Experience In Cotton Fiber Inspection

Some details analysis

1. micron value is an important index of cotton fiber. It is a comprehensive measure of maturity and fineness. The fineness of cotton fiber is determined by varieties, and maturity is measured by the thickening of cell wall, so that the micron value of mature fiber is higher, and the fiber with poor maturity can also make the fiber become finer. Its micron value is also lower. Due to the small cavity in the mature fiber, the deformation of the fiber is small when compressed, and the hand feels rough. Its micron value is also larger. Only the cotton with moderate micron value, its fiber maturity is relatively normal, and its utilization value in textile mill is higher.

　　2.棉纤维的光泽：棉纤维的光泽与成熟度，手感弹性之间有着密切的关系，棉纤维系半透明体物质，其光泽直接反映它本身的内部结构和外观形态，又是其成熟度的具体体现，它又与纤维的手感性质直接相关，棉纤维的内部结构从微观结构来说，它不是单晶体，而是由大量微晶体和无定形区所组成，它们的取向一般平行于纤维轴线，纤维的取向度高，纤维的分子排列整齐，透明度就高，纤维的反光性就强，纤维的光泽就好，纤维的成熟度就好，由于棉纤维是大量的微晶体和无定形区所组成，再加上空心形态，所以决定了它本身具有半透明和半弹性的良好性质，由于棉纤维的成熟过程是随着纤维素淀积细胞壁加厚而完成的，所以正常成熟的棉纤维它的光泽是由差到好又变成较差的，纤维的手感也是由塑软性变柔软性，变柔滑性，变成弹柔性最后形成粗刚性。

3. the quality of the cotton fiber has a great relationship with the appearance of the cotton fiber. The fiber ripening process is from banded to twisted fiber and then to a small amount of bent over mature fibers. The pparency of the surface fiber is higher than that of the solid. Therefore, the fibers with poor maturity are banded, with poor reflectivity and poor luster.

About sugar cotton

Sugar containing cotton should be used as a sugar sweetening agent or enzyme treatment before we use it. We should make full use of season and temperature and humidity in spinning mills to solve it. That is to say, in the late autumn, winter and spring, the temperature of the workshop in this season is low. The cotton with lower sugar content is not treated with sugar reducing agent and less enzyme (only 15%). And the principle of using only sugar removing agent instead of enzyme is applied to the high sugar cotton, and the control of the proportion of sugar cotton is controlled by observing and controlling the life stability of the spinning workshop. For

When used in the three seasons of autumn, winter and spring, the temperature is generally controlled at 26 degrees Celsius, and the relative humidity is 58%. The temperature of the two workshops of the drawing and roving is better than 28 degrees Celsius, the relative humidity is 62%, the spinning temperature can be slightly higher, but the relative humidity is good at 52%. It should be noted that in the summer when the higher sugar content cotton is used, it is better to use enzyme treatment, and then use the nose to smell it and sugar free flavor, then it will not be entangled when used. Otherwise, it is necessary to carry out the single mark spinning test. Therefore, the sugar cotton should be used in the three seasons of autumn, winter and spring, so as to ensure the stability of the spinning.

To sum up, the sensory inspection of cotton fiber can determine the inherent quality of cotton fiber according to the appearance of the fiber, and determine the technological properties and value of the textile through the inherent quality of the fiber. The cotton with good quality and good quality should be used properly, and the cotton with poor quality should be used properly, and the use of sugar containing cotton should be fully utilized, and the utilization of raw materials should be fully and reasonably utilized. The utilization rate of raw materials will be continuously improved, and the stable product quality will be produced with less raw material consumption, so as to reduce the spinning cost.
