The method comprises steps that cotton yarn is first disposed in a polyoxyethylene octyl phenyl ether nonionic surfactant and cellulase aqueous solution for treatment, pretreated in an alkaline solution with a certain concentration, and treated by a sodium hydroxide or lithium hydroxide solution at a low temperature to prepare stiffening linnet cotton yarn. The linnet cotton yarn preparation method provided by the invention is simple for operation and suitable for large scale production; and the obtained product has excellent performances of both cotton and linen, lasting stiffness, drapability and good dyeing performance.
Description
Technical field
The present invention relates to a kind of processing method of textile material, particularly a kind of method of cotton being imitated the fiber crops processing.
Background technology
Cotton, fiber crops, silk, hair are as most important natural fiber material in people's daily life, and their various textile products are widely used in life and every field.Wherein, fiber crops, silk, hair are subject to liking of numerous people because having special performance, but silk and hair are restricted its range of application because of expensive, non-renewable and other factors.Flax fibre and cotton fiber all belong to native cellulose fibre, except having the performance similar to cotton fiber, also have the heat conduction characteristics such as wet, stiffness and drapability be good thoroughly, but the prodding and itching feeling of flax fibre in wearing process affects the snugness of fit of human body, simultaneously, flax fibre all is difficult to be equal to cotton fiber on plantation and output.In addition, current flax fibre goods only limit the use of in clothes, family and spin etc., are only suitable for making overcoat and are not suitable for making the clothes of underwear, shirt etc. and human body intimate contact such as flax fibre; And cotton fiber is used to the nearly all aspect of field of textiles, also is used for the other fields such as health care.
Cellulose is the abundantest natural reproducible material of occurring in nature, and it not only has numerous excellent properties, simultaneously, and wide material sources, convenient, cheap, the environmental protection of extraction, and renewable.People deepen continuously and carry out research to the cotton fiber modification technology, and the mercerization finish method of cotton fiber is important technology wherein.Cotton fiber is after mercerising is processed, and yarn strength and glossiness increase, and dyeability improves.Present employed mercerization finish method probably can be divided into following two kinds: the one, carry out mercerization finish under the some tension, the performances such as the yarn of this method preparation or fabric have that gloss is vivid, intensity and dyeability enhancing; Be without mercerization finish under the tension force in addition, yarn or fabric have the fluffy performance such as abundant, and it dangles, the performance such as crease-resistant thereby effectively improve.Publication number is in the Chinese invention patent " production method of natural color cotton mercerizing thread " of CN1600916, a kind of mercerization finish method of natural colorful cotton is disclosed, it selects natural color cotton after gassing frame is singed, reeled yarn is made in reeling on reeling frame, reeled yarn is placed on to carry out mercerization finish on the mercerizing range again, alkali concn in the treatment fluid is: 26～30%, the treatment fluid temperature: 18～22 ℃, the processing time: 6 minutes 30 seconds～6 minutes and 50 seconds, tension force: stretch 1～6%; And then washing: the color cotton yarn that utilizes clear water that mercerization finish is crossed cleans to neutral, washing temperature: 65～75 ℃.The method has given the color cotton yarn the good beautiful bright-coloured equivalence of color stability, gloss after processing.Select the high cotton of high-grade combing but current mercerized cotton goods only are limited to, product is only applicable to weave high-grade shirt, T-shirt, commercial socks etc., and expensive.Although cotton or fabric have a series of excellent properties behind the mercerization finish, but DIMENSIONAL STABILITY, drapability, stiffness and the wrinkle resistance of mercerized cotton yarn or COTTON FABRIC have temporary characteristics usually, it mainly is the surface that mercerization finish Hydrogen sodium oxide molybdena commonly used only acts on cotton fiber, and do not go deep into fibre structure inside, so that mercerized yarn or fabric its above performance after washing reduces rapidly or disappears.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, a kind of preparation method who makes cotton have the imitative hemp yarn line of lasting stiffness, drapability and wrinkle resistance is provided.
In order to solve the problems of the technologies described above, technical scheme of the present invention provides a kind of preparation method of imitative hemp yarn line, it is characterized in that comprising the steps:
1, under temperature was 20～80 ℃ condition, bath raio was 10～30: 1, places the aqueous solution of nonionic surface active agent and cellulase to process cotton; By mass, in the aqueous solution, the concentration of nonionic surface active agent is 0.1～50g/L, and the concentration of cellulase is 0.1～100g/L; Described nonionic surface active agent is Triton X-100;
2, behind the cleaning, drying, be 10～30: 1 in bath raio, temperature is 20～120 ℃, and mass concentration is to process 1～100 minute in the alkaline solution of 0.1～500g/L, again under 20～80 ℃ temperature conditions, mass concentration is to process 1～60 minute in the acetic acid solution of 0.1～10g/L;
3, behind the cleaning, drying, be 10～30: 1 in bath raio, temperature is-15～30 ℃, mass concentration is to process 1～100 minute in the alkaline solution of 1～10g/L, again under 20～80 ℃ temperature conditions, mass concentration is to process 1～60 minute in the acetic acid solution of 0.1～10g/L, namely obtains imitative hemp yarn line behind the cleaning, drying.
In the technical solution of the present invention, described cotton is common cotton yarn or combed cotton yarn.Its activity of described cellulase is 10000～500000CMC.Described alkaline solution is NaOH or lithium hydroxide solution.
Compared with prior art, advantage of the present invention is: owing to adopted cotton fiber is carried out pretreated method in finite concentration contains the solution of surfactant and cellulase, make the abundant swelling of cotton fiber, help alkaline solution under cryogenic conditions, to enter smoothly the crystal structure of cellulose internal-response, therefore, the imitative hemp yarn line that provides is in the natural attribute that has kept the cotton fiber environmental protection, also have lasting stiffness, drapability and wrinkle resistance, be fit to the textile garment product of the various styles of exploitation.Simultaneously, the present invention is simple for process, is fit to large-scale production.
