Problems solved by technology

[0005] In the above-mentioned patents, the cool feeling fiber based on synthetic fiber is affected by the characteristics of synthetic fiber itself, and has the following defects in the whole life cycle of the product: petrochemical raw materials are not sustainable, and the wearing comfort of the fiber itself is lower than that of regenerated cellulose fiber. Poor, product waste non-degradable
The cooling fiber based on regenerated cellulose fiber has the disadvantages of relatively weak cooling effect and poor durability, as well as a relatively single product effect. There is a lack of composite functions with obvious functional characteristics and two or more effects on the market. type fiber

Embodiment 1

[0033] Example 1 Preparation of a cross-shaped permanent cool feeling antibacterial regenerated cellulose fiber

[0034] 1. Preparation of spinning dope

[0035] After mixing five batches of cotton pulp and bamboo pulp with a degree of polymerization of about 900 and a cellulose content of 95%, they are fully mixed with the impregnating lye, and soaked in a 238±1g / L, 50°C sodium hydroxide alkali solution for 60 minutes. Alkali cellulose is made by pressing; the alkali cellulose is crushed and aged, the aging temperature is 22°C, and the aging time is 1h; then it is mixed with CS 2 Mix for yellowing reaction, yellowing temperature is 18°C, yellowing time is 60 minutes, and the amount of carbon disulfide added to methyl cellulose is 36% during yellowing to generate cellulose xanthate; after initial dissolution of cellulose xanthate in dilute alkali solution Obtain the spinning stock solution, add 4.5% denaturing agent to methyl fiber in the later stage of dissolving, and it is ...

[0050] Example 2 Preparation of a cross-shaped permanent cool feeling antibacterial regenerated cellulose fiber

[0051] 1. Preparation of spinning dope

[0052] Five batches of wood pulp and bamboo pulp with a degree of polymerization of 1300 and a cellulose content of 98% are mixed and put into alkaline solution to make alkali cellulose, which is then crushed and aged to yellowing treatment; the yellowing temperature is 18°C , time 60min, carbon disulfide added 44% to methyl cellulose during yellowing to generate cellulose xanthate; cellulose xanthate added 4.5% denaturant to methyl cellulose in the later stage of dissolution, and its composition was 2.5% polyethylene glycol Alcohol and 2% diethylamine; the fully dissolved cellulose sulfonate is filtered through three times, defoamed and matured to obtain the spinning dope. Spinning dope index: methyl fiber: 9.89wt%, alkali content 8.53%, maturity 26ml, esterification degree 66, viscosity 95S.

Abstract

The invention provides a cross antibacterial regenerated cellulose fiber with permanent cool sense. The fiber contains jade powder particles and a herba menthae extract. The invention further providesa preparation method of the cross antibacterial regenerated cellulose fiber with the permanent cool sense. The preparation method comprises the step of spinning solution preparation, wherein viscosity of a spinning solution is higher than or equal to 60 S, and degree of esterification of the spinning solution is higher than or equal to 50. According to the prepared cross antibacterial regeneratedcellulose fiber with the permanent cool sense, pulp with higher polymerization degree and a glue making technology are selected for use, a cross section formed by the aid of a spray structure is keptvery well by primarily produced raw silk and finished fiber products under the actions of ease coagulating bath and drafting after the spinning solution with high viscosity and high polymerization degree is extruded from cross spray holes, and the fiber is endowed with better wet permeability and breathability by means of the cross structure, and therefore, the skin is endowed with lasting and permanent cool sense.

Description

technical field [0001] The invention relates to a preparation technology of a composite functional regenerated cellulose fiber, in particular to an antibacterial and antibacterial regenerated cellulose fiber with a cross-shaped cross-section, which belongs to the field of viscose fibers. Background technique [0002] Viscose fiber is an important variety of regenerated cellulose fiber. Since its industrialization in 1905, viscose fiber has entered people's lives for more than 110 years. Because viscose fiber has many advantages such as softness and comfort, moisture absorption and breathability, antistatic, bright color in the dyeing spectrum, good color fastness, and the moisture regain is most suitable for the physiological needs of the human body, it has been used among the twelve commonly used textile fiber varieties. occupies a very important position. In recent years, with the continuous deepening of the new development concept of innovation, coordination, green, open...
