Description
Technical field
The invention belongs to textile technology field, relate to a kind of processing method of cotton stalk skin natural fabric, be specifically related to a kind of separation method of cotton stalk hide fiber.
Background technology
The research and development of fibrous material are the research topics that domestic and international relevant departments extremely pay close attention to, and to economize on resources also be one of the subject matter of international concern and research.The Chinese government advocates environmentally friendly, conservation-minded society, cotton stalk is as inevitable in cotton production process and obsolete material that is that formed, make full use of cotton stalk skin development of resources tencel, not only meet the demand of China's Development of Textile Industry, also can improve the income of cotton grower, weak point is that cotton stalk hide fiber is as process of fiber, its fiber is thick, rigidity is large, the bifurcation of fiber is serious, and the fineness discreteness along fibre length direction fiber is large, and textile process difficulty is large.
Summary of the invention
The object of this invention is to provide a kind of separation method of cotton stalk hide fiber, solve that existing cotton stalk leather is thick for native cellulose fibre, rigidity is large, the problem that textile process difficulty is large.
The technical solution adopted in the present invention is: a kind of separation method of cotton stalk hide fiber, first with water, cotton stalk hide fiber humidification is vexedly put, with roller and clearer card first time combing, then soak with sulfuric acid solution, by normal-temperature water, the cotton stalk hide fiber after sulfuric acid solution process is rinsed again, and dehydrate, finally with roller and clearer card combing again.
Feature of the present invention is also,
Wherein, humidification adds water for carrying out spraying to cotton stalk hide fiber, and the mass ratio of cotton stalk hide fiber and water is 1:1 ~ 1:5, and the vexed time of putting is 8 ~ 12h.
Wherein, the process conditions of first time combing are that cylinder-worker rollers spaces 0.5 ~ 0.9mm, and cylinder-doffer is spaced 0.4 ~ 0.7mm, cylinder-working roll speed ratio 20:1 ~ 10:1.
Wherein, the concentration of sulfuric acid solution is 10 ~ 70ml/L, and the condition of immersion is bath raio 1:30 ~ 1:50, soak time 30 ~ 150min, temperature 40 ~ 80 DEG C.
Wherein, dehydrate as by the Free water in Water Extraction Machinery de-fibering, then at 65 ~ 75 DEG C, dry 1 ~ 2h.
Wherein, then the process conditions of combing are that cylinder-worker rollers spaces 0.4 ~ 0.9mm, and cylinder-doffer is spaced 0.3 ~ 0.6mm, cylinder-working roll speed ratio 20:1 ~ 10:1.
The invention has the beneficial effects as follows: the present invention utilizes sulfuric acid solution to process cotton stalk hide fiber, make the reduction of cotton stalk hide fiber fineness, pliability raising, be of value to feel, the flexibility of improving fiber, improve the spinning performance of cotton stalk hide fiber.
Accompanying drawing explanation
Fig. 1 is the process chart that the cotton stalk hide fiber of the present invention is separated.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
A kind of separation method of cotton stalk hide fiber, as shown in Figure 1, first put cotton stalk hide fiber humidification is vexed with water, with roller and clearer card first time combing, then soak with sulfuric acid solution, by normal-temperature water, the cotton stalk hide fiber after sulfuric acid solution process is rinsed again, and dehydrate, finally again with roller and clearer card combing again.
Its concrete steps are as follows:
Step 1: humidification, is 1:1 ~ 1:5 according to the mass ratio of cotton stalk hide fiber and water, carries out spraying add water to cotton stalk hide fiber, and vexedly puts 8 ~ 12h;
Step 2: roller card, to the cotton stalk hide fiber after step 1 humidification, utilizes roller and clearer card combing 1 time, and wherein cylinder-worker rollers spaces 0.5 ~ 0.9mm, and cylinder-doffer is spaced 0.4 ~ 0.7mm, cylinder-working roll speed ratio 20:1 ~ 10:1;
Step 3: sulfuric acid solution process, soak the sulfuric acid solution of step 2 with the cotton stalk hide fiber 10 ~ 70ml/L after roller and clearer card combing, its condition is bath raio 1:30 ~ 1:50, processing time 30 ~ 150min, temperature 40 ~ 80 DEG C;
Step 4: washing: the cotton stalk hide fiber after the process of step 3 sulfuric acid solution is rinsed by normal-temperature water;
Step 5: dehydrate: slough the Free water in the cotton stalk hide fiber after washing with Water Extraction Machinery, then dry 1 ~ 2h at 65 ~ 75 DEG C;
Step 6: roller card: the cotton stalk hide fiber dehydrated step 5, with roller and clearer card combing 1 time, its cylinder-worker rollers spaces 0.4 ~ 0.9mm, and cylinder-doffer is spaced 0.3 ~ 0.6mm, cylinder-working roll speed ratio 20:1 ~ 10:1.
Cotton stalk hide fiber fineness after process of the present invention is 35 ~ 45dtex, and pliability is 1.40 ~ 1.65 sth. made by twisting/(dtexm).
From principle aspect, inventive point of the present invention is described:
Existingly come unstuck through alkali that obtained cotton stalk hide fiber is thick, rigidity is large, and there is serious bifurcation in fiber, thus cause cotton stalk hide fiber textile process difficulty, the present invention is according to the characteristic of cotton stalk hide fiber, adopt the cotton stalk hide fiber of sulfuric acid solution process, thus improve the separating degree of fiber, improve fibrous woven processing characteristics to a certain extent.One, cotton stalk hide fiber and bast-fibre similar, all containing lignin, in ramie constituent analysis, adopt sulfuric acid lignin degrading, thus determine the content of lignin in fiber.When in textile fiber, content of lignin exceedes certain value, the overall performance of fiber is deteriorated, main manifestations is that fiber is stiff, matt, feel is poor, adopt sulfuric acid solution process fiber under certain condition, the partial lignin in fiber can be removed, the pliability of fiber increases, thus improves the spinning property of fiber.Two, in the process of the cotton stalk hide fiber of sulfuric acid treatment, also been removed a part of colloid of adhesion between fiber, improve interfibrous separating degree, the fineness of fiber reduces.Before sulfuric acid solution process, the cotton stalk hide fiber of combing, makes processing procedure even action; The cotton stalk hide fiber of combing after sulfuric acid solution process, the bonding can loosened between cotton stalk hide fiber, simultaneously for the further application of cotton stalk hide fiber provides loose fiber.
