SR-FB-103 is an antibacterial finishing agent for cotton, polyester, nylon, and their blended or union fabrics. It is especially suitable for garment linings, sportswear, workwear, bed covers, quilts, shirts, tops, skirts, garment accessories, floor mats, and similar products.<\/span><\/p>\n

Even at low concentrations, SR-FB-103 inhibits both Gram-negative and Gram-positive bacteria.
Testing has confirmed that SR-FB-103 provides marked inhibition of the following microorganisms:<\/span><\/p>\n

Gram-positive bacteria: hemolytic streptococci and Staphylococcus aureus
Microorganisms associated with perspiration: Staphylococcus saprophyticus, Bacillus subtilis, and Corynebacterium diphtheriae;
Gram-negative bacteria: Escherichia coli;
Enteric pathogens: Salmonella enterica and Klebsiella pneumoniae;
Skin microorganisms: Staphylococcus epidermidis and micrococci;
Fungi: Candida albicans and Trichophyton species<\/span><\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

<\/strong><\/span>Recommended formulations:
<\/span>(1) 100% polyester: heat-set the fabric before dyeing. Apply using a high-temperature dyeing process.
<\/span>\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 Liquor ratio: 1:20
<\/span>\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 5% SR-FB-103
<\/span>\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 X% disperse dye
<\/span>\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0Appropriate amounts of dispersing and leveling agents<\/span>
Process:<\/span>Raise the temperature from 20\u00b0C to 130\u00b0C at 1\u20131.5\u00b0C\/min, hold at 130\u00b0C for 30 min (depending on shade depth), then cool, wash with hot and cold water and, if necessary, reduction-clear, rinse, neutralize, and dry.
A one-bath process is recommended for antibacterial finishing of polyester\/cotton blends.

\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 Appropriate amounts of retarding agent and other auxiliaries
<\/span>Process:<\/span>Raise the temperature from 20\u00b0C to 95\u00b0C, hold at 95\u00b0C for 60 min, then cool, wash, and dry. Dosage: 2\u20133%. <\/span><\/p>\n

(3) Cotton fabrics<\/span>
1. For pad-dyeing, prepare SR-FB-103 at 10\u201340 g\/L. Use one dip and one nip at a 70% wet pickup, then dry under standard process conditions.
<\/span>2. For exhaust application, use SR-FB-103 at 1\u20132% owf with a liquor ratio of 1:15\u201320. Treat at 50\u201360\u00b0C for 30 minutes, then dry under standard process conditions.
<\/span>3. For spray application, use SR-FB-103 at 1.0\u20133.0% owf, diluted tenfold. Ensure an even spray application and heat-dry at 80\u2013100\u00b0C.<\/span><\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
