Problems solved by technology

[0003] Above-mentioned traditional blending process is because raw material relates to natural fiber, because natural fiber can not bear high temperature, therefore those skilled in the art generally think that can not use the blending method of melt spinning, and the production efficiency of the yarn that above-mentioned traditional blending process makes and The texture is not as good as the yarn made by melt spinning, and in the blending process of natural fiber and chemical fiber, because the natural fiber is not resistant to high temperature, the process of melt spinning still cannot be used

preparation example Construction

[0013] The invention provides a kind of preparation technology of blended polymer fiber, comprises the following steps:

[0014] Step 1: Wrap the surface of the natural fiber with a silicone resin coating and dry it;

[0015] Step 2: Melt the chemical fiber at 200-300°C, mix the natural fiber coated with silicone resin with the molten chemical fiber, and extrude to obtain a blend product of natural fiber and chemical fiber;

[0016] Step 3: washing the blended product obtained in step 2 with water to remove the silicone resin coating wrapped on the surface of the natural fiber to obtain a polymer fiber.

[0017] In the preparation process of the above-mentioned blended polymer fiber, the natural fiber is pretreated, and the surface of the natural fiber is wrapped with a silicone resin coating to make it able to withstand the high temperature of melt spinning, and then the natural fiber wrapped with the silicone resin coating is mixed with Polymer fibers are prepared from chem...

Abstract

The invention relates to the technical field of textile, in particular to the preparation technology of polymer blend fibers. The technology comprises steps of wrapping the surfaces of the natural fibers with silicon resin coatings so as to allow the natural fibers to be capable of bearing high temperature of melt spinning; and allowing the natural fibers wrapped with the resin coatings and chemical fibers under the high-temperature molten condition to be subjected to melt spinning to prepare the polymer fibers. According to the invention, by wrapping the natural fibers with silicon resin coatings, the defect that natural fibers in the prior art fail to bear the high temperature of melt spinning technology is overcome; compared with the traditional natural fiber blending technology, the spinning efficiency and yarn intensity are greatly improved; the prepared polymer fibers touch well like natural fibers and have advantages of absorbing sweat absorption, quickly getting dry and being light like chemical fibers.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a preparation process of blended polymer fibers. Background technique [0002] At present, the traditional natural fiber blending method to make yarn mainly includes the following two types; the first is to mix different fibers together through the process of carding and twisting, which is the so-called "intimate mixing"; The different yarns are twisted together to create a blended yarn, which is called a "composite" or "spun-twisted" yarn. Application publication number is that the Chinese patent of CN107675315A discloses a kind of spinning process of wrapping feather blended yarn, has just adopted the process of above-mentioned spinning twist. [0003] Above-mentioned traditional blending process is because raw material relates to natural fiber, because natural fiber can not bear high temperature, therefore those skilled in the art generally think that can not use the blendin...
