How Should The Relevant Departments Of Cotton Issue The New National Standard?

< p > November 14, 2012, < a href= "http://www.91se91.com" > cotton < /a > fine cotton "GB1103-2012" will be formally implemented in September 1, 2013. The original fine cotton national standard (GB1103-2007 "cotton fine cotton") will no longer be used.

< /p >

< p > compared with the original standard, the new standard stipulated 9 cotton quality indicators: grade, length, micron value, moisture regain, impurity content, fracture strength, length uniformity index, hazardous debris and color characteristics.

Among them, the grade is determined by three indexes of cotton "maturity, color characteristics and mill quality", and is divided into 1~7 grades.

The new standard includes 11 quality indicators, including color level, mill quality, length, micron value, moisture content, fracture strength, length uniformity index, hazardous debris, reflectivity and yellow depth. The grade is abolished, the color level and the quality index of rolling quality are increased, and the color level is divided into four types and 13 color grades: white cotton, light spot cotton, light yellow cotton and yellow cotton.

The color level is based on the physical standard, and the color level is determined by comparing the reflectance and yellowness.

According to the information from the China Cotton Association, information shows that when each paction is calculated according to the original standard, each differential price will fluctuate by about 3%.

According to the new standard, the price difference of the same color grade cotton is (300~500) yuan / ton, and the price difference of different grade and color grade cotton is 1000 yuan / ton.

The publication of < p > a href= "http://www.91se91.com/news/index_q.asp" > New Standard < /a > has abolished the grade examination conducted in China for 40 years, and carried out a brand-new cotton color grading test.

Because of the color grade instead of grade, the change of cotton technical index will directly affect the cotton trade settlement rules in China, and will also affect the development of cotton industry in Bo Zhou.

How to better cope with the impact of the implementation of the new national standard of cotton on the cotton industry in our state is a problem that we need to think about and solve at present.

Here, as the professional fiber inspection institution of cotton quality supervision in our state, the bole Fiber Inspection Institute puts forward the following suggestions for reference by relevant departments: < /p >

The first is to choose the best cotton varieties, while ensuring the output while ensuring the quality of cotton, reducing the speed of degradation of cotton varieties, giving priority to selecting suitable varieties for planting and popularizing; two, strengthening the scientific management of cotton fields and promoting the publicity of cotton quality; and three, increasing the propaganda efforts of "four points" (picking, drying, storing and distributing) of cotton farmers to achieve high quality and high price; and four, picking cotton in time, because the picking period has a certain effect on the color of cotton, and the research data show that the exposure time in the field has an effect on the color of cotton. The cotton on the same site is the same on the same day, and the deeper the cotton is, the deeper the color is. < p > top priority of the agricultural sector

In short, there are many factors that affect the color variation of cotton, such as storage time, temperature, humidity, variety, microorganism and so on.

< /p >

After the implementation of the new standard < p >, cotton processing enterprises should attach great importance to and strengthen their study.

From the person in charge of the enterprise to the inspector, we should first study the new standard carefully and understand the new standard.

There are many factors that affect the color variation of cotton, such as storage time, temperature, humidity, variety, microorganism and so on.

Therefore, processing enterprises need to understand the above factors while implementing new standards.

For the inspection of seed cotton acquisition process, the processing enterprises need to use small sawtooth cotton gin after trial rolling, use sensory inspection method to test the color level.

When inspecting the color grading of cotton, the inspectors must conscientiously study and practice and develop a sense of cotton color so as to accurately judge the slight changes in color.

Through color, it feels the formation process and use value. This feeling is accumulated by long-term practice.

In addition, cotton processing enterprises in the acquisition link, we must stop buying super water cotton, because cotton regurgtion rate is too high, will accelerate the speed of color variation of cotton.

< /p >

At present, the publicity and training work of the new standard has already begun. It is recommended that governments at all levels should seize the time and actively disseminating new standards to the vast majority of cotton farmers, ginning enterprises and cotton seeds, such as "a href=" http:// www.91se91.com/news/index_s.asp "," sales /a "units and agricultural technology extension personnel, in accordance with the division of responsibilities of departments, and through various forms of news media and organizational training, so as to learn new standards and respond to the impact of standard changes on our cotton industry as early as possible."
