Overview of machine-picked cotton

1. The difference between foreign machine-picked cotton and domestic machine-picked cotton:

1) The main producing areas of foreign machine-picked cotton are in developed countries with farm-style management such as the United States, Australia, and Brazil, About70010,000 acres of machine-picked cotton.

Features: No foreign fibers, good maturity, good uniformity, low short staple rate, low impurity content, and good consistency.

2) Domestic machine-picked cotton is mainly produced in the Xinjiang Corps (Northern Xinjiang machine-picked cotton accounts for 80% of local cottonAbout 40% of local cotton is machine-picked in southern Xinjiang<spanleft and right); there are very few in the mainland, and there are only a few organic cotton picking demonstration areas for organic cotton picking.

There are about15010,000 acres of machine-picked cotton in China.

Characteristics: poor maturity, high lint rate, high impurity content, three filaments, and snakeskin filaments caused by mulching film mixed into cotton.

2. Overview of machine-picked cotton and hand-picked cotton:

1) Machine-picked cotton:

One-time picking method

1, advantages:

High yield, easy management of cotton picking, convenient transportation, less foreign fiber content, and lower cost than hand-picked cotton (save per kilogram0.5Yuan Dynasty1Yuan Dynasty about).

2, Disadvantages:

Seed cotton has a high impurity content, a large number of various defects in raw cotton, and a high shortness rate in raw cotton (16 %-20%), poor uniformity, low strength, poor maturity, dead cottonThere are many, and the seed cotton processing process is long. There is a lot of noil during spinning and the yarn hairiness is large.

3, spinning adaptability:

General21 carded yarn and open-end spinning yarn with count below, high Reached40branch.

2) Hand-picked cotton:

Layered picking method

1, advantages:

Seed cotton has low impurity content, good raw cotton maturity, less dead cotton, and low short staple rate (22% -12%), good uniformity, relatively high yield.

2, Disadvantages:

It requires a lot of labor, high picking costs, and a lot of foreign fibers.

3, spinning adaptability:

The spinnable count is generally 40, and can be as high as 60Branch left and right.

3. Lint price calculation:

Lint cotton price=[Unit price of seed cotton per kilogram—Unit price of cottonseed per catty*（1—Clothing percentage—Cotton seeds are damaged during processing)]/Clothing ratex2000+Processing fee per ton

For example: seed cotton unit price3.5Yuan /jin, Cotton seed unit price1Yuan/jin, damage and consumption2% , clothing percentage40%, processing fee800Yuan/ton
