Problems solved by technology

[0003] However, the milk fiber is smooth, has low cohesion, small curl, poor resilience, and is easy to be damaged. The prepared yarn has many yarn defects, and it is difficult to prepare high-quality high-count yarn
And the cost of milk fiber is high, the use effect of single-spun yarn is not ideal, and the application field is limited. Now it is necessary to develop a low-cost, high-quality blended high-count yarn with excellent performance of milk fiber

Embodiment 1

[0077] The pretreatment of embodiment 1 milk fiber 1#

[0078] The raw milk fiber is pretreated for health preservation. 100Kg of milk fiber is mixed with 2.5Kg of antistatic agent aqueous solution. The weight ratio of antistatic agent to water is 1:15. Wrap the bag and seal it and let it stand for more than 24 hours. The temperature in the health care room is controlled at 45°C-55°C, so that the antistatic agent solution can be evenly diffused into the fiber under the action of high temperature. The antistatic agent is a silicone surface active antistatic agent. Get milk fiber 1#.

Embodiment 2

[0079] Embodiment 2 milk fiber 2#-3#, contrast the pretreatment of milk fiber D1#-D2#

[0080] The raw milk fiber was pretreated with a pretreatment method different from that of milk fiber 1#, and milk fiber 2#, milk fiber 3#, comparison milk fiber D1#, and comparison milk fiber D2# were prepared respectively, which were compared with milk fiber 1# The differences in the preprocessing methods are shown in Table 1.

[0081] Table 1

[0082]

Embodiment 3

[0083] Preparation of embodiment 3 blended yarn 1#-3#, contrast blended yarn D1#-D2#

[0084] Milk fiber 1#, milk fiber 2#, milk fiber 3#, contrast milk fiber D1#, contrast milk fiber D2# prepared in embodiment 1 and embodiment 2 are prepared blended yarns according to the same method, and blended yarns are prepared respectively Yarn 1#, blended yarn 2#, blended yarn 3#, contrast blended yarn D1#, contrast blended yarn D2#. Taking milk fiber 1# and cotton fiber to prepare blended yarn 1# as an example to illustrate the preparation method of blended yarn.

[0085]The raw material of blended yarn 1#: the weight ratio of milk fiber 1# and cotton fiber is 45:55.

[0086] The preparation method of blended yarn 1#, comprises the steps:

[0087] 1) Process the pretreated milk fiber 1# through cleaning process A, carding process A and pre-combining process A in sequence;

[0088] Cleaning process A: The weight of milk fiber 1# is 12.90kg, and the roll length is 30m; after being pro...

Abstract

The invention discloses a blended yarn, a preparation method thereof and application thereof, and belongs to the field of textiles. The preparation method of the blended yarn is a yarn blending process, pre-drawing milk fiber strips A and combed cotton strips B are sequentially subjected to a mixing step, a roving step and a spinning step to obtain the blended yarn. The pre-drawing process is carried out on the milk fiber, the weight of pre-drawing strip before mixing is stabilized, therefore, the blending ratio is uniform and stable, and the blended yarn of uniform quality is prepared. The method has the advantages of low preparation cost and high cost performance. According to the invention, a high-count blended yarn prepared by the milk fibers and cotton fibers has yarn evenness, less nep and fewer yarn defects, the blended yarn has the advantages of cashmere and has the advantages of softness and heat preservation, wet permeability and breathability, bacteria inhibition and good sanitation, and the blended yarn is an ideal choice for making home textile products and high-end clothing fabrics.

Description

technical field [0001] The application relates to a blended yarn and its preparation method and application, in particular to a blended yarn prepared from milk fiber and cotton fiber and its preparation method and application, belonging to the field of textiles. Background technique [0002] With the continuous improvement of people's consumption level and environmental awareness, high-grade wool fabrics and new cellulose fibers with environmental protection, antibacterial and deodorizing effects are more and more popular in the market. With the further deepening of scientific research and the continuous development of new fibers, many fibers with excellent properties have been applied. Among them, milk fiber is a new type of animal protein fiber that is different from natural fibers, regenerated fibers and synthetic fibers. Milk fiber has attracted much attention because of its following advantages: milk fiber has excellent food safety; natural antibacterial Functional, an...
