Embodiment

[0034] The present invention includes raw material processing, drying, POY silk manufacturing, DTY silk manufacturing, silver fiber manufacturing and graded packaging, and the specific steps are as follows:

[0035] (a) Raw material processing: Prepare the raw materials for preparing nylon yarn, including nylon 66, antioxidant, catalyst, dispersant, anti-ultraviolet additives and other additives. The raw materials are stored in the silo in advance, and they are dropped under the protection of nitrogen To the slicing silo, the raw material is sliced ​​and processed, and nano-silver ions are prepared in addition; the antioxidant chooses sulfite DLTP, the catalyst chooses sodium fluoride and sodium silicate, the ratio of sodium fluoride and sodium silicate is 2:1, and the dispersant is selected Polycaprolactone, manganese borate and aluminum silicate are selected as anti-ultraviolet additives, the ratio of manganese borate and aluminum silicate is 1:1, other additives are antistat...

Abstract

The invention discloses a production process for radiation-preventing polyamide yarns. The production process comprises the steps of raw material processing, drying, POY (pre-oriented yarn) preparation, DTY (draw texturing yarn) preparation, silver fiber preparation as well as grading and packaging. An antioxidant, an anti-electrostatic agent and an anti-ultraviolet aid are added in raw materials, so that the performance of finished polyamide fibers 66 is improved; nano-silver ions not only are attached on the surfaces of the polyamide yarns but also penetrate the polyamide yarns by utilizing a nano-silver ion vacuum high-energy-density beam electroplating technology; two fibers have good conductivity, so that a radiation-preventing effect can be achieved; nano-silver ions further have very good antibacterial performance, so that the produced polyamide yarns have antibacterial and radiation-preventing effects and are relatively good in protective capacity, breathable, washable and lasting in antibacterial and radiation-preventing performance; a production process from POY to DTY is used, so that the bulkiness and good elasticity of the polyamide yarns are kept, the compactness of filaments is enhanced, and the hand feel and comfort of a finished product are effectively improved.

Description

【Technical field】 [0001] The invention relates to the technical field of yarn processing, in particular to the technical field of the production technology of radiation-proof nylon yarn. 【Background technique】 [0002] Nylon, the scientific name of polyamide fiber, is the general name of polyamide fibers produced in China, and it is called nylon internationally. High strength, wear resistance, good resilience, can be purely spun or blended for various clothing and knitwear. The main varieties are nylon 6 and nylon 66, and their physical properties are similar. Nylon yarn is a fiber made of polyamide, divided into nylon filament and short yarn. Nylon filament can be made into elastic yarn, and short yarn can be blended with cotton and acrylic to improve its strength and elasticity. Fiber functionalization is an important direction for the development of differential fibers, and it is also the main development trend of nylon fiber spinning. [0003] The coverage of electro...
