Abstract
The invention relates to a crease-resist finishing method of a fabric. The crease-resist finishing method of the fabric comprises the following steps: drying a fabric gray cloth, adding a specific amount of clear water into a reactor firstly, then adding a finishing agent, stirring continuously, adjusting the pH value to be 5-6, starting to add sizing mill liquid after complete reaction, then cross-linking, roasting, washing, softening, dewatering, adding a smoothening-softening agent, stentering for thermal forming, inspecting and packaging. The finishing agent is prepared from the following components in percentage by weight: 70%-80% of citric acid, 15%-25% of maleic anhydride and 5%-8% of nano TiO2; meanwhile, the finishing agent accounts for 20wt%-40wt% of the clear water. After being processed by the crease-resist finishing method, the cotton textile fabric is soft and smooth in hand feeling, strong in anti-shrinking and anti-creasing capability, and excellent in air permeability.
Description
Technical field
The present invention relates to a kind of facing anti-crease method for sorting.
Background technology
Because cellulose fibre has intensity and the chromatophilia of good water imbibition, hygroscopicity, feel appropriateness, so it is the main material of underwear and shirt, the natural fabric such as especially cotton, numb.But the fabric of being made by these natural fabrics has unavoidably folding line and contraction when washing.Meanwhile, the regenerated celulose fibre that 20 beginnings of the century emerged, because its wet strength is low and the contraction in when washing and fold surpass and allow limit, the folding line occurring while making to wash and shrink even more serious.For addressing this problem, for cotton knitted fabric, there is wrinkle proofing.
Wrinkle proofing, is also referred to as easy care performance, durable press finish, wrinkle resistance, wash and wear, easy-care properties etc.That is to say, after fabric washing, only need press a little or not need flatiron, have crease resistance in wearing process, nearly decades, the demand of wrinkle resistant COTTON FABRIC doubled.Cotton is a kind of cellulose fibre that is rich in hydroxyl, and wherein 4096 fiber is comprised of in crystalline region compact arranged long-chain molecule, and remaining is comprised of the long-chain molecule in amorphous region loose arrangement.Amorphous region molecule is connect by hydrogen bond and loosely is arranged, and this contributes to the pliability of fiber.When fiber is bent by External Force Acting and reverses, the molecule of amorphous region can move freely in fiber, and macromolecular hydrogen bond generation deformation or fracture cause the displacement of construction unit, thereby and in new position, forms new hydrogen bond and cause wrinkle to produce.Wrinkle finally may recover or form permanent wrinkle, and this will be depending on External Force Acting time and size.
And nonshrink, indeformable, be that cotton fiber relaxes contraction and expanded contraction in washing process.So-called mitigation is shunk and is referred to that fabric is in process, is subject to Extrude Face and makes its warp-stretch, by washing, is just returned to lentamente the phenomenon of original size.So-called expanded contraction, refers to that fiber is met water and expanded.Make yarn circumference become large, with the yarn that it slightly meets at right angles and contacts, increased the phenomenon of Len req while distorting.Relax to shrink and can with compression continuously, arrange and omit and can remove by the relaxation processes in fabric process or in final operation, but aspect the contraction that prevents the expanded generation of yarn owing to being the person's character of cellulose fibre, so be not easy to prevent.
Thus, take the production technology of shrinkproof, crease-resistant, the indeformable cotton knitted fabric as main target anxious to be resolved.
