Abstract
The invention relates to a yarn processing method. A flake yarn amplitude shrinking padding method is processed according to the following two steps of: the first steps of amplitude shrinking padding: dipping the flake yarn unreeled from a warp beam after shrinking amplitude by an amplitude shrinking roller into a dipping slot, putting the yarn after dipped into a padder to remove redundant dipping liquid; the second step of amplitude expanding rolling; carrying out rolling on the flake yarn out of a roller after amplitude expanding by an amplitude expanding roller. The invention is mainly characterized in that the amplitude shrinking padding of the yarn integrates the advantages of bunchiness padding and flake padding and overcomes the defects of the two. The colorizing uniformity is improved remarkably; the left and right color difference and the front and back color difference are reduced remarkably; wherein, the left and right color difference reaches grade 4.5; the front and back color difference reaches grade 4.0, thus meeting the technical requirements. The device adopted by the invention has simple structure and reduces the broken end rate to a large extent.
Description
Technical field:
The present invention relates to the yarn processing method, particularly yarn pads method, also relates to the yarn width of cloth squeeze device that contracts in addition.
Background technology:
Yarn pads method and is meant that the yarn dipping comprises the various maceration extracts of dye liquor, the method for rolling unnecessary maceration extract then by padding machine.
Existing yarn pads method and can be divided into pencil by the yarn arrays shape and pad with sheet and pad two kinds.So-called pencil pad be with separately independently yarn bundle (every bundle 300-500 one thread) pad, it represents device is the pencil dyeing machine.The advantage that pencil is padded is to pad evenly, and shortcoming is that operation is many, and efficient is low, the dividing sinker difficulty.It is that yarn with being arranged in sheet continuously pads that so-called sheet is padded, and it represents device is sizing-dyeing machine.The advantage that sheet is padded is that operation is few, the efficient height, shortcoming be pad inhomogeneous.
The disclosed application number of the inventor is 200710011197.9 Chinese invention patent application, and it is that sheet is padded that the yarn that is adopted pads method.It all is that constant amplitude is padded at present that the yarn sheet is padded, and fabric width approximated and pads the back fabric width before promptly yarn padded.The weak point that constant amplitude is padded is: 1, sheet yarn limit portion and middle part band liquid measure are inconsistent; 2, constant amplitude is padded and is difficult to dwindle the dipping tank volume, will produce the hydrolysis of reactive dye phenomenon.The reason that produces this deficiency is: during yarn behind the padding machine roll compacting dipping, because sheet yarn fabric width approaches padding machine roll length, influenced by the roll flexible deformation, the roll pressure at two ends is big, intermediate pressure is little, causes sheet yarn limit portion and middle part band liquid measure inconsistent, thereby produces aberration.In order to overcome this not foot phenomenon as much as possible, adopt expensive evenness calender to solve the flexible sex change problem of roll in the prior art.About reactive dyeing, the staining bath volume faces dilemma.Yarn is fully soaked into, and this needs yarn to satisfy certain time of staying in dye liquor, and therefore, the staining bath volume is the bigger the better.But, the time of staying of dye liquor in staining bath usually should be above 10 minutes, otherwise will produce hydrolysis of reactive dye and increase the transitional aberration length of yarn, consider that from this some the staining bath volume is the smaller the better, but little volume staining bath be subjected to the constraint of sheet yarn width and dip time again.Therefore prior art is difficult to solve simultaneously the problem of two mutual contradictions.
Summary of the invention:
The objective of the invention is to solve the deficiencies in the prior art problem, a kind of sheet shaped yarn pinches slop padding method is provided, the width of cloth squeeze device that contracts also is provided in addition.The technical scheme that the present invention is adopted for achieving the above object is: a kind of sheet shaped yarn pinches slop padding method, undertaken by following two step process:
The first step width of cloth that contracts pads: will enter the dipping tank dipping from the sheet yarn through unwinding on the axle after the width of cloth roller that contracts contracts the width of cloth, the yarn behind the dipping enters padding machine roll compacting and removes unnecessary maceration extract;
The second step expanding is reeled: the sheet yarn that goes out roll is reeled behind the spreading roll expanding.
The described yarn width of cloth that contracts pads dip time for being no less than 6 seconds.
Sheet shaped yarn pinches slop padding device of the present invention, mainly formed by contract width of cloth roller, dipping tank, padding machine and spreading roll, unwinding dynamically connects the width of cloth roller that contracts through axle by the sheet yarn, the width of cloth roller that contracts dynamically is connected by the sheet yarn with the dipping tank inlet, dipping tank outlet yarn dynamically connects padding machine, padding machine dynamically connects spreading roll, and spreading roll dynamically connects coiling through axle.
Described contract width of cloth roller and spreading roll are respectively along deflector roll roll surface circumferencial direction and are mounted alternately with big circular slice and sequin, form the groove of yarn operation between two big garden sheets.
The substantive distinguishing features that the present invention gives prominence to is, the yarn width of cloth that contracts pads and has pencil concurrently and pad the advantage of padding with sheet, and has overcome the two shortcoming separately.The employing width of cloth that contracts pads technology and pads, and only takies conventional padding machine roll sub-fraction, and the roll flexible deformation is reduced at double to the influence of quality, thereby to use common padding machine be the evenness calender of alternative costliness.Second outstanding substantive distinguishing features of the present invention be, pads mode guaranteeing successfully to have dwindled the dipping tank volume under the dip time condition by the yarn width of cloth that contracts, and solved the REACTIVE DYES trough inner water and separated problem.Experiment shows, is that 200710011197.9 the sheet yarn constant amplitude that is adopted is padded and compared with disclosed application number, and dye uniformity obviously improves, and side-to-side shading and front and back aberration obviously reduce.Wherein, side-to-side shading reaches 4.5 grades, and the front and back aberration reaches 4 grades, has satisfied specification requirement.The 3rd outstanding substantive distinguishing features of the present invention be, the width of cloth rod that contracts, expanding rod have realized that with the contact point of yarn face contacts, and traditional expansion reed is a contact with contacting of yarn.The former is little to thread wear, has reduced end breakage rate largely.
Apparatus structure of the present invention is simple, and the spreading roll structure is identical with the width of cloth roller that contracts, but effective length is greater than the effective length of the width of cloth roller that contracts.The effect of width of cloth roller of contracting is that wide cut sheet yarn is condensed to sheet yarn in a narrow margin; The effect of spreading roll be the even open-width of yarn after the width of cloth that contracts is padded to the regulation fabric width, carry out follow-up coiling.
