Description

Seluofle spinning modulus compensator

Technical field:

The invention belongs to field of textiles, it relates to a kind of Seluofle spinning modulus compensator.

Background technology:

Nineteen nineties, Australian CSIRO mechanism is spun on the basis at the match network, has invented the Seluofle spinning technology again.As shown in Figure 1, be about to match the rove that network spins and change long filament 1 into, long filament 1 is directly fed by the front roller of draw zone 5 by godet roller 3, tensioner 4, after another root rove 2 process draw zones 5 normal drawing-offs, both are in the front roller nip downstream and close twisting, one step resultant yarn forms cop 8 through twizzle 7 again.The Seluofle yarn is because the introducing of long filament 1, and its yarn property increases again on match doff basis, almost can with compare favourably with the number strand, can realize that yarn exempts from starching and weave.This method has broken through raw material and the machinability two big obstacles that institute must run in high the light and thin fabric exploitation, is one of excellent process of developing by frivolous woolen knitwear.Yet the Seluofle yarn that prior art is produced is in actual weaving process, and short fiber is easy to be pulled out from the yarn body, form " stripping hair " phenomenon, make the upper and lower layer of loom opening part warp thread inter-adhesive, cause opening unclear, loom board efficient reduces, and is difficult to produce continuously.

Summary of the invention:

For overcoming above-mentioned defective, the invention provides a kind of Seluofle spinning modulus compensator, to solve yarn " stripping hair " problem in weaving process, improve loom efficiency.

According to experimental study, " stripping hair " is main relevant in the configuration of yam surface with staple fibre yarn with long filament.On long filament and the uniform yarn section of staple fibre yarn looping, ability is strong for yarn anti-" stripping hair ", and on long filament and the uneven yarn section of staple fibre yarn looping, yarn " stripping hair " phenomenon in weaving process is obvious.

By last analysis, solve " stripping hair " problem, that is to say that how to make long filament and staple fibre yarn looping even, promptly be the ideamonger of Seluofle spinning modulus compensator of the present invention.As shown in Figure 2, when not adding modulus compensation hook 10 and modulus adjusting geosynclinal block 11, if add same torsional moment for long filament and staple fibre yarn, because the difference of long filament and staple fibre yarn modulus, long filament is because modulus is big, and then the helical angle on the unit length is little, be that screw line pitch is big, and staple fibre yarn is just in time opposite, and its helical length is short, and spiral angle is big.In brief, when long filament when yam surface forms a turn, staple fibre yarn has formed several turns, that is the two is inhomogeneous in resultant yarn surface looping, thereby has caused yarn " stripping hair " problem in weaving process.When adding modulus compensation hook 10, because the effect of pullling of hook increases the pulling force that acts on the staple fibre yarn, by formula

$L_P=(P\&CenterDot;r)\left\{\frac{\ln \left(\mathrm{se}{\mathrm{<figure-callout\; id="2"\; label="c"\; filenames="C0211075400092.png"\; state="\{\{state\}\}">c</figure-callout>}}^2{\mathrm{\&theta;}}_s\right)-\mathrm{si}{\mathrm{<figure-callout\; id="2"\; label="n"\; filenames="C0211075400092.png"\; state="\{\{state\}\}">n</figure-callout>}}^2{\mathrm{\&theta;}}_s}{{\mathrm{tg}}^3{\mathrm{\&theta;}}_s\&lsqb;\frac{1}{4}+\frac{9}{4}\mathrm{coc}{\mathrm{\&theta;}}_{\mathrm{<figure-callout\; id="2"\; label="s"\; filenames="C0211075400092.png"\; state="\{\{state\}\}">s</figure-callout>}}^2+3\mathrm{<figure-callout\; id="2"\; label="ct\; g"\; filenames="C0211075400092.png"\; state="\{\{state\}\}">ct</figure-callout>}{g}^{}{}^2{\mathrm{\&theta;}}_s\ln \left(\cos {\mathrm{\&theta;}}_s\right)\&rsqb;}\right\}$

In the following formula, L _P: owing to the yarn moment of torsion that staple fibre yarn stretches and causes, P: the suffered tensile force of yarn, r: yarn radius, θ _s: yarn surface-helix angle (or adding spiral angle).

As can be known, add modulus compensation hook 10 after, suffered pulling force P increases on the staple fibre yarn, the moment of torsion L of staple fibre yarn _PAlso increase, the modulus difference that is equivalent to staple fibre yarn and long filament reduces, and looping is even, stable when making long filament and staple fibre yarn resultant yarn, has avoided the generation of yarn " stripping hair " problem in weaving process effectively.

The effect that modulus is regulated geosynclinal block 11 is a modulus of stablizing long filament and staple fibre yarn, and preventing influences the stable of long filament and staple fibre yarn modulus because of the variation that spinning tension, rove bar are done, thereby causes its difference of modulus each other, brings extra looping irregular.

For this reason, on existing Seluofle spinning equipment, need install additional:

1. the modulus adjustable hook 10, and the increase by moment of torsion is with the modulus difference between compensation long filament and staple fibre yarn.

2. modulus is regulated geosynclinal block 11, to stablize the modulus size of long filament and staple fibre yarn.

The technical scheme of technical solution problem of the present invention is as follows:

A kind of Seluofle spinning modulus compensator is characterized in that it is fixed on the modulus compensation hook 10 on the reel cage 6 and is fixed in modulus on the circular shaft 13 on the car panel 12 at two ends by kink by the upper end to regulate geosynclinal block 11 and form jointly.

Said modulus compensation hook 10, the radius of curvature R of its lower end crotch is 1-3mm, bar portion is L shaped, bar long m in upper end is 40-50mm, and bar long n in middle part is 70-80mm, and angle α is 90 ° between upper end bar and middle part bar, it is made by thick wire or ceramic material, and the thick wire surface can be carried out chromium plating and be handled; Said modulus is regulated geosynclinal block 11, its aperture φ ₁Be 10-15mm, external diameter φ ₂Be 25-35mm, groove is positioned at modulus and regulates geosynclinal block (11) outer surface, and groove width a is 1-2mm, and groove is processed into oval arcuation, and thickness b is 10-20mm, and it is made by steel material.

Compared with prior art, advantage of the present invention is:

1. continuation maintenance Seluofle spinning yarn strength is big, filoplume is few, bar is done advantages such as even.

2. make long filament and staple fibre yarn modulus before spinning is shaped approaching, make long filament and staple fibre yarn looping even, stable, thereby improved Seluofle yarn anti-" stripping hair " performance effectively, make loom efficiency bring up to 60-70% by existing 30-50%.

3. can select the short fiber raw material widely different for use, enlarge the scope of application of raw material with the long filament modulus.

4. product is applicable to hair and the imitation wool product that exploitation is light, thin, refreshing.
