Abstract

The ordinary polyester section adds BDM-90-01 and the BD-853 through special treatment when melt spinning, anti-fluffing and anti-pilling terylene with this technology preparation, its nothing oil silk viscosity can drop to 0.43, when line density is 3.33～4.44dtex, intensity can reach 2.8CN/dtex, elongation (45～55) %, its fabric ANTIPILLING grade is 4-5 grades.
This process route can be implemented on the apparatus for melt spinning of routine and first break draft equipment.

Description

Anti-fluffing and anti-pilling terylene technology is made in the ordinary polyester section
One, the overview of " anti-fluffing and anti-pilling terylene "
Polyster fibre is a kind of good textile material, but the shortcoming of the easy balling-up of its fabric, wearability is degenerated, the anti-fluffing and anti-pilling terylene is exactly by the terylene inter-modification, the internal performance that makes it is more near wool, overcome this serious weakness of balling-up, improve the product quality and the taking of wool-like fabric, make it become one of important source material of wool-like fiber fabric gradually.
In order to reduce pilling, research indicates that the bending strength of fiber is to cause the major reason of this shortcoming, particularly polyster fibre, overcome this shortcoming itself, can only adopt the fiber and the wool top of the anti-balling-up terylene of leaveing to reduce its bending strength with regard to its raw material.
Realize this target, mainly contain two kinds of process routes, the one, low sticking route promptly adds the 3rd monomer or the 4th monomer when ester exchange (or direct esterification) polycondensation, the low sticking section of preparation copolymerization, this process route is at present both at home and abroad all in a large amount of employings; Another kind is the viscosity reduction route, promptly normal polyester section is added the 3rd component and auxiliary agent when the spinning, prepare the anti-fluffing and anti-pilling terylene, the fall of viscosity can be regulated by the addition of control the 3rd component, its spinning just can be carried out on the spinning technique equipment of routine, but also has realized suitability for industrialized production.Even to this day, we had not also met this report both at home and abroad, the realization of this process route, the really row of genus invention.
Two, Fa Ming purpose
In order to alleviate the shortage of China's wool resource, overcome the shortcoming of the easy balling-up of the fine wool-like fabric of wool-polyester blended fabric and purifying, improve the quality of products and take performance, further beautify people's clothing and the wool-like fiber raw material that develops.
Three, content of the present invention
(1) Description of content
Ordinary polyester section is added the BDM-90-01 viscosity reduction master batch of (2-4) % and 5/10000ths BD-853 when the melt spinning just can be depolymerized to high viscosity polyester and have the good low adhesive aggregation ester of fibre-forming performance, anti-fluffing and anti-pilling terylene with this technology preparation, its nothing oil silk viscosity can drop to 0.43, intensity can reach 2.8CN/dtex when line density is 3.33-4.44dtex, elongation is (45-55) %, and wool blended textile fabric ANTIPILLING grade is the 4-5 level.
