Performance mechanism and research progress of flame retardant and antistatic fabrics

Therefore, the author believes that for polyester-cotton composite fine-denier fibers, the expected results cannot be achieved without fiber opening. The author also provides the following process flow: seaming – fine washing – fiber opening treatment – untwisting and open width drying – shaping and tentering – sanding and raising – dyeing – open width drying –Anti-static resistor Burning cloth-Softening treatment-Finished product.

The author believes that in order to obtain high quality products, attention must be paid to fiber opening, sanding, dyeing and anti-static finishing processes, and low tension equipment should be selected for processing. As far as the process parameters are concerned, the seam removal head should use spread stitching, the needle density is 26-30 stitches/10cm, and the edge density is 9-11 stitches/2cm. During fine cleaning, caustic soda, insurance powder and penetrant should be added, especially alkali reduction treatment is important.

The author believes that the weight reduction process should be arranged after fine washing and before raising. It is beneficial to both dyeing and sanding. Therefore, it is necessaryto strictly control the amount of additives, processing time, temperature and weight reduction rate. The process parameters recommended by the author are: caustic soda 18g/L, scouring agent 6-4kg/1600-1400L, the process conditions are as follows: Equipment (overflow dyeing machine imported from Japan) ), caustic soda: 18g/L, penetrant: 4 – flame retardant cloth, cotton flame retardant cloth, nylon flame retardant cloth 6g/L, liquid volume 1400-1600 liters, liquor ratio 1︰10～15, time: 25-30min, temperature: 100-110℃, weight loss rate 14-16%. should. Fiber openingIt is appropriate for the cloth surface to be fluffy and soft, and knotting should be prevented during the production process. The heat setting process after alkali reduction treatment must be carefully and meticulously formulated. The authorrecommends the following process parameters: Equipment: LM751 type, temperature: 155-160℃, vehicle speed : 40-55/min,Time: 25~30s, falling fabric width: finished door width +3~4cm, falling fabric temperature <50℃. Sanding after shaping is the key to raising . Its typical process parameters of flame-retardant fabrics are as follows: 15-20m/min, sand leather mesh number: 280~ 400 mesh, lower pressing distance: 1-2cm, number of grinding rollers 4-5.

The author believes that: For plain weave fabrics, if the fabric surface has many interweaving points, flame-retardant cloth,100% cotton flame-retardant cloth, and nylon flame-retardant cloth do not feel smooth enough, so lightlightweight flame-retardant cloth can be used. /FONT>Grinding, the sand grain size can be higher. Twill yarn flame retardant fabric has fewer interweaving points than plain weave, so it can be reground. The dyeing after sanding should take into account the dyeing differences between polyester and flame-retardant fabrics, and select suitable disperse dyes that are close to each other in the jet or overflow dyeing machine. Medium stain. Composite additives can be used for antistatic treatment after dyeing, such as: antistatic agent 15g/L, non-ionic softener 15-20g/L, A, B, C composite rainproof agent 12:5:5:g/L process parameters are as follows: LMH722-180 type, pre-baking: 90-100℃, baking temperature: 160-170℃, speed: 25-30m/min, falling width: 144~145cm.
