AI Technical Summary

Problems solved by technology

The structure of this fabric is relatively complex, the strength of the fabric is relatively small, and it does not have flame retardant properties
[0005] Adding 20% ​​high-strength vinylon to the original polyester-cotton training uniform can increase the strength of the fabric by 30%, and the wear resistance is greatly improved, but the fabric still does not have the characteristics of high strength, and the deficiency of vinylon is reflected in the lack of bright color and luster. Poor dimensional stability; improper control of tension, temperature, and time under wet heating conditions can easily cause problems such as hard hand feeling and decreased tear strength

Embodiment 1

[0047] A high-strength wear-resistant camouflage printed flame-retardant fabric, which is mainly used in the field of camouflage clothing for the army and special police, and can also be used in petrochemical, transportation, emergency rescue and disaster relief, outdoor sports and other fields.

[0048] The grammage of described high-strength camouflage printing multifunctional protective fabric is 185g / m 2, is woven from high-strength composite yarns. The high-strength composite yarn is a core-spun yarn composed of a core yarn and a sheath yarn, and its fineness is 148D.

[0049] The core yarn is made of high-strength wear-resistant filament material, namely high-strength PA66, with a strength of 85 cn / tex.

[0050] The leather yarn is outsourced staple fiber, which is composed of flame-retardant staple fiber raw materials, that is, silicon-nitrogen flame-retardant viscose fiber, aramid 1313 and high-strength flame-retardant PA6 fiber in a weight ratio of 55:30:15.

[0051...

Embodiment 2

[0062] The difference from Example 1 is that the blending ratio of the core yarn and the sheath yarn is different, which is 15:85, and the rest of the raw materials and preparation methods are the same as in Example 1.

[0063] After testing, the high-strength camouflage printed multi-functional protective fabric in this example, after the printing and dyeing camouflage process, has washing fastness, perspiration fastness, rubbing fastness and light fastness all reaching the standard of grade 4 or above, and its breaking strength The warp direction is 1032N, the weft direction is 764N, the tear strength is 126N; 98N; the afterburning time is 0S, the smoldering time is 0.1S, and the damage length is 36mm, reaching GB8965.1-2009 "Protective Clothing Flame Retardant Protection Part II Flame Retardant Clothing "Standard Class A Requirements.

Embodiment 3

[0065] The difference from Example 1 is that the blending ratio of the core yarn and the sheath yarn is different, which is 50:50, and the rest of the raw materials and preparation methods are the same as in Example 1.

[0066] After testing, the high-strength camouflage printed multi-functional protective fabric in this example, after the printing and dyeing camouflage process, has washing fastness, perspiration fastness, rubbing fastness and light fastness all reaching the standard of grade 4 or above, and its breaking strength The warp direction is 1456N, the weft direction is 1278N, the tear strength is 182N; 139N; the afterburning time is 0.5S, the smoldering time is 0.8S, and the damage length is 72mm, reaching GB8965.1-2009 "Protective Clothing Flame Retardant The second part of the protection of flame-retardant clothing "Standard Class A requirements.

Abstract

The invention provides a yarn, a fabric and a preparation method thereof. The yarn is a core-spun yarn which is compounded by a core yarn and a leather yarn in a weight ratio of 15-50:50-85, wherein the core yarn is one or a combination of high strength nylon-66 and high strength nylon-56, and the leather yarn is mainly composed of one or more of silicon nitrogen flame-retardant viscose fiber, aramid fiber and nylon-6 (preferably high strength flame retardant nylon-6). Compared with a traditional high strength wear resistant yarn, the yarn has obvious advantages in cost performance and weight,is more suitable for large-scale application, has properties of high strength, wear resistance and flame retardation, and the antibacterial and health care functions are further added.

Description

technical field [0001] The invention relates to the textile field, in particular to a yarn, a fabric and a preparation method thereof. Background technique [0002] Camouflage training uniforms can be said to be the most used type of clothing in the army. On the one hand, officers and soldiers exercise a lot during training, and the clothing is severely worn. The strength of the fabric, especially the wear resistance, has become the research team of the Military Equipment Research Institute Development focus; on the other hand, a large number of replacements makes cost control an essential factor. It is obviously not practical to use high-priced high-strength fibers to improve the wear resistance of fabrics. [0003] At this time, it is of great significance to develop a camouflage training uniform with moderate price, high strength, wear resistance, easy dyeing and camouflage printing, and flame-retardant comfort. [0004] The original camouflage clothing fabric used is po...
