Problems solved by technology

However, when the high modulus fiber is used in the field of knitting loops, due to its defects in elasticity and bending stiffness, the yarn will be elongated during the knitting process, the internal tension of the yarn will increase, and when the knitting needle The hook diameter is very small, and the needle hook can easily cut off the fibers with poor folding resistance

Abstract

The invention provides an optical fiber for an incubator and a preparation method of the optical fiber. Polyformaldehyde has excellent mechanical property, and has more excellent bending resistance, fatigue resistance, self-lubricating property, dimensional stability, creep resistance and heat aging resistance after being subjected to toughening modification by polyaryletherketone; TPU (Thermoplastic Polyurethane Elastomer) has extremely-high adhesiveness so as to favorably improve oil resistance and solvent resistance of materials; an outer core layer takes fluoroacrylate as a main base material and trifluoroethyl methacrylate as an auxiliary material, so that a refractive index is guaranteed, and good bending and wear resistance is obtained; methacryloxypropyltrimethoxysilane is taken as a compatilizer of the whole system; nanosilicon dioxide is grafted with polycarbonate, polysulfone, aramid fibers and the like by a coupling action, and is uniformly distributed on the whole outer core layer. Experimental results show that the optical fiber for the incubator, which is prepared by the preparation method disclosed by the invention, has good fatigue resistance and bending resistance.

Description

technical field [0001] The invention relates to the field of textile technology, in particular to an optical fiber for an incubator and a preparation method thereof. Background technique [0002] For various reasons, when the baby comes out of the mother's womb, the jaundice value will be abnormal. This is a disease characterized by jaundice on the skin, mucous membrane and sclera caused by abnormal bilirubin metabolism. Diseases can be divided into physiological and pathological. Physiological jaundice appears 2-3 days after birth, peaks at 4-6 days, subsides at 7-10 days, and lasts longer in premature infants. Except for a slight loss of appetite, there are no other clinical symptoms. If jaundice appears 24 hours after birth and persists in 2-3 weeks, or even continues to deepen and aggravate or reappears after disappearing, or jaundice begins to appear within one to several weeks after birth, it is all pathological jaundice. [0003] Most physiological jaundice does not...
