How should cotton "three wire" be controlled?

Cotton "three wire" refers to non-cotton fiber and colored fiber that is seriously affected by the quality of cotton and its products mixed into raw cotton, such as chemical fiber, hemp, plastic film, plastic wire, wire rope, cloth, paper and people. Dogs, rats, chickens, ducks and other animal hair and feathers. Because "three wire" has the same light, thin and small characteristics as cotton fiber, it is difficult to remove during spinning, and it is often wrapped or attached to the gauze, which makes the strip dry unevenly, and the number of cotton neps and hybrid plasmids increases. The strength is decreased, the breakage rate is increased, and the production efficiency is lowered; when the fabric is woven, the breakage rate is increased, and the quality of the cloth surface is decreased; when dyeing, the printing effect is not ideal due to the different coloring, which affects the appearance.

The "three wire" problem is a plague that plagues textile enterprises. In order to reduce the impact of "three wire" on the quality of gauze, cotton spinning enterprises have to organize special people to tear the cotton bales in pieces before the cotton is put into production, picking them one by one, and at the same time The various processes of spinning also increase the strength of anti-wire and anti-scratch, which has paid a high price for the cotton spinning enterprises, which has greatly increased the production cost. Despite this, it is impossible to completely control the "three wire" hazard. The situation of missing the "three wire" still exists. The customer complained about the restitution of the compensation incident, which has a great impact on production and operation, so the cotton "three wire" "Control work is both the focus of production cost control and the difficulty of quality control."

First, cotton "three wire" control method

To do a good job of "three wire" control, we must first understand the "three wire" content of raw cotton and the way of production, and then the right medicine.

1. Cotton "three wire" source control.

The main "three wires" such as hair, thread, plastic wire and plastic sheet are mixed with seed cotton during picking, spreading, packaging and acquisition. Therefore, the control of cotton "three wire" source is the focus and most control of "three wire". effective method. There are three main ways to control the source of cotton “three wires”: control of harvesting links, control of acquisition links and control of processing links.

Classification of raw cotton "three silk"

1 harvest link control. Controls including picking, spreading and transportation are mainly done by farmers. There are many cotton producers in China, and the current situation of small, weak and scattered determines that cotton picking mainly depends on labor. This requires cotton farmers to first wear a hat or headscarf to cover the hair, to prevent the hair from being mixed into the seed cotton, to use cotton bags or bamboo baskets to hold cotton, to prevent the use of chemical fiber woven bags, to find agricultural film, plastic Silk and other heterogeneous fibers are removed at any time; secondly, cotton is not spread on the ground, and it is not spread on items that are prone to foreign fibers, preventing animals such as dogs, cats, chickens, ducks from entering the sun-baked cotton; the third is when transporting cotton. Cotton is wrapped in a cotton cloth and tightly covered to prevent foreign matter from falling into the air.

2 acquisition link control. Mainly relying on cotton processing enterprises to complete, first of all require staff and cotton farmers to enter the acquisition area, wear a good working hat, not leaking, to avoid falling into the cotton; Second, cotton farmers use white cotton cloth, no chemical fiber Rope and colored rope ties are strictly prohibited. Chemical fiber woven bags are strictly prohibited. Thirdly, when the cotton is smashed, the “three wire” is selected one by one, and the cotton containing “three wires” is especially stored separately, and it is picked or rejected separately.

3 processing link control. The "three wire" control of the processing link is mainly divided into three steps: First, before the processing, special personnel are arranged to pre-roll the seed cotton according to the standard picking method, and the seed cotton is selected according to the quota, and the transfer management is carried out conditionally; secondly, the seed cotton is rolled. When feeding flowers, pick them at any time and try to avoid night processing to ensure quality. Third, optimize the ginning process during processing, strengthen cotton impurities, remove foreign matter, and control the quality of cotton processing.

2. Cotton spinning enterprise "three wire" control.

Although everyone has realized the importance and feasibility of the control of cotton “three wire” source, but most of the cotton fields in China are scattered, cotton farmers, cotton mills, spinning mills and other departments lack the necessary communication and corresponding preventive measures, cotton “three The control effect of the silk source is not obvious, and the "three wire" is still a problem that cotton spinning enterprises can't avoid. In order to reduce the harm of "three wires", various cotton spinning enterprises have invested a lot of manpower, material resources and financial resources in the "three wire" control. In the first half of 2006, a cotton spinning mill picked up more than 5,000 tons of raw cotton in the “three wire” workshops. The wages alone paid more than 1.4 million yuan, and the cost per ton of cotton increased by more than 280 yuan. "Control has become the focus of cotton spinning enterprises.

1 Pay attention to the "three wire" source control. Strengthen cooperation with cotton processing enterprises, establish a fixed raw cotton supply base, formulate the “three wire” control standard for raw cotton procurement, pre-inspect the batch of raw cotton by batch in proportion to 5%, and “three wire” exceed the standard raw cotton for price reduction or return processing. .

2 Adopting the sea tactics to pick "three wires." Some mills have more than 50 employees in the "three wire" employees. In the work, the "three wire" picking operation method is strictly regulated, and the method of picking, rechecking and spot checking is adopted to ensure the input of raw cotton. The “wire” indicator meets customer needs.

3 Strengthen production management. The production variety is accurately positioned, and the whole line produces pure cotton products, ensuring a production environment with no heterogeneous fibers. At the same time, it strengthens the efforts to capture the anti-wire effect of the various processes, and participates in the whole work, and makes concerted efforts to share the "three wires."

4 Use the instrument to check off. In the cleaning process, the foreign fiber automatic sorter is installed, and the foreign fiber shearing system is installed on the automatic winder to eliminate the danger of missing the "three wires".
