How to repair flame retardant fabrics when they are defective?
1, the treatment of oil pollution. Because high count yarns are fine and non-wear-resistant, the traditional method of scraping oil stains on flame retardant fabrics with tools can no longer be used. The new oil removers can be applied directly to the oil stains.
2. For slub treatment, low-count and low-density fabrics with tweezers to pick up the slub, the excess flame-retardant fabric fiber stripped, and then with iron comb to scrape the raised yarn flat. But the yarn of high-count flame retardant fabrics is fine, the length of fiber is long and the number of fiber roots is small. When the yarn is broken slightly carelessly, the bad effect of weft breaking and warp breaking will be very bad. When the slubby is treated, the slubby can be replaced with normal yarn, and then the slubby can be replaced by hand. The tip of the finger is leveled in the changed place.
3. Handle the transverse gear. High and low density flame retardant fabrics have low strength, so traditional methods are used to scrape and comb fancy and scratch fabrics to form scratch defects. In order to avoid damage to the bottom of the cloth, the comb can be polished and smoothed before scraping. A wet cloth is placed on the mat to enhance the strength of the flame retardant fabric, and then gently combed and slowly scraped. After pushing the warp into thin and dense places, the area scraped along the weft is leveled.
4, the treatment of neps. When there are more neps in grey cloth of flame retardant fabric, the single layer of grey cloth of flame retardant fabric can be placed on the desktop, the neps can be carefully clamped down with tweezers, and the neps can be glued away with adhesive tape. The neps must be levelled with the finger tips when the neps are not smooth.
