Chemical fiber standard review meeting was held in Guiyang

From August 23rd to 24th, the National Chemical Fiber Standardization Technical Committee (SAC/TC586) organized a review meeting for chemical fiber standards in Guiyang, from China Chemical Fiber Industry Association, Shanghai Textile Industry Technical Supervision Institute, National Chemical Fiber Standardization Technology Nearly 120 people including members of the committee and the Standardization Technical Committee of China Chemical Fiber Industry Association and industry experts attended the meeting

In terms of method standards, the meeting reviewed two newly developed standards, "Oxygen Index Method for Test Methods of Flame Retardant Properties of Chemical Fibers" and "Test Methods for Intrinsic Viscosity of Spandex Filament Polymers"

The "Oxygen Index Method for Testing the Flame Retardant Properties of Chemical Fibers" is a combination of the "Oxygen Index Method for the Test Methods for the Flame Retardant Properties of Viscose Staple Fibers" (FZ/T 50016-2011) and the "Oxygen Index Method for the Test Methods for the Flame Retardant Properties of Polyester Fibers".

Molecular weight is an important index to evaluate the properties of polymers, which is directly related to the physical and chemical properties such as mechanical strength, heat resistance and solubility of finished fibers

In terms of product standards, 5 revised standards: "Bamboo Pulp for Regenerated Cellulose Fiber", "Pulp for Regenerated Cellulose Fiber", "Bamboo Pulp Viscose Staple Fiber", "Colored Polyester Staple Fiber" And "Nylon 6 High Orientation Yarn (HOY)", the revision of the standard provides technical support for the improvement of product quality

7 standards were formulated: "Narringin Modified Polyester Staple Fiber", "Recycling Sea-island Polyester Drawn Yarn", "Catechin Modified Viscose Staple Fiber", "Colored Polyester Staple Fiber for Vehicle Interiors", " Surgical implant medical grade polyethylene terephthalate (PET) drawing yarn", "acetate staple fiber" and "recycled polyester staple fiber for sewing thread" are all differentiated new products

Naringin and catechin are natural plant extract raw materials, which have certain functions such as antibacterial and deodorizing.

Recycling polyester is a new type of chemical fiber with comprehensive utilization of resources and green environmental protection.

Since the interior of the car is a closed space, and the external use environment is always changing, the standardization of the production and testing standards of colored polyester staple fibers for car interiors as raw materials is particularly important and urgent
.

Medical grade polyester (PET) drawing yarn is mainly used for the production of braided wire due to its good biocompatibility, excellent physical and mechanical properties and chemical stability.
Applied to a variety of medical device products
.
At present, there is no unified technical standard in China, the material supply is monopolized by foreign countries, and the channel and cost factors seriously restrict the development of downstream manufacturers
.

　　The formulation of the above standards is conducive to guiding product production, regulating the market, filling the market gap, improving the market awareness of products, and protecting the interests of enterprises and consumers
.
At the same time, it is beneficial to increase the added value of products and improve the competitiveness of enterprises
.
It has important supporting value and guiding significance for promoting the high-quality development of functional and differentiated fibers
