Abstract
The invention discloses preparation of multiple modified fibers and fiber fabrics. Active substances are reacted with the fibers and the fiber fabrics by chemical methods so that various functional groups are connected. The modified fibers and the fiber fabrics can be widely applied in the fields of daily life and health care such as filters for air purification, virus removal masks and the like.
Description
Technical field
The present invention relates to the preparation method of multiple modified fibre and sewing work.Described modified fibre and sewing work are to make active material and fiber, sewing work and the reaction of fiber activation modification thing, various functional groups in the connection by chemical method.These modified fibres and sewing work can be widely used in daily life and healthcare field such as air cleaning filter, virus removal mouth mask.
Background technology
A large amount of active groups is arranged in fiber and the sewing work, can carry out chemical modification to it at an easy rate.Previous existing cellulose connects groups such as ethoxy, carboxymethyl, ethyl and cyanoethyl by surface hydroxyl and band active group substance reaction, and product is used for coating, plastics, synthetic resin and medicine etc.Also have on cellulose, to connect carboxymethyl and diethylin, be used for the separation of biochemical substances.
Chinese patent CN101245113A discloses a kind of preparation method of hemicellulose group ion exchange resin, he prepares the hemicellulose group resin matrix with hemicellulose and polyol by cross-linking reaction, and by chemical reaction the hemicellulose group resin matrix is carried out the functionalization preparation and do fiber base ion exchange resin.
What Chinese patent CN1767862 disclosed a kind of method of removing harmful substance and this method of use removes harmful substance material and keeping method thereof, and it is with ovum gallinaceum antibody capture harmful substance.It just mentions the use fiber, and not mentioned how antibody being connected on the fiber.
Find no the people meets C4～C32 on cellulose and fabric alkyl, thiazolinyl and phenyl, also find no the people and on cellulosic fabric, connect carboxymethyl, diethylin, trimethylamine groups and imido oxalic acid.
Summary of the invention
The object of the present invention is to provide the preparation method of new modified fibre and sewing work, fiber for preparing and sewing work can be widely used in air cleaning and medicines and health protection field in the daily life.
