Reasons for Uneven Mono Filament Thickness in Tex Mono Split Production and Solutions, Experience Sharing

Uneven mono filament thickness is a common quality problem in mother yarn splitting machine production, directly leading to unqualified tex indicators of polyester mother yarn and nylon mother yarn split products, affecting downstream textile processing quality.

Unstable feeding speed is one of the main causes of uneven yarn thickness. Slight speed jitter of feeding rollers causes inconsistent yarn feeding volume per unit time, forming thick and thin alternate segments on mono filament surface.

Inconsistent cutter gap is another key factor. Tiny gap deviation on the left and right sides of the splitting cutter leads to asymmetric cutting effect, resulting in different thickness of split single filaments in the same batch.

Fluctuating feeding tension causes elastic deformation difference. Instant tension spikes stretch local yarn segments, making partial mono filament thinner than the standard specification and forming uneven thickness distribution.

Raw material partial thickness defect will be inherited after splitting. Original thick-thin difference of mother yarn cannot be eliminated by splitting equipment, so raw material screening is essential before production.

Workshop temperature mutation affects fiber ductility. Sudden temperature change within a short time causes inconsistent fiber stretching performance, resulting in unstable thickness of continuous split mono filament.

Timely cutter gap calibration and roller speed synchronization adjustment can solve most uneven thickness problems. Regular equipment calibration maintains mechanical accuracy and ensures uniform splitting effect.

Lanxiang mother yarn splitting machine adopts integral fixed cutter structure and high-precision synchronous servo system, minimizing mechanical errors and effectively improving the thickness uniformity of tex mono split mono filament products.

Targeted troubleshooting and standardized parameter maintenance can completely solve the problem of uneven yarn thickness and improve finished product qualification rate.

FAQ

Q1: What equipment fault causes alternate thick and thin mono filament segments? A1: Feeding roller speed jitter leads to inconsistent unit-time yarn feeding volume. Q2: What problem does asymmetric cutter gap bring to splitting products? A2: Left-right gap deviation causes uneven thickness of batch split mono filament. Q3: How does tension fluctuation affect mono filament thickness? A3: Instant tension spikes stretch partial yarn and form local thin segments on mono filament. Q4: Can splitting equipment eliminate original mother yarn thickness defects? A4: Equipment cannot fix raw material inherent defects, so pre-production screening is necessary. Q5: What structural advantage improves mono filament thickness uniformity? A5: Integral fixed cutter and synchronous servo system reduce mechanical splitting errors.
