Abstract
The present invention belongs to the textile field, and provides a method for processing a jute/cotton knitted underwear fabric. The jute/cotton knitted underwear fabric produced by the technological processes and the technological parameters disclosed by the present invention has the advantages of soft hand feeling, small strength loss and no urtication feeling, and is suitable for making intimate knitted underwear.
Description
Technical field:
The invention belongs to field of textiles, it relates to a kind of processing method of jute/cotton knitted anderwear fabric.
Background technology:
China has abundant jute resource, is third place in the world jute plantation big country.For a long time, because tossa is thick and stiff, be applied to making gunnysack and packaging material always.In recent years, because the extensive application of chemical fibre and plastic products, made the market atrophy day by day of jute traditional product.But meanwhile, crudefiber crop textiles and clothes are subjected to people's favor day by day.In bast-fibre; jute has higher moisture absorption and desorption property and initial elasticity modulus than ramie and flax; its antimildew and antibacterial ability also is stronger in bast-fibre; tossa if can be widely used in garment industry, then the rural economy, rural development and rural demography for environmental protection, sustainable development and solution country all have very big realistic meaning.Therefore, in recent years, people begin the developing focus of crudefiber crop textiles is turned to jute products cheaply gradually on the basis of successfully developing textiless such as ramie and flax.
Because the fineness of tossa is thick, length is short, and rigidity is big, shortcomings such as prodding and itching feeling obviously and pigment is heavier, seriously restricted the development of jute in the field of taking, therefore, the problem of developing jute products at present mainly concentrates on aspects such as how solving spinning property and prodding and itching feeling.
Jute belongs to the plant bast fiber.The chemical composition of jute bundle fiber mainly is the less impurity accompaniment of cellulose (60%), hemicellulose (24%), lignin (14%) and other content such as cured matter, pectin, inorganic salts, nitrogenous thing and natural colouring matter etc.Lignin in the tossa and impurity accompaniment are 5-12 times of cotton fiber than cotton fiber content height; And its filament length is the 2-5 millimeter, only is about 1/10th of cotton fiber length.At present, the become more meticulous new technology of modified technique of existing jute its objective is lignin and the impurity accompaniment removed in the tossa, improves its cellulose value, thereby improves spinning property and the wearability of fabric of jute.Although the jute bundle fiber after becoming more meticulous is being obtained certain breakthrough aspect spinning property and the woven wearability, but because fabric feeling and prodding and itching feeling problem that jute bundle fiber rigidity causes still do not obtain fine solution, the knitted underwear that exploitation wears next to the skin is still difficult.
Summary of the invention:
At the problems referred to above, the invention provides a kind of processing method of jute/cotton knitted anderwear fabric, to solve fabric feeling and prodding and itching feeling problem.
The technical scheme of technical solution problem of the present invention is as follows:
A kind of processing method of jute/cotton knitted anderwear fabric is characterized in that work flow is: the jute/cotton knitted fabric, and---------soft treatment---satinage---jute/cotton knitted anderwear fabric dyes in the chemical-biological processing;
---washing------washing------washing------washing---biology enzyme processing---washing---dehydration that oxygen floats of coming unstuck that pre-oxygen floats that the work flow that described chemical-biological is handled is: pickling
Hydrochloric acid, sulfuric acid or acetate are selected in the acid that its chemical-biological is handled in the pickling for use, and the technological parameter of pickling is acid concentration 1-2g/l, and temperature 20-50 ℃, time 20-30min, bath raio 1: 20-30; Pre-oxygen during pre-oxygen floats floats chemicals and selects hydrogen peroxide for use, and the technological parameter that pre-oxygen floats is hydrogen peroxide 10-20g/l, and temperature 80-90 ℃, time 40-60min, pH 6.5-7.5, bath raio 1: 20-30; The chemicals that comes unstuck in coming unstuck is selected NaOH and sodium sulfite or sodium phosphate or sodium metasilicate for use, the technological parameter that comes unstuck is NaOH 5-15g/l, sodium sulfite or sodium phosphate or sodium metasilicate 2-5g/l, temperature 90-110 ℃, time 60-90min, bath raio 1: 20-30; Oxygen during oxygen floats floats chemicals and selects hydrogen peroxide for use, and the technological parameter that oxygen floats is hydrogen peroxide 10-20g/l, and temperature 80-90 ℃, time 40-60min, pH 10-11, bath raio 1: 20-30; Biology enzyme during biology enzyme is handled is selected cellulase for use, hemicellulase, the commercially available complex enzyme of pectase and lignoenzyme, the technological parameter that biology enzyme is handled is commercially available complex enzyme consumption 2-3%, temperature 40-50 ℃, and time 40-60min, pH4.5-5.5, bath raio 1: 20-30.
Advantage of the present invention compared with prior art is:
1, jute/cotton knitted anderwear fabric is soft, and strength loss is little; 2, the jute/cotton knitted anderwear fabric prodding and itching feeling is eliminated fully; 3, the jute/cotton knitted anderwear fabric of the technology of the present invention processing is suitable for making the knitted underwear that wears next to the skin.
The specific embodiment:
The work flow of jute/cotton knitted anderwear fabric: jute/cotton knitted fabric---chemical-biological processing---dyeing---soft treatment---satinage---jute/cotton knitted anderwear fabric.
The jute/cotton knitted fabric that is made into, implementing chemical-biological once more handles, be in order further to remove pectin and the lignin in the jute, promote the division of tossa, improve the fineness of jute process of fiber, improve the flexibility of knit fabric and eliminate prodding and itching feeling, thus solve that tossa excessively becomes more meticulous and yarn strength between contradiction; Because knit fabric is different with woven fabric, it is gone here and there mutually to overlap to connect by coil and forms, tossa is three degree in knitted fabric crooked, make the cohesive force between the fiber obviously increase, the ability of moving of antiskid under external force strengthens greatly, so the jute/cotton knitted fabric through coming unstuck, although the further refinement of process of fiber, but still can keep the due bursting strength of underwear fabric; Through the jute/cotton knitted fabric after coming unstuck, to handle through biology enzyme again, feel improves, and the grey cloth surface smoothness is greatly improved, and prodding and itching feeling is eliminated fully, and making tossa be applied to knitted underwear becomes possibility.
