Description
Technical field
The invention belongs to Textile Engineering field more particularly to a kind of preparation methods of flame retardant type flocking yarn.
Background technique
Flocking is using charge identical charges repel each other the principle that there is a natural attraction between the sexes, so that negative electrical charge on staple fiber villus band, by flocking
Material is placed under zero potential or grounding requirement, and villus accelerates vertically to fly to flocked material surface under the action of electric field, due to planting
Down material is pre-coated with the reason of binder, and villus is just vertically adhered on material, is dried or dried in the air after flocking
It is dry to obtain finished product.In flocking field, flocked material is usually cloth, in the entirely process of production implanted article, cloth warp
The processes such as pretreatment, gluing, flocking and bristle are crossed, a large amount of villus, glue and pretreatment fluid are consumed, production is caused and plants
The rising of flannelette material cost, in order to save cost, can choose yarn is that raw material produces flocking yarn, is finally woven into cloth.And
And need to carry out degumming process in the gluing treatment process before flocking, it is therefore an objective to remove extra glue to keep certain glue
Thickness of feed layer will cause holiday or thick the phenomenon that applying, seriously affect flocking quality, need rationally to control sizing material if degumming is improper
Thickness degree can take spraying technology to control the thickness of dope layer and realize above-mentioned purpose.In addition, mentioning with living standard
Height, demand of the people to properties of textile are not limited to the performances such as decorative appearance, wear-resisting, stretching, need under certain special occasions
Want textile fabric that there are the performances such as sterilization, hydrophobic, conductive, fire-retardant, uvioresistant.In field of textiles, nano material has spy
Different uvioresistant absorbs visible light and infrared ray, anti-aging, high-intensitive and toughness, good conductive and electrostatic screening effect,
Stronger antibacterial and deodorizing function and adsorption capacity etc., therefore, by nano material and flocking with these specific functions
Fabric or yarn progress are compound, can prepare fabric and new textile material with various functions.Such as nano-aluminum hydroxide is
Good inorganic anti-flaming material, because it can be decomposited chemical bonding water (about 34.6%) at high temperature, this decomposition reaction is heat absorption
Reaction, thus the thermal degradation speed of high polymer can be delayed, slow down or inhibit the burning of high polymer, inhibits the temperature rise of high polymer, and
Promote charing and suppression cigarette.And the surface-active of nano-aluminum hydroxide is more much higher than micron-sized, improves chemical reaction speed
Rate, so that decomposition reaction is easier to carry out.Nano-aluminum hydroxide can be used as flame retardant and be added in other flame-retardant compositions, rise
To preferable flame retardant effect.
