Description

Be used to improve the method for twisted filament or irregular continuous gauze and the package of this yarn

The present invention relates to a kind of twisted filament or other irregular and incomplete methods of gauze continuously improved.

The invention still further relates to a kind of package of this yarn of improvement.

It is to make yarn have intensity that silk is twisted with the fingers, and has well-balanced outward appearance and relies on the additional a kind of well-known operations technology of giving the various gloss of yarn of twisting with the fingers.

This operation is to be undertaken by giving the certain twist of yarn.Be called on the twisting mill of double twisting and can providing high twist for the form of gauze economy with a kind of densification, in fact, the productivity ratio that processes the desirable twist on a twisting mill is equal to two traditional single twisting mills.

The debatching from the flanged reel of the yarn of delivering to machine has a cap that is made of the element that comprises a yarn seat at the top of this reel, and by means of rotatablely moving of the yarn in the unwinding, this reel gets off yarn unwinding from its bobbin.The process of back yarn from reel, yarn is at first by said seat, this seat can be sleeve pipe for example, hook or other can be finished identical holding and the element of guide function, contact with a tensioner then, then yarn passes through the passage that passes through whole reel on the center of a longitudinal extension, and exposes in the bottom of reel opposite end.Known as a kind of spindle of its overall structure.After leaving central passage by reel, yarn turns back to the outside of spindle and is wound up into again on the element that is positioned at the spindle top.

In rotatablely moving at a high speed, yarn is subjected to the restraining force of two tracks (for example several air ring) in the space.These be referred to as air ring one of them be from moment of reel back yarn point with tensioner (interior air ring) between formation, simultaneously because high speed rotary motion, make that second circle is bigger than first lap width owing to act on action of centrifugal force on the yarn, yarn is in the base point of reel outlet and upholding between the gathering element on the spindle.

Present widely used arrangement mode has some noticeable shortcomings.

These shortcomings come from the shape defect of system and based on the character of yarn in the process.In this respect, problem is a yarn defectiveness and be irregular, and this just means the cross section that some different-diameters or thickness are arranged, promptly often and some inappropriate actual knot, fine hair or piles occur.These irregularities cause debatching to be hindered because stop up yarn, and in the debatching process, the result of this obstruction makes to rotate and produces effect of dragging, and the thing followed is the overlapping of yarn and broken end.Because the operation backward of the twisting from air ring to the feeding reel also produces some problems, operation at this moment will overcome the obstacle that is made of various contact point between yarn and tensioner.This result of operation backward disturbs to cause to rotate by generation to yarn to be piled up and to produce in succession broken yarn.

In addition, the existence of debatching cap obviously complicates the issue, and also must adopt it, solves the access issues from spool, to limit broken yarn during twisting.

During spindle passed, the operator must finish some additional operation, for example, made yarn twine it by the sleeve pipe on the cap or around wheel, to stop the operation backward of sth. made by twisting.

The purpose of this invention is to provide a kind of suitable twisting method to avoid above-mentioned variety of issue.

This purpose is by twisting with the fingers processing, at least pass through double twisting, to irregular and incomplete continuous gauze, the natural silk method of twisting for example, can be fully accomplished, wherein make said yarn after debatching from the tubular support element of the longitudinal axis that has elongation, be subjected to twisting with the fingers processing in succession, on supporting member, yarn is twining on supporting member along a three-dimensional spiral line that extends along said y direction, it is characterized in that, on the every bit of screw line, the tangent line at this some place and this tangent line one perpendicular to the angle between the projection line on the plane of the said longitudinal axis in 3 °～30 ° absolute value scopes.

Advantageously, according to method of the present invention, the package that being used to of irregular and incomplete continuous gauze (for example natural silk) twisted operation comprises having the tubular supporting member that extends the longitudinal axis, yarn is twining along a three-dimensional spiral line that extends on described y direction on it, it is characterized in that, on the every bit of screw line, the tangent line at this some place and this tangent line one perpendicular to the angle between the projection line on the plane of the said longitudinal axis in 3 °～30 ° absolute value scopes.

Other advantages of the present invention and feature will be described in detail in conjunction with several accompanying drawings in the explanation of back by the example of indefiniteness.

Fig. 1 is the side view according to a spindle that method adopted of prior art;

Fig. 2 is the side view according to the employed spindle of method of the present invention;

Fig. 3,4,5 and 6 is schematic diagrames of the employed four kinds of packages of the method according to this invention.

