as tramas não tecidas compreendendo um polímero de a-(1,3 ¿ glucano) insolúvel em água e métodos de formação de tramas não tecidas são reveladas. o polímero de a-(1,3 ¿ glucano) insolúvel em água compreende 90% ou mais de ligações a-1,3-glucosídicas, menos do que 1% em peso de pontos de ramificação de a-1,3,6-glucosídico, um número médio de grau de polimerização na faixa de 55 a 10 000, e uma proporção de dpw aparente para dpw real na faixa de 2 a 10. as tramas não tecidas podem ser usadas para lenços de higiene pessoal, meios de filtração, vestuário ou outros usos. Nonwoven webs comprising a water insoluble α-(1,3→glucan) polymer and methods of forming the nonwoven webs are disclosed. The water insoluble α-(1,3→glucan) polymer comprises 90% or greater α-1,3-glycosidic linkages, less than 1% by weight of α-1,3,6-glycosidic branch points, a number average degree of polymerization in the range of from 55 to 10,000, and a ratio of apparent DPw to true DPw in the range of from 2 to 10. The nonwoven webs can be used for personal hygiene wipes, filtration media, apparel, or other uses.
