Process knowledge in flame finishing fabric finishing

Multi-functional flame retardant fabric is anti-mosquito, anti-static, anti-UV, waterproof, anti-oil, anti-chemical substances, easy to decontamination, film composite and other technology, with anti-mosquito, anti- Breathable, warm, water pressure, anti-ultraviolet and other functional fabrics. Flame retardant fabrics: Flame retardant fabrics: Flame retardant fabrics: Flame retardant fabrics (Flammable fabrics, Flame resistant fabrics, Flameproof fabrics, Flameproof fabrics, Flame- The same time as
Function refers to the processing of multi-channel process to achieve the textile fabric has the product performance, after processing involved in the special section, how to do these functional fabrics, first of all from the source, the source is the spinning weaving dyeing, thus To ensure the stability of the latter part of the product quality and durability. With the Division I cotton cotton / Nylon (cotton) flame retardant fabric into the American market in large quantities, more and more people began to look at the Chinese manufacturing. How to achieve high-tech textile content and value-added it? Which requires us to give it a unique function; but how to achieve these special features? The same time as
1, textile Spinning + Weaving
(1) yarn: the quality of the yarn quality determines the quality of the fabric, the strength of the fabric to determine the quality of tearing. Friendship prompts you, on the flame retardant fabrics EN11611 and EN11612 are broken and torn made a clear numerical requirements, and IEC61482 also has a strong requirement, but more humane, lists the different grades of grade requirements. (Chemical fiber yarn yarn used to represent D, denier number, the international commonly used to indicate the fineness of chemical fiber and natural silk; tear: the better the strength of the test yarn, wear resistance, better resistance, Work environment to protect the role of the human body).
(2) Textile: yarn in the textile machinery weaving into the fabric process, adjust the machine, to reduce the fabric crossing, broken by the weft, holes, deduction and other defects.
2, printing and dyeing Dyeing
Dyeing and finishing plant color must be in the acceptance, and can not have yin and yang, cloth quality qualified, the other is to talk about important physical performance test
(1), feel: soft, Proban flame retardant fabric feel some hard, Xinxiang Yulong currently developed a new product feel improved, but some guests like the fabric to be more soft. Pyrovatex is good, but the cloth smells big.
(2), weft oblique: American standard test standard ASTM D3882 dyeing cloth requirements are effective width of 3%, lattice cloth and printing cloth requirements is effective width of 2% for qualified products. (Latitude, if more than the US standard range easily lead to clothing after washing deformation distortion, lattice cloth printed cloth grid asymmetry, unsightly).
(3), density: American Standard ASTM D3775 requires latitude and longitude density within ± 3% qualified.
(4), weight: American standard test ASTM D3776, required within ± 5% qualified. The same time as
(5), PH: American standard test AATCC-81 requires 4.5-7.5 (weak body acidic, so the provisions of the weak acid range for the human body, if the alkaline, the skin is susceptible to dry and uncomfortable).
(6), tear strength: American standard test ASTM D1424, according to the specific requirements of different varieties of fabric (tear with kg KG, pounds LB, Newton N said its cloth latitude and longitude test value, tear good or bad, affecting the clothing Wear-resistant wear resistance). (7), elongation strength: American standard test ASTM D5034, according to the specific requirements of different varieties of fabric (kg kg, pounds LB, Newton N said its cloth latitude and longitude test values, elongated strength is good, affecting the clothing resistance Wear wear resistance). (8), seam slip: American standard test ASTM D434, according to the specific requirements of different varieties of fabric (with MM that its test value, seam strength is good or bad, affecting the clothing patchwork slip). The same time as
(9), shrinkage: American standard test AATCC-135-3 requires latitude and longitude to ± 3%, (shrinkage if more than 3%, affecting the size of several times after the clothing washing water).
