Problems solved by technology

[0010] Chinese patent publication number CN1818170 discloses bamboo carbon polyester fiber / cross-section PTT fiber blended yarn and a manufacturing method, wherein the blending ratio of bamboo carbon polyester fiber and cross-section PTT fiber is 60-40%; the steps of the product manufacturing method are: (1) Adopt bamboo carbon polyester fiber purchased by Liaoyang Petrochemical Co., Ltd., and the single fiber linear density is 1-3D; (2) Adopt 60-40% cross-section PTT fiber and bamboo carbon polyester fiber blending, the cross The cross-section PTT fiber adopts the cross-section PTT fiber developed by Donghua University. The linear density of the single fiber is 1-3D, and finally forms a blended yarn; it mainly solves the existing fabric made of pure bamboo carbon polyester fiber, which has poor hygroscopicity. The hand feeling is not soft, the comfort function is not good, and the technical problem of the glass-like smoothness of the fabric surface is suitable for sportswear or summer clothes under the condition where the human body sweats a lot
At present, there is no report of functional PTT fibers using nano-bamboo carbon as an antibacterial agent

Abstract

The invention relates to a nanometer bamboo carbon PTT (Polytrimethylene Terephthalate) fiber and a preparation method thereof. The nanometer bamboo carbon PTT fiber comprises the following raw materials in percentage by mass: 1-10% of antibacterial slice matrices and 90-99% of PTT slices. The preparation method comprises the steps of: evenly mixing the antibacterial slice matrices and the PTT slices, and obtaining the nanometer bamboo carbon PTT fiber by a melt spinning process, wherein the spinning temperature is 260-320DEG C, the air cooling temperature is 15-25DEG C, the wind speed is 0.1-5m / sec, and the drafting speed is 1500-2000m / min. The nanometer bamboo carbon PTT fiber has the advantages of better antibacterial effect and wide application range, and is safe for the people and the environment.

Description

【Technical field】 [0001] The invention relates to the technical field of PTT fibers, in particular to a nanometer bamboo carbon PTT (polytrimethylene terephthalate) fiber and a preparation method thereof. 【Background technique】 [0002] Bamboo is an important forest resource in our country. It grows fast, can become useful in a short period of time, and has strong regeneration ability. It can be successfully afforested once, and can be felled and used sustainably. In the past, bamboo was mainly used to make agricultural tools, fuel, furniture, daily necessities, handicrafts, building materials, flooring and papermaking, etc., with low utilization value. [0003] With the development of science and technology, bamboo charcoal is fired from bamboo in China, which greatly expands its application field. Due to the special structure of bamboo charcoal, its molecular structure is hexagonal, the charcoal is dense, the proportion is large, the pores are many, and the mineral conten...