Fig. 1 shows a spindle 10 that is adopted in the twisting method relevant with prior art.It comprises a flanged reel 11, yarn 22 according to traditional approach very closely and in fact almost perpendicular to spool shaft on reel.A kind of unshowned known way of reel 11 usefulness is under static state supporting, and is housed in inside, and partly from than stretching the much bigger hydrostatic column 15 of its diameter.The bottom of container 15 extends into base 13, and this container is rotated by the axle 12 that a usefulness belt 14 is driving, and promptly obtains its motion by this belt.

There is an annular element 16 with holes the top of above-mentioned reel 11, is referred to as cap, and yarn-guiding loop 17 is fixed on this cap.Cap 16 extends upward with the form of a hollow tensioner 18, and a sleeve pipe 19 is arranged on the top of this tensioner.

Base 13 also has a hole 21 that is connected to container 15 inside, the outlet horizontal aligument of this hole and hollow passageway by reel 11.The process of unwinding from reel 11, yarn 22,23 carries out debatching by yarn-guiding loop 17 and around the outside of cap 16, enters tensioner 18 by sleeve pipe 19 then.For yarn 22,23, part 19 has a special gabarit that imports, so that it reduces to minimum to the friction of yarn between the moving period of rotating the hollow interior that moves forward into tensioner.

Device in tensioner 18 inside is not shown, and these devices are used to prevent that turn that the downstream of pipe box 19 applies from returning backward and cross described insertion point, because this situation can upset from reel 11 yarn 22,23 of backing off.

Because yarn has passed emptying aperture part in reel whole, by said hole 21, this yarn just is exposed on the outside, with the retainer ring 20 by being settled on the spindle 10 better.Two parts outside spindle, yarn 22,23 is round the central shaft rotation of reel 11, because action of centrifugal force particularly forms an air ring along part 23, the dot spacing that yarn stretches is wide more, then air ring is big more.In the illustrated case, two said points are respectively hole 21 and ring 20.

Fig. 2 shows a spindle 30 that adopts according to the inventive method.Spindle 30 comprises the several elements identical with common spindle 10, here indicates with identical reference number.In scheme of the present invention, give yarn package 11 ' on twining yarn 22,23, a winding angle is promptly arranged, this angle with respect to package 11 ' the longitudinal axis absolute value angle that becomes a horizontal plane to become 3 to 30 ℃, this angle can make each circle of single yarn reel to keep that good interval is arranged each other, cause on the intersection circle in an opposite direction, become overlapping circle and unlikely generation wrapping phenomena between the yarn, and this wrapping phenomena is just as incidental situation in traditional winding method.

These two features make that yarn package 11 ' upward yarn 22,23 being resigned from office is easy to, and so just can save the cap 16 on the spindle 10 and on the yarn-guiding loop 17 from giving.As the effect of this cap is to keep the axle of certain point and this package on the yarn that enough intervals are arranged so that the unwinding, the unwinding of yarn is constituted a kind ofly significantly radially hinder.It is higher that sleeve pipe 19 is mentioned.This puts on the bigger width of yarn air ring externally, and can allow the qualification aspect of maximal rate to show immediately to the yarn debatching subsequently.

According to the used method of the present invention, wherein give the yarn package radially and height dimension all limited, maximum can allow to twist with the fingers speed and can be improved significantly, up to the twice of conventional speed.

In addition, owing to do not need to use cap, this set to be convenient to and simplified this operation that yarn passes spindle, make the people can faster and easier operation.

Fig. 3,4,5 and 6 show spendable different packages in according to method of the present invention.In these packages, yarn different shape but twining on the always tubular basically supporting member, and shape is at an angle, this angle is to be 3～30 ° of angles in the absolute value scope with respect to become horizontal plane with the longitudinal axis of each supporting member.Especially, Fig. 3 shows a kind of package of flanged pin bobbin shape, and Fig. 4 shows a kind of package with so-called cop of two end topers, and Fig. 5 shows a kind of doleiform package that last end toper is only arranged, and last Fig. 6 shows a kind of Frusto-conical package.

The package of used in the methods of the invention above-mentioned shape or rather, is used to twine these tubular supporting members of yarn, should not be regarded as limitation of the present invention.
