Description
Technical field:
The invention discloses a kind of preparation method of new modified organosilicon softener and be applied to sodolin afterIn finishing technique, belong to technical field of textile chemical engineering.
Background technology:
Sodolin belongs to native cellulose fibre, is that main linen spins raw material, have the U.S. of " fiber queen "Claim. Sodolin textile has that moisture absorption is loose wet fast, good permeability, wear the wearability such as well-pressed, simultaneously due to fibreThe self property of dimension, also has natural good wholesomeness and antibacterial and mouldproof effect, good antistatic behaviour and uvioresistantLinear energy. Advocating in the tide that dress ornament goes back to nature, these advantages make sodolin textile become people undoubtedlyThe focus of paying close attention to. But degree of crystallinity, the degree of orientation of sodolin fiber are high, large molecules align is neat, tight, causesIt extends little and poor flexibility, and this is the shortcoming of sodolin fabric maximum. Meanwhile, sodolin fabric stand variousIn processing also there are great changes in fibre morphology and fabric structure etc., causes that feel is stiff, coarse. To flaxFabric is carried out soft finish and can reduce the coefficient of friction of fiber surface, improves the frictional resistance between weft yarn,Give the lasting softness of fabric, smooth feel, improve wearing comfort. This is also improve sodolin product attachedValue added, develop one of effective way of high-grade sodolin fabric.
The main component of flax fiber is cellulose, is white in color, and also contains hemicellulose, pectin, wood except celluloseQuality, nitrogen-containing compound, adipocere matter etc., the content of the non-cellulose in fiber accounts for 30% left and right, the direct shadow of these impurityRing the physical and mechanical properties of flax fiber, and make feel coarse, color and luster jaundice. Impurity content in flax fiber is obviousHigher than cotton fiber. The soft treatment of flax has several different methods at present, comprises chemical-agent technique, softening agent and chemical modificationMethod etc. Chemical-agent technique is exactly to remove lignin as object, can lignin be generated by some chemical reactionMulti-form catabolite, part lignin is dissolved out from flax fiber raw material adding softening agent is to reduceThe chemical substance chemical modification method of fibre-fibre friction coefficient is the molecular structure that changes fiber, reduction fibre crystallinity,The degree of orientation and initial modulus, reduce lignin and pectin content, thereby improve the physical and mechanical properties of fiber, Jin ErzengAdd fibrous material flexibility. Softening agent can be divided into the reactive softening agent of nonionic, season by salt softness by its molecular structureAgent and silicone softening agent three major types. The reactive softening agent of nonionic be utilize in molecule existence-methylol or pass through-Methylol forms active group, with cellulose fibre generation chemical reaction, gives the soft effect of durability, but N-hydroxylMethyl can cause free formaldehyde to exceed standard, therefore less use. Season by salt softening agent use maximum be dialkyl group season by salt,Press salt and miaow type softening agent alkyl phthalein amido season, the above two biodegradability is poor, and miaow type softening agent easily makesFiber yellowing. At present most widely used is silicone softening agent, and its flexible smooth effect is hydrophobic due in structureThe cause that base-methyl aligns. Because organosilicon main chain silica chain has very large bond angle, be therefore connected to silicon atomOn the methyl umbrella cover that looks like to open rotate around the silicon atom connecting thereon, methyl almost can cover siloxane chain to cover,Nonpolar methyl can make interchain molecular attraction reduce, thereby makes methylsiloxane molecule twist or line cast structural,And Atomic adsorption is at fiber surface. After organosilicon flexible arranges, fabric face forms film, thereby obtains level and smoothSoft effect.
Fabrics smooth after silicone softening agent arranges is effective, obtains warm plentiful feel, can improve tearing of fabricBroken brute force and scuff resistance, and high temperature resistant, not yellowing, do not affect the advantage such as coloured light of PRINTED FABRIC, by World TextileBoundary is as the supporting softening agent of first-selection of resin finishing. Amino-modified silicone softening agent is that side chain or end group are with aminoPolysiloxanes. Amino can be uncle's ammonia, parahelium, tertiary ammonia or money salt, also can be aromatic amine. Through amino-modified siliconeThe fabric elasticity that softening agent arranges obviously improves, very firm with the combination of fiber, has good washable effect, makesIt has softness, smooth plentiful, whippy feel, greatly improves the mechanical performance of fabric simultaneously, also has oneFixed crease-resistant, shrinkproof effect. Organosilyl with aminoethyl, aminopropyl in amino-modified silicone softening agentEffect is best, but amino-modified silicone softening agent be heated or ultraviolet impact under easily yellowing, thereby should not useIn the soft finish of light fabric. Therefore for the special fibre structure of flax fiber, it is special that exploitation one has high efficiencyThe flax fiber softener of one property, significant.
