Description
Technical field
The present invention relates to textile dyeing and finishing process technology, be specially a kind of durability crease-shedding finishing agent.
Background technology
Along with human society progress, science and technology development and growth in the living standard, people wear consumption idea and the market demand there occurs marked change.From the status both at home and abroad of market fabric development and research, its emphasis mainly concentrates on comfortableness, health, the aspect such as safety and the feature of environmental protection of product.
Natural fabric comes from nature, meets the demand of people to comfortableness and environment protection health, deeply by consumers.Wherein, cotton fiber is a kind of with a long history, widely used natural fabric, is known as " green fiber " by people.Pure cotton fabric as natural fabric product, because it has soft feel, good moisture permeability, excellent wearing comfortable, and quality plentiful abundant, there is the characteristics such as better whiteness, natural environmental protection, receive the welcome of people.But COTTON FABRIC and other cellulose base fiber fabrics in use also exist poor flexibility, yielding, crease easily, wash after need the defects such as flatiron, cause cotton and other cellulose base fiber fabrics after washing and take in process and can not keep smooth outward appearance.Therefore, in order to improve cotton and the outward appearance of other cellulose base fiber fabrics in wearing process, keeping the stability of its form, improving its wearability, need to carry out anti-crease finishing in the dyeing and finishing process of textile and other cellulose fibre garment materials.
At present, crease-shedding finishing agent (or anti-crease finishing liquid) conventional in described anti-crease finishing, still based on urea aldehyde derivatives resinoid finishing agent, namely contains N-hydroxymethyl derivative structure in structure, e.g., and 2D or modification 2D resinoid etc.Fabric after this kind of resin finishing agent arranges more or less all also exists release formaldehyde problem.People usually according to crease-shedding finishing agent release formaldehyde number this resinoid is divided into low formaldehyde resin and Superlow Formaldehyde Resin.But along with the enhancing of people's environmental consciousness, awareness of safety, need safer crease-shedding finishing agent, occur formaldehyde-free anti-crease finish thus.Wherein, study more formaldehyde-free anti-crease finish and mainly contain tetrabasic carboxylic acid butane (BTCA), citric acid (CA) and tricarballylic acid (PTCA), maleic acid (MA) etc.But the N-methylol amide class finishing agent of formaldehydeless finishing agent all with traditional in reactivity, price and raw material sources etc. is mutually far short of what is expected, is therefore also difficult to replace this resinoid (as 2D or modification 2D resinoid etc.) in combination property.
Experiment shows, after modification 2D resinoid dressing liquid anti-crease finishing, strength loss that is cotton and other cellulose base fiber fabrics is very large, has had a strong impact on its wearability.Research finds, causing the powerful reason declined to mainly contain two: reason is that this kind of finishing agent defines in cotton and other cellulose fibre inside in molecule with intermolecular crosslinked, limit the mobility of cellulose macromolecule segment in cotton and other cellulose fibres, cause stress to concentrate; Another reason is that the catalyst used in conventional finish method is mostly acid or latent acidic catalyst, and acidic catalyst can cause the degraded of cellulose macromolecule chain, causes the Acid damages of cotton and other cellulose fibres.In order to improve the elastic performance of cotton and other cellulose base fiber fabrics, anti-crease finishing causes the former of powerful decrease reason inevitable; For this reason, using composite as finishing agent to dihydroxymethyl carbamide resin, excessive dihydroxymethyl triazinone and melamine methylol, add the nano-oxide with catalytic effect or cooperative effect simultaneously and make, anti-crease finishing for COTTON FABRIC is processed, while guarantee anti-wrinkle effect, improve the problem that anti-crease finishing is powerful and ABRASION RESISTANCE loss is larger in the past, fabric is without yellowing phenomenon simultaneously, has no patent or bibliographical information up to now.
Summary of the invention
For the deficiencies in the prior art, the technical problem that quasi-solution of the present invention is determined is to provide a kind of durability crease-shedding finishing agent.This anti-crease finishing liquid is a kind of nano-resin dressing liquid, using composite as finishing agent to dihydroxymethyl carbamide resin, excessive dihydroxymethyl triazinone and melamine methylol, add the nano-oxide with catalytic effect or cooperative effect simultaneously and make, anti-crease finishing for COTTON FABRIC is processed, while guarantee anti-wrinkle effect, improve the problem that anti-crease finishing is powerful and ABRASION RESISTANCE loss is larger in the past, fabric is without yellowing phenomenon simultaneously.
