Description

Flame-retardant fireproof base fabric

Technical Field

The utility model relates to the technical field of fabric, especially a fire-retardant fire prevention backer surface fabric.

Background

Along with the enhancement of safety consciousness of people, the requirement of people on the flame retardance of household products is higher and higher, a coating method is generally adopted for household fabrics in the market at present, and a layer of flame retardant material is mainly coated on the reverse side of the fabric, so that the flame retardant effect is achieved, but the fabric becomes stiff in touch after being coated by the method, the comfort is seriously reduced, the appearance is attractive, and the flame retardant material can age and fall off gradually and lose the flame retardant function along with the increase of the washing times.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems, the utility model provides a flame-retardant fireproof base fabric.

The utility model provides a technical scheme that its technical problem adopted is: the flame-retardant fireproof base fabric comprises warp yarns and weft yarns, and is formed by weaving the warp yarns and the weft yarns in a mutually sinking and floating and staggered manner, and is characterized in that: the four warp yarns of the smallest twill weave unit are in a structure of three over one under the overlapping position with each weft yarn, and the four warp yarns of the smallest twill weave unit are in a structure of three over one under the overlapping position with each weft yarn, wherein the warp yarn over the overlapping position is a warp weave point;

the superposition points of a first row of warp yarns and first, third and fourth rows of weft yarns of the minimum twill weave unit are warp structure points, the superposition points of a second row of warp yarns and first, second and fourth rows of weft yarns of the minimum twill weave unit are warp structure points, the superposition points of a third row of warp yarns and first, second and third rows of weft yarns of the minimum twill weave unit are warp structure points, and the superposition points of a fourth row of warp yarns and second, third and fourth rows of weft yarns of the minimum twill weave unit are warp structure points;

the warp and weft of the flame-retardant fireproof base fabric are both 30S/2 double-strand flame-retardant acrylic/cotton blended yarns, the warp density of the flame-retardant fireproof base fabric is 50 pieces/inch, and the weft density of the flame-retardant fireproof base fabric is 47 pieces/inch.

The utility model has the advantages that: the warp and weft of the fabric are both made of 30S/2 double-strand flame-retardant acrylic/cotton blended yarns, and are woven on an air jet loom in 3/1 twill weave, and the whole fabric is woven by adopting permanent flame-retardant yarns, so that the fabric has strong flame retardance, the flame retardant coefficient reaches 32, the fabric can be detected by British standard BS5852, the fabric can be directly used in a composite manner without any after-treatment, and the flame retardance is guaranteed under the condition of not contacting any chemical reagent;

the fireproof fabric woven by the fabric through the raw materials can prevent the flame resistance from being reduced due to the increase of the washing times, and meanwhile, the touch feeling of the fabric is not changed, so that the attractiveness is greatly improved.
