name: Kintra Fibers
description: 'Kintra Fibers is a Brooklyn, New York materials-science company that has
  developed a proprietary bio-based and biodegradable synthetic yarn as an alternative
  to conventional petroleum polyester. Its polymer is a novel form of polybutylene
  succinate (PBS) made from renewable corn- and wheat-derived sugar feedstocks, melt-spun
  on the same commercial equipment already used for polyester so that mills, spinners
  and extruders can adopt it without re-tooling. The company sells four physical products
  into the apparel supply chain — resin for extruders, staple fiber for spinners, 75D/72F
  multifilament yarn in FDY, ATY and DTY forms for mills, and finished performance fabric
  for brands. Co-founded by Billy McCall and Alissa Baier-Lentz, Kintra runs an in-house
  resin and fiber science lab in Brooklyn, launched a Fashion for Good consortium with
  Inditex, Bestseller and Reformation, and closed a funding round led by H&M Group. Kintra
  is a manufacturer of physical materials, not a software company: it operates no developer
  program, publishes no public API, SDK, webhook or machine-readable API contract, and its
  only web property is a Webflow marketing and contact site.'

  detail: Kintra Fibers manufactures a bio-based PBS polyester substitute sold as resin,
    staple fiber, 75D/72F yarn and fabric to extruders, spinners, mills and apparel brands;
    its only web property is a Webflow marketing site built on the off-the-shelf GENTLE
    e-commerce template whose /blog, /careers and /privacy-policy routes still return the
    vendor's lorem-ipsum placeholder copy, and every OpenAPI, GraphQL, MCP, llms.txt and
    agent-card path on it returns 404 while api.kintrafibers.com does not resolve at all.
