6. 2. Giving to textile cloths of oil- hidrofobization
Repellane KFC is a fluorineacrilic derivative, is used from water solutions for giving of effects ole- to fibrous materials of various structure (cellulose, polyester, polyamide, woolen and mixed).
Application for polyester and polyamide fabrics:
Repellane KFC - 30-50 г/л
Processing mode: impregnation, отжим - 40 %, drying and thermal processing - 30 with at temperature 170-180 °С.
For giving of repellent effect steady a dirt (for cotton cloths) it is recommended to use Repellane in quantity to 4 % from weight of a material. Conducting: impregnation, dehydration - 70 %, drying and thermal processing at temperature 150 °С - 4 min.
6.3. Giving to fabrics of fireproof properties
Reception of fireproof and nonflammable fabrics from natural and chemical fibers, and also application of various ways of giving of fire resistance to ready fabrics of household and technical appointment is of great importance.
The materials steady against action of heats concern fire-resistant (fireproof) materials and capable to provide full or partial protection against fire. The scope of such fabrics is very wide. It is overalls a fire ных, steelmakers, founders, decorative materials for salons of courts, cars, planes and fire-prevention covers.
Pirofix used to communicate fire-proof properties and stability against multiple washings to the cellulose-containing textile materials.
Composition A preparation based on phosphorus-containing pre-baker of the thermoreactive resin. Low-dangerous substance. Mass fraction of phosphorus: 11-13 %; mass fraction of free formaldehyde: not more than1%.
Application Rules
To communicate the fire-proof properties it is recommended to add the following chemicals into the impregnation solution (g/1):
- pirofix 350-400;
- metazin 6U 60- 80
6.4. Giving to fabrics of anti-shrinkage chemical properties, form-stable finishing
Process of form-stable finishing are accompanied by following reactions (on an example of preparation based on dimethylene urea Карбамол МТ-2):
Carbamol МТ-2 - low-dangerous preparation based on dimethylene urea for the final of cellulose-containing textile fabrics with low formaldehyde content. Mass fraction of the basic substance 65 ± 3%; Mass fraction of free formaldehyde: not more than - 0,15 %.
Recommended concentrations (g/1) for the following finish processes:
- with weakly washing-off finishing agent based on thermoreactive resins (WWTR, WW) 40 - 60;
- anti-shrinkage chemical finish (ASCF) 0-120;
- schreiner-silky finish (SSF) 120 - 150;
- stable calendaring effects ( embossing, glossing) 40 - 140.
Metazin 6U - Stabilized mixture of methylol melamine Derivatives for high-quality finish of the fabrics made of cotton and artificial fibers, binder for pigment printing; for the backing of non-woven materials, carpets and floor covering. Mass fraction of the basic substance: 68-70 %; mass fraction of free formaldehyde: not more than 0,75 %. Metazin 6U - moderately dangerous substance.
Application rules
Recommended concentrations (g/1) for the following finish processes:
- with weakly washing-off finishing agent based on thermoreactive resins(WWTR, WW) 50-70;
- anti-shrinkage chemical finish (ASCF) 30-100;
- stable calendaring effects ( embossing, glossing) 80-150;
- form-stable finish of curtain-lace and knitted fabrics 50-250. Recommended concentrations of the preparation in pigment printing 100-150 g/kg.
Recommended concentrations for the backing of non-woven materials, carpets and floor covering materials 10-20 % mass.
Glikazin - mixture of methylol melamine derivatives for the final finish of cellulose-containing fabrics, binder for pigment printing, a preparation for the backing of non-woven materials, carpets and floor covering materials. Mass fraction of free formaldehyde: not more than - 0,9 %; mass fraction of the basic: substance 40 %.
Recommended concentrations (g/1) for the following finish processes:
- with weakly washing-off finishing agent based on thermoreactive resins (WWTR, WW) 50 - 70;
- anti-shrinkage finish (ASCF) 30 -100;
- stable calendaring effects (embossing, glossing) 80 -150;
- form-stable finish of curtain-lace and knitted fabrics 50 - 250. Recommended concentrations of the preparation in pigment printing 100-150 g/kg.
Recommended concentrations for the backing of non-woven materials, carpets and floor covering materials 10-20 % mass.
Carbamol GL - low-dangerous preparation based on methylolated derivative of hydroxyehtylene urea for the final finishing of cellulose-containing textile materials. Mass fraction of free formaldehyde: not more than1 %; mass fraction of the basic substance: 45 ±2 %.
