Abstract
The invention relates to textiles, in particular to a process for finishing textiles of cotton goods. The invention discloses the process for finishing textiles, which comprises the steps of: 1) pretreating: cleaning the textiles, and regulating the pH value of the textiles to be faintly acid; 2) treating the textiles by using faintly acid collagen solution, wherein the weight ratio of the collagen to the textiles is 1:800 to 1:1,500; and 3) performing calendering treatment and pre-shrinking treatment. The textiles processed by the process for finishing the textile have the advantages of environmental protection and stable quality.
Description
Technical field
The present invention relates to textiles, especially the finishing technique of cotton products fabric.
Background technology
At present, the bedding on the market all are to handle with silicone softening agent.The effect of softener in textile application is the flexibility that acquisition needs.Usually can be described to: slide, be obedient to, ultra-soft, elasticity, dry and comfortable, lubricated.
The main component of silicone based softener is a grease, is flow regime at normal temperatures, so be silicone oil or amido silicon oil usually again.Amido silicon oil with interactions such as the hydroxyl of fiber surface, carboxyls, forms very firm orientation absorption with fiber because amino polarity is strong, and the coefficient of friction between the fiber is descended.This means when fabric is held in the hand, just can make with very little power to begin between the fiber to slide, so that feel soft.
The toxicity and the biological degradability that use at present more amido silicone oil microemulsion or gather emulsion softener itself can also be accepted; But form because they make emulsifying agent with the APES of 40%-50% amido silicon oil amount, its biological degradability is very poor and toxicity greatly arranged.The soft finishing agent of supply can not satisfy the ecological requirement to textile auxiliary in the market.Though many to the research of environment-friendly type softener so far, both had good biological degradability and high security, have excellent soft effect again, the product that does not influence fabric property is seldom.
At present, existing textile finishing equipment has setting machine, when doing soft treatment with organosilicon, and the speed of service 35-40 meter per second of equipment, 160 ℃ of temperature, the soak time of fabric in organosilicon: 1-2 second; After the processing, carry out press polish processing and preshrunk again and handle.
On the other hand, people have studied collagen (Collagen), are collagen again.It is that the polymer of forming various extracellular matrix is played the part of the role of conjunctive tissue in zooblast; Being the most important composition of extracellular matrix, also is the topmost constructivity protein of animal structure organization simultaneously, mainly is that the form with following insoluble fibrin exists; In the composition of human body; Account for 33% of protein, playing the part of role, can guarantee and link the structure that various tissues support human body just like ' mattress ' ' cement '.Collagen divides water-soluble and fat-soluble two kinds at present, is divided into macromolecular collagen protein and micromolecular collagen by the big I of molecular weight; And molecular weight is being low molecular collagen below 10,000.Collagen is made up of 3 amino acid helical structures.
Application facet, collagen are the Main Ingredients and Appearances of tissue, and it and each organ-tissue of human body and cell have indivisible relation, so be applied to the repairing and the regeneration of human organ tissue.The relevant medical of collagen is used and is comprised collagen protein sponge, sericterium, and (surgical hemostasis is used for cardiovascular to film, nerve; The oral cavity, orthopaedics, skin, the woman produces operation etc.) and wound dressing, artificial skin; Blood vessel, heart valve, the cornea protective material, (be used for smoothing wrinkle, soft tissue is plentiful to be filled up the injecting type collagen; The treatment urinary incontinence, urine refluxes, orthopaedics regeneration filler), medicine auxiliary mechanism, purposes such as collagen matrices template.Generally speaking, the base unit of protein is an amino acid, and its collagen is to keep one of consolidation and flexible Main Ingredients and Appearance.
Summary of the invention
The objective of the invention is to utilize collagen as finishing agent softener in other words, a kind of fabric finishing process is provided.
For realizing the foregoing invention purpose, the invention discloses following fabric finishing process: 1) pre-treatment: fabric is cleaned up, and transferring the pH value of fabric then is faintly acid; 2) handle fabric with being weakly acidic collagen solution, wherein collagen and fabric weight ratio is 1: 800 to 1: 1500; 3) carrying out press polish processing and preshrunk handles.
During cleaning, can be with alkali lye with the dirty stain of cotton seed hulls, pectic substance, grease, wax and dirt on the embryo cloth yarn, and make fiber obtain good water imbibition.Alkali lye can use 19%---24% NaOH.
Or/and after the water cleaning, need are adjusted the pH value of fabric, make fabric be faintly acid with alkali lye to remove alkali lye.Alkali is removed collagen can't be permeated, because residual alkali can influence the infiltration of collagen in pre-treatment.
The weight ratio of collagen and solvent is 1 in the preferred collagen softening agent: 600-1: 700.In general solvent is a water.The concentration of employed collagen softener is looked the cloth thickness and in this interval, is got corresponding value, and cloth is thin more rare more.
The soak time of fabric in the collagen softening agent: 2-3 second, let fabric have adequate time to absorb the water-soluble low-molecular collagen.
Preferred treatment temperature: 135 ℃-140 ℃.
By existing equipment, preferred processing speed is 30-35m/min.
By fabric finishing process provided by the invention to fabric treating after, have following characteristic.
1.--the natural tight fibers structure of----collagen makes it have obdurability and ductility to the biomethanics rerum natura, makes the lining washing resistance good;
2. owing to contain a large amount of hydrophilic radicals on the tropocollagen molecule chain, thus combines with water very capable, good permeability, absorb water and wetting capacity strong;
3. because collagen exists with triple-helix structure, make fiber have DIMENSIONAL STABILITY preferably, produce heat when colliding each other between the cellulosic, therefore be endowed hotness;
4. because collagen has tissue and framework, support and protective effect, institute is so that lining has good elasticity, and is very neat through the weft yarn cross arrangement;
5. because the characteristic of collagen own makes the lining frictional electrification press significantly decline;
6. be natural materials because of collagen, the product Environmental Safety.
The specific embodiment
Embodiment
One, pre-treatment
1, after material dyed lechery, rinsing was clean, removes the impurity on the fabric with 22%NaOH solution.
2, add softener before, the pH value must reach 5.6-5.7, can the adding citric acid pickling make its pH value reach 5.6-5.7 if the pH value can not reach this scope.
Two, pad
1, preparation before softener is handled: 1. get liquid: container disinfects in alcohol, makes stoste not contaminated; 2. water is put into cylinder, pour collagen stoste into, make concentration reach requirement, promptly collagen and water weight ratio are 1: 600 to 1: 700, measure the pH value and reach 5.5, stir under the normal temperature state.
2, detect the pH value that configures solution, the pH value will reach 5.6-5.7; Must detect the pH value, not reach requirement, add citric acid and make its pH value can reach desired standard.
The detection allotment of pH value of solution value must be before lining adds, to accomplish.
3, handle preceding equipment debugging, speed of service 32m/min, temperature: 137 ℃.
Three, soft treatment
Machine is dried directly clot of back through the processing of collagen solution on the cloth.
Four, press polish processing and preshrunk are handled.
