Description

Composite spinning method
Technical Field
The invention relates to the field of spinning methods, in particular to a composite spinning method.
Background
Cotton is one of the most important raw materials in the textile industry, and depending on the spinning process, clothes of different quality are produced. The cotton clothing is made of cotton, firstly, cotton fibers are processed into cotton yarns through a spinning process, and the cotton yarns are good in fiber straightness, less in impurity formation, good in luster, even in evenness and high in strength, and are mainly used for weaving high-grade fabrics. However, when cotton yarn is dyed, the adsorption capacity to dye is limited, and the dyeing effect is not ideal. The ramie yarn has the characteristics of cool and breathable property because of being cool and like ramie.
Wood fiber is a cellulose fiber extracted from naturally growing wood. Because the wood fiber has good air permeability, natural antibacterial, bacteriostatic, mite-removing, deodorizing and ultraviolet-resistant functions, the produced cloth has less hairiness and is well paid attention to consumers. However, bamboo fiber has the disadvantages of low strength, unsatisfactory setting and the like, and pure bamboo fiber has the disadvantages of difficult spinning, low fabric strength and the like.
Flax, one of the earliest natural fibers used by human beings, is more comfortable, stiff and smooth in wearability, softer and more elegant in color tone and smoother in hand feeling compared with textiles such as ramie, hemp, apocynum venetum and the like, has excellent performances of moisture absorption, heat dissipation, health care, bacteriostasis, antifouling, antistatic and ultraviolet resistance, and is known as 'the fiber queen of natural fibers'. However, the flax fibers have a low technical count and a large difference in length, which makes the processing of the flax yarns difficult.
Disclosure of Invention
In view of the above, there is a need to provide a composite spinning method that addresses at least one of the problems mentioned above.
A composite spinning process comprising the steps of:
modifying cotton fibers, namely uniformly mixing polyallylamine, NaOH and a reaction medium to form a reaction solution, adding the cotton fibers into the reaction solution, and washing the cotton fibers to be neutral after treatment to obtain cationic cotton fibers;
flax fiber pretreatment, namely removing impurities from the flax fiber, stretching, spraying an oil agent, and warehousing for 18-24 hours;
the method comprises the following steps of (1) performing primary processing on slivers, mixing the flax fibers with the cationic cotton fibers to prepare rough slivers, combining the rough slivers, processing the combined slivers into a first sliver through a combing process, and preparing a second sliver by using wood fibers;
drawing and spinning, namely drawing the first sliver and the second sliver to form drawn sliver, and spinning the drawn sliver to obtain spun yarn.
In one embodiment, the reaction medium is n-propanolamine.
In one embodiment, the reaction temperature of the cotton fibers and the reaction solution is 55 +/-2 ℃, and the reaction time is 3.5-4.5 h.
