Definitions

  • the present invention relates to a process for producing fibrous webs, fibrillar fibers or nonwoven fabrics using woven fabrics, and the fibrous webs, fibrillated fibers or nonwovens, in particular so produced And fibrillated fibers or nonwovens for hemostatic or anti-adhesion use.
  • Nonwoven fabric refers to a textile product made by tangling various fibers according to mutual properties without going through a process such as twisting, weaving and knitting to form a sheet-like web and combining them by mechanical and physical methods.
  • Nonwoven fabric manufacturing process is generally composed of three steps, such as web formation ⁇ web bonding ⁇ processing.
  • the web forming process is a process of dispersing and laminating fibers to a uniform thickness as possible on a conveyor to form a web.
  • the web bonding process is a process of tangling or gluing the fiber aggregates to give the web a moderate strength so that the fibers do not separate to form stability.
  • the processing process is a process of completing a nonwoven fabric by dyeing or processing required for the end use.
  • Nonwovens are classified into a wet method and a dry method according to the web formation method. Dry and wet are divided into whether the web is formed in a dry state or a wet state. That is, in the dry method, the fibers are formed in a web state in the air, and the wet method disperses the fibers in a liquid to obtain a web. Therefore, the web forming method is distinguished according to the matrix in which the fibers are dispersed, that is, air and liquid.
  • the nonwoven fabric is divided into a long fiber nonwoven fabric and a short fiber nonwoven fabric according to the type of fiber.
  • Oxidized Regenerated Cellulose is a known absorbent hemostatic substance. Many methods are known for forming various types of hemostatic agents based on Oxidized Cellulose (OC) into powders, fabrics, nonwovens, knitted fabrics, other forms and combinations thereof. Currently used hemostatic wound dressings include knitted or nonwoven fabrics comprising oxidized regenerated cellulose (ORC).
  • Korean Patent Laid-Open Publication No. 2013-0101109 discloses a step of providing a cellulose yarn having filaments of minimum twist; b) forming a multi-yarn, single feed circular knitted cellulose fabric with minimal twist; c) scouring the cellulose cloth; d) oxidizing the scoured fabric; e) pliabilizing the oxidized fabric; f) de-knitting the flexible fabric to form a continuous strand of crimp from about 2.0 crimps / cm (5 crimps / inch) to about 4.7 crimps / cm (12 crimps / inch).
  • the method includes the step of softening the oxidized fabric and then de-knitting it and cutting it to form a staple fiber of a certain length, which results in a long and complicated manufacturing process.
  • a fibrillated fiber or nonwoven fabric usable for phase fibers or nonwovens, in particular for hemostatic or anti-adhesion applications.
  • a method of making a fibrous web comprising carding a woven fabric.
  • a method for producing fibrillated fibers comprising calendering a fibrous web produced according to the above method.
  • a fibrous web, fibrillated fibers and a nonwoven fabric each produced by the above method.
  • the present invention by applying the woven fabric, not short fibers or long fibers directly to the carding process, there is an advantage that can simplify the manufacturing process of the fibrous web, fibrillated fibers or nonwoven fabric.
  • the term "fabric” is a concept including a knit.
  • the woven fabric used for the production of fibrous webs, fibrillated fibers or nonwovens is not short or long fibers.
  • the fabric may be Oxidized Regenerated Cellulose (ORC), Oxidized Cellulose (OC) or a combination thereof.
  • ORC Oxidized Regenerated Cellulose
  • OC Oxidized Cellulose
  • oxidized (regenerated) cellulose means oxidized (regenerated) cellulose having a carboxyl group (-COOH).
  • the carboxyl group content (ie degree of oxidation) in the oxidized (regenerated) cellulose may be 13-24% by weight.
  • the oxidized (regenerated) cellulose having an oxidation degree of 13 to 17% by weight is preferable in terms of enhancing the anti-adhesion effect, and the oxidation degree is more than 17% to 24% by weight, for example Oxidized (regenerated) cellulose, which is 18 to 24% by weight, is preferred in terms of enhancing the hemostatic effect.
