Description
Technical field
The present invention relates to the after-finishing of textile products technical field; Belong to the finishing agent made from natural polymer and derivative thereof, particularly finishing agent and the finishing technique of textiles being put in order with polysaccharide compound thereof.
Background technology
Cashmere mainly refers to goat cashmere, and it is as a kind of natural fabric, and is soft, quality is strong, high resilience, and gloss is soft naturally, has good hygroscopicity, warmth retention property, crease-resistant and soil resistance, is called as " the soft gold " of wool.It is fit to various high-grade underwears and coat, is subjected to liking of consumers in general deeply.But it also has a lot of unsatisfactory places, such as easy shrink, and easy breed bacteria, easy uneven dyeing etc.At present, people seek variety of way the shortcoming of wool are improved, and wherein shitosan has caused that as the finishing agent of green non-pollution people pay close attention to widely and study.
Shitosan [(1; 4) one 2 one amidos, one 2 one deoxidations, one β-D glucan] be chitin [(1; 4) one 2 one acetamidos, one 2 one deoxidations, one β-D glucan] slough the natural biological polysaccharide polymer that acetyl group wherein is prepared from through the concentrated base processing; also be the unique natural alkaline polysaccharide of finding up to now, have characteristics such as avirulence, biodegradable, excellent biological compatibility.Have a large amount of amino and hydroxyl in the chitosan molecule, have the fine solubility energy, and reactivity being strong, is a kind of natural, ecological fabric antibacterial finishing agent.
Show that according to the study the bacteriostasis of shitosan has two kinds of mechanism, a kind of is that shitosan passes through positive charge-NH
3 +The cell membrane of adsoption band negative electrical charge, make shitosan be adsorbed on surface of cell membrane and form one deck polymeric membrane, changed the selection permeability of cell membrane, stop nutriment to cause cytoplasm to run off to intracellular transportation, cell plasmolysis, thus play the restraining and sterilizing bacteria effect; Another kind of mechanism is that shitosan advances in the cell body by infiltration, has anionic cytoplasm in the adherent cell body, and the normal physiological activity of flocculation upset cell takes place, thus kill bacteria.
The chitosan anti-bacteria of textiles processing is at present mainly studied application from two aspects, is to utilize the shitosan fibre forming property on the one hand, spins out fiber, makes the persistent high efficiency antibiotic fabric.Utilize its dissolubility in diluted acid and its reactivity on the other hand, adopt to soak-roll-bake finishing technique to fabric post-treatment, to give the antibacterial fabric performance.Finishing method mainly contains, 1. coating: a certain amount of resin solution is added in an amount of chitosan solution, adjust viscosity, make it reach required viscosity requirement, in standing and defoaming; To dispose the liquid homogeneous then and be coated on the fabric, form antibiotic coated textiles.2. dipping/padding method: (1) directly uses the shitosan of high molecular, its treatment process: shitosan is dissolved in organic acid, and handles after the dilution by a certain percentage.Though this method technology is simple, influence fabric feeling (2) and adopt low-molecular-weight degradation of chitosan liquid fabric to be carried out the back arrangement by padding method, make shitosan be attached to fabric face, give the antibacterial fabric deodorizing function.Though this method solves feel problem, poor durability.
Shitosan is a macromolecular compound, if depend merely on shitosan fleece fabrics is handled, and shitosan just leans on intermolecular force (as Fan Dehuali, hydrogen bond) attached to the fleece fabrics surface, therefore, lacks water-wash resistance.How the set casing glycan is to produce durable antibiotic property, is a research focus.
At present, the research of relevant wool chitosan antibacterial finishing, mainly contain 1) antibiotic finish (Lu Na of worsted, DengBing Yao etc., the chitosan antibacterial finishing of worsted, wool spinning science and technology, 2006 the 5th phases, p10～12), high molecular (molecular weight: shitosan 500,000 g/mol), and study as crosslinking agent by citric acid has directly been used in this research; This method is owing to use citric acid, can make the fabric yellowing, and final feel can be affected 2) chitin modified research (Chen Jianyong, chitin modified and with the research of its arrangement antibacterial textile performance, the functional polymer journal, in June, 2002,15 volumes, p194～198), this research has been carried out antibacterial research 3 by modification of chitosan such as preparation methylol shitosan and ethoxy ether shitosans to fabric) viscosity flow of shitosan is to the research (Liang Liefeng of fabric set, Weng Jie etc., the research of the viscosity flow of shitosan and fabric face set, textile technology progress, 2005 the 6th phases, p14～16), this research thinks that the viscosity flow of shitosan directly influences infiltration and the set to fabric.
Summary of the invention
The present invention is intended to, and at first utilizes low-molecular weight chitoglycan that the cashmere textiles is carried out antibiotic finish, makes under its prerequisite that does not influence fabric feeling, reaches antibacterial effect; Secondly, by using crosslinking agent and alkali curing process that fleece fabrics is carried out durable finish.Have in the major technique,
