Abstract
The invention discloses a method for preparing a polyacrylonitrile fiber, and relates to the field of textile fabrics. The polyacrylonitrile fiber comprises the following components in percentage: 25-45% of methyl acrylate, 10-20% of acrylonitrile and 35-55% of methyl methacrylate. The preparation process comprises the following steps: polymerizing, drafting in steam, desizing, oiling, drafting and drying. The polyacrylonitrile fiber is good in insulating property, high in skin softening property, low in carbon, environment-friendly, good in gloss and smooth in hand feeling, and the structure and the property of the prepared primary fiber can meet the requirements on spinning machining and application.
Description
Technical field
The present invention relates to textile product field, be specifically related to a kind of preparation method of polyacrylonitrile fibre.
Background technology
Polyacrylonitrile fibre has the title of artificial wool.Have soft, bulk, be difficult for dying, bright in colour, fast light, antibacterial, be not afraid of the advantage such as damage by worms.
The current structure due to the as-spun fibre obtaining in spinning process is imperfection also, physical and mechanical properties is poor, be embodied in fiber strength very low, extend very large, boiling water shrinkage is very high, can not be directly in order to the resultant yarn of weaving, so the structure of as-spun fibre and performance can not meet the requirement of textile process and use.
Summary of the invention
The formula and the preparation technology thereof that the object of this invention is to provide polyacrylonitrile fibre, strong, the soft skin performance of its thermal property is strong, low-carbon (LC), environmental protection, reflecting feel is good, feel is submissive, and the structure of the as-spun fibre after having prepared and performance can meet the requirement of textile process and use.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: its recipe ratio is: methyl acrylate 25%～45%, acrylonitrile 10%～20%, methyl methacrylate 35%～55%; Its preparation technology is: polymerization, steam drafting, destarch, oil, stretch, dry.
Described polymerization is the tow of several spinning head ejections to be assembled to large strand of tow of a routing density with uniform tension force, is convenient to rear processing.
Described steam drafting is that large strand of tow after polymerization carried out to steam drafting by multiple roll steam drafting machine.
Described oiling is by the oil bath of tow process, at fiber surface, is covered with very film of one deck.
Described stretching is in order to make chemical fibre have the tensile property of similar natural fabric, to increase the cohesive force between fiber, for improving textile process performance, improve the taking of fabric, conventionally will carrying out stretch process to the fiber after steam drafting.
Described oven dry is generally carried out on curtain plate type or cylinder heat setter.The mode of heat setting is divided tension heat setting and relaxation heat setting.
The present invention has following beneficial effect: strong, the soft skin performance of thermal property is strong, low-carbon (LC), environmental protection, reflecting feel is good, feel is submissive, and the structure of the as-spun fibre after having prepared and performance can meet the requirement of textile process and use.
The specific embodiment
This specific embodiment is by the following technical solutions: its recipe ratio is: methyl acrylate 15%, acrylonitrile 40%, methyl methacrylate 45%; Its preparation technology is: polymerization, steam drafting, destarch, oil, stretch, dry.
Described polymerization is the tow of several spinning head ejections to be assembled to large strand of tow of a routing density with uniform tension force, is convenient to rear processing.
Described steam drafting is that large strand of tow after polymerization carried out to steam drafting by multiple roll steam drafting machine.
Described oiling is by the oil bath of tow process, at fiber surface, is covered with very film of one deck.
Described stretching is in order to make chemical fibre have the tensile property of similar natural fabric, to increase the cohesive force between fiber, for improving textile process performance, improve the taking of fabric, conventionally will carrying out stretch process to the fiber after steam drafting.
Described oven dry is generally carried out on curtain plate type or cylinder heat setter.The mode of heat setting is divided tension heat setting and relaxation heat setting.
The present invention has following beneficial effect: strong, the soft skin performance of thermal property is strong, low-carbon (LC), environmental protection, reflecting feel is good, feel is submissive, and the structure of the as-spun fibre after having prepared and performance can meet the requirement of textile process and use.
