New Announcement Of New Cotton Quality In China

　 In the past few years since the reform and development, China's instrumental notarization work has been continuously deepened, and the inspection volume has steadily increased. At present, the total amount of cotton circulation is nearly 40%, and the test data can truly reflect the annual quality of cotton in China.

China's new cotton quality bulletin in 2009/2010, new system in 2009 cotton Based on the inspection data, statistics and analysis are carried out in order to get valuable information and provide an important basis for government cotton management departments and cotton enterprises to analyze cotton situation, research cotton policy and support cotton industry.

A survey of the new system of cotton notarization inspection

In 2009, the new system cotton certification test volume reached 11 million 304 thousand packets 2 million 552 thousand tons [1], coverage rate (the ratio of inspection volume to production, the same below) 39.9%[2]. A total of 1459 processing plants and 1594 production lines were involved in the inspection, with an average of 1749 tons per processing plant.

(1) annual changes in inspection volume

Since the beginning of 2006, the number of processing plants participating in the new cotton certification test has increased year by year, with an average annual growth rate of 52.4%, of which 20.6% increased by 20.6% over the same period in 2009. Since the beginning of 2006, the new cotton certification test volume and coverage have increased significantly, the annual growth rate of inspection volume is 77.1%, and the coverage rate has increased by 9.5 percentage points annually. Influenced by factors such as the base number in 2008 and the cotton production and market in 2009, the inspection volume in 2009 decreased by 40.2% compared with the same period last year, and the coverage rate decreased by 17 percentage points.

(two) geographical distribution of cotton in the new system

In 2009, a total of 14 cotton producing provinces participated in the new cotton certification test, of which Xinjiang accounted for the largest volume, accounting for 71.2% of the national inspection volume. The main cotton producing provinces in the mainland are: Shandong (9%), Hebei (5.5%), Hubei (4.5%), Gansu (2.3%), Jiangsu (2.3%), Anhui (2.1%), Hunan (1.6%), Henan (0.6%). Other cotton producing provinces accounted for 0.9% of the total volume of cotton inspection in the new cotton certification test. According to the volume of inspection, they were Jiangxi, Zhejiang, Shaanxi, Tianjin and Shanxi.

(three) monthly distribution of new cotton inspection cycle

The notarization test of new cotton in September started from September, and basically ended in May. The peak period was concentrated in October, November, December and January.

The inspection of Xinjiang cotton began in October, and Shandong cotton, Hebei cotton and Hubei cotton were tested in September.

The overall quality of new cotton in two and 2009

(1) quality index Test result

The main quality indicators of new cotton in 2009 include grade, length, micron level, fracture strength and length uniformity. The grade is divided into 7 grades: Cotton with moderate maturity, good color, and high cotton quality, which are concentrated in grade 1-2 (hereinafter referred to as high grade). The 3 grade is the standard grade, and the 5-7 grade (hereinafter referred to as the low grade) indicates that the cotton grade is very poor, the comprehensive index is the average grade, the length grade is divided into 8 grades, the cotton length is concentrated in 30-32 millimeter level, the 28 millimeter level is the standard grade, the 25-27 millimeter level indicates that the cotton length is very short, the comprehensive index is the average length, the micron value level is divided into three grade five files [3], the higher the micron value indicates, the thicker the cotton fiber is, the higher the maturity degree is. The cotton with micron normal value is concentrated in Grade A and B, and the grade A is the best. C1 shows that cotton fiber is very fine or immature. The breaking strength is divided into five grades. The cotton with strong tensile strength is concentrated in strong and strong ranks. The length uniformity is divided into five grades. According to the 2009 annual inspection results, the national grade and length are close to the standard grade, and the distribution of micron values is moderate and high.
