Problems solved by technology

However, this method is only aimed at the anti-mite finishing of textiles, and it is necessary to add the process of anti-mite finishing of textiles in the post-processing of fibers, which not only has limited effects, but also increases the processing cost of the final product

Embodiment 1

[0021] Such as figure 1 As shown, the polyester chips are dried, melt-extruded, spun, and then drawn, first heat-set, laminated and other processes, and then oiled. The oiled working solution is formulated with Actigard AM (produced by Sanitized, Switzerland) anti-mite agent, YCD2075 (produced by Yihua Company) hollow fiber silicon-free finishing agent and penetrating agent JFC. The weight percentage of each component is: anti-mite Mite agent 50%, non-silicon finishing agent 10%, penetrating agent 3%, and the rest is water. When oiling, the working liquid is attached to the hollow fiber by impregnation on the production line; then after crimping and cutting, the second heat-setting treatment is carried out at 100-130°C for 3-10 minutes before packaging. The anti-mite hollow fiber can be obtained. After testing, the hollow fiber product contains about 1.0% anti-mite agent. Compared with the conventional hollow fiber, the hollowness, compression resilience, and smoothness of t...

Abstract

Anti-acari terylene tubular fibers are produced by adding acari expelling agent into finishing agent and penetrating agent to mix at some ratio and to obtain a stable liquid with acari expelling agent of 5 - 50%, associated with oil applying step by immersing, showering, coating, and spraying, etc. to make the said liquid onto tubular fibers, and then thermally setting. The products can have good effectiveness to expel acari and inhibit bacteria and fungi with range of >1mm, having good feeling, good bulk intensity and hollow degree without effluence to following steps. This invention does need extra apparatus and process to have advantages such as low cost, easy operation and control, flexible procedure, widely used in production of functional tubular terylene fibers with higher additional value.

Description

technical field [0001] The invention relates to a production method of polyester hollow fibers, in particular to a production method of functional polyester hollow fibers. technical background [0002] Mites are widely present in people's daily necessities such as bedding and clothing. It can spread viruses, bacteria, rickettsia, spirochetes, etc. It is a strong allergen that causes allergic asthma and causes great harm to human health. Due to the characteristics of large specific volume, good compression resilience, and good warmth retention, polyester hollow fibers are often used as wadding fibers to manufacture bedding, toys, sofas and other daily necessities. Conventional hollow fibers do not have anti-mite performance, and these daily necessities are prone to breed mites and damage human health. Therefore, whether it has the performance of anti-mite will restrict the application of polyester hollow fiber to a large extent. [0003] There are many researches and relat...
