Embodiment 1

[0078] 1. Using the core spinning method, the 50-micron iron-chromium-aluminum metal monofilament (that is, the metal fiber filament 12, the same below) is spun into about 60 pounds of polyester spun yarn (that is, the isolation fiber 14) through the spinning machine. ) with a twist of 400 twists / m to obtain a metal fiber composite monofilament.

[0079] 2. Use a twisting machine to twist 30 such metal fiber composite monofilaments to obtain a 30*1 composite yarn, or to obtain a 15*2 composite yarn by twisting twice; by analogy, Metal fiber composite yarn 15 with fewer single yarn cores and more strands can be obtained by twisting multiple times, see Figure 15 . Among them, in order to maintain a good dispersion effect and weaving stability, the metal fiber composite yarn is preferably twisted at 20-80 twists / m, and the twist of the initial twist can be different.

[0080] 3. Using a 5-needle flat knitting machine, weave the composite yarn into a stable structure fabric wit...

Embodiment 2

[0083] 1. Adopt the coating method, coat the water-soluble spun yarn of about 100 lbs on the 40-micron iron-chromium-aluminum metal monofilament, with a twist of 400 twists / meter, to obtain the metal fiber composite monofilament (see Figure 16-1 ).

[0084] 2. Twist 50 such composite monofilaments through a twisting machine to obtain a 50*1 composite yarn, or obtain a 25*2 composite yarn by twisting twice (see Figure 16-2 ); By analogy, metal fiber composite yarns with fewer single yarn cores and more strands can be obtained by twisting multiple times. In order to maintain a good dispersion effect and weaving stability, it is preferable to twist at 20-80 twists / meter, and the twist degree of the initial twist can be different.

[0085] 3. Use a 7-needle flat knitting machine to weave the composite yarn into a stable structure fabric with a certain thickness (see Figure 17 ).

[0086] 4. Through rolling, the thickness of the composite fabric is thinned, and part of the ya...

Embodiment 3

[0089] 1. Using a twisting machine, twist the 50-micron iron-chromium-aluminum metal monofilament and the 60-tex polyester filament with a twist degree of 200 twists / m to obtain a metal fiber composite monofilament.

[0090] 2. Through the twisting machine, twist 40 such composite monofilaments to obtain a 40*1 composite yarn, or obtain a 25*2 composite yarn by twisting twice; by analogy, you can use Multi-twisting to obtain a metal fiber composite yarn with fewer single yarn cores and more strands. In order to maintain a good dispersion effect and weaving stability, it is preferable to twist at 20-80 twists / meter, and the twist degree of the initial twist can be different.

[0091] 3. Using a 7-needle flat knitting machine, weave the composite yarn into a stable structure fabric with a certain thickness.

[0092] 4. Soak the composite fabric in concentrated sulfuric acid, partially or completely remove the insulating material components in the composite fabric, wash and dry....

Abstract

The invention provides a fabric as a combustor covering, and its making method. The fabric has a fluffy and dispersed metal fiber mesh structure and is obtained through weaving single or multiple filament metal fiber composite yarns containing an isolation material, and removing the isolation material. The fluffy characteristic of the fabric can be obtained only through the method. The fabric has the advantages possessed by a plurality of metal yarn fabrics obtained through twisting metal filaments (or bundled drawing metal fibers), has the characteristics of stable ventilation value, stable service life, and reservation of partial advantages of the cut metal fiber fabrics, and solves the key product application range restricting defects comprising bad infrared effect, easy tempering of infrared combustion of fabrics obtained through twisting the metal filaments (or the bundled drawing metal fibers) through original technologies.

Description

technical field [0001] The invention relates to a fabric, in particular to a fabric used as a burner cover (burner cover) and its semi-finished product, as well as their preparation method. Background technique [0002] As we all know, the premixed burner is easier to completely burn the fuel, and greatly reduces CO and NO X However, due to structural problems, the possibility of flashback in the premixed burner is relatively high. To prevent flashback, the design of the burner will be more complicated and bulky. Therefore, a covering for covering the surface of the housing shell to improve the aforementioned problems has been developed. see figure 1 , 2 , the outer wall 5 and the bottom surface 2 form an accommodating cavity, and the surface 3 has several holes 4 . The burner cover can be used to cover the figure 1 The surface 3 of the outer cover shell 1 of the burner shown is to increase the combustion delay space (distance) of the burner and improve the heating effi...
