Cotton fiber

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.棉纖維的光澤：棉纖維的光澤與成熟度，手感彈性之間有著密切的關(guān)系，棉纖維系半透明體物質(zhì)，其光澤直接反映它本身的內(nèi)部結(jié)構(gòu)和外觀形態(tài)，又是其成熟度的具體體現(xiàn)，它又與纖維的手感性質(zhì)直接相關(guān)，棉纖維的內(nèi)部結(jié)構(gòu)從微觀結(jié)構(gòu)來(lái)說(shuō)，它不是單晶體，而是由大量微晶體和無(wú)定形區(qū)所組成，它們的取向一般平行于纖維軸線，纖維的取向度高，纖維的分子排列整齊，透明度就高，纖維的反光性就強(qiáng)，纖維的光澤就好，纖維的成熟度就好，由于棉纖維是大量的微晶體和無(wú)定形區(qū)所組成，再加上空心形態(tài)，所以決定了它本身具有半透明和半彈性的良好性質(zhì)，由于棉纖維的成熟過(guò)程是隨著纖維素淀積細(xì)胞壁加厚而完成的，所以正常成熟的棉纖維它的光澤是由差到好又變成較差的，纖維的手感也是由塑軟性變?nèi)彳浶裕內(nèi)峄?，變成彈柔性最后形成粗剛性?/p>

The quality of 3. cotton fibers is good or bad.

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.
