Problems solved by technology

[0002] The medical and sanitary dressings currently on the market are generally made of ES fibers with a weight percentage of 100% as raw materials, and the thermal bonding production process is adopted. The hygroscopicity of the produced non-woven products is not high, and the water absorption is less than 700%; breathable The air permeability is not good, the air permeability is 2500-3000mm / s, the antibacterial performance is poor, the bacteriostatic rate of pneumococcus, Escherichia coli and other bacteria is not more than 60%, the hand feels hard, uncomfortable to use, and there is no natural degradation shortcoming

Embodiment 1

[0017] The processing technology of a kind of biodegradable spunlace medical nonwoven material referred to in this embodiment is to adopt the bamboo fiber that is 100% by weight as raw material, under the environment that temperature is 25-35 ℃, humidity is 75%, The raw materials are weighed and fed by the weighing feeder, and then loosened by the fiber opener; mixed in the cotton mixing box, and then half of the mixed raw materials are combed by the fiber carding machine and then enter the cross-lapper to lay the net. Enter the haul-off machine to form a cross-laid fiber web, and the other half of the raw materials are combed into a messy fiber web by an online carding machine, and then the two are laminated into a web; The needle is sprayed and strengthened many times to ensure the mechanical properties, appearance quality and style of the material, and then it is dried by a dryer, and the stain is inspected. It is a material with strong hygroscopicity and soft hand feeling,...

Embodiment 2

[0019] The processing technology of a kind of biodegradable spunlace medical non-woven material referred to in this embodiment is to adopt the chitin fiber of 3% by weight and the high-white viscose raw material of 97% by weight, at a temperature of 25- Under the environment of 35°C and humidity of 75%, the raw materials are weighed and fed through the weighing feeder, and then opened by the fiber opener; mixed in the cotton mixing box, and half of the mixed raw materials are combed through the fiber After being carded by the machine, it enters the cross-lapping machine to lay the web, and then enters the tractor to form a cross-laid fiber web. The other half of the raw materials are combed into a messy fiber web by an online carding machine, and then the two are laminated into a web; The water needles of the spunlace head in the spunlace machine are jetted and strengthened many times to ensure the mechanical properties, appearance quality and style of the material, and then dr...

Embodiment 3

[0021] The processing technology of a kind of biodegradable spunlace medical non-woven material referred to in this embodiment is to adopt the chitin fiber of 4% by weight and the high-white viscose raw material of 96% by weight, at a temperature of 25- Under the environment of 35°C and humidity of 75%, the raw materials are weighed and fed through the weighing feeder, and then opened by the fiber opener; mixed in the cotton mixing box, and half of the mixed raw materials are combed through the fiber After being carded by the machine, it enters the cross-lapping machine to lay the web, and then enters the tractor to form a cross-laid fiber web. The other half of the raw materials are combed into a messy fiber web by an online carding machine, and then the two are laminated into a web; The water needles of the spunlace head in the spunlace machine are jetted and strengthened many times to ensure the mechanical properties, appearance quality and style of the material, and then dr...

Abstract

The invention discloses a processing technique of a biodegradable medical spun-laced non-woven material, comprising the steps that: in an environment of 25 to 35 DEG C of temperature and 75 percent of moisture, the material is weighted and fed, then is opened in through a fiber opeinin machine to come into a cotton blending box to be blended; one half of the blended material is groomed by a carding machine and enters a cross lapping machine to be lapped and enters a drawing machine to form a cross lapping fiber net, and the other half of the materials is groomed by an on-line carding machine and forms a confused fiber net, and then the two halves are overlapped into a net. The netted materials are sprayed and reinforced by a plurality of times through a squirt of a spun lace head in a spun lace machine, then dried by a drying machine, and checked for stains and finally coiled by a coiler, and the whole technique is completed. The products of the technique have the advantages of strong moisture absorption, soft hand feel, excellent wearing comfort and bacteria repellancy and natural degradation.

Description

technical field [0001] The invention relates to a processing technology of a biodegradable spunlace nonwoven material for medical and health care. Background technique [0002] The medical and sanitary dressings currently on the market are generally made of ES fibers with a weight percentage of 100% as raw materials, and the thermal bonding production process is adopted.
