Abstract

The invention discloses a method for reducing twist deterrent effect of a yarn guide hook. A yarn guide hook is provided with a blowing device. The yarn guide hook comprises a spiral hollow channel, and the maximum diameter end of the spiral hollow channel is connected with an air pipe of an air compressor. High-pressure air reaches an air outlet on the middle of the minimum diameter end of the hollow channel through the spiral hollow channel, and the high-pressure air blows out. The air outlet is 0.2 mm above the center axis of the minimum diameter end. Airflow blown out from the air outlet blows yarns which are tightly abutted against the yarn guide hook caused by yarn tension, and reduces pressure between the yarns and the yarn guide hook, so as to reduce friction force between the yarn and the yarn guide hook, reduce twist falling effect, prevent a spinning stage from breaking, and improve yarn quality.

Description

A kind of method that reduces the effect of twizzle resistance twist

Technical field

The present invention relates to spinning new technical field, one can be installed at ring ingot specificallyBlowing device on the twizzle of spinning frame, reduces the sunken method of the sth. made by twisting of twizzle to realize, carriesThereby the high spinning section twist improves spinning section yarn breaking force, is lowered into the band of twist per unit effectThe twizzle of blowing device.

Background technology

All the time, RING SPINNING is because having adaptability to raw material and higher yarn quality widelyAnd gain great popularity. But in RING SPINNING resultant yarn process, yarn need to pass through the parts such as twizzle,Twizzle is a turning point in ring spinning frame spinning process, to the biography of the sliver twistStability, minimizing fuzzy yarn and the broken end of passing, control spinning air ring are all most important. Therefore,In the last few years, be there is to several different methods in the transformation of twizzle. But these transformations are not from rootIn basis, solve this essential problem that falls into of twisting with the fingers. Twist with the fingers sunken referring in twisting area, because sliver existsRun into the friction of parts, the twist on the sliver of Partial Fragment outside twisting point and parts is subtractedFew, this phenomenon that the twist in sliver fragment is reduced due to friction is called to twist with the fingers and falls into. Twist with the fingers and fall intoMainly to produce because there is friction. Cause the twist of spun yarn spinning section owing to twisting with the fingers sunken existenceLower than the air ring section twist, cause spinning section powerful not enough, easily produce broken end.

On spinning frame, claim to spin to the fiber assembly twizzle from front roller output jawYarn section, its ultimate strength is powerful claims spinning powerful, spinning brute force depends on guide to a great extentHook. Therefore, in spinning practice process, to twizzle require comprise have wear-resisting, smooth,And the coefficient of friction between yarn is as far as possible little, fall into effect with the sth. made by twisting that reduces yarn. For this,The present invention provides the method that reduces the effect of twizzle resistance twist, adopts a kind of guide with blowing apparatusHook, this device blows out air-flow by blowing device to the yarn being close on twizzle, makes yarnPressure between surface and twizzle reduces, thereby reduces the friction system between yarn and twizzleNumber, its objective is that the sth. made by twisting that effectively reduces original twizzle falls into effect, improves the twist of spinning section,Thereby improve the brute force of spinning section, reduce the broken end of spinning section, improve yarn quality.

Summary of the invention

The object of the invention is to provide one can be installed on ring throstle to realize reductionThereby the resistance twist of twizzle, the raising spinning section twist improve spinning section yarn breaking force, reductionBecome the twizzle with blowing device of twist per unit effect. For achieving the above object, the present invention adoptsOn ring spinning frame, install a kind of twizzle with blowing device additional and replace original twizzle, yarnLine, after front roller nip is drawn, by the hollow passageway of the twizzle with blowing device, is subject toThe spin friction effect of twizzle, reduces the effect of falling into of twisting with the fingers.

The method that reduces the effect of twizzle resistance twist disclosed by the invention, comprises that spirality is hollow logicalRoad, described hollow passageway outer wall is irony material, bottom surface maximum outside diameter, between 7-8mm, pushes upFace minimum diameter is between 2-3mm, and height is between 12-15mm, and the diameter of hollow passageway is3mm, helix comprises 2-3 circle, described cylinder type hollow passage maximum gauge end and air compressor machineTracheae is connected, and the blowing that pressure-air arrives hollow passageway minimum diameter end by hollow passageway goes outMouth blows out, and described blowing outlet is at the center line side 0.2mm on the upper side of minimum diameter end, from blowingThe air-flow that outlet blows out blows because yarn tension causes being close to yarn on twizzle, thereby subtractsFrictional force between little yarn and twizzle, thus reduce to twist with the fingers sunken effect, improve spinningThe twist of section, has reduced the broken end of spinning section.

In described air compressor machine tracheae, air pressure can, according to the adjusting that needs of production technology, further be adjustedPressure between joint yarn and twizzle. Said structure can be realized with same air pressure drive allTwizzle, realizes the technological parameter uniformity in spun yarn spinning process.

The novel beneficial effect of the present invention is: by adopting a kind of spiral line type band blowing deviceTwizzle, and air pressure in the tracheae connecting by adjusting blowing device, regulate yarn and guidePressure between hook, thereby regulating friction force, the sth. made by twisting that can obviously reduce original existing twizzle falls intoEffect, the twist of raising spinning section, reduces spinning section broken end, improves yarn quality.

Brief description of the drawings

Fig. 1 is the structural representation of the twizzle with blowing device.

Detailed description of the invention

The method detailed description of the invention is further elaborated, by reference to the accompanying drawings shown in.

As shown in Figure 1, reducing the band blowing device that the method for twizzle resistance twist effect adopts leadsYarn hook, comprises spirality hollow passageway 1, and spirality hollow passageway 1 outer wall is irony material,Maximum outside diameter is between 7-8mm, and end face minimum diameter is between 2-3mm, and height is at 12-15mmBetween, the diameter of hollow passageway is 3mm, helix comprises 2-3 circle, described cylinder type hollowPassage maximum gauge end A is connected with air compressor machine tracheae 2, and pressure-air arrives by hollow passagewayThe blowing outlet 3 of hollow passageway minimum diameter end B, the air-flow blowing out from blowing outlet blow byCause being close to yarn 4 on twizzle in yarn tension. When installation by twizzle maximum gauge endA is inserted into original leaf plate hole inside.

In use procedure, the air pressure in hollow passageway 1 can be according to the demand adjustment of production technologyAir pressure regulator 5, the larger yarn of yarn tension is more close on the inwall of hollow passageway 1, thisTime can increase air pressure, reduce twizzle sth. made by twisting fall into effect, complete spinning process. It calculates publicFormula is defined as: resistance twist barometric coefficient R:

$R=\frac{P}{T}$

Wherein: P is pressure (N/m²), T is yarn tension (N).
