摘要： The disclosure provides a method for improving the strength and dyeing of wool fibers, and belongs to the technical field of modification of textile materials. By using the feature that protein fiber macromolecules contain a large number of active groups such as hydroxyl groups, amino groups and carboxyl groups, which easily react with polyphenolic pigments formed by a phenolic compound catalyzed by an enzyme to form covalent bonding, the disclosure realizes low temperature dyeing of wool fibers while improving the fiber strength. The disclosure has mild operating conditions easy to control, and in view of increasingly emphasis on environmental protection nowadays, the use of the biological enzyme for dyeing wool fibers is safe, environmentally friendly and efficient, and has a long-term development prospect.

摘要： The invention discloses a method of dynamically configuring linear density and blending ratio of yarn by two-ingredient asynchronous/synchronous drafted, comprising: a drafting and twisting system, which includes a first stage drafting unit, a successive second stage drafting unit and an integrating and twisting unit. The first stage drafting unit includes a combination of back rollers and a middle roller. The second stage drafting unit includes a front roller and the middle roller. Blending proportion and linear densities of the two ingredients are dynamically adjusted by the first stage asynchronous drafting mechanism, and reference linear density is adjusted by the second stage synchronous drafting mechanism. The invention can not only accurately control linear density change, but also accurately control color change of the yarn. Further, the rotation rate of the middle roller is constant, ensuring a reproducibility of the patterns and colors of the yarn with a changing linear density.

摘要： The invention discloses a method of dynamically configuring linear density and blending ratio of yarn by three-ingredient asynchronous/synchronous drafted, comprising: a drafting and twisting system, which includes a first stage drafting unit, a successive second stage drafting unit and an integrating and twisting unit. The first stage drafting unit includes a combination of back rollers and a middle roller. The second stage drafting unit includes a front roller and the middle roller. Blending proportion and linear densities of three ingredients are dynamically adjusted by the first stage asynchronous drafting mechanism, and reference linear density is adjusted by the second stage synchronous drafting mechanism. The invention can not only accurately control linear density change, but also accurately control a color change of the yarn. Further, the rotation rate of the middle roller is constant, ensuring a reproducibility of the patterns and colors of the yarn with a changing linear density.

摘要： The invention discloses a method and device of dynamically configuring a linear density and a blending ratio of a yarn by five-ingredient asynchronous/synchronous drafting, comprising: a drafting and twisting system, which includes a first stage drafting unit, a successive second stage drafting unit and an integrating and twisting unit. The first stage drafting unit includes a combination of back rollers and a middle roller. The second stage drafting unit includes a front roller and the middle roller. The blending proportion and linear densities of the five ingredients are dynamically adjusted by the first stage asynchronous drafting mechanism, and the reference linear density is adjusted by the second stage synchronous drafting mechanism. The invention can not only accurately control a linear density, but also accurately control a color change of the yarn.
