F55

Name and positioning. The documentation page is titled "Negative Ion Agent F55", applied to the negative ion functional direction of the chemical fiber industry; the product catalog line records "F55: Negative Ion Agent". (Data source: product handbook / official product data)

Overview (verbatim excerpt): "This negative ion agent has a release amount of 20000 and is widely used in the chemical fiber industry. Natural, odorless, non-toxic, and with good safety. The product has the effects of purifying air, eliminating human fatigue, and promoting human health. In addition, this series of products also has antibacterial and sterilization effects, and has an obvious deodorizing function. When this product is used in fibers and clothing woven from them is worn on the human body, it can continuously emit negative ions toward the human body, keeping the human body energetic; on the other hand, it can continuously eliminate for the human body various internal wastes excreted by the body. At the same time, clothing with this function will not reduce its effect due to frequent washing." (Data source: product handbook)

Four main functions. The documentation lists four items: ① Air purification ("negative ions move in the air to form a 'Z' shape"); ② Eliminate indoor odors and various harmful gases (for irritating gases such as benzene, formaldehyde, ketones, and ammonia volatilized from decoration materials, negative-ion-containing wall coverings, curtains, etc. "can all effectively eliminate them"); ③ Healthcare effect (clothing, bed sheets, wallpaper, carpets, and coatings containing negative ion agents, etc. "have dual functions of healthcare and environmental protection"; in bathroom scenarios, it accelerates molecular movement and turns ordinary water into activated water); ④ Water treatment (in scenarios where it is added to filter materials for water dispenser filter cartridges). (Data source: product handbook)

Addition scenarios. The documentation records "can be added during the manufacture of nonwovens and curtains"; used in scenarios such as fibers for weaving clothing, interior decorative fabrics, and coatings. (Data source: product handbook)

• Release amount: 20000 (value recorded in documentation).
• Safety statement (verbatim): natural, odorless, non-toxic, and with good safety.
• Washing resistance statement (verbatim): "Clothing with this function will not reduce its effect due to frequent washing."
• This grade is a historically listed grade (Discontinued), documentation is retained; this page is compiled as-is from historical documentation.

The documentation does not list a separate mechanism section; according to the statements in the overview and main functions, the functional path of this product is: after the negative ion agent is added to fibers or materials, it continuously emits negative ions to the environment and the human body. (Data source: product handbook)

Purification path (as stated in the documentation): negative ions move in the air; the negative charges they carry combine with bacteria, dust, smoke particles, water droplets, etc., aggregate into clusters, and settle, thereby achieving the purpose of air purification; the same applies to irritating gases volatilized from indoor decoration materials. (Data source: product handbook)

Application-side highlight: the documentation emphasizes that this function "will not reduce its effect due to frequent washing". (Data source: product handbook)

1. Addition —— added within fiber / materialUsed in fibers, woven clothing, or added to wall coverings, curtains, coatings, filter materials, etc.
2. Excitation —— continuous release of negative ions to the human body and the environment"continuously emit negative ions toward the human body, keeping the human body energetic".
3. Effect —— purification · deodorization · healthcare · water treatmentNegative charges combine with particles into clusters and settle; eliminate odors and harmful gases; fabrics and coatings have dual functions of healthcare and environmental protection.

The table below summarizes the key points of the F55 entry as recorded in the source (the values in the table are those recorded in the source).

This grade's entry does not list a physicochemical properties table, toxicological and safety data, or specialized tests; items not recorded in the source do not appear in this table. (Data source: product handbook / official product data)

To state the conclusion clearly first: the source for this grade does not provide a dosage column ⇒ this page gives no dosage values and does not draft a denominator on its behalf. The actual findings are as follows:

Two points must be clearly stated. First, the source does not give a dosage range or scenario-specific values ⇒ there is no value to cite, and this page does not fabricate one. Second, this grade has no thickness-dosage or loading-dosage directional clause—the source has no such wording, and this page neither writes one nor applies directional conclusions from other grades. (Data source: product handbook / official product data)

This entry truthfully explains the missing item: dosage values can be placed on the page only after the source is supplemented; this page gives no range and no denominator. (Data source: product handbook / official product data)

The applications and addition scenarios listed in the source are as follows:

Chemical fiber / Fiber

Used in fibers; when woven into clothing and worn on the human body, it continuously generates negative ions.

Indoor materials

Wall coverings, curtains, etc. containing negative ions; fabrics processed with negative-ion fibers, such as clothing, bed sheets, wallpaper, and carpets; coatings containing negative-ion agents.

Nonwoven fabric / Curtain manufacturing

The source states, 'It can be added during the manufacture of nonwovens and curtains.'

Water treatment scenarios

Added to filter materials for water dispenser filter cartridges; bathroom towels made from negative-ion fibers or used for bathroom water treatment.

F55 belongs to the chemical fiber and functional materials direction. Adjacent functional additives in the same volume vary in direction; select by function. Comparison as follows:

Reading note: The comparison only explains each grade's data positioning and intended use; the three grades have different functions and different dosage bases, and their values are not interchangeable. (Data source: product handbook)

The following points are taken item by item from the recorded data; items not listed in the data are not drafted on their behalf.

The data on this page come from product documentation and can be traced item by item:

• Product handbook: F55 entry (overview / four main functions / packaging); product catalog line and adjacent entry sections (positioning sentences for DD550, S38, etc.).
• Cross-verification of data: the same grade's entry has consistent excerpts across three sources—the handbook, the comprehensive series volume, and the content-edited version (single source family; three volumes cross-verify).

Not covered by the source material (not written on this page — to be added later)

• Dosage: this grade's data source has no dosage field ⇒ this page does not provide a numerical value.
• Physicochemical properties table, storage conditions, shelf life: not listed in this grade's entry ⇒ not drafted on its behalf.
• Prohibited items and safe handling data (MSDS level): not recorded in the available data.
• The Chinese fragment 'zhong xijun' (bacteria-related) and other wording are as in the source (the text appears to have missing characters)—transcribed without modification; the relevant statements are not cited as indicators on this page.

F55 is listed as a discontinued grade; the documentation is retained. This page is compiled from historical source material and is not a recommendation of a currently supplied product; please base your selection on current production grades and the latest documentation.
