Problems solved by technology

[0003] Kapok fiber and crystal cotton fiber are first of all due to the large hollowness of the fiber, resulting in a very small linear density of the fiber and a very light fiber; secondly, because the kapok fiber and crystal cotton fiber do not have natural curls similar to cotton fibers, and the surface of the fiber and its The fiber is smooth, the cohesion between the fibers is too poor in fiber spinning, and the relative torsional stiffness of the fiber is greater than that of the glass fiber, which will cause the fiber twisting efficiency to decrease
Due to the short length of kapok fiber, low strength and poor cohesion between fibers, it has brought great difficulties to spinning and weaving. Therefore, it is difficult to spin alone with cotton or wool spinning. This has not been very common in the past. One reason for the good use of these fibers

Abstract

The invention relates to wook lubricating oil, a preparation method for the wook lubricating oil, and an application of the wook lubricating oil in improvement of fiber spinning performance. The wook lubricating oil comprises: a high molecular polymer, a softener, an emulsifier, an organic metal salt and an assistant agent, wherein the assistant is prepared through combination of a non-ionic surfactant and an anionic surfactant. The preparation method comprises: carrying out emulsifying and stirring for the raw materials to prepare the wook lubricating oil. The application method for improvement of the fiber spinning performance comprises: applying the wook lubricating oil on ceiba fiber or crystal cotton fiber at a temperature of 20-30 DEG C before the spinning process, then placing the treated ceiba fiber or the treated crystal cotton fiber in a room with constant temperature and constant humidity to carry out balancing for 12-48 hours; then carrying out dispersing and uniformly mixing, followed by carrying out the follow-up spinning process. The wook lubricating oil provided by the present invention has characteristics of easy washing and removal, environmental protection, simple operation of the apply method, energy saving, easy industrial production. In addition, with the wook lubricating oil provided by the present invention, the ceiba fiber or the crystal cotton fiber has better carding performance, bar forming performance and spinning performance; the spinning bottle neck of the fiber in the field of textile is overcome.

Description

technical field [0001] The invention belongs to the field of crude oil and its preparation and application, in particular to crude oil and its preparation and application in improving fiber spinning performance. Background technique [0002] Crystal cotton fiber is the trade name of croissant melon fiber. The croissant melon fiber is a natural plant fiber grown from the seeds of the croissant melon, and its main component is cellulose. Kapok fiber and crystal cotton fiber have many similar characteristics in structure. The longitudinal appearance of kapok fiber and crystal cotton fiber is cylindrical, the surface is smooth, there is almost no turning, and the luster is good. Therefore, compared with cotton fiber, kapok fiber and crystal cotton fiber appear It is softer and has better luster, but it is weaker in strength and less elastic. After SEM observation, it is found that the cross section of kapok fiber is circular or oval, the middle section is thicker, the tip is t...
