Description
Technical field
The present invention relates to textile technology field more particularly to a kind of fibrous material processing method and fibrous material inorganic agents.
Background technique
The textile (clothes, home textile etc.) of fiber (cotton, fiber crops, viscose glue, Modal, tencel) material production has pro-skin, inhales
The excellent comfort property such as penetrable ventilated, is favored by the majority of consumers, but can generate shrink, corrugation, deformation equidimension after washing
How unstable phenomenon makes such textile dimensionally stable for a long time, and constantly meet that the majority of consumers constantly promote wants
It asks, is textile industry key subjects of interest.
With the development of the times, people are broadly divided into following five stages for the crease-resistant research of fibrous material:
1, the general shrink-proof anti-crease finishing stage: the stage is intended to make smooth cotton fabric, dimensionally stable, wrinkle resistant, principle
Are as follows: urea element and formaldehyde reaction generate low molecule condensation product, penetrate into fiberoptic fiber, then under the action of acidic catalyst, lead to
Overheating Treatment makes its resinification, deposition and crosslinking is formed in fiberoptic fiber, creasy recovery angle index is by not collated processing
150 °~160 ° of fabric, promoted after arrangement processing to 220 °~230 °, this cotton fabric also needs after washing is dried
Want slight ironing；
2, the Wash-and-wear stage: with improve improve natural fabric Wet-resilient based on, and finishing effect not because
It washs and disappears, fabric still has good wrinkle resistance after dress and washing, and fabric is not required to ironing, and drying after washing can wear
, crease recovery angle index is further promoted to 250 °~280 °；
3, the durable press finish stage: the crease-resistant level of fabric increases than the Wash-and-wear stage, and flat appearance is not
Corrugation, the more smooth stabilization of apparent size, and play the role of keeping formation of clothing and rivel setting, the stage crease recovery angle index
280 °~300 ° are reached；
4, the low-methoxyl aldehyde arrangement stage: the stage, which largely works, is concentrated mainly on the spy of the novel finishing technique of etherified resin
Rope more successfully forms new technological flow, after conventional desizing, kiering, bleaching, mercerization finish, in conjunction with adjustment of equipment
Promotion increase Liquid Ammonia Treatment, in addition by the original dry crosslinking technique padding resin solution and then baking, with padding resin
Then solution contains the wet damp crosslinking process banked up, then baked, so that ironing-free performance is basically reached 2D resin finishing level, make simultaneously
Fabric formaldehyde burst size drops to 50mg/kg or so by 300-500mg/Kg, and the arrangement of low-methoxyl aldehyde is by hemiacetal hydroxyl
Etherificate, greatly reduces the burst size of formaldehyde, and to reduce stimulation and harm to human body, but textile is in dress and washing process
In, part it is uncrosslinked or hydrolysis generate free formaldehyde can still release, endanger environmental and human health impacts；
5, the green arrangement stage: with environmental protection and the proposition of green ecological textile concept in recent years, more brand clothes
Dress enterprise has proposed: realizing global zero-emission to the year two thousand twenty textile and its processing link, this will fundamentally be limited containing first
Contact and use of the aldehydes auxiliary agent with textile, the development and application technical study without (zero) formaldehyde DP finish agent obtain quickly
Development.It is shrinkproof, anti-in fiber-like textile as the 2D resin of high burst size of methanal and the etherified 2D resin of low burst size of methanal
Wrinkle, non-ironing technical field played important function, but since there are Form aldehyde releases to be eventually prohibited from using, and formaldehydeless class is anti-
It contracts, is crease-resistant, non-ironing technology is currently mainly dimethyl dihydroxy ethylene urea (such as: holding high the Arkofx NZK of high BASF) and BTCA
(butane tetracarboxylic acid), since only there are two crosslinked groups in molecule, dosage is big and effect is poor, is unable to satisfy wash and wear and wants for the former
It asks；The latter since crosslinking condition requires accurate control PH=2-2.8, when treatment temperature be higher than 40 DEG C, PH less than 4 when, fiber exists
Can occur to degrade strongly under this condition, so that textile be made to lose wearability, along with fabric crease-resistant performance raising and
Improve, other performances of fabric, which have, largely to be declined, and the decline of fabric tear strength is mainly manifested in, with wrinkle resistance
The raising of energy is in apparent negative correlativing relation, that is, the creasy recovery angle of fabric is higher after arranging, and tearing brute force is lower, substantially
Being that creasy recovery angle is every improves 20 °, and corresponding tearing brute force retention rate will decline 7%, although BTCA is formaldehydeless crease-resistant whole
Reason agent can obtain preferable wrinkle resistance, but 300 ° be increased to after arranging from initial 150 ° of unfinished creasy recovery angle reach
It rolls boiling hot to durable, can strongly damage 50% or more, so there are many product theoretical research article, but there is no practical application valence substantially
Value, and because its price is high, strength damage is big, technique reproducing stability is poor can not industrial applications.
In addition, being handled using Functional Chemicals textile fiber material, obtaining all kinds of textiles has height attached
Value added functionality is an important directions of textile product development in recent years, such product is also deep to be favored by market, but is used
Conventional functions of textile fabrics treatment process at present, these functionality do not have lasting washing resistance performance.
