Standard "Square Circle"

In the "12th Five-Year" guiding ideology and development goals of scientific and technological progress in textile industry, textile standard research was included.

In particular, in a number of key areas, such as new textile materials, eco textiles, functional textiles and high performance textiles, as soon as possible, a batch of satisfaction can be formulated.

Recently, it is used by Chinese industry.

The "short board" standard of textile industry is the industry standard of textile industry.

It has such problems as lag behind in standard setting, no standard production, and poor detection means.

At the recent organizing conference of China Industrial Textile Industry Association, the most heard is the reflection of the lag of the industry standard in the production enterprises.

For example, if calcium carbonate is added to spunbonded nonwovens, some people are against adding that excessive addition will result in a strong reduction in product quality and no guarantee of quality. Some people support the idea that proper addition can reduce cost and benefit environmental degradation.

The focus of divergence is actually that there is no industry standard, which leads to confusion between enterprises and production and sales.

The spunbonded nonwovens enterprises have been implicated in some good quality and good benefits.

The company representatives strongly urged that we should speed up the formulation of spunbond nonwoven standards and stop over adding calcium carbonate.

This standard drafting and approving experts and committee members have conscientiously reviewed the trade standards of spunbonded nonwovens and hot-rolled nonwovens, and put forward amendments to provide scientific basis for the production and product testing of spunbonded nonwovens industry.

It is understood that the standard of spunbonded nonwovens and hot rolled nonwovens is the revision of the original "thin sticky nonwovens" standard.

The original standard includes three parts: impregnated bonded nonwovens, hot-rolled adhesive bonded nonwovens and spunbonded nonwovens.

The original standard has been used for more than 20 years, and can not meet the current production needs.

The revision is based on hot rolled sticky nonwovens and spunbonded nonwovens as standardised standards to meet the needs of the development of the industry.

In 2007, the state issued the plastic limit order, and the spunbonded nonwoven shopping bags became the first choice for supermarkets and shopping malls, thus promoting the rapid expansion of the spunbonded nonwoven industry.

For a time, the spunbonded nonwovens equipment was surging up from more than 200 production lines to more than 900 production lines.

After the gust of wind, the spunbonded hot rolled nonwovens industry was forced into the dilemma of overcapacity and homogenization competition.

Spunbonded nonwovens are mainly polypropylene and polyester products.

The product has the characteristics of high strength, small difference in anisotropy, good stability and permeability, corrosion resistance, sound insulation, moth proofing, non-toxic and so on.

It can be used in medical disposable surgical gowns, caps, mattresses and masks, personal hygiene products, covering materials for agriculture, and other shopping bags for making repeated use.

The approved "nonwoven shopping bag" standard heard the opinions of Shaoxing county and China Synthetic Fiber Co., Ltd., Shaoxing County Zhuang Jie Nonwovens Materials Co., Ltd., Foshan Nanhai fixed defoy nonwovens Co., Ltd., Shandong Junfu nonwovens Co., Ltd., Wenzhou Changlong Textile Technology Co., Ltd., and made unified standards for the material, weight, environmental protection and testing of nonwoven shopping bags, which is convenient for production enterprises to refer to.

The standard of sodium bentonite composite waterproof liner is a newly revised standard.

According to Zhao Jinyu, Gao Gong, an industrial textile industry association, the sodium bentonite composite waterproof liner is a new type of geosynthetics made up of specially made plastic flat weave knitted fabric and nonwoven fabric filled with highly expansive sodium bentonite.

This kind of geotextile will form a uniform high density colloidal waterproof layer in the liner after encountering water, which can effectively prevent water leakage.

Sodium bentonite composite waterproof liner is widely used in subway, tunnel, artificial lake, landfill, airport, water conservancy, Luqiao, building and other fields.

At present, the annual production capacity of China's waterproof liner manufacturers is 50 million to 60 million square meters.

As the saying goes, no rules, no Cheng Fangyuan.

The standard is too important, it is like a ruler to measure the production and sales situation of production enterprises. It is like a threshold to keep the fake and inferior products outside the industry.

In the "12th Five-Year plan" of industrial textiles, we will formulate corresponding standards for high-tech fibers and new textile materials, such as PBO fiber, polyimide fiber, aramid fiber, UHMWPE fiber, carbon fiber, polyphenylene sulfide fiber and so on.

By 2025, the establishment of a new standard system for industrial textiles will be completed, and the industrial textiles industry, which contributes to the textile power, will become an important strategic pillar industry.
