The quick device for sizing of a kind of yarn
Technical field
The present invention relates to a kind of textile manufacturing equipment, particularly the quick device for sizing of a kind of yarn.
Background technology
Sizing is the critical process of weaving engineering, and the object of sizing mainly forms layer protecting film on yarn, improves the ABRASION RESISTANCE of yarn; reduce filoplume, suitably increase the brute force of yarn, reduce and extend; to bear yarn mechanism ability complicated in weaving process, improve the weavability energy of yarn.Since over half a century, weaving and chemical industry expert concerted effort are share both at home and abroad, adopt multiple method (as adopted heat treatment to chemical fiber yarn, adopt special chemical reagent or lubricant, yam surface is carried out to lubricated etc.) expect to get rid of sizing process to solving due to starching at substantial resource, and dye-printing desizing sewage is to the pollution of environment, to reach the object that economize energy reduces production cost and cleaner production.But due to different yarns, fabric specification, the type of temperature and humidity conditions and loom, the problems such as speed, also fail to realize carrying out alternative traditional method for sizing by more practical method up to now.Equipment at present for warp sizing is made up of four major parts: 1. pedestal: the warp beam of placing defined amount, the warp thread radical of extraction generally equals the total radical of fabric warp.2. stock tank: to store, the container of (insulation) slurries of heating and add-on component.Submergence roller adsorption slurry walked around by warp thread, then through being squeezed between sizing roller and the squeezing roller being surrounded by resilient membrane, slurries penetrated in yarn and pressure removes remaining slurry, reaches the rate of sizing of regulation.3. storehouse is dried: the device of drying wet pulp yarn, is divided into drying cylinder formula, hot air type and hot blast drying cylinder association type three class.4. headstock: comprise the mechanisms such as main transmission, after waxing device, lease rod, survey long dozen print, expansion reed, beam winding, upper doff.Main transmission requires wider range of infinitely variable speeds, and has creep speed (2 ~ 3 ms/min), to adapt to the requirement of disposal without shutting down fault.The sizing of oven dry is divided into some layers by lease rod.Fine and closely woven layer or chemical fibre sizing coat micro-emulsifying wax by after waxing device, make sizing surface smoothing and reduce electrostatic accumulation.Sizing after layering separates further through expansion reed, finally by towing roller around upper beam of a loom.Beam winding mechanism under the different speed of a motor vehicle and beam winding increasing diameter when can make sizing tension keep constant.The survey long dozen of sizing prints to sizing with the mark of coupe, generally carries out after the drying.
There is following defect in this method for sizing: 1, yarn must through submergence roller and squeezing roller compregnate, particularly at popularization " two high one low " (high concentration of slurry, high squeezing pressure, low slurry viscosity) sizing technique environment under, squeezing roller pressure is up to 50kN, now yarn texture there will be obvious destruction, there is slippage in fiber, friction cohesive force after destarch between fiber obviously weakens, simultaneously because slurries immerse yarn interior, follow-up destarch pressure is comparatively large, produces man-made further destroy to yarn texture, finally affects the durability of fabric.2, the drying mode of sizing mainly contains hot air type, drying cylinder formula and hot blast drying cylinder association type three kinds.It is better that hot air type drying forms plasma membrane integrity, but the thermal efficiency is lower; The drying cylinder formula drying thermal efficiency promotes to some extent, but the plasma membrane integrity formed is poor, and oven dry sizing is from the close-by examples to those far off, and the part contacting drying cylinder is exactly dried at first, and the oven dry away from drying cylinder is slower.Hot blast drying cylinder association type drying falls between.This several drying mode causes device for sizing volume comparatively large, consumes energy higher.3, spinning sizing agent has starch, polyvinyl alcohol (PVA) and acrylic size three major types.What mainly use both at home and abroad now remains this three major types slurry.The existing loom of China about about 1,000,000, wherein shuttleless loom accounts for 30%.According to interrelated data report, 2006 produce cloth 437.97 hundred million meters per year, by producing the estimation of cloth amount, consume slurry year more than 300,000 tons.Wherein starch based (comprising converted starch) accounts for more than 70%, PVA consumption less than 20%, and acrylic compounds and other slurry are about about 10%.For this few class slurry, film forming is crisp and hard, particularly starch size, although its good film-forming property, serous coat brute force is high, but serous coat is firmly crisp, degree of stretching is little, and serous coat is easy to come off, poor stability high to hydrophobic fibre (as terylene) poor adhesion, pulping rear slurry viscosity, slurries use viscosity B coefficent comparatively large in a long time, affect sizing quality.Be impregnated in the space between yarn interior fiber and fiber by slurries, the relative adhesion of fiber, increases interfibrous cohesive force, improves the fracture strength of yarn, but the amount expending slurry is comparatively large, and follow-up destarch difficulty, power consumption is large.4, when with pure PVA or the PVA starching with vast scale, after compregnate, sizing often sticks together, if directly carry out drying, after be difficult to be separated, therefore to carry out hygroscopic water strand, often occur when leasing splitting yarn phenomenon, cause sizing hairiness to be greater than raw yarn filoplume.5, the difficult degradation of PVA slurry pole causes environmental pollution, acrylic size price is higher, substitution for PVA is gradually understood in the development of starch derivatives slurry and other appearance that can be used for the slurry of yarn sizing, these slurries have fast filming, high-strength flatness and good water solubility is convenient to the advantages such as recovery, and traditional device for sizing and method have been not suitable for the starching of some novel slurries.6, the sizing after starching is after squeezing roller, slurry major part can be retained in yarn interior, moisture is forced out, therefore, the concentration of the slurries inside former sizing groove diminishes, thus causes the rate of sizing of front and back sizing different, in follow-up weaving process, sizing by force stretching property is variant, affects globality and the quality of final fabric.
