Requirements of grey fabric for pure cotton flame-retardant fabric

2019-02-22

Durable pure cotton flame-retardant fabric is a kind of protective fabric which can make flame retardant adsorb on cotton cloth and play a flame-retardant effect. In order to ensure the flame-retardant effect of pure cotton flame-retardant fabric, the grey fabric has strict requirements.

When the grey fabric is pretreated, it will add different additives according to the different contents of the yarn sizing of the grey cloth, wash the yarn sizing thoroughly and clean the impurity contained in the fabric, so as to improve the capillary effect of the fabric, make it longer than 8 cm. The fabric dyeing effect is even when the capillary effect is uniform, and the final flame retardant effect of pure cotton flame-retardant fabric is better. If the capillary effect of fabric is not good, it will lead to less and uneven flame retardant adsorbed on the fabric in production, resulting in the final flame retardant effect is not good.

Requirements of grey fabric for pure cotton flame-retardant fabric

The moisture content of grey fabric is also required in the production of pure cotton flame retardant cloth. If the moisture content of the fabric is too high, the flame retardant effect of the fabric will be good, but the handle of the fabric will be hard, and the tearing strength will be poor; If the moisture content of the fabric is small, it will lead to poor flame-retardance, poor flame retardance in washability, soft feel of fabric and good tear strength. All above will lead to indexes of pure cotton flame-retardant cloth are not up to standard. Therefore, in production, the moisture content of grey cloth should be controlled properly. Only by controlling the moisture content of fabric, can the pure cotton flame retardant fabric have good flame retardant effect, good handle and tear strength at the same time.