(11), friction color fastness: American standard test AATCC-8 requirements: dry grinding 4, wet grinding 3. (This requires the degree of fading of the fabric). The same time as
(10), light fastness: American standard test AATCC-16E requirements: a specific lamp 20 hours irradiation 4, 40 hours irradiation level 3 (mainly resistant to sunlight, generally wearing outdoor clothing to prevent the sun is not easy to change color, in case of danger , Its eye-catching clothing color, waiting for rescue convenience). The same time as
(12), water fastness: American standard test AATCC-107 requirements: discoloration 4, stained 3. (This requirement through the cotton, nylon, polyester, wool, acrylic, vinegar and other cloth test to see the color change, stain rating). The same time as
(14), perspiration color fastness: American standard test AATCC-15 requirements: color 4, stained 3. (This requirement through the cotton, nylon, polyester, wool, acrylic, vinegar and other cloth test to see the color change, stain rating). The same time as
(13), machine washing color fastness: American standard test AATCC-61-2A requirements: color 4, stained 3. (This requirement through the cotton, nylon, polyester, wool, acrylic, vinegar and other cloth test to see the color change, stain rating). The same time as
Note: Light fastness is the focus of certain regional assessment, such as Singapore, Australia and other markets. AATCC and ASTM are the United States test standards, JIS for the Japanese test standards, ISO for the European testing standards, GB for the Chinese standard, the international standard for the United States the most common standards, the Chinese national standard test requirements for the lowest value; Fabric fabric color fastness, up to 5, the lowest level 1, judge the color level is the standard gray card.

3 Finishing FR Finishing
For the latter part of the fire finishing, the main use of the following two finishing methods
1, PYROVATEX: Pyrovatex CP New Flame retardant treatment technology to deal with the fabric has a good washing performance, in general, 50 times the flame retardant specifications are still within the standard requirements. In addition, Pyrovatex CP New processing of the fabric feel soft, no smell, but also to Europe's Oeko-Tex Standard 100 environmental standards, the Department of green flame retardant products and harmless to the human body. Technology can also be anti-oil and water, anti-wrinkle treatment technology combined to produce a multi-functional flame retardant fabric. Huntsman brand Pyrovatex CP New cotton flame retardant treatment technology, is the Swiss Ciba Fine Chemical Company's patent. The principle is to use Pyrovatex CP New patented flame retardant chemical additives and its technology to deal with cotton fiber fabric, greatly shorten the duration of burning and smoldering and quickly self-extinguishing, and has a flame retardant performance. Disadvantages: strong damage large (15-20%), the dye must have a choice, the cost is too high. Advantages: good flame retardant properties of formaldehyde ≤ 300ppm environmental indicators meet the requirements, feel soft, flame retardant after the impact of the original color fastness.
2, PROBAN: Proban Flame retardant treatment technology to deal with the fabric has a good washability, if properly maintained, how long the service life of the long flame retardant performance, in general, 50 times its flame retardant indicators are still Within the standard requirements. In addition, Proban deal with the fabric feel soft, no smell. Rhodia's brand Proban cotton flame retardant treatment technology, is the French company Rhodia's patent. The principle is the use of polyphosphate chemical additives and unique finishing process for cotton fiber fabric processing, the fabric heat up carbonization, the formation of isolation layer, the fabric immediately back to stop burning, to self-extinguishing, so that the burning and smoldering time pole Short and has flame retardant properties. Disadvantages: formaldehyde content> 300ppm, not environmentally friendly, feel rough, flame retardant after the impact of some of the original color fastness, the dye must be selected. Advantages: good flame retardant performance, strong damage small (10%), low cost The same time as
Finishing fire on the fluorescent color has been troubled by everyone's difficulties, fluorescent, flame retardant two balance points, all manufacturers are difficult to solve. Yulong Textile Company's strong R & D technical team, through unremitting efforts to launch a flame-retardant fluorescent yellow fabric, flame retardant properties and fluorescent colors fully meet the standard requirements. Cotton and CVC finishing yellow after finishing this difficult to be successfully overcome.
