• the manner of applying the impregnating solution to ,the textile material will depend upon the physical form of the textile being treated.

Generally, it has been found that wet pick-ups in the range of about 65 to about 100% by weight of the material being treated will give a finished, flame-retardant product having the desired resin add-on. As with the resin add-on amounts, however, it is to be appreciated that wet pickup amounts which are both greater than and less than these preferred amounts may be used to give satisfactory results in some instances, depending upon the type and weight of the fabric which is being treated.
