Abstract
The invention discloses a kind of High-flame-retardancfireproof fireproof Ventilate cloths, it is to be prepared into yarn after carrying out mix spinning according to the ratio of 7:3 by cotton fiber and heat-sensitive variable colour polyester fiber, then yarn is dried after starching in fire-retardant sizing agent, then carries out being prepared into High-flame-retardancfireproof fireproof Ventilate cloth.The present invention passes through one layer of sizing agent compound on every one thread, contain flame retardant in sizing agent, so that every one thread all has higher flame retardant property, so that the cloth of preparation has certain flame retardant property, and the cloth prepared is that yarn is first carried out fire-retardant starching then to weave, there is gap between cloth yarn obtained, there is good permeability.
Description
Technical field
The invention belongs to cloth preparation field, it is related to a kind of High-flame-retardancfireproof fireproof Ventilate cloth and its preparation process.
Background technique
In the past few years fire frequently occurs, inevasible while fire extinguishing for fire fighter to contact with fire,
And the clothing of body-worn threatens to the life of fire fighter due to combustibility with higher, existing fire-entry suit is equal
It is to be prepared by flame-proof fireproof facing material, not only heavier mass, while in order to achieve the effect that fire-retardant general clothes is all airtight, it is hindering
In combustion fabric preparation process be usually by the way that fire retardant is added in fabric starching, achieve the effect that it is fire-retardant, because of sizing agent
The gap being added between the fabric realized is blocked, and in turn results in the air-locked situation of cloth, while at different temperatures, human body
Adaptive temperature have certain limitations, existing fire-entry suit color is certain, not can display real-time the variation of temperature in environment, therefore not
It can confirm that the limiting temperature that human body is endured in environment, be easy to cause life danger.
Summary of the invention
The purpose of the present invention is to provide a kind of High-flame-retardancfireproof fireproof Ventilate cloth and its preparation processes, by every one thread
Compound one layer of sizing agent is gone up, contains flame retardant in sizing agent, so that every one thread all has higher flame retardant property, so that preparation
Cloth have certain flame retardant property, and prepare cloth be first by yarn carry out fire-retardant starching then weave, make
Cloth yarn between have gap, there is good permeability, and the direct starching of existing cloth, so that slurry is attached on
Gap is blocked between gap, so that the permeability of cloth is poor, solving existing fire-entry suit is by flame-proof fireproof facing material
It prepares, not only heavier mass, while in order to achieve the effect that fire-retardant general clothes is all airtight, in inflaming retarding fabric preparation process
Usually by the way that fire retardant is added in fabric starching, achieve the effect that it is fire-retardant because the fabric realized of the addition of sizing agent it
Between gap be blocked, in turn result in the air-locked problem of cloth.
Composite flame-retardant agent is added in polyvinyl alcohol in cloth preparation process of the invention, is formed on composite flame-retardant agent surface
One layer of uniform starching film, since molecular weight increases after being crosslinked between the polyvinyl alcohol of low polymerization degree by toluene di-isocyanate(TDI)
Greatly, so that bondability increases, the starching crystallized ability of yarn is enhanced, simultaneously because being coated in sizing agent compound
Fire retardant, so that composite flame-retardant agent is fixed on the surface of yarn after yam surface starching, so that yarn anti-flammability with higher
Can, simultaneously because sizing agent adhesive property with higher itself, can make composite flame-retardant agent be adhesively fixed in yarn
Surface, while by being coated and fixed, so that composite flame-retardant agent is coated in adhesive, directly added upper with existing fire retardant
It starches in agent, by the adhesive force stationary phase ratio of sizing agent, fixation is stronger, and disperses more evenly, will not washing due to fabric
The reduction for causing flame retardant agent content in sizing agent is washed, and then not will cause the reduction of waterproof performance；Simultaneously because composite flame-retardant agent
It can be dispersed in sizing agent, so that the fire retardancy of fabric different location is identical, prevent fire retardant dispersion from unevenly making
Cannot be fire-retardant at portion, cause the burning of the position fabric.
The present invention compound heat-sensitive variable colour polyester fiber in the yarn, so that color may be implemented in cloth at a certain temperature
Variation, and then monitor indoor temperature change in real time, it is enhanced your vigilance according to the variation of temperature, solves existing fire-entry suit color
Centainly, it not can display real-time the variation of temperature in environment, therefore not can confirm that the limiting temperature that human body is endured in environment, be easy to make
The problem of at life danger.
The present invention directly by thermosensitive chromotropic paint-modification schiff bases, is grafted on polyester fiber by chemical reaction, modified
Schiff bases is combined by chemical action and is fixed on polyester fiber, be can be uniformly distributed on polyester fiber, is passed through polyester fiber
It is evenly distributed with thermosensitive chromotropic paint on the yarn of the uniform mix spinning preparation of cotton fiber, so that camouflage paint uniformly divides
Cloth is on the cloth that complex yarn is worked out, so that the color that cloth is shown is uniform, and when temperature reaches discoloring temperature, cloth
