Problems solved by technology

The traditional detection of fiber parallel straightness and separation is mainly done manually. The method is cumbersome and time-consuming. The test results are greatly affected by the subjective, and the information of the response is not accurate enough. Its application is greatly limited.

Embodiment Construction

[0015] 1. Pick the sliver on the carding machine or drawing frame, and take 8-12 layers to make a 100×100 (mm) sample. The thickness of the sample is required to be uniform to avoid light transmission.

[0016] 2. Turn on the power and preheat the instrument for 10 minutes. Use the black tube to adjust zero (Adjust Zero), use the standard whiteboard to adjust white (Standard), and enter the sample (Sample) state under the instruction of the instrument.

[0017] 3. When measuring each cotton web sample, place it on the test bench at a position where the diagonal line of the square cotton web is parallel to the front-to-back direction of the instrument.

[0018] 4. Measure each sample 10 times and read the Hunter.

Abstract

The invention relates to a new method of detecting the inner structure of a cotton silver. The method can substitute traditional tests of fiber extended parallelization and separation degree.

Description

technical field [0001] The invention relates to a new method for detecting the internal structure of cotton sliver, which can replace the traditional testing of fiber straightening parallelism and separation. Background technique [0002] Spinning production is a discontinuous production process, in which raw sliver, semi-cooked sliver, cooked sliver, combed sliver and other semi-finished products will be produced. The quality inspection of semi-finished products can be divided into two aspects: appearance index and internal structure. The appearance index refers to the uniformity of the long and short segments of the sliver and the content of neps and impurities, etc., which belong to the routine inspection content. The internal structure can reflect the internal quality of the sliver, which is generally expressed by the parallel straightness and separation of fibers. The traditional detection of fiber parallel straightness and separation is mainly done manually. The metho...