  • Oxidized (regenerated) cellulose can be prepared according to methods known in the art, for example, US Pat. No. 7,279,177, US Pat. No. 3,364,200, US Pat. No. 5,180,398, US Pat. No. 5,134,229, US Pat. It may be prepared according to the method disclosed in US Pat. No. 7,645,874, US Pat. No. 5,914,003, and the like, but is not particularly limited thereto.
  • the tensile strength of the fabric is between 4 kgf and 25 kgf, more preferably between 6 kgf and 20 kgf. If the tensile strength of the fabric is lower than the above level can not be carded and powder shape, on the contrary, if higher than that can not be properly cut, there may be a problem that an unaligned part occurs when carding.
  • the method for producing a fibrous web according to the invention comprises carding a woven fabric.
  • the woven fabric is carded with a carded batt.
  • the woven fabric is fed into a machine with rotating cylinders with fine metal teeth and "brushed" through the cylindrical teeth.
  • the "brushed” web is then layered into bats on a take-up roller.
  • the bat may be about 5-10 layers, especially about 7 layers, of the carded web.
  • the density of the fibrous webs produced according to the invention is preferably 10 g / m 2 to 60 g / m 2 , more preferably 15 g / m 2 to 30 g / m 2 . If the density of the fibrous web is lower than the above level, there may be a problem in that the binding on the web is weak, so that it may not maintain a constant shape. On the contrary, the fiber web may be too bulky and may have a problem that web separation may occur when the web is laminated.
  • the method for producing fibrillated fibers according to the present invention includes calendering the manufactured fibrous web.
  • the density of the fibrillary fibers produced according to the invention is preferably between 100 g / m 2 and 600 g / m 2 , more preferably between 150 g / m 2 and 300 g / m 2 . If the density of the fibrillated fibers is lower than the above level, the hemostatic effect may be low, and if the fibril-like fiber is high, the binding force may be reduced, and the web may be separated during hemostasis.
  • the fibrillated fibers are for use as hemostatic or anti-adhesion agents, in particular hemostatic agents.
  • the method for producing a nonwoven fabric according to the present invention comprises the steps of: bonding the prepared fibrous web; And calendaring the bonded fibrous web.
  • the bonding of the fibrous web may be a method known in the art, for example, a needle punching method, a thermal bonding method, a melt blow method, a spunlace method, a stitch bond method and the like, but is not particularly limited thereto.
  • the fiber webs are joined by needle punching.
  • the carded bat is fed to a needle punching process in which a bed of baebed needles penetrates the bat when the bat passes through the machine. The barb-formed needles pull the bat fibers through each other, entangle the filaments in three dimensions and increase the structure density.
  • the bonded fibrous web is thus made into a nonwoven fabric through a calendering step as described above.
  • the density of the nonwoven fabric produced according to the invention is preferably between 50 g / m 2 and 600 g / m 2 , more preferably between 80 g / m 2 and 300 g / m 2 . If the density of the nonwoven fabric is lower than the above level, the hemostatic effect may be low, and if high, the entanglement into the needle punching may be reduced, thereby reducing the binding force, thereby causing separation of the web during hemostasis.
  • the nonwoven is for use as a hemostatic or anti-adhesion agent, in particular a hemostatic agent.
  • fibrillated fibers were formed through a calendering process under the conditions shown in Table 2 below.
  • Woven oxidized regenerated cellulose (ORC) obtained in Example 1 was properly arranged through a carding process under the following conditions to prepare a sheet-shaped web, and then bonded through needle punching under the conditions shown in Table 3 below. .
  • the density of the obtained nonwoven fabric was measured to be about 85 g / m 2 .
  • Example 2 In order to evaluate the hemostatic effect of the fibrillated fibers obtained in Example 1, a model small animal test in which the kidneys of rats were excised was performed. As a result, the mean blood loss value lost until hemostasis is shown in Table 4 below.
  • the fibrillary fibers according to the present invention show excellent hemostatic effect.
  • Example 2 In order to evaluate the hemostatic effect of the nonwoven fabric obtained in Example 2, a model small animal test in which the kidney of the rat was excised was performed. As a result, mean blood loss values lost until hemostasis are shown in Table 5 below.
