Eight production requirements for anti-static tooling fabrics

Anti-static tooling fabrics bear the heavy responsibility of protecting the safety of industrial workers. It is of great significance and slight inadvertence may have a huge impact. Blue Sky knows that only from raw material selection and production source checks can it truly guarantee the anti-static properties of the tooling fabrics. stable. For this reason, after nearly two decades of practical experience accumulation and summarization, the leaders and experts of the special fabric R&D center of the Jiangnan branch of the China Textile Academy specially formulated the selection of conductive fibers, choice of conductive materials, and conductive fibers. The eight production requirements for content, cotton yarn selection, thread twist control, weaving requirements, printing and dyeing, and storage are strictly enforced in the production process to improve the stability of the fabric's anti-static properties.

1. Conductive fiber: After more than a decade of use of conductive fibers by well-known companies at home and abroad, the company has demonstrated that the inner-coverage polyester (polyester fiber)-based conductive fiber is superior to nylon (nylon) in light, heat, and acid resistance. Based on the conductive fiber, since the conductive particles of the fiber are contained in the fiber, the friction resistance and washing resistance of the conductive fiber are significantly better than the covered conductive fiber in which the conductive particles are exposed on the surface of the fiber. Therefore, the company will have excellent conductive properties and a long-lasting built-in polyester. The base conductive fiber is used as special fiber for "Blue Xiang" anti-static (safety protection) tooling fabric.

2. Conductive materials: Combining different requirements for electrostatic safety protection of garments in different countries, different industries and different occasions, the company selects different types of built-in polyester-based conductive fibers and their corresponding base yarns, which are manufactured through special processes and lines. Made of conductive material.

3, conductive fiber content: According to different occasions on the different requirements of fabric anti-static performance indicators, combined with different fabric weight, different organizational structure, choose ANSET brand and other conductive materials, formulate a different amount of conductive material and interweave or inlay Different weaving processes.

4. Cotton Yarn: At present, the “Yanxiang” anti-static (safety protection) tooling fabrics consist of cotton, cotton and polyester fibers, polyester and cotton. The material and production are strictly controlled:

(1) The length of cotton fiber will have a direct impact on the length of hairiness of the yarn. If the use of cotton is reduced in order to reduce costs, the production of cotton yarn hairiness will increase. Hairy feathers are prone to static electricity in friction, which will neutralize and weaken the conductive properties of conductive fibers. At the same time, hairiness floats on the surface of the fabric, making the conductive fibers more covered, thus reducing the elimination of conductive fibers by corona discharge. The effect of static electricity.

(2) The thickness of polyester staple fiber (polyester fiber) will directly affect the amount of ball played in the fabric. For example, excessively fine fibers tend to produce fabric pilling. Similarly, too many hair bulbs will neutralize and weaken the conductive properties of conductive fibers. In addition, thinner fibers have a larger surface area ratio and are therefore more prone to static electricity.

(3) The degree of yarn twist will affect the amount of feathers produced. Yarn production enterprises in order to meet the needs of woven and knitted different customers at the same time, the production of a twist between the knitting and weaving standards in the middle of the yarn, because the twist of this type of yarn is significantly lower than the standard woven yarn, resulting in more hairiness yarn.

5. Lines: In order to reduce costs, a few merging plants use reduced parallel ties to increase production. Low turbulence leads to more hairiness on the line. Excessive hairiness will neutralize and weaken the conductive properties of conductive fibers. In accordance with the "Lan Xiang" fabric line requirements for production.

6, weaving: (1) warping, the size of the weaving tension has a greater impact on the floating point of the fabric in the fabric, floating point and more conductive properties of the fabric is relatively good. (2) The quality of the slurry and the sizing process will directly affect the adhesion and smoothness of the yarn hairiness. The yarns with poor adhesion and smoothness tend to produce hairballs during the weaving process. The ball will neutralize and weaken the conductive properties of the conductive fiber. (3) The reasonable adjustment of the brown frame and the selection of the steel buckle.

7, printing and dyeing: strictly according to the "blue Xiang" anti-static fabric "processing precautions" for printing and dyeing process, the printing and dyeing process of the desizing process, oxygen bleaching process, mercerizing process, stereotypes process has strict regulations to ensure that the printing and dyeing process fabrics Antistatic performance is stable.

8. Storage: In order to ensure the stability of the anti-static (safety) protection of the tooling fabric, conductive fibers, conductive materials, anti-static grey cloths and anti-static color cloths must not be stored in corrosive materials such as strong alkalis or strong acids during production and storage. Together, the storage should be dry and ventilated, and the product should be more than 30cm away from the wall and floor to prevent rat bites, insects, and mildew.

“Providing safety, health, and comfort to industrious and intelligent industrial workers.” is the consistent aim of the company. The eight production requirements are an important step for Blue Sky China to create an expert company, and will comprehensively improve the quality of the company’s products. The stability of anti-static performance has become Blue Sky's corporate mission of ensuring the safety of industrial workers and enhancing the overall competitiveness of the “Blue Xiang” anti-static tooling fabric industry in the market economy.
