Description
Technical Field
The invention relates to the technical field of detection of the curl elasticity of wool fibers, in particular to a wool curl number measuring ruler.
Background
Wool curling is a process in which wool in its natural state presents regular curling waves along the length direction. Curl is classified into 7 types such as a flat wave, a long wave, a shallow wave, a normal wave, a flat circular wave, a high wave, and a broken line wave according to the difference between the curl waveform and the curl number. The number of curls of the fine wool is generally 4 to 9 per cm. The detection items of the curl performance mainly include the curl number, the curl rate, the curl recovery, the curl elastic recovery, and the like.
The curling of wool has a remarkable correlation with the internal structure and chemical composition of the fibers, and is formed by the bilateral structure of the front and the back cortex of the wool and the periodical movement of hair follicles, which is a good characteristic of wool. The characteristics of the wool are affected by a plurality of factors, different varieties of wool often have different curling forms, when the conditions of sheep raising are different, curling conditions are different, and the curling of the wool growing on different parts of the same sheep is also different.
The crimp performance of wool is a technical index which is important as fineness and length and can express the thickness, quality and processing performance of fiber. Wool crimp performance is twofold, and first, wool crimp is desirable for many products, particularly carpets, and increased crimp generally improves crush resistance and hand feel, and low crimp wool improves carpet performance by increasing artificial crimp, which increases softness, smoothness, and fullness of the product. On the other hand, the curling of wool is sometimes disadvantageous for processing, the curling degree of wool increases, the strength and elongation at break of yarn decrease, the unevenness increases, the nub increases, and particularly, excessive curling degree is disadvantageous for spinning processing and its products. In summary, crimp is also an important character of the fibers, affecting the improvement of the fibers and the quality and style of the textile, such as bulk, compression elasticity, hand, cohesion, and processing properties such as mixing, carding, and drawing of the fibers. The normal wave and shallow wave wool is suitable for spinning high-grade smooth combed wool yarn, and the high wave wool has better fulling property and is suitable for coarse combed wool spinning.
The wool curl measurement internationally adopts detection methods such as a mechanical stretching measurement method, a Sirolian-LaserScan method, an OFDA method and the like, and the methods are required to be detected in a laboratory through large-scale instruments, so that the method is inconvenient to use, and most sheep farms and laboratories are difficult to equip with the instruments. Therefore, the most commonly used method for measuring the curl of wool is also a hand-feeling visual method, and the judgment result of the method is greatly influenced by human factors. The patent designs a measuring ruler for detecting the number of curls of wool, which has the advantages of simple design, convenient use, visual measurement, accurate result, two measuring modes, one simple and one quick; the bending number of the upper, middle and lower three parts of a bundle of wool can be measured simultaneously; the movable pointer is used for indicating the counting area, so that the measurement is accurate and the error reading is not easy.
