Problems solved by technology
The fabric prepared in this scheme has good flame-retardant and heat-insulating effects, but the combination of multi-layer structures with different functions has problems such as high cost, complex structure, high difficulty in preparation, and inconvenient use. It is more difficult and the promotion value is lower. At the same time, in the process of use, the finished fabric is obtained by combining multi-layer structures in this scheme. Due to the large number of structural layers of the fabric, it is easy to appear delamination and tearing during use. Problems that affect the normal use of fabrics

Embodiment approach
[0043] As an embodiment of the present invention, the aramid fiber 4 is a sheath-core fiber, and the core layer 1 of the aramid fiber 4 is made of aramid raw material, and the skin layer 2 is made of a polyester raw material; the aramid fiber The core layer 1 of 4 is mixed with a flame retardant 3; the skin layer 2 of the aramid fiber 4 is mixed with vermiculite; the vermiculite is evenly mixed into the raw material for preparing the skin layer 2 of the aramid fiber 4 by stirring ;
[0044] When working, during the preparation process, the vermiculite mixed into the skin layer 2 of the aramid fiber 4 can utilize the good heat insulation performance of the vermiculite to improve the flame retardancy of the aramid fiber 4. At the same time, during use, Due to the flame-retardant and heat-insulating effects of vermiculite, it can reduce the damage to the core layer 1 in the aramid fiber 4 caused by the external heat after the fabric encounters a fire, so that the flame-retardant ...
Embodiment 1
[0059] Embodiment 1: This embodiment provides a kind of blended fabric and its preparation process, and the preparation method comprises the following steps:
[0060] S1: The aramid fiber 4 is prepared by composite conjugate spinning; the flame retardant 3 is embedded in the core layer 1 of the aramid fiber 4, and the vermiculite is embedded in the skin layer 2;
[0061] S2: On the basis of the step S1, spinning the aramid fiber 4 and the metal fiber 5 to make a functional yarn 7 with a core-spun yarn structure, and then spinning the vinylon fiber to make a composite yarn 6;
[0062] S3: On the basis of the step S2, use the functional yarn 7 and the composite yarn 6 to perform blended spinning to prepare a blended yarn;
[0063] S4: On the basis of step S3, weaving with mixed yarns to obtain finished blended fabrics.
[0064] The aramid fibers are sheath-core fibers, and the core layer is made of aramid raw materials, and the skin layer is made of polyester raw materials; cer...
Embodiment 2
[0065] Embodiment 2: This embodiment provides a blended fabric and its preparation process. The preparation method is consistent with the preparation method in Embodiment 1, and only the prepared aramid fiber is changed: during the preparation process of aramid fiber, No flame retardant was added to the core layer.

Abstract
The invention belongs to the technical field of fabrics, specifically a blended fabric and its preparation process, comprising the following steps: S1: preparing aramid fiber by composite conjugate spinning; embedding flame retardant in the core layer of the aramid fiber agent, embedding vermiculite in the cortex; S2: On the basis of S1 step, spinning aramid fiber and metal fiber to make a functional yarn with core-spun yarn structure, and then spinning with vinylon fiber to make into a composite yarn; S3: on the basis of the S2 step, use the functional yarn and the composite yarn to carry out blended spinning to prepare a mixed yarn; S4: on the basis of the S3 step, use the mixed yarn to weave to obtain As for the finished blended fabric, the fabric prepared by the invention has high strength, good flame retardancy, low production difficulty and low production cost.
Description
technical field [0001] The invention belongs to the technical field of fabrics, in particular to a blended fabric and a preparation process thereof. Background technique [0002] Fabric is an indispensable daily necessities in people's life, such as widely used to make bags, tablecloths, wallpaper, curtains and bedding, etc. With the improvement of people's living standards, people are not only satisfied with the role of ordinary fabrics, but also for The strength and flame retardancy of the fabric have put forward higher requirements. [0003] There are two main ways to make functional fabrics have flame-retardant and heat-insulating properties: one is to use fibers with inherent flame-retardant and heat-insulating properties to make fabrics; the other is to modify flame-retardant and heat-insulating materials, including ordinary fibers first modified Making fabrics, or ordinary fibers are firstly made into fabrics and then modified, or both fibers and fabrics are modified...
