Problems solved by technology

However, due to the high strength and high modulus and poor pre-orientation of high-performance fibers, monofilament breakage and many filaments are common during fiber production, so it is difficult to weave on ordinary looms; at the same time, the high-strength fiber fabric after weaving must be processed after Finishing and washing to remove oil can restore the mechanical conductivity of high-strength fibers to the greatest extent; while the traditional washing process is rich in acid and alkali concentrations, which will damage the mechanical properties of high-strength fibers to varying degrees

Embodiment 1

[0028] A weaving treatment method for avoiding the reduction of the mechanical properties of high-strength fiber fabrics, the steps comprising:

[0029] First, double yarn; the high-strength fiber with hairiness (which can be any one of aramid, PBO, carbon fiber, ultra-high molecular weight polyethylene, and PIPD) is machine-wrapped on the coating machine, made of high-strength fiber The core wire is wrapped with water-soluble fibers (either pectin-based fibers, gum-based fibers, polyvinyl acetal fibers, or hydroxymethylcellulose fibers) to ensure water solubility. The super-position twist of the fiber is 300-900 twists, so as to produce the composite fiber;

[0030] Second, warping: hang the bobbin wound with the composite fiber on the front bobbin creel, and carry out drawing warp and section warping;

[0031] Third, winding and paralleling; the composite fiber after warping is wound onto the warp beam according to the requirements of the head portion;

[0032] Fourth, wea...

Embodiment 2

[0037] The equipment used in this embodiment is:

[0038] Coating machine 1 (Continental MP-168 fully automatic);

[0039] 1 warping machine (Huafang HF928H high-speed intelligent slitting);

[0040] Parallel machine 1 (KARL MAYER AMR type);

[0041] 1 rapier loom (Smit FAST2.0);

[0042] 1 washing and setting machine (Germany Gaulle);

[0043] The method comprises the steps of:

[0044] The first, double yarn; will have the high-strength fiber with hairiness (in the present embodiment, high-strength fiber selects the ultra-high molecular weight polyethylene of 400D for use), adopt machine-wrapping process on the coating machine, do core with high-strength fiber, wrap around ( The composite fiber is produced by single wrapping or front and back wrapping) water-soluble fiber (in this embodiment, polyvinyl alcohol fiber is selected as the water-soluble fiber), and the super-position twist of the water-soluble fiber is 300 twists to 900 twists.

[0045] Second, warping: hang...

Embodiment 3

[0051] The pure high-strength fiber fabric prepared based on the above-mentioned weaving treatment method for avoiding the reduction of the mechanical properties of the high-strength fiber fabric has superior fabric properties, and the detection results according to the physical test are as follows:

[0052]

[0053] Using the same material and the same machine to prepare the fabric according to the conventional method, according to the physical test results are as follows:

[0054]

[0055] By comparison, it is found that the breaking strength of the fabric prepared by the conventional method is 6900N; while the pure high-strength fiber fabric prepared by the method of the present invention has a breaking strength of 8900N, and the performance is improved by 29%.

[0056] In summary, this method effectively reduces the wear of high-strength fibers on loom components caused by single-filament breakage; effectively improves the passage of fibers during the weaving process;...

Abstract

The invention discloses a weaving treatment method for avoiding reduction of mechanical properties of a high-strength fiber fabric. The weaving treatment method comprises the following steps that by high-strength fibers are used as a core and wrapped with water-soluble fibers by using a compound yarn machine wrapping process to obtain high-strength composite fibers, and the high-strength compositefibers are woven into a high-strength fabric containing the water-soluble fibers on a rapier loom by using a plain weaving process; and then water treatment is conducted to completely dissolve the water-soluble fibers, and drying and winding are conducted to obtain the pure high-strength fiber fabric. According to the method, abrasion of the high-strength fibers to loom assemblies due to monofilament breakage is effectively reduced, and the trafficability of the fibers in the weaving process is effectively improved; the damage of the acid-base concentration of traditional water treatment to the mechanical properties of the high-strength fabric is effectively reduced, and the overall mechanical properties of the high-strength fiber fabric are effectively improved; and the product defects such as the hairiness rate of the cloth cover are greatly reduced, and the weaving production benefits are also improved.

Description

technical field [0001] The invention relates to the technical field of production of special high-strength bulletproof protective fabrics, in particular to a weaving treatment method for avoiding the reduction of the mechanical properties of high-strength fiber fabrics. Background technique [0002] High-strength fiber is high-strength and high-modulus fiber, which is a synthetic fiber with a strength greater than 10CN / dkex and a modulus greater than 200CN / dkex. For example, the Kevlar fiber successfully developed in the United States (called aramid-1414 in my country) is five times stronger than steel wire of the same quality. Its density is small, only 1 / 6 of steel wire, and it can also pass through microwaves. It can be used as a reinforcement material for aviation equipment. Using viscose fiber, acrylic fiber, and pitch fiber as raw materials, high-strength, high-modulus carbon fiber obtained through high-temperature carbonization and graphitization is widely used in a...
