Virgin polyester staple for spunlaced nonwovens
Polyester staple fibers for spunlaced nonwovens have four characteristics:
good anti-static property, bundling cohesion, opening performance, and zero defect;
Have better hand feel, more appropriate initial modulus; Using suitable oil or takemoto hydrophilic oil, so that it has low foaming property, hard water safety, to effectively reduce the load of water circulation system, reduce process fluctuation; Can meet the hygiene, health care, food fiber safety requirements; Using reasonable process parameters, the fiber has reasonable breaking strength and elongation, to ensure that the fabric has good tearing strength, ductility.
The electrical resistance of Virgin polyester staple fiber for spunlace nonwovens is good
After the treatment of hydrophilic oil agent, the friction performance, specific resistance performance, flexibility performance, moisture absorption performance and infiltration performance of polyester staple fiber are significantly improved, especially the high hydrophilic polyester staple fiber.
Advantages of Virgin polyester staple fiber for spunlace nonwovens
The improvement of these properties is beneficial to the unwinding, carding and spunlaced processing of nonwovens in the forming process, which will improve the uniformity of fiber mesh formation and the tangling effect during spunlaced processing.
the water thorn dedicated generally hydrophilic polyester staple fiber, the fiber of anti-static performance and some improved hygroscopicity, use blended with viscose use more, the products are mainly used in sanitary materials, home wiping cloth, high-grade synthetic leather base cloth, etc. Water special high hydrophilic polyester staple fiber, the fiber hydrophilic has got obvious improvement, can replace the viscose, save raw material costs, used for high-grade sanitary materials, industrial wiping cloth, filter materials, battery diaphragm, etc.
Application of Virgin polyester staple fiber for spunlace nonwovens
They are ideal for producing roll goods for use in various end-uses such as wipes, medical, hygiene, home and industrial applications. For enhanced customer benefits, has also come out with speciality spunlace as under: for soft handle, better surface coverage and fine GSM
for improved sinking time and better wettability
The invention relates to a method for producing polyester staple fiber special for high-cleanness nonwoven spunlace, The method is characterized in that: the method comprises the following steps in sequence: melt-conveying, spinning, clustering, transversally-moving to fall into a barrel, clustering, drawing-off, curling, fixing, cutting-off, and packaging, wherein a special oil agent for fore-spinning with concentration being 0.30-0.40% is used for spinning oiling, drawing oil-immersion and drawing oil bath; and special oil agent for post-spinning with concentration being 1.5-3.0% is used for supplement oiling; wherein the special oil agent for fore-spinning contains the following components by weight: 30-50% of synthetic ester smooth agent, 10-30% of alkyl polyoxyethylene ether sulfate antistatic agent, and 25-45% of fatty alcohol polyoxyethylene ether emulsifier, wherein a sum of components is 100%; and special oil agent for post-spinning is a non-silicon antifoaming agent. The prepared polyester staple fiber special for high-cleanness nonwoven spunlace has advantages of softness, fluffiness, health and environmental protection.
