Description
Technical field
The present invention relates to a kind of island-in-sea type composite fiber and preparation method thereof.
Background technology
Islands-in-sea type fibre has indefinite Dao Heding island composite fibre two kinds, and current indefinite island composite fibre commonly uses polyamide section and polyethylene melting blending, forms indefinite island composite fibre, then under certain condition, by sea component organic solvent extraction, forms island phase.Because island only has single component polyamide mutually, performance is single, and polyamide backbone structure and composition are simple, and only contain carboxyl and amino at molecule chain end, unprotected side chain, thus the dyeing of polyamide fiber is deeply not irregular, and Color is poor, and sanitation performance is bad.Compared with having the collagenous fibres of different side-chain structure, its performance differs greatly, and collagen is typical polyampholyte, and natural leather is the space network woven by collagenous fiber bundle.
Superfine fiber chemical leather take superfine polyamide fiber as matrix, polyurethane forms for elastomer composite, for making comfortable, health and the excellent high artificial leather microfiber synthetic leather of tinctorial property, mainly chemistry or physical modification are carried out, to increase its active group to superfine fibre or super fine base cloth at present.With the super fine base cloth of 15% sulfur acid pretreatment, polyamide fiber is hydrolyzed, then with collagen-modified, dye-uptake and COLOR FASTNESS can be increased (see " functional material " 2014,45) sanitation performance (patent CN201310647565.4) of superfine fiber chemical leather, is improved.But this method is owing to being process super fine base cloth, the consumption of acid is large, intensity is high, operation easier is large, the difficult control of degree for the treatment of, technique is loaded down with trivial details, and a large amount of high-concentration waste acid solutions and the useless treatment fluid containing crosslinking agent in production process, can be produced, especially the retention of collagen is low, and the collagen content in modified fibre is little, wayward; And spread multiple with pre-processed collagenous fiber network and island superfluorescent fiber, the Ji Bu with three-dimensional structure is made again through highly dense water thorn, also the performance (CN201310748154.4) such as ventilative of base cloth can be improved, and the utilization rate of collagenous fibres is high, content is controlled, but the weak point of this method is, must previously prepared collagenous fiber network, the not only skewness of collagenous fibres in base cloth, and collagenous fibres and islands-in-sea type fibre also just simple physical doping.
Summary of the invention
Single for existing island-in-sea type composite fiber island phase component, stock-dye weak effect, sanitation performance are bad, and the existing performance for improving islands-in-sea type fibre, and the deficiency existing for processing method before and after the base molding with cloth adopted.The invention provides a kind of novel island-in-sea type composite fiber, namely collagen is utilized directly to carry out modification to the fiber before super fine leather base molding with cloth, the island of island-in-sea type composite fiber is made to have the characteristic of collagen and polyamide two kinds of components mutually, combine the respective advantage of bi-component, thus the production being conducive to super fine leather adopts dry/wet dyeing and finishing process technology of leather, simplify the production process of high imitation leather, its performance is removed from office closer to natural leather.
