spinning of natural fabric or the blended yarns such as cotton, hair, fiber crops, kapok, or the pure spinning of chemical fibre or the blended yarn such as terylene, polyamide fibre, acrylic fibers, viscose glue, bamboo pulp fiber, zein fiber, soybean fiber, model, day silk; The water-soluble fibre yarn that described making zero twisted yarn is used is preferably water soluble vinylon, alginate fibre or carboxymethyl cellulose fiber.
In addition, squeezing roller pressure configuration also should from have twist yarn starching different, heavy after first light, or directly single pressure is singly soaked in employing, focuses on coating.
Above-mentioned method for sizing provided by the present invention and technique, ideally solved the sizing of zero twisted yarn, and energy-saving and cost-reducing, can steam saving more than 20%, and reduce slurry and consume 30%～50%.
It is example with the zero twisted yarn that Quality Pure Cotton Yarn Production and water soluble vinylon yarn (93 ℃ of water solution temperatures) are made that this programme be take on SHGA215C itemize sizing warper whole slurry, and the starching practical art of zero twisted yarn is described:
Formula of size: acetate starch 100%
