Embodiment

[0014] First synthesize high-molecular-weight polycaprolactone: the raw material is caprolactone, the catalyst is sodium silicate and tetrabutyl titanate, and the amount of sodium silicate added is 150×10 of the amount of butanediol. -6 , the amount of tetrabutyl titanate added is 400×10 of the amount of butanediol -6 . Sodium silicate, tetrabutyl titanate, flame retardant, matting agent and caprolactone are mixed into a slurry and enter the first reactor, and the stabilizer is added into the fourth reactor in the final reaction stage. The continuous polymerization process is completed through four reactors. The synthesis process of polycaprolactone:

Abstract

The invention relates to a polycaprolactone metal fiber fabric which is characterized in that polycaprolactone with high molecular weight is firstly synthesized and is then weaved into fibers with a size of 1.56-1.65detx*38 mm, then the metal fibers are selected to be blended with the polycaprolactone metal fiber, wherein the metal fibers comprise silver fiber, copper fiber, gold fiber, stainless steel fiber and the like and have the size of 1.56-2.65detx*38 mm; and the two fibers are weaved into the fabric through procedures of blowing, cotton carding, drawing, yarn spinning, dyeing and the like.

Description

technical field [0001] The invention relates to the field of fiber fabric preparation, in particular to a polycaprolactone metal fiber fabric. Background technique [0002] With the enhancement of people's awareness of environmental protection, clothing made of environmentally friendly materials is more and more popular. Among them, degradable fiber fabrics are being researched and gradually put into use. There are more and more types of degradable fiber fabrics. It involves many fields such as medicine, food, fishery, construction, sanitation, decoration, industrial processing, etc. Among the degradable polymer materials, aliphatic polyester can be synthesized by chemical process, and the breaking strength and elongation at break can be significantly improved by increasing the synthetic molecular weight. It has industrialization and industrialization prospects, and it is also the most researched. However, the degradable aliphatic polyester fiber also has its own shortcomin...
